變量液壓泵與高壓泵常(chang)用種(zhong)類是液壓泵(beng)中根(gen)據能量和與(yu)壓力強度的不同而分的種(zhong)類，那么關(guan)于這兩種(zhong)泵(beng)之間有(you)什么區(qu)別(bie)呢？小編總結了兩者的特點，從中可以分析出兩者之間的差異。
高壓(ya)(ya)泵(beng)：為提(ti)高各類液壓(ya)(ya)泵(beng)的額定(ding)壓(ya)(ya)力(li)，除采取(qu)措施減(jian)小(xiao)泄漏、提(ti)高容(rong)積(ji)效(xiao)率外(wai)，還需要在(zai)(zai)結構設計(ji)時(shi)采取(qu)措施，減(jian)少作(zuo)(zuo)用在(zai)(zai)某些零件上的不平(ping)衡力(li)。如(ru)：在(zai)(zai)軸向柱(zhu)塞(sai)泵(beng)中，將滑履與(yu)斜盤(pan)、缸體與(yu)配流盤(pan)之間(jian)設置靜壓(ya)(ya)平(ping)衡措施；在(zai)(zai)雙作(zuo)(zuo)用葉片(pian)(pian)泵(beng)中，采用子母葉片(pian)(pian)、雙葉片(pian)(pian)、柱(zhu)銷(xiao)葉片(pian)(pian)等措施，減(jian)小(xiao)吸油區(qu)葉片(pian)(pian)根(gen)部(bu)的液壓(ya)(ya)作(zuo)(zuo)用力(li)，以減(jian)小(xiao)葉片(pian)(pian)頂部(bu)對定(ding)子吸油區(qu)段造成的磨損(sun)。
對于齒輪泵除(chu)在泵的(de)端面間隙設置自動浮動補償機構外，還采(cai)用了開徑向(xiang)力(li)(li)平衡槽等措施(shi)，補償作用在齒輪軸上(shang)的(de)液壓徑向(xiang)不平衡力(li)(li)。
變量液壓泵
排(pai)(pai)量(liang)(liang)(liang)(liang)(liang)(liang)可以(yi)改變(bian)(bian)(bian)(bian)(bian)(bian)(bian)的液(ye)壓泵(beng)(beng)(beng)稱為變(bian)(bian)(bian)(bian)(bian)(bian)(bian)量(liang)(liang)(liang)(liang)(liang)(liang)泵(beng)(beng)(beng)， 按照變(bian)(bian)(bian)(bian)(bian)(bian)(bian)量(liang)(liang)(liang)(liang)(liang)(liang)方(fang)式不同有(you)手動(dong)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)量(liang)(liang)(liang)(liang)(liang)(liang)泵(beng)(beng)(beng)(含手動(dong)伺服變(bian)(bian)(bian)(bian)(bian)(bian)(bian)量(liang)(liang)(liang)(liang)(liang)(liang))和自動(dong)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)量(liang)(liang)(liang)(liang)(liang)(liang)泵(beng)(beng)(beng)兩種，自動(dong)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)量(liang)(liang)(liang)(liang)(liang)(liang)泵(beng)(beng)(beng)又(you)分恒(heng)(heng)(heng)壓變(bian)(bian)(bian)(bian)(bian)(bian)(bian)量(liang)(liang)(liang)(liang)(liang)(liang)泵(beng)(beng)(beng)、恒(heng)(heng)(heng)流量(liang)(liang)(liang)(liang)(liang)(liang)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)量(liang)(liang)(liang)(liang)(liang)(liang)泵(beng)(beng)(beng)、恒(heng)(heng)(heng)功率(lv)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)量(liang)(liang)(liang)(liang)(liang)(liang)泵(beng)(beng)(beng)、限壓式變(bian)(bian)(bian)(bian)(bian)(bian)(bian)量(liang)(liang)(liang)(liang)(liang)(liang)泵(beng)(beng)(beng)、差(cha)壓式變(bian)(bian)(bian)(bian)(bian)(bian)(bian)量(liang)(liang)(liang)(liang)(liang)(liang)泵(beng)(beng)(beng)等。軸向柱塞泵(beng)(beng)(beng)通(tong)過變(bian)(bian)(bian)(bian)(bian)(bian)(bian)量(liang)(liang)(liang)(liang)(liang)(liang)機構改變(bian)(bian)(bian)(bian)(bian)(bian)(bian)斜盤傾角可以(yi)改變(bian)(bian)(bian)(bian)(bian)(bian)(bian)排(pai)(pai)量(liang)(liang)(liang)(liang)(liang)(liang)；徑向柱塞泵(beng)(beng)(beng)和單作(zuo)用葉片泵(beng)(beng)(beng)是(shi)通(tong)過改變(bian)(bian)(bian)(bian)(bian)(bian)(bian)定子(zi)相對轉子(zi)軸線的偏心距(ju)改變(bian)(bian)(bian)(bian)(bian)(bian)(bian)排(pai)(pai)量(liang)(liang)(liang)(liang)(liang)(liang)。
限壓式(shi)變(bian)(bian)量(liang)葉(xie)片泵的(de)原理是自動變(bian)(bian)量(liang)的(de)變(bian)(bian)量(liang)泵工作(zuo)(zuo)(zuo)過程的(de)典(dian)型范例。其工作(zuo)(zuo)(zuo)過程主要(yao)是分析(xi)作(zuo)(zuo)(zuo)用在(zai)定子兩端的(de)液(ye)壓力與(yu)彈簧力相互作(zuo)(zuo)(zuo)用而(er)使定子與(yu)轉子間偏心(xin)得到自動調整(zheng)的(de)過程，最后達到泵的(de)輸出(chu)流量(liang)隨泵出(chu)口壓力的(de)增加而(er)自動變(bian)(bian)小(xiao)的(de)效果。
可以通過調(diao)整(zheng)(zheng)彈簧調(diao)整(zheng)(zheng)螺釘(ding)和最大偏心螺釘(ding)來調(diao)整(zheng)(zheng)泵的(de)限定壓力和最大流(liu)量(liang)；也可以通過調(diao)整(zheng)(zheng)上述螺釘(ding)，分析泵的(de)特性曲線(xian)的(de)變化過程。
