The vacuum pump is the key component of the vacuum system, especially for the clean and high vacuum process. The vacuum pump is the key factor that determines the process quality. However, whether it is vacuum equipment manufacturers or vacuum equipment users, the selection of dry vacuum pump are faced with the high price and maintenance difficulties. Vacuum pumps are widely used in vacuum smelting, vacuum heat treatment, vacuum coating, electrical products, chemical pharmaceutical, vacuum simulation, electric light source, silicon crystal cultivation, water removal, plastic products, vacuum impregnation, vacuum (freeze) drying, refrigeration equipment, food Processing and packaging, automotive manufacturing and other industries. Dry spiral vacuum pump is the use of a pair of intermeshing helical rotor, maintaining a tiny gap between the rotor, making the vacuum pump operation without lubrication within the cavity, so there is no oil leakage back to the pollution problem. Through the patent rotor linear sealing effect, the ultimate pressure of up to 7.5 × 10-3Torr. Due to the short exhaust path and the ability to remove dust more than other types of vacuum pumps, the spiral vacuum pump can be applied to harsh processes such as PECVD and Etching because the rotor surface is coated with a special coating material. Pump temperature control precision dry spiral vacuum pump, inherited the previous generation vacuum pump excellent rotor design, while improving the shell cooling method, the use of water jacket indirect water cooling method to reduce the shell temperature, can more accurately control the pump Internal temperature, reduce sediment production, increase the life of the vacuum pump. High safety seal motor PS Series vacuum pump also fully patented water-cooled canned sealed motor, in addition to maintaining a lower motor temperature to increase the life of the motor, but also can completely avoid the risk of process gas leakage. Microcomputer control and comprehensive protection PS series vacuum pump can also be equipped with microcomputer controller, while monitoring motor current, motor temperature, housing temperature, cooling water flow, nitrogen flow and gearbox level, providing a complete vacuum pump security protection, Very suitable for optoelectronics, semiconductors, solar and TFT-LCD products such as the stability of the extremely demanding industries.
Round nut is a kind of large fastener, which is widely used in hydraulic oil cylinder and railway internal combustion engine equipment, so the relevant performance is also important. If the round nut is of good quality, it can save the cost of locomotive maintenance and reduce the labor intensity of maintenance workers.
