Application of coaxial deep well pump

Application of coaxial deep well pump
     Coaxial deep well pump is submersible pump impeller directly mounted on the motor shaft extension, machine pump. It is characterized by compact structure, easy installation, no pump room, small footprint, can achieve long-distance control operation, safe, reliable, simple maintenance, submersible pump volume is short and thick. Can be used for drainage and rescue, surface drainage drainage, urban drainage, agricultural drainage and irrigation. In this case,
Conditions of Use
1. The motor must be filled with clean water or other regulated aqueous solution.
2. The deep well pump should be completely submerged into the water work.
3. Water temperature is not higher than 20 ℃.
4. Solid impurities in water content of not more than 0.01%.
5. The water does not contain chemical corrosive substances, PH value between 6.5-8.5.
System components: coaxial submersible pump submersible motor, deep well pump, power cable, signal cable, joint materials, gate valve, check valve, elbow and other components.
Submersible motor: wet water seal structure, usually vertical installation.
1. According to the use of some chassis with cooling ribs and waterways, and equipped with suction hood to facilitate the electrode cooling. In this case,
2. Motor bottom with elastic capsule, can automatically adjust and balance the pressure inside and outside the motor.
3. Motor mechanical seal box rubber oil seal, with the mouth with a rubber "O" ring and sealant, has a good sealing performance.
4. Motor bearings and thrust bearings are selected high-quality high-strength wear-resistant materials, wear resistance, bearing high axial force.
Deep well pump: use single-stage impeller, directly mounted on the motor shaft deep extension, impeller and guide shell with wear-resistant high-strength cast iron, can also be used according to different requirements coated alloy or wear-resistant materials.
Control cabinet: with short circuit, overload protection, voltage protection and can be installed according to the requirements of water level monitoring devices, temperature protection devices.
Cable: Waterproof three-core rubber flexible cable, the length of 5 meters or on request
