Manufacturing and assembling process of a submersible axial flow pump

Many advanced technology are used in the manufacture of the submersible axial flow pump.

1, the submersible axial flow pump impeller is designed by advanced hydraulic model. The dynamic balance of the impeller is balanced by the Shanghai Shen Guang balance test machine, so that the dynamic balancing accuracy reaches G6.3 level, so as to ensure smooth operation of the pump, no vibration and running noise is less than 70 dB.

2. The induction line of the submersible axial flow pump adopts special processing. Submersible axial flow pump operation under water, long-term poor working conditions, and other man-made unfavorable factors, the cable will accidental damage to the motor inlet, the cable through the special processing after vulcanization sealing eliminates cable breakage and damage to the pump problems, the main principle is: electric submersible cable is composed of rubber outer wrapping, filling and in the cable core, each cable core is composed by rubber wrapping and multi strand copper wire cable, cable or cable when the wrapper in the foreskin is damaged, water will follow the clearance of copper wire cable core and the outer wrapping of the gap in the inner core or cable between the motor into the cavity thus, burning motor, our company according to the above phenomena, the single core cable after peeling tin treatment after implantation of rubber, and then finally the single core cable with rubber ring seal rubber, vulcanized rubber with water After a dense cable, the motor can dive into the water 20 meters and work normally. It fundamentally eliminates the way water enters the motor, and the relevant drawings are described in detail.

3, the assembly of submersible axial pump, rotor shaft and bearing adopts hot pressing assembly. Main components and key components are processed in CNC machining center, quality control is carried out on line, performance test is carried out in quality inspection center.

4, submersible axial flow pump casting using advanced mold manufacturing technology, the Ashland core system and three-dimensional space size precision, hydraulic components and parts of the blade passage with smooth surface, high hydraulic efficiency, so the parts in the manufacturing process meets the design requirements.
