style="text-indent:25px">溢流閥主要有兩個作用分別是維持液壓系統(tǒng)壓力穩(wěn)定和限制系統(tǒng)的高壓。它安裝在液壓泵出口的位置，如果出現(xiàn)液壓油路負載過重的情況，那么液壓油就能夠從溢流閥回油箱，實現(xiàn)對系統(tǒng)卸載，來保護液壓系統(tǒng)。在日常工作中，我們總結了以下幾種溢流閥故障：溢流閥阻尼孔堵塞。阻尼孔被堵塞，是比較常見且容易被忽視的問題，它是由于液壓油不純，油中雜質太多引起的。而維修人員往往會認為是溢流閥失效。一旦液壓油中有雜質存在，而溢流閥開度又過大過猛，就會造成溢流閥芯卡死無法回位，使機械無法正常運作。出現(xiàn)這種情況后，不要急著更換溢流閥，而是要檢查溢流閥是否堵塞了，先對溢流閥進行清洗，然后將閥芯回位，按照機械要求的載荷量重新調定其開啟壓力。液壓缸和液壓馬達是液壓系統(tǒng)執(zhí)行元件的兩個主要組成部分。合肥液壓系統(tǒng)哪個牌子好</p><p
