Problems solved by technology

Due to structural design defects of the existing mortar pumps, the mechanical seal device generally leaks under negative pressure conditions; in addition, with the extension of the pump running time, the installation and coordination of the impeller and other parts, especially the root of the impeller, will also be damaged. Leakage will occur, affecting the service life of the mortar pump

Abstract

The invention discloses a holding plate decay-resistant and wear-resistant slurry pump which comprises a pump body (1), a pump cover (2), a shaft (3), a sealing box (4), a vane wheel (5) and a mechanical sealing device; the mechanical sealing device consists of a moving ring (6), a static ring (7), a static ring seat (8), a spring (9) and a spring seat (10); the spring seat (10) is positioned with two dummy clubs of the static ring seat (8) by two seams (11) at one end; the static ring (7) is positioned with two dummy clubs (12) at the other end of the spring seat (10) by the two seams on the static ring (7) ; the moving ring (6) is positioned with the vane wheel (5) by the seams on the moving ring (6); the friction surface of the moving ring (6) contacts the friction surface of the static ring (7). The structure adopted by the invention prolongs the service life of the slurry pump due to being capable of improving leak prevention performance.

Description

technical field [0001] The invention relates to a liquid conveying device, in particular to a splint type corrosion-resistant and wear-resistant mortar pump. Background technique [0002] Mortar pump is a kind of liquid conveying equipment, mainly composed of pump body, shaft, impeller and mechanical seal device. At present, mortar pumps are widely used in various industries, such as conveying acid, alkaline clear liquid or slurry, various corrosive pulps in the metallurgical industry, and various sewage in the environmental protection industry. The mortar pump not only requires strong corrosion resistance, but also But also requires good sealing performance. Due to structural design defects of existing mortar pumps, the mechanical seal device generally leaks under negative pressure conditions; in addition, with the extension of the pump running time, the installation and coordination of the impeller and other parts, especially the root of the impeller, is also damaged. Le...
