零二一三九五二九八三九]一三六五一七三三五九零】柱塞泵根據(jù)傾斜元件的不同，有斜盤(pán)式和斜軸式兩種。斜盤(pán)式是斜盤(pán)相對(duì)回轉(zhuǎn)的缸體有一傾斜角度，而引起柱塞在泵缸中往復(fù)運(yùn)動(dòng)。傳動(dòng)軸軸線和缸體軸線是一致的。這種結(jié)構(gòu)較簡(jiǎn)單，轉(zhuǎn)速較，但工作條件要求，柱塞端部與斜盤(pán)的接觸部往往是薄弱環(huán)節(jié)。斜軸式的斜盤(pán)軸線與傳動(dòng)軸軸線是一致的。它是由于柱塞缸體相對(duì)傳動(dòng)軸傾斜一角度而使柱塞作往復(fù)運(yùn)動(dòng)。流量調(diào)節(jié)依靠擺動(dòng)柱塞缸體的角度來(lái)實(shí)現(xiàn)，故有的又稱(chēng)擺缸式。它與斜盤(pán)式相比，工作可靠，流量大，但結(jié)構(gòu)復(fù)雜。
軸向柱塞泵與徑向柱塞泵比較，排出壓力，它一般可在20～50MPa范圍內(nèi)工作，效率也，徑向尺寸小、結(jié)構(gòu)緊湊、體積小、重量輕。但結(jié)構(gòu)較徑向柱塞泵復(fù)雜，加工制造要求，價(jià)格較貴。
軸向柱塞泵一般用于機(jī)床、冶金、鍛壓、礦山及起重機(jī)械的液壓傳動(dòng)系統(tǒng)中，特別廣泛地應(yīng)用于大功率的液壓傳動(dòng)系統(tǒng)中。為了提率，在應(yīng)軸向柱塞泵一般都由缸體、配油盤(pán)、柱塞和斜盤(pán)等主要零件組成。缸體內(nèi)有多個(gè)柱塞，柱塞是軸向排列的，即柱塞的線平行于傳動(dòng)軸的軸線，因此稱(chēng)它為軸向柱塞泵。但它又不同于往復(fù)式柱塞泵，因?yàn)樗闹粌H在泵缸內(nèi)做往復(fù)運(yùn)動(dòng)，而且柱塞和泵缸與斜盤(pán)相對(duì)有旋轉(zhuǎn)運(yùn)動(dòng)。柱塞以一球形端頭與斜盤(pán)接觸。在配油盤(pán)上有低壓月形溝槽，它們彼此由隔墻隔開(kāi)，一定的密封性，它們分別與泵的進(jìn)油口和出油口連通。斜盤(pán)的軸線與缸體軸線之間有一傾斜角度。
軸向柱塞泵的工作原理所示，當(dāng)電動(dòng)機(jī)帶動(dòng)傳動(dòng)軸旋轉(zhuǎn)時(shí)，泵缸與柱塞一同旋轉(zhuǎn)，柱塞頭永遠(yuǎn)保持與斜盤(pán)接觸，因斜盤(pán)與缸體成一角度，因此缸體旋轉(zhuǎn)時(shí)，柱塞就在泵缸中做往復(fù)運(yùn)動(dòng)。以圖l—40的下一柱塞為例，它從0°轉(zhuǎn)到180°，即轉(zhuǎn)到上面柱塞的位置，柱塞缸容積逐漸增大，因此液體經(jīng)配油盤(pán)的吸油口a吸人油缸；而該柱塞從180°轉(zhuǎn)到360°時(shí)，柱塞缸容積逐漸減小，因此油缸內(nèi)液體經(jīng)配油盤(pán)的出口排出液體。只要傳動(dòng)軸不斷旋轉(zhuǎn)，泵便不斷地工作。
改變傾斜元件的角度，就可以改變柱塞在泵缸內(nèi)的行程長(zhǎng)度，即可改變泵的流量。傾斜角度固定的稱(chēng)為定量泵，傾斜角度可以改變的便稱(chēng)為變量泵。
