挖掘機(jī)故障的排除：動(dòng)臂提升無(wú)力且左回轉(zhuǎn)緩慢。一臺(tái)R942型液壓挖掘機(jī)的動(dòng)臂提升無(wú)力，左回轉(zhuǎn)緩慢；當(dāng)繼續(xù)作業(yè)，油溫一升高，動(dòng)臂就無(wú)法提升，同時(shí)左回轉(zhuǎn)幾乎不能轉(zhuǎn)動(dòng)。分析認(rèn)為，在其他動(dòng)作正常、主泵和主溢流閥完好的情況下，引起動(dòng)臂無(wú)力的原因可能是：①主控制閥與滑閥閥芯及閥體因磨損導(dǎo)致間隙過(guò)大，造成內(nèi)漏較大。②過(guò)載閥、補(bǔ)油閥損壞或調(diào)壓過(guò)低。③動(dòng)臂缸密封損壞導(dǎo)致內(nèi)泄。④先導(dǎo)控制油路有故障。在油溫45～55℃時(shí)，對(duì)上述4個(gè)原因逐項(xiàng)進(jìn)行了檢查，結(jié)果**項(xiàng)均沒發(fā)現(xiàn)問(wèn)題，但在檢查先導(dǎo)油路時(shí)，發(fā)現(xiàn)控制動(dòng)臂提升的先導(dǎo)閥手柄下有漏油現(xiàn)象。發(fā)動(dòng)機(jī)高速運(yùn)轉(zhuǎn)時(shí)，測(cè)得動(dòng)臂提升先導(dǎo)油I壓只有2MPa（標(biāo)準(zhǔn)值為），在這樣低的先導(dǎo)油壓控制下，自然不能將主控制閥閥芯推到行程較大的位置，因系統(tǒng)內(nèi)的流量、壓力均不夠，從而造成動(dòng)臂提升無(wú)力。解體先導(dǎo)閥后發(fā)現(xiàn)，柱塞套內(nèi)的O形密封圈已損壞。換新后試機(jī)，動(dòng)臂提升恢復(fù)正常。此外，逐項(xiàng)檢查后發(fā)現(xiàn)過(guò)載閥上的先導(dǎo)閥錐閥芯磨損嚴(yán)重。將其在高精度外圓磨床上修磨后，裝機(jī)試驗(yàn)，左、右回轉(zhuǎn)都恢復(fù)正常。

挖掘機(jī)維修不能做的事。螺栓擰得太緊。工程機(jī)械在拆裝過(guò)程中，很多部位的螺栓都是有標(biāo)準(zhǔn)轉(zhuǎn)矩要求的，比如傳動(dòng)箱、汽缸蓋、輪轂、連桿和前橋等部位，擰緊力矩在說(shuō)明書中都有專門規(guī)定，切不可隨意改變。但是很多使用人員都誤認(rèn)為緊一些會(huì)較好，但是擰得太緊會(huì)造成螺釘或螺栓折斷，也可能由于螺紋滑扣而引起故障。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。
