The upgrading of pump and valve industry has grasped the laser "golden touch"
ball valves, gate valves, pump blades, sealing surfaces... A number of leading pump and valve enterprises in our city, such as Chaoda valve and Nanfang valve, have mastered the laser "golden touch"
to upgrade traditional pump and valve products to high-end pump and valve products by using laser technology, Successfully opened up a new high-end pump and valve market
ball valves, gate valves, pump blades, sealing surfaces... Chaoda valves, Nanfang valves and other leading pump and valve enterprises in our city stood out among more than 7000 pump and valve manufacturers nationwide because they used laser technology to strengthen the surface of key pump and valve parts and mastered the laser "golden touch" of upgrading traditional pump and valve products to high-end pump and valve products
laser technology is becoming the "killer mace" for R & D and production of high-end pump and valve products. Wenzhou pump and valve industry upgrading is embarking on the road of laser, opening up a new blue ocean towards the high-end pump and valve market
Chaoda valve breaks the import monopoly of "special ball valve"
it is a huge machine operating arm. While spraying coating material powder on the substrate to be coated, it emits high-energy density laser beam for irradiation and heating to melt it with the substrate surface and solidify rapidly. When the laser beam stops irradiating, a surface coating with metallurgical bonding is formed on the surface of the substrate, which is called laser cladding
yesterday, we saw this glowing and heating cladding scene in Ruian laser application engineering demonstration center. In just a few seconds, a thin layer of coating has been firmly covered on the processed substrate. The surface is smooth and uniform
"it is this new cladding process that gives us more technical support for the research and development of special wear-resistant ball valves." In the list of the first prize of Wenzhou science and Technology Progress Award in 2014, Chaoda Valve Group Co., Ltd. (hereinafter referred to as Chaoda valve) is listed in the project of high parameter special wear-resistant ball valve, and its product technology is considered to have reached the international advanced level. As one of the main implementers of the project, qiuxiaolai, chief engineer of Chaoda valve, believes that laser cladding technology plays a key role in the process of product development
"in the past, the high parameter special wear-resistant series ball valves were imported, which were not only expensive, but also waiting for goods for a long time. However, the high parameter special ball valve developed by us was recognized by the high-end market after it was introduced to the market, becoming a substitute for the imported special ball valve (valve), breaking the domestic monopoly of" special ball valve " Qiu Xiaolai introduced that since the research and development of high parameter special ball valve, Chaoda valve has successively invested more than 10 million yuan to solve a large number of technical problems. The application of laser cladding technology can achieve the effects of small impact on the substrate, small deformation of the workpiece, improving the hardness, wear resistance and corrosion resistance of the cladding material and high compactness, and solve the problems of easy wear, falling off and short service life of the ball wear-resistant coating, Ensure the quality of products
at present, the high parameter special wear-resistant ball valve developed by Chaoda valve has been widely used in the harsh working conditions of nearly 200 major industrial projects at home and abroad in the fields of coal chemical industry, coal to liquid, polysilicon, silicone, petroleum, chemical industry, electric power and military industry. The vast majority of projects are national major engineering projects, including Texaco (GE) gasification unit with the highest pressure in the world, the largest gasification unit of a single set of synthetic ammonia in the world The world's largest coal to liquid project, the world's largest methanol to olefin project and national major military projects are also widely adopted
"its output value has accounted for one fourth of the company's annual output value, and has become our star product." Qiu Xiaolai said that since 2010, the output value of Chaoda valve's high parameter special ball valve has accumulated more than 400million yuan, earning more than US $9 million in foreign exchange
research and develop special laser equipment for pump and valve, and open up a new blue ocean in the high-end pump and valve market
like Chaoda valve, the leading pump and valve enterprises in our city have specialized in laser application technology one after another, making use of the unique advantages of laser technology to improve product quality, enhance product added value, and develop high-end pump and valve markets such as special pump and valve. The public innovation service platform similar to Ruian laser application engineering demonstration center provides a practice stage for these enterprises' technical creativity
Rui'an laser application engineering demonstration center, which was officially registered in March this year, is a wholly-owned subsidiary of Rui'an Boye Laser Application Technology Co., Ltd. It provides services in laser manufacturing and remanufacture, laser fine processing, laser product testing, laser application process research and development and related technical consulting
"even if the same laser technology is applied, the processing technology of each workpiece is different. It is necessary to carry out targeted development on the processing technology of different workpieces. The most suitable processing technology can be obtained only after countless experiments and samples are tested. We will help enterprises develop this set of laser technology application scheme." Wuxuhao, chief engineer of Ruian Boye Laser Application Technology Co., Ltd., has been staying in the laser application engineering demonstration center for a long time, concentrating on studying various laser surface treatment processes and doing "learning" behind closed doors. When he arrived, his "laboratory" was glittering with electro-optic flint to conduct laser cladding for the valve body sealing surface of a Ryanair valve enterprise
"in the process of using the pump valve products, they have been in the medium for a long time and have been washed and corroded by the medium. High hardness, wear resistance and corrosion resistance are the necessary characteristics of the products. After being treated by the laser cladding technology, the effect they can achieve is often significantly better than the traditional process." Wuxuhao made a comparison between traditional surfacing and laser cladding and explained that the smoother process, higher product performance, and the application of laser technology can make the pump valve products easy to achieve high added value, move towards the R & D direction of special valves, and improve product competitiveness
at present, the laser application engineering demonstration center has studied the laser application process for more than 20 enterprises, and the samples manufactured for them have passed the test. Three pump and valve enterprises in our city, including Nanfang investment group, have reached a long-term cooperative relationship with the center, and handed over their products to them for processing and production
"we have cooperated with the laser application demonstration center for some products of gate valve, stop valve and check valve to conduct surface treatment on the sealing surface. Now the testing results of the products are very good, waiting for the customer's use results." Weiyubin, general manager of Nanfang investment group and chief engineer of valves, said that after a year of process research, a small amount of laser application technology has been put into production at the beginning of this year. However, for relatively mature processes, he is more eager to supply more professional laser equipment and market-oriented coating materials. "The laser technology we need is relatively simple, and the cladding technology is enough. However, the existing laser equipment basically has multiple functions, with high prices, large floor space and relatively high failure rate. With the progress of society, we can only entrust a small number of products to a third party for processing."
in this regard, zhangdawei, a professor of Wenzhou University who participated in a number of laser technology application research and development projects, said that at present, the process research and development of laser technology application in several projects he participated in have been relatively mature. In the next step, they plan to communicate and cooperate with domestic laser equipment manufacturers to design and manufacture lasers for the pump and valve industry, making it possible for laser technology to be applied to mass production of products. "With such equipment, the existing surface treatment process of the enterprise can be thoroughly transformed and upgraded, and the control of product quality can be more accurate, so as to produce more high-end products and enhance the competitiveness of the industry."The high-end pump and valve market of nuggets is inseparable from laser

the pump and valve industry, as one of the five pillar industries that the city focuses on developing, accounts for more than 1/3 of the national market share. At present, there are nearly 2000 enterprises in the city. Last year, the total industrial output value reached 31billion yuan, and the sales output value is expected to exceed 50billion yuan by 2016. However, after decades of development, Wenzhou pump and valve industry has encountered a development bottleneck of serious homogenization and low-level competition among enterprises, relative surplus of low-end general-purpose products, and difficult access to the high-end pump and valve market, which has prompted more and more pump and valve enterprises like Chaoda valve to increase their investment in scientific and technological innovation and march into high-end pump and valve products such as ultra-zero, high and low temperature, nuclear power, coal retaining iron shaft or variable retaining frame chemical industry
in March this year, the city issued the guiding opinions for the implementation of the "May 10 industry cultivation and improvement project", which clearly stated that the pump and valve industry should focus on developing high-end pump and valve projects such as high temperature resistance, high pressure resistance and corrosion resistance, strive to build the largest innovative design and manufacturing base for intelligent system process equipment in China, use laser technology to improve and improve the wear resistance, corrosion resistance and high temperature resistance of pump and valve products, and extend the service life of valves, Is an effective way. Foreign high-end pump and valve manufacturers generally use laser technology. Wenzhou pump and valve leading enterprises such as Chaoda valve, Nanfang valve and modern pump industry are also enjoying the economic and social benefits brought by the use of laser technology
laser technology is indispensable for Wenzhou pump and valve industry to achieve the goal of upgrading from traditional massive economic agglomeration to modern industrial cluster, and win the recognition of high-end pump and valve market with high-end quality and innovative strengthOn Saturday morning, the 2014 Wenzhou Laser Technology Application Innovation Conference held a special activity of the pump and valve industry in the international exchange hall on the second floor of the Municipal Science and Technology Museum.
