力士樂(lè)換向閥0811404766的結(jié)構(gòu)特點(diǎn)分析
故障原因:
控制換向閥中閥芯動(dòng)作速度的兩端節(jié)流閥謂節(jié)
不當(dāng),造成回流油阻尼大,也是使換向閥不能正常
作的因素,適當(dāng)調(diào)節(jié)兩端節(jié)流的液壓油流量即可
拆卻維修。雙向換向閥換向閥是具有兩種以上
流動(dòng)形式和兩個(gè)以上油口的方向控制閥。是實(shí)
解決。被油缸活塞推動(dòng)的零部件,由于其滑動(dòng)的
導(dǎo)潤(rùn)滑不良、裝配不合理等因素,使運(yùn)動(dòng)零件阻
力同樣會(huì)造成換向閥無(wú)法正常工作。必要時(shí)應(yīng)
現(xiàn)液壓油流的溝通、切斷和換向,以及壓力卸載
和順序動(dòng)作控制的閥門。
復(fù)位彈簧疲勞或折斷:
此類故障與彈簧的材質(zhì)選用有一定關(guān)系。電磁
擁有良好的彈力,耐疲勞特性。表面處理工藝
的加強(qiáng)能有效阻止彈簧被腐蝕,具有很高的使
換向閥使用進(jìn)口琴鋼線彈簧,表面染黑處理,
用壽命。遇到此類故障必須兩邊彈簧同時(shí)更換
,并注意長(zhǎng)度與電磁換向閥設(shè)計(jì)值相匹配。
