Air Cooled Dry Screw Vacuum Pump LG-70

 Product DescriptionDry screw vacuum pump, is the use of a pair of screw, made in the pump shell synchronous high-speed reverse rotation of the effects of the suction and exhaust and suction device, two screw fine dynamic balancing correction, and is supported by bearings, is installed in the pump shell, between screw and screw has a certain gap, so the pump work, no friction between each other, smooth running, low noise, Working chamber without lubricating oil, therefore, dry screw pump can remove a lot of steam and a small amount of dust gas occasions, higher limit vacuum, lower power consumption, energy saving, maintenance-free and other advantages.Our AdvantagesThere is no medium in the working chamber, which can obtain a clean vacuum.. No clearance between rotating parts, high speed operation, small overall volume.There is no compression in the gas, suitable for extraction of coagulable gas.Can remove a lot of steam and a small amount of dust gas occasions.. High vacuum, the ultimate vacuum up to 1 Pa.Screw material is high strength special material, material density, wear resistance, stable performance.No friction rotating parts, low noise.. Simple structure, convenient maintenance.Wider range of use: corrosive environment can be used.No oil consumption, no water.Pump gas directly discharged from the pump body, no pollution of water, no environmental pressure, more convenient gas recovery.It can be composed of oil-free unit with Roots pump and molecular pump. Typical Use------Oil and gas recovery.    ------Biological medicine ------Food Processing ------ Single crystal furnace------Vacuum forming ------Vacuum flame refining ------Electronic photovoltaic. ------Semiconductor synthesisProduct ParametersType                                                                            Basic parametersPumping speedm3/hPresure limit(Pa) Power (kW) revolution (rpm)Inlet calibermmoutlet caliber mmCooling water volumeL/minnoise dB(A)Overall dimension(length*width*height)mmLGV-18018054290040402< 781157x375x734LGV-25025055.5290050405.5
