Fluoroplastic lining centrifugal pump

Abstract

The invention discloses a fluoroplastic lining centrifugal pump which comprises a pump body. A feeding opening is formed in one side of the pump body. A discharging opening is formed in one side, awayfrom the feeding opening, of the pump body. A feeding pipe is connected between the pump body and the feeding opening. A discharging pipe is connected between the pump body and the discharging opening. A lining is arranged in the pump body. An impeller is arranged in the lining. According to the fluoroplastic lining centrifugal pump, by arranging an anti-corrosion clamping ring, in the using process, the feeding pipe is connected with the feeding opening, then the anti-corrosion clamping ring is aligned to the connecting portion of the feeding pipe and the feeding opening, a moving ring is moved to enable an anti-corrosion layer to completely cover the connecting portion, finally, a butterfly nut on the outer side of a screw is screwed down, the anti-corrosion clamping ring is fixed, after the anti-corrosion clamping ring is used for a period of time, the butterfly nut can be loosened, a new anti-corrosion clamping ring is replaced, the device can seal a gap in the connecting portionof the feeding pipe and the feeding opening flexibly, the situation that the centrifugal pump works for a long time, and as a result, high-corrosion liquid in the pump body leaks can be prevented, andthe pump body is protected against corrosion.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a fluoroplastic-lined centrifugal pump. Background technique [0002] Fluoroplastic-lined centrifugal pumps are designed and produced in accordance with international standards and combined with the processing technology of non-metallic pumps. The pump body of the fluoroplastic-lined centrifugal pump is made of metal shell lined with polyfluoroethylene propylene (F46). The outlets are reinforced with cast steel body. This pump is suitable for transporting strong corrosive media with harsh conditions such as sulfuric acid, hydrochloric acid, acetic acid, hydrofluoric acid, nitric acid, aqua regia, strong alkali, strong oxidant, organic solvent, reducing agent, etc. of any concentration. It is the latest corrosion-resistant medium in the world. One of the equipment. [0003] After the existing fluoroplastic-lined centrifugal pump is used for a long time, the corrosive ...
