How the vacuum pump works?
The vacuum pump must be familiar to everyone, but you don't necessarily understand how it works. Let's take a look at it as below:
1. When the vacuum pump is running, due to the centrifugal force, the water forms a closed ring of approximately equal thickness depending on the shape of the pump cavity. The inner surface of the upper part is just tangent to the impeller hub, and the lower inner surface is just in contact with the tip of the blade (actually the blade has a certain depth of insertion in the water ring).
2. A crescent-shaped space is formed between the impeller hub and the water ring, and this space is divided by the impeller into a plurality of small cavities having the same number of blades. If the upper part of the impeller is 0°, the volume of the small cavity becomes smaller from 180° before the rotation, and it communicates with the suction port on the end face. At this time, the gas is sucked in, and when the inhalation is finished, the cavity is small. It is isolated from the suction port. When the impeller continues to rotate, the small cavity becomes smaller and smaller, so that the gas is compressed. When the small cavity communicates with the exhaust port, the gas is discharged outside the stainless steel vacuum pump.
Vacuum pump has its unique advantages and advantages. It has been widely used in food vacuum packaging, medicine, printing machinery paper conveying, glass industrial conveying, vacuum fixture, drying and other units.
