?液壓泵是以液體為動(dòng)力的機(jī)械設(shè)備，它的輸出直接受到液壓系統(tǒng)的壓力和流量的控制壓力高流量大，流量就大，但是如果壓力低流量就小，壓力高流量小，壓力低流量就大如果壓力低流量大時(shí)，則泵內(nèi)壓力就低 1、減少油液流量的變化。
油液在流動(dòng)過(guò)程中，由于各種原因，會(huì)發(fā)生瞬時(shí)流量增大和急劇下降，當(dāng)達(dá)到一定流量時(shí)，由于壓力降低而開(kāi)始下降，但當(dāng)達(dá)到一定溫度時(shí)又開(kāi)始上升油液流動(dòng)的速度、溫度、壓力三者之間的關(guān)系如圖所示配流盤(pán)可以使油液減少流量波動(dòng)。
配流盤(pán)能夠提高油液的輸送效率以保證系統(tǒng)壓力波動(dòng)不超過(guò)1pa 2、減少對(duì)設(shè)備的磨損 配流盤(pán)的流道是一種非凸凸的設(shè)計(jì)，可以減少流道間的摩擦力由于流體處于流動(dòng)狀態(tài)，因而減少了機(jī)械設(shè)備對(duì)流道的磨損，從而降低了機(jī)械磨損。
另外，配流盤(pán)的形狀也可減輕泵對(duì)磨損，延長(zhǎng)其使用壽命 3、減小輸送過(guò)程中的阻力 流體的運(yùn)動(dòng)是不可逆的，而且流體的運(yùn)動(dòng)是一個(gè)復(fù)雜的數(shù)學(xué)問(wèn)題流體的運(yùn)動(dòng)在很大程度上取決于流體的流速和流體中的固體顆粒大小流體的運(yùn)動(dòng)是連續(xù)的，這就要求流體必須在指定的速度內(nèi)流動(dòng)。
液體表面和流體內(nèi)是有一定粗糙度的，表面粗糙度越大流體阻力越小流體表面粗糙度越小，其流動(dòng)就越快 4、使流量與壓力之比減小到最小 為減小流量與壓力之比，在配流盤(pán)的結(jié)構(gòu)上一般是用來(lái)減小壓力和流量之比這就要求配流盤(pán)能夠承受的壓力是最小的。
所以在用泵時(shí)應(yīng)盡可能地使配流盤(pán)承受的壓力盡可能大一般用直徑為60~150mm的圓盤(pán)體做配流盤(pán)這樣的配流盤(pán)稱為圓盤(pán)體 5、便于配流系統(tǒng) 液壓泵有很多種，有些是采用變速控制的，還有一些是用變速來(lái)控制的這些液壓泵的流道和閥桿位置不同，流道比較長(zhǎng)，閥桿位置較低，這種結(jié)構(gòu)可以方便配流。
另外，液控式液壓泵的閥桿為直線型，而且多采用變速閥，這樣配流系統(tǒng)就很容易了但這些流道與閥桿不同的是不能為高壓流量配流 90-L-100-KN-1-BC-60-P-3-F1-E-03-GBA-35-35-20 90L100KN1BC60P3F1E03GBA353520 90-L-100-KN-1-BC-60-P-3-F1-E-03-GBA-35-35-24
