The trigger wheel rotates with engine RPMs and causes the speed sensor, or pickup oil, to produce triggering voltage pulses that correspond to engine speed and piston position. 觸發(fā)葉輪隨發(fā)動(dòng)機轉速而旋轉，使得轉速傳感器或拾波線(xiàn)圈產(chǎn)生與發(fā)動(dòng)機轉速和活塞位置相對應的觸發(fā)電壓脈沖。
Through changing rotating speed, the germination rate of forage grass seeds that were treated in the hard seed treatment hit-machine could be increased significantly. 通過(guò)改變碰撞機葉輪轉速，可以獲得具有合適擦傷度的牧草種子，滿(mǎn)足提高種子滲透性和發(fā)芽率的要求。
