Deep well pump principles and types

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 used, used for the well. 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. Stainless steel multi-stage deep well pump, belonging to the technical field of a pump for deep well water withdrawal. Pump body and impeller is the use of silica sol lost wax mold precision casting, the material is stainless steel. The structure comprises a pump body, an impeller and a shaft, each stage is composed of a pump body and an impeller, the impeller is contained in the pump body, the pump body and the impeller are respectively arranged on the shaft, the pump body is matched with the shaft clearance, the impeller is fixedly matched with the shaft, , At all levels of the pump body mounted on the shaft, the pump wall smooth into one, driven by the motor shaft and all levels of impeller rotation. The upper end of the pump body is provided with a water outlet valve body, and the lower end of the pump body is provided with a motor seat. Work, each level of the pump body and impeller can have about seven meters of lift, multi-level series, will be able to meet some specialized needs. Its corrosion-resistant, long life, high precision machining, according to customer and market demand for production and assembly level.
