Deep well pump principle and type introduction
A vane pump to lift water from a well is called a deep well pump. It consists of three parts: the topmost motor is mounted on the wellhead ground; the middle is a water pipe and drive shaft; and the lower end is the working part of the well pump, submerged below the well surface. One of the long axis deep well pump is a more common type of well pump, which is mainly used in machine wells. Due to the well depth, the larger head is required. The lift range of the long axis deep well pump is 15 ~ 17 m. Deep well pump is generally multi-stage vertical centrifugal pump. According to the structural characteristics of deep well pumps, proper use and timely troubleshooting, to ensure the safe operation of deep well pumps, to extend its service life are very important.
