  各缸供油均匀性及标定油量的检查与调试可在一般喷油泵试验台上进行,但必须辅以专用胎具,这是因为K型喷油泵本身没有凸轮轴的缘故。

柴油机泵的调整要求如下:

  (1)EDINGGONGKUANGXIA(1 300 r/min):GONGYOULIANG12. 5mL/400CI,BUJUNYUNDU≤60/0。

  (2)DAISUGONGKUANGXIA(250 r/min):GONGYOULIANG4.O~4.SmL/400CI,BUJUNYUNDU≤20u/0。

  调整各缸供油均匀性时,要先拆开调整缸的高压油管,松开出油阀紧座,以便调整时转动柱塞计量泵皇冠即时比分套,然后松开扇形板紧固螺钉。当要增加该缸油量时,顺时针转动扇形板,减少油量时则逆时针转动。调整后依次拧紧各件,再进行油量检查。

  K系列气动油桶泵采用在不锈钢液下泵皇冠即时比分与齿轮室接合面之间加调整垫的方法调整供油提前角,垫片厚度一般有0.lmm、0.2 mm及0.3mm三种。垫片厚度增加,供油提前角减小,反之增大。柴油机供泵油提前角为150~190曲轴转角。一般每调整0.lmm垫片厚度,供油提前角约变化10左右。

  当采取以上方法不能将供油提前角调整正确或调整后各缸供油提前角差别较大时,可将油泵卸下,拆下油泵皇冠即时比分滚轮部件,增减滚轮体与柱塞头部之间的调整垫片来弥补。此处垫片厚度增加,供油提前角增大,反之减小。注意:一般不要采取这种方法调供油时间,因为如此调整将影响供油预行程。

  柴油机泵的校正行程为1.0一1. 5mmo在调整时应注意,校正弹簧与校正行程二者'一定要止动一个,调整另一个;调定位置后,应改变一下发动机的负载,使其由小到大,看转矩曲线是否符合要求,直到符合要求后再将内锁紧螺母及盖形螺母拧紧。
