Overview
JR series of oil-free screw vacuum pump, is my company's independent research and development of advanced dry vacuum pump. Because the screw vacuum pump without oil lubrication or water seal, pump cavity completely oil-free, so compared to the traditional water ring vacuum pump, rotary vane vacuum pump, slide valve vacuum pump, reciprocating vacuum pump and water jet vacuum pump has unparalleled advantages,
Both energy-saving emission reduction, and low-carbon environmental protection, vacuum industry is a new trend.

Performance characteristics
1. Pump cavity without oil, no pollution to the vacuum system, improve product quality.
2. Pump oil without oil, to solve the oil emulsion and frequent replacement of working fluid, frequent maintenance and maintenance issues, saving the use of finished products.
3. Dry run, will not produce waste oil and fumes, it will not produce waste water, is conducive to environmental protection, saving oil resources and water.
4. Extreme vacuum up to 5Pa, or even higher, and Roots pump, molecular pump in series can be composed of oil-free unit.
5. Can remove the gas containing a lot of water vapor and a small amount of dust.
6. With anti-corrosion coating treatment, can remove a variety of corrosive media, especially for chemical, pharmaceutical products in the distillation, drying, degassing and so on.
7. The pump is directly discharged from the pump, no water and oil pollution, gas solvent recovery more convenient.
8. Easy to clean, such as the pump into the dirt to be cleaned only need to open the pump suction port, open the pump after the pump from the suction port by adding the right amount of water or cleaning agent, you can clean the pump, Remove the entire pump.

Application scope
1. Chemical, pharmaceutical: product distillation, drying, degassing, material handling and so on.
2. Electrical: Transformers, transformers, epoxy resin vacuum casting, vacuum vacuum oil immersion, vacuum pressure impregnation.
3. Industrial furnace: vacuum brazing, vacuum sintering, vacuum annealing, vacuum pressurized gas quenching, vacuum dewling and so on.
4. Aviation, aerospace: spacecraft carrying spacecraft orbit, return capsule, rocket attitude adjustment cabin, space suit, astronaut space out of space, airplane and other vacuum simulation experiments.
5. Vacuum coating: vacuum evaporation coating, vacuum magnetron sputtering coating, film winding continuous coating, ion plating and so on.
6. Metallurgy: special steel smelting, vacuum induction furnace, vacuum desulfurization, degassing.
7. Drying: pressure vacuum drying, kerosene gas drying, wood drying, frozen vegetables and other food.
8. Other situations where vacuum is required.
