Vacuum pumps use mechanical, physical, chemical, physical and chemical methods such as container extraction, access and maintenance of vacuum equipment. Vacuum pumps and other equipment (such as vacuum vessels, vacuum valves, vacuum measuring instruments, connecting pipes, etc.) form a vacuum system and are widely used in the electronics, metallurgy, chemical, food, machinery, medicine, aerospace and other sectors. Vacuum pump classification has the following nine kinds 1, W reciprocating pump (valve vacuum pump W-type) is one of the major vacuum equipment to obtain rough vacuum. Widely used in chemical, food, building materials and other departments, especially in the vacuum crystallization, drying, filtration, evaporation process is more appropriate. 2,2X rotary vane vacuum pump (double vane vacuum pump) One of the basic equipment for the closed container extraction of gas. It can be used alone as booster pump, diffusion pump, molecular pump before use. This type of pump is widely used in metallurgy, machinery, electronics, chemicals, petroleum, pharmaceutical and other industries vacuum smelting, vacuum coating, vacuum heat treatment, vacuum drying process. 3, rotary vane vacuum pump 2XZ (Model2XZ vane vacuum pump) compact structure, small size, light weight, low noise, vibration and so on. Therefore, it applies to the foreline pump, but also for supporting the precision instruments and laboratories use diffusion pump. For example: mass spectrometry, refrigerator production line, vacuum freeze-drying machine. 4, rotary vane vacuum pump (model Xd vane vacuum pump) can withstand the work pressure in any project has been widely used in food vacuum packaging, vacuum forming plastic industry. Transfer printing industry, vacuum fixtures, vacuum and so on. 5, SK series water ring vacuum pump (Shenzhen water ring vacuum pump) is mainly used for rough vacuum. A lot of process gas. It is mainly used for pumping air and other non-corrosive, water-insoluble, solid particles containing a small amount of gas to form a vacuum in a sealed container. Absorb gas mixed with liquid small allowable amount. It is widely used in machinery, pharmaceuticals, food, petrochemical and other industries. 6, 2SK, 2SK - P1 series of two-stage water ring vacuum pump (Model 2SK, 2SK-P1 water ring vacuum pump) is mainly used for pumping air and other corrosive, insoluble in water, allowing a small amount of gas containing solid particles. Widely used in food, textile, pharmaceutical and vacuum evaporation, condensation chemical, soaking, drying and other processes. Vacuum pump with high, simple structure, easy to use, reliable, easy maintenance. 7, JZJS Roots - water ring pump unit (model JZJS Roots water ring vacuum pump system) as a result of the former for the pump, especially the extraction of a suitable water ring pump unit, thus containing water vapor and corrosive and condensable gases The process of mass. Such as: vacuum distillation, evaporation, dehydration, crystallization, drying process. 8, JZJX Roots rotary vane pump unit (Model JZJX Roots vacuum pump vane system) Roots pump is the main pump, the pump before the series of rotary vane pump. Compact structure, easy to operate. For pumping air and other non-condensable and non-corrosive gases, widely used in the need for large pumping speed and high vacuum, so that the system. Such as: vacuum smelting, power capacitors, transformers, vacuum impregnation, vacuum coating equipment, pre-pumping and so on. 9, ZJ series Roots vacuum pump (ZJ Roots vacuum pump) is a rotating positive displacement pump, the pressure to be with the front pump will be used in a wider range of pumping speed than the gas range is not sensitive to dust and water vapor Caused widespread use in metallurgy, chemicals, food, electronic coatings and other industries.
