Centrifugal pump basic performance test and curve drawing Author: strong industry Pump Published: 2017-10-26 15:01:15 Hits:
The basic performance curves of centrifugal pumps are HQ, NQ and η-Q. The unit can also be used for performance measurement and performance curve drawing for actual performance check.
The determination of the performance of a centrifugal pump is relatively easy to do in terms of its flow rate, head, power and efficiency. Generally speaking, the pump does not have to be removed, as long as the suction side page of the original device piping system can be kept constant, and the liquid medium can be cleaned with water (so that the measured performance index can be compared with the original specification performance index). The test instrument is also relatively simple, only a power meter, a pressure gauge, a vacuum gauge and a flow meter are sufficient.
