Abstract

The utility model discloses a guard plate structure for improving efficiency of a slurry pump, which relates to the technical field of slurry pumps and comprises a pump body, wherein impellers are rotatably connected in the pump body, a rear guard plate and a front guard plate are arranged on two sides of the impellers and positioned on the inner wall of the pump body, blades are arranged on the rear guard plate and the front guard plate, and the rear guard plate and the front guard plate are connected through a sheath. The sheath is connected with the inner wall of the pump body through a sheath sealing gasket. Through transferring the blade on the impeller to backplate (front backplate, backplate), effectively prevent slurry particles to get into between impeller and backplate (front backplate, backplate) clearance, backplate non-rotator effectively provides pump life simultaneously.

Description

Guard plate structure for improving efficiency of slurry pump

Technical Field

The utility model relates to the technical field of slurry pumps, in particular to a guard plate structure for improving the efficiency of a slurry pump.

Background

The slurry pump is a centrifugal pump in terms of its operation principle, and conceptually means a device for converting electric energy into kinetic energy and potential energy of a medium by a mechanism that increases the energy of a solid-liquid mixed medium by centrifugal force (rotation of an impeller of the pump). Is mainly applicable to the fields of industries such as mines, power plants, dredging, metallurgy, chemical industry, building materials, petroleum and the like.

When the slurry pump normally operates, when the slurry pump conveys more slurry of particles, part of slurry is thrown out by the impeller to flow back between the impeller and the gaps of the guard plates (front guard plate and rear guard plate), the slurry flows back between the front guard plate and the impeller, so that slurry at the suction inlet of the pump is mixed, the service performance is influenced, the slurry flows back simultaneously, a large amount of slurry particles are positioned between the impeller and the gaps of the guard plates (front guard plate and rear guard plate), and abrasion is serious.

As shown in fig. 1: the auxiliary blades are added on the front cover plate and the rear cover plate of the impeller, so that slurry particles are effectively prevented from entering a gap between the impeller and a guard plate (a front guard plate and a rear guard plate); however, the impeller is provided with auxiliary blades, so that the weight of the rotating body of the pump is increased, and the efficiency of the pump is reduced. Therefore, relates to a guard plate structure for improving the efficiency of a slurry pump.

Disclosure of utility model

The utility model aims to provide a guard plate structure for improving the efficiency of a slurry pump, which solves the following technical problems: the impeller is provided with auxiliary blades, so that the weight of the rotating body of the pump is improved, and the efficiency of the pump is reduced.

The aim of the utility model can be achieved by the following technical scheme:

The utility model provides an improve sediment stuff pump efficiency backplate structure, includes the pump body, the inside rotation of the pump body is connected with the impeller, backplate and front guard plate are installed to the both sides of impeller and be located on the inner wall of the pump body, all install the blade on backplate and the front guard plate, connect through the sheath between backplate and the front guard plate.

As a further scheme of the utility model: the sheath is connected with the inner wall of the pump body through a sheath sealing gasket.

As a further scheme of the utility model: and a pump cover is arranged outside the pump body.

As a further scheme of the utility model: the motor pump further comprises a bracket, wherein the inside of the bracket is rotationally connected with a shaft, one end of the shaft extends into the pump body to be connected with the impeller, the shaft is sealed with the pump cover through a shaft seal component, and the shaft is driven by the motor.

The utility model has the beneficial effects that:

through transferring the blade on the impeller to backplate (front backplate, backplate), effectively prevent slurry particles to get into between impeller and backplate (front backplate, backplate) clearance, backplate non-rotator effectively provides pump life simultaneously.
