Rotary vane pumps Features 1. Small size, light weight, low noise; 2. the town has a gas valve, pumping a small amount of water vapor; at an ambient temperature of five degrees Celsius at forty degrees Celsius, the air inlet pressure is less than 1.3X103 Pa under conditions permitting long-term continuous operation, has been pumping gas relative humidity greater than ninety percent of the time, it should open the gas ballast valve. 3. With automatic anti-return oil valve, easy start; 4. continuous flow air intake port operation shall not exceed one minute; 5. Not available for pumping corrosive to metal rotary vane pumps picture, to pump oil from a chemical reaction, the gas containing dust particles, as well as high oxygen, explosive, toxic gases. XD type rotary vane vacuum pump features 1, XD type rotary vane vacuum pump can be operated at any inlet pressure, the biggest feature. 2, inside the XD type rotary vane vacuum pump oil mist eliminator can effectively eliminate the gas pump discharge oil mist, mist avoid contamination of the surrounding environment. 3, the XD-type rotary vane vacuum pump suction port is equipped with a check valve rotary vane pump, when the pump is stopped when the combined effects of internal check valve and pump specifically set hole, immediately pump with pumped system isolation prevent pump oil is pumped back into the system, while maintaining the true width of the container is drawn, thus the use of this type of pump do not need to configure the ocean can vacuum shut-off valves with deflation, which can reduce the use of user fees. 4, XD type rotary vane vacuum pump with oil separator, which together form the mist eliminator effectively silencing system can eliminate exhaust noise and prevent noise pollution. 5, XD type rotary vane vacuum pump and is directly coupled motor mount, using air cooling, no water cooling pipes, so this model is a compact rotary vane pumps, easy to install equipment. 6, reasonable structure, small vibration, no bolt can work.
