The role of hydraulic pump:
Hydraulic pump is a hydraulic component for hydraulic transmission to provide pressure liquid, is a kind of pump. Its function is to convert the mechanical energy of power machines (such as motors and internal combustion engines, etc.) into liquid pressure energy. Figure shows the working principle of single plunger pump. The CAM is driven by a motor to rotate. When the CAM plunger upward movement, the piston and cylinder formed by the sealing volume is reduced, oil extruded from the sealing volume, through the one-way valve to the place where you need to go. When the CAM is rotated to the curve of the falling part, the spring forces the plunger down, the formation of a certain vacuum, the oil in the oil tank under the action of atmospheric pressure into the sealing volume. The convex wheel keeps the plunger rising and falling, the sealing volume periodically decreases and increases, and the pump keeps absorbing and discharging oil.
Le Meimei's innovation leads the "surgery"
In the past ten years, with the vigorous development of the LED lighting industry and the creation of a group of innovative and powerful enterprises, Lemei Optoelectronics has grasped the innovative weapon and became the wave of technology and product competition. A company that lacks technological innovation capabilities is not competitive. In the words of Yuan Yanping, the president of Lemei Optoelectronics, this is also the result of Lemeimei Optoelectronics becoming a government construction project supplier from many cities in China, and its products are spread over more than 100 countries. Lemei's Optoelectronics Factory Map Technology Innovation Leads the way of technological innovation, it is easier said than done. Today, enterprise innovation usually has three modes: independent innovation, introduction of innovation, and cooperative innovation. To be the leader in the industry, we must combine these three models. Under the premise of thoroughly analyzing the development trend of the industry, we will realize technological innovation by focusing on independent innovation and introducing and cooperating with innovation. The introduction of innovation is not a blind copy, but draws on the ideas of the predecessors, summarizes its experiences and lessons, improves and perfects the existing technology, and puts a lot of energy into quality control in the production process. Yuan Yanping said that these models cannot be realized without the strong support of the beautiful and powerful technical team and production team. Since its inception, Ledemei Optoelectronics has incorporated technological innovation into the important agenda of corporate development. Relying on the research and development team of Mei Optoelectronics, the company is in the forefront of the industrial lighting products such as LED panel lights, ceiling lights, soft and hard light strips and fluorescent tubes. In Yuan Yanping's view, technological innovation is the secret of Le Meimei's leading industry. Throughout the growth of Le Mei Optoelectronics, it is not difficult to find that technological innovation is accompanied by every step of the company's development and growth. In 2003, Lemei Optoelectronics established a direct-insertion LED packaging line and invested in the research and development of application products. In the next two years, the innovative in-line packaging technology reduced the light decay of 30%-40%/year in the industry to 10 %; In 2007, it took the lead in using SMD patch products to solve industrial problems such as uneven illumination, small angle, and product heat dissipation; in 2008, under the impact of the economic crisis, the growth of production scale and sales performance increased sharply, and commercial lighting products were established. R&D direction; In 2012, it was awarded the national high-tech enterprise qualification, and its export volume jumped to the top three in the industry; in 2013, it established a sub-brand, Youmai, to build Dongguan New Industrial Park. All along, Lemei Optoelectronics has always focused on the development of LED lighting products, and actively explore how artificial light can be closer to natural light. In order to ensure the purity and consistency of the light source, Lemei has strict control from research and development to packaging to production, and through continuous practice and innovation, to master the core technology of lighting products. The company invests 10% of its profits every year in the research and development process. At the same time, the proportion of R&D personnel also accounts for about 10%, far exceeding the investment of other companies in the same industry. Yuan Yanping said that the huge R&D investment has made the beauty of music in the forefront of the industry in terms of technology research and development, structural design or product functions. The company has become a real technology leader in the LED lighting industry. Innovative products meet market needs The most important thing in the process of adapting new products to the market is that products must be continuously improved to meet changing market demands. Yuan Yanping said. From the market point of view, in the new products launched by Lemeimei in 2015, the lamp belt products mainly include 2835/5050 soft light strips, RGBW integrated soft light strips, colorful casings, frosted casing soft strips and other series. In commercial lighting, the new products include surface-mounted ceiling lamps, jade ceiling lamps and die-cast panel lamps. In order to meet the different needs of customers, Lemei Optoelectronics introduced surface-mounting accessories for panel lights and ceiling lights in the original installation method. Some of these products have been recognized by many customers as soon as they are available, and sales have continued to rise. It is worth mentioning that at present, the company still has some new products such as jade plate series ceiling lamp, elephant trunk lamp, die-cast panel lamp, etc., which are about to be officially launched. Although the sales volume is still unknown, it is predicted according to the attention of old customers. The prospects are very optimistic. However, any new product can't be perfect in one market, and it can't fully meet the needs of consumers in various regions, so the continuous improvement of new products is very important. Yuan Yanping said that under normal circumstances, Le Meimei judges the improvement direction of new products through the following ways: First, the market reaction. This requires judgment from sales, consumer willingness surveys and customer feedback; second, market demand differences in different regions. Market demand in each region may differ due to differences in the environment; third, the addition of new technologies. The LED lighting technology is changing with each passing day, and the emergence of new lighting technology is an important support for the new products to gradually improve. Only by doing the above three points, we will continue to improve the competitiveness of new products and ensure that each new product will not be eliminated in the ever-changing new lighting market. Development is fundamentally in line with the demand for innovation. The expansion of LED lighting market is one of the important development trends. On the one hand, the voice of global energy conservation and environmental protection is getting higher and higher, and the elimination of incandescent lamps is imminent. On the other hand, as reflected in the 12th Five-Year Plan, the national policy is The LED lighting industry is highly supported. Yuan Yanping said. Yuan Yanping pointed out that the development of the world economy and the improvement of human living standards will lead to an increase in the global demand for LED lighting products, and the LED lighting market is still promising. The price decline brought about by technology upgrading and cost control is another important development trend. Of course, the cost control mentioned here is fundamentally different from the cost reduction in the price war in the industry for killing chickens and taking eggs. In addition, the industrial model of domestic manufacturers from the downstream to the middle and upper reaches is also an important direction for future development. The upstream LED epitaxial wafers and chips account for about 70% of the industry's profits. This industry model is unstoppable driven by profit; finally, technology The trend of innovation and maturity is already a cliché. Nowadays we are concerned about the integration of intelligent LED lighting, optical communication is just tip of the iceberg, is the source of technological innovation to promote the development of the industry. Westernization movement in modern history once Learn the skills to self-reliance as the slogan, calls for national and foreign things serve China by learning Western technology to achieve the purpose of self-reliance, showing that comply with demands of technological innovation is the fundamental development. Merlot has the ability to carry out technological innovation, adhere to the fundamental research and development, to expand research and development team are closely related. Yuan Yanping said. Final interview, Yuan Yanping said that only by adhering to adapt to the needs of technological innovation, continuous research and development, market research team to grasp when market demand trends, when R & D team have the ability to quickly respond to the needs, overcome technical bottlenecks, the new product will be delivered in the shortest time in front of the public. Of course, the most important thing is that the beauty of music will continue to strictly control the quality of products, and strive to provide you with the best products and create the best lighting experience.
