汽油机共轴泵测试系统和测试方法

The measuring system and method of gasoline engine coaxial pump

长期以来汽油机共轴泵都是进行单泵测试,只考核泵的性能,这就不能准确地反映机组性能。本文介绍汽油机共轴泵在试验室测试流量、扬程、转速、效率、汽蚀余量等主要性能参数的测试系统和测试方法,该测试系统和测试方法对汽油机共轴泵进行整个机组考核,全面反映机组性能,并通过多次测试验证,符合GB/T3216—1989《离心泵、混流泵、轴流泵和旋涡泵试验方法》的要求。

The property of co- axle gasoline pump unit has been evaluated only by test on pump for many years. So it cannot accurately show the property of gasoline pump unit. The article discusses the test system and test method of primary paramount of the machine such as flow, water height, etc. It is proved by verification test that the system and method completely conform with the techniaue standard GB/T3216-1989
