When the opener is in use, what is the specific role of the opener's impeller? Gaomi Chengmai Environmental Protection Technology Co., Ltd. took everyone to learn about the role of the opener's impeller!
When the air enters the impeller, on the one hand, it needs to make a circular motion with the circumferential speed U1 of the impeller; on the other hand, it needs to make a relative movement of w1 along the direction of the blades in the channel formed by the two blades. Court VI is the vector sum of UI and W1. When the military air leaves the impeller, the air velocity V2I is the circumferential velocity u, the vector sum of the relative velocity W1, and the air trajectory is shown by the dotted line.
The energy (including "energy and kinetic energy) obtained by a unit weight of air through the impeller of a centrifugal fan, if expressed by the sum of static pressure and dynamic pressure, is generally called the total pressure of the fan. The static pressure and dynamic pressure that the air increases through the impeller That is, the difference between the "pressure and dynamic pressure of the air at the outlet of the impeller and the static and dynamic pressure of the air at the inlet of the impeller."
