原理
Theory
LRB三叶罗茨风机是一种容积式风机，其压力
可根据用户的要求在允许的范围内加以调节。
在机壳内部设置有两组互朝相反方向回转的叶
轮，可在叶轮与叶轮、叶轮与壳体间仅留极小
缝隙的状态下回转。当叶轮经过吸入端与壳体
之间时，叶轮捕捉一定量的空气，随叶轮转旋
，空气侧移，压力逐渐升高再送至出口端。
LRB is a displacement blower, the pressure can
be adjusted according to the requirement of the
user in allowing range. There are two impellers in
the blower body which rotate in the opposite di-
rection, in order to let the impeller rotate, there
are some tiny gaps between the impeller to body,
impeller to impeller. When the impeller rotates
through the suction inlet, it can gather an amo-
unt of air between the body and impeller, then
the impeller go on rotating, and the air will be
pressured, the pressure in the body will rise, finally
the air has been sent to the outlet.
