Abstract

The invention relates to an acid-resistant and alkali-resistant delivery pump which comprises a fixed ring mounting seat, a shaft seal protective jacket, a cooling circulating pipe, a pump body frontcover, a self-absorption cylinder, a fixed ring, a spring and an expansion ring; a cavity is formed in the fixed ring; a rotating ring is arranged in the cavity of the fixed ring; a cavity is formed in the rotating ring; an expansion ring gasket is arranged in the cavity of the rotating ring; a stepped circle is arranged in the rotating ring; one end of the spring is clamped on the stepped circleof the rotating ring, and the other end of the spring is arranged in the expansion ring; a thread is arranged on the outer wall of the expansion ring; the self-absorption cylinder is arranged at the front part of the delivery pump; the pump body front cover is arranged at the upper part of the delivery pump; the cooling circulating pipe is arranged at the lower part of the delivery pump; and one end of the cooling circulating pipe is communicated into the self-absorption cylinder, and the other end of the cooling circulating pipe is arranged on the outer side of the shaft seal protective jacket. The acid-resistant and alkali-resistant delivery pump is simple in structure, convenient to mount, stable to operate, noiseless, low in production cost, high in sealing performance, good in coolingeffect, safe and environmentally-friendly, and corrosion-resistant, and the working efficiency of the acid-resistant and alkali-resistant delivery pump is improved.

Description

technical field [0001] The invention relates to a conveying pump, in particular to an acid and alkali resistant conveying pump. Background technique [0002] 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 is extremely volatile, so when you open the container containing concentrated hydrochloric acid, you can see white mist above it, which is actually small droplets of hydrochloric acid produced by the combination of hydrogen chloride volatilization and water vapor in the air. Since hydrochloric acid is a chemical raw material, it is different from ordinary materials in the process of production, processing, transportation, and use. Its delivery pump is different from concrete delivery pumps, and it is easy to Hazards such as corrosion and generation of toxic gases may occur. Contents of the invention [0003] In order to solve the abo...
