Basic use of acid discharge pump

With the continuous improvement of science and technology, the products of acid discharge pump valves will be intelligent, capable of monitoring pressure, flow, temperature and vibration, and evaluating the condition of the shaft, bearing and seal of the pump. able to diagnose the cause of the fault.

1. Overview of acid unloading pump:

Acid discharge pumps are widely used in pickling and painting processes in automobile manufacturing, electrolyte transportation in non-ferrous metal smelting, chlorine water, wastewater treatment and acid addition in ion-exchange membrane caustic soda projects, and the use temperature is-20 ℃ ~ 100 ℃. The IHF centrifugal pump is designed according to the international standard, the pump body is lined with fluoroplastic, the impeller and the pump cover are pressed with metal embedded fluoroplastic alloy, the shaft seal adopts advanced external bellows mechanical seal, and the static ring is made of 99.9% alumina ceramic. The moving ring adopts tetrafluorine filling material, which is characterized by good corrosion resistance and wear resistance.

2.Selection of mechanical seal for acid unloading pump:

The acid discharge pump adopts the most advanced external type tetrafluoro bellows mechanical seal, which is characterized by compensating the radial runout of the pump shaft, single face seal external loading and unloading, intuitive working condition, good corrosion and wear resistant seal performance and multi-layer protection, prolonging the service life of the machine seal. For conveying corrosive media containing impurity particles, it can be equipped with uncooled receipt end face hard-to-hard (silicon carbide to silicon carbide) mechanical seal, and special corrosive media such as strong alkali and hydrofluoric acid with pressureless sintered silicon carbide seal; when selecting the type, users should take into account the solid content in the medium and the special corrosiveness of the medium. .

3.The use of acid unloading pump:

The corrosion resistance and wear resistance of the acid discharge pump have been confirmed in practical use and unanimously recognized by the majority of users. at present, it has been widely used in: corrosive medium transport in chemical production, chlorine water wastewater treatment and acid addition process in ion-exchange membrane caustic soda projects (at present, most of the pumps for ion-exchange membrane caustic soda projects in China are used by our company to unload acid pumps), electrolyte transportation in non-ferrous metal smelting, pickling process in automobile manufacturing. And pharmaceutical, petroleum, electric power, electroplating, dyes, pesticides, paper, food, textile and many other industries, in the temperature range of-85 ℃ ~ 150 ℃ for a long time to transport any concentration of sulfuric acid, hydrochloric acid, hydrofluoric acid, nitric acid, aqua regia, strong alkali, strong oxidants, organic solvents, reducing agents and other strong corrosion media without damage, is currently one of the most popular pump equipment.
