Anti-rust method of pump valve

China's pump valves are well-mainly concentrated in Zhejiang, Jiangsu, Fujian, Guangdong and Liaoning. In recent years, with the deepening of industrialization, the development trend of the pump valve is good.

Carbon steel, sprayed and nickel-plated, spray-resistant, nickel-plated, and a tungsten-plated alloy, corrosion-resistant rust can be better than stainless steel, but a bit expensive. Or use stainless steel, this is the easiest.

The phosphating of the hydraulic pump is the best, which can not only solve the rust prevention between the processes, but also solve the carbon deposition pollution problem of the hydraulic pump body. After asking me, I would like to know how the hydraulic pump and hydraulic valve are assembled and formed, and how they are protected against rust during storage. Also, do not wash before installation. Answer It is necessary to use general anti-rust oil during storage. Generally, it is necessary to clean the assembly before assembly. Large-scale companies have a cleaning line in the assembly plant and use hydrocarbon cleaning agents to clean the assembly line.

If only anti-rust before installation, you can consider using the current "VCI vapor phase anti-rust", anti-rust bag and anti-rust paper, the operation is very convenient; if you need to install after the anti-rust, anti-rust oil, or "anti-rust liquid "(The market is a new kind of neutral liquid).
