What is the water pump population pre rotation, what harm?
Is the entrance of water flow in the formation of complex turbulent flow, flow direction, shock, vibration, easy to damage the front entrance device, such as vane impeller, shaft sleeve, sealing element. In order to prevent the emergence of the pre swirl phenomenon, usually the design will inlet than outlet diameter, try to make the entrance flow in laminar flow, according to streamline our design, in order to protect the safety and prolong the service life of equipment.
Is the entrance of water flow in the formation of complex turbulent flow, flow direction, shock, vibration, easy to damage the front entrance device, such as vane impeller, shaft sleeve, sealing element.
The turbulence formation flow entrance, the flow direction is complex, impact, vibration, easy to damage the device before; if there is no water pump entrance pre swirl design will affect the safety and service life of equipment.
