現(xiàn)貨力士樂(lè)A10VSO 45 DFR1/31R-VPA12N00柱塞泵

動(dòng)作介紹：

軸向柱塞變量泵原理是指一個(gè)柱塞泵上有兩個(gè)單

內(nèi)，柱塞向另一個(gè)方向運(yùn)動(dòng)時(shí)，將液體壓縮后另

一個(gè)單向閥被打開(kāi)，被吸入缸內(nèi)的液體被排出。

向閥，并且方向相反，柱塞向一個(gè)方向運(yùn)動(dòng)時(shí)缸

內(nèi)出現(xiàn)負(fù)壓，這時(shí)一個(gè)單向閥打開(kāi)液體被吸入缸

這種工作方式連續(xù)運(yùn)動(dòng)后就形成了連續(xù)供油。

改進(jìn)及效果：

改進(jìn)液壓系統(tǒng)設(shè)計(jì)。經(jīng)過(guò)多次論證，*后采用

的優(yōu)先閥與負(fù)荷傳感全液壓轉(zhuǎn)向器形式，。新系

作壓力。通過(guò)優(yōu)化計(jì)算，動(dòng)臂油缸采用標(biāo)準(zhǔn)系列

80/4。液壓泵排量由10ml/r提高為14ml/r，系統(tǒng)

統(tǒng)能夠按照轉(zhuǎn)向要求，優(yōu)先向其分配流量，無(wú)論

除了由于轉(zhuǎn)向回路供油過(guò)多而造成功率損失，提

高了系統(tǒng)效率，降了挖掘機(jī)液壓泵的工作壓力

負(fù)載大小、方向盤(pán)轉(zhuǎn)速高均能供油充足，

剩余部分可全部供給工作裝置回路使用，從而消

。優(yōu)化設(shè)計(jì)動(dòng)臂油缸和液壓泵造型，降系統(tǒng)工

調(diào)定壓力為14MPa，滿足了動(dòng)臂油缸舉升力和速

度要求。
