随着人民生活水平的日益提高,对饮用水的质量提出了较高的要求.由于地表水易受污染,所以地下水的开发利用,正得到人们的关注,农村现在也越来越多地使用地下水。目前开采地下水的方式,大都采用深井、井泵、水塔、进出水管道组成的供水系统。井泵抽水一般用人工开机操作,由专人看管,工作时间长,供水受人为因素制约.也有采用浮球式液位装置自动抽水,但是安装比较繁琐,维护保养不便,受自然环境影响,长时 With the increasing living standards of the people, higher demands are placed on the quality of drinking water. Because the surface water is susceptible to pollution, the development and utilization of groundwater is receiving attention, and rural areas are also increasingly using groundwater. . At present, most of the methods for exploiting groundwater use the water supply system composed of deep wells, well pumps, water towers, and inlet and outlet water pipes. Well pumping is generally operated by manual operation. It is attended by special personnel. The working time is long and the water supply is restricted by human factors. There is also a float type liquid level device for automatic pumping. However, the installation is cumbersome, the maintenance is inconvenient, and it is affected by the natural environment.
