Problems solved by technology

[0002] Due to factors such as poor fluidity and difficult molding of fluoroplastics, it is difficult to produce fluoroplastic chemical pumps.
The shape of the channel of the common fluorine-lined chemical pump body in the market is complex, so the fluorine-lined molding mold is complicated and there are many runner sliders in the mold. The thickness of the fluoroplastic lining layer in the flow channel of the pump body is uneven, which is easy to crack and corrode
[0003] The inner hole of the existing fluorine-lined chemical pump impeller lining steel parts is a conical hole, so it is difficult to process the parts and inspect the semi-finished products after processing.
[0004] Moreover, the suspension and other parts of the common fluorine-lined chemical pumps in the market are not highly universal

Abstract

A PTFE-lined chemical pump comprises a base, a pump body, an impeller, a pump cover, a pump shaft, a suspension and a motor. The pump shaft is fixed on the suspension through two bearings. A link plate is disposed between the suspension and the pump body. The other end of the suspension is supported on the base through a suspension support. A pump body lining is disposed in the pump body. A pump cover lining is disposed in the pump cover. The pump body lining, the impeller and the pump cover lining are all integrally-formed structural parts of F46 material. The parts of the PTFE-lined chemical pump are highly universal and interchangeable. The PTFE-lined chemical pump is high in hardness, wear resistance and corrosion resistance and can be used for delivering chemical liquids high in purity and corrosiveness.

Description

technical field [0001] The invention relates to a chemical pump, in particular to a fluorine-lined chemical pump. Background technique [0002] Due to factors such as poor fluidity and difficult molding of fluoroplastics, it is very difficult to produce fluoroplastic chemical pumps. The shape of the channel of the common fluorine-lined chemical pump body in the market is complex, so the fluorine-lined molding mold is complicated and there are many runner sliders in the mold. The thickness of the fluoroplastic lining layer in the flow channel of the pump body is uneven, which is easy to crack and corrode. [0003] The inner hole of the existing fluorine-lined chemical pump impeller lining steel part is a conical hole, and the processing of the part and the inspection of the semi-finished product after processing are relatively difficult. [0004] Moreover, the suspension and other parts of common fluorine-lined chemical pumps in the market are not highly universal. Conten...
