Pickling is a necessary process in many metal processing industries, such as wire rod, steel plate, pipe processing industry, screw and nut manufacturing and processing industry, stainless steel plate processing industry, coating industry, etc., all use pickling to remove black skin, oxides and Other pollutants, in order to facilitate the quality of processing.
In the production process of stainless steel, a metal oxide layer will be formed on the surface of the material after annealing. In order to remove the metal oxide layer, strengthen the surface of the stainless steel, and improve the corrosion resistance of the stainless steel, nitric acid, hydrofluoric acid or mixed acids are usually used to treat the stainless steel. The surface of the product is cleaned and oxidized. A large amount of iron ions, chromium ions, nickel ions, manganese ions and fluorine ions are dissolved in the cleaned pickling liquid wastewater.
ZhiJing series commonly used in the circulation of spent pickling solutions
A vertical pump is a chemical pump with the motor shaft perpendicular to the horizontal plane, using centrifugal force to throw out the sewage. It can always maintain vibration-free bass operation during operation.
Centrifugal pump is to fill the pump casing with liquid, the impeller will run fast, the fluid will have a high speed generated under the action of centrifugal force, high speed liquid through the gradually expanding pump casing channel, can be changed from dynamic pressure head to static pressure head.
Chemical vertical pumps are used for lifting, conveying and circulating liquids. It is used to pump out water by centrifugal force generated by the impeller driven by the rotation of the motor.
The chemical circulating vertical sewage pipeline pump has the characteristics of wide performance range, high efficiency, high mechanical, chemical and physical level, and convenient maintenance.
