What gas pump filters including

The use of mechanical, physical, chemical, physical and chemical methods such as container extraction in order to obtain and maintain a vacuum device. Vacuum pumps and other equipment (such as vacuum container, vacuum valves, vacuum gauges, connecting pipes, etc.) consisting of a vacuum system, widely used in electronics, metallurgy, chemical, food, machinery, pharmaceuticals, aerospace and other sectors. According to their works, basically divided into a gas pump filters and gas trap pump types. Gas pump: 1, liquid ring vacuum pump (water ring vacuum pump) 2, 3 reciprocating pumps, rotary vane vacuum pump 4, 5 fixed vane vacuum pumps, rotary piston vacuum pump 6, 7 trochoidal gas pump filters, dry vacuum pump 8 , Roots vacuum pump 9, molecular pumps 10, 11 tractor-molecular pump, vacuum pump 12 compound, water jet pump 13, a gas jet pumps 14, 15 steam jet pumps and diffusion pumps and other gases trap pumps include: adsorption pumps and cryogenic pumps, etc. . Currently the most widely used industrial water ringmanual fuel pump and rotary vane vacuum pump. Reciprocating pumps are one of the main vacuum equipment to obtain crude vacuum. Widely used in chemical, food, building materials and other departments, especially in the vacuum crystallization, drying, filtration, evaporation and other processes is more appropriate. Rotary vane vacuum pump for one of the basic equipment in addition to pumping gas airtight container. It may be used alone, or as a booster pump, diffusion pump, turbo pump foreline gas pump filters. This type of gas station pump is widely used in metallurgy, machinery, electronics, chemicals, petroleum, pharmaceutical and other industries vacuum smelting, vacuum coating, vacuum heat treatment, vacuum drying and other processes. Rotary vane vacuum pump has a compact structure, small size, light weight, low noise, vibration and so on. Therefore, it is suitable for use as diffusion pump before the pump, but also applies to the use of precision instruments and laboratory support. For example: a mass spectrometer, refrigerator assembly line, vacuum freeze-drying machine. Rotary vane vacuum pumps can be operated in any inlet pressure, has been widely used in food vacuum packaging, vacuum forming plastics industry. Conveying the printing paper industry, vacuum chuck, vacuum suction and the like.
