vacuum pumps in white appliance of application
The application of vacuum pumps in white appliances is mainly divided into two categories: home appliance terminals and home appliance equipment.
一、The home appliance terminals are mainly Haier, Midea’s home appliance factories, which generally use rotary vane pumps and Roots pumps.
1.The application of rotary vane pumps in home appliance terminals is mainly reflected in the following aspects:
Refrigerator: Rotary vane pumps are used in the refrigeration system of refrigerators to help extract air in the system and form a vacuum, thereby improving refrigeration efficiency.
Air conditioners: In the production process of air conditioners, rotary vane pumps can be used in processes such as vacuum impregnation to improve the performance and quality of air conditioners.
Light bulb, fluorescent lamp, bottle production: Rotary vane pumps are used in the production process of these products, which may involve processes such as vacuum packaging.
In summary, the application of rotary vane pumps in home terminals is mainly focused on improving the performance and quality of home appliance products, as well as special process requirements in the production process.
2.The application of rotary vane pumps in refrigeration is mainly reflected in refrigeration maintenance work.
The rotary vane pump can pump the gas in the refrigeration system from 105Pa to below 1Pa. It can be used to create vacuum, and can also be used as a pre-pump for high vacuum pumps or ultra-high vacuum pumps. It is one of the most basic vacuum acquisition equipment. The rotary vane pump was invented in 1909 by Wolfgang Gade, a German physicist and founder of modern vacuum technology. It has been widely used in metallurgy, machinery, military industry, electronics, chemical industry, petroleum and medicine. It is suitable for vacuum packaging of food, vacuum blistering in the plastics industry and other fields.

二、The application of vacuum pumps in household appliances is mainly in refrigerant charging machine.
1.A refrigerant charging machine is a device used to repair automotive air conditioning systems. It can perform a series of operations such as refrigerant recovery, purification, and refilling. During use, the automotive air conditioning system must first be evacuated using a vacuum pump to remove air and moisture from the system to ensure that the system can operate at high efficiency. The evacuation process is achieved by creating an environment below atmospheric pressure so that the air and moisture in the system are drawn out.
2.The rotary vane pump is mainly used for vacuuming in the refrigerant charging machine.
Vacuuming is to remove the air moisture (free water, surface water, molecular bound water) inside the refrigeration system; and remove the dirt inside the refrigeration system (copper powder, processing oil, extraction oil, etc.) to ensure the injection of refrigerant. It plays a very important role in the refrigerator manufacturing process.
