The micro oil-lubricated
Screw Vacuum Pump, a groundbreaking innovation in modern vacuum technology, has redefined the performance boundaries of industrial-grade vacuum equipment. Its core lies in a high-precision asymmetric screw rotor configuration, which achieves periodic changes in the inter-tooth volume through synchronous counter-rotation. This design not only embodies exceptional mechanical engineering aesthetics in principle but also achieves synergistic improvements in both pumping efficiency and system cleanliness in practice.
The key breakthrough of this device lies in its use of micro-lubricant technology (oil content <2 ppm), which creates an extremely thin yet complete sealing oil film between the rotors. This design cleverly balances the pollution-free nature of a dry
Vacuum Pump with the efficient sealing performance of an oil-lubricated pump. This significantly improves volumetric efficiency (reaching over 95%) and reduces energy consumption with virtually no oil contamination, resulting in energy savings of over 30% compared to traditional vacuum solutions. Furthermore, its operating noise level is kept within the 55–85 dB range, significantly improving the working environment on industrial sites.
Beyond its high efficiency and quietness, this pump's true strength lies in its excellent adaptability to various operating conditions. It can stably handle complex media containing water vapor, particulate dust, and even corrosive gases, without causing clogging or corrosion, significantly improving system reliability. Its compact design offers long maintenance cycles, convenient operation, and continuous operation, making it suitable for high-load industrial environments.
At the application level, this technology is becoming a core vacuum option for high-purity processes. In the pharmaceutical industry, it is used in freeze dryers and solvent recovery systems to ensure GMP-compliant pharmaceutical production environments. In semiconductor manufacturing, it provides a stable and reliable vacuum environment for critical processes such as wafer etching, CVD, and PVD coating. In chemical applications, it can safely handle corrosive and condensable media. It also plays a key role in vacuum preservation in food packaging, OLED display manufacturing in the electronics industry, and oil and gas recovery in oil production.
The micro oil-free screw vacuum pump is not only a technological evolution but also a new type of infrastructure designed to meet the needs of high-end manufacturing, green energy conservation, and intelligent manufacturing. It meets the complex requirements of modern industry for vacuum equipment that is clean, efficient, reliable, and environmentally friendly, demonstrating broad industry penetration and profound technological prospects.
