Dry pumps and oil pumps are two common types of vacuum pumps, which have significant differences in their working principles, scope of application, maintenance costs, and environmental performance.

Working principle: The dry pump achieves pumping by changing the volume of the working chamber through mechanical motion, without the need for lubricants; The oil pump relies on oil to seal and lubricate moving parts, improving pumping efficiency.

Scope of application: Dry pumps are suitable for relatively clean gas environments, such as semiconductor manufacturing and * * equipment; Oil pumps are suitable for processing gases containing water vapor and impurities, and are commonly used in fields such as chemical industry and food processing.

Maintenance cost: The dry pump does not require regular oil replacement, resulting in lower maintenance costs; The oil pump requires regular replacement of lubricating oil, which increases maintenance costs.

Environmental performance: The dry pump will not produce oil pollution during operation, making it more environmentally friendly; The oil pump may produce oily exhaust gas, which has a certain impact on the environment.
