挖掘機(jī)工作時(shí)，會(huì)發(fā)現(xiàn)大臂舉升緩慢。是什么原因呢？挖掘機(jī)大臂舉升，是靠油泵輸出的壓力油順管道經(jīng)閥進(jìn)入大臂油缸的后腔，油缸內(nèi)的活塞在工作油液壓力的作用下移動(dòng)，通過(guò)活塞桿將大臂舉起。由此看來(lái)，大臂舉升的速度與進(jìn)入油缸油液的壓力和流量有關(guān)。根據(jù)輸入油缸的功率等于油缸輸出的功率這一道理，再根據(jù)輸入液壓油缸的功率P等于液壓油缸的工作壓力與進(jìn)入液壓油缸流量的乘積，那么，挖掘機(jī)大臂舉升緩慢多半是因輸入液壓油缸的功率減少，也就是輸入油缸的功率減少所致。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(yíng)：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，遵義水陸挖掘機(jī)租賃有哪些品牌，遵義水陸挖掘機(jī)租賃有哪些品牌，價(jià)格公道，誠(chéng)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，遵義水陸挖掘機(jī)租賃有哪些品牌。承接：大小土石方工程，歡迎咨詢洽談。

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(jiǎn)單的故障，可以通過(guò)眼看、手模、耳聽(tīng)和嗅聞等手段對(duì)零部件進(jìn)行檢查例如，通過(guò)視覺(jué)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(guò)時(shí)會(huì)有震動(dòng)地感覺(jué)，而無(wú)油液流過(guò)或壓力過(guò)低時(shí)則沒(méi)有這種現(xiàn)象。2、對(duì)換診斷法。在維修現(xiàn)場(chǎng)缺乏診斷儀器或被查元件比較精密不宜拆開(kāi)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(cè)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(cè)量來(lái)判斷該系統(tǒng)的故障點(diǎn)在一般的現(xiàn)場(chǎng)檢測(cè)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(jué);而流量的檢測(cè)則比較困難，流量的大小只可通過(guò)執(zhí)行元件動(dòng)作的快慢作出粗略的判斷。因此，在現(xiàn)場(chǎng)檢測(cè)中，更多地采用檢測(cè)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(yíng)：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(chéng)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

挖掘機(jī)故障排除：泵柱塞與缸體“咬死”。一臺(tái)HE-280型挖掘機(jī)，大修并更換液壓泵的缸體和柱塞后，液壓泵不工作并伴有異響。拆檢發(fā)現(xiàn)，柱塞與缸體黏在一起，呈“咬死”狀態(tài)。對(duì)缸體和柱塞進(jìn)行金相分析后，確認(rèn)是殘余奧氏體轉(zhuǎn)變成馬氏體，溫度越低，轉(zhuǎn)變量越大。在寒冷季節(jié)，殘余轉(zhuǎn)變?cè)诤芏痰臅r(shí)間內(nèi)即完成，致使柱塞因其體積瞬間增大而出現(xiàn)“咬死”現(xiàn)象。為此，可用**量具測(cè)量出液壓泵缸體和柱塞在室溫下的配合間隙；將缸體和柱塞分別進(jìn)行冷處理，即放在-50～-60℃的地方，30min后取出；用磨床對(duì)柱塞進(jìn)行磨削加工至室溫時(shí)的配合尺寸；對(duì)柱塞表面進(jìn)行激光淬火；用金屬**拋光膏對(duì)柱塞表面再進(jìn)行拋光處理，裝復(fù)后故障排除。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(yíng)：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(chéng)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。<span
