Vacuum pump unit
Vacuum unit classification:
Water-ring atmospheric jet pump unit, water-ring vacuum unit, Roots water-ring vacuum unit, Roots corrosion-resistant water-ring vacuum unit, vacuum pump station (water-ring negative pressure device), water-ring vacuum pump closed-loop system, etc.
Rotary vane vacuum unit is widely used in chemical industry, food sublimation drying, high altitude simulation test and other vacuum systems.
Rotary vane vacuum unit is mainly composed of pump and rotary pump. Rotary vane pump is selected as the front-stage pump in the rotary vane vacuum unit, so it overcomes the shortcoming of low pumping rate when the rotary vane pump is used at a certain pressure, and retains the advantages of Roots pump which can work quickly and has a relatively large pumping rate. Because of its compact structure, large pumping speed and small area, it can replace many mechanical vacuum pumps. Therefore, the rotary vane pump unit is widely used in vacuum smelting, power capacitors, transformer vacuum heat treatment, vacuum coating equipment pre-pumping, electro-vacuum semiconductor and other industries to remove oxygen from sealed vessels is not high. No explosive, no corrosive to metal, no chemical reaction with pump oil, and no gas containing particulate dust.
The vertical oil-free reciprocating pump unit is composed of ZJ pump as the main pump and oil-free pump as the front pump in series. Because the vacuum pump adopts oil-free self-lubrication system, a clean vacuum can be obtained. In this way, after installing the tail gas collection device, the gas that can not be solidified and collected can not be compressed in the high vacuum system can be collected and avoided at the same time. The problem of polluting the environment caused by the discharge of large quantities of waste water generated by the water ring unit is avoided.
