The Roots vacuum pump is a rotary positive displacement vacuum pump without internal compression, also known as a mechanical booster pump. It is an ideal vacuum obtaining device for quickly removing gas from a closed container. When used in the field of vacuum engineering, it is generally connected with a liquid (water) ring vacuum pump, a gas-cooled Roots vacuum pump, an oil rotary vacuum pump, a dry vacuum pump, etc. to form a vacuum unit system. Widely used in electronics, chemical, pharmaceutical, metallurgical, food, textile, environmental protection and other industrial fields.
Specialties
◆ High pumping suction speed within the widely pressure range ( suction speed-30~20000L/s), it will improve the suction speed and ultimate vacuum speed as a " accelerator"
◆ It is quick start.
◆ the pump chamber of Roots vacuum pumps is free of any sealing agents or lubricants. It is insensitive in the dust and vapor, which can keep the cleaning vacuum.
◆ The absence of reciprocating masses also affords trouble-free dynamic balancing, which means that Roots vacuum pumps operate extremely quietly in spite of their high speeds
◆ In the Roots vacuum pump, two synchronously counter-rotating rotors rotate contactlessly in a houseing, running smoothly, reliable.
◆ There is no friction in the suction chameber , a Roots vacuum pump can be operated at high rotation speeds, low power usage.
◆ No need the exhaust valve
◆ The gas in the pump flow by vertically, it is good to remove the dirty and condensate from the gas.
◆ Compact design, low current consumption, low operation and maintenance costs.
