4. Operation
4.1 Test run
Follow the procedure (1) – (4) below to start operation of the Pump unit.
(1) Check the piping.
Check and ensure that the piping and cable connection is completed (Refer to the “3.4 Air Suction
Piping/Exhaust Piping” and “3.6 Electrical Connection”).
(2) Check the lubrication oil level (Refer to “3.3 Lubrication”).
(3) Check the Cooling water level (Refer to “3.5 Water Piping”).
Ensure that the Cooling water is flowing.
PRC-003A
→
Flow rate 2.0L/min or more
PRC-006A
→
Flow rate 2.0L/min or more
PRC-012A
→
Flow rate 3.0L/min or more
PRC-018A
→
Flow rate 3.0L/min or more
Check and ensure also that there is no cooling water leakage.
(4) Check the lubrication oil discharge operation and rotation direction.
a. Close the Suction valve of the Mechanical booster pump or put a Blind flange to the Suction inlet
to block it.
b. Run the Supplementary pump to exhaust inside the Mechanical booster pump. This time, confirm
that the pressure of the suction inlet or outlet of the booster pump comes down around the
ultimate pressure of the Supplementary pump (13.0-1.3Pa for the standard supplementary pump)
and keep exhausting three minutes or more only by the Supplementary pump under that state.
Exhausting three minutes shall deaerate the air component in the lubrication oil in the Mechanical
booster pump.
c. Flow the Cooling water and run the Pump around three seconds on keeping watching the Oil level
gauge to check the rotation direction.
Gear rotation shown in the Fig. 11 is correct.
If it rotated reverse, check the motor wire connection. The Motor is a three-phase induction motor
that would rotate reverse if two of three input wires were connected reverse.
d. Upon checked the rotation direction, run the Mechanical booster pump three minutes or more to
conduct the lubrication deaeration and lubrication circulation inside the Pump unit.
