Standard requirements for pump test operation

2.Stuffing box or mechanical seal temperature, sealing liquid or cooling water temperature shall not exceed the provisions of the technical documents. The soft packing seal of the centrifugal pump can be made according to the different viscosity of the conveying medium, and the 5~20 drop /min is allowed to be uniform and drip leakage. The allowable leakage of mechanical seals shall conform to the provisions of the technical documentation. For conveying toxic, hazardous, flammable, explosive, precious materials and requirements of the medium and air isolated from the pump, the sealing leakage should not be greater than the specified value of the design. 

 

3.The relative density of the working medium is less than 1 of the centrifugal pump, when the water test run, should control the motor current should not exceed the rated value, and the pump flow should not be less than 20% of the rated value. 

 

4.Test run, motor temperature rise shall not exceed machines or technical documents; if there are no provisions, should be based on the insulation level to be determined. 

 

5.The rotor and the moving parts, no abnormal sound and friction phenomenon, the pump's vibration value should be in accordance with the provisions of the technical document; the allowable vibration of the plunger pump. The running of the reciprocating pump should be stable, and the steam distribution mechanism should be flexible and accurate. 

 

6.Pump auxiliary equipment operation should be normal, the pipeline should be firmly connected, no leakage phenomenon exists. 

 

7.Found the abnormal situation should be handled in a timely manner, the test running process should be recorded in detail and stored in the device
