改善机井离心泵吸水性能试验研究

TEST FOR IMPROVING THE MOTOR-PUMPED WELL WATER ABSORPTION BY CENTRIFUGAL PUMP

利用射水器以水泵自身压力水作为动力来提高机井离心泵装置的吸水性能 ,解决超吸程离心泵机井在干旱季节无法正常工作 ,水泵汽蚀严重的问题 ,能使无法上水的离心泵重新上水。同时 ,可使井、泵在不同时期出水量均处于一个合理范围 ,从而使井泵安全运行。

The water absorption function of the motor-pump well instalation of contrifugal pump was improved by using shoot ware pump self pressure water as power by this method,the problems of exceeding inhale altitude of motor pumped well of centrifugal pump in dry season and pump cavitation can be therefore resolved.At the same time,the water amount absorped in different time can be kept in a reasonable scope and well pump will be run in a safety condition.
