Outdoor Type Vacuum Pump Unit Transformer Evacuating Vacuum Degree 0.05 Pa
Functions
VR series vacuum pump unit is composed of a Roots pump (mechanical booster pump) as the main pump and a rotary vane vacuum pump as a fore-stage pump. The unit is mainly used for vacuuming and drying various vacuum systems that require high pumping speed and obtain medium and high vacuum, especially suitable for vacuuming transformers. This vacuum drying and exhaust unit is widely used in vacuum smelting, vacuum heat treatment, welding, chemical pharmaceuticals, vacuum coating, electronic components, and other industries.
Application
- It is mainly used to extract the gas in the container so that the container can reach high vacuum requirements, and can also be used for vacuum drying.
- This unit is particularly suitable for vacuuming transformers in the power industry, and can also be used for vacuuming in vacuum smelting, welding, chemical pharmaceuticals, vacuum coating, electronic components, and other industries.
Advantages
- It has the characteristics of a fast start-up, high pumping speed, stable performance, and easy operation.
- Roots pump is used as the main pump and rotary vane vacuum pump is used as the front pump.
- It is fully automatic and can be operated unmanned. The operating status is displayed by the indicator light.
- The machine is humanized in design, with low noise and low energy consumption to save operating costs.
- Equipped with a pipeline filter, it can effectively prevent larger particles of impurities from entering the system and damaging the vacuum pump.
- It is equipped with a gas circuit check device to prevent gas reflux, vacuum leakage, oil leakage, and other phenomena in the case of abnormal sudden shutdown.
- Imported pumps can quickly obtain a higher working vacuum degree.
