Embodiment 1

[0061] like figure 1 , 2 , 3, Embodiment 1 of the present invention is a wear-resistant pump body of a medium-sized pump. The wear-resistant pump body includes a metal shell and a ceramic lining, wherein the metal shell includes a front shell 001 and a rear shell 005, and the water inlet 008 is arranged at On the front shell 001, the front shell 001 and the rear shell 005 are buckled on a plane A-A passing through the water outlet and connected together by bolts 009. The ceramic lining includes 12 pieces of different shapes arranged on the axial side of the wear-resistant pump body, sequentially The combined curved plate 003 also includes a fan-shaped front annular plate 0041 arranged on the side of the feed port of the wear-resistant pump body and a rear annular plate 0042 arranged on the other side. The front annular plate and the rear annular plate are respectively made of 6 fan-shaped boards are put together; such as image 3 Shown is a schematic diagram of the rear rin...

Embodiment 2

[0063] like Figure 4 As shown, Embodiment 2 of the present invention is a three-dimensional view after the curved panels of a large wear-resistant pump body are assembled, including 40 curved panels 003 of silicon nitride and silicon carbide, and the working surface area of ​​a single curved panel is 0.1- 0.15 square meters, the axial projection angle of a single curved panel is 15°-20°, and the inner contour of all the curved panels 003 is two circles.

Embodiment 3

[0065] Embodiment 3 of the present invention is a medium-sized wear-resistant pump body, Figure 5 Shown is one of the curved panels 003, a plane 0032 coincident with the A-A plane is provided on the curved panel 003, and a protruding lip 0031 extending outward along the A-A plane is also provided to enhance the wear resistance of the place. The area of ​​the curved panel is 0.13m 2 , the axial projection angle α is 62°.

Abstract

The invention discloses a wear-resistant pump body and a manufacturing method thereof. The wear-resistant pump body comprises a shell and a lining arranged on the inner side of the shell, wherein a water inlet is formed in one side of the shell, the shell is provided with an A-A plane and a water outlet, the shell comprises a front shell and a rear shell which are detachably connected along the A-A plane, the lining comprises a plurality of curved plates which can be spliced in sequence, the lining further comprises a front annular plate arranged on one side close to the water inlet and a rearannular plate arranged on the other side, and a buffer wear-resistant layer is further arranged between the shell and the lining. The wear-resistant pump body has the advantages that the manufacturing cost of a wear-resistant pump can be remarkably reduced by selecting a reasonable splicing mode of a ceramic lining and the reasonable shape and boundary dimension of the curved plates, the coarse particle scouring resistance of the wear-resistant pump body is improved, the service life of the pump body is prolonged, the reliability of the pump body is improved, and the large-scale production iseasy to realize.

Description

technical field [0001] The invention relates to rotary power pump equipment, in particular to a wear-resistant pump body and a manufacturing method thereof. Background technique [0002] In industries such as mineral processing and smelting, centrifugal pumps are often used to transport some abrasive solid-liquid two-phase flows, and wear-resistant pumps are often used. The flow parts of the wear-resistant pump are severely worn, and the wear-resistant pump body is one of the most worn parts. In order to improve the life of the wear-resistant pump, the pump body must be made of wear-resistant materials. The most commonly used wear-resistant materials are wear-resistant Alloy and rubber, but the properties of these two wear-resistant materials often cannot meet the requirements of many working conditions. [0003] In recent years, some technologies of using ceramic materials to manufacture wear-resistant pump bodies have been disclosed, such as CN108425850A. This technology ...
