電磁閥或泄荷閥不能正常工作；油箱油位過低或過濾器堵塞；調(diào)高安全閥壓力整定值低或損壞；調(diào)高液壓泵損壞；液壓系統(tǒng)進(jìn)入過多的空氣或注入的油液不合格。排除方法接好相關(guān)線路或更換按鍵盤；更換主控器或輔助板觀察電磁閥上的顯示燈。電源送電時燈亮，不亮?xí)r檢查供電線路，否則，查電磁閥的吸合力和閥芯，更換電磁閥；要求添加合格的液壓油或清洗濾油器；重新進(jìn)行調(diào)整或更換；更換液壓油泵；對液壓系統(tǒng)進(jìn)行排氣或更換油液。四滾筒升起后自動下降故障原因分析液壓鎖鎖不緊或閥芯卡死；管路損壞或接頭松動；調(diào)高油缸前后腔串液。排除方法修復(fù)或更換；擰緊或更換管路；更換調(diào)高油缸。五電源晶體管故障及檢測方法首先斷開負(fù)載電機(jī)接線，用數(shù)字萬用表檢查。晶體管IGBT外形見圖，IGBT原理見圖。用萬用表二極管檔測量集電極c與發(fā)射極E之間的參數(shù)，靜態(tài)檢測時正筆接發(fā)射極E，負(fù)筆極接集電極c時，好的晶體管顯示值應(yīng)在0.0.v直流之間；若正筆接集電極c負(fù)筆接發(fā)射極E時，好的晶體管應(yīng)顯示讀數(shù)為溢出，也就是說c與E截止或一個不斷上升的數(shù)字。動態(tài)檢測時負(fù)極接B，正極接E時，c與E讀數(shù)應(yīng)在0.-0.。
