Working Principle
The screw vacuum pump from Sanzhi (Henan) Compressor Co., Ltd. operates using a pair of precision-engineered screws performing synchronous high-speed reverse rotations inside the pump casing. This action creates a powerful suction and exhaust process. The screws are dynamically balanced and supported by robust bearings, ensuring smooth, frictionless operation within the casing. With a specific clearance between the screws, the pump delivers remarkably quiet performance. It is adept at handling significant volumes of water vapor and minor dust particles, achieving exceptionally high vacuum levels with minimal power consumption. This makes the Sanzhi Oil-Free Screw Vacuum Pump with Advanced Frequency Conversion Features an energy-efficient, maintenance-free solution. Ideal for sectors like pharmaceuticals, chemicals, semiconductors, and food packaging, where stringent clean vacuum conditions are paramount.
