Vacuum pump is a device that can extract the gas in the container to form a vacuum environment. Its working principle is mainly based on the motion law of gas molecules. Vacuum pump is usually composed of driving device, suction device and control system.
vacuum pump generates power through the driving device to drive the air extraction device to work. One or more impellers are arranged inside the air extraction device, and the edge of the gas is pushed outward by rotating motion to form a low pressure area, so that the gas molecules enter the air extraction device. As the impeller rotates, the gas molecules are continuously pushed and pulled out of the container, thereby forming a vacuum environment.
The main functions of the vacuum pump are as follows:
1. Create a vacuum environment: The vacuum pump can extract the gas in the container to reduce its pressure to the required vacuum degree, thereby creating a vacuum environment suitable for the needs.
2. Pretreatment: In some industrial production processes, it is necessary to remove impurities in the air to reduce the impact on product quality. The vacuum pump can purify the gas and improve product quality by extracting impurities in the air.
3. Vacuum evaporation: In some material processing processes, the material needs to be heated to a high temperature and evaporated in a low pressure environment. The vacuum pump can pump out the gas in the container to form a low-pressure environment and evaporate the material at high temperature.
4. Experimental research: In scientific research and laboratories, different experiments require different atmospheric pressure environments. The vacuum pump can create a suitable air pressure environment according to the experimental requirements and help researchers to carry out experimental research.
