| The centrifugal pump works by centrifugal movement of water when the impeller rotates. Before starting the pump, the pump casing and suction pipe must be filled with water, and then the motor can be started to drive the pump shaft to drive the impeller and make the water perform high-speed rotation. The pressurized water line into the pump.
1. Check whether the pump vibrates abnormally. If vibration occurs, stop the pump immediately for inspection.
2. Check whether the bearing temperature is normal. Too high temperature will accelerate bearing damage and shorten the service life of the pump.
3. Check whether the lubricating oil level is normal. If the lubricating oil expires, it needs to be replaced frequently.
4. Check whether the lubricating oil temperature is normal
5. Check whether the lubricating oil is qualified
6. Check whether the leakage meets the requirements. For serious leakage, please check whether the mechanical seal is damaged.
7. Check whether the sealing fluid operates normally
8. Check whether the sealing cooling medium is normal
9. Check whether the cooling water system is normal
10. Check whether the grounding of the motor is intact. Please pay attention to whether the grounding bolt is loose and tighten it in time.
11. Check whether the motor vibration is normal
12. Check whether the motor bearing temperature is normal
13. Check whether the motor current is normal. If the current is too high, the centrifugal pump will not work properly.
14. Check whether the pump inlet pressure is normal and stable
15. Check whether the pump outlet pressure and flow are normal and stable
