How To Operate A Pump ?
The Pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps.
Pumps operate by some mechanism (typically reciprocating or rotary) and consume energy to perform mechanical work moving the fluid. Pumps operate via many energy sources, including manual operation, electricity, engines, or wind power, come in many sizes, from microscopic for use in medical applications to large industrial pumps.
Pump Start-up Procedure
- Line up the pump valves.
- Ensure the casing drain valve is closed.
- Open the suction valve.
- Open the vent valve to bleed off gases – once liquid comes from the vent valve – shut it once more. (This is termed ‘Priming of pump’).
- Open the gland-seal valve (if fitted).
- Check the bearing with oil coolant systems (if it is available).
- if an oil bottle or ‘slinger-ring’ reservoir is employed for the bearings, guarantee it’s full and functioning properly.
- Check by Finger that the pump shaft is smoothly rotating – (power is Cut-OFF at this time).
- Energies or, if the rule applies, have the skilled worker energize, the power supply.
- The discharge valve, at this point, ought to still shut off.
- begin the pump motor. Ensure the pump is rotating within the desired direction.
- confirm the discharge pressure is maintained a fixed value – if not check at the vent and unharness from now on treed gas.
- Check for vibration, heating and/or any undue noise from the pump, bearings or coupling.
- Again check the fill-up and cooling systems & check for leaks at the pump glands. (With the ‘packed’ seal, a small amount of leak is acceptable for lubrication and cooling of the gland). Open the discharge valve
- Report back to the Monitoring room that the pump is operational and everyone is O.K. (If not O.K. -shut down the pump and have the room operator decision a maintenance mechanic).
