摘要
从水泵铭牌“规定性能点”和制造厂提供的扬程一流量特性曲线的允差出发,对水泵特性排量和流量仪表测量值之间出现差异进行了分析,论证某些水泵用户误用水泵特性值核对运行中流量测量仪表测量值,并以实例加以说明.
The deviation between the characteristic drain of the water pump and the measurement of the flow instrument is analyzed based on the 'prescribed functional point on the nameplate of the pump and the tolerance of the characteristic curve of lift vs. Flow offered by the manufacturer. It is expounded that certain users check the operational measurement of the flow instrument in a wrong way with the characteristic value of the water pump. It is stated with practical example too.
