Vertical multistage centrifugal pump working principle

Knowledge

The working principle of haina brand vertical multistage centrifugal pump is a centrifugal pump on the effect of rotating impeller on the liquid of the prime mover mechanical energy transmitted to the liquid.As a result of the action of vertical multistage centrifugal pump in the process of the liquid flowing from impeller import export, its speed can be increased, and pressure can be impeller discharge of liquid through the pressure out of the room, most of the speed can be converted to pressure, and then along the discharge pipe to go out, at this point, the impeller inlet vacuum or low pres […]

Multistage pump structure

Knowledge

The basic construction of multistage pump is composed of six parts, respectively, impeller, pump body, pump shaft, bearing, seal ring, stuffing box. 1, the impeller is the core part of the multistage pump, its speed is higher than strength, on the impeller blades and play a major role, the impeller through static balancing experiments before assembly.Impeller on the inside and outside for smooth surface to reduce friction loss of water. 2, the pump body also calls the pump shell, it is the body of the multistage pump.Support fixed effect, and connected to install bearing bracket. 3, the role o […]
