Deep well pump working principle

Working principle of deep well pump: The vane pump that extracts water from the well is called deep well pump. The long shaft deep well pump is a kind of common application in well pump. It is mostly used in the well. The deep well pump is composed of three parts: the top is the motor, on wellhead pipes and the ground is intermediate shaft lower end portion to the work well pump, submerged in the well below the surface. Since the well depth, require a larger head, the major axis deep well pump head range of 15 ~ 17 m. deep well pump is generally Segmented multi-stage vertical centrifugal pump. According to the structural characteristics of the deep well pump, correct use and timely troubleshooting are very important to ensure the safe operation of the deep well pump and prolong its service life.

Stainless steel multi-stage deep-well pump, which belongs to the technical field of pumps for deep water. The pump body and impeller are precision casted with a silica sol lost wax mold and 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 mounted on the shaft, the pump body and the shaft clearance are matched, and the impeller and the shaft are fixedly matched. The pump bodies of all levels are assembled on the shaft in turn, and the outer wall of the water pump is smooth and integrated. The motor drives the water pump shaft and the impellers of each stage to rotate synchronously. 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. When working, the pump body and impeller of each stage can have a lift of about seven meters, and multiple stages can meet some special needs. It has the characteristics of corrosion resistance, long life and high processing precision, and can be produced and assembled according to customer and market demand levels.
