德國(guó)力士樂(lè)A4VG系列高壓柱塞泵技術(shù)參數(shù)和特點(diǎn)

Rexroth-排量從28到250
-常用壓力400bar（40Mpa）
-尖峰壓力450bar（45Mpa）
力士樂(lè)A4VG特點(diǎn)：
斜盤式軸向柱塞變量泵，用于閉式回路靜液壓傳動(dòng)
◆流量與驅(qū)動(dòng)轉(zhuǎn)速及排量成正比并可無(wú)級(jí)變量；
◆流量隨斜盤擺角從零增加到其zui大值；
◆使斜盤擺過(guò)中位可以平穩(wěn)改變液流流動(dòng)方向；
◆易與各種控制和調(diào)節(jié)系統(tǒng)匹配的多種變量方式；
◆泵在高壓油側(cè)配備兩個(gè)溢流閥來(lái)保護(hù)靜液壓傳動(dòng)（泵和馬達(dá)）免于超載；
◆高壓溢流閥同時(shí)也具有補(bǔ)油閥的功能；
◆內(nèi)置輔助泵用作補(bǔ)油泵和控制泵；
◆zui高補(bǔ)油壓力由一個(gè)內(nèi)置補(bǔ)油溢流閥來(lái)限制；
◆全系列帶有內(nèi)置壓力切斷閥；
典型應(yīng)用：
混凝土泵車、重型液壓平板車、液壓泵站
技術(shù)參數(shù)：
數(shù)值表（理論值，未考慮ηmh和ηv；數(shù)值經(jīng)過(guò)圓整）
1）極限zui高轉(zhuǎn)速：- 功耗為角功率的一半（例如當(dāng)Vg man和PN/2時(shí)
2）高歇zui高轉(zhuǎn)速：- 在高速空載運(yùn)行時(shí)
- 在發(fā)動(dòng)機(jī)超速期間：△p＝70...150 bar 和 Vg max
- 在反向尖峰負(fù)載時(shí)：△p＜300 bar和 t ＜ 5 秒。
