威格士柱塞泵工作流程： 威格士柱(zhu)塞泵(beng)柱(zhu)塞往復(fu)運(yun)動總行(xing)程(cheng)(cheng)(cheng)L是不變(bian)的(de)(de)，由凸(tu)輪的(de)(de)升程(cheng)(cheng)(cheng)決(jue)定。柱(zhu)塞每循環(huan)的(de)(de)供(gong)(gong)油(you)量(liang)大小取決(jue)于(yu)供(gong)(gong)油(you)行(xing)程(cheng)(cheng)(cheng),供(gong)(gong)油(you)行(xing)程(cheng)(cheng)(cheng)不受凸(tu)輪軸控(kong)制是可變(bian)的(de)(de)。供(gong)(gong)油(you)開(kai)始時刻不隨(sui)供(gong)(gong)油(you)行(xing)程(cheng)(cheng)(cheng)的(de)(de)變(bian)化(hua)而(er)(er)變(bian)化(hua)。轉動柱(zhu)塞可改變(bian)供(gong)(gong)油(you)終(zhong)了時刻，從而(er)(er)改變(bian)供(gong)(gong)油(you)量(liang)。柱(zhu)塞泵(beng)工作(zuo)時，在噴油(you)泵(beng)凸(tu)輪軸上(shang)的(de)(de)凸(tu)輪與柱(zhu)塞彈(dan)簧的(de)(de)作(zuo)用下(xia)，迫使柱(zhu)塞作(zuo)上(shang)、下(xia)往復(fu)運(yun)動，從而(er)(er)完(wan)成泵(beng)油(you)任務，泵(beng)油(you)過程(cheng)(cheng)(cheng)可分(fen)為以下(xia)三個階段(duan)。 進油過程 當凸輪的凸起部(bu)分轉過去后(hou)，在(zai)彈簧力的作用下，柱(zhu)(zhu)塞(sai)(sai)向下運(yun)動，柱(zhu)(zhu)塞(sai)(sai)上(shang)(shang)部(bu)空間(jian)（稱為泵油(you)室）產(chan)生真空度(du)，當柱(zhu)(zhu)塞(sai)(sai)上(shang)(shang)端(duan)面把柱(zhu)(zhu)塞(sai)(sai)套上(shang)(shang)的進油(you)孔打開后(hou)，充(chong)滿在(zai)油(you)泵上(shang)(shang)體油(you)道內的柴油(you)經油(you)孔進入(ru)泵油(you)室，柱(zhu)(zhu)塞(sai)(sai)運(yun)動到下止點(dian)，進油(you)結束。 供油過程 當凸(tu)輪(lun)軸轉到(dao)凸(tu)輪(lun)的(de)凸(tu)起部(bu)(bu)分頂起滾輪(lun)體時，柱塞(sai)彈(dan)簧被壓(ya)縮，柱塞(sai)向上運動，燃油(you)(you)(you)受壓(ya)，一(yi)部(bu)(bu)分燃油(you)(you)(you)經油(you)(you)(you)孔(kong)流回噴油(you)(you)(you)泵上體油(you)(you)(you)腔(qiang)。當柱塞(sai)頂面遮住套筒上進油(you)(you)(you)孔(kong)的(de)上緣時，由于柱塞(sai)和套筒的(de)配合(he)間隙很小（0.0015-0.0025mm）使柱塞(sai)頂部(bu)(bu)的(de)泵油(you)(you)(you)室成為一(yi)個(ge)密封油(you)(you)(you)腔(qiang)，柱塞(sai)繼(ji)續上升，泵油(you)(you)(you)室內的(de)油(you)(you)(you)壓(ya)迅速升高，泵油(you)(you)(you)壓(ya)力>出油(you)(you)(you)閥(fa)彈(dan)簧力+高壓(ya)油(you)(you)(you)管剩(sheng)余壓(ya)力時，推開出油(you)(you)(you)閥(fa)，高壓(ya)柴(chai)油(you)(you)(you)經出油(you)(you)(you)閥(fa)進入(ru)高壓(ya)油(you)(you)(you)管，通過噴油(you)(you)(you)器噴入(ru)燃燒(shao)室。 回油過程 柱(zhu)塞向(xiang)(xiang)上(shang)供(gong)(gong)油(you)，當上(shang)行到(dao)柱(zhu)塞上(shang)的(de)(de)斜槽(cao)（停供(gong)(gong)邊）與套筒上(shang)的(de)(de)回油(you)孔相通(tong)時，泵油(you)室低壓(ya)油(you)路便與柱(zhu)塞頭(tou)部的(de)(de)中(zhong)孔和徑向(xiang)(xiang)孔及斜槽(cao)溝通(tong)，油(you)壓(ya)驟然下降，出(chu)油(you)閥在(zai)彈(dan)簧(huang)力的(de)(de)作(zuo)用下迅速關閉，停止(zhi)供(gong)(gong)油(you)。此后(hou)柱(zhu)塞還要上(shang)行，當凸輪的(de)(de)凸起部分(fen)轉過去后(hou)，在(zai)彈(dan)簧(huang)的(de)(de)作(zuo)用下，柱(zhu)塞又下行。此時便開始了(le)下一(yi)個循環。 柱塞泵以一個柱塞為原理介紹，一個柱塞泵上有兩個單向閥，并且方向相反，柱塞向一個方向運動時缸內出現負壓，這時一個單向閥打開液體被吸入缸內，柱塞向另一個方向運動時，將液體壓縮后另一個單向閥被打開，被吸入缸內的液體被排出。這種工作方式連續運動后就形成了連續供油 。
VICKERS柱塞泵的機械分類： ①軸向柱塞泵 軸(zhou)向柱塞(sai)(sai)(sai)泵(beng)(beng)(beng)是(shi)(shi)活塞(sai)(sai)(sai)或(huo)柱塞(sai)(sai)(sai)的(de)往(wang)復(fu)運(yun)動(dong)方(fang)向與(yu)(yu)缸體中(zhong)心軸(zhou)平行的(de)柱塞(sai)(sai)(sai)泵(beng)(beng)(beng)。軸(zhou)向柱塞(sai)(sai)(sai)泵(beng)(beng)(beng)是(shi)(shi)利用與(yu)(yu)傳動(dong)軸(zhou)平行的(de)柱塞(sai)(sai)(sai)在柱塞(sai)(sai)(sai)孔內往(wang)復(fu)運(yun)動(dong)所產生的(de)容(rong)積變化來進行工作(zuo)的(de)。由于柱塞(sai)(sai)(sai)和柱塞(sai)(sai)(sai)孔都是(shi)(shi)圓形零件(jian)，加(jia)工時可以(yi)達到(dao)很高的(de)精度(du)配合，因此容(rong)積效率高，運(yun)轉平穩，流量均勻性(xing)好，噪聲(sheng)低，工作(zuo)壓(ya)力(li)高等優點，但(dan)對液壓(ya)油的(de)污(wu)染(ran)較敏(min)感，結構較復(fu)雜，造價較高。 ②直軸斜盤式柱塞泵 直軸(zhou)斜(xie)盤式柱(zhu)塞泵(beng)(beng)分為(wei)壓(ya)(ya)(ya)(ya)(ya)力(li)(li)供(gong)油(you)(you)(you)(you)型(xing)的(de)(de)(de)自吸油(you)(you)(you)(you)型(xing)兩(liang)種。壓(ya)(ya)(ya)(ya)(ya)力(li)(li)供(gong)油(you)(you)(you)(you)型(xing)液壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)大(da)都采用有(you)氣(qi)壓(ya)(ya)(ya)(ya)(ya)的(de)(de)(de)油(you)(you)(you)(you)箱(xiang)，也有(you)液壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)本(ben)身帶有(you)補(bu)油(you)(you)(you)(you)分泵(beng)(beng)向(xiang)液壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)進(jin)油(you)(you)(you)(you)口(kou)提供(gong)壓(ya)(ya)(ya)(ya)(ya)力(li)(li)油(you)(you)(you)(you)的(de)(de)(de)。自吸油(you)(you)(you)(you)型(xing)液壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)的(de)(de)(de)自吸油(you)(you)(you)(you)能力(li)(li)很強，無需外力(li)(li)供(gong)油(you)(you)(you)(you)。靠氣(qi)壓(ya)(ya)(ya)(ya)(ya)供(gong)油(you)(you)(you)(you)的(de)(de)(de)液壓(ya)(ya)(ya)(ya)(ya)油(you)(you)(you)(you)箱(xiang)，在每次啟動機器后(hou)(hou)，必須(xu)等液壓(ya)(ya)(ya)(ya)(ya)漬箱(xiang)達到使用氣(qi)壓(ya)(ya)(ya)(ya)(ya)后(hou)(hou)，才(cai)能操作機械(xie)。如液壓(ya)(ya)(ya)(ya)(ya)油(you)(you)(you)(you)箱(xiang)的(de)(de)(de)氣(qi)壓(ya)(ya)(ya)(ya)(ya)不足時就擔任機器，會對液壓(ya)(ya)(ya)(ya)(ya)泵(beng)(beng)內(nei)的(de)(de)(de)與滑(hua)鞭造成拉(la)脫(tuo)現象，出會造成泵(beng)(beng)體內(nei)回(hui)程板與壓(ya)(ya)(ya)(ya)(ya)板的(de)(de)(de)非(fei)正常磨損。 ③徑向柱塞泵 徑(jing)(jing)(jing)向(xiang)(xiang)柱(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)可分(fen)為(wei)閥(fa)配(pei)(pei)流(liu)與軸(zhou)(zhou)配(pei)(pei)流(liu)兩大(da)類。閥(fa)配(pei)(pei)流(liu)徑(jing)(jing)(jing)向(xiang)(xiang)柱(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)存在故障(zhang)率(lv)高、效率(lv)低等(deng)缺(que)點。上70、80年(nian)代(dai)發展的軸(zhou)(zhou)配(pei)(pei)流(liu)徑(jing)(jing)(jing)向(xiang)(xiang)柱(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)克服了閥(fa)配(pei)(pei)流(liu)徑(jing)(jing)(jing)向(xiang)(xiang)柱(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)的不足。由于(yu)徑(jing)(jing)(jing)向(xiang)(xiang)泵(beng)結(jie)構(gou)(gou)上的特點，陜定了軸(zhou)(zhou)配(pei)(pei)流(liu)徑(jing)(jing)(jing)向(xiang)(xiang)柱(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)比(bi)軸(zhou)(zhou)向(xiang)(xiang)柱(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)耐沖(chong)擊、壽命長、控(kong)制(zhi)精(jing)度高。變(bian)量(liang)行程短(duan)泵(beng)的變(bian)量(liang)是在變(bian)量(liang)柱(zhu)(zhu)塞(sai)(sai)(sai)和限位柱(zhu)(zhu)塞(sai)(sai)(sai)作用下(xia)，改變(bian)定子的偏心(xin)距(ju)實現的，而定于(yu)的zui大(da)偏心(xin)距(ju)為(wei)5—9mm(根據排(pai)量(liang)大(da)小不同)，變(bian)量(liang)行程很短(duan)。且變(bian)量(liang)機構(gou)(gou)設計為(wei)高壓操縱(zong)，由控(kong)制(zhi)閥(fa)進行控(kong)制(zhi)。故該泵(beng)的響(xiang)應速度快。徑(jing)(jing)(jing)向(xiang)(xiang)結(jie)構(gou)(gou)設計克服了如(ru)軸(zhou)(zhou)向(xiang)(xiang)柱(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)滑(hua)靴偏磨的問題。使其抗沖(chong)擊能力大(da)幅(fu)度提高。 ④液壓柱塞泵 液(ye)(ye)壓(ya)(ya)柱塞泵(beng)(beng)靠氣壓(ya)(ya)供油(you)(you)(you)(you)(you)的(de)(de)液(ye)(ye)壓(ya)(ya)油(you)(you)(you)(you)(you)箱(xiang)(xiang)，在每次啟動機器后(hou)，必須等液(ye)(ye)壓(ya)(ya)漬箱(xiang)(xiang)達到使(shi)用(yong)氣壓(ya)(ya)后(hou)，才能操(cao)作機械。直(zhi)軸斜盤式柱塞泵(beng)(beng)分為壓(ya)(ya)力(li)(li)(li)供油(you)(you)(you)(you)(you)型(xing)的(de)(de)自吸(xi)(xi)油(you)(you)(you)(you)(you)型(xing)兩(liang)種(zhong)。壓(ya)(ya)力(li)(li)(li)供油(you)(you)(you)(you)(you)型(xing)液(ye)(ye)壓(ya)(ya)泵(beng)(beng)大都采用(yong)有氣壓(ya)(ya)的(de)(de)油(you)(you)(you)(you)(you)箱(xiang)(xiang)，也有液(ye)(ye)壓(ya)(ya)泵(beng)(beng)本身帶(dai)有補油(you)(you)(you)(you)(you)分泵(beng)(beng)向液(ye)(ye)壓(ya)(ya)泵(beng)(beng)進油(you)(you)(you)(you)(you)口(kou)提供壓(ya)(ya)力(li)(li)(li)油(you)(you)(you)(you)(you)的(de)(de)。自吸(xi)(xi)油(you)(you)(you)(you)(you)型(xing)液(ye)(ye)壓(ya)(ya)泵(beng)(beng)的(de)(de)自吸(xi)(xi)油(you)(you)(you)(you)(you)能力(li)(li)(li)很強，無(wu)需外力(li)(li)(li)供油(you)(you)(you)(you)(you)。對(dui)于自吸(xi)(xi)油(you)(you)(you)(you)(you)型(xing)柱塞泵(beng)(beng)，液(ye)(ye)壓(ya)(ya)油(you)(you)(you)(you)(you)箱(xiang)(xiang)內(nei)的(de)(de)油(you)(you)(you)(you)(you)液(ye)(ye)不(bu)得(de)低于油(you)(you)(you)(you)(you)標下限，要保持(chi)足夠數量的(de)(de)液(ye)(ye)壓(ya)(ya)油(you)(you)(you)(you)(you)。液(ye)(ye)壓(ya)(ya)油(you)(you)(you)(you)(you)的(de)(de)清潔度越高，液(ye)(ye)壓(ya)(ya)泵(beng)(beng)的(de)(de)使(shi)用(yong)壽命越長。

【11】提升無泄漏系統設計(ji) 威格士VICKERS柱(zhu)塞泵過熱原因及(ji)解決 VICKERS由于多種因素的影響，系統經過長期運行后，總能量損失轉化成的熱量會比系統向外散發的熱量多，zui終導致系統過熱。具體表現形式如下。
①VICKERS液壓油的類型、黠度選擇不合理不同用途的液壓系統要求選用不同類 型的液壓油，而VICKERS液壓油的黠度受到溫度、壓力等諸多因素的影響。如果所選油液 黠度偏高，油液在流動過程中的摩擦阻力將增大，使功率損失增加，油溫升高; 相反，如果所選油液薪度偏低，隨著泄漏量的增加，油溫也會升高。
②威格士液壓系統所用調壓闊壓力調節不準確液壓系統常在液壓泵的出口處安 裝溢流間，用來調節系統壓力或起安全作用。如果該闊的調定壓力過高，將會使液壓泵在超過額定壓力的狀態下運行，即過載，不僅影響泵的使用性能，還會導致油溫升高。反之，如果起安全作用的溢流閥調定壓力過低，會使工作機構在正 常負載下頻繁出現溢流、卸荷，由于溢流伴隨著功率損失，也會引進油液發熱。
③VICKERS液壓油中混入空氣在液壓系統中通過節流閥來調節執行元件的運動速度。當液流流經節流口的喉部位置時，即使下游壓力較高，也會由于射流的收縮 和重新附壁，形成一個低壓區。當低壓區出現較高真空度時，油液將汽化，產生節流氣穴。
設阻尼孔進口(kou)容腔中的(de)壓力為(wei)(wei)Psa，下游(you)容腔的(de)壓力為(wei)(wei)ρda，收縮由此不難看出，當(dang)戶(hu)sa、ρda一定時，冉(ran)的(de)降低將使(shi)Cq增大，當(dang)ρc降至(zhi)油液 的(de)汽化壓時。 VICKERS柱塞泵(beng)柱塞往(wang)復運動(dong)總(zong)行程L是(shi)不變的(de)(de)，由凸(tu)輪(lun)的(de)(de)升程決定。柱塞每循(xun)環的(de)(de)供油(you)(you)(you)(you)量(liang)大小取決于(yu)供油(you)(you)(you)(you)行程,供油(you)(you)(you)(you)行程不受凸(tu)輪(lun)軸控制是(shi)可(ke)變的(de)(de)。供油(you)(you)(you)(you)開始時刻(ke)不隨供油(you)(you)(you)(you)行程的(de)(de)變化而(er)(er)變化。轉動(dong)柱塞可(ke)改變供油(you)(you)(you)(you)終了時刻(ke)，從(cong)而(er)(er)改變供油(you)(you)(you)(you)量(liang)。柱塞泵(beng)工作時，在噴油(you)(you)(you)(you)泵(beng)凸(tu)輪(lun)軸上(shang)的(de)(de)凸(tu)輪(lun)與(yu)柱塞彈簧的(de)(de)作用下(xia)，迫使柱塞作上(shang)、下(xia)往(wang)復運動(dong)，從(cong)而(er)(er)完成泵(beng)油(you)(you)(you)(you)任(ren)務。
