How to use the coaxial submersible pump?

The coaxial submersible pump is the impeller of the submersible pump directly mounted on the shaft extension end of the motor and integrated with the pump. Its characteristics are compact structure, convenient installation, no pump room, small footprint, long-distance control operation, safety and reliability, simple maintenance, and short and thick submersible pumps. Can be used for drainage rescue, surface drain drainage, urban drainage, agricultural drainage and irrigation.

Conditions of Use

1. The motor must be filled with clean water or other formulated aqueous solutions.

2. The submersible pump should completely submerge in water.

3. The water temperature is not higher than 20°C.

4. The solid impurity content in water does not exceed 0.01%.

5. The water does not contain chemically corrosive substances and the pH is between 6.5-8.5.

System components: The coaxial submersible pump consists of submersible motors, submersible pumps, power cables, signal cables, joint materials, gate valves, check valves, and elbows.

Submersible motor: It is a water-filled wet seal structure. It is generally a vertical installation.

1. According to the use situation, some cases have radiating ribs and water channels, and are equipped with suction caps to facilitate electrode cooling.

2. The bottom of the motor is equipped with elastic capsules, which can automatically adjust and balance the pressure inside and outside the motor.

3. The motor adopts the mechanical seal box rubber oil seal, and the rubber and “O” ring and sealant are used on the matching surface of the mouth, which has good sealing performance.

4. The motor guide bearing and thrust bearing are all made of high-quality, high-strength, wear-resistant materials. They have good wear resistance and high axial load.

Submersible pumps: Most of them are single-stage impellers, and they are installed directly on the deep extremity of the motor shaft. The impeller and the guide shell are made of high-strength cast iron that can resist wear. Alloys or coated wear-resistant materials can also be used according to different requirements.

Control cabinet: Short circuit, overload protection, voltage protection and water level monitoring device and temperature protection device can be installed as required.

Cable: Use waterproof three-core rubber flexible cable, its length is 5 meters or as required.
