Rotation direction of vertical water pump blades

The impeller in direction B rotates well. The water flow in direction b is larger.

The impeller in the above picture is the impeller of centrifugal pump. Its working principle is that the centrifugal force generated by the high-speed rotation of the impeller after the water pump runs throws the water in the impeller channel around and presses it into the volute, and the inlet of the impeller forms a vacuum. The water in the pool is sucked along the suction pipe under the external atmospheric pressure to replenish the space. Then the sucked water is thrown out by the impeller and enters the outlet pipe through the volute.

It can be seen that if the impeller of centrifugal pump keeps rotating, it can continuously absorb and press water, and the water can continuously go from low to high or away.

Structural features:

1, single-stage vertical centrifugal pump is of vertical structure, with the same inlet and outlet diameters and located on the same center line. It can be installed in the pipeline like a valve, with compact and beautiful appearance, small floor space and low construction investment.

2. The impeller is directly installed on the extension shaft of the motor, with short axial dimension, compact structure and reasonable configuration of the pump and motor bearings, which can effectively stabilize the radial and axial loads generated by the operation of the pump, thus ensuring the smooth operation of the pump, small vibration and low noise.

3. The shaft seal adopts mechanical seal or mechanical seal combination, adopts imported titanium alloy sealing ring, medium-sized high-temperature resistant mechanical seal and adopts cemented carbide material, which can effectively prolong the service life of mechanical seal.

4, easy installation and maintenance, no need to dismantle the pipeline system.
