AI Technical Summary
Existing slurry pumps are susceptible to erosion and cavitation wear when transporting media containing solid particles, resulting in a short service life. Due to the acidity and alkalinity of the medium, the pump parts are prone to corrosion, further shortening the service cycle.
The design is combined with wear-resistant ceramic lining and wear-resistant coating. The ceramic lining forms a solid anti-wear layer on the turtle mesh and guard plate. The paint enters the space of the turtle mesh through the through holes, enhancing connectivity and overall strength and extending service life.
It significantly improves the wear resistance and service life of the slurry pump. After the paint and turtle mesh are worn, it can be reused by replacement or maintenance, without the need for overall replacement, reducing the cost of use.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of slurry pumps, in particular to a super wear-resistant ceramic slurry pump. Background Art
[0002] At present, the slurry pump is a centrifugal pump used to transport and process solid-liquid two-phase or multi-phase materials. It is widely used in mining, nonferrous metals, metallurgy, coal, petroleum and chemical industries. Because the medium transported by the slurry pump mostly contains a lot of solid particles, and sometimes it is even slurry. The fluid containing solid particles causes erosion and wear (particle wear and cavitation wear) to the slurry pump during the transportation process, which becomes the main reason for the short service life of its flow parts. In addition, most of the transported fluid media have varying degrees of acidity and alkalinity, which have a greater corrosive effect on the slurry pump, greatly shortening its service life. Therefore, in addition to the requirements for the usual technical parameters such as flow rate and head, this type of centrifugal pump also has higher requirements for wear resistance, cavitation resistance and corrosion resistance; the flow parts of the slurry pump are impellers, volutes, and guard plates;
[0003] Some existing slurry pumps are cast with Cr26 material. Due to the general wear resistance of Cr26, the service life of the slurry pump is short. If all the flow-through parts are made of ceramic, the cost is much higher than that of metal materials. After wear, they need to be replaced as a whole, resulting in high cost and inconvenience in use.
[0004] Therefore, a super wear-resistant ceramic slurry pump is proposed. Utility Model Content

The wear-resistant coating has the advantages of high strength, high wear resistance, and fast curing speed, and can be tightly combined with the turtle-shaped net.

The wear-resistant coating can enter the space of the adjacent turtle-shaped net through the through hole, and can improve the connectivity of the wear-resistant coating in the adjacent turtle-shaped nets, improve the overall strength, and further enhance the wear resistance of the slurry pump through the wear-resistant ceramic lining.
