              液壓速度控制系統(tǒng)常見故障

              液壓系統(tǒng)的速度調(diào)節(jié)是液壓泵站的重要部分,執(zhí)行機構(gòu)速度不正常,液壓機械就無法工作。那么速度控制系統(tǒng)主要故障及其産生原因有哪些呢?

              一、載荷增加時進給速度顯著下降的主要原因

              1.調(diào)速閥中的減壓閥卡死于打開位置,則載荷增加時通過節(jié)流閥的流量下降;

              2.液壓缸活塞或系統(tǒng)中某個或幾個元件的洩漏隨載荷、壓力增高而顯著加大。

              二、執(zhí)行機構(gòu)爬行的主要原因

              1.系統(tǒng)中進入空氣;

              2.在進油節(jié)流調(diào)速系統(tǒng)中,液壓缸無背壓或背壓不足,外載荷變化時,導(dǎo)緻油缸速度變化;

              3.節(jié)流閥的閥口堵塞,系統(tǒng)洩漏不穩(wěn)定,調(diào)速閥中減壓閥不靈活,造成流量不穩(wěn)定而引起爬行;

              4.液壓油泵的流量脈動大,溢流閥振動造成系統(tǒng)壓力脈動大,是液壓缸輸入壓力油波動而引起爬行;

              5.由于導(dǎo)緻潤滑不良,導(dǎo)軌與液壓缸軸線不平行,活塞桿密封壓的過緊,活塞桿彎曲變形等原因,導(dǎo)緻液壓缸工作行程時摩擦力變化較大而引起爬行。

              三、執(zhí)行機構(gòu)(液壓缸、液壓馬達)無小進給的主要原因

              1.節(jié)流閥的節(jié)流口堵塞,導(dǎo)緻無小流量或小流量不穩(wěn)定;

              2.調(diào)速閥定差式減壓閥的彈簧過軟,使節(jié)流閥前后壓差過低,導(dǎo)緻通過調(diào)速閥的小流量不穩(wěn)定;

              3.調(diào)速閥中減壓閥卡死,造成節(jié)流閥前后壓差隨外載荷而變,經(jīng)常見到的是由于小進給時荷載較小,導(dǎo)緻最小進給量增大。
