5617481382 Bracket3、挖掘機(jī)起動(dòng)時(shí)，曲軸不能轉(zhuǎn)動(dòng)的機(jī)械故障診斷與修復(fù)發(fā)動(dòng)機(jī)起動(dòng)時(shí)，在起動(dòng)系統(tǒng)完好的情況下，按起動(dòng)開關(guān)，起動(dòng)機(jī)有響聲而曲軸不能轉(zhuǎn)動(dòng)，則屬于機(jī)械故障。引起發(fā)動(dòng)機(jī)曲軸不能轉(zhuǎn)動(dòng)的原因如下所述。
① 起動(dòng)機(jī)與飛輪齒嚙合不良。齒圈與起動(dòng)機(jī)齒輪在起動(dòng)發(fā)動(dòng)機(jī)時(shí)會(huì)發(fā)生撞擊，造成牙齒損壞或牙齒單面磨損。若牙齒連續(xù)三個(gè)以上損壞或磨損嚴(yán)重，起動(dòng)機(jī)齒輪與齒圈牙齒便難以嚙合。
② 粘缸。發(fā)動(dòng)機(jī)溫度過高時(shí)停車熄火，熱量難以散出，高溫下的活塞環(huán)與氣缸粘連，冷卻后無(wú)法起動(dòng)。
③ 曲軸抱死。由于潤(rùn)滑系故障或缺機(jī)油造成滑動(dòng)軸承干摩擦，以致終抱死曲軸而無(wú)法起動(dòng)。
④ 噴油泵柱塞卡死。

154-71-22471一、更換液壓油時(shí)準(zhǔn)備工作
　　1、一臺(tái)挖掘機(jī)更換液壓油時(shí)，應(yīng)做如下準(zhǔn)備：購(gòu)買整車液壓系統(tǒng)用的油。(液壓油箱容積的2.5倍)，濾芯，洗油，3公斤面粉，繩子，封閉液壓油管的油堵，(按換油的挖掘機(jī)上的油管配制)一臺(tái)汽泵和大小空油桶等。準(zhǔn)備一臺(tái)正常的挖掘機(jī)。將換油的挖掘機(jī)動(dòng)臂抬升到高點(diǎn)，斗桿及鏟斗收到內(nèi)點(diǎn)后發(fā)動(dòng)機(jī)熄滅(動(dòng)臂缸，斗桿缸和鏟斗缸的缸桿全部伸出到頂點(diǎn))。

　　2、液壓油箱的清洗：將箱內(nèi)的液壓油全部放出，撤出液壓濾芯，把泵和油箱之間的管路從泵的接口處拆開，放出管路內(nèi)的油液。用洗油沖洗液壓油箱和管路。用醫(yī)用沙布把液壓油箱內(nèi)部擦凈。將面粉揉和到能拉伸面的程度分成三份，用面團(tuán)分三次粘干凈液壓油箱的里面尤其是油箱的邊角處和濾芯筒。液壓油箱和濾芯筒內(nèi)清理干凈。更換新的液壓濾芯，上好蓋板。

　　3、液壓柱塞泵的沖洗：挖掘機(jī)上每種液壓柱塞泵都有沖洗油口，(放油口)。擰開上下放油口，放出泵殼內(nèi)的液壓油，擰上泵下面的油堵，從泵上面的油口向泵殼內(nèi)注滿洗油，再擰開泵下面的油堵，放出泵殼內(nèi)的洗油，反復(fù)沖洗幾次后，后用汽泵把泵殼內(nèi)的余油吹干凈后，注滿潔凈的液壓油，擰緊油堵即可。

　　4、更換泵進(jìn)油口密封圈，(O形圈)，將液壓油箱連接到泵的供油管路連接好，從液壓濾芯油口(放好更換后的濾芯)向液壓油箱內(nèi)注滿潔凈的液壓油。
