General Checklist the Essential Steps and precautions for Pre-start and Starting up the Centrifugal Pumps.
# What’s the things you Should be attention physically?
# 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.
