阀的修复方法及原理
(1)零件组合选配维修法。液压阀制造过程中,为提高装配精度多采用选配方法,即对一批加工完毕的零件,如阀体和阀芯。依据实际尺寸选择配合间隙最为恰当的一对进行装配,以保证良好的阀芯滑动和密封性能。也就是说,同一类型的液压阀,阀芯与阀体的配合尺寸有一定的差异。
对于使用企业,当某一种失效液压阀的数量较多时,可以将所有阀拆卸清洗,检查测量各零件,依据检测结果将零件归类,依据下列方法重新组合选配。
如果阀芯、阀体属于均匀磨损,工作表面没有严重划伤或局部严重磨损,则依照有关手册,选择出具有合适间隙的阀芯、阀体重新装配。如果阀芯、阀体磨损不均匀或工作表面有划伤,通过上述方法已经不能恢复液压阀功能,则选择满足加工余量要求的过盈量的一对阀芯、阀体(孔尺寸小的阀体与外径尺寸大的阀芯),对阀体孔进行铰削或磨削,对阀芯进行磨削,达到合理的形状精度配合精度后装配。
(2)恢复尺寸维修法。采用零件选配法维修液压阀虽然工艺较为简单,但有其局限性,而采用修理尺寸法则适应更为广泛的场合。简易可行的修理尺寸法主要有更换零件法和修补法两类。
更换零件法是将已经失去配合精度的阀芯拆卸,测量并画出零件图,检查阀体导向孔或阀座的磨损及损坏程度,并依此确定修复加工量,然后进行精加工(精铰或磨削)修复。对于有一定锥度的阀座,要制作特定的加工工具。加工到相应精度后,测量实际尺寸,然后依据此尺寸加工新的阀芯。这种维修方法维修精度高,适应面广,可完全恢复原有的精度,适合于有一定加工能力的企业。
