Problems solved by technology

In order to reduce the wear of the pump casing by solid particles in the medium, the ordinary centrifugal pump needs to be cast with wear-resistant materials or surfacing welding wear-resistant hard alloy materials. It is difficult to realize in technology; in addition, the ordinary centrifugal pump needs to be installed in the pump casing so that the axis of the volute outlet of the ordinary centrifugal pump is parallel to the axis of the discharge port of the pump casing to ensure that the solid particles in the medium will not Cause secondary wear on the inner wall of the pump casing. In the actual installation process, it is not easy to install the ordinary centrifugal pump in the casing through the installation port, and the volute outlet axis of the ordinary centrifugal pump is easy to deflect. The solid particles in the medium output from the outlet of the volute will still cause wear to the inner wall of the pump casing

Embodiment Construction

[0024] Below in conjunction with embodiment technical solution of the present invention is made more specific description:

[0025] The present invention includes a pressure-resistant pump casing 10, which is provided with a feed port 11, a feed port 11, and an installation port. A pump cover 13 is installed at the installation port. The high-pressure wear-resistant pump also includes The centrifugal impeller 20 and the guide vane diffuser 30 installed in the pressure-resistant pump casing 10 through the installation port, the medium reaches the centrifugal impeller 20 through the feed port 11 and then passes through the guide vane diffuser 30 is decelerated and pressurized and transported to the discharge port 12. The centrifugal impeller 20 and guide vane diffuser 30 are all made of wear-resistant materials. The pump cover 13 is fixed to the pump casing 10 by bolts. The guide vane diffuser 30 used in the present invention is aimed at the characteristics of high pressure med...

Abstract

The invention relates to a detachable high pressure abrasion-resistant pump for conveying media containing solid particles. The detachable high pressure abrasion-resistant pump comprises a pressure-resistant pump shell which is provided with a feeding port, a discharging port and an installing port; and a pump cover is installed at the position of the installing port. The high pressure abrasion-resistant pump further comprises a centrifugal impeller installed in the pressure-resistant pump shell through the installing port, and a guide vane pressure expander; the media reach the centrifugal impeller through the feeding port, then are subjected to speed decreasing pressurization through the guide vane pressure expander and are conveyed to the discharging port; and the centrifugal impeller and the guide vane pressure expander are both made from an abrasion-resistant material. According to the detachable high pressure abrasion-resistant pump, the guide vane pressure expander separates the pressure expanding function of the pump shell from the pressure bearing function of the pump shell by means of the characteristics that the media are high in pressure and contain the solid particles, and the pressure expanding function is borne by the guide vane pressure expander; and after being subjected to pressure expanding through the guide vane pressure expander, high speed liquid flow enters a flow channel where the discharging port of the pump shell is located, the flowing speed is decreased, scouring on the inner wall of the pump shell is not caused any more, and therefore the pump shell only bears the pressure bearing function. The detachable high pressure abrasion-resistant pump is convenient to install and detach and low in casting cost, the maintaining cost is reduced, and the equipment running reliability is improved.

Description

technical field [0001] The invention belongs to the field of centrifugal pumps, in particular to a detachable high-pressure wear-resistant pump used for transporting media containing solid particles. Background technique [0002] Existing pumps used for conveying media containing solid particles usually include a pump casing and an ordinary centrifugal pump installed in the pump casing. The pump casing is provided with an inlet, an outlet, and a Ordinary centrifugal pump installation port. In order to reduce the wear of the pump casing by solid particles in the medium, the ordinary centrifugal pump needs to be cast with wear-resistant materials or surfacing welding wear-resistant hard alloy materials. It is difficult to realize in technology; in addition, the ordinary centrifugal pump needs to be installed in the pump casing so that the axis of the volute outlet of the ordinary centrifugal pump is parallel to the axis of the discharge port of the pump casing to ensure that ...
