數控母排加工機上的(de)(de)液(ye)壓泵(beng)(beng)是加工機本(ben)身最重要的(de)(de)組成(cheng)部分(fen)，液(ye)壓泵(beng)(beng)的(de)(de)日(ri)常(chang)保養(yang)也就非常(chang)的(de)(de)重要，直軸斜(xie)盤式柱塞泵(beng)(beng)分(fen)為壓力供(gong)油(you)型的(de)(de)自吸油(you)型兩種，下面小(xiao)編就為大家(jia)說一下關于數控母排加工機液(ye)壓泵(beng)(beng)的(de)(de)保養(yang)知識：

壓(ya)(ya)(ya)(ya)(ya)力供(gong)油(you)型(xing)(xing)(xing)(xing)液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)大(da)(da)都采用(yong)(yong)(yong)有(you)(you)氣壓(ya)(ya)(ya)(ya)(ya)的(de)(de)油(you)箱(xiang)，也有(you)(you)液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)本(ben)身(shen)帶有(you)(you)補(bu)油(you)分(fen)(fen)泵(beng)(beng)(beng)向液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)進油(you)口提供(gong)壓(ya)(ya)(ya)(ya)(ya)力油(you)的(de)(de)。自(zi)(zi)吸(xi)(xi)油(you)型(xing)(xing)(xing)(xing)液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)的(de)(de)自(zi)(zi)吸(xi)(xi)油(you)能力很強(qiang)，無需外力供(gong)油(you)。靠(kao)氣壓(ya)(ya)(ya)(ya)(ya)供(gong)油(you)的(de)(de)液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)箱(xiang)，在(zai)每次啟動機(ji)(ji)(ji)器(qi)后(hou)(hou)，必須等液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)漬(zi)箱(xiang)達到(dao)(dao)使(shi)用(yong)(yong)(yong)氣壓(ya)(ya)(ya)(ya)(ya)后(hou)(hou)，才能操作機(ji)(ji)(ji)械。如(ru)(ru)液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)油(you)箱(xiang)的(de)(de)氣壓(ya)(ya)(ya)(ya)(ya)不(bu)(bu)足時就擔任(ren)機(ji)(ji)(ji)器(qi)，會對(dui)液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)內(nei)的(de)(de)與(yu)滑(hua)鞭(bian)造(zao)成拉脫(tuo)現(xian)(xian)(xian)象，母(mu)(mu)排(pai)(pai)(pai)加(jia)工機(ji)(ji)(ji)出會造(zao)成泵(beng)(beng)(beng)體內(nei)回程板與(yu)壓(ya)(ya)(ya)(ya)(ya)板的(de)(de)非正常(chang)(chang)磨損。采用(yong)(yong)(yong)補(bu)油(you)泵(beng)(beng)(beng)供(gong)油(you)的(de)(de)柱(zhu)塞泵(beng)(beng)(beng)，使(shi)用(yong)(yong)(yong)3000h后(hou)(hou)，操作人員每日需對(dui)柱(zhu)塞泵(beng)(beng)(beng)檢查(cha)1-2次，檢查(cha)液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)運轉聲響是(shi)否正常(chang)(chang)。如(ru)(ru)發現(xian)(xian)(xian)液(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)缸速度(du)(du)下降或悶車時，就應(ying)(ying)(ying)(ying)該對(dui)補(bu)油(you)泵(beng)(beng)(beng)解體檢查(cha)，檢查(cha)葉輪邊(bian)沿是(shi)否有(you)(you)刮傷現(xian)(xian)(xian)象，內(nei)齒輪泵(beng)(beng)(beng)間隙是(shi)否過大(da)(da)。戶內(nei)開關(guan)設備和控(kong)制設備中(zhong)(zhong)，母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)按截(jie)面(mian)分(fen)(fen)為(wei)(wei)矩形(xing)、圓(yuan)(yuan)形(xing)、D型(xing)(xing)(xing)(xing)、U型(xing)(xing)(xing)(xing)等，其中(zhong)(zhong)由(you)于(yu)(yu)同截(jie)面(mian)的(de)(de)矩形(xing)母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)較圓(yuan)(yuan)形(xing)、D型(xing)(xing)(xing)(xing)、U型(xing)(xing)(xing)(xing)等母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)電(dian)(dian)(dian)阻小、散熱(re)(re)(re)面(mian)大(da)(da)、載流量高等原因，矩形(xing)母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)在(zai)40.5kV及以(yi)下電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)等級中(zhong)(zhong)應(ying)(ying)(ying)(ying)用(yong)(yong)(yong)最廣泛。圓(yuan)(yuan)形(xing)和D型(xing)(xing)(xing)(xing)母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)由(you)于(yu)(yu)集膚(fu)效應(ying)(ying)(ying)(ying)較好，防(fang)電(dian)(dian)(dian)暈效果好,也有(you)(you)應(ying)(ying)(ying)(ying)用(yong)(yong)(yong)，但連接(jie)比(bi)較復雜(za)。U型(xing)(xing)(xing)(xing)母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)一(yi)(yi)般用(yong)(yong)(yong)于(yu)(yu)電(dian)(dian)(dian)流較大(da)(da)、力效應(ying)(ying)(ying)(ying)要求高的(de)(de)設備中(zhong)(zhong)，如(ru)(ru)發電(dian)(dian)(dian)機(ji)(ji)(ji)出口開關(guan)柜。其額(e)定(ding)電(dian)(dian)(dian)流大(da)(da)，一(yi)(yi)般達到(dao)(dao)5000A以(yi)上(shang)，額(e)定(ding)峰值耐受電(dian)(dian)(dian)流(IP)大(da)(da)，一(yi)(yi)般為(wei)(wei)50kA以(yi)上(shang)。按材質(zhi)分(fen)(fen)，可(ke)分(fen)(fen)為(wei)(wei)銅(tong)母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)、鋁母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)、鐵母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)，其中(zhong)(zhong)銅(tong)母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)由(you)于(yu)(yu)載流量大(da)(da)，四合一(yi)(yi)母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)加(jia)工機(ji)(ji)(ji)抗腐蝕性能和力效應(ying)(ying)(ying)(ying)好，應(ying)(ying)(ying)(ying)用(yong)(yong)(yong)最廣泛。鋁質(zhi)母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)在(zai)電(dian)(dian)(dian)流小、非沿海(hai)和非石化(hua)系(xi)統(tong)也有(you)(you)應(ying)(ying)(ying)(ying)用(yong)(yong)(yong)。使(shi)用(yong)(yong)(yong)鐵母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)主(zhu)要從經濟上(shang)考(kao)慮(lv)，主(zhu)要應(ying)(ying)(ying)(ying)用(yong)(yong)(yong)于(yu)(yu)PT連接(jie)線(xian)(xian)(xian)(xian)(xian)(xian)。按自(zi)(zi)然狀(zhuang)態可(ke)分(fen)(fen)為(wei)(wei)硬母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)和軟母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)。軟母(mu)(mu)線(xian)(xian)(xian)(xian)(xian)(xian)主(zhu)要應(ying)(ying)(ying)(ying)用(yong)(yong)(yong)于(yu)(yu)連接(jie)不(bu)(bu)便(bian)可(ke)以(yi)吸(xi)(xi)收(shou)一(yi)(yi)些(xie)力效應(ying)(ying)(ying)(ying)的(de)(de)場所，如(ru)(ru)斷(duan)路器(qi)內(nei)部。熱(re)(re)(re)縮(suo)管(guan)在(zai)加(jia)熱(re)(re)(re)收(shou)縮(suo)過程中(zhong)(zhong)，由(you)于(yu)(yu)銅(tong)的(de)(de)導熱(re)(re)(re)性能非常(chang)(chang)好，會讓(rang)(rang)貼(tie)緊(jin)銅(tong)排(pai)(pai)(pai)部分(fen)(fen)的(de)(de)熱(re)(re)(re)縮(suo)管(guan)溫度(du)(du)立即降低，而緊(jin)貼(tie)銅(tong)排(pai)(pai)(pai)，這種(zhong)現(xian)(xian)(xian)象稱(cheng)之為(wei)(wei)“貼(tie)冷”。為(wei)(wei)防(fang)止貼(tie)冷現(xian)(xian)(xian)象的(de)(de)發生，加(jia)熱(re)(re)(re)套管(guan)前，應(ying)(ying)(ying)(ying)先對(dui)銅(tong)排(pai)(pai)(pai)預(yu)加(jia)熱(re)(re)(re)，讓(rang)(rang)銅(tong)排(pai)(pai)(pai)溫度(du)(du)略高于(yu)(yu)環境溫度(du)(du)，然后(hou)(hou)套上(shang)銅(tong)排(pai)(pai)(pai)收(shou)縮(suo)，這樣可(ke)以(yi)減少或者避免貼(tie)冷現(xian)(xian)(xian)象。
