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 noise control Roots vacuum pump manufacturers, pump muffler. BZJ series two-stage Roots pump main features: 1, no oil and water pumping chamber, no secondary pollution; 2, with two single-stage pump series Roots vacuum compared to where the best, compact, space small; 3, fewer parts, ease of maintenance and repair, reduces the cost; 4, internal connection between the level of the vacuum chamber, reducing the amount of leakage between the two pump connection piping, improves the performance of unit; 5, the internal structure Roots vacuum phone manufacturers to optimize and improve the efficiency of the vacuum pump, reducing power consumption; 6, the control system of the entire unit is more simple and convenient; 7, reducing the unit auxiliary fittings, more conducive to the production and maintenance of the unit where the Roots pump Preferably, the Roots vacuum pumps, Zhucheng East Machinery Co., Ltd. is provided by John Han Machinery Co., Ltd.
