在对外承包供水井中,有些井水位较深,水量偏小,空压机进行抽水出水不连续,如此情况,抽水试验难以进行,为此我们把三通应用在抽水中,达到了目的。我们的作法是:在井口安装三通,从潜水泵出来的水,进入三通后,一部份经出水管流出水外,一部分经回水管进入井内,加入循环中。通过调节出水管、回水管的流量控制阀门,
In the contracted water supply wells, some of the wells have deeper water levels and the water volume is smaller. The pumping water from the air compressor is not continuous. In this case, the pumping test is difficult. Therefore, we applied the three links to pumping water to achieve the purpose. Our approach is to install a three-way connection at the wellhead. After the water from the submersible pump enters the three-way connection, a part of it will flow out of the water through the outlet pipe, and part of it will enter the well through the return pipe and be added to the cycle. By adjusting the flow control valve of the outlet pipe and the return pipe,
