QJ series Wells with submersible electric pump is mainly used in deep Wells to extract groundwater, but also widely used in farmland irrigation, urban, industrial and mining enterprises water supply and drainage, plateau, mountain water and high-rise buildings such as pressurized water supply. Its main feature is that the series of pump host by QJ (R) type submersible pump and YQS type submersible motor composed of a body to dive underwater work. 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, no need to build pump room and so on.
QJ series submersible pumps are specially designed and can also be used in open water and as surface pumps. They can be installed and used vertically and horizontally. Compared with other ground water supply and drainage pump, it has the advantages of small occupation space, no pollution and leakage, easy installation and use. Can be used for residential and high-rise, villa water supply and other fields.
QJR series well water submersible pump adopts special material and structure, which can be used to extract underground hot water.
Power supply: three-phase AC, voltage 380V/660V, frequency: 50HZ
Water source:
Water temperature :QJ type W20°C/QJR type 20~100°C
Total content of solid impurities in water (weight ratio) shall not exceed 0.01%
Chloride ion content shall not exceed 400mg/L
The PH value is 6.5 to 8.5
Submersible pump into the water depth is not more than 70m
The above conditions are the basic use conditions, such as use conditions beyond the above range, special production is needed to ensure the normal operation of the pump
Type QJ submersible pump consists of multistage centrifugal impeller in series. The pump stages are connected by flat tension bars or bolts, and there is a rubber (or copper) shaft support between each section. The top of the pump is provided with a check body (high head).YQS submersible motor is a closed water-filled three-phase asynchronous motor with water-resistant polyethylene insulated and nylon sheathing multi-layer winding wires. Guide bearings and thrust bearings are water-lubricated bearings; The upper part of the motor is equipped with a sand control mechanism to prevent sediment from entering the motor cavity.
