引起挖掘機(jī)輸入油缸的功率減小的原因有：1油泵的影響根據(jù)油缸內(nèi)的活塞移動(dòng)速度與進(jìn)入油缸油液的工作流量成正比關(guān)系，如果液壓油泵輸出的流量減少，必然會(huì)使大臂油缸舉升緩慢。進(jìn)而分析，油泵的實(shí)際流量等于油泵的理論流量與總效率的乘積（油泵容積效率與機(jī)械效率之和）如果油泵的總效率減小，凱里大型挖掘機(jī)租賃施工隊(duì)伍，則油泵實(shí)際流量也必然在減小。使油泵總效率減小的主要原因是:油泵泄漏量增大和機(jī)械摩擦損失增大。2油缸的影響液壓油缸活塞密封圈損壞、油缸拉傷、油缸蓋密封圈損壞而引起油液竄腔或漏油，使油缸內(nèi)的容積效率減小，即油缸本身效率減小，故輸出的功率減小，其表現(xiàn)為動(dòng)臂舉升速度緩慢。3油路泄漏的影響油泵的吸程段（油泵至油箱）管路密封不良而吸入空氣，影響泵油效率；油泵至油缸的壓程段向系統(tǒng)外漏油或通過(guò)操縱閥漏回油箱，均會(huì)使進(jìn)入油缸的油液流量減小，壓力降低，導(dǎo)致動(dòng)臂舉升緩慢。4油路堵塞的影響液壓系統(tǒng)的工作油液一般會(huì)有機(jī)械雜質(zhì)，凱里大型挖掘機(jī)租賃施工隊(duì)伍，這些雜質(zhì)在油路中的流油載面小的部位堵塞，使進(jìn)入油缸油液流量減小，同時(shí)還會(huì)引起壓力降低。因此，致使油缸輸出功率減小而使大臂舉升緩慢，凱里大型挖掘機(jī)租賃施工隊(duì)伍。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，歡迎咨詢洽談。

挖掘機(jī)維修不能做的事。缸套和活塞新品不經(jīng)選配即安裝。在換裝汽缸套和活塞時(shí)，以為新的汽缸套和活塞都是標(biāo)準(zhǔn)件，都具有互換性，裝上去就能夠用了。實(shí)際上，汽缸套與活塞的尺寸都會(huì)有公差范圍。如果把大尺度的汽缸套配上小尺度的活塞，會(huì)使合作空隙過(guò)大，形成緊縮無(wú)力，啟動(dòng)會(huì)比較困難。因而，換裝時(shí)需要查看標(biāo)準(zhǔn)缸套與活塞的尺寸分組代號(hào)，裝用的缸套和活塞有使標(biāo)準(zhǔn)活塞的尺寸分組代號(hào)與標(biāo)準(zhǔn)缸套的尺寸分組代號(hào)相同，只要這樣才干確保兩者之間具有規(guī)范的合作空隙。此外，各缸裝用同一分組代號(hào)的缸套和活塞的一起，還要留意裝前查驗(yàn)缸塞空隙，為了確保裝置規(guī)范，在裝機(jī)前還應(yīng)進(jìn)行一次檢測(cè)，以防裝上假冒偽劣的殘次品。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。

挖機(jī)維修時(shí)有些事千萬(wàn)不能做！黃油的亂用亂涂。汽缸墊上涂黃油。黃油是工程機(jī)械維修中常用的潤(rùn)滑脂，可起到潤(rùn)滑和密封的效果。因而，有些維修工在裝置汽缸墊時(shí)，就會(huì)在汽缸墊上涂上一層黃油，以為這樣能夠增加柴油機(jī)的密封性。殊不知，這樣做反而影響了柴油機(jī)的工作功能。汽缸墊是柴油機(jī)缸體與缸蓋之間很重要的密封件，它不但能密封汽缸內(nèi)所發(fā)生的高溫高壓氣體，并且還能密封汽缸蓋和缸體內(nèi)的的冷卻水和潤(rùn)滑油，所以在拆裝汽缸墊時(shí)，都要特別留意它的密封質(zhì)量。假如裝置時(shí)在汽缸墊上涂黃油，當(dāng)汽缸蓋螺栓擰緊時(shí)，一部分黃油就會(huì)被擠壓到汽缸水道和油道中。留在缸墊間的黃油在汽缸工作時(shí)，由于受高溫影響，一部分會(huì)流入汽缸焚燒；另一部分則殘留在缸體與缸蓋的結(jié)合面上，使缸墊、缸蓋與機(jī)體平面之間有了縫隙，高溫高壓燃?xì)夂茌p易從此處沖擊汽缸墊，毀壞缸墊，形成漏氣。此外，黃油長(zhǎng)期處在高溫狀態(tài)下還會(huì)發(fā)生積炭，形成缸墊過(guò)早老化變質(zhì)。因而裝置汽缸墊時(shí)切勿涂抹黃油。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。承接：大小土石方工程，歡迎咨詢洽談。
