End face wear-resistant elastic composite rotor and elastomer production mold thereof

Abstract

The invention discloses an end face wear-resistant elastic composite rotor and an elastomer production mold thereof. The end face wear-resistant elastic composite rotor comprises a cam rotor pump, a support skeleton, an elastomer, special-shaped end face rings, a base, an upper base and a middle base; an elastomer rotor is arranged in a cavity body of the cam rotor pump; the support skeleton is provided with a plurality of skeleton blades, and skeleton grooves are formed in the end faces of the two ends of the support skeleton; the elastomer is arranged on the outer side of the support skeleton in a covering mode, gaps are formed in the end faces of the two ends of the elastomer, and the special-shaped end face rings are embedded into the gaps; the base is provided with a positioning column and a lower star-shaped boss, and a plurality of lower penetrating holes are formed in the base in a penetrating mode; an upper star-shaped boss is arranged on one side of the upper base, and the upper base is provided with an injection molding hole and upper penetrating holes; a molding cavity is formed in the middle of the middle base; and fixing screws sequentially penetrate through the upperpenetrating holes, middle penetrating holes and the lower penetrating holes to fix and position the upper base, the middle base and the base. According to the end face wear-resistant elastic composite rotor and the elastomer production mold thereof, the structure is simple, maintenance is convenient, the metal powder transporting effect is good, production and manufacture are easy, and wide application and popularization can be achieved.

Description

【Technical Field】 [0001] The present invention relates to the technical field of elastomer rotors, in particular to the technical field of wear-resistant elastomer rotors. 【Background technique】 [0002] When the ceramic powder is transported, due to the high solid content and high wear of the ceramic powder, the metal is likely to jam the pump body when transporting by the normally used positive displacement pump, and there are also elastic lobe rotor pumps for transporting metal particles. Easily to scratch the elastomer, the edge of the end face is the most severely scratched, the radial surface of the elastomer body has little effect on the ceramic powder transportation, but the edge of the end face often causes the elastomer to tear, metal secretion and metal parts in the cavity of the pump Contact affects the life of the pump body, and at the same time it is easy to jam the pump body. In this situation, it is necessary to design and improve the lobe rotor pump. The improved...

Problems solved by technology

[0002] When transporting ceramic powder, since the ceramic powder has a high solid content and a high-abrasion medium, the metal is easily stuck in the pump body when the positive displacement pump is usually used for transport, and there are also elastic cam rotor pumps for transport, metal particles It is easy to scratch the elastomer, and the edge of the end face is the most serious. The radial surface of the elastomer body has little effect on the transportation of ceramic powder, but the edge of the end face often causes tearing of the elastomer, metal secretion and metal parts in the pump body cavity. Contact will affect the life of the pump body, and it is also easy to get stuck in the pump body. In this situation, it is necessary to design and improve the cam rotor pump. In order to facilitate its mass production, it is also necessary to make injection molds for the improved elastomer rotor. design
