Description

Prevent blockking up and prevent suck-back axial-flow pump

Technical Field

The utility model relates to an inhale axial-flow pump technical field specifically is an prevent blockking up and prevent suck-back axial-flow pump.

Background

The axial flow pump is a pump for conveying liquid in the axial direction by the action force of the blades of the rotating impeller on the liquid, and there are vertical, horizontal, inclined and through-flow pumps. An axial flow pump impeller is provided with 2 to 7 blades and rotates within a circular tube shaped pump housing. The pump casing on the upper part of the impeller is provided with fixed guide vanes for eliminating the rotation motion of the liquid, converting the rotation motion into axial motion and converting the kinetic energy of the rotation motion into pressure energy. Axial pumps are usually single stage, with a few being made as two stages. The flow range is large, the axial flow pump is generally vertical, the impeller is immersed under water, and the axial flow pump is horizontal or inclined. When the impeller of the small axial-flow pump is mounted at a high water outlet surface, a vacuum pump is required to exhaust and guide water to start.

When the existing axial flow pump is started, the axial flow pump pumps liquid, and once the axial flow pump is stopped or suspended, water entering a water pipe flows backwards, so that waste is caused. Especially, the piping is long, where the water flow is large, the waste is greater. In the process of water absorption, light floating objects such as leaves and the like are easily adsorbed on the filter screen, so that the filter screen is blocked, and the condition that the axial flow pump absorbs water unsmoothly or even idles is caused. Therefore, the anti-blocking and anti-suck-back axial flow pump is provided.
