LUBRICATION SYSTEM FOR BEARINGS OF THE
DIESELGENERATOR
TYPE:HSG900XU I0
PROJ.NR.4673HC401-403
ITT1
\f .
FUNCTION :
BOTH BEARlNGS HAVE THE OWN OIL CIRCU LATrON THROUGH HEAT
EXCHANGER AND FILTER BY THE OIL PUMP.
THE MOTOR OF PUMP GETS POWER FROM AC-NET OF THE SH1P (3-PH.
480 V, 60 HZ)
.
IF TIIB OIL FLOW BECOME TOO SMALL SO TIIE FLOW SWITCH
RELEASES ALARM.
CONTROL OF THE OIL TEMPERATURE BY THE PT-100-DETECTOR IN
THE BEARING AND THE TEMPERATURE OF THE HEARING BY THE
PT-100-DETECTOR IN TIIB BEARING SHELL.
THE OIL RING IN TIIB BEARlNG MAKES RESERVE LUBRICATION.
ONLY BY THE OIL.RING LUBRICATION CAN THE GENERATOR RUN
ABOUT 10 ... 30 MINUTES DEPENDING ON THE ANGLE OF HEEL OF THE
GENERATOR ON AXIAL DIRECTION.
PARTS OF LUBRICATION UNIT:
- GEARED PUMP WITH AC-MOTOR
- OIL-WATER HEAT EXCHANGER
-OIL FILTER WITH INDICATOR FOR DIRT CONTENT
- OIL FLOW SWITCH
- BACK·PRESSURE VALVE
- CONNECTION HOSES TO ACCORDING DNV
- BASE FOR PARTS (THAT IS MOUNTED ON THE END- SHIELD OF
THE GENERATOR NEAR THE BEARING)

Mats,
Starting and running of the oil machine units: The oil pumps have to be
started approximately 3-5 seconds before the diesel. When starting the oil
pumps the temperature of the oil has to be at least +10 degrees celsius .
When the system is running the temperature of-the oil has to be at least
+25 degrees celsius. The bearings have been calculated so that the
normal temperature of the cold oil going into the bearings is +60 degrees
celsius, then the temperature of the bearing is approximately +70 degrees
celsius .
..
Stopping the oil machine units: The oil machine units can be stopped after
the diesel has totally stopped, so after the diesel and the generator do not
rotate any more.
Best regards,
~<<~

Dear Mr. Cederberg,
1) and 2) Please find attached revised oli lubrication sys~em drawings:

3) There are two different size of pumps because the D-end bearing can
take also axial load and it needs more lubrication oil-than N--end bearing.
But mechanically pumps and motors are interchangeable, so you need only
one type of pump an·d motor as a spare part the bigge~ one (0,75 kW motor
and puinp combination). So the bigger pump can be used also in the N- .
end. Do you think that the client can accept this explanation, because there
Is no difference In operation and after all the customer needs only one type
of spare parts, which fits to·both ends.
4) I will inform soonest the mechanical power of the pumps. ·
