Introduction Of Two Stage Rotary Vane Vacuum Pump
2XZ series two stage rotary vane vacuum pump can be used alone or as a backing pump for booster pumps, diffusion pumps, molecular pumps and titanium pumps. And for electronic device manufacturing, vacuum drying, filtration, welding, metal smelting, etc.
Two Stage Rotary Vane Vacuum Pump Working Principle:
A two stage rotary vane vacuum pump consists of a cylindrical chamber with a rotor fitted with multiple vanes. As the rotor spins, vanes slide in and out of the rotor slots, creating chambers of varying volumes to collect and release gases.
As the vanes rotate, gas is drawn into the pump through the intake port and compressed as it moves toward the discharge port. The compressed gas is then expelled through the exhaust port, leaving a low pressure or vacuum environment in the chamber. The body is discharged from the pump. This leaves a low pressure or vacuum in the chamber, drawing more gas through the inlet.
Two Stage Rotary Vane Vacuum Pump Features:
Efficient suction capacity:
These pumps are capable of generating high vacuum levels and have high pumping speeds, making them ideal for a wide range of applications.
Low noise and vibration:
The two stage rotary vane vacuum pump is relatively quiet and generates minimal vibration during operation, making it suitable for use in environments where noise and vibration are of concern.
Oil lubrication:
Most two stage rotary vane vacuum pumps use oil to lubricate the vanes and seal the chamber, which helps extend the life of the pump and ensures efficient operation.
Pollution Resistance:
The oil used in these pumps also helps prevent contamination of the pumped gas or fluid, which is important in applications where purity is critical.
Easy to control:
Rotary vane vacuum pumps are easy to control and can be adjusted to meet the specific requirements of different applications.
Small and portable:
These pumps are usually small and light, making them easy to move and install in different locations.
Application Of Two Stage Rotary Vane Vacuum Pump
Two stage rotary vane vacuum pumps can be used in a wide range of applications, including analytical instruments, vacuum coating, semiconductor manufacturing, etc., and are commonly used in various industrial, scientific, and laboratory applications to generate vacuum.
Operation Use:
- The pump can be started once under the atmosphere or any vacuum degree.
- When the ambient temperature is too high, the temperature of the oil will rise, the viscosity will drop, and the saturated vapor pressure will increase, which will cause a decrease in the ultimate vacuum, especially the total pressure measured with a thermocouple meter. If the ventilation and heat dissipation are enhanced, or the performance of the pump oil is improved, the ultimate vacuum can be improved.
- Check the ultimate vacuum of the pump based on the compressed mercury vacuum gauge. If the pre-pumping has been fully calibrated, the pump temperature is stable, the pump port is directly connected to the gauge, and the ultimate vacuum will be reached within 30 minutes of operation. The value measured by the total pressure gauge is related to the errors of the pump oil, vacuum gauge, and regulation, and sometimes the error may even be large, so it can only be used as a reference.
- If the relative humidity is high, or the pumped gas contains more condensable steam, it is advisable to open the gas ballast valve after connecting the pumped container, and close the gas ballast valve after 20-40 minutes of exercise.
Maintenance:
- The two stage rotary vane vacuum pump and the surrounding environment should always be kept clean to prevent debris from entering the pump.
- During the operation of the pump, the amount of pump oil in the oil tank must not be lower than the center of the oil mark.
- Vacuum pump oils of different types and grades cannot be mixed.
- Two stage rotary vane vacuum pump Due to improper storage or use, when water or other volatile substances enter the pump and affect the ultimate vacuum, open the gas ballast valve to purify it. When the pump oil is polluted by mechanical impurities or chemical impurities, the pump oil should be replaced
- When the two stage rotary vane vacuum pump is not in use, the inlet and outlet ports should be plugged with rubber plug caps to prevent dirt from falling into the pump.
- If the pump is contaminated during work, it must be disassembled and washed. This work needs to be done carefully, and attention should be paid to the disassembly and assembly steps to avoid damage to the parts.
