有许多农机修理专业户和机手,在检修柴油机时,由于缺少内径千分尺、量缸表等量具,往往用目测、手摸缸套口台肩来判定是否需更换缸套,这种直观感觉很不准确。下面介绍一种用活塞环测量缸套磨损量的方法。先将活塞连杆组拆下来,清除缸口积炭后,用一道标准气环放在缸口位置,用长塞尺测量环口间隙△;然后用活塞顶平推气环,使其处于缸套内的不同位置进行测量。 (1)活塞上止点第一道气环位置时,测量环口间隙△1;
There are many agricultural machinery repair specialist and hand, in the repair of diesel engine, due to the lack of diameter micrometer, measuring cylinder and other measuring tools, often with visual inspection, hand cylinder liner mouth to determine whether the need to replace the cylinder liner, this intuition does not feel very accurate. Here’s a way to measure the amount of wear on a cylinder liner with a piston ring. First remove the piston rod group, clear the cylinder after coke, with a standard gas ring on the cylinder port position, with a long feeler gauge ring gap △; then push the ring with the piston flat top to make it in the cylinder Set of different locations for measurement. (1) piston ring when the first ring on the top dead center position, measuring the ring gap △ 1;
