機械分類 柱(zhu)塞泵(beng)(beng)一(yi)般分(fen)為(wei)單(dan)柱(zhu)塞泵(beng)(beng)、臥式柱(zhu)塞泵(beng)(beng)、軸(zhou)向(xiang)柱(zhu)塞泵(beng)(beng)和徑向(xiang)柱(zhu)塞泵(beng)(beng)。 單柱塞泵 結構(gou)組成主要有(you)偏(pian)心輪(lun)、柱塞(sai)、彈簧、缸體(ti)、兩個(ge)單向閥(fa)。柱塞(sai)與缸體(ti)孔(kong)之間形(xing)成密閉容積。偏(pian)心輪(lun)旋轉(zhuan)一轉(zhuan),柱塞(sai)上下往復運動(dong)一次,向下運動(dong)吸油,向上運動(dong)排油。泵每轉(zhuan)一轉(zhuan)排出的油液體(ti)積稱為排量(liang),排量(liang)只與泵的結構(gou)參數有(you)關(guan)。 臥式柱塞泵 臥式(shi)柱(zhu)塞(sai)泵(beng)是由幾個柱(zhu)塞(sai)(一(yi)般為3個或6個)并(bing)列(lie)安裝,用(yong)(yong)1根曲(qu)軸通過連桿(gan)滑(hua)塊或由偏(pian)心軸直(zhi)接推動柱(zhu)塞(sai)做(zuo)往復(fu)運(yun)動,實現吸、排液(ye)體(ti)的(de)液(ye)壓泵(beng)。它們也都采(cai)用(yong)(yong)閥(fa)式(shi)配(pei)流裝置,而且大多為定量泵(beng)。煤(mei)礦液(ye)壓支架(jia)系統中的(de)乳化液(ye)泵(beng)一(yi)般都是臥式(shi)柱(zhu)塞(sai)泵(beng)。 乳(ru)化液(ye)泵用于采煤工作面,為液(ye)壓(ya)支架提(ti)供(gong)乳(ru)化液(ye),工作原理靠曲(qu)軸的旋轉帶動(dong)活塞(sai)做(zuo)往復運動(dong),實現吸液(ye)和排液(ye)。 軸向式 軸(zhou)向(xiang)柱(zhu)塞(sai)泵(英(ying)文名:Piston pump)是活塞(sai)或(huo)柱(zhu)塞(sai)的往(wang)復運(yun)動方(fang)向(xiang)與缸體中心軸(zhou)平行(xing)(xing)的柱(zhu)塞(sai)泵。軸(zhou)向(xiang)柱(zhu)塞(sai)泵利用與傳動軸(zhou)平行(xing)(xing)的柱(zhu)塞(sai)在柱(zhu)塞(sai)孔內往(wang)復運(yun)動所產生的容積變化來進行(xing)(xing)工(gong)作的。由(you)于柱(zhu)塞(sai)和(he)柱(zhu)塞(sai)孔都是圓形零件,加工(gong)時可(ke)以(yi)達(da)到很高的精度配合(he),因此容積效率高。 直軸斜盤式 直軸(zhou)斜(xie)盤式柱塞泵(beng)(beng)分為壓(ya)(ya)力(li)供(gong)油(you)(you)型和自吸油(you)(you)型兩種。壓(ya)(ya)力(li)供(gong)油(you)(you)型液壓(ya)(ya)泵(beng)(beng)大都是采用有氣(qi)壓(ya)(ya)的油(you)(you)箱(xiang),靠氣(qi)壓(ya)(ya)供(gong)油(you)(you)的液壓(ya)(ya)油(you)(you)箱(xiang),在每次啟(qi)動機器之后,必須等液壓(ya)(ya)漬箱(xiang)達(da)到使用氣(qi)壓(ya)(ya)后,才能操作機械(xie)。如(ru)液壓(ya)(ya)油(you)(you)箱(xiang)的氣(qi)壓(ya)(ya)不(bu)足(zu)時就啟(qi)動機器,會對液壓(ya)(ya)泵(beng)(beng)內的與滑靴造成(cheng)拉脫現象,出會造成(cheng)泵(beng)(beng)體內回程板與壓(ya)(ya)板的非(fei)正常磨損。 徑向式 徑(jing)向柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)可分(fen)為(wei)(wei)閥配流(liu)(liu)與(yu)軸(zhou)配流(liu)(liu)兩大類。閥配流(liu)(liu)徑(jing)向柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)存在(zai)故障率高(gao)、效率低等缺(que)點。上(shang)70、80年代發展的(de)軸(zhou)配流(liu)(liu)徑(jing)向柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)克服(fu)(fu)了閥配流(liu)(liu)徑(jing)向柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)的(de)不足。由于徑(jing)向泵(beng)(beng)結構(gou)上(shang)的(de)特點,固定了軸(zhou)配流(liu)(liu)徑(jing)向柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)比軸(zhou)向柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)耐(nai)沖擊(ji)、壽命長、控制精(jing)度高(gao)。變(bian)量(liang)行(xing)程短(duan)(duan)泵(beng)(beng)的(de)變(bian)量(liang)是在(zai)變(bian)量(liang)柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)和限位柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)作用下,改變(bian)定子的(de)偏心距實(shi)現的(de),而(er)定于的(de)zui大偏心距為(wei)(wei) 5—9mm(根據排量(liang)大小不同),變(bian)量(liang)行(xing)程很短(duan)(duan)。且變(bian)量(liang)機構(gou)設計為(wei)(wei)高(gao)壓操縱,由控制閥進(jin)行(xing)控制。故該泵(beng)(beng)的(de)響應速度快。徑(jing)向結構(gou)設計克服(fu)(fu)了如軸(zhou)向柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)滑(hua)靴偏磨的(de)問題。使其抗(kang)沖擊(ji)能力(li)大幅度提(ti)高(gao)。 液壓式 液(ye)壓(ya)(ya)柱(zhu)塞泵靠氣(qi)壓(ya)(ya)供油(you)(you)(you)(you)(you)的(de)液(ye)壓(ya)(ya)油(you)(you)(you)(you)(you)箱,在每次啟動機器后,必須等液(ye)壓(ya)(ya)油(you)(you)(you)(you)(you)箱達到使(shi)用(yong)氣(qi)壓(ya)(ya)后,才能(neng)操作機械。直軸斜(xie)盤式柱(zhu)塞泵分(fen)為壓(ya)(ya)力(li)供油(you)(you)(you)(you)(you)型的(de)自(zi)吸油(you)(you)(you)(you)(you)型兩種(zhong)。壓(ya)(ya)力(li)供油(you)(you)(you)(you)(you)型液(ye)壓(ya)(ya)泵大(da)都(dou)采用(yong)有氣(qi)壓(ya)(ya)的(de)油(you)(you)(you)(you)(you)箱,也有液(ye)壓(ya)(ya)泵本身帶(dai)有補油(you)(you)(you)(you)(you)分(fen)泵向液(ye)壓(ya)(ya)泵進(jin)油(you)(you)(you)(you)(you)口提供壓(ya)(ya)力(li)油(you)(you)(you)(you)(you)的(de)。自(zi)吸油(you)(you)(you)(you)(you)型液(ye)壓(ya)(ya)泵的(de)自(zi)吸油(you)(you)(you)(you)(you)能(neng)力(li)很強,無(wu)需外力(li)供油(you)(you)(you)(you)(you)。
