汽油机水泵性能试验方法的研究

Research into the method of performance tests for petrol engine pumps

近年来,汽油机水泵作为一种重要的农林排灌机械,具有体积小、移动灵活、使用方便等特点,在我国广大农村地区应用越来越广泛。目前,汽油机水泵质量参差不齐,特别是流量和扬程等性能参数合格率低,一定程度影响了农业生产率的提高。泵的水力性能试验方法标准GB/T3216是直接引用ISO9906国际标准,它是关于回转动力泵水力性能的通用试验方法,主要是针对回转动力泵作为独立试验对象,并未考虑到水泵及其配套动力作为一个整体的情况,该文围绕汽油机水泵的特点对性能试验方法进行研究。

In recent years, petrol engine pumps are extensive used in vast rural area increasingly, as an important farming and forestry machine for irrigation and drainage, which have the characteristics of small volume, agility in moving and convenient for use. Presently, the quality of petrol engine pumps are ragged, for instance, the rate of eligibility for performance parameters as flow rate and pump total head is low. So which influences the agriculture productivity to a certain extent. GB/T 3216 is the test method for hydraulic performance of pumps, which is citing ISO 9906 directly, which is the universal hydraulic performance test method for rotodynamic pumps. Nevertheless, it is involved in the instance of rotodynamic pumps as unattached object, and no considering the instance of pumps and power as a holistic test object. The characteristic of general petrol engine is important way to research on the test method for performance of petrol engine pumps.
