Description

High-efficient low discharge doublestage centrifugal pump

Technical Field

The utility model relates to a centrifugal pump technical field specifically is a high-efficient little flow doublestage centrifugal pump.

Background

The centrifugal pump is a pump for conveying liquid by means of centrifugal force generated when an impeller rotates, the impeller is a core part of the centrifugal pump, the rotating speed of the impeller is higher than the output force of the impeller, blades on the impeller play a main role, and the impeller passes through a static balance experiment before assembly. The inner and outer surfaces on the impeller are required to be smooth to reduce frictional losses from the water flow.

The existing centrifugal pump works by utilizing the rotation of an impeller to enable water to generate centrifugal motion, before a water pump is started, a pump shell and a water suction pipe are filled with water, then a motor is started, a pump shaft drives the impeller and the water to generate high-speed rotation motion, the water generates centrifugal motion, is thrown to the outer edge of the impeller and flows into a water pressing pipeline of the water pump through a flow channel of a volute-shaped pump shell;

but because the centrifugal pump must add water earlier when using, the staff need wait for the injection of water just can start the centrifugal pump, and need spend the time operation when adding water, lead to needing to wait for a period of time just can work when starting the centrifugal pump, inconvenient staff's use, the work efficiency of device has been reduced, simultaneously because the lift distance of centrifugal pump generally improves through the rotational speed of impeller, and the rotational speed upper limit of impeller is fixed, lead to the lift distance of centrifugal pump relatively poor, the result of use of device has been reduced.
