stainless steel vacuum pump working principle

With the needs of social work, stainless steel vacuum pump is constantly popular production, more and more people contact the use of it, the understanding of it also began to deepen, at the same time, there are many want to understand the problem. The following is the working principle of stainless steel vacuum pump.

During the operation of stainless steel vacuum pump, due to the centrifugal force, water forms a closed ring which is approximately equal in thickness and is determined by the shape of pump chamber. The upper inner surface is just tangent to the impeller hub, and the lower inner surface is just in contact with the tip of the blade. At this time, a crescent shaped space is formed between the impeller hub and the water ring, and this space is divided into several small cavities with the same number of blades by the impeller. If the upper 0 ° of the impeller is taken as the starting point, then the volume of the small cavity increases from small to large when the impeller is 180 ° before rotation, and it is connected with the suction port on the end face. At this time, the gas is inhaled, and when the suction is finished, the small cavity is connected with the suction When the impeller continues to rotate, the small cavity becomes smaller, so that the gas is compressed; when the small cavity is connected with the exhaust port, the gas is discharged from the stainless steel vacuum pump.
