我们在修理Ⅱ号喷油泵过程中,遇到有些喷油泵的调速器,操纵手柄在静止状态下扳动时,有卡滞现象。经拆卸后检查,发现与操纵手柄连为一体的调速叉两压脚的圆弧面高低不一,当往增加油量方向扳动操纵手柄时,调速叉上圆弧面高的一只压脚与弹簧座表面接触,顶动弹簧座处于倾斜状态;圆弧面低的一只压脚与后弹簧座麦面只是轻微接触,甚至不接触。这就使后弹簧座在倾斜状态下于调节轴上移动,出现弹簧座的内孔一侧与调节轴的一侧紧紧贴合,造成弹簧座移动时阻力加大,扳动手柄时就有卡滞现象。这一点往往容易被疏忽,因此在
We are in the process of repairing pump No. Ⅱ, met some of the fuel pump governor, the joystick in the static state when the flip, there are stuck phenomenon. After disassembly and inspection, found that the control handle connected as one of the speed fork two presser foot arc surface varies, when the direction to increase the amount of oil to pull the control handle, the speed fork on the arc surface of a high The presser foot is in contact with the surface of the spring seat, and the spring seat is tilted; the lower presser foot of the arc surface is only slightly contacted with the spring seat maize surface without touching. This makes the spring seat in the tilted state on the adjustment axis of movement, there is one side of the hole with the spring seat tightly adjust the shaft fit, causing the spring seat to move resistance increases, when you pull the handle there Stuck phenomenon. This is often easily overlooked, so in
