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 Henan Roots pump prices, poor pumping hydrogen; (3) the shape of the rotor surface for a more complex curve cylinder more difficult 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. ZJ / ZJB Roots vacuum pump is a positive displacement pump Henan Roots vacuum outlets, which uses a pair of eight-shaped rotor Roots vacuum Henan phone manufacturers, for isokinetic reverse rotation in the pump housing to produce suction and discharge gas effect. ZJB belt relief ZJ Roots Roots vacuum pump is derived product, ZJ Roots pumping principle is the same except that the pump intake and exhaust passages provided and installed in the channel automatic overload protection valve, the intake air vent pressure difference is always controlled and reliable operation of the pump to allow the maximum pressure difference between the inside.
