Hydraulic cylinders are an important component of the hydraulic system of construction machinery, used to convert hydraulic energy into mechanical energy,
Convert the pressure of hydraulic oil into linear or rotational motion to drive various working components of construction machinery. The sealing components of hydraulic cylinders are key components to ensure their normal operation. If the sealing components are damaged or aged, it can lead to hydraulic oil leakage, hydraulic cylinder failure, and other problems, affecting the normal operation of construction machinery.
Therefore, the application of XCMG hydraulic cylinder repair kit can effectively solve the sealing problem of hydraulic cylinders,
Extend the service life of hydraulic cylinders and improve the efficiency of construction machinery.
LED lighting companies need the spirit of self-innovation
On October 7th, the Nobel Prize Selection Committee of the Royal Swedish Academy of Sciences announced that it will award the 2014 Nobel Prize in Physics to the 85-year-old Japanese scientist Akasaka Akira and the 54-year-old Amano, and the 60-year-old Japanese-American scientist Nakamura Shuji. In recognition of their contribution to the discovery of new, efficient and environmentally friendly light sources, the high-efficiency blue light-emitting diodes (LEDs) invented by the three winners brought a bright, energy-efficient white light source. As a heavyweight expert in the LED lighting industry, Tang Guoqing, general manager of Samsung LED Lighting China, said that the acquisition of Nobel by Blue LED is a boon to the entire LED lighting industry. However, he stressed that the LED industry is highly competitive. Now there are chip manufacturers or package manufacturers and lighting manufacturers directly combined. Your company is leaning forward in the industry chain, or relying on it. You still have to think about it. Maybe it will be ok in 3 years, and there may be problems in 5 years. Companies must have the ability to self-innovate and self-innovate in order to stand in the market. The LED lighting market has started quickly, and the company has positioned itself in the market segment. Zhou Xuejun, the marketing director of Philips Lumileds Asia, said that with the improvement of LED light efficiency and price decline, it will reach a sweet spot, and the market will grow rapidly. From 2014 to 2018, LED applications, Still growing with illuminating energy, the estimated compound annual growth rate of the relevant output value is still as high as 19, followed by automotive lighting 9, and the flash LED for photographic applications also has a compound annual growth rate of 4. At present, the most widely used panel backlight application is because the penetration rate is close to 100, and the future is facing the pressure of recession. The annual compound growth rate is -5. Dou Linping, secretary general of the China Lighting Society, analyzes the future trend of LED lighting. amazing. The industry has a high growth rate, and only some high-quality companies have performed well. In the past two years, there was a surplus of LEDs. In 2014, there were 20,000 LED lighting companies in China. The output value of lighting was only 480 billion in 2013. Even if the growth rate of 15 is maintained next year, the market scale will reach 600 billion. Only 5,000 companies in the next three years will be able to Survive. Tang Guoqing believes that LED lighting companies are now on the scale of inertia thinking, in the market positioning on the pursuit of greater demand, such as the mainland's Sanan return to Xiamen, suddenly become the national team, MOCVD number from the original 170 units, and then plan to increase 200 units. Tongfang 700 million holding Zhen Mingli, and Guangzhou's Asia First, the industrial chain expanded to include the extension of Nantong Tongfang, the bright and beautiful packaging and indoor and outdoor lighting, is developing in the direction of seeking. But for SMEs, this is obviously unreasonable. He clearly pointed out that this is a segmentation era, where is your market segment? For example, in 2013, LED street light Qinshang Optoelectronics ranked first in the domestic market, and Huapu Yongming ranked second. Why can I do this? This is closely related to the professional division of labor. Tang Guoqing emphasized that we should have the spirit of self-innovation and the spirit of self-revolution in any industry. Philips, the world's lighting giant, was in pain in 2014. LED lighting was used in the global application. His left hand and his right hand were his lighting world. Finally, Philips split the lighting. Foshan Lighting, one of the representatives of traditional lighting companies, is undergoing self-innovation. Pan Jie, chairman of Foshan Lighting, said that there are two sets of systems in the past, traditional lighting has more than 2 billion sales; the other is LED lighting. Transforming from a light bulb to do LEDs is stressful. Pan Jie said that the products of six months ago can not be sold now, and the replacement is very fast. The lighting industry chain is long. Now everyone likes to cross the border. Buddha photos also want to be engineers. In the face of temptation, they must learn to do subtraction. Innovation based on products and technology, the future development of the company can be expected Tang Guoqing said that innovative technology can change the development trend of the LED market. For example, go to the gold wire, go to the bracket, that is, the so-called unpackaged chip, its characteristics are: flip chip, no gold wire, further improved reliability; new package structure, no bracket; phosphor film technology, directly attached to the inverted With the surface of the chip, strict light color consistency can be achieved; the chip directly solders the heat sink platform, the thermal resistance is greatly reduced, and the same device volume can provide more power. Tang Guoqing pointed out that the mass production of unpackaged chips is now a difficult point because the process is very difficult. But once the existing technology is broken and the scale production is entered, the real cost-effective era is here. Zhongshan Xiaolan's stereo photoelectric use Samsung FCLED has made certain breakthroughs in indoor and outdoor lighting products. It can be directly applied to street lamps and mining lamps in outdoor lighting products. Especially for indoor lighting products, part of the replacement of COB, high reliability, high current, chip combination, optical design is more flexible. Stereo Optoelectronics uses the high-precision thick-film circuit technology of military quality to make the substrate, which makes the product on the basis of super high cost performance, and guarantees the excellent performance and super stability of the product, which brings a rapid promotion of FCLED in China. A good start. Dou Linping, secretary-general of the China Lighting Society, also solemnly warned that in the future LED market competition, in addition to the LED lighting market channels, products and technologies themselves are fundamental to the development of enterprises. The channel is successful again, there is no good product, and it cannot support the future development of the company.
