Roots vacuum pump is a positive displacement pump, also known where the best mechanical booster pump Roots, the advantage is with high pumping speed at low inlet pressure, is currently available in a high vacuum pump of the main One. Roots vacuum pressure differential is not allowed to work, otherwise it will overload or overheating and damage, and therefore must use a reasonable selection of Roots vacuum pump pre-install the necessary protective equipment. 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, a small mechanical friction loss, so the drive power is small. 5, easy to maintain and repair Roots vacuum where the best, low-cost, high-life. 6, can be exhausting condensable gases. BZJ series multi-stage Roots pump main features: 1, no oil and water pumping Roots vacuum chamber where the cheapest, no secondary pollution; 2, with two single-stage pump series compared to compact Roots vacuum pumps, small footprint; 3, fewer parts, easy maintenance and repair, reducing the cost Roots vacuum supply price _ _ Zhucheng East Han Machinery Co., Roots vacuum provided by the East Han Machinery Co., Ltd.
