Since the balance multistage pump automatic balance principle

Self balancing multistage pump automatic balance principle

self balancing multistage pump due to the impeller and symmetrical layout, produced in the operation of the axial force to get the phase equilibrium, which does not need to balance device, make the wear and tear of axial load and minimize the adverse effects of disturbance to the system. Because the passage parts such as impeller and guide blade in manufacturing, port geometry and dimensional accuracy and relative position precision and design there is a deviation, the size and direction of inevitable uncertainty of residual axial force, this part of the residual thrust bearing axial force. shaft is always in a state of tension, the stress of the shaft evenly, so as to improve the rigidity and critical speed of the water pump rotor, significantly improve the stability and reliability of the pump.

since the balance of multistage pumps, pump industry production from the production plan arrangement, special operating mode of water pump configuration scheme, raw materials into the factory, casting, machining parts, assembly, pressure test components static 圧 test, performance testing, factory inspection each working procedure, such as operating strictly according to quality management procedures, cengcengbaguan, procedure, is responsible for the next working procedure, the unqualified parts don't care, don't accept, don't use, not qualified products factory; Ensure that the factory qualified rate reached 100%.

It is beyond doubt that benefits winter cover pump. Market sentiments are strong, especially in the light of growing pool cover drain pump observed globally.
As manufacturers we are determined to be the very best in submersible pump, regardless of the size, pedigree or inclinations of our competitors.
