Roots vacuum pump (referred to as: Roots pump) is built with two opposite directions pump synchronous rotation of the rotor Roots vacuum leaf between the rotor, the rotor and the pump housing walls there is a small gap varactor do not touch the vacuum pumps. Roots vacuum in the oil, chemicals, plastics, pesticides, turbine rotor balancing, aerospace simulation and other devices have been long-running test, so it should be vigorously promoted and applied in the country. But also widely used in petroleum, chemical, metallurgy, textile and other industries. Vacuum accessories for use in vacuum noise control, vacuum muffler. Roots pump is characterized by: 1. The rotor and the pump chamber, between the rotor and the rotor has a certain gap, do not touch, does not require oil lubrication. 2. The rotor has a good geometrical symmetry can improve the speed, which can produce a compact, high pumping speed pump. 3. Pump vibration small price Roots vacuum, where a large volume of Roots vacuum best volume utilization factor = 0.5. 4. Does not occur in the pump chamber as a mechanical vacuum pump as compression and, therefore, it does not need to vent. That is why, in addition to pumping condensable vapors. 5. Start fast, able to reach the ultimate vacuum in a short time. Low power, low operation and maintenance costs. 6. When the Roots pump over a wide pressure range (1000Pa ~ 1Pa) has great speed where Roots vacuum pump can quickly exhaust a sudden release of gas, make up the diffusion pump and mechanical seal pumps (1000Pa ~ 1Pa) pumping Speed ??is very small defect. Therefore, it is most suitable for use booster. Roots vacuum outlets, Roots vacuum pumps, Zhucheng East Machinery Co., Ltd. is provided by John Han Machinery Co., Ltd. Zhucheng East.
