挖掘機(jī)上的壓力傳感器是挖掘機(jī)系統(tǒng)的核心部件，用于液壓控制，在挖掘機(jī)不斷的啟停，挖掘過程中，壓力傳感器會承受很大的壓力，所以說傳感器的耐壓，以及重復(fù)性很重要；

一臺好的挖掘機(jī)可以連續(xù)升降幾十萬次，國產(chǎn)很多挖掘機(jī)大廠，像徐工、三一重工都用日本長野計(jì)器的壓力傳感器，包括世界上的挖掘機(jī)，神鋼，卡特彼勒都是用長野NKS的。

其實(shí)國產(chǎn)的壓力傳感器挺不錯的，中國的煉鋼技術(shù)太落后，根本生產(chǎn)不出高強(qiáng)度，高可靠性的材料，所以對于挖掘機(jī)這種重型機(jī)械來說，一輛少幾十萬，都是用進(jìn)口的傳感器。

① 起動機(jī)與飛輪齒嚙合不良。齒圈與起動機(jī)齒輪在起動發(fā)動機(jī)時(shí)會發(fā)生撞擊，造成牙齒損壞或牙齒單面磨損。若牙齒連續(xù)三個以上損壞或磨損嚴(yán)重，起動機(jī)齒輪與齒圈牙齒便難以嚙合。
② 粘缸。發(fā)動機(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，冷卻后無法起動。
③ 曲軸抱死。由于潤滑系故障或缺機(jī)油造成滑動軸承干摩擦，以致終抱死曲軸而無法起動。
④ 噴油泵柱塞卡死。

⑴冬季氣候寒冷，環(huán)境溫度低，機(jī)油粘度增大，各運(yùn)動機(jī)件的摩擦阻力增加，使起動轉(zhuǎn)速降低，難以起動。
⑵蓄電池容量隨溫度下降而減少，使起動轉(zhuǎn)速進(jìn)一步降低。
⑶由于起動轉(zhuǎn)速降低，壓縮空氣滲漏增多，氣缸壁散熱量增大，致使壓縮終了時(shí)空氣的溫度和壓力大為降低，使柴油發(fā)火的延遲期增長，嚴(yán)重時(shí)甚至不能燃燒。

⑷低溫下的柴油粘度增大，使噴射速度降低，加上空氣在壓縮終了時(shí)的旋流速度、溫度和壓力都比較低，使噴入氣缸的柴油霧化質(zhì)量差，難以與空氣迅速形成良好的可燃?xì)怏w并及時(shí)發(fā)火燃燒，甚至不能著火，導(dǎo)致起動困難。

　　1、一臺挖掘機(jī)更換液壓油時(shí)，應(yīng)做如下準(zhǔn)備：購買整車液壓系統(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)一臺汽泵和大小空油桶等。準(zhǔn)備一臺正常的挖掘機(jī)。將換油的挖掘機(jī)動臂抬升到高點(diǎn)，斗桿及鏟斗收到內(nèi)點(diǎn)后發(fā)動機(jī)熄滅(動臂缸，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。
