2XZ direct rotary vane vacuum pump working principle and precautions
2XZ type direct rotary vane vacuum pump with small size, light weight, low noise, easy to start and so on. Now we introduce the working principle and precautions of 2XZ direct rotary vane vacuum pump. 2XZ direct rotary vane vacuum pump 2XZ direct rotary vane vacuum pump Working principle 2XZ direct rotary vane vacuum pump is a two-stage high-speed direct-coupled rotary vane vacuum pump, which is eccentrically mounted in the pump chamber Rotor, rotor and rotor within the slot. When the rotor drives the rotary vane to rotate, the vane is closely attached to the cavity wall to separate the inlet and the outlet, and the volume of the intake cavity is periodically expanded to be inhaled while the volume of the exhaust cavity is periodically reduced Compress the gas and push the exhaust valve off to get the vacuum. Second, 2XZ type straight rotary vane vacuum pump Notes 1. Direct rotary vane vacuum pump to check the oil level, to stop the pump oiling to the oil standard center is appropriate. Too low of the exhaust valve can not play the role of oil seal, affecting the degree of vacuum; too high, may lead to the start of the atmosphere when the fuel injection. Operation, the oil level has increased, is a normal phenomenon. Direct vacuum pump oil using the provisions of the clean vacuum pump oil, oil from the hole to join, after the fuel is completed, should be screwed on a plug, the oil should be filtered to prevent debris from entering, blocking the hole. 2. Direct rotary vane vacuum pump in the atmosphere or any vacuum for a start. Pump port, such as attached solenoid valve, should be with the pump at the same time action. 3. Ambient temperature is too high, the oil temperature increases, the viscosity decreases, the saturated vapor pressure will increase, will cause the ultimate vacuum decreased, especially with the thermocouple measured total pressure. Such as to enhance ventilation and cooling, or to improve the performance of the straight rotary vane vacuum pump, the ultimate vacuum can be improved. 4. Check the direct vacuum rotary vane vacuum limit vacuum mercury vacuum gauge shall prevail, as measured by the full pre-pumping calibration, the pump temperature reached a steady, direct rotary vane vacuum pump port and meter directly connected to the operation within 30 minutes , Will reach the ultimate vacuum. The total pressure gauge measured value and pump oil and vacuum gauge, the regulation error, and sometimes the error can be very large, only for reference. 5. Direct rotary vane vacuum pump, such as high relative humidity, or pumping gas containing more condensable steam, connected to be pumped container, the gas valve should be open, 20 to 40 minutes after operation turn off gas ballast valve. Stop direct rotary vane vacuum pump before the open air valve can be open for 30 minutes to extend the life of pump oil.
