200m3/h 40m 12 Inch 37kw 50hp 3 Phase 380v Farm Irrigation Industrial Clean Water Vertical Electric Submersible Pump
QJ type well submersible pump is designed according to the national standard of energy saving products, mainly used to extract groundwater from deep Wells, but also widely used in farmland irrigation, urban, industrial and mining enterprises drainage and highland, mountainous areas of human and animal water and high-rise buildings and other pressurized water supply.
This type of pump is composed of QJ type submersible pump and YQS type submersible motor to work underwater; It has the advantages of compact structure, small volume, low noise, no secondary pollution, convenient installation, use and maintenance, safe and reliable operation, high efficiency and energy saving, and does not need to build the pump house. It can be used for vertical and horizontal installation, and can also be used for open water and ground pumps. Compared with other ground water supply and drainage pumps, it has the advantages of small space occupation, no pollution and leakage, convenient installation and use
The motor is a closed wet structure filled with water. The stator winding of the motor is a multi-layer electromagnetic wire with water-resistant polyethylene insulation and nylon sheath. Guide bearings and thrust bearings are made of water lubricated material. The motor is filled with clean water to cool the motor and lubricate the bearings. The pressure regulating film (made of rubber) is installed at the bottom of the motor to adjust the expansion and contraction pressure difference of the clean water in the body caused by the temperature rise of the motor. The upper shaft of the motor is equipped with a sand prevention mechanism to prevent water sediment from entering the body.
How to choose a suitable water submersible pump types, the most important steps for submersible pump running well:
