Vortex elimination type impeller and centrifugal pump thereof

Abstract

The invention belongs to the technical field of centrifugal pumps, and particularly relates to a vortex elimination type impeller and a centrifugal pump thereof. The impeller comprises an impeller base, blades and rotation modules; the blades are arranged on the upper surface of the impeller base, first grooves are formed in the upper side faces of the blades, second grooves are formed in the lower side faces of the blades, swing grooves are formed over the blades, and the rotating modules are arranged in the swing grooves, and are used for eliminating vortex generated on the blades. The rotating modules are arranged, a first protection plate and a second protection plate are arranged on each rotating module, and are used for weakening the erosion of the bubbles on the blades, and eliminating the vortex on the blades, the erosion of the bubbles on the blades can be reduced, buffer modules are arranged and prevent the erosion from impacting the swing grooves, the service life of the blades can be prolonged, meanwhile, rotating wheels make tight contact with the buffer modules, the seal property of the buffer modules is improved, and detaching modules are arranged, detaching and replacing of the buffer modules on the blades can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of centrifugal pumps, in particular to a vortex elimination type impeller and a centrifugal pump thereof. Background technique [0002] As a typical vane-type fluid machine, the centrifugal pump works on the principle that the prime mover drives the impeller to rotate to do work on the fluid, converting the mechanical energy into the kinetic energy and pressure energy of the fluid, so as to realize the transportation of the fluid. The impeller of the centrifugal pump is inevitably accompanied by energy loss during the work process. [0003] A centrifugal pump is provided with an impeller on a protruding shaft, and the fluid in the volute is sent out by rotating the impeller. When the impeller rotates, a pushing force acts on water in the advancing direction of the blades of the impeller, so the local pressure becomes high, and on the other hand, a traction force acts on the water on the back side of the bla...

Problems solved by technology

[0005] In order to make up for the deficiencies in the prior art, the present invention proposes a vortex elimination impeller, which is used to solve the problem that air bubbles will be formed on the blade from the low-pressure area to the high-pressure area, and the formed air bubbles will impact and vibrate the blade, and the blade is long-term. Over time, the air bubbles generated will cause wear and damage to the blades
