advance angle; then tighten the 4 tightening bolts of the pump gear according to the torque
requirement.
方法三:转动曲轴至第一缸供油,然后将曲轴转至所需要的供油提前角,再按方法一二拔
动喷油泵体或转动喷油泵凸轮轴至第一缸开始供油位置,扭紧紧固螺栓,检查供油提前角,若
符合要求,再按扭紧力矩要求扭紧紧固螺栓。
Method 3: rotate the crankshaft to first cylinder supplying fuel; rotate the crankshaft to the
fuel supply advance angle as required; then move the fuel injection pump body or camshaft to
first cylinder starting supply position as per Method 1 and Method 2; tighten the tightening
bolts and check the fuel supply advance angle; if it conforms the requirement, tighten the
bolts according to the torque.
供油角度自动提前器为机械离心式,作用转速为
500
~
1400r/min
,供油角度提前量为
5°
~
6°
,
在提前器外圆上刻有表示供油时刻开始的刻度,此刻度与固定在泵体上的刻度对正时,表示此
时喷油泵第一缸供油时刻的开始。用户应定期检查提前器内润滑油的油量,并予以补充加足。
