style="text-indent:25px">挖掘機(jī)故障排除：不能回轉(zhuǎn)及回轉(zhuǎn)角度偏大。貴州挖掘機(jī)除回轉(zhuǎn)外其他部件運(yùn)轉(zhuǎn)正常，因?yàn)橹鞅煤妥詨簻p壓閥為挖掘機(jī)液壓部分的共用元件，故說明主泵和自壓減壓閥不存在故障。在回轉(zhuǎn)電磁閥控制油路的出口處，接一個(gè)三通接頭并連接一只量程4MPa的壓力表，操作挖掘機(jī)進(jìn)行回轉(zhuǎn)，結(jié)果發(fā)現(xiàn)此處的壓力*為O.1MPa，說明解除制動(dòng)的油壓太低，無法解除制動(dòng)，從而使挖掘機(jī)不能回轉(zhuǎn)。在拆卸回轉(zhuǎn)鎖定電磁閥時(shí)發(fā)現(xiàn)，閥芯已被卡住，取出閥芯時(shí)看見里面有一小段破損的O形密封圈。清洗各元件，重新安裝后試機(jī)，回轉(zhuǎn)動(dòng)作恢復(fù)正常，故障排除。挖掘機(jī)回轉(zhuǎn)操作結(jié)束，操作手柄已處于中位時(shí)，挖掘機(jī)在慣性力的作用下回轉(zhuǎn)角偏大，無法停在預(yù)定位置。據(jù)分析，這種象是由于回轉(zhuǎn)制動(dòng)不及時(shí)或制動(dòng)力不足造成的，它與解除制動(dòng)的油壓大小及回轉(zhuǎn)鎖定磁閥、回轉(zhuǎn)制動(dòng)片和制動(dòng)密封等零部件有關(guān)。在檢查制動(dòng)回油路時(shí)發(fā)現(xiàn)，在回油路的節(jié)流孔處有一膠質(zhì)顆粒物，節(jié)流孔雖沒有完全被堵死，但已導(dǎo)致回油過慢，使得制動(dòng)部分起作用的時(shí)間推遲，因此使上部回轉(zhuǎn)停止時(shí)滑移量（即回轉(zhuǎn)角度）過大。清洗各元件特別是節(jié)流孔及細(xì)小油道。安裝各元件后試機(jī)時(shí)，回轉(zhuǎn)滑移量已在規(guī)定的范圍內(nèi)，故障排除。</p><div
