At present, China has entered a new normal stage of development, the growth of economic development has slowed down, the real economy has suffered a strong impact, and the Chinese economy is facing a wave of transformation. Transformation and upgrading have become the trend of the times. Lighting companies also need to quickly adjust their strategic plans, transform their development methods, enhance their core competitiveness, seize opportunities for transformation, and achieve new breakthroughs in development. Under the guidance of the Internet + and the Belt and Road strategy, the lighting industry has ushered in a new era of development. Without transformation, it will be dead, transformation and upgrading has become the main argument of the lighting industry, and traditional lighting companies are the first to bear the brunt. The lack of Foshan lighting, the change of NVC lighting, the full deployment of sunshine lighting and the ready-to-wear of Sanxiong Aurora all confirm the importance of transformation. Under the new situation, how to re-adapt and develop and realize the second take-off of traditional lighting enterprises has become a major issue for enterprises to think about. The decline of a generation of light kings For the lighting industry, 2015 is not ordinary, integrated mergers and acquisitions, price killing, shuffling waves one after another. For traditional lighting companies, it is the former listed capital crocodile, followed by LED recruits, and its competition is far more intense than the traditional era. The twists and turns of the Chinese lamp king Foshan lighting reflect the rough and difficult transition of traditional lighting enterprises. As a generation of light kings, Foshan Lighting started to get involved in LED lighting earlier, but its transformation of LED lighting is not smooth. From huge claims to falling profits to high-level exchanges, shareholders are easy to change, once the cash cows are now experiencing an eventful fall. According to the data, Foshan Lighting has tried to increase its transformation into LEDs in recent years. However, due to the lack of production technology in the middle and upper reaches and the weak growth of traditional businesses, the domestic LED lighting promotion has not been as expected, resulting in a decline in the company's performance. According to the financial report, Foshan Lighting achieved operating revenue of 2.232 billion yuan in the first three quarters of 2015, down 5.25% year-on-year, and net profit was 73.43 million yuan, down 75.6% year-on-year. In stark contrast to the peers' brilliant transcripts. From the outside world, this is also the real reason for the change of Foshan lighting. The reshuffle of the market and the continuous decline of Foshan Lighting may be one of the reasons for Osram to end the cooperation. The insiders said that the former shareholder Osram was trapped in the general lighting performance. The growth of the company is weak, and instead focuses on high-end lighting, and whether the vastness of the takeover can become a life-saving straw for Foshan's lighting transformation has also become the focus of attention in the industry. On December 7, 2015, Foshan Lighting announced that it had previously signed a share sale and purchase agreement with Osram Holdings Co., Ltd., the company's largest shareholder, and transferred 100% of the shares to Guangsheng's Guangdong Electronic Information Industry Group Co., Ltd. for RMB 2.62 billion. The transaction was completed on December 4. At this point, the actual controller of Foshan Lighting was changed to Guangxu, a subsidiary of the Guangdong State-owned Assets Supervision and Administration Commission. The vast control of Guoxing Optoelectronics and Foshan Lighting is mainly to open up the entire LED industry chain. The choice of Foshan Lighting is more due to the consideration of the whole industry chain. Guoxing Optoelectronics has a leading edge in the upstream chip and packaging field, while Foshan Lighting has a significant competitiveness in the downstream application field. The synergy between the two parties is conducive to the creation of the entire industry chain. perfect. Earlier, Guo Yong, chairman of Guoxing Optoelectronics, said in an interview with industry media. See how the future of the Department of Broadcasting integrates operations, because they have been fighting for each other, and now it is under the treacherous battles. It is hard to say whether they can exert their respective advantages by 1+12. Wu Yulin, president of the Foshan Lighting Association, said.Excavator cylinder oil seals
â‘ Hardness:
Due to the scientific synthesis of high-molecular polyurethane elastomer materials using iron rubber, the higher the hardness, the higher the modulus, the smaller the elongation, and the better the wear resistance and heat resistance. Well, in the range of minus 35 degrees Celsius to 100 degrees Celsius, and at a pressure of 60 to 70 MPa, the maximum sealing performance can be guaranteed.
â‘¡Pressure resistance:
The use of viscoelastic seals made of nitrile rubber is the most complete protection against damage caused by back pressure. In the range of minus 55 degrees Celsius to 100 degrees Celsius, and under a pressure of 21MPa, due to the rubber The seal is often in a compressed state, so the compression performance of the rubber seal must be considered. It not only achieves enhanced anti-climbing performance and low friction resistance, but also has good performance in dealing with special low-temperature oil, and can also be used in combination with Anti-wear Ring double-purpose retaining ring BRL type.
â‘¢Prevention of oil leakage:
Sealing products made of polytetrafluoroethylene and nitrile rubber/PTFErubber; or seals made of nylon resin and nitrile rubber, which can be used in a wide range of applications with large pressure changes and fast sliding speeds According to the working condition, the input hydraulic pressure cutout is designed on the end face of the polytetrafluoroethylene ring to prevent penetration leakage. The maximum working temperature environment is minus 40 degrees Celsius to 160 degrees Celsius; the maximum working pressure is 50MPa.
