Fault and treatment method of clean water centrifugal pump

Submersile pump

1. Pump does not absorb water, pressure gauge, vacuum gauge pointer pendulum:

 Reason: water injection pump is not enough, water pipes or instrument leakage steam. 
 Treatment: to pump water or tighten the plug leakage. 

 2. Pumps and suction vacuum gauge shows high vacuum :

 
 Reason: at the end of valve is not open or has been silted up and the water pipe resistance or the height is too large. 
 Treatment: correction or replacement of the valve, cleaning or replacement of water pipes, reduce water pipe height. 

 3. Pressure gauge pressure, but no water pipe :

 Reason: too large pipe resistance or impeller blockage, the direction of rotation error. 
 Treatment: check or shorten water pipes, check motor, clean impeller. 

 4. Low flow :

 Reason: water blockage, too much wear ring. 
 Treatment: cleaning pumps and water pipes, replace the mouth ring. 

 5. Pump internal sound abnormal, water pump is not lift water:

 Reason: too much traffic, suction pipe resistance or excessive height, leakage into the air, the temperature is too high. 
 Treatment: slightly off exit flow decreases, reducing resistance or high water, plug the leak, reducing the temperature of the liquid. 

 6. Pump consumes too much power :

 The reason: the stuffing extrusion tight, impeller wear, increase water supply. 
 Treatment: clean the stuffing, replacement of the impeller outlet pipe, increase resistance.
