Each pump at the factory should be at the design speed of the performance test and run the test. How to test the pump? Performance test of the pump should be carried out at five different flow rates (including 110% of the shut-off point, the minimum continuous flow and design capacity in order to get a reasonable performance curve Pump mechanical operation test: In the performance test After the mechanical continuous operation test should be carried out under design conditions to check the mechanical operation, the inspection time is usually one hour. When the test equipment can not be operated at the design speed, the test speed may be different from the designed speed, and the variation range is The rated speed of the demolition of the necessary if necessary, the initial test results are invalid, the final test shall prevail. Pump performance curves and data include: total head, efficiency, shaft power and speed and correction calculation, to make HQ, PQ, curve Vibration and temperature rise; noise measurement; NPSH test; Note: The above content from the network.
