摘　　要：为保证泵试验台准确地测量试验泵的水力性能,泵试验台所有的测量仪表均由相关检定机构进行了检定,并出具了相应的检定证书。选取压力变送器、电磁流量计和扭矩仪的检定证书进行论述,探讨如何将这三种仪表的检定证书应用到泵试验台的水力测量中,以提高泵试验台的准确度。其他仪表检定证书的应用方法可以参照执行。In order to ensure accurate measure of the pump′ s hydraulic performance at the pump test bench,all measuring instruments of the pump test bench had been verified by relevant verification institutions and corresponding verification certificates had been issued.The verification certificates of pressure transmitter,electromagnetic flowmeter and torquemeter were selected for elaboration,and the discussion was made on how to apply the verification certificates of these three instruments to the hydraulic measurement of the pump test bench so as to improve the accuracy of the pump test bench.The application methods of other instrument verification certificates could be implemented with this as reference.
