NOUFERROUS METALLURGICAL EQUIPMENT

As the key equipment of slurry transportation, diaphragm pump plays an important role in the production process. For the transportation of corrosive slurry, it is necessary to carry out anti-corrosion treatment for the overflow part of diaphragm pump or select anti-corrosion materials, especially for the medium with strong corrosiveness. For hydrochloric acid and other strong acid pastes with strong corrosivity to metal materials, the general metal can not meet the corrosion resistance requirements, and the metal that can meet the corrosion resistance requirements has high cost, which is not suitable for diaphragm pump equipment. In this paper, the rubber lining anti-corrosion technology with outstanding anti-corrosion performance is combined with the traditional diaphragm pump buffer structure, and a kind of anti-corrosion lining diaphragm pump inlet and outlet buffer structure is developed, which can solve the problem of corrosive slurry transportation with strong acid.
