General centrifugal pump start up procedure:-
Before pump start-up you must perform
these tasks:-
*01.
Open the suction valve , do priming by
venting all the air inside the suction line by opening any vent or even the PG
vent till liquid coming out then close , now you confirm no air inside the
system to reduce the chances of pump getting cavitation
*02.
Open any re-circulation or cooling lines.
*03. Fully close or partially open the discharge
valve, depending on system conditions.
*04. Start the driver.
*05.
Slowly open the discharge valve until
the pump reaches the desired flow.
*06.
Check the pressure gauge to ensure that
the pump quickly reaches the correct discharge pressure.
*07.
If the pump fail to reach the correct
pressure, perform these steps:
a.
Stop the driver.
b.
Prime the pump again.
c.
Restart the driver.
*08.
Monitor the pump while it is operating.
a.
Check the pump for bearing temperature, vibration, amp/load and noise.
b.
If the pumps exceed normal levels, then shut down the pump immediately and correct the problem.
*09.
Repeat steps 7 and 6 until the pump runs properly.
