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. In order to improve the ultimate vacuum pumps, vacuum pumps Roots price, Roots 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 v0 between the rotor and the casing, and then is discharged through the exhaust port. Because after breathing v0 space is completely closed state, so where's the best Roots vacuum, 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, 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, maintaining a certain clearance Roots vacuum pumps, can achieve high speed operation. Uses and Features: ZBK series Roots vacuum pump is a rough vacuum equipment, it is widely used in papermaking, chemical, pharmaceutical, building materials, packaging, egg tray, food, clothing, sugar and other industries, is a long rotary Ministry absorbent paper industry box or Fourdrinier paper machine wire section ideal for tank suction vacuum dehydration. ZBK series Roots vacuum pump compared with liquid ring vacuum pump in this range, with a pumping speed, high efficiency, compact structure, small size, easy maintenance, long life and low power consumption.
