Description

QJ stainless steel series deep well pump belongs to the electric pump with high-performance wear-resistant electric pump. As the current highest quality deep well pump at home and abroad, the power parts are equipped with a submersible stainless steel motor produced by the current most advanced technology. And It has absolutely no any pollution to water quality. Adopting high quality stainless steel shell, shaft core, coupling, water inlet and pump head (or copper alloy water inlet, pump head), high-strength wear-resistant new composite polymer impeller and stainless steel diversion shell, the new "floating type"  structure impeller has no any axial pressure to the motor during operation. Especially suitable for industry and mining, agriculture, construction, aquaculture, food and beverage industry and family (or high-rise water use).

Working Conditions

1. Three-phase AC power supply with power frequency of 50Hz and rated voltage of 380v or 660v (tolerance ±5%).

2. The content of solid particles(by mass) is not more than 0.01%.

3. The acidity PH value of the pumped liquid is 6.5-8.5.

4. Temperature of the conveying medium does not exceed 100℃.

5. The inlet of the pump must below the dynamic water level 1m, but the diving depth should not exceed the static water level by 70m, and the bottom of the electric pump must be at least 1m deep from the bottom.

6. The well is required to be upright, the well wall is smooth, and the well pipes must not be staggered.

Structure Features

1. Simple structure, high efficiency units, low noise, safe and stable operation, and convenient installation and maintenance.

2. QJ series of submersible electric well pumps are composed of submersible three-phase asynchronous motors and water pumps. The motor is directly connected to the upper pump body, and the upper end of the motor shaft is equipped with a reliable shaft sealing device, which can effectively prevent the exchange between the coolant in the motor and the pumped medium, and ensure the long-term safe and stable operation of the water pump.

3. The submersible pump is a kind of single-suction multi- stage vertical centrifugal pump, and the submersible motor is a water-filled wet, submersible asynchronous motor for vertical wells. The motor and the water pump are directly connected through a barrel coupling.

4. The motor winding is nylon sheathed polyethylene water-resistant electromagnetic wire. It is only to fill the motor cavity with clean water.

5. The motor guide bearing adopts water lubricated bearing. The lower part of the motor doesn’t has a thrust bearing that bear the up and down axial force of the pump. The thrust bearing of high head water pump adopts nickel-containing copper sector blocks, and the imported Phillips slide plate is used for grinding, which can bear the up and down axial force of the pump.

6. The deep well submersible pump is equipped with an axial load bearing device between the pump and the motor, and the head can be increased to 900m.
