Roots vacuum Main features: 1, in a wide pressure range (1 ~ 1 × 10 4pa) have relatively the pumping speed. 2, the pump chamber without oil, to avoid contamination of the oil vapor vacuum system. 3, small vibration, low noise. 4, mechanical friction losses Creek Nan Luoci pump manufacturer, so drive small power. 5, easy to maintain and repair, low cost, high life. Roots vacuum pump (referred to as the Roots pump) is a non-rotating inner compression variable capacity pump. Is the use of two 8-shaped rotor is rotated in the pump housing for generating suction and discharge action. The principle is similar and Roots blower. Because of its work in the low pressure range, a large free path of gas molecules Roots vacuum pump, the gases lose a great resistance Henan small gap Roots vacuum use, which can obtain a higher compression ratio, can be used as a booster pump; but it alone can not put gas directly into the atmosphere to the needs and pre-vacuum pumps used in tandem, was pumping gas through the front stage vacuum pump into the atmosphere to go.
