Selection and use of coaxial submersible pump

Coaxial submersible pump is a submersible pump impeller directly installed in the shaft extension of the motor, the pump body. It is characterized by compact structure, convenient installation, no need of a pump room, small occupied area, can realize remote control operation, safe and reliable, easy maintenance, short volume submersible pump. Can be used for drainage and rescue, surface drainage, city drainage, agricultural irrigation and drainage.
Conditions of use
1 the motor must be filled with clean water or other water solution prepared according to the regulations.
2 submersible pump should be completely submerged in the work.
3 water temperature is not higher than 20.
4 the content of solid impurities in water is not more than 0.01%.
5 water does not contain chemical substances, pH value between 6.5-8.5.
The coaxial submersible pump is composed of submersible motor, submersible pump, power cable, signal cable, joint material, gate valve, check valve, elbow and so on.
Submersible motor: for the water filled wet seal structure, generally vertical installation.
1 in accordance with the use of the case, some of the housing with cooling ribs and waterways, and fitted with water absorption, to facilitate the heat sink.
2 motor at the bottom of the elastic capsule, can automatically adjust the balance of internal and external pressure motor.
3 the motor adopts the mechanical seal box rubber oil seal, the stop mouth with the rubber "O" - shaped ring and sealant, with good sealing performance.
4 motor guide bearing and thrust bearing are selected for high strength and high strength wear resistant materials, good wear resistance, high bearing capacity.
Submersible pump: more than a single impeller, directly installed in the shaft of the motor shaft, impeller and guide the shell using wear-resistant high strength cast iron, can also be used in different requirements of the alloy or coating wear-resistant materials.
Control cabinet: with short circuit, overload protection, voltage protection and can be installed in accordance with the requirements of the water level monitoring device, temperature protection device.
Cable: Waterproof three core rubber soft cable, the length of 5 meters or according to the requirements of custom.
