油泵A4VG71DA2D3L/32R-NZF02F001S特性

Rexroth液壓泵的工作原理是為液壓傳動(dòng)提供加壓液體的一種液壓元件，是泵的一種。它的功能是把動(dòng)力機(jī)（如電動(dòng)機(jī)和內(nèi)燃機(jī)等）的機(jī)械能轉(zhuǎn)換成液體的壓力能。圖中為單柱塞泵的工作原理。凸輪由電動(dòng)機(jī)帶動(dòng)旋轉(zhuǎn)。當(dāng)凸輪旋轉(zhuǎn)至曲線的下降部位時(shí)，彈簧迫使柱塞向下，形成一定真空度，油箱中的油液在大氣壓力的作用下進(jìn)入密封容積。凸輪使柱塞不斷地升降，密封容積周期性地減小和增大，泵就不斷吸油和排油。

-斜軸結(jié)構(gòu)向柱塞變量泵，用于開式回路的靜液壓傳動(dòng)

-流量與驅(qū)動(dòng)轉(zhuǎn)速和排量成比例。通過調(diào)節(jié)斜軸可無級(jí)調(diào)節(jié)流量

-斜軸結(jié)構(gòu)向維形柱塞旋轉(zhuǎn)組

-無級(jí)可變排量

-結(jié)構(gòu)緊湊固的軸承系統(tǒng)，使用壽命長(zhǎng)

-可選擇長(zhǎng)壽命軸承

-良好的性能重量比

-低飛輪效應(yīng)

-控制裝置產(chǎn)品系列豐富

Pabs max---------------------------------------8 bar

進(jìn)油壓力決定LR功率特性及LR.H和LR.N控制特性的起點(diǎn)。

控制起點(diǎn)由制造商設(shè)定為Pabs=1 bar

進(jìn)油壓力的增加導(dǎo)致控制起點(diǎn)升高，因此使控制特性產(chǎn)生平行移位。

此變化的詳細(xì)信息可根據(jù)要求提供。

出油壓力范圍

油口A或B處的壓力

公稱壓力Pn--------------------------------------350 bar

峰值壓力Pmax----------------------------------400 bar
