In this article, the centrifugal pump manufacturer Changsha Zoomlian Pump industry will share the daily maintenance specifications of single-stage single-suction centrifugal pumps for you, and summarize the four aspects and 13 sections of routine maintenance methods for your reference to ensure the normal operation and extend the service life of your single-stage single-suction centrifugal pumps.
1. Daily inspection and maintenance
Check the working state of the pump:
Regularly check whether the operation of the centrifugal pump is normal and whether there is abnormal noise or vibration.
Check whether the bearing of the pump is well lubricated and there is no leakage.
Check pump seal is good, there are no leaks.
Clean pump inlet and outlet and filter:
Clean the pump inlet and outlet and filter regularly, using a soft brush or high pressure water gun to thoroughly remove sediment and impurities.
Check and adjust the shaft alignment of the pump:
Regularly check the shaft alignment of the centrifugal pump to ensure that the shaft alignment is correct to prevent vibration and noise.
Check and tighten bolts and nuts:
Check and tighten the loose bolts and nuts frequently to ensure the stability of the pump structure.Keep the pump body clean:
Often wipe the liquid and dust or other dirt on the centrifugal pump unit and the centrifugal pump pipe to keep the pump body clean.
Second, regular maintenance
Change lubricant:
Replace the lubricant at specified intervals to ensure normal lubrication of the pump. If the centrifugal pump works within the first month, the lubricating oil is replaced after 100 hours, and the oil is changed once every 500 hours.
Check and replace seals:
Regularly check the wear of the seal, if there is wear or aging should be replaced in time to ensure the sealing performance of the pump.
Check and replace bearings:
Check bearing wear regularly, such as wear should be replaced in time.
Cleaning filter and inlet:
Clean the filter and inlet of the pump to ensure the normal operation of the pump.
Three, seasonal maintenance
Winter maintenance:
In winter, it is necessary to drain the residual water in the pump in time to prevent ice damage to the pump.
Summer maintenance:
In the summer, keep the cooling system of the pump unblocked to prevent overheating damage to the pump.
Iv. Other precautions
Lubrication system:
Pay attention to the quality and type of lubricant, choose the lubricant suitable for the pump.
Mechanical seal:
It is strictly prohibited for the mechanical seal to work under dry grinding conditions, and ensure that the lubrication of the mechanical seal should be clean and free of solid particles.
Start and stop:
Before starting, the pump (motor) should be turned several times to avoid breaking and damaging the sealing ring.
Stop the use, first close the gate valve, pressure gauge, and then stop the motor.
Control flow and head:
Try to control the flow and head of the centrifugal pump within the range indicated on the label to ensure that the centrifugal pump operates at a high efficiency point.
Through the above daily maintenance specifications, the normal operation of the single-stage single-suction centrifugal pump can be ensured, its service life can be extended, and the possibility of failure can be reduced.
