Submersible pump is the pump shaft and motor directly connected to form a whole pumping unit R. the whole pumping unit is submerged in the water. 1: the water extracted by screw pump is transported to the ground return water tank through the lifting pipe. Because there is no long drive shaft, so the submersible pump is light in weight and small in size, which is easy to install and shift work. In recent years, submersible electric pump has been widely used in ziqu District of our country.
The submersible electric pump (Group 3-1) is a centrifugal pump and a motor made into a whole, which is placed in the well water together. On the ground, the motor is connected with the power supply through the cable to drive the impeller of the pump to rotate. It has the advantages of simple structure, small volume, light weight, convenient installation and maintenance, safe operation, overstaffed operation and good performance. It is a new type of water lifting machine with high efficiency and low investment. It can be widely used in water supply and drainage of industrial and mining enterprises, urban water supply, farmland irrigation and drinking water for people in water shortage areas.
