阀杆与阀体的密封靠O型密封圈来完成,若密封圈老化或损坏,在体系压力效果下液压油会顺着阀杆流出,导致阀体渗漏油。扫除此毛病只需替换O形密封圈即可。

叉车选用的是分片式多路换向阀,该型号多路阀的结构杂乱,精密度较高,该阀包括外壳、起升阀杆、歪斜阀杆、复位绷簧、安全阀以及锥形阀等部件,在内部形成进油道、作业油道、回油道、溢油道及总回油道,使液压油在不同作业状况下在各油道内活动,到达不同的作业意图。

内漏的原因及扫除办法是:

(1)阀杆与阀体之间磨损空隙过大多路换向阀起升和歪斜的阀杆上各有三个沟槽,沟槽和油道合作能够接通或切断油路,改动作业方式。杰出的分配阀的阀杆与阀体之间的空隙很小,漏油很少,故液压缸下降或歪斜量很小,不影响作业。但磨损空隙过大时,液压油在作业泵发生的压力下,就会形成作业油道中的油与回油道或溢油道相通,自动回到油箱。发生原因主要是,因分配阀长期使用或油液不清洁等加快了阀杆与阀体的磨损,破坏了合作密封面,导致漏油。修正时若阀杆磨损较轻,可对阀杆镀铬磨光;若阀杆磨损严峻,则需求替换。
