Micro air pump and micro vacuum pump have certain differences in function and use, although they belong to the category of micro pump, but their characteristics and application scenarios are different.
Micro air pump
Definition and function: Micro air pump is a small volume of gas conveying device, its working medium is mainly gaseous. It is mainly used for gas sampling, gas cycling, vacuum adsorption, vacuum pressure holding, pumping, pumping, pressurizing and other gas conveying tasks.
Classification: According to the use can be divided into micro negative pressure pump, micro vacuum pump, micro gas circulation pump, micro gas sampling pump, micro air pump, micro air pump, micro air pump and so on. According to the working principle can be divided into diaphragm type, electromagnetic type, impeller type, piston type and so on.
Advantages: small size, low noise, low power consumption, easy operation and maintenance, and relatively cheap. In addition, the micro air pump usually allows the medium to be rich in water vapor, and is mostly dry, oil-free design, which will not pollute the working medium.
Application scenario: Widely used in medical and health, scientific research, laboratory, environmental protection, instrumentation, chemical industry and other industries.
Micro vacuum pump
Definition and function: Micro vacuum pump is a kind of micro air pump, especially those with a suction nozzle and exhaust nozzle, and can continue to form vacuum or negative pressure at the inlet of the micro pump. Its main function is to pump air or create a vacuum environment.
Features: The miniature vacuum pump usually has a lower limit vacuum degree (that is, a higher vacuum capacity), which can effectively extract the gas in the container, so that the container reaches a certain vacuum state. In addition, the miniature vacuum pump also has a high pumping rate, which can quickly remove gas.
Application scenario: The miniature vacuum pump is especially suitable for the occasions that require vacuum environment, such as vacuum packaging, vacuum adsorption, vacuum drying, vacuum detection and other fields. In scientific research and laboratories, micro vacuum pumps are also commonly used for tasks such as gas sampling and gas analysis.
Differential summary
Functional focus: The function of the micro air pump is more extensive, covering many aspects of gas transmission, including pumping, pumping, pressurization, etc. The miniature vacuum pump is more focused on pumping and creating a vacuum environment.
Application scenarios: Although both have applications in many fields, micro vacuum pumps are more common in specific situations that require a vacuum environment.
Performance parameters: The miniature vacuum pump usually has a lower limit vacuum degree and a higher pumping rate to meet the strict requirements of the vacuum degree; The performance parameters of the micro air pump may vary depending on the specific model and use.
In summary, micro air pump and micro vacuum pump have certain differences in function and use, and users should be comprehensively considered according to specific needs and application scenarios when choosing.
