?液壓泵是以液體為動力的機械設(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，則泵內(nèi)壓力就低 1、減少油液流量的變化。
油液在流動過程中，由于各種原因，會發(fā)生瞬時流量增大和急劇下降，當(dāng)達到一定流量時，由于壓力降低而開始下降，但當(dāng)達到一定溫度時又開始上升油液流動的速度、溫度、壓力三者之間的關(guān)系如圖所示配流盤可以使油液減少流量波動。
配流盤能夠提高油液的輸送效率以保證系統(tǒng)壓力波動不超過1pa 2、減少對設(shè)備的磨損 配流盤的流道是一種非凸凸的設(shè)計，可以減少流道間的摩擦力由于流體處于流動狀態(tài)，因而減少了機械設(shè)備對流道的磨損，從而降低了機械磨損。
另外，配流盤的形狀也可減輕泵對磨損，延長其使用壽命 3、減小輸送過程中的阻力 流體的運動是不可逆的，而且流體的運動是一個復(fù)雜的數(shù)學(xué)問題流體的運動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動是連續(xù)的，這就要求流體必須在指定的速度內(nèi)流動。
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，在配流盤的結(jié)構(gòu)上一般是用來減小壓力和流量之比這就要求配流盤能夠承受的壓力是最小的。
所以在用泵時應(yīng)盡可能地使配流盤承受的壓力盡可能大一般用直徑為60~150mm的圓盤體做配流盤這樣的配流盤稱為圓盤體 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控制的這些液壓泵的流道和閥桿位置不同，流道比較長，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
