裝載機變速箱液壓系統壓力不足是怎么回事？該如何處理呢？
在很(hen)多(duo)建筑物外架、礦山(shan)開(kai)采等區(qu)域，想要(yao)大批(pi)的(de)裝卸(xie)(xie)機(ji)（別名堆高機(ji)）家(jia)庭作業。他們裝卸(xie)(xie)機(ji)大部(bu)分(fen)采取液(ye)力廠家(jia)廠傳動(dong)齒輪(lun)裝置(zhi)，其辦公(gong)基本(ben)方式(shi)與新汽車電腦(nao)自(zi)動(dong)分(fen)動(dong)箱(xiang)(xiang)箱(xiang)(xiang)器類同。該(gai)分(fen)動(dong)箱(xiang)(xiang)箱(xiang)(xiang)箱(xiang)(xiang)在使(shi)用中的(de)一(yi)些常見的(de)故障率是手動(dong)油(you)壓機(ji)式(shi)系統(tong)軟件化(hua)學習安(an)全閥(fa)過低可(ke)能(neng)還沒有學習心理壓力差，裝卸(xie)(xie)機(ji)難以安(an)裝驅動(dong)。今兒(er)，人們將定量分(fen)析手動(dong)油(you)壓機(ji)式(shi)廠家(jia)廠傳動(dong)齒輪(lun)裝置(zhi)手動(dong)油(you)壓機(ji)式(shi)系統(tong)軟件化(hua)的(de)辦公(gong)基本(ben)方式(shi)和學習心理壓力差存在問題(ti)(ti)的(de)問題(ti)(ti)。
第(di)一，我們的(de)來瞧看變速(su)器箱(xiang)液壓機(ji)平臺和油配置規(gui)劃的(de)展示圖。
齒圈箱的油(you)(you)存儲在齒圈箱的邊側。打火機(ji)啟車時(shi)，飛輪(lun)起到液(ye)力變矩器泵(beng)輪(lun)快(kuai)速路滑動(dong)。泵(beng)輪(lun)起到軸齒圈起到調速泵(beng)滑動(dong)。手動(dong)液(ye)壓機(ji)多(duo)路閥(fa)油(you)(you)從(cong)油(you)(you)底(di)殼中被吸出。經調速泵(beng)施壓后(hou)（重(zhong)壓可(ke)達(da)到1.5MPa上），開(kai)始(shi)(shi)手動(dong)液(ye)壓機(ji)多(duo)路閥(fa)油(you)(you)濾水(shui)程序器，濾水(shui)程序后(hou)的手動(dong)液(ye)壓機(ji)多(duo)路閥(fa)油(you)(you)開(kai)始(shi)(shi)排壓閥(fa)。
釋壓(ya)(ya)方法(fa)閥中，壓(ya)(ya)油(you)兵劃(hua)分成(cheng)兩(liang)路口，五路相連(lian)液力(li)變(bian)(bian)矩器(qi)(qi)，液力(li)變(bian)(bian)矩器(qi)(qi)身為變(bian)(bian)矩器(qi)(qi)的(de)(de)做工作有機溶劑，將(jiang)打著機的(de)(de)趨勢(shi)傳達著給(gei)變(bian)(bian)檔(dang)箱中的(de)(de)齒圈(quan)(quan)傳驅力(li)構。來自于(yu)變(bian)(bian)矩器(qi)(qi)的(de)(de)負壓(ya)(ya)油(you)經油(you)壓(ya)(ya)機油(you)cpu風冷散(san)熱(re)器(qi)(qi)散(san)熱(re)釋壓(ya)(ya)方法(fa)后，借助離(li)合器(qi)(qi)踏板(ban)平臺的(de)(de)通孔進(jin)(jin)齒圈(quan)(quan)箱，潤滑系統小行星(xing)齒圈(quan)(quan)結構特征，如果流進(jin)(jin)油(you)底殼；
另路工(gong)(gong)(gong)作(zuo)重(zhong)壓(ya)(ya)(ya)差油(you)(you)能(neng)(neng)夠剎(cha)車切割閥(fa)(fa)進人換(huan)檔(dang)(dang)(dang)(dang)閥(fa)(fa)。駕使(shi)員能(neng)(neng)夠操縱換(huan)檔(dang)(dang)(dang)(dang)閥(fa)(fa)桿的(de)所在(zai)(zai)區域，使(shi)工(gong)(gong)(gong)作(zuo)重(zhong)壓(ya)(ya)(ya)差油(you)(you)進人有差異(yi) 的(de)剎(cha)車柱(zhu)塞缸，使(shi)有差異(yi) 檔(dang)(dang)(dang)(dang)位的(de)剎(cha)車聯系相處去，使(shi)自動擋變速箱箱轉換(huan)到(dao)有差異(yi) 的(de)檔(dang)(dang)(dang)(dang)位（一樣只剩下倒檔(dang)(dang)(dang)(dang)、當(dang)和二檔(dang)(dang)(dang)(dang)二個(ge)檔(dang)(dang)(dang)(dang)位）。當(dang)轉換(huan)到(dao)空檔(dang)(dang)(dang)(dang)時，很多工(gong)(gong)(gong)作(zuo)重(zhong)壓(ya)(ya)(ya)差油(you)(you)同一真接流向油(you)(you)底(di)，工(gong)(gong)(gong)作(zuo)重(zhong)壓(ya)(ya)(ya)差油(you)(you)也(ye)會進人緩解氣壓(ya)(ya)(ya)閥(fa)(fa)的(de)倆測。能(neng)(neng)夠液壓(ya)(ya)(ya)平衡點(dian)，各式各樣操縱軟件液壓(ya)(ya)(ya)，使(shi)軟件液壓(ya)(ya)(ya)安全(quan)穩(wen)定在(zai)(zai)1.1～1.5MPa相互之間。軟件的(de)工(gong)(gong)(gong)作(zuo)重(zhong)壓(ya)(ya)(ya)差傳紅(hong)外(wai)感應器(qi)器(qi)也(ye)按照在(zai)(zai)該(gai)所在(zai)(zai)區域，它將(jiang)工(gong)(gong)(gong)作(zuo)重(zhong)壓(ya)(ya)(ya)差數據傳遞到(dao)電子儀表板上的(de)工(gong)(gong)(gong)作(zuo)重(zhong)壓(ya)(ya)(ya)差表，是為了駕使(shi)員立即(ji)看(kan)軟件的(de)工(gong)(gong)(gong)作(zuo)重(zhong)壓(ya)(ya)(ya)差。
在這些(xie)體系中，有一些(xie)主閥。
1液(ye)壓裝置(zhi)軟(ruan)件(jian)(jian)(jian)軟(ruan)件(jian)(jian)(jian)系(xi)(xi)統(tong)(tong)軟(ruan)件(jian)(jian)(jian)軟(ruan)件(jian)(jian)(jian)系(xi)(xi)統(tong)(tong)油(you)泵(beng)油(you)空(kong)氣濾(lv)(lv)芯(xin)(xin)(xin)器(qi)旁通閥(fa)：該閥(fa)按裝在液(ye)壓裝置(zhi)軟(ruan)件(jian)(jian)(jian)軟(ruan)件(jian)(jian)(jian)系(xi)(xi)統(tong)(tong)軟(ruan)件(jian)(jian)(jian)軟(ruan)件(jian)(jian)(jian)系(xi)(xi)統(tong)(tong)油(you)泵(beng)油(you)空(kong)氣濾(lv)(lv)芯(xin)(xin)(xin)器(qi)的頂蓋起來。當液(ye)壓裝置(zhi)軟(ruan)件(jian)(jian)(jian)軟(ruan)件(jian)(jian)(jian)系(xi)(xi)統(tong)(tong)軟(ruan)件(jian)(jian)(jian)軟(ruan)件(jian)(jian)(jian)系(xi)(xi)統(tong)(tong)油(you)泵(beng)油(you)空(kong)氣濾(lv)(lv)芯(xin)(xin)(xin)器(qi)堵住了時，為杜絕軟(ruan)件(jian)(jian)(jian)軟(ruan)件(jian)(jian)(jian)系(xi)(xi)統(tong)(tong)中的油(you)剪斷，點擊單向閥(fa)，使液(ye)壓裝置(zhi)軟(ruan)件(jian)(jian)(jian)軟(ruan)件(jian)(jian)(jian)系(xi)(xi)統(tong)(tong)軟(ruan)件(jian)(jian)(jian)軟(ruan)件(jian)(jian)(jian)系(xi)(xi)統(tong)(tong)油(you)泵(beng)油(you)沒經濾(lv)(lv)出同(tong)時啟閉(bi)軟(ruan)件(jian)(jian)(jian)軟(ruan)件(jian)(jian)(jian)系(xi)(xi)統(tong)(tong)。似(si)的事(shi)情下，該閥(fa)的啟閉(bi)工作壓力約為1.1MPa
2液(ye)(ye)力變(bian)矩器(qi)(qi)整體平(ping)(ping)安(an)閥：在通往液(ye)(ye)力變(bian)矩器(qi)(qi)的(de)油(you)水分離(li)器(qi)(qi)有有一個整體平(ping)(ping)安(an)閥。其(qi)啟動(dong)負擔基(ji)本上為0.3～0.45MPa。其(qi)意義(yi)是(shi)盡量不要(yao)液(ye)(ye)力變(bian)矩器(qi)(qi)內液(ye)(ye)壓過(guo)高，護理液(ye)(ye)力變(bian)矩器(qi)(qi)的(de)平(ping)(ping)安(an)
3研磨(mo)調壓閥：液力油從變矩器(qi)散熱片(pian)器(qi)排出后，必須要進入換(huan)擋(dang)器(qi)對行星齒輪系統傳動系統系統對其進行研磨(mo)。這段時(shi)間，壓差(cha)(cha)不能過高，不然換(huan)擋(dang)箱(xiang)的封口(kou)將困難重重。因，在此快速設(she)置(zhi)研磨(mo)調壓閥，其關閉壓差(cha)(cha)一(yi)般的在0.1~0.2MPa區間內，以減少研磨(mo)油閥壓差(cha)(cha)過高
4離(li)合片立即斷掉閥：該(gai)閥連(lian)接(jie)在(zai)(zai)(zai)換(huan)檔(dang)閥剎(cha)車器總成上。其用(yong)處(chu)是(shi)在(zai)(zai)(zai)剎(cha)車設(she)備空(kong)壓力(li)(li)(li)表(biao)力(li)(li)(li)表(biao)缺陷、踩下剎(cha)車器時，主動立即斷掉至(zhi)換(huan)檔(dang)閥的(de)心理(li)(li)壓力(li)(li)(li)油，使(shi)換(huan)擋器箱(xiang)器設(she)置(zhi)成到(dao)空(kong)檔(dang)。另管理(li)(li)等方面(mian)(mian)做到(dao)穩定維(wei)護用(yong)處(chu)，逃(tao)(tao)避在(zai)(zai)(zai)剎(cha)車設(she)備空(kong)壓力(li)(li)(li)表(biao)力(li)(li)(li)表(biao)缺陷的(de)狀態下掛檔(dang)行駛的(de)，從而造成空(kong)壓力(li)(li)(li)表(biao)力(li)(li)(li)表(biao)缺陷而會導(dao)致(zhi)剎(cha)車不可(ke)用(yong)；另另管理(li)(li)等方面(mian)(mian)，在(zai)(zai)(zai)剎(cha)車設(she)備工做時，換(huan)擋器箱(xiang)箱(xiang)設(she)置(zhi)成到(dao)空(kong)檔(dang)，以逃(tao)(tao)避換(huan)擋器箱(xiang)箱(xiang)持續時間傷害趨勢(shi)，這與駕車員的(de)駕車企圖相爭端。
要學(xue)(xue)習(xi)(xi)(xi)真空學(xue)(xue)習(xi)(xi)(xi)工(gong)作壓(ya)力(li)表(biao)屏幕上凸(tu)顯體統(tong)學(xue)(xue)習(xi)(xi)(xi)學(xue)(xue)習(xi)(xi)(xi)工(gong)作壓(ya)力(li)達不(bu)(bu)到1.0MPa或(huo)必然不(bu)(bu)屏幕上凸(tu)顯學(xue)(xue)習(xi)(xi)(xi)學(xue)(xue)習(xi)(xi)(xi)工(gong)作壓(ya)力(li)，則(ze)運載機始終不(bu)(bu)能行車還(huan)始終不(bu)(bu)能自動運行。故障率(lv)的大部分情況(kuang)內(nei)容(rong)如下：
1加速(su)箱氣(qi)動(dong)油匱乏，或氣(qi)動(dong)油不一(yi)致(zhi)合規(gui)定(ding)基準。一(yi)般(ban)來說實際情(qing)況下(xia)，這(zhe)樣加速(su)箱就必須(xu)采(cai)用(yong)規(gui)定(ding)的氣(qi)動(dong)油，如16號氣(qi)動(dong)鏈(lian)傳動(dong)油或制造(zao)技(ji)術廠規(gui)定(ding)的氣(qi)動(dong)油。不能用(yong)正(zheng)規(gui)氣(qi)動(dong)油代換。
2油底殼中的氣動(dong)油空(kong)(kong)氣濾(lv)蕊(rui)(rui)器濾(lv)蕊(rui)(rui)閉塞(sai)，導至(zhi)經由的氣動(dong)油過(guo)少(shao)。這樣濾(lv)蕊(rui)(rui)往往是鋁(lv)合(he)(he)金(jin)網活性炭吸附器。最經常見的的故障問題(ti)是氣動(dong)油濾(lv)蕊(rui)(rui)長周期不改換，接觸面(mian)被各方面(mian)雜物、膠質、鋁(lv)合(he)(he)金(jin)碎末等閉塞(sai)，更神(shen)奇的是，在(zai)拆(chai)裝變(bian)檔箱后(hou)，油底殼里留有(you)打了(le)個塊棉(mian)布(bu)。汽車發(fa)思想一運行的，棉(mian)布(bu)就(jiu)活性炭吸附在(zai)氣動(dong)油空(kong)(kong)氣濾(lv)蕊(rui)(rui)器濾(lv)蕊(rui)(rui)上。汽車發(fa)思想停(ting)穩來(lai)后(hou)，又沒了(le)算來(lai)。此(ci)誤(wu)區打擊了(le)自己二天。
3從油(you)底殼到加速泵的軟管有漏氣或的內部外(wai)皮擠(ji)壓(ya)傷(shang)和側(ce)壁(bi)(bi)。氣氛(fen)泄密(mi)會(hui)以至于(yu)(yu)加速泵吸油(you)過高甚至會(hui)無(wu)吸油(you)。側(ce)壁(bi)(bi)會(hui)以至于(yu)(yu)氣動(dong)油(you)閥(fa)窄小(xiao)，以至于(yu)(yu)氣動(dong)系(xi)統的壓(ya)力值過高。
4加(jia)速泵(beng)(beng)已(yi)丟失(shi)(shi)或(huo)過重磨花(hua)，以至于壓力差欠缺(que)。或(huo)加(jia)速泵(beng)(beng)傳動系(xi)統貸款(kuan)機(ji)構（軸(zhou)齒圈(quan)）已(yi)丟失(shi)(shi)，加(jia)速泵(beng)(beng)不(bu)允(yun)許轉動或(huo)者單方(fang)向轉動。最喜歡見的(de)誘因是(shi)軸(zhou)齒圈(quan)內(nei)的(de)花(hua)鍵(jian)磨花(hua)過大，就(jiu)沒(mei)有辦法驅使加(jia)速泵(beng)(beng)。
5液壓機油(you)柴油(you)濾(lv)清器旁通(tong)閥(fa)賭塞。這(zhe)一(yi)，旁通(tong)閥(fa)的(de)做用(yong)是(shi)以防(fang)過濾(lv)程(cheng)序器賭塞和終止泵油(you)，但這(zhe)樣旁通(tong)閥(fa)損害，結論恰恰恰反向。一(yi)起(qi)，旁通(tong)閥(fa)閥(fa)芯脫落情(qing)況，賭塞在進氣(qi)(qi)軟管內。那時候我感覺到進氣(qi)(qi)軟管出了事(shi)情(qing)，但找不超過問題(ti)點。之(zhi)后(hou)，撤換一(yi)根新的(de)進氣(qi)(qi)軟管，避(bi)免了問題(ti)。拆換舊進氣(qi)(qi)軟管之(zhi)后(hou)發現被(bei)閥(fa)芯賭塞。
6宣(xuan)泄閥壓縮彈簧片力過低(di)或壓縮彈簧片斷裂現象，會造成宣(xuan)泄閥位于常開(kai)情形，不可能建造系統阻力。
7汽(qi)車液(ye)壓離合片關閉閥(fa)保持油(you)嘴關閉形態(tai)。種(zhong)斷塊在(zai)東北地區春(chun)夏(xia)(xia)季很多見。汽(qi)車液(ye)壓離合片關閉閥(fa)處(chu)有兩人新(xin)鮮(xian)室(shi)內空氣管(guan)。基于裝運機(ji)的液(ye)壓潮濕傳動裝置中不收縮新(xin)鮮(xian)室(shi)內空氣潮濕。在(zai)汽(qi)車液(ye)壓離合片關閉閥(fa)中凝聚濕熱后(hou)，在(zai)春(chun)夏(xia)(xia)季會凍住(zhu)，使汽(qi)車液(ye)壓離合片關閉閥(fa)卡滯。在(zai)種(zhong)時候下，但凡拆下來、衛生、軸承潤滑油(you)高壓閥(fa)門(men)
