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。
