德國力士樂A4VG系列高壓柱塞泵技術(shù)參數(shù)和特點
Rexroth-排量從28到250
-常用壓力400bar(40Mpa)
-尖峰壓力450bar(45Mpa)
力士樂A4VG特點:
斜盤式軸向柱塞變量泵,用于閉式回路靜液壓傳動
◆流量與驅(qū)動轉(zhuǎn)速及排量成正比并可無級變量;
◆流量隨斜盤擺角從零增加到其zui大值;
◆使斜盤擺過中位可以平穩(wěn)改變液流流動方向;
◆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)配備兩個溢流閥來保護靜液壓傳動(泵和馬達)免于超載;
◆高壓溢流閥同時也具有補油閥的功能;
◆內(nèi)置輔助泵用作補油泵和控制泵;
◆zui高補油壓力由一個內(nèi)置補油溢流閥來限制;
◆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)過圓整)
1)極限zui高轉(zhuǎn)速:- 功耗為角功率的一半(例如當Vg man和PN/2時
2)高歇zui高轉(zhuǎn)速:- 在高速空載運行時
- 在發(fā)動機超速期間:△p=70...150 bar 和 Vg max
- 在反向尖峰負載時:△p<300 bar和 t < 5 秒。
