REXROTH柱塞泵天津代理                                                                                                          力士樂REXROTH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)保持與斜盤接觸,因斜盤與缸體成一角度,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。傾斜角度固定的稱為定量泵,傾斜角度可以改變的便稱為變量泵             REXROTH力士樂軸向柱塞泵與徑向柱塞泵比較,排出壓力高,它一般可在20~50MPa范圍內(nèi)工作,效率也高,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,加工制造要求高,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、柱塞和斜盤等主要零件組成。缸體內(nèi)有多個(gè)柱塞,柱塞是軸向排列的,即柱塞的中心線平行于傳動(dòng)軸的軸線,因此稱它為軸向柱塞泵。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相對(duì)有旋轉(zhuǎn)運(yùn)動(dòng)。柱塞以一球形端頭與斜盤接觸。在配油盤上有高低壓月形溝槽,它們彼此由隔墻隔開,保證一定的密封性,它們分別與泵的進(jìn)油口和出油口連通。斜盤的軸線與缸體軸線之間有一傾斜角度。        R910998825 AEA4VSO125DR/30R-PPB13N00
