【Vacuum pump operation guide】 Rotary vane vacuum pump operation
1. Check the oil level, to stop pumping oil to the oil standard center is appropriate. Too low on the exhaust valve can not play the role of oil seal, affecting the degree of vacuum. Too high, may cause the air to start when the fuel injection. Operation, the oil level has increased, is a normal phenomenon. The oil is supplied with a clean vacuum pump oil of the specified grade and is added from the filler hole. After refueling, should be screwed on a plug. The oil should be filtered to prevent debris from entering and clogging the oil hole.
2.2RS Series Rotary vane vacuum pump can be activated in the air or any vacuum. Pump port, such as the installation of solenoid valve, should be synchronized with the pump action.
3. When the ambient temperature is too high, the temperature of the oil increases, the viscosity decreases, and the saturated vapor pressure increases, causing a decrease in the ultimate vacuum, especially the total pressure measured by the thermocouple. Such as enhanced ventilation and cooling, or improved pump performance, the ultimate vacuum can be improved.
4. Check the 2RS series rotary vane vacuum pump limit vacuum to compressed mercury vacuum gauge shall prevail, such as the full pre-pumping check, the pump temperature to stabilize the pump and the meter directly connected to run within 30 minutes, will reach the ultimate vacuum The The total pressure measured value and pump oil and vacuum gauge, regulatory error, sometimes the error can be very large, only for reference.
5. Such as the relative humidity is high, or by pumping gas containing more condensable steam, connected to the container, it is appropriate to open the gas valve, running 20 to 40 minutes after closing the gas valve. Before stopping the pump, the valve can be opened for 30 minutes to extend the life of the pump oil.
6.2RS series rotary vane vacuum pump oil selection: pump oil viscosity of the starting power and pump limit vacuum, high viscosity when the vacuum is favorable, the starting power is larger. The saturated vapor pressure of the oil at the pump temperature will affect the total pressure of the pump, the lower the better.
