请问往复压缩机大小头瓦间隙测量和调整如何操作呢?有没有间隙标准的说明和调整间隙的检修方法?

连杆装好用内径千分尺量,曲柄销和十字头销用外径千分尺量,间隙小了就刮瓦,间隙大了只能换瓦或者瓦背垫钢皮

多大的机子?以4M65为例,主轴轴径340mm,大头瓦间隙的为0.25mm;小头瓦0.19-0.24mm。间隙标准我记得有个公式好像是轴径尺寸的千分之0.75-1.2左右

这个最好按照厂家的说明书来,说明书是多少,就整成多少,除非说明书有明显的错误!这是就要咨询厂家。

1.用塞尺测量间隙。间隙小调整的话一般是刮瓦。大了的话,基本就报废了。 2.压缩机使用说明书就是标准!!

在轴瓦与轴之间放一根铅丝,轴瓦装好螺丝上紧后再打开,测量铅丝厚度,铅丝厚度就是轴瓦间隙。这是土办法了。

最方便的是外径千分尺配合内径百分表。

请问具体更详细的办法怎么做的呢?

曲轴用外径千分尺量出曲轴是多少锁死,然后把内径百分表卡外径千分尺里把百分表调零,然后直接拿百分表放大头瓦里左右摆动,摆动幅度不超过15度,读最大那个数就是它们的间隙

用塞尺测量曲轴定位轴承(靠近电机侧)轴向间隙,设计值为0.22~0.45mm。用内径百分表检查测量大头瓦间隙和小头瓦间隙,间隙控制0.15MM(标准0.12~~0.18mm).检查十字头衬套与十字头配合是否松动活和缺陷。外观检查,连杆、连杆螺栓无裂纹等缺陷,必要时可用着色、磁粉或超声波进行检查。连杆螺栓端面与连杆螺栓孔端面应对研,接触均匀,接触面积不小于80%。连杆螺栓安装时伸长0.88±0.05mm。
