A self-protruding shaft end vane anti-cavitation mechanism

Abstract

The invention discloses an anti-cavitation mechanism for automatically protruding shaft end blades, which includes an end cover, an outer body, a chute A at one end of the end cover, a T-shaped sliding part and a sliding part arranged in the T-shaped sliding part. The blade; the T-shaped slider includes a vertically arranged axial connection part and a radial connection part. The axial connection part is connected to the bottom end of the chute A through the first elastic connection component; the radial connection part is provided with an opening facing outward The chute B in the direction, the blade is connected to the bottom end of the chute B through the second elastic connecting component; the outer casing is sleeved on the outside of the end cover, and the front end is equipped with a movable self-locking component, which is not affected by centrifugal force The T-slide is then provided with a thrust directed towards the end cap. The anti-cavitation mechanism installed at the pump inlet in the present invention can automatically eject the blades according to the working depth of the liquid surface of the pump, and the ejected blades rotate synchronously with the main shaft of the pump to provide pressure for the pump inlet to prevent cavitation and consume energy. Low, energy saving and environmental protection.

Description

technical field [0001] The invention belongs to the field of fluid machinery, in particular to an anti-cavitation mechanism for automatically protruding shaft end blades. Background technique [0002] When the submersible pump is working, as the water level continues to drop, the inlet pressure of the pump continues to decrease, resulting in cavitation. If the inducer (or other booster impeller) is directly installed at the pump inlet, although it can effectively prevent the cavitation of the pump at low water level, if the cavitation does not occur in the high water level unit, the inducer (or other booster impeller) booster impeller) will bring additional unnecessary energy loss. Contents of the invention [0003] Aiming at the cavitation problem of the submersible pump in the prior art, the present invention proposes an automatic protruding shaft end vane anti-cavitation mechanism. [0004] Realize above-mentioned technical purpose, reach above-mentioned technical eff...
