新型射流式自吸喷灌泵的设计及试验

摘要

In order to improve the performance of flow-ejecting self-priming spray pump,a new type of flow-ejecting self-priming spray pump with a diffuser was designed and experiment study of the pump was carried out.The experiment results show that the performance of the pump meet the design requirements,compared with the self-priming pump (Honda pump) which has the same parameters,the new pump have obvious advantages.And,the self-priming time relative to the original pump with symmetric diffuser have dropped.%为改进射流式自吸喷灌泵的性能,设计了一种带不对称出口导流器的射流式自吸喷灌泵并进行了样机试验.试验结果表明:带不对称出口导流器的射流式自吸喷灌泵性能达到设计要求,对比同参数自吸泵(本田泵)其外特性参数有明显优势,同时其自吸时间相对于原带对称出口导流器的射流式自吸喷灌泵有了大幅下降.
