QJ (R) deep well pump
I. Overview
QJ submersible pufmp for well is composed of multi-stage centrifugal impellers in series. It is a complete set of machines and tools for extracting groundwater from deep wells, and the conveying temperature is less than 20℃. It is widely used in farmland irrigation, water supply and drainage of industrial and mining enterprises and livestock water in plateau and mountainous areas.
QJR well hot water submersible pump, with special material and structure, is used for extracting underground hot water, and the conveying temperature is not more than 90℃. In addition, our company produces submersible pumps for seawater, mines and other special occasions according to users’ needs. The main engine of the pump is composed of QJ (R) submersible pump and YQS submersible electric pump unit. YQS submersible motor is a closed water-filled three-phase asynchronous motor, the winding adopts water-resistant continuous sealing structure, and the guide bearing and thrust bearing are all water-lubricated bearings; the upper part of the motor is equipped with a sand control mechanism to prevent sediment from entering the internal control of the motor. The submersible pump has the advantages of compact structure, small volume, light weight, convenient installation, use and maintenance, safe and reliable transportation, energy saving and so on.
