What Is a Rotary Vane Pump?
The rotary vane pump is a two-stage structure, which is composed of two parts, a high-pressure stage and a low-pressure stage. Its suction port is connected to a vacuum container or vacuum equipment. During operation, a large amount of gas in the container is sucked in and discharged. When the equipment obtains a vacuum, the high-pressure stage exhaust valve disc will be closed, and the gas sucked in the high-pressure stage will be transferred to the second stage, and sucked in and discharged through the second stage, so that the vacuum equipment can obtain a certain vacuum. According to the user's usage, a vacuum booster pump can be equipped as the foreline pump. Due to the enhanced pumping force of the booster pump, the foreline pump can be continuously removed, which can make the equipment obtain a higher vacuum.

- 1. Strong ability to exclude water vapor.
- Can be widely used in refrigerators, air conditioners, light bulbs, fluorescent lamps, bottle production and electronics, metallurgy, medicine, chemicals, oil filters, printing machinery, packaging machines and other industries in vacuum smelting, vacuum welding, vacuum impregnation, vacuum coating, vacuum Heat treatment, vacuum drying, vacuum packaging and other processes. It can be used as ancillary and experimental research applications for diffusion pumps, roots pumps, molecular pumps, etc.
- 1. Always pay attention to the oil level.
- 2. Open the valve slowly after the pump starts.
- 3. Always pay attention to whether the pump is running normally, whether there is any special sound, and whether the motor is overloaded.
- 4. Pay attention to whether the cooling water is interrupted.
- 5. Pay attention that the pump temperature does not exceed 40 ° C.
- 6. If the pump temperature drops below 5 ° C after shutdown, the cooling water in the pump must be removed.
- 7. If it is necessary to make the pump remove toxic and corrosive ferrous metal gas, chemically change the gas to the rotary vane pump, and exceed normal temperature and dusty gas, install neutralization on the intake pipe, cool, Filters and other related devices are used in combination, otherwise the performance and life of the rotary vane pump will be affected. When removing harmful gases to the human body, corresponding pipes should be installed and the exhaust gas should be led to the outdoor and away from the work area for processing.
