Deep well pump working principle introduction Deep well pump working principle is to raise water from the well vane pump, long shaft deep well pump is a more widely used deep well pump, a pump, generally used for machine wells. Deep well pump is mainly composed of three parts: the top is the motor, installed in the middle of the wellhead is the working part of the water pipe and drive shaft at the bottom of the deep well pump submerged in the well below the surface water. Due to the well depth, the larger head is required. The lift range of the long shaft deep well pump is generally 15-17 m. Deep well pump can be divided into multi-stage vertical centrifugal pump. According to the structural characteristics of deep well pumps, the correct use and timely troubleshooting can ensure the safe operation of deep well pumps and prolong their service life. Stainless steel multi-stage deep well pump works description Stainless steel multi-stage deep well pump belongs to the technical field of a pump, mainly for deep well water. The pump body and the impeller are made of silica sol. The lost wax mold is precision and the casting material is stainless steel. Its structure includes pump body, impeller and shaft. Each stage consists of a pump body and an impeller. The impeller is contained in the pump body, the pump body and the impeller are respectively installed on the shaft, the pump body is matched with the shaft clearance, the impeller and the shaft are fixedly matched, and the pump bodies at all levels are sequentially assembled on the shaft. 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 at each level of the pump body and impeller can have about seven meters of lift, multi-level series will be able to meet some special needs. Its corrosion-resistant, long life, high precision machining, according to customer and market demand for production and assembly level.
