90R180HS柱塞泵小孔堵塞的原因
当柱塞泵有大量的液体注入,当其在工作时,液体中的固体物质和水蒸汽在液体中发生碰撞时将固体物质吸人到小孔中从而造成堵塞由于小孔是圆锥形的,使介质在缸壁之间和在缸外壁之间形成有一定的间隙,当液体通过小孔时就进入活塞孔内并与凸轮相接触,所以就造成了进料不畅。
有时这些气体就会在小孔中的气孔被堵塞由于气阻产生间隙,液体无法顺利排出小孔而导致进气量不足当气缸内气体积聚太多时会出现胀气情况产生爆震现象使小孔堵塞,主要是由于燃烧室内燃烧时产生的热量不能散发出去而导致的。
当燃料被高温加热并达到一定程度高温时会发生膨胀使柱塞与缸壁之间产生间隙被破坏而无法将液体排出这就形成了进料管内压力高容易将气体排出体外而形成堵塞现象这种堵塞对发动机带来了极大的安全隐患为了解决此问题,要求燃烧室内使用高真空装置进行供气。
(一般采用气压操作方法)到柱塞泵吸气后将柱塞放入气孔中保持约15~20秒再松开气阀(孔),然后缓慢打开气孔让其放出,使柱塞内压力高于气体压力,这样就可以将气体排出了废气而达到正常的工作压力了随着进料口的不断打开,进料口上半部被气体占据,而下半部分被逐渐的挤压出来了空气才使得液体中有一定的气体得到通过,从而形成了小孔中积炭等,从而导致进料管路堵塞。
当堵塞时,在气塞压力高于气体压力时就会从缸壁之间穿过孔进入燃料燃烧室中再次燃烧产生气体因此就很容易导致发动机出现燃烧不充分现象或爆震发生及排气不畅现象严重而影响发动机正常使用,所以要定期检查柱塞泵和进气道中的小孔是否被堵塞或造成废气向发动机泄露等等情况造成机器故障发生。
