Pump industry suppliers to tell you: since the balance of the principle of multistage pump and outstanding performance

self balancing principle and outstanding performance of multi-stage water pump

a, the working principle of

since the balance of multistage pump shaft under the drive of motor rotation, the liquid work, allow it to increase energy, so that the needed quantity of liquid pool by inhaling through the inlet section of the pump, the impeller, guide vane, the middle, the water level of outlet, the transition pipe, secondary inlet, the impeller, anti-missile leaf, water vertical outlet, the liquid flowing out.

multistage pump is single suction and double suction inlet of horizontal sectional multi-stage pump, pump suction can be vertical or horizontal, outlet vertical layout. When the seal ring and the degree of wear of guide vane set has influence on the performance of the pump work should be timely to replace, shaft seal form has two kinds of mechanical seals and packing seal. using packing seal, the location of the packing ring placed to the right, the tightness of packing must be appropriate, with liquid can drip seeps advisable. Loading pump seal element in a sealed cavity, cavity access to certain pressure of water, the water seal, water, and water lubrication. This series of multistage pump coupling with elastic dowel pin or diaphragm coupling driven directly by the prime mover. From the direction of the prime mover, pump is clockwise. Multistage pump can not remove the inlet and outlet piping change under the condition of bearing, seal.

the outstanding performance of multistage pump:

1, the new structure, with a symmetrical arrangement of impeller rotor parts, various symmetric impeller axial force generated by the offset each other, without the balance disk structure can realize the pump cavity large axial thrust of automatic balancing, break through the traditional structure of multistage pump;

2, high reliability, symmetrical arrangement of the impeller, the operation of the axial thrust is largely from phase equilibrium, thus does not require small gap, high pressure drop, easy to wash, easy to wear, easy to fail the balance disc device, the axial force of load on the wear of the pump and minimize the adverse effects of disturbance to the system. Residual axial force by the thrust bearing, remain the state of tension that makes the pump shaft, the shaft of the uniform stress state, the peak stress and the prototype structure is greatly reduced, so as to improve the rigidity and critical speed of the pump rotor, rotor pump running stability and reliability of the improved significantly.
