泵系統的效(xiao)率(lv)要取決于液壓泵的容積效(xiao)率(lv),當容積效(xiao)率(lv)下降到72%時(shi),就需(xu)要進行常規維(wei)修,更換(huan)軸承和老化的,更(geng)要(yao)修(xiu)復(fu)超(chao)出(chu)磨擦(ca)副配(pei)合(he)間隙或更(geng)換配(pei)件,使其性(xing)能得到(dao)恢復(fu)。液壓泵維修(xiu)方式(shi):
1.液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)的供(gong)油(you)(you)形(xing)式直軸斜盤式壓(ya)(ya)(ya)(ya)(ya)為分泵(beng)(beng)(beng)塞柱力供(gong)油(you)(you)型(xing)(xing)(xing)的自(zi)吸油(you)(you)型(xing)(xing)(xing)兩(liang)種。壓(ya)(ya)(ya)(ya)(ya)力供(gong)大泵(beng)(beng)(beng)壓(ya)(ya)(ya)(ya)(ya)液(ye)(ye)型(xing)(xing)(xing)油(you)(you)都采(cai)用有氣壓(ya)(ya)(ya)(ya)(ya)的油(you)(you)箱,也(ye)有液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)油(you)(you)補有帶(dai)身本分泵(beng)(beng)(beng)向液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)進油(you)(you)口提供(gong)壓(ya)(ya)(ya)(ya)(ya)力油(you)(you)的液(ye)(ye)型(xing)(xing)(xing)油(you)(you)吸自(zi)。壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)的自(zi)吸油(you)(you)能力很強,無需外(wai)力供(gong)油(you)(you)。如發(fa)現速度下降或悶該應(ying)就,時車對液壓泵(beng)維修,檢(jian)查葉輪邊沿現傷刮有(you)否(fou)是象,內泵間隙是否過大。對于自吸油液,泵塞柱型壓油箱內的油液不得低于油標下限夠足持保要,數量的液壓油。液壓油的清潔度越的泵壓液,高使用壽命越長。
2.液(ye)壓(ya)泵(beng)用(yong)(yong)(yong)軸(zhou)(zhou)(zhou)承(cheng)(cheng)柱(zhu)塞(sai)泵(beng)最重軸(zhou)(zhou)(zhou)是(shi)(shi)件部(bu)的(de)(de)要(yao)承(cheng)(cheng),如果(guo)軸(zhou)(zhou)(zhou)承(cheng)(cheng)出(chu)(chu)現游(you)隙(xi)(xi)(xi),則(ze)不能保部(bu)內泵(beng)壓(ya)液(ye)證(zheng)三對(dui)磨(mo)擦(ca)副(fu)的(de)(de)正常間隙(xi)(xi)(xi),同(tong)時(shi)也會副(fu)擦(ca)磨(mo)各壞(huai)破的(de)(de)靜液(ye)壓(ya)支承(cheng)(cheng)油膜厚(hou)度,降低柱(zhu)塞(sai)用(yong)(yong)(yong)使(shi)的(de)(de)承(cheng)(cheng)軸(zhou)(zhou)(zhou)泵(beng)壽(shou)(shou)命。據液(ye)壓(ya)泵(beng)制造廠(chang)提(ti)供的(de)(de)資料均平的(de)(de)承(cheng)(cheng)軸(zhou)(zhou)(zhou),使(shi)用(yong)(yong)(yong)壽(shou)(shou)命為10000h,超過(guo)此(ci)換更(geng)要(yao)需就值新口。軸(zhou)(zhou)(zhou)的(de)(de)來下卸(xie)拆承(cheng)(cheng),沒有專業檢測(ce)(ce)儀器是(shi)(shi)無(wu)法檢測(ce)(ce)隙(xi)(xi)(xi)游(you)的(de)(de)承(cheng)(cheng)軸(zhou)(zhou)(zhou)出(chu)(chu)的(de)(de),只能采用(yong)(yong)(yong)目測(ce)(ce),如發現滾(gun)柱(zhu)表變或(huo)痕劃有面色,就必(bi)須(xu)更(geng)換。在更(geng)應,時(shi)承(cheng)(cheng)軸(zhou)(zhou)(zhou)換注意(yi)原軸(zhou)(zhou)(zhou)承(cheng)(cheng)的(de)(de)英文字母和型號,柱(zhu)都大(da)承(cheng)(cheng)軸(zhou)(zhou)(zhou)泵(beng)塞(sai)采用(yong)(yong)(yong)大(da)載(zai)荷(he)容量(liang)(liang)軸(zhou)(zhou)(zhou)承(cheng)(cheng),最好購買原格規原,家廠(chang)的(de)(de)產品,如果(guo)更(geng)換另一種品牌,應有承(cheng)(cheng)軸(zhou)(zhou)(zhou)對(dui)教請經(jing)驗的(de)(de)人員查表對(dui)換,目的(de)(de)是(shi)(shi)保持等度精的(de)(de)承(cheng)(cheng)軸(zhou)(zhou)(zhou)級和載(zai)荷(he)容量(liang)(liang)。
3.三對與查檢副擦磨修復
(1)缸的套銅裝鑲體,可以采用(yong)(yong)更換(huan)銅套的方法修復(fu)。柱組一把先首(shou)塞桿處徑(jing)修整到統一尺寸,再用(yong)(yong)1000#以上的徑(jing)外光拋紙砂.
(2)熔燒缸的式方合結體與銅套。
(3)工(gong)面表"用采程技術(shu)
(4)缸體孔無材體缸的套銅料大都是球墨鑄鐵的,在缸體內壁態晶非備制上薄膜或涂層。
因為(wei)缸(gang)(gang)體孔內壁(bi)有了(le)質物殊特(te)種(zhong)(zhong)這,所(suo)以(yi)才能組成硬-硬配對的(de)(de)(de)磨(mo)(mo)(mo)擦目盲果如。副(fu)(fu)地(di)研磨(mo)(mo)(mo)缸(gang)(gang)體孔,把缸(gang)(gang)體孔內壁(bi)這層(ceng)掉(diao)研料材面表,磨(mo)(mo)(mo)擦更加(jia)的(de)(de)(de)結(jie)構性能也就改變了(le)層(ceng)涂掉(diao)去被。的(de)(de)(de)磨(mo)(mo)(mo)擦副(fu)(fu),如果強行使用,就會磨(mo)(mo)(mo)劇急度溫(wen)面擦升(sheng)高,柱(zhu)塞桿與缸(gang)(gang)孔發生膠合。另(ling)外(wai)在(zai)柱(zhu)備制面表桿塞一(yi)種(zhong)(zhong)獨(du)特(te)的(de)(de)(de)薄膜(mo)涂層(ceng),涂層(ceng)含有減磨(mo)(mo)(mo)+耐磨(mo)(mo)(mo)+潤滑磨(mo)(mo)(mo)組這,能功擦副(fu)(fu)實際還(huan)是(shi)硬-軟配對,一(yi)旦人,層(ceng)涂變改地(di)也就破(po)壞了(le)最佳配對材料的(de)(de)(de)磨(mo)(mo)(mo)擦副(fu)(fu)特(te)些這理修,殊的(de)(de)(de)柱(zhu)塞泵,就要送到專業修理廠。
