挖掘機(jī)故障的排除：動臂提升無力且左回轉(zhuǎn)緩慢。一臺R942型液壓挖掘機(jī)的動臂提升無力，左回轉(zhuǎn)緩慢；當(dāng)繼續(xù)作業(yè)，油溫一升高，動臂就無法提升，同時(shí)左回轉(zhuǎn)幾乎不能轉(zhuǎn)動。分析認(rèn)為，在其他動作正常、主泵和主溢流閥完好的情況下，引起動臂無力的原因可能是：①主控制閥與滑閥閥芯及閥體因磨損導(dǎo)致間隙過大，造成內(nèi)漏較大。②過載閥、補(bǔ)油閥損壞或調(diào)壓過低。③動臂缸密封損壞導(dǎo)致內(nèi)泄。④先導(dǎo)控制油路有故障。在油溫45～55℃時(shí)，對上述4個原因逐項(xiàng)進(jìn)行了檢查，結(jié)果**項(xiàng)均沒發(fā)現(xiàn)問題，但在檢查先導(dǎo)油路時(shí)，發(fā)現(xiàn)控制動臂提升的先導(dǎo)閥手柄下有漏油現(xiàn)象。發(fā)動機(jī)高速運(yùn)轉(zhuǎn)時(shí)，測得動臂提升先導(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，從而造成動臂提升無力。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)，動臂提升恢復(fù)正常。此外，逐項(xiàng)檢查后發(fā)現(xiàn)過載閥上的先導(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。
