五种换向器比较摇臂式喷头换向器的工作原理是:当喷管旋转至扇形喷洒的一端时,在摇臂尾部运动轨迹的中途迅速加入一个突起构件,构件的突出部位阻挡摇臂并承受摇臂的打击力量,使喷管向相反方向旋转。当喷管旋转至扇形的另一端时,突起构件退出,让摇臂恢复正常摆动,喷头重新正转。如此循环不止。每一个换向器都有突起构件这一基本元件。按照突起构件的形状和运动方式,可以将换向器分成以下几类: Five Commutator Comparison Rocker nozzle commutator works: When the nozzle is rotated to fan spray one end, the trajectory in the rear end of the rocker quickly added a protruding member, the member of the prominent part of the blocking arm And to withstand the impact of the rocker arm, the nozzle to the opposite direction of rotation. When the nozzle is rotated to the other end of the sector, the protruding member is withdrawn to allow the swing arm to resume normal swinging, and the sprayer rotates forward again. This cycle more than. Each commutator has the basic element of a protruding member. According to the shape of the protruding member and movement, the commutator can be divided into the following categories:
