Valve re -manufacturing: Misty dial and start seeing flowers

As part of the circular economy, the valve re -manufacturing is not a small number of enterprises. However, for many users, the re -manufacturing of the valve is often like "looking at flowers in the fog", which is expected to be incomplete. Is the valve re -manufacturing?

“我国阀门再制造产业发展仍处于初级阶段，但积极开展阀门再制造在促进节能减排降本方面效益显著，是一件值得干、有干头、能干好的大事。”中国机电装备维修与Li Xingsheng, Secretary -General of the Real Estate Association (hereinafter referred to as the "China Machine Victoria Association") Valve Maintenance and Reboning Branch, said on June 20 that in response to the current industry status, the government, enterprises, users, media, etc. must work together to remove the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, let the fog, and let the fog and let the fog and let the fog. The application income and market prospects made by valve re -manufacturing can be visible and enough.

Re -manufacture, benefit

50%reduction, 60%energy conservation, 70%of the materials, 80%reduction of emission reduction

The so -called valve re -manufacturing refers to the process of processing its main components (castings) and replacing other components for some functional valves, and re -assembled after replacing other components, and testing the process of all qualified standards. According to Li Xingsheng, valves, as general equipment products, have the characteristics of wide application surfaces and large stock assets. my country has now become the world's largest valve manufacturer and consumer country, which mainly meets the needs of new projects and part of the construction projects -the latter more than 30%of each year needs to be replaced and maintained. Therefore, the development of valves has a broad market foundation.

It is understood that the valve raw materials involve a variety of industrial basic materials, and the products are all over the national economy. The re -manufacturing process is a typical re -cycle, which can meet the principle of "3R" (reduction, reuse, and cycle) of the circular economy.

"The petrochemical industry has the characteristics of high temperature, high pressure, high erosion, and strong wear. It is an important application area of ​​my country's valve products, especially the service life of special operating valves for more than one year." Li Xingsheng said that encouraging the valve industry to encourage the valve industry Development and rebuilding are important ways to promote the use of recycling, reduce environmental pollution, and help achieve the goal of "double carbon".

"Compared to manufacturing new products, re -manufacturing products can not only reduce costs by 50%, but also save 60%of energy and 70%of the materials. Environmental benefits. "Li Xingsheng believes that the development of valves has a broad market prospect.

Zhao Haiyan, an expert in the development of the Valve Valves of the China Machinery Victoria Association, said that in the long -term production and operation, enterprises often have a large number of valve spare parts inventory due to the installation of remaining and elimination of technical reform. For example, a chemical enterprise in Shandong has a long -term storage of nearly 160 million yuan in the valve in recent years. The valve re -manufacturing can eliminate the inventory of the backlog of user enterprises, forming a secondary marketization, and driving the entire industry's resources to save use and circular economy development, which is worth trying to promote it.

Create again, benefit innovation

Help high -end valve localization and technical talent reserves

According to industry experts, the re -manufacturing of the valve is not the maintenance and repairs of traditional methods, but uses modern testing technology, reverse engineering technology, material engineering technology, high -tech, as well as advanced technologies such as pile welding technology, thermal spray technology, additive manufacturing, and other advanced processes. Combined Design theory, technical repair and performance upgrades of waste equipment. Reconstruction products can reach or even exceed the original new products in terms of technical performance. Its core is the in -depth integration of advanced manufacturing and modern service industries.

Li Xingsheng said that re -manufacturing is an upgraded version of maintenance and maintenance. The development of valve re -manufacturing is of great significance for high -end valve domestic technology innovation and high -end talent training reserves. Zhu Rongchi, chairman of Wuxi Audi Fluid Control Technology Co., Ltd. also said that companies with the ability to make re -manufacturing and inspection and repair services have been entrusted with the re -manufacturing of valves, especially high -end valves, which can promote the localization of high -end valves from two aspects. The first is to understand the technical performance of foreign products through inspection and re -manufacturing, and master the technical difficulties of domestic production and development technology.

"On the contrary, the localization of high -end valves will also promote the improvement of inspection and repairs and re -manufacturing levels. It can form a" double -wheel drive "business model to promote the research and development innovation of technical equipment." The technical accumulation of the process can realize the introduction, digestion and absorption of imported valve products, and innovation. Its heated temperature reduction reducing device (empty valve) has been successfully applied on the 4 million tons/year coal indirect liquefaction project of Shenhua, replacing imported products.

Create again, the road is still long

Still in the initial stage, acceptance is to be improved

Li Xingsheng said that in developed countries and regions such as the United States, Japan, and Europe, the re -manufacturing of valves has become a mature industry. Among them, the United States re -manufacturing industry is at the forefront of the world. So, what is the status quo of related industries in China?

"The development of my country's valve re -manufacturing industry is still in the initial stage compared to the fields of automotive parts, internal combustion engines, machine tools, construction machinery." Li Xingsheng admitted that the post -market service of the valve still uses valve manufacturing enterprises and professional valve inspections. The maintenance company provides users with maintenance services.

The author learned that a considerable number of companies in the oil and chemical industries at present have little knowledge of the valve, or they only hear their names and puzzled them. "It is necessary to promote and popularize the concept of re -manufacturing of user companies." Zhang Pan, director of the equipment director of China Coal Jiuxin Jiaohua Co., Ltd., said that at present many user companies are still doubtful about the quality of re -manufacturing valve products. As a senior engineer in the field of valve applications, Zhang Pan has rich experience in valve inspection and maintenance. He said that there are some chaos in the valve industry, and many valve products are not strictly controlled when they leave the factory. It is easy to leak at the scene. The valve subject is generally good, and often some small parts have problems. The re -manufacturing of the valve can make these valves "new".

"At present, the promotion and guidance of the valve re -manufacturing and guidance are not enough, and the standard system is not complete. Although the user company has initially possessed the basic understanding of the re -manufacturing valve products, it is still unclear about the quality of key valve re -manufacturing products. It affects the development of the valve re -manufacturing industry. "Li Xingsheng said that in view of this, the" valve product re -manufacturing universal technical specification "group standards organized by the branch organization should be re -manufactured by the quality and service life of the re -manufacturing valve For specific requirements, if it can be effectively implemented, I believe that more and more valve users will choose valve products to make services.

Create again, need to cooperate

Establish an industrial ecology and form an overall joint force

Many industry experts said that my country's valve re -manufacturing should condense all parties, focusing on establishing a standardized and orderly and healthy industrial ecology.

Zhao Haiyan proposed that the development of valve re -manufacturing needs to be paid attention to from the national level, and also requires excellent industry standards to regulate and guide. At present, my country's valve manufacturers and professional maintenance manufacturers with strong technical strength have actually carried out the valve maintenance business in accordance with the requirements of re -manufacturing, but the re -manufacturing technical means and standard system need to be improved. It is reported that in recent years, the branches have organized all parties in the industry to continue to make efforts in the preparation of relevant standards and declarations, and also called on the valve to make re -manufacturing into the national "Reboning Product Catalog".

Liang Lianjin, the technical director of Shanghai Kaixi Valve Co., Ltd., said that the development of the valve re -manufacturing industry not only requires a perfect factory re -manufacturing system, but also establish a standardized test assessment system, build a post -manufacturing test platform, and establish a re -manufacturing level assessment assessment Authoritative organization with ability.

Zhao Haiyan also said that information technology such as the Industrial Internet can also invest in valve and re -manufacturing. Through timely online monitoring valve status, collect valve operation data and send it to the equipment management data analysis software to reasonably arrange the predictive maintenance of the valve to achieve it, realize the realization "Re -use" the intelligent management and intelligent improvement of subsequent markets.

Li Xingsheng believes that it should also organize the promotion and promotion activities of valve re -manufacturing products, enhance users' awareness of the concept of re -manufacturing products, strengthen the training and exchanges of re -manufacturing technology, mobilize the enthusiasm of enterprises to produce product production, form a development and re -manufacturing manufacturing The overall joint force of the industry.
