工(gong)作域和如何(he)使用

是將手(shou)動機械(xie)能轉(zhuan)換為(wei)液壓能的(de)(de)一種(zhong)小型(xing)液壓泵(beng) 站。在使(shi)用(yong)(yong)配(pei)套油(you)缸及專(zhuan)用(yong)(yong)工(gong)(gong)(gong)具的(de)(de)情況下，可(ke)(ke)進行各種(zhong)作業，如起重、彎形(xing)、校直、剪切、鉚合、裝配(pei)、拆卸(xie)及一些建筑施工(gong)(gong)(gong)、軍事施工(gong)(gong)(gong)等。油(you)泵(beng)的(de)(de)主(zhu)要特(te)點是：高壓、手(shou)動、超小型(xing)，攜(xie)帶方(fang)便(bian)，操作簡單(dan)，應用(yong)(yong)范圍廣。　雙(shuang)向(xiang)手(shou)動泵(beng)是通過柱塞(sai)的(de)(de)作用(yong)(yong)將機械(xie)油(you)或液壓油(you)轉(zhuan)換成壓力油(you)，變(bian)成一種(zhong)特(te)殊的(de)(de)動力源。具有工(gong)(gong)(gong)效顯著、性能穩定、安全可(ke)(ke)靠、攜(xie)帶方(fang)便(bian)等明顯特(te)點，主(zhu)要技術指(zhi)標達(da)到國外同類產(chan)品水平.

工(gong)作(zuo)原理可分四個過(guo)程：　 1、充(chong)液：油(you)(you)(you)(you)(you)(you)泵在(zai)開始工(gong)作(zuo)時，油(you)(you)(you)(you)(you)(you)液被高(gao)(gao)(gao)(gao)低(di)壓(ya)(ya)(ya)(ya)(ya)(ya)柱(zhu)塞(sai)同時壓(ya)(ya)(ya)(ya)(ya)(ya)入高(gao)(gao)(gao)(gao)低(di)壓(ya)(ya)(ya)(ya)(ya)(ya)單向閥(fa)(fa)(fa)，通過(guo)高(gao)(gao)(gao)(gao)低(di)壓(ya)(ya)(ya)(ya)(ya)(ya)單向閥(fa)(fa)(fa)進入油(you)(you)(you)(you)(you)(you)缸。當壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)升(sheng)至lMpa時，則(ze)(ze)低(di)壓(ya)(ya)(ya)(ya)(ya)(ya)油(you)(you)(you)(you)(you)(you)從(cong)低(di)壓(ya)(ya)(ya)(ya)(ya)(ya)溢流閥(fa)(fa)(fa)溢回(hui)儲(chu)油(you)(you)(you)(you)(you)(you)管。　　 2、升(sheng)壓(ya)(ya)(ya)(ya)(ya)(ya)：在(zai)上(shang)述過(guo)程的(de)基礎上(shang)。高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)柱(zhu)塞(sai)繼(ji)續工(gong)作(zuo)，壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)逐漸升(sheng)高(gao)(gao)(gao)(gao)。當壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)超(chao)過(guo)額定壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)63Mpa時，則(ze)(ze)高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)打(da)開，高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)油(you)(you)(you)(you)(you)(you)從(cong)高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)溢回(hui)儲(chu)油(you)(you)(you)(you)(you)(you)管，壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)始終(zhong)保持在(zai)63Mpa。高(gao)(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)就是(shi)安全閥(fa)(fa)(fa)。　 3、工(gong)作(zuo)；在(zai)工(gong)作(zuo)過(guo)程中，由于工(gong)作(zuo)缸做功．壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)會(hui)減(jian)小(xiao)，所以(yi)要隨時搖(yao)動(dong)手柄，保持所需(xu)的(de)工(gong)作(zuo)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)，直(zhi)至工(gong)作(zuo)結束。　 4、卸載(zai)(zai)：油(you)(you)(you)(you)(you)(you)泵工(gong)作(zuo)完(wan)(wan)畢，需(xu)要將(jiang)壓(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)減(jian)至零(ling)。打(da)開卸載(zai)(zai)閥(fa)(fa)(fa)，油(you)(you)(you)(you)(you)(you)液流回(hui)儲(chu)油(you)(you)(you)(you)(you)(you)管，完(wan)(wan)成(cheng)卸載(zai)(zai)工(gong)作(zuo)。　 充(chong)油(you)(you)(you)(you)(you)(you)、升(sheng)壓(ya)(ya)(ya)(ya)(ya)(ya)、工(gong)作(zuo)過(guo)程實際上(shang)是(shi)不可分割的(de)。只要動(dong)手柄就可以(yi)完(wan)(wan)成(cheng)這三個過(guo)程,

那(nei)么手(shou)動(dong)(dong)(dong)油(you)(you)泵(beng)(beng)(beng)(beng)(beng)是(shi)(shi)由哪幾部(bu)(bu)分(fen)(fen)(fen)(fen)組(zu)成：1、泵(beng)(beng)(beng)(beng)(beng)體(ti)部(bu)(bu)分(fen)(fen)(fen)(fen)；2、手(shou)柄(bing)部(bu)(bu)分(fen)(fen)(fen)(fen)；3、儲(chu)油(you)(you)箱(xiang)；4、后座(zuo)部(bu)(bu)分(fen)(fen)(fen)(fen)　　 A、泵(beng)(beng)(beng)(beng)(beng)體(ti)部(bu)(bu)分(fen)(fen)(fen)(fen)：泵(beng)(beng)(beng)(beng)(beng)體(ti)部(bu)(bu)分(fen)(fen)(fen)(fen)是(shi)(shi)油(you)(you)泵(beng)(beng)(beng)(beng)(beng)的(de)(de)主要(yao)部(bu)(bu)分(fen)(fen)(fen)(fen)，高壓(ya)工(gong)作(zuo)(zuo)(zuo)腔(qiang)(qiang)、低壓(ya)工(gong)作(zuo)(zuo)(zuo)腔(qiang)(qiang)、兩(liang)(liang)(liang)個(ge)單向(xiang)閥(fa)(fa)(fa)、高壓(ya)閥(fa)(fa)(fa)（安全(quan)閥(fa)(fa)(fa)）、低壓(ya)閥(fa)(fa)(fa)、卸載(zai)閥(fa)(fa)(fa)、兩(liang)(liang)(liang)個(ge)止(zhi)回閥(fa)(fa)(fa)、進(jin)油(you)(you)口等都在上面。各處(chu)孔有機聯系在一(yi)起。B、兩(liang)(liang)(liang)個(ge)單向(xiang)閥(fa)(fa)(fa)是(shi)(shi)防止(zhi)壓(ya)力(li)(li)油(you)(you)回流(liu)(liu)。兩(liang)(liang)(liang)個(ge)單向(xiang)閥(fa)(fa)(fa)其(qi)規格(ge)、作(zuo)(zuo)(zuo)用是(shi)(shi)一(yi)樣(yang)的(de)(de)。低壓(ya)閥(fa)(fa)(fa)和高壓(ya)閥(fa)(fa)(fa)的(de)(de)作(zuo)(zuo)(zuo)用是(shi)(shi)壓(ya)力(li)(li)控(kong)制。分(fen)(fen)(fen)(fen)別將壓(ya)力(li)(li)控(kong)制在1.5MPa和63MPa。進(jin)油(you)(you)口處(chu)的(de)(de)兩(liang)(liang)(liang)個(ge)鋼球(qiu)是(shi)(shi)止(zhi)回閥(fa)(fa)(fa)。工(gong)作(zuo)(zuo)(zuo)完畢后松(song)動(dong)(dong)(dong)卸載(zai)閥(fa)(fa)(fa)、壓(ya)力(li)(li)油(you)(you)流(liu)(liu)回儲(chu)油(you)(you)管，完成卸載(zai)工(gong)作(zuo)(zuo)(zuo)。 C、手(shou)柄(bing)部(bu)(bu)分(fen)(fen)(fen)(fen)：主要(yao)由壓(ya)桿(gan)、壓(ya)把組(zu)成。靠兩(liang)(liang)(liang)個(ge)銷子與泵(beng)(beng)(beng)(beng)(beng)體(ti)和柱塞(sai)連接。手(shou)動(dong)(dong)(dong)力(li)(li)作(zuo)(zuo)(zuo)用在壓(ya)桿(gan)上，帶動(dong)(dong)(dong)柱塞(sai)作(zuo)(zuo)(zuo)往復(fu)運(yun)動(dong)(dong)(dong)，產生(sheng)油(you)(you)液的(de)(de)壓(ya)力(li)(li)。D、在后座(zuo)或(huo)油(you)(you)箱(xiang)上面裝有注油(you)(you)、放氣孔。松(song)開螺絲就(jiu)可進(jin)行放氣和進(jin)氣。
