力士樂A4V,A10V,A11V系列柱塞泵，德國REXROTH軸向柱塞泵

力士樂變量軸向柱塞泵分類：按軸分類有:直軸，斜軸，通軸，不通軸  按配油形式有:平面配流，軸配流，閥配流其工作原理都是柱塞往復運動實現(xiàn)吸油和壓油動作。  通過配流零件保證吸油區(qū)與壓油區(qū)分隔開，不串通常用的有1，CY14-1B柱塞泵，其主要結(jié)構(gòu)特征是：不通軸，直軸，平面配流盤配流，斜盤變量結(jié)構(gòu)。              2，A6F斜軸泵（力士樂系列），其主要結(jié)構(gòu)特征是：斜軸，不通軸，平面配流，斜盤固定，缸體配流盤擺動變量。             3，A4V通軸泵（力士樂系列），其主要結(jié)構(gòu)特征是：通軸，直軸，平面配流盤配流，斜盤變量結(jié)構(gòu)，尾部可串接1-4臺合適的通軸泵?？杉梢簤合到y(tǒng)的*控制閥功能。            詳細結(jié)構(gòu)請參閱相關(guān)資料，網(wǎng)上也有。            柱塞泵特點：壓力等級高，可實現(xiàn)復雜的變量控制，可組成復雜的液壓系統(tǒng)。           像一般的水泵多數(shù)采用葉輪離心作用出水，但高壓水泵一般多是閥配流的柱塞泵，壓力可達到
柱塞泵是液壓系統(tǒng)的一個重要裝置。它依靠柱塞在缸體中往復運動，使密封工作容腔的容積發(fā)生變化來實現(xiàn)吸油、壓油。柱塞泵具有額定壓力高、結(jié)構(gòu)緊湊、效率高和流量調(diào)節(jié)方便等優(yōu)點，被廣泛應用于高壓、大流量和流量需要調(diào)節(jié)的場合，諸如液壓機、工程機械和船舶中。
柱塞泵是往復泵的一種，屬于體積泵，其柱塞靠泵軸的偏心轉(zhuǎn)動驅(qū)動，往復運動，其吸入和排出閥都是單向閥。當柱塞外拉時，工作室內(nèi)壓力降低，出口閥關(guān)閉，低于進口壓力時，進口閥打開，液體進入；柱塞內(nèi)推時，工作室壓力升高，進口閥關(guān)閉，高于出口壓力時，出口閥打開，液體排出。當傳動軸帶動缸體旋轉(zhuǎn)時，斜盤將柱塞從缸體中拉出或推回，完成吸排油過程。柱塞與缸孔組成的工作容腔中的油液通過配油盤分別與泵的吸、排油腔相通。變量機構(gòu)用來改變斜盤的傾角，通過調(diào)節(jié)斜盤的傾角可改變泵的排量。
柱塞泵柱塞往復運動總行程L是不變的，由凸輪的升程決定。柱塞每循環(huán)的供油量大小取決于供油行程,供油行程不受凸輪軸控制是可變的。供油開始時刻不隨供油行程的變化而變化。轉(zhuǎn)動柱塞可改變供油終了時刻，從而改變供油量。柱塞泵工作時，在噴油泵凸輪軸上的凸輪與柱塞彈簧的作用下，迫使柱塞作上、下往復運動，從而完成泵油任務(wù)，泵油過程可分為以下三個階段。
當凸輪的凸起部分轉(zhuǎn)過去后，在彈簧力的作用下，柱塞向下運動，柱塞上部空間（稱為泵油室）產(chǎn)生真空度，當柱塞上端面把柱塞套上的進油孔打開后，充滿在油泵上體油道內(nèi)的柴油經(jīng)油孔進入泵油室，柱塞運動到下止點，進油結(jié)束。

力士樂A4V柱塞泵變量原理就是通過LS（負載敏感）來控制,當執(zhí)行元件壓力變化時,LS把執(zhí)行元件的壓力情況反饋給泵上的LS閥,LS閥給力士樂A4V柱塞泵變量泵里的柱塞施加壓力,改變斜盤的角度,從而實現(xiàn)變量.當系統(tǒng)有多個執(zhí)行元件時,取壓力zui大的執(zhí)行元件
變量泵的變量控制我知道的一般有兩種形式，1：電控；2液控。電控大多采用電比例信號控制比例閥的開口量，通過變量油缸從而改變斜盤角度達到變量目的。液控形式與電控原理沒有本質(zhì)區(qū)別。只是閥的控制形式改為液控。亦稱LS。有隨動伺服的也有壓力反饋控制的。
