DESCRIPTION
The two stage rotary vane vacuum pump has two working chambers. It forms a periodically changing volume in the pump chamber through the high-speed rotating vanes, thereby realizing the suction, compression and discharge of gas. In a two-stage rotary vane vacuum pump, the gas is first sucked into the front pump chamber, and after initial compression, it is sent to the back pump chamber for deep compression to finally reach the required vacuum degree. The twostage rotary vane vacuum pump is suitable for various gas media and has good versatility and adaptability.
Application area
Analysis (spectrometer, mass spectrometry, electron microscopy, etc.)
Coating technology (in the fields of surface protection, decorative layers, displays, screens, etc.)
Medical/pharmaceutical technology (plasma sterilization, freeze-drying)
Vacuum metallurgy (vacuum brazing, vacuum sintering, vacuum alloying, furnace manufacturing)
Leak detection technology (vacuum equipment, car fuel tank, airbag box, packaging)
Research equipment (elementary particle physics, fusion research, laser applications)
Lighting industry (lamp manufacturing)
Pre stage pump used (as Roots pump, molecular pump, vacuum system maintenance)
FEATURES
- Automatic anti-oil return valve. Double anti-oil-return structure and automatic anti-oil-return valve protect your vacuum system more reliably from oil contamination after shutdown.
- ntegral cylinder structure with higher precision and proven rotary vane technology for more stable performance.
- Adjustable gas ballast, multi-speed gas ballast design to meet customer’s vacuum requirement and water vapor handling capacity
- Gear pump forced lubrication, built-in gear pump and constant pressure oil supply mechanism forced oil supply, high suction pressure can also be stable and reliable operation.
- High vacuum degree: It can achieve a higher vacuum degree and is suitable for occasions with high vacuum requirements.
- Fast pumping speed: It has a faster pumping speed and can quickly extract the gas in the container.
- Stable operation: It adopts a bipolar rotary vane structure, which runs smoothly, has low noise and low vibration.
- Easy to maintain: It has a simple structure, is easy to maintain and maintain, and has a long service life.
- Wide range of applications: It can be used for various vacuum equipment, such as vacuum coating, vacuum drying, vacuum distillation, etc.
