Roots vacuum structural features (1) the pump chamber without compression, no exhaust valve. Simple and compact structure, to be pumping gas in the dust and water vapor is not sensitive; (2) a relatively low compression Roots vacuum where the best of the hydrogen pumping poor; (3) the shape of the rotor surface for a more complex curve difficult cylinder, machining and inspection. Roots vacuum at home and abroad in recent years has been rapid development. In refining, petrochemical, electrical, electronics and other industries has been widely used. Two leaves ZBK series Roots vacuum pump is a rough vacuum equipment of vacuum pumps Roots wholesale, compared with the water ring vacuum pump with high efficiency Roots vacuum where the cheapest, small size, light weight, energy-saving features significantly its power consumption is only about 50% of water ring vacuum pump electricity, so the vacuum dehydration has been widely used in papermaking, food, chemicals, clothing, sugar and other industries as well as the use of the cigarette industry's aspiration. Pumping medium can be dry, wet air or gas-water mixed gas but the media can not contain particulate solids.
