7.3.2.2 tested.
No load test run of motor is usually carried out when motor is disconnected from
7.3.2.3 any load. No load test run requires 1-2 hours, observe whether there is any
7.3.2.4 phenomenon, abnormal noise and vibration, whether bearing is overheated or oil
leaks during this period. If the above-mentioned problems exist, solve them before
7.3.3 operation with load.
7.3.3.1
7.3.3.2 Full voltage startup and stepdown startup are permitted for motor.
7.3.3.3 No matter what startup method is used, if motor cannot start within 1-2 seconds,
cut off power supply immediately, check all possible causes, eliminate them, motor
7.3.3.4 and equipment might be damaged if motor is forced to start up before
troubleshooting.
7.3.3.5 Operation of motor with load
After no load operation is normal, coupling between motor and equipment may be
connected. Operation of motor with load may be tested.
Start up motor with load, note that if the motor fails to start up very quickly or run
smoothly, cut off power supply immediately, check whether installation is poor or
connection is incorrect.
If abnormal vibration occurs, possibly coupling center is not aligned, fixing bolt is
loose, rigidity of foundation is poor or the vibration may be transferred from other
machines and so on. Abnormal vibration will cause damaged of motor. Once
abnormal vibration is detected, stop running immediately.
If abnormal noise exists, possibly voltage is too low, load is blocked, load driven by
rotor is too heavy, electrical connection is not connected completely or the sum of
the above-mentioned problems. Abnormal noise will also cause damage of motor.
Once abnormal noise is detected, stop running immediately.
Please confirm that operating current is consistent with the rated current on
nameplate, and current of three phases is basically balanced. For motor with
winding rotor (YR series), also confirm that operating current is consistent with the
rated current on nameplate, and current of three phases is basically balanced.

7.3.3.6 Startup times of motor should be restricted according to technical requirements of
motor. Permissible startup times of motor mainly depends on load characteristics
and motor type. Too many startup times will cause motor to generate abnormal
high temperature, this will speed up againg of motor insulation, shorten service life
of motor or lead to accident.

(1) Twice startup in cold state is permitted.
(2) When motor runs for a long time or is in hot state, there should be a time interval

between shutdown and restart, continuous startup of twice is not permitted.
Generally, restart after more than 30 minutes is permitted when motor is in no load
condition; when motor runs with load, restart after 60 minutes is permitted.
Continuous inching of twice is equivalent to start once.
(3) In typical operating conditions, startup times of motor should be about 800 times
per year, subject to different powers.

7.3.3.7 For motor with thermosensitive element or PT100, when operating with load,
temperature of corresponding parts of motor must be recorded. Note that
temperature should not exceed permissible limit value of motor, temperature must
be measured continuously. To record temperature of motor, temperature of cooling
system should be recorded simultaneously, for example, temperature of air intake
and output (air-air cooler), water inlet temperature (water cooler).

Generally, temperature of winding and bearing becomes stable after motor has run with load
for more than 4 hours. This shows that motor goes into stable operation, if temperature of
winding still increases slowly, check whether load of motor is normal or not, whether there is
any overload.
If your equipment load does not reach motor power, record the load and temperature for
reference of inspection later.
7.3.3.8 After motor has run for some time, temperature of bearing becomes stable,

general requirement for bearing temperature is as follows:
1. Temperature of rolling bearing should not exceed 95 degree.
2. Temperature of sliding bearing should not exceed 90 degree.

When temperature of bearing exceeds the above-mentioned limit value, stop
motor immediately, do not restart motor before the cause is found out.
If the motor is not equipped with temperature measuring element PT100, temperature
should be achieved by measuring temperature of outer cover or end over of motor bearing (if
permitted after installation of equipment), generally, external temperature is 10 degree.
lower than actual temperature of bearing, however, pay attention to safety during
measurement using thermometer directly.
7.3.3.9 As far as bearing is concerned, its temperature rise speed could reflect whether
motor works normally or not more effectively than actually reflected bearing
temperature. If bearing temperature is found to increase very fast during operation
of motor, or there is abnormal vibration and noise, stop motor immediately, do not
restart motor before the cause is found out.
7.3.3.10 To start equipment with large moment of inertia, startup time of motor is relatively
long, if startup time is found to be very long, or abnormal noise is generated during
startup, please do not start motor forcedly. Contact with service personnel of
producing company.
7.3.3.11 When several motors use the same transformer simultaneously and capacity of
the transformer is not large enough, do not start up all motors simultaneously, start
them one by one from large to small.
7.3.3.12 During operation of motor and equipment, including finding out the cause of
abnormity, all protective devices of equipment should not be disconnected.
7.3.3.13 Observe closely in initial days of equipment operation with load, note whether
temperature and vibration changes, whether noise is abnormal.
7.3.3.14 For motor with vibration monitoring device SPM, after motor has run for some time,
measure vibration and shock pulse value, and keep record.
If SMP vibration monitoring device is not provided, vibration measuring instrument may be
used for inspection, measuring position cannot be the one specified in motor specification
due to connection of motor and equipment, measurement may be carried out on exposed

part of motor, however, measurement should not be performed on fan housing etc thin

sheets.

After motor is installed and connected with equipment, vibration value will be larger than that

upon delivery of motor correspondingly, control it with reference to the value below.

Foundation form Motor center height Vibration speed

mm/s

Rigid foundation Below H355 3.5

Rigid foundation 2P below H355 4.5

Rigid foundation Above H355 4.5

Rigid foundation 2P above H355 5.0

Flexible foundation Below H355 4.0

Flexible foundation 2P below H355 5.0

Flexible foundation Above H355 5.0

Flexible foundation 2P above H355 6.0

When this value is exceeded, or vibration is irregular vibration, please find out cause, if it

cannot be determined, please contact user service department of Hwada Company.

7.3.3.15 For slip ring motor, check whether spark is generated on slip ring during operation

with load, if there is spark, it shows that contact is poor, motor should be shut down

for adjustment.

7.3.3.16 After equipment has run for some time with load, check heat exchange system,

especially motor using water cooling, check whether there is any leak or blockage,

eliminate if there is any.

7.3.3.17 When motor is running with load, temperature on surface of some motors might be

very high, all operating and maintenance persons should avoid contact with hot

surface.

Note: pay attention to operating condition of motor when motor is running, shut down
if abnormal noise and vibration is generated, check the cause of abnormal noise and
vibration, do not start the motor before troubleshooting.

Possible cause of abnormal noise and vibration might be loose erection bolt on motor
and equipment, misalignment of connection, defective st ator coil, open circuit of
power supply in certain phase, unbalance due to failure of rotor component etc.

7.3.4 Shutdown
7.3.4.1 Shutdown is different, subjects to load driven by motor, however, main precautions

are consistent.
7.3.4.2 Unload, reduce motor load to minimum.
7.3.4.3 Cut off power control switch.
7.3.4.4 For motor with heating device, if not interlocked with main power switch, power on

the heating device.
7.3.4.5 For water cooling motor, cut off cooling water supply.

8 Lubrication of motor

Correct lubrication of motor will influence service life of bearing directly, and will also

influence service life of motor. It is very important to fill lubricating grease (oil) to motor

OP

bearing properly and periodically.

8.1 Lubrication of motor using rolling bearing
8.1.1 We use double sealed bearing (“ZZ” is attached behind model of bearing) for miniature

motor, this kind of bearing is pre-oiling type, re-filling is not required.

8.1.2 For large motor (generally H180 and above) and motor with specific requirement, oil

filling/draining device is designed, these motors have been filled with oil upon delivery,

however, grease should be replaced periodically.

8.1.3 For motor that has been stored or out of use for more than two months, grease must

be replaced again for bearing after motor is started. New grease must be filled in while

motor is running, fill grease until old grease is discharged from oil draining device.

Refer to 8.1.5 for grease filling method in details.

At initial stage of oil filling, too much grease might cause increase of bearing temperature,

this is normal, with discharge of old grease, temperature will be reduced to normal

temperature.

8.1.4 Normal cycle for grease replacement subjects to motor size and service condition, but

the longest oiling cycle should not exceed one year.

Suggested oiling values for motor are given below (excessive or frequent oiling might also

damage the motor)

Rated power Revolution of Suggested oiling cycle

(kW) motor Normal condition Harsh condition Severe

(rpm) condition

<18.5 1500 5 years 3 years 1 year

18.5-90 1500 1 year 6 moths 3 months

200-630 1500 3 months 1 month 15 days

<18.5 3000 5 years 3 years 1 year

18.5-90 3000 1 year 6 moths 3 months

90-200 3000 3 months 1 month 1 month

200-630 3000 3 months 1 month 15 days

Note:

Norma condition: work at rated or lower than rated p ower in clean environ ment,
running time per day is within 8 hours.

Harsh condition: work at rated or lower than rated po wer, 24 hours per day. Or in
relatively dirty and dusty environment. Or motor withstands vibration or light impact
load.

Severe condition: in ver y dirty and dusty environment, or subject to heav y impact
load and large vibration.

8.1.5 Grease filling method
1. Open dust cap on oil nipple and oil outlet, confirm that oil nipple is clean, use manual

oil gun or pneumatic oil gun to fill grease into oil nipple, until new grease is discharged
from oil outlet.
2. Take off oil gun, let motor run 10 to 20 minutes, confirm that surplus grease has been

O

discharged, put on dust cap of oil nipple and oil outlet, oiling is finished.
8.1.6 Type of lubricating grease
Use correct lubricating grease. If grease filled is incompatible with original grease, this will
reduce service life of bearing greatly.

The manufacture company specifies lubricating grease brand for bearing of motor that may
be filled with oil, Chevron Caltex SRI-2 (imported bearing), Jinzhi lubricating grease No. 2 for
bearing of medium and small size motor (domestic bearing), or brands determined jointly
with customer.

Special attention: if oil is filled in motor which is running, it must be done by trained
person, live parts and rotating parts should be protected completely.
Please note the brand of bearing lubricating grease, filling time and quantity indicated
on auxiliary nameplate of motor.

8.2 Lubrication of motor using sliding bearing
8.2.1 There is no lubricating oil in motor using sliding bearing upon delivery, oil must be filled

before use of motor.
8.2.2 Thin oil station that uses forced circulating cooling must be powered on. Thin oil station

of lubricating oil must be started before starting of motor.
8.2.3 Observe rotation of oil ring during operation of motor, if oil ring does not move, stop

motor immediately, because immobility of oil ring will damage bearing.
8.2.4 Check and confirm that no friction occurs between rotating parts and stationary parts in

the bearing.
8.2.5 Check oil level in bearing through observation hole, oil level line is provided for all

sliding bearings, generally in the center of observation window, when oil level is in the
position of oil level line, it shows normal oil quantity, if oil level exceeds oil level line, but
could still be seen in observation window, this is also OK.
8.2.6 For sliding bearing using forced circulating cooling, normal oil supply pressure is
120kPa ± 20kPa. Such pressure could ensure work of bearing effectively. Higher
pressure is unnecessary, on the contrary, too high pressure might cause oil leakage.
8.2.7 A very critical issue in use of sliding bearing is to measure oil temperature regularly,
especially self-circulating sliding bearing. If temperature of bearing increases suddenly,
stop motor immediately. Do not restart the motor before the cause is found out
thoroughly. If cause cannot be found out, please contact user service personnel of
manufacture company.
8.2.8 Generally, lubricating oil should be replaced immediately after testing of motor is
finished or after the motor has run for several days, because foreign bodies might exist
in bearing, pipeline etc, so it is very necessary to replace lubricating oil after use for
several days. Replaced lubricating oil may be reused after eliminating abrasion
particles and foreign bodies using filtration method.
8.2.9 For self-circulating sliding bearing, lubricating oil must be replaced after running for
about 6 months. For frequently started or 2P (revolution is above synchronous speed
3000 rpm) motor, time interval for replacement of lubricating oil should be shortened. .

9 Inspection and maintenance

In order to ensure continuous, safe and reliable use of motor, always check and maintain
motor timely, find out hidden troubles to prevent spreading of failure. Since motor is the
power for the whole equipment, especially large scale motor is even the heart of entire
system, timely and effective maintenance could ensure reliability and normal service life of
motor.

9.1 Purpose of inspection and maintenance
9.1.1 Ensure reliable operation of motor.
9.1.2 Minimize down time of motor, play an active role.
9.1.3 Some initial failures may be detected, and eliminated, so as to avoid spreading of

9.3.1 Routine inspection during operation of motor
The purpose of routine inspection during operation of motor is to determine whether
motor is running normally.

9.3.2 Periodic inspection of motor
The purpose of periodic inspection for motor is to prevent occurrence of failure, so as to
ensure use of motor and extension of service life.
9.3.3 Maintenance of motor
No matter the motor is in whichever service condition, after use for some time, motor must
be maintained. Subject to operating environment and conditions, maintenance cycle of
motor cannot be unified, however, periodic maintenance time of generally about one year is
required. For use in very severe environment or outdoors, maintenance cycle must be
shortened.
While considering maintenance cycle, the following factors must be taken into consideration:
(1) Environmental condition influences use of motor directly, motor must be maintained

regularly when ambient humidity is high or in dusty place, especially daily dust removal
is very important.
(2) Frequent startup, exceeds generally specified startup frequency.
(3) Service condition of wearing parts, such as bearing and slip ring.
(4) Frequent fluctuation of supply voltage.

OS

(5) Shock of driven equipment.
(6) Function of motor on the whole system.

9.4 Routine inspection during operation of motor
Special attention:
If any noise and vibration increases sudde nly or is too high, stop the motor
immediately and check quickly.
Check temperature of bearing periodically during continuous operation, at least once
per day.
9.4.1 Keep the motor clean regularly, prevent oil, water etc from entering inside of motor.
9.4.2 Keep good ventilation for motor, keep air inlet/outlet clear, mesh of fan housing should

be cleaned up regularly to prevent blockage.
9.4.3 Motor should be monitored regularly during operation, if there is any abnormity, shut

down immediately and check it, motor may continue working only after
troubleshooting.
9.4.4 Check whether play pointer of sliding bearing is in specified scope, if it exceeds the
specified scope, this means that friction exists between shaft and bearing, shut down
immediately and check it.
9.4.5 Shutdown inspection of motor
Shutdown inspection is required when any of the following conditions occurs:
(1) Motor vibrates severely;
(2) Equipment driven by motor is damaged;
(3) Heating of motor bearing is serious;
(4) Shaft travel impact occurs on motor;
(5) Speed of motor decreases suddenly;
(6) Scrapping occurs in motor, or temperature of enclosure increases rapidly;
(7) Motor or starting device generates smoke and is fired;
(8) Unexpected personal accident occurs.

9.5 Periodic inspection of motor
9.5.1 Motor should be checked according to service condition of motor.
(1) Check whether fixing bolt of motor is loose or not, or whether there is rust on fixing

bolt, which influences fixing performance.
(2) Check whether electrical connection is secure, whether there is rust etc that might

influence contact performance.
(3) Check whether critical connection of slip ring of motor with winding rotor (YR series)

is secure, whether slip ring and brush are worn.
(4) Check whether grounding of motor is secure, whether there is any rust etc that might

influence grounding performance.
(5) Check whether shaft seal of motor is aging, if aging or worn, make replacement.

(6) Check whether coupling is fixed securely and aligned correctly.
(7) Check whether there is any liquid which is harmful for performance in the motor,

eliminate it if there is any.

OT

(8) Check bearing of motor, if it is worn, replace it immediately.
(9) Check painting of motor, repaint if required, so as to prevent too much corrosion.

9.6 Maintenance of motor
Motor should be maintained periodically, if there is any failure, deal with it timely. In general
condition, carry out minor maintenance once per month, comprehensive maintenance once
per year. Content of maintenance includes the following aspects.
9.6.1 Items of minor maintenance include:
(1) Eliminate dust on the surface of motor;
(2) Measure insulation resistance of motor;
(3) Fasten fixing bolt and grounding bolt, and various connecting bolts;
(4) Clean up starting device and insulated terminal;
(5) Remove dust, carbon etc on slip and brush part of motor with winding rotor (YR

series);
(6) Clean up mesh of motor fan housing, ensure air inlet and outlet to be clear.
9.6.2 Items of comprehensive maintenance includes:
(1) All items of minor maintenance;
(2) Internal cleaning of motor, so that motor stator winding is clean without oil stain,

without exposed copper;
(3) Whether motor bearing is in good condition, if it is damaged, make replacement

immediately. In normal service condition, it is suggested to replace bearing once per
year (yearly operating time is about 8000 hours);
(4) If it is unnecessary to replace bearing, clean the bearing and replace lubricating
grease;
(5) Clean or replace other parts of motor.

9.7 Upkeeping method of motor
9.7.1 External cleaning of motor
External cleaning of motor is as important as internal cleaning, it influences operating
performance of motor directly, any negligence of external cleaning for motor is unfavorable
to long-term stable operation of motor.
(1) Fully enclosed motor (degree of protection above IP44), including air-air cooler

motor, must be cleaned up regularly, including air inlet/outlet duct and surface of motor,
it is especially important to keep outer fan of motor clean regularly, because dust
deposited on fan during use will generate unbalance unfavorable to motor operation, it
might generate vibration in worse condition.
(2) If motor works in location where long fiber exists, clean up fiber accumulated on
motor surface and vent opening periodically.
(3) For open motor (ODP motor with degree of protection below IP23), air inlet should
be cleaned up regularly to avoid dust and other foreign bodies blocking the air inlet
and influencing normal circulation of air.
Note: when carrying out extern al cleaning fo r motor, remember not to clean while
motor is running or remove external parts, so as to avoid foreign bodies being sucked
into motor.

OU

9.7.2 Internal cleaning of motor
After motor has run for a long time, dust, grease and carbon powder will inevitably exist in
motor (for slip ring motor, due to abrasion). Such articles tend to absorb moisture and lead to
decrease in insulation resistance of coil, dust deposit reduces cooling effect and leads to
temperature rise, in worse case, accident might occur on motor, so it is very important to
clean up inside of motor periodically, this is an important action to ensure long-term safe
operation of motor.
Internal cleaning methods for motor are as follows:
(1) Use industrial suction cleaner to clean inside of motor, dust and other broken articles

in motor may be eliminated. Its main advantage is that dust and other broken articles
will not fly away while cleaning inside of motor, so this will not include other motors. It
is very important that suction pipe of industrial suction cleaner must be nonmetal, so
that insulation of winding will not be damaged.
(2) Use compressed air to clean inside of motor, however, attention must be paid to
dryness of air, compressed air containing moisture will influence insulation of motor. At
the same time, note that pressure of compressed air should not be too high, generally
4kg/cm2. Too high pressure tends to damage insulation of coil, too low pressure could
not achieve good cleaning effect, so pressure of compressed air must be controlled
correctly.
(3) Use soft cloth to clean inside of motor, note that articles like cotton waste and
chemical fiber should not be used for cleaning, because they will stick fiber in motor or
surface of coil, which influences cooling of motor.
(4) If there are petroleum substances such as grease in motor, use cloth with petroleum
solvent (solvent will not drip) to wipe off.
(5) For motor used in hazardous environment, if petroleum solvent is used to wipe
inside of motor, pay attention to safety. When safety cannot be guaranteed, do not use
this method. Use incombustible solvent to wipe off or move the motor out of hazardous
environment for maintenance.
(6) Pay attention to safety precautions when cleaning the motor. Especially when
petroleum solvent is used, always keep ventilation around motor.
(7) For motor with radial ventilation structure, special attention should be paid to
cleaning of ventilating slot, blockage of ventilating duct will influence temperature rise
of motor.
9.7.3 Cleaning of rolling bearing
Motor bearing must be cleaned after running for a long time.
(1) Clean petroleum solvent must be used for cleaning. Cleaning should be performed
for generally three time, then use clean cloth to wipe the bearing.
(2) Provide anti-dust protection for bearing during cleaning and wiping, so as to prevent
invasion of dust and other tiny articles.
(3) Cold pressing technique is the best way to assemble bearing, but common user has
no such equipment, it may be heated by warming. Bearing may be heated in cleansing
oil, temperature should be controlled at 90 . If heating method is used to heat bearing,
note that after heating, end cover may be mounted only after bearing is completely
cooled down.

(4) It is prohibited to use any tool to knock the bearing directly for installation, similarly,
do not install end cover by knocking, because the result of knocking is damaged
bearing.

9.7.4 Cleaning of sliding bearing
(1) Judgment for cleanness of sliding bearing

Color of lubricating oil, if color changes.
Deposit is generated, such as bonding sheet of oil.
Viscosity is too high or too low, it is generally controlled within ± 15% of standard
requirement.

Determine whether oil deteriorates by snuffing at its smell, sour taste and other
abnormal tastes show that oil deteriorates.
(2) Cleaning methods of rolling bearing
When condition of Article (1) occurs on sliding bearing of motor, oil must be replaced,
bearing must be cleaned.
Sliding bearing must be cleaned using kerosene. Before refill new oil, confirm that kerosene
has been discharged completely.
(3) Precautions for cleaning of sliding bearing
Since bush of sliding bearing is made of Babbitt metal, be very careful in removal and
cleaning process, any knocking might damage bush and insulation finish of bearing.

2. General information

• Grease is automatically or manually delivered to 4 lubrication points by this
central lubrication system.

• The plant comprises：

- 1High-pressure central lubrication pump type 4DDB-M8

- 4 outlets (use for 4 shaft-end sealings)
- Control system used for additional grease
- Various mountings, pipelines and screw connections

• The central lubrication system is controlled by the electric switch and control
cabinet and must be incorporated into the overall control system (user-provided),
so automatic lubrication program is active when starting the mxier.

• The automatic lubrication control system must interlock with additional
lubrication system.

Function at local mixer

• Additional lubrication should be done after each shift, switchovering to
additional grease option, then press the start button on the control cabinet in the
mixer, the system shall re-grease to the shaft ends as per the setting time, and
at the same time ensure that the main shafts of the mixer is in the state of
rotation, so it may ensure the sealings to get well-proportioned and adequate
lubricating, and then hand labor-saving for greasing is achieved.

Function at remote side of customer

• Procedure of automatic control by customer

- When the mixer starts, meanwhile, the customer’s automatic programme is
activated accordingly. After expiry of the pause times set, the lubrication
pump starts working and delivers the correct amount of grease
predetermined by the cycle duration.

- The grease level in the reservoir of the central lubrication pump is
monitored both remotely and locally at any time . An “empty“ signal on the
local alarm unit is transmitted as soon as the minimum grease level has
been reached, and the remote alarm system will also start.

3. Lubrication points

Inner sealing chambers and/or labyrinths in front of the axial face seal (4 pcs).

The function of these sealing chambers is to protect the axial face seals from
the material (e.g. cement slag) penetrating the mixing chamber. It is necessary
to supply grease to these compartments and/or refill the grease chambers with
fresh grease via press button assembly“additional lubrication“ immediately
after cleaning the mixer.

4. Setting of parameters

IMPORTANT！
If mainly highly liquid products are mixed, we recommend to adjust the
lubrication intervals at automatic operation, which means shorter pause times
and/or more distributor running time.

bd00023

In case the preset number of distributor valve cycles must be adjusted for the
manually controlled “additional lubrication“, the user may readjust the timer to
set time on the control cabinet supplied with the mixer.

7. Maintenance / Inspection

IMPORTANT！
Using a central lubrication system does not release you from making regular
bd00023 checks.
The interior of the mixing trough shold be inspected visually once every week
to verify whether grease has come out of the labyrinths arranged around the
mixing shaft after completion of the additional lubrication process, which has
to be started after each cleaning process.
In case of multiple shift operation or when mixing mainly liquid products, this
must be repeated accordingly.
If no grease has escaped, the amount of grease for additional lubrication
should be adjusted accordingly (see section 3.2).
An increased wear in the area of the labyrinths can cause – besides other
reasons – an increased grease requirement.

In case that grease overflowing is found, which means grease line is
blocked, then it is necessary to dismantle the grease pipeline and clean
the inside with high-pressure air and ensure to be free of the blocking.

If the problem is not solved yet as instruction mentioned hereinbefore ,
the inside of the shaft sealing retainer must be checked and cleaned ,till
the grease flowing is smooth.

8. Installation

8.1 Installation of central lubrication system already fitted to the mixer

We recommend to have the installation carried out by a skilled fitter.

• Laying of the connecting cable with the specified operating voltage
(see installation instructions and technical description of control unit).

• Connecting remote control (interrupted oil supply, oil level control,
interlock) to the switch cabinet.

• If the cabinet of the central lubrication system is not directly fitted to the
mixer, you must lay the connection cables for pump motor, empty
signal – grease reservoir from the terminal box at the mixer to the
control cabinet and to the proximity switch of the progressive
distributor.

• We recommend to install the following signals and/or switches in the
control room of the entire plant.

- Signal lamp for „Fault“
- Signal lamp for „Reservoir empty“
- Signal lamp for „Pump ON“

8.2 Filling of the pump grease reservoir

• Grease should be filled into the pump reservior through nipples to
avoid impurities.

• Since empty/full level is controlled by position sensor, make sure that
there is no grease on the vessel lid in the area of the position sensor
when you fill the pump reservoir in order to ensure the function of the
indications.

• In order to be able to recognize the maximum grease level when the
reservoir lid is closed, the full level signal is installed in a red indicator
light at the terminal box close to the grease lubrication pump to be able
to stop the grease replenishing system in a timely manner.

• In case of a permanently incorporated automatic grease replenishing
system the filling action can be automated.

4DDB-M8
1. Application and characteristics
4DDB-M8 is a grease plunger pump with high pressure and multiple lines. This pump has 8
removable output ports at most. Each output port inside the pump is assigned a delivery piston of
its own that simultaneously meters the lubricant (adjustable). Each output port has independent
pressure protection. Equipped with high grease level & low grease level indicator, 4DDB-M8 leads
directly from the pump to the lubrication points or to a progressive feeder that further divides up the
respective delivery rates of the connected outlet ports. It’s easy to use and maintain. 4DDB-M8 is
applicable for the centralized lubricating systems in all types of heavy machines.

4. Structure and working principle
4DDB-M8 is a plunger pump (D2,drawing 2). The motor directly connects reducer (1) to make
eccentric shaft (2) rotate. The driven plate (3) on eccentric shaft to force the plunger of each pump
unit (4) to move back and forth alternately, in turn to complete the suction and discharge process.
When the plunger discharges grease, the slide valve (5) is opened, then the grease is charged
from the hole of slide valve.
Each pump unit is equipped with safety valve (8) and check valve (6) independently to avoid
overload and pressure interference during the operation. Toroid (11) on squeezing plate (14)
triggers magnetic switch(12) in center pole (10) to indicate the high level or low level of the grease.

5.4 When the pump runs for the first time or it starts to run after long-term closing down, the old
grease in reservoir should be cleaned out and new grease should be filled.

5.5 Grease should be filled from the special input port. Grease should be clean, without any
impurity or air bubble. Grease level indicators to be installed in the reservoir. Input port is
equipped with quick plug-in joint if SJB-10ZA grease pump with manual feeding is used.
Adapter has to be used to feed grease if the other pumps are selected. Rubber cap should
be covered the quick plug-in joint after the grease filling is finished.

5.6 Inner holes of all pipes in lubricating system have to be cleaned. Pipe joints should be used
as few as possible and lubricating pipe should be bent as little as possible. Lubricating
pipes should be fixed by clamp.

6. Use and maintenance
6.1 Before the pipes/tubes are connected with the lubrication pump, the pump should run
in for 5 minutes to ensure the normal operation of the pump.

6.2 Each pump unit has safety valve. The protection pressure of 4DDB-M8 has been set to
28Mpa. When user adjusts the pressure of safety valve, pressure gauge has to be
installed on the pipe. Generally, user is not allowed to adjust the pressure of safety
valve.

6.3 Each pump unit has check valve to avoid the pressure interference during the
operation and grease circumfluence.

6.4 Joint of output is complied with G8 GB3733.1 (Drawing 3). Cold rolling seamless

6.5 Before the pipes/tubes are connected with the lubrication pump, the pump should run
in for 5 minutes to ensure the normal operation of the pump.

Grease should be filled into all lubricating points and distributors to ensure the
smooth flow. If necessary, all of the pipes/tubes should be filled with grease before
connection.

6.6 Each output port can be used in parallel in order to meet the demand of lubrication
point. In order to increase the number of lubrication points, all types of progressive
distributors manufactured by our company can be selected and used.

When poregressive distributor is used with the pump, pipes/tubes at the output port
of the progressive distributor should have the similar length. It’s not allowed to arbitrarily
jam output port of the progressive distributor.
