摘要
水文地质勘查进行抽水试验,对于安装了深井潜水泵的开采井若要做一个三次降深的抽水试验十分困难。笔者在试验中采用变频技术,通过加装一套变频装置改变输出电流频率,实现了一台水泵可调节流量完成不同降深抽水试验目的,试验效果良好。
In hydrogeological survey,it is very difficult to carry out a pumping test for a exploitation well fitted with a deep submersible pump to perform a drawdown pumping test for three times.In this paper,the author introduces a test that makes use of a set of frequency conversion device to change the output current frequency,so as to realize the purpose of the adjustable flow rate of a water pump to complete the pumping test with different drawdowns.
