Oil-free vacuum pump rotary vane vacuum pump series, is a kind of mechanical vacuum pump can work without any oil for lubrication. It has the advantages of simple structure, easy operation, convenient maintenance and no environmental pollution. Oil-free vacuum pump durability, is a vacuum, compression, dual-use vacuum pump, is a wide range of applications to obtain a basic vacuum equipment. Oil-free vacuum pump works: It works and the same general volume pump, the stator, rotor, rotary vane, cylinder, motor and other major components. Rotor with a rotating plate, eccentrically installed in the fixed cylinder, when the rotor rotates at high speed, the rotor slot within the four radial sliding rotary pump chamber will be separated into four studio, due to centrifugal force, the vane close to the Cylinder wall, the stator into the discharge port separated from the cycle of operation, for the varactor, the inhalation of gas, discharged from the exhaust port, so as to achieve the purpose of pumping. Oil-free vacuum pump can be used in the following tasks: 1. Automatic packaging line vacuum suction line open bags, loading. 2. Printing machinery on the vacuum suction paper. 3. A variety of liquid into the bottle of high-efficiency vacuum filling. 4. All kinds of plastic vacuum plastic forming. 5. Object surface in airtight vacuum test. 6. Carton and bottles of the standard vacuum suction paste paste. 7. Vacuum to attract the fixed photographic plate. 8. Use of pressure differential to guide gas analysis under vacuum. 9. A variety of medical machinery supporting the use of online. 10. Processing of non-magnetic parts folder with a vacuum chuck fixture. 11. A variety of containers in the vacuum leak test. 12. Food processing machinery on the application. 13. Chinese and Western medicine factory vacuum distillation and drying. 14. Hospital operating room vacuum to attract. 15. Institutions, research institutes, factories and mines laboratory gas analysis, physical and chemical experiments. 16. A variety of medical equipment supporting the use of such.
