Roots vacuum pump in addition to the limit depends on the structure and manufacturing precision pump itself, but also depends on the ultimate vacuum pump before. To improve the ultimate vacuum pumps, vacuum pumps can be used in tandem. Roots pump works with the Roots blower similar. Due to the continuous rotation of the rotor, gas is drawn from the intake port into the space between the rotor and the casing where the best v0 Neiluo Ci vacuum, and then discharged through the exhaust port. Because after breathing v0 space is completely closed state, so there is no gas in the pump chamber compression and expansion. But when the top edge of the rotor turned vent, when v0 space communicates with the exhaust side of the Roots pump, due to the high side of the exhaust gas pressure, then rushed back to some of the gas space v0 in order to enable gas pressure suddenly increased. As the rotor continues to rotate, the gas is discharged out of the pump. Roots pump in the pump chamber, there are two "8" shaped rotor mounted perpendicular to each other on a pair of parallel shafts Roots vacuum outlet, by a gear ratio of a pair of synchronized reverse gear drive for the rotational movement to each other . Between the rotor, between the rotor and the casing inner wall Roots vacuum use, maintaining a certain clearance, can achieve high speed operation. Roots vacuum Main features:? High speed, high volumetric efficiency. ? Simple structure, operation, and maintenance. ? Rotor is locked, no axial string action phenomenon. ? High-precision transmission gear and a good dynamic balance, low noise, smooth operation. ? Pump chamber for oil-free structure, applicable to the general air extraction and various special gases. ? Compared with other mechanical vacuum pump, energy-saving effect is remarkable. ? Before the pump can be used with all kinds of facilities, can be widely used in various processes range. ? Can be cooled and water-cooled to meet the requirements of different operating conditions. Roots vacuum use, Zhucheng East Han Machinery Co., Roots vacuum provided by Zhucheng East Han Machinery Co.
