The vertical centrifugal water pump relies on the action of the rotating impeller on the liquid to transfer the mechanical energy of the prime mover to the liquid. Due to the action of the centrifugal pump, when the liquid flows from the impeller inlet to the outlet, its velocity energy and pressure energy are both increased. The liquid discharged by the impeller passes through the extrusion chamber, and most of the velocity energy is converted into pressure energy, and then transported along the discharge pipeline. At this time, a vacuum or low pressure is formed at the inlet of the impeller due to the discharge of liquid, and the liquid in the suction pool is pressed into the inlet of the impeller under the action of liquid surface pressure/atmospheric pressure, so the rotating impeller continuously Suction and discharge of liquid.

Vertical centrifugal water pump structural features:
1. The vertical centrifugal water pump is a 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. It has a compact and beautiful appearance, a small footprint and low construction investment.
2. The impeller is directly installed on the extended shaft of the motor. The axial dimension is short and the structure is compact. The pump and motor bearings are arranged reasonably, which can effectively stabilize the radial and axial loads generated by the pump operation, thereby 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 hard alloy material, wear-resistant seal, which can effectively prolong the service life of the mechanical seal.
4. The vertical centrifugal water pump is easy to install and maintain, without dismantling the piping system.
