King of the pump ---- Rotary vane vacuum pump

Lead: rotary vane vacuum pump products have the following performance characteristics, so as to achieve pollution, and save resources. 1. The vacuum unit is a complete dry system with no pollution to the drawn media. 2. It is insensitive to the environment in which the drawn media has water vapor or dust. Compared with the double-stage rotary vane vacuum pump, the advantage is obvious. 3. No Oil rotary vane vacuum pump can be used anti-corrosion treatment, can be extracted a variety of corrosive media, especially for chemical, pharmaceutical products distillation, drying, degassing, etc .; 4 dry run, will not waste oil and Fumes, will not produce waste water, is conducive to environmental protection, saving oil resources and water; 5. Single laboratory rotary vane vacuum pump that can reach 6. The entire unit maintenance and cleaning convenience, due to the pump cavity workpiece without contact, do not wear all year round Use the vacuum performance is basically the same; 7. Exhausted gas is directly excluded pump, water and oil pollution, gas, solvent recovery convenience. First, the rotary vane vacuum pump Product Overview Rotary vane vacuum pump is divided into 2XZ rotary vane vacuum pump 2xz 4 rotary vane vacuum pump and 2x rotary vane vacuum pump, the performance of its direct-connected vacuum pump from high-pressure level and low pressure Grade two parts, rotary vane vacuum suction inlet and vacuum equipment connected to the operation of the container a large number of gas inhalation and discharge. When the equipment gets a vacuum, the high-pressure stage exhaust valve will be closed and the high-pressure stage sucked gas will be delivered to the second stage and a second vacuum will be drawn in and out of the vacuum unit. Pump and motor with shaft, high speed, small size, compact structure, easy to work with mobility, special use of metal scraper for diffused pump pump, precision instruments supporting and use, used in medicine, food packaging, electronics Other units to use. Second, rotary vane vacuum pump selection elements: 1, rotary vane vacuum pump flow, lift, self-priming height; 2, rotary vane vacuum pump supporting power, voltage; 3, rotary vane vacuum pump inlet and outlet diameter, over-flow medium. Third, the rotary vane vacuum pump principle Pump mainly by the pump body, rotor and rotary parts and other components such as: 2x 30 rotary vane vacuum pump, 2x 8 rotary vane vacuum pump. Eccentricity in the pump body cavity fitted rotor, the rotor slot installed two rotary blade, due to the spring force and the centrifugal force generated by the rotation of the rotor blade cavity wall, the pump body into the exhaust only by the rotor and the rotor Separated into two parts, the rotor rotates in the cavity, the intake part of the gradual expansion of the volume of the chamber while inhaling gas, while gradually compressing the volume of the exhaust part of the inhalation of compressed gas discharged from the exhaust valve, so as to achieve the purpose of pumping .

No oil and less oil work. In the pumping system and rotary vane vacuum pump should be installed at the vacuum valve should be closed before shutting down the channel has been to prevent the vacuum from the pump back to the pumping system! Ensure pumping system is non-corrosive gas; 2) Do not switch to other types of oil. Must use a professional vacuum oil. Always check the oil level position, do not meet the requirements must be adjusted to meet the requirements. In the operation of the vacuum pump, the oil level to the center of the oil standard shall prevail; 3) Regularly check the oil quality and found that the vacuum oil emulsion and deterioration of the timely replacement of vacuum oil to ensure that 2X-4 rotary vacuum pump is working; 4) Term, according to the actual conditions of use and ability to meet the performance requirements and other considerations, by the user discretion. General 2x series rotary vane vacuum pump, pumping clean and dry gas, it is recommended to change oil about 100 hours. 5) Under normal circumstances, rotary vane vacuum pump after 2000 hours of work should be carried out overhaul, check the rubber seal aging, check the exhaust valve is whether or not Crack, clean the valve plate and exhaust valve seat dirt. Clean the entire vacuum chamber components, such as the rotor, rotary vane, springs and so on. General use of gasoline cleaning, and drying. Rubber parts after cleaning with a dry cloth accessories can be dry. Cleaning assembly should be gently, be careful bumps; 6) the same conditional cleaning of the pipe to ensure smooth piping. 7) after reassembly, should be commissioned, usually no load, idling for 2 hours and change the oil twice. As in the cleaning process, the rotary vane vacuum pump will remain a certain amount of volatile material in the box, to be volatilized finished, and then put into normal work; 8) Check the rotary vane vacuum pump piping and joints are loose, leak phenomenon . Turn the vacuum pump by hand to see if it is flexible. Nine, Xiaobian Comment: precisely because of the advantages of rotary vane vacuum pump stored in the fluid machinery, especially the oil-free vacuum pump, rotary vane vacuum pumps and other direct access to the industry in the environmental aspects of cognition, its natural widely used in various fields: 1. Chemicals, pharmaceuticals: product distillation, drying, degassing, material handling, etc. 2. Electricians: transformers, transformers, epoxy vacuum casting, vacuum impregnation capacitors, vacuum pressure impregnation; 3. Aerospace: spacecraft Spacecraft, astronaut spacecraft, spacecraft and other vacuum simulation experiments; 4. Vacuum coating: vacuum evaporation coating, vacuum magnetron sputtering coating, film winding continuous coating, Ion plating, etc .; 5. Industrial furnace: vacuum brazing, vacuum sintering, vacuum annealing, vacuum pressurized gas quenching, vacuum antelope, etc .; 6. Drying: kerosene vapor phase drying. Because pharmaceutical companies do not meet the environmental standards caused by the shutdown, even as a result of illegal sewage pollution caused by environmental pollution incident often seen in the newspapers.
