一、随转速的提高,拉杆的移动为什么在作用点时突然由慢变快? 答:调试Ⅱ号喷油泵时,调速器的作用点通常是根据拉杆移动的快慢来确定的.当操纵臂处于最大供油位置,使转速由低于额定转速的某一转速均匀提高时,拉杆随之向减小供油量方向移动,在此过程中,拉杆移动由慢变快的分界点,即是作用点,其所对应的转速,即为调速器起作用转速. 由Ⅱ号泵调速器作用原理可知,当操纵臂处于最大供油位置,在扭矩校正范围内,校正弹簧后座
First, with the speed increase, why the rod movement in the role of the sudden change from slow to fast? Answer: Debugging II pump, the governor of the role of the point is usually based on the speed of the rod to determine .When the manipulator In the maximum oil supply position, the speed is increased by a certain speed lower than the rated speed, then the lever moves to reduce the fuel supply. In this process, the lever moves from the point where the speed slows down, that is, The role of the point, which corresponds to the speed, that is, governor speed. By Ⅱ pump governor principle shows that when the manipulator arm is in the maximum fuel supply position within the torque correction, calibration spring rear seat
