蒸汽机车经常发生汽室涨圈折损,轻则影响机车配气,降低机车牵引力,浪费燃料,重则可造成阀装置破损,甚而导致机车其他传动系统的破坏等重大事故的发生。 如何减少汽室涨圈的折损?据我多年的检修经验认为,汽室涨圈折损的主要原因是“汽室壁偏段磨超限”所造成。为了降低汽室涨圈的折损率,就必须从减少汽室套偏段磨入手。 Steam locomotive often occur gas cylinder up circle damage, ranging from affecting the locomotive gas, reducing locomotive traction, waste of fuel, can cause valve device damage, and even lead to other locomotives and other major transmission system damage and other major accidents. How to reduce the loss of gas chamber up ring? According to my many years of maintenance experience that the main reason for the collapse of the gas chamber ring is “excessive partial chamber wall grinding chamber caused”. In order to reduce the loss rate of the gas cylinder ring, it is necessary to reduce the gas chamber from the partial wear grinding arm.
