Today, Shanghai Shenquan will give you a brief explanation of the problem of pipeline pump evacuation, please follow along to take a look at the following content.
Causes and solutions for the evacuation of pipeline pumps:
1. Air leakage occurs at the inlet of the water pump.
Solution: The pump should be stopped to check the leakage inlet pipeline and flange of the pump.
2. Blockage occurs at the inlet of the water pump.
Solution: The pump should be stopped to check the leakage inlet pipeline and impeller of the pump, and then purged for maintenance.
3. The pressure at the inlet of the pump is not enough.
Solution: The back pressure of the liquid level should be increased.
4. The medium temperature at the inlet of the pump is too high, and the saturated steam is too large.
Solution: The temperature of the medium should be reduced, and the steam in the pump should be emptied and discharged.
5. The inlet valve of the water pump is not opened or the valve core falls off.
Solution: The valve should be opened or the pump should be replaced for maintenance.
6. The opening of the pump outlet is too large (small).
Solution: The opening of each valve should be adjusted appropriately.
7. The water pump seals the oil with water.
Solution: The sealed oil tank should be dehydrated.
8. The liquid level in the pump tower or container is low or there is no liquid level.
Solution: The outlet valve of the small pump should be temporarily closed or the pump should be stopped, and the liquid level should be restored after rising.
9. The impeller or internal grinding ring of the water pump is seriously worn.
Solution: Replace it in due course.
10. The pump motor is reversed.
Solution: The motor steering should be adjusted in time.
