4WEH22E7X/6EW230N9ETK4力士樂溢流閥*是主閥體(2)阻尼器堵塞,油壓傳遞不到主閥上腔和導(dǎo)閥前腔,導(dǎo)閥就失去對主閥壓力的調(diào)節(jié)作用。因主閥上腔無油壓力,彈簧力又很小,所以主閥變成了一個彈簧力很小的直動型溢流閥,在進(jìn)油腔壓力很低的情況下,主閥就打開溢流,系統(tǒng)就建立不起壓力。
壓力達(dá)不到額定值的原因,是調(diào)壓彈簧變形或選用錯誤,調(diào)壓彈簧壓縮行程不夠,閥的內(nèi)泄漏過大,或?qū)чy部分錐閥過度磨損等。
第二是阻尼器(3)堵塞,油壓傳遞不到錐閥上,導(dǎo)閥就失去了支主閥壓力的調(diào)節(jié)作用。阻尼器(小孔)堵塞后,在任何壓力下錐閥都不會打開溢流油液,閥內(nèi)始終無油液流動,主閥上下腔壓力一直相等,由于主閥芯上端環(huán)形承壓面積大于下端環(huán)形承壓面積,所以主閥也始終關(guān)閉,不會溢流,主閥壓力隨負(fù)載增加而上升。當(dāng)執(zhí)行機(jī)構(gòu)停止工作時,系統(tǒng)壓力就會無限升高。除這些原因以外,尚需檢查外控口是否堵住,錐閥安裝是否良好等
