Traditional air compression technology has always been considered the best power source, because the air does not need money, easy access, small resistance, fast speed, and no fear of leakage (leakage point does not matter). In the glass bottle machinery has always occupied a major position in the formation of glass bottles for the stamping of products: the main stamping method in the compression method, the initial pressure in the pressure blowing process. Especially in some industries where mass production is mainly based on mass production, there is a view that the high speed of pneumatics is favorable to the molding of products. This has created two problems: One is mainly to use air pressure when purchasing equipment for large-scale production of smaller products. The second is to maintain the use of glass presses used in the original mass production.
The main features of the gas-liquid retrofit system are as follows:
First, the development of new technologies in the world is changing with each passing day. In addition to the traditional advantages of maintaining hydraulic pressure in hydraulic technology, high-speed hydraulic systems have been developed. The main fuel tank seal adopts the Golay circle combination technology, which greatly reduces the piston movement resistance and improves the starting performance. It has been used in ordinary cylinders and the speed can reach 1m/min. Hydraulic solenoid valve faultless high switching frequency technology is also very mature.
Second, the research on the influence of hydraulic pressure on the forming quality of products has been continuously deepened. The stress state in the forming of products has a significant effect on the effect of heat treatment on the subsequent tracks, and it requires a controlled forming force. The current hydraulic technology has provided such a means. From the control of the forming force to the mastering of the thickness of the product, the hydraulic technology can be simply and conveniently implemented.
Third, the comparison of gas-liquid system operation and maintenance: Pneumatic systems have always been easy to access, simple operation is an advantage. However, with the development of the level of production technology, it has become insufficient in some places. Pneumatic press exhaust emissions are loud and polluting. The main cylinder is bulky and maintenance inspection is inconvenient. Indiscriminate leakage has become a source of waste. Controls that are too simple are not conducive to improving product quality and technology.
As a result of the use of shockproof protection materials, coupled with special ergonomic design and unique reinforcement production technology, very solid and durable, popular. Laptop Document Bag in addition to a special shockproof computer protection layer, there is considerable space can be used for small items such as travel luggage. Many high quality shoulders backpack is also widely used as a sports travel bag. If you need go to business and study, the canvas backpack will be your best choosing. And also you could choose our other Sports Backpack.
