Technical Field

The invention relates to a delivery pump, in particular to an acid-resistant and alkali-resistant delivery pump.

Background

Hydrochloric acid, commonly known as hydrochloric acid, is an aqueous solution of hydrogen chloride (HCl) gas and is a colorless and transparent monobasic strong acid. Hydrochloric acid has a very strong volatility, so that a white mist can be seen above a container containing concentrated hydrochloric acid after the container is opened, and actually, small hydrochloric acid droplets are generated by combining hydrogen chloride with water vapor in the air after the hydrogen chloride is volatilized. Since hydrochloric acid is a chemical raw material, the hydrochloric acid is different from common materials in the processes of production, processing, transportation and use, a delivery pump of the hydrochloric acid is different from a concrete delivery pump, and the like, and if the hydrochloric acid is transported in a conventional mode, the hydrochloric acid is easy to generate harm such as corrosion, toxic gas and the like.

Disclosure of Invention

The invention provides the acid-resistant and alkali-resistant delivery pump which is simple in structure, convenient to install, stable in work, free of noise, low in production cost, long in service life, good in sealing performance, good in cooling effect, safe, environment-friendly, corrosion-resistant and environment-friendly, and capable of improving the work efficiency.

The technical scheme of the invention is as follows: the conveying pump comprises a fixed ring mounting seat, a shaft seal jacket, a cooling circulation pipe, a pump body front cover, a self-suction barrel, a fixed ring, a spring and a telescopic ring, wherein the fixed ring mounting seat, the fixed ring, a rotating ring, a telescopic ring gasket, the spring and the telescopic ring are fixedly connected and then arranged in the shaft seal jacket, the fixed ring is fixedly arranged in the fixed ring mounting seat, a cavity is arranged in the fixed ring, the rotating ring is arranged in the cavity of the fixed ring, a cavity is arranged in the rotating ring, the telescopic ring gasket is arranged in the cavity of the rotating ring, a step circle is arranged in the rotating ring, one end of the spring is clamped on the step circle of the rotating ring, the other end of the spring is arranged in the telescopic ring, threads are arranged on the outer wall of the telescopic ring, the self-suction barrel is arranged at the front part of the conveying pump, the pump body front cover is arranged at the upper part of the conveying, one end of the cooling circulation pipe is communicated to the self-suction barrel, and the other end of the cooling circulation pipe is arranged outside the shaft seal jacket.

The invention has the advantages of simple structure, convenient installation, stable work, no noise, low production cost, long service life, good sealing performance, improved work efficiency, good cooling effect, safety, environmental protection and corrosion resistance.
