●KCB齒輪(lun)泵(beng)常見(jian)故障(zhang)及解決方(fang)法

    目(mu)前,KCB齒(chi)輪泵(kcb不(bu)鏽(xiu)鋼齒(chi)輪泵(beng))在自卸汽(qi)車與(yu)工程機械(xie)操縱(zong)機(ji)構(gou)中運(yun)用較多(duo),現(xian)将其(qi)常見故障(zhang)及除(chu)方法(fa)介(jie)紹(shao)如下(xia),供參(can)考。   

  1、産生振動(dong)與(yu)噪聲(sheng)的原因

  

  (2)機(ji)械原因

   ①泵與聯(lian)軸器的連(lian)接因(yin)不合(he)規定要求而産(chan)生振動及噪聲(sheng)。應按規(gui)定(ding)要求調整(zheng)聯軸器。   

   ②因油中(zhong)污物(wu)進入(ru)泵内導緻(zhi)齒輪等部(bu)件磨損拉(la)傷而(er)産生(sheng)噪聲。應(ying)更(geng)換油(you)液,加(jia)強(qiang)過濾,拆(chai)開泵(beng)清(qing)洗;對磨(mo)損嚴(yan)重的齒輪(lun),須修理或(huo)更換(huan)。   

   ③泵内零件(jian)損壞(huai)或(huo)磨損嚴重将(jiang)産生(sheng)振動(dong)與噪(zao)聲:如(ru)齒形誤差或(huo)周(zhou)節誤(wu)差大,兩齒(chi)輪接(jie)觸不(bu)良,齒面粗(cu)糙度(du)高(gao),公法線(xian)長度超差,齒側(ce)隙過(guo)小(xiao),兩(liang)齧合(he)齒輪(lun)的(de)接觸區(qu)不在分(fen)度(du)圓位(wei)置等。此時(shi),可更(geng)換齒輪或(huo)将齒(chi)輪對(dui)研。同時,軸(zhou)承的滾(gun)針保持(chi)架破(po)損、長(zhang)短軸(zhou)軸頸(jing)及(ji)滾(gun)針磨損等(deng),均可(ke)導緻(zhi)軸承(cheng)旋(xuan)轉(zhuan)不暢(chang)而産生機(ji)械噪(zao)聲,此時(shi)需(xu)拆修齒輪(lun)泵,更換滾(gun)針軸承。   

   ④KCB齒輪泵(kcb不(bu)鏽鋼齒(chi)輪泵(beng))齒(chi)輪(lun)軸向(xiang)裝配(pei)間(jian)隙過小(xiao);齒輪端面(mian)與前後端(duan)蓋之間的(de)滑動(dong)接合面因(yin)齒輪在(zai)裝(zhuang)配前(qian)毛刺未能仔細清除(chu),從而運轉(zhuan)時拉傷接合面(mian),使内(nei)洩漏(lou)大,導(dao)緻輸出流(liu)量減(jian)少;污物進入泵(beng)内并(bing)楔入(ru)齒輪端面與前後端(duan)蓋之間(jian)的(de)間隙(xi)内拉(la)傷(shang)配(pei)合面(mian),導緻高低(di)壓腔因出(chu)現徑向拉(la)傷的(de)溝槽而連(lian)通,使(shi)輸出(chu)流量(liang)減小(xiao)。對上述情(qing)況應(ying)分(fen)别(bie)采用(yong)以下措施(shi)修複(fu)。拆解(jie)齒輪泵,适(shi)當地(di)加大(da)軸向間隙(xi)即研磨齒(chi)輪的(de)端(duan)面;用平(ping)面磨床磨平前(qian)後蓋(gai)端面和齒(chi)輪端(duan)面,并清除(chu)輪齒上的(de)毛刺(ci)(不能(neng)倒(dao)角);經平(ping)面磨(mo)削後(hou)的前後端(duan)蓋其(qi)端面(mian)上卸荷(he)槽(cao)的深(shen)度尺(chi)寸會有變(bian)化,應(ying)适(shi)當(dang)增加寬度(du)。   

  (3)其他(ta)原因   

   油液(ye)的黏(nian)度(du)高也會(hui)産生(sheng)噪(zao)聲,必須(xu)選用(yong)黏度合适(shi)的油(you)液。   

  2、KCB齒(chi)輪泵(beng)(kcb不鏽鋼齒(chi)輪泵)輸出(chu)流量(liang)不足(zu)   

   ①油溫(wen)高将使其(qi)黏度下降(jiang)、内(nei)洩漏增(zeng)加,使泵(beng)輸(shu)出流(liu)量減(jian)小(xiao)。應查明(ming)原因采取(qu)措施(shi);對于(yu)中(zhong)高壓齒(chi)輪泵,須檢(jian)查密(mi)封圈(quan)是否破損(sun)。   

   ②選用油的(de)黏度(du)過高或過(guo)低,均(jun)會(hui)造(zao)成泵的輸(shu)出(chu)流量減(jian)少,應(ying)使用(yong)黏度(du)合格(ge)的(de)油(you)品。   

   ③KCB齒(chi)輪泵(beng)一般(ban)不可(ke)以反(fan)轉,如(ru)泵體裝反(fan),将造(zao)成壓油腔與吸(xi)油腔(qiang)局部(bu)短接(jie),使其流(liu)量減少(shao)甚至(zhi)吸不(bu)上油來。此時,應查泵(beng)的轉(zhuan)向。   

   ④發(fa)動機轉速(su)不夠(gou),造成流量(liang)減小(xiao)。應查明(ming)原因并(bing)加以(yi)除。   

  3、旋轉不(bu)暢   

   ①軸(zhou)向間隙或徑向間隙(xi)太小。重新(xin)加以調(diao)整(zheng)修配(pei)   

   ②泵内(nei)有污(wu)物。解體以清除異物。   

   ③裝配(pei)有誤。齒(chi)輪(lun)泵兩(liang)銷孔(kong)的加(jia)工基(ji)準面(mian)并非(fei)裝配(pei)基準(zhun)面,如先将(jiang)銷子打入(ru),再擰緊螺釘,泵(beng)會轉(zhuan)不動。正确(que)的方法是(shi),邊(bian)轉動齒(chi)輪泵邊擰緊螺釘,配(pei)鑽(zuan)銷孔并(bing)打入(ru)銷(xiao)子(zi)。   

   ④泵與(yu)發動(dong)機聯(lian)軸器(qi)的同(tong)軸度(du)差。同軸度(du)應保(bao)證在0.1mm以(yi)内。   

   ⑤泵内零件(jian)未退(tui)磁。裝配(pei)前(qian)所有(you)零件均(jun)須(xu)退磁(ci)。   

   ⑥滾(gun)針套質(zhi)量不合(he)格或滾(gun)針斷裂。修(xiu)理或(huo)更換。   

   ⑦工作(zuo)油輸出口被堵塞。清(qing)除(chu)異物。   

  4、發熱

  ①造(zao)成齒(chi)輪(lun)泵(beng)旋轉(zhuan)不暢(chang)的(de)各項原(yuan)因均能導緻齒(chi)輪泵(beng)發熱(re),除方(fang)法亦(yi)可參(can)照其(qi)執行。   

   ②油液(ye)黏度(du)過(guo)高或過(guo)低。重(zhong)新(xin)選(xuan)油。   

   ③側(ce)闆、軸(zhou)套與(yu)齒輪端面嚴重(zhong)摩擦(ca)。修複或更(geng)換。   

   ④環(huan)境溫(wen)度高(gao),油箱容積(ji)小,散(san)熱不良,都(dou)會使(shi)泵發(fa)熱。應(ying)分别處理(li)。   

  5、KCB齒輪(lun)泵(kcb不鏽鋼(gang)齒輪泵)主要零(ling)件的(de)修(xiu)複   

  (1)齒輪   

   ①齒形(xing)修理(li):用細砂布(bu)或油(you)石(shi)除(chu)去拉(la)傷或(huo)已磨成多(duo)棱形(xing)的部位,再(zai)将齒(chi)輪齧(nie)合面(mian)調換方(fang)位(wei)并适當地進(jin)行(hang)對研(yan),清洗幹淨(jing);對用(yong)肉眼能觀察到(dao)的嚴重磨(mo)損件(jian),應予(yu)以更換。   

   ②端面(mian)修(xiu)理:齒輪端(duan)面由(you)于與(yu)軸承座或(huo)前後(hou)蓋相(xiang)對(dui)轉動而(er)磨損(sun),輕時(shi)會起(qi)線,可(ke)用研(yan)磨方(fang)法将(jiang)起線(xian)毛刺(ci)痕迹研(yan)去并抛(pao)光;磨損(sun)嚴(yan)重時,應将(jiang)齒(chi)輪放在(zai)平面(mian)磨床上進(jin)行修(xiu)磨。應(ying)注意(yi):兩個(ge)齒(chi)輪(lun)必須(xu)同時(shi)放(fang)在平面(mian)磨床上進(jin)行修磨,目的是(shi)為了(le)保證(zheng)兩個(ge)齒輪(lun)的厚度差在5μm範(fan)圍内;同(tong)時(shi)必須保證端面與孔(kong)的垂(chui)直度及兩(liang)端面(mian)的(de)平(ping)行度(du)均在(zai)5μm範圍内,并用油石将銳邊(bian)倒鈍(dun),但(dan)切(qie)不可倒角,做(zuo)到(dao)無毛(mao)刺、飛邊(bian)即(ji)可。   

   ③當齒輪(lun)的齧(nie)合表(biao)面磨(mo)損時(shi),應用(yong)油(you)石将磨(mo)損所(suo)産(chan)生(sheng)的毛(mao)刺去(qu)掉;同時,調(diao)換齒(chi)輪(lun)的齧合(he)方位,使(shi)原來不(bu)齧合工作(zuo)的齒(chi)形表面進行齧(nie)合工作(zuo),這(zhe)樣不僅能保(bao)證其原(yuan)有的工作(zuo)性能(neng),還能(neng)延(yan)長(zhang)齒輪(lun)的工作(zuo)壽(shou)命。   

  (2)KCB齒(chi)輪泵(kcb不鏽(xiu)鋼齒(chi)輪(lun)泵)泵體(ti)   

   泵體的磨(mo)損,主(zhu)要在(zai)内腔(qiang)與齒(chi)輪(lun)項圓相(xiang)接觸的那(na)一面,且多(duo)發生在吸(xi)油側。如果(guo)泵體屬于(yu)對稱(cheng)型,可(ke)将泵(beng)體(ti)翻(fan)轉180度(du)後再用(yong);如果泵(beng)體屬于非對稱型,則需采用電(dian)鍍青(qing)銅合金工(gong)藝或(huo)電刷(shua)鍍的(de)方法修複(fu)泵體内腔孔(kong)的磨損(sun)部位。   

  (3)軸承(cheng)座圈   

   軸承(cheng)座圈(quan)的磨(mo)損一般在與(yu)齒輪接(jie)觸的(de)那(na)一(yi)端面(mian)和與(yu)滾針接觸(chu)的内孔(kong)上(shang)。端面(mian)磨損(sun)或拉(la)毛起(qi)線時,可将4個軸(zhou)承座(zuo)圈(quan)放在平(ping)面磨床(chuang)上,以不與齒輪接觸的(de)那一面為基準(zhun)将拉(la)毛端面磨(mo)平,其(qi)精度(du)應保證在(zai)10μm範圍(wei)内。軸(zhou)承座圈一般磨損較小,若(ruo)磨損(sun)嚴重,可研(yan)磨;或(huo)适當(dang)地加大孔(kong)徑并(bing)重新(xin)選配(pei)滾針(zhen);或(huo)更換軸(zhou)承座圈。   

  (4)長(zhang)、短軸(zhou)   

   長、短(duan)軸的(de)失效(xiao),主要(yao)是在與滾(gun)針軸(zhou)承相接觸處出(chu)現磨(mo)損。如(ru)果磨(mo)損輕微,可(ke)采用(yong)抛光(guang)修(xiu)複(fu)(并更(geng)換新(xin)的滾針軸承);如(ru)果(guo)磨損嚴(yan)重或(huo)折(she)斷(duan),則需用鍍(du)鉻(ge)工(gong)藝修(xiu)複,或重新(xin)加工(gong)。重新加工時,須(xu)滿足長(zhang)、短(duan)軸上(shang)的鍵(jian)槽對(dui)軸心(xin)線的平行度和對稱(cheng)度的要求(qiu);裝在軸(zhou)上(shang)的平(ping)鍵與(yu)齒(chi)輪鍵槽(cao)的配(pei)合間(jian)隙均(jun)不能過大(da);軸不(bu)得在(zai)齒輪(lun)内孔(kong)産生徑(jing)向(xiang)擺動(dong);軸頸與安裝齒(chi)輪部(bu)分配合表(biao)面的同(tong)軸度不(bu)得大(da)于10μm,兩端軸(zhou)頸的(de)同軸(zhou)度不(bu)得超(chao)過20-30μm。

  kcb齒(chi)輪泵作用是将(jiang)機油提高(gao)到一(yi)定壓力後(hou),強制(zhi)地壓送(song)到(dao)發動(dong)機各(ge)零件的運動表(biao)面上。其結(jie)構多采用(yong)齒輪(lun)式機油泵(beng)。發動(dong)機工作時,曲軸(zhou)帶動(dong)主動齒輪(lun)傳動,被(bei)動(dong)齒輪(lun)作反(fan)方向旋轉(zhuan)。吸油腔(qiang)内的機(ji)油便(bian)沿着齒隙(xi)和泵(beng)壁壓(ya)入出(chu)油腔。因吸油腔(qiang)内的機油(you)被不(bu)斷帶走(zou),故吸油(you)腔内産(chan)生(sheng)吸力(li),不斷地将(jiang)油底(di)殼内(nei)的(de)機(ji)油吸入吸(xi)油腔,并同(tong)時将(jiang)一定壓力(li)的機(ji)油泵入潤(run)滑油路。

   齒(chi)輪油泵是(shi)借一(yi)對相互(hu)齧(nie)合的(de)齒輪,将(jiang)機械能(neng)轉換為油(you)壓能(neng)的裝(zhuang)置(zhi)。在空壓(ya)機的潤滑系統中被(bei)廣(guang)泛采用(yong)。油泵在運轉中(zhong)的故障通常是(shi)潤滑(hua)系統(tong)中油(you)壓降低(di),甚(shen)至有(you)時打(da)不上(shang)油。其原因大體有:1)旋(xuan)轉方向(xiang)與(yu)規定(ding)方向相反;2)吸油(you)管路不(bu)嚴(yan)密,單(dan)向閥卡住;3)油泵(beng)的泵體與(yu)泵蓋(gai)之間(jian)密封(feng)不良(liang);4)油槽(cao)内(nei)油(you)量不(bu)足;5)油(you)泵(beng)零件嚴(yan)重磨(mo)損(sun);6)吸(xi)油過(guo)濾網被(bei)堵塞。

實際(ji)工作中(zhong)應根(gen)據(ju)具體情(qing)況進行不(bu)同處(chu)理。在(zai)檢修中應(ying)特别注意(yi)吸油(you)管道(dao)的密封,以(yi)及齒(chi)輪(lun)油(you)泵泵(beng)體與(yu)泵蓋(gai)之間(jian)的密(mi)封。吸入端如果(guo)密封不良(liang),則油(you)泵進口漏(lou),造成(cheng)油泵(beng)抽空(kong),自然(ran)就(jiu)要(yao)打不(bu)上油(you)。
