Section II: Manufacturing and Assembly Processes
Axial flow pump manufacturing employs numerousFrontierOur production techniques.
1The propeller of the submersible axial flow pump is designed with an advanced hydraulic model, and the dynamic balance of the propeller is achieved through balancing tests on a balancing machine, ensuring high precision in dynamic balance.G6.3Grade, ensuring the pump operates smoothly with no vibration and operating noise less than70Decibels. 
2The motor lead wires of the submerged axial flow pump are processed with special treatment. Due to the long-term operation of the submerged axial flow pump underwater under harsh conditions, coupled with other adverse human factors, the cables may suffer unexpected damage, leading to water entering the motor. The special sulfur vulcanization sealing process eliminates the隐患 of cable damage leading to pump failure. The main principle is as follows: the submerged cable consists of a rubber sheath, filler, and cable core. Each cable core is made up of an inner rubber sheath and multiple strands of copper wire. When the cable sheath or inner rubber sheath is damaged, medium water can enter the motor cavity through the gaps between the cable core and sheath or between the copper wires, thereby destroying the motor. In response to this phenomenon, our company peels the single-core cable, tin-plates it, and then implants it into the rubber. After that, the single-core cable is inserted into the rubber again and sealed with a rubber ring. By using sulfur vulcanized waterproof cables, the motor can be submerged underwater.20The rice mill operates normally, fundamentally eliminating pathways for water to enter the motor; see relevant drawings for details.
3The impeller shaft and bearings for submersible axial flow pumps are assembled using hot pressing technology. All major and critical components are processed in a CNC machining center, quality control is conducted on the assembly line, and performance testing is carried out at the quality testing center.
