Internal Structure
Working Principle
The screw vacuum pump by Sanzhi (Henan) Compressor Co., Ltd. utilizes a pair of meticulously balanced screws that rotate synchronously at high speed in opposite directions within the pump casing. This innovative mechanism creates a powerful suction and exhaust effect. Each screw is precisely aligned and supported by robust bearings, ensuring smooth operation with no friction due to the exact clearances maintained between them. This results in remarkably quiet performance, making it ideal for environments that demand minimal noise. The pump excels in efficiently handling a significant quantity of water vapor and gases with minimal dust content. It offers an unparalleled combination of higher vacuum performance, reduced power consumption, and energy efficiency. Moreover, it is designed to be maintenance-free, providing a hassle-free experience. These attributes make the Sanzhi screw vacuum pump a versatile choice, widely embraced by pharmaceutical, chemical, semiconductor, and food packaging industries that require pristine vacuum conditions.
