2.阀芯不能移动
阀芯不能移动是手动换向阀存在的主要故障,其原因有:
(1)阀芯与阀体内孔配合间隙不当。当阀芯直径小于20mm时, 正常配合间隙在0.008mm到0.015mm范围内;阀芯直径大于20mm 时,正常配合间隙在0.015mm到0.025mm范围内。间隙过大,阀芯在阀体内歪斜,使阀芯卡住,这时需要重配阀芯,也可以采用电镀工艺。间隙过小,摩擦阻力增加,阀芯移不动,这时需要研磨阀芯。
(2)阀芯变形。阀芯变形主要有三个原因:
①油温太高,使阀芯热变形卡住,这时,查找油温升高的原因并降低油温;
②阀芯受到外力发生弯曲变形卡住,这时需要校正或者更换阀芯;
③阀芯表面划伤,阀体内孔划伤,这时,打开换向阀,仔细清洗,研磨修复阀体。
