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 vacuum pump (referred to as the Roots pump) is a rotary positive displacement pumps. It is evolved from the Roots blower. Depending on the scope of work Roots vacuum pump, is divided into vertical atmospheric low Roots vacuum pump; Roots vacuum pump (also called mechanical booster) and high vacuum multi-stage Roots pump. In general, the Roots pump has the following characteristics: in a wide pressure range greater pumping speed; starting fast, able to work immediately; not sensitive to dust and water vapor contained in the gas to be drawn; the rotor does not have to lubricate Henan Roots pump prices, oil-free pump chamber; vibration, rotor balancing Henan Roots vacuum conditions better direct, no vent; Nan Luoci Creek Drive power vacuum manufacturers, small mechanical friction losses; compact, accounting land area is small; low operation and maintenance costs. Therefore, Roots pump in metallurgy, petrochemical, paper, food, electronics industry has been widely used.
