We always hope to improve the geometric pumping speed of the vacuum pump as much as possible without increasing the total size of the rotary vane vacuum pump. It can be seen from the previous calculation that the following ways are available:
1. Decrease b: select the smaller b to obtain the larger K, so as to increase the pumping speed. But if b is chosen too small, it will inevitably increase vibration and noise. So it's actually hard to do.Rotary-vane-vacuum-pump-speed
2. Increase speed (n) : the speed of rotation is greatly increased, which can greatly increase the geometric pumping speed. On the contrary, if the required pumping speed is fixed, the increase of rotating speed will reduce the geometric size of the pump. A direct pump is one example.Composition-and-type-of-low-vacuum-unit
3. Increase the number of spinning plates: although increasing z does not increase the pumping speed in a proportional way as increasing n, it also has unique advantages, that is, when adopting the direct connection structure, the rotating speed has reached a certain high value, and increasing the spinning plates can improve the pumping speed without reducing b value or increasing the maximum linear speed. It can reduce vibration and increase the ultimate vacuum degree.
