At present, all the carbon skateboards used in domestic electric locomotives are imported from Germany, and no other enterprises in China have mastered their production technology. A few years ago, Sun Jihai, general manager of Penglai Superhard Composites Co., Ltd., learned this situation by chance, and was deeply attracted by the huge business opportunities. But how can a small private enterprise be able to compete with foreign big companies? This made Sun Jihai unable to do anything. Later, he learned from the Internet that the Russian National Institute of Graphite Research is at the world's leading level in the research and application of graphite structural materials. The developed electric locomotive carbon skateboard has been widely used in the Russian electrified railway system. This made Sun Jihai, who dared to stand on the shoulders of giants, think of marriage with foreign scientific research units. After painstaking contact and negotiation, the two sides finally reached a cooperation agreement.
Having a technical backing does not mean that a pure carbon skateboard that meets China's national conditions can be produced immediately. After digesting and absorbing the other related technologies and achievements, Sun Jihai immediately organized a group of his own research team, and after more than one year of research and development, he finally achieved success. The pure carbon skateboard produced is not only low in cost but also has a long service life. 1.5 to 2 times the same kind of products. After testing and on-site testing by the Ministry of Railways Product Quality Supervision and Inspection Center, the technical indicators of the skateboard meet the relevant technical conditions and standards of Germany and Russia, filling the domestic gap. Last year, the product won the second prize of Shandong Science and Technology Progress Award and was included in the 2007 National Key New Product Plan.
The process seems simple, and the hardships of it make Sun Jihai feel a lot. At present, Shandong Penglai Superhard Composite Materials Co., Ltd. has occupied the domestic pure carbon skateboard market, with an annual production capacity of 30,000 sets, becoming the only private high-tech enterprise in China that can produce high-quality, low-cost pure carbon skateboards.
A hydraulic pressure gauge is a device used to measure the pressure of a hydraulic system. It consists of a dial or digital display that shows the pressure reading in units of force per unit area, such as pounds per square inch (psi) or bar.
The gauge is typically connected to the hydraulic system through a pressure port or a pressure transducer. When the hydraulic fluid flows through the system, it exerts a force on the gauge, which is then converted into a pressure reading on the display.
Hydraulic pressure gauges are commonly used in various industries and applications, such as automotive, manufacturing, construction, and aerospace. They are essential for monitoring the pressure levels in hydraulic systems to ensure proper functioning and prevent damage or failure.
Some hydraulic pressure gauges are designed for specific pressure ranges, while others are adjustable or have a wide range of measurement capabilities. They may also have additional features like maximum pressure indicators, peak hold functions, or digital interfaces for data logging.
Overall, hydraulic pressure gauges play a crucial role in maintaining the performance and safety of hydraulic systems by providing accurate pressure readings for troubleshooting, maintenance, and operational purposes.
