Vertical fluorine-lined pipeline chemical pump

Abstract

The invention discloses a vertical fluorine-lined pipeline chemical pump which comprises a pump, a pump lining, a pump cover, a pump cover lining, an impeller, an electric pump shaft, a shaft seal, a motor and a connecting frame. The connecting frame is mounted on the pump, and the motor is mounted on the connecting frame. The pump lining, the pump cover lining and the impeller are integrally formed structural parts made of F46 materials. The vertical fluorine-lined pipeline chemical pump has the advantages that the water pump is in a vertical mounting design, an inlet and an outlet of the pump are formed in the same line, and the nominal diameter of the inlet of the pump is identical to the nominal diameter of the outlet of the pump; the pump and the motor are coaxial, the selected pump seal is an exterior mechanical seal, selected movable and static rings are made of ceramic-graphite polytetrafluoroethylene, and a sealing part is made of high-quality F46; a high-quality carbon steel parts part is used as a lining in the impeller; parts of the vertical fluorine-lined pipeline chemical pump are high in hardness, abrasion resistance and corrosion resistance; a user can directly mount the vertical fluorine-lined pipeline chemical pump at an optional position of a pipeline just like a valve, the vertical fluorine-lined pipeline chemical pump can be used for delivering high-purity and high-corrosiveness chemical liquid, the motor can be placed and used in an outdoor environment after a rain cover is added to the motor, and accordingly the field construction investment can be reduced for the user.

Description

technical field [0001] The invention relates to a driving pump, in particular to a vertical fluorine-lined pipeline chemical pump. Background technique [0002] Since the water inlet channel of the vertically installed pump body is relatively complicated, it is difficult to form casting, injection molding or compression molding. Therefore, the pumps in the general chemical industry are all horizontal, so that the suction chamber of the pump is cylindrical or conical. The manufacturing process of the body becomes relatively simple. In this way, many users in the chemical industry have to choose horizontal chemical pumps when purchasing water pumps, so users have to change the pipeline, and the installation space of horizontal pumps is much larger than that of vertical pumps, which increases the cost of users. Infrastructure investment. [0003] Due to factors such as poor fluidity and difficult molding of fluoroplastics, it is very difficult to produce fluoroplastic chemica...

AI Technical Summary

Problems solved by technology

[0003] 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

[0004] 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.

[0005] Moreover, the common vertical fluorine-lined pipeline chemical pumps on the market have few specifications, and the degree of universalization of parts is not high.
