ZJ series Roots vacuum pump is a rotary positive displacement pumps, must have before the pump with before use, in a wide range of pressures greater Roots vacuum pumping speed Hebei manufacturer, was pumping gas for insensitive to contain dust and water vapor, is widely used in metallurgy, chemical, food, electronics and coatings industries. Gas-cooled Roots pumping through both a plum-type rotors, alternating suction and discharge gas to form a vacuum, face contour shape of the rotor includes a lot of curves, such as white lines and arcs cycloid Roots vacuum pumps, as well as the arc, including lines, rotor and between the rotor between the rotor and pump a certain gap, do not touch, smooth rotation Hebei Roots vacuum use, is stable and smooth pumping exhaust gases to the estuary, the use of three petals type rotors, can ensure air return port can never communicate with the inlet, so that when the pump is working under high pressure differential Hebei Roots pump price of gas can be discharged through the cooler return after the pump cooling pump rotor, without affecting the vacuum The ability to move the motor through V-belt or coupling drive pump. 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.
