Embodiment Construction

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] A composite ceramic impeller, such as figure 1 and figure 2 As shown, it includes a front cover 1, a rear cover 2 and several arc-shaped blades 3 arranged between the front cover 1 and the rear cover 2. The front cover The middle part of 1 is provided with an impeller suction port 4, and the inner wall of the impeller suction port 4 is provided with an annular suction port ring 5, and the suction port ring 5 includes a base part 5a and a wear-resistant part 5b connected with the b...

Abstract

The invention relates to the technical field of slurry pumps, and discloses a composite ceramic impeller which comprises a front cover plate, a rear cover plate and a plurality of arc-shaped blades, the front cover plate and the rear cover plate are oppositely arranged, the arc-shaped blades are arranged between the front cover plate and the rear cover plate, and an impeller suction inlet is formed in the middle of the front cover plate. An annular suction inlet ring is arranged on the inner wall of the impeller suction inlet, the suction inlet ring comprises a base body part and a wear-resisting part connected with the base body part, the base body part is connected with the front cover plate, the wear-resisting part is in a circular truncated cone shape on the opening side, and the wear-resisting part is connected with the wear-resisting part. The diameter of the end, away from the rear cover plate, of the wear-resisting part is larger than that of the end, close to the rear cover plate, of the wear-resisting part. The service life of the impeller can be prolonged.

Description

technical field [0001] The invention relates to the technical field of slurry pumps, in particular to a composite ceramic impeller and a production process thereof. Background technique [0002] A slurry pump refers to a machine that increases the energy of a solid-liquid mixed medium through the action of centrifugal force (rotation of the impeller of the pump), and converts electrical energy into kinetic energy and potential energy of the medium. Mainly applicable to: mines, power plants, dredging, metallurgy, chemicals, building materials and petroleum industries. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy, leaving the outer edge of the impeller at high speed and entering the volute pump casing; in the volute pump casing, the liquid decelerates due to the gradual expansion of the flow channel, and will Part of the kinetic energy is converted into static pressure energy, and finally flows ...
