挖掘機(jī)液壓系統(tǒng)故障的三種診斷方法。1、直觀檢查法。對(duì)于一些較為簡單的故障，可以通過眼看、手模、耳聽和嗅聞等手段對(duì)零部件進(jìn)行檢查例如，通過視覺檢查能發(fā)現(xiàn)諸如破裂、漏油、松脫和變形等故障想象，從而可及時(shí)地維修或更換配件;用手握住油管(特別是膠管)，當(dāng)有壓力油流過時(shí)會(huì)有震動(dòng)地感覺，而無油液流過或壓力過低時(shí)則沒有這種現(xiàn)象。2、對(duì)換診斷法。在維修現(xiàn)場缺乏診斷儀器或被查元件比較精密不宜拆開時(shí)，應(yīng)采用此法先將懷疑出現(xiàn)故障的元件拆下，換上新件或其他機(jī)器上工作正常、同型號(hào)的元件進(jìn)行試驗(yàn)，看故障能否排除即可作出診斷。3、儀表測量檢查法。借助對(duì)液壓系統(tǒng)各部分液壓油的壓力、流量和油溫的測量來判斷該系統(tǒng)的故障點(diǎn)在一般的現(xiàn)場檢測中，由于液壓系統(tǒng)的故障往往表現(xiàn)為壓力不足，容易查覺;而流量的檢測則比較困難，流量的大小只可通過執(zhí)行元件動(dòng)作的快慢作出粗略的判斷。因此，在現(xiàn)場檢測中，更多地采用檢測系統(tǒng)壓力的方法。貴州裕鑫工程機(jī)械有限公司是具有完善的施工隊(duì)及專業(yè)的維修隊(duì)伍。主營：挖掘機(jī)的整機(jī)租賃、土石方工程，等業(yè)務(wù)。常年對(duì)外出租，價(jià)格公道，誠實(shí)守信，合作共贏；租用方式靈活、包月、計(jì)時(shí)、按臺(tái)班均可。承接：大小土石方工程，歡迎咨詢洽談

裕鑫工程機(jī)械維修之定期檢查、調(diào)整不解體檢查，即借助于儀器或憑經(jīng)驗(yàn)進(jìn)行聲音聽診。軸承損傷后，發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)時(shí)軸承會(huì)發(fā)出敲擊聲。主軸承發(fā)出的是一種粗重發(fā)悶的“鏜鏜”，發(fā)動(dòng)機(jī)轉(zhuǎn)速越高、負(fù)荷越大聲音也就越響；在突然加大油門時(shí)響聲更為突出，甚至發(fā)動(dòng)機(jī)會(huì)產(chǎn)生振抖；當(dāng)合金層脫落、燒瓦或間隙增大到一定程度時(shí)，在任何轉(zhuǎn)速或負(fù)荷下，一般都能聽見敲擊聲；要確定是哪一道主軸承響，一般可以根據(jù)發(fā)出響聲的位置作出判斷，也可將可疑軸承前后相鄰的兩缸斷火，若聲音降低則說明是該道軸承的響聲。連桿軸承的響聲比主軸承的敲擊聲輕，在機(jī)體外側(cè)聽像是用小錘輕敲耐火磚發(fā)出的“嗒嗒嗒”聲聲音短促而堅(jiān)實(shí)。軸承的解體檢查，通常是在技術(shù)維修時(shí)和修理時(shí)進(jìn)行，有時(shí)實(shí)在不解體診斷發(fā)現(xiàn)問題后進(jìn)行。在機(jī)上檢查（調(diào)整連桿軸承間隙）時(shí)，應(yīng)先放機(jī)油，后拆油底殼和連桿端蓋，在取出軸承。若減磨合金層沒有燒毀、脫落和裂紋，可用刮刀刮去合金層表面雜質(zhì)，修整油槽和油孔，使其露出合金層，待裝復(fù)后調(diào)整間隙即可。
