Working Principle
The Screw Vacuum Pump by Sanzhi (Henan) Compressor Co., Ltd. is a marvel of engineering, designed with a pair of precision screws that rotate synchronously in reverse at high speeds within the pump casing. This dynamic action creates a powerful suction and exhaust effect. Each screw undergoes meticulous dynamic balance correction and is robustly supported by high-quality bearings, ensuring they operate seamlessly within the pump casing. Notably, the screws are designed with precise clearances to eliminate friction, resulting in exceptionally smooth operation and minimal noise. This advanced design allows the pump to efficiently handle significant amounts of water vapor and small quantities of dust-laden gases. Boasting remarkable features like higher ultimate vacuum levels, reduced power consumption, and maintenance-free operation, our screw vacuum pumps excel in energy efficiency and reliability. These attributes make them indispensable across various industries, including pharmaceuticals, chemicals, semiconductors, and food packaging, where a clean and high-performance vacuum is paramount.
