| 摘 要： | 介绍了自吸混流泵的工作原理、结构特点及设计要点。前置式自吸混流泵是在水泵叶轮前端，由Ｓ形泵盖与液环轮共同组成的自吸装置米实现泵的自吸．用这种方法可以简单方便地将任何前开门式单级离心泵和混流泵改成自吸泵，且不影响泵原来的主要性能．

| Abstract: | This article describes the principle of operation,peculiarity of its construction,and the keys of design of the self-priming mixed flow pumps.The self-priming is realized bysetting a self-priming device composed of S-formed cover and liquidring weel in front of pumpimpeller. By means of this practice all single-stage and single-suction vane pumps with frontinlets can be modified into self-priming pumps without damaging their original principal per-formances. |
