1）液壓泵的軸向、徑向間隙由于磨損而增大； 2）泵的“困油”未得到圓滿解決； 3）泵內(nèi)零件加工及裝配精度較差； 4）泵內(nèi)個(gè)別零件損壞等。 2. 液壓控制閥引起的壓力失調(diào) 1）在壓力控制閥中： ①先導(dǎo)閥的錐閥與閥座配合不良； ②調(diào)壓彈簧太軟或損壞； ③主閥芯的阻尼孔被堵塞，滑閥失去控制作用； ④主閥芯被污物卡住在開(kāi)口位置或閉口位置； ⑤溢流閥作遠(yuǎn)程控制用時(shí)，其遠(yuǎn)程連接通道過(guò)小或泄漏； ⑥溢流閥作卸荷閥用時(shí)，其控制卸荷的換向閥失靈等。升降臺(tái)液壓系統(tǒng)價(jià)格</p><p
