Working Principle
The Screw Vacuum Pump by Sanzhi (Henan) Compressor Co., Ltd. represents an exceptional feat of engineering brilliance. Designed with dual precision screws that rotate synchronously in reverse at high velocities within the pump casing, this dynamic mechanism generates a formidable suction and exhaust effect. Each screw is subjected to meticulous dynamic balance correction and is robustly supported by premium-quality bearings, ensuring flawless operation within the pump casing. Remarkably, the screws are engineered with exact clearances to eliminate friction, resulting in supremely smooth operation and ultra-quiet performance. This cutting-edge design enables the pump to handle substantial quantities of water vapor and minor amounts of dust-laden gases with remarkable efficiency. Featuring superior ultimate vacuum levels, reduced power consumption, and maintenance-free operation, our screw vacuum pumps set new standards in energy efficiency and reliability. These distinctive attributes render them indispensable in diverse industries such as pharmaceuticals, chemicals, semiconductors, and food packaging, where a pristine and high-performance vacuum is essential.
