Heat dissipation type fluorine lining self-sucking chemical pump

Abstract

The invention provides a heat dissipation type fluorine lining self-sucking chemical pump. A main body of the chemical pump comprises a pump body. The pump body is internally provided with an impeller. An inner cavity of the pump body is internally provided with a fluorine lining inner sleeve. The fluorine lining inner sleeve is closely attached to the inner cavity of the pump body. The wall of the inner cavity of the pump body is provided with dense clamping ring grooves. The outer wall of the fluorine lining inner sleeve is provided with dense convex strips. The convex strips are arranged in the clamping ring grooves. The heat dissipation type fluorine lining self-sucking chemical pump has the beneficial effects that the design is novel; the structure is simple; the fluorine lining inner sleeve makes large-area contact with the pump body, the effect that absorbed heat on the fluorine lining inner sleeve is rapidly and efficiently transmitted to the pump body is ensured, and thus the heat is dissipated from the pump body rapidly; the effect is obvious; and the convenient and efficient effects are achieved.

Description

technical field [0001] The invention relates to the technical field of pumps and valves, in particular to a heat dissipation type fluorine-lined self-priming chemical pump. Background technique [0002] The working principle of the self-priming pump is to fill the pump casing with water before starting the pump. After starting, the impeller rotates at high speed to make the water in the impeller channel flow to the volute. The air in the tube enters the pump and travels through the impeller channel to the outer edge. The self-priming pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install a bottom valve in the pipeline. Just ensure that there is a quantitative suction liquid stored in the pump body before work. Different liquids can use self-priming pumps of different materials. With the continuous...

Problems solved by technology

There is no need to install a bottom valve in the pipeline. Just ensure that there is a quantitative suction liquid stored in the pump body before work. Different liquids can use self-priming pumps of different materials. With the continuous improvement of technology, self-priming pumps are also used in various fields. Diverse, in some chemical companies, because a large amount of acid and alkali and highly corrosive liquids need to be transported, the traditional self-priming pump will have corrosion and aging problems when used, and the concentration of these problems will lead to self-priming The pump is aging and damaged

[0003] Fluorine-lined self-priming pumps have solved the corrosion problem of the above-mentioned self-priming pumps in the field of pump valves at the present stage. The process is made of metal casing tightly lined with fluoroplastics. The main flow-passing parts, impeller and pump cover, are made of metal inserts and outsourced with fluoroplastics at high temperature. The application of this method fully solves the aging problem of self-priming pumps. , but there will still be some disadvantages in actual use

[0004] Due to the poor high temperature resistance of fluoroplastics, in actual use, long-term delivery of high-temperature mesons will cause the fluoroplastics to soften and cause self-priming pumps to fail. Therefore, the heat absorbed by fluoroplastics must be dissipated quickly. , to ensure the safety of the pump body
