Ball valves are widely used in oil and natural gas transportation pipelines and chemical equipment. The service life of ball valves is significantly reduced especially under extreme working conditions. Remanufacturing technology can maximize the remaining value of failed valve components and extend their service life. Ball valves are widely used and have a huge market share. Recycling, remanufacturing and repairing ball valves can bring great economic and social benefits.
Remanufacturing for ball valves
In the industrial production process, many large-scale mechanical equipment have their key components worn, corroded or scrapped after long-term operation, which makes the production cost remain high and causes a waste of resources. Remanufacturing technology refers to the use of advanced surface treatment for secondary processing of damaged workpieces. The performance, quality and service life of the workpieces obtained through remanufacturing are improved compared to the original workpieces. China's earliest remanufacturing concept was proposed by an academician named Binshi Xu. Remanufacturing is the best way to save resources, and remanufacturing can make an important contribution to a conservation-oriented society.
Brush plating for ball valves
Brush plating is a technique used to restore and repair ball valves. This method involves the application of a thin layer of metal onto the surface of the valve using an electrode brush and a plating solution. The process is commonly used to repair worn or damaged areas on the valve, improving its functionality and extending its lifespan. The first step in brush plating for ball valves is to clean the surface thoroughly, removing any dirt, grease, or rust that may hinder the plating process. Once cleaned, an electrode brush is dipped into the plating solution and then applied directly to the damaged area. The brush acts as both an applicator and an electrode, allowing for precise control over where the metal coating is deposited. The plating solution contains metal ions that are attracted to the cathode (the valve) when an electric current is applied. As a result, a thin layer of metal builds up on the surface of the valve, effectively restoring its original dimensions and properties.
Brush plating offers several advantages over traditional methods such as welding or re-machining. Firstly, it allows for localized repairs without having to disassemble or remove the entire valve from its system. This saves time and reduces downtime in industrial processes. Secondly, brush plating provides excellent adhesion between the new metal layer and the existing surface. This ensures the durability and longevity of repairs while maintaining optimal performance.
In conclusion, brush plating for ball valves is a valuable technique that allows for efficient restoration and repair of these essential components. Its ability to provide localized repairs with excellent adhesion makes it a preferred choice in various industries where downtime must be minimized while ensuring optimal functionality of ball valves.
The remanufacturing industry has the characteristics of green environmental protection and resource conservation, contains great economic potential, and is in line with China's strategic policy of sustainable development. With the continuous development of surface treatment and repair technology, the efficiency of the remanufacturing industry and the performance of remanufactured products are constantly improving. Surface repair technology is the core of remanufacturing engineering. Brush plating is one of the remanufacturing technologies. Only a plating pen is required for brush plating. According to the principle of electrochemistry, the plating pen is the anode and the plated part is the cathode. The plating pen continuously supplies the plating liquid, and the metal ions in the plating liquid will discharge and crystallize on the plated parts, forming a metal covering layer. The size of the brush plating equipment is small, and the thickness of the metal coating produced can be controlled. However, other surface repair methods such as surfacing and thermal spraying do not have this feature. The brush plating is suitable for parts with inner holes, such as connecting rods or cylinder inner walls. Junhua Zhao and others used brush plating to remanufacture mechanical equipment in many industries such as the military industry, engineering machinery, and metallurgical machinery, achieving the purpose of reusing failed mechanical parts.
Traditional brush plating relies on manual operation by workers, which not only has low production efficiency but is also very labor intensive, which makes the output of remanufactured products with brush plating low. Zhenfeng Hu and others developed an automated brush plating machine for the remanufacturing process of engine blocks. This equipment not only solves the problem of low production efficiency, but the surface coating performance of the processed workpiece is also better than that of manual processing. Bin Wu and others used automated electroplating brush equipment to prepare Ni/n Al2O3 nano-coatings, and studied the mechanical properties of the nano-coatings.
The results showed that the hardness and wear resistance of the nano-coatings prepared by automated equipment were better than those prepared manually. Zhuan Huang and others used nano-brush plating to prepare a nanocomposite coating with special nickel as the bottom layer, nickel-coated nano-alumina and nickel-coated nano-silica as the surface layer on failed engine blades. Compared with the original coating, the hardness of the composite coating with nanoparticles is significantly increased, and the hydrogen penetration rate is reduced. Remanufactured blades not only perform better than the original design blades, but also bring greater economic benefits. At the same time, they make a breakthrough in foreign technological blockades and are of great significance to improving China's military strength. Automated brush plating and nanocomposite brush plating are both future research directions of brush plating , and both have good application prospects. They can not only improve the quality of coatings, but also increase the efficiency of the industrialization of brush plating. Brush plating can complete the operation on the surface of smaller parts, but the cost is higher.
