Rotary Piston Vacuum Pump

Rotary piston vacuum pump is suitable for air and other ordinary gases, with a gas ballast valve, witch could be applied topump condensable gases (such as vapor). The pump should be equipped with appropriate accessories if thegas pumpedhas the following features, such as rich in oxgen, explosive, corrosive to ferrous metal and chemical reactive with the vacuum pump oil. This series of pumps could be operatedin single unit or act as the pre-process pumping unit for the next high vacuum pumps, such as diffusion orroots pumps. It is widely used in the industries of vacuum coating, vacuum heat treatment, vacuum impregnation, vacuum smelting, vacuum metallurgy, vacuum drying,molecular distillation and altitude simulation testing. Features: * origin products-based, optimized design, easy for maintenance and repair; * the original 3-cylinder mechanism has been improved to a upgraded 2-cylinder one, convenient for maintenance and repair; side cover on the cylinder body for a convenient cleaning operation to the long and short cylinders; * oil circulation system equipped with auto control operation mechanism, needn't bother to cut off the oil input valve after the machine turning off; * altered the bearing position a bit outside so elongated its service life; * with a protective shaft sleeve, quite reduced the wearing out of primary shaft; * after elaborate dynamic poise adjustment to rotary parts, ensureda stable running and low noise performance; HG2H Performance parameter Modle
