REXROTH軸向柱塞泵A4VSO355DR/30R-PPB13N00

進(jìn)油過程

當(dāng)凸輪的凸起部分轉(zhuǎn)過去后，在彈簧力的作用下，柱塞向下運(yùn)動(dòng)，柱塞上部空間（稱為泵油室）產(chǎn)生真空度，當(dāng)柱塞上端面把柱塞套上的進(jìn)油孔打開后，充滿在油泵上體油道內(nèi)的柴油經(jīng)油孔進(jìn)入泵油室，柱塞運(yùn)動(dòng)到下止點(diǎn)，進(jìn)油結(jié)束

回油過程

柱塞向上供油，當(dāng)上行到柱塞上的斜槽（停供邊）與套筒上的回油孔相通時(shí)，泵油室低壓油路便與柱塞頭部的中孔和徑向孔及斜槽溝通，油壓驟然下降，出油閥在彈簧力的作用下迅速關(guān)閉，停止供油。此后柱塞還要上行，當(dāng)凸輪的凸起部分轉(zhuǎn)過去后，在彈簧的作用下，柱塞又下行。此時(shí)便開始了下一個(gè)循環(huán)。

柱塞泵以一個(gè)柱塞為原理介紹，一個(gè)柱塞泵上有兩個(gè)單向閥，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)單向閥打開液體被吸入缸內(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，被吸入缸內(nèi)的液體被排出。這種工作方式連續(xù)運(yùn)動(dòng)后就形成了連續(xù)供油。

泵的泵油機(jī)構(gòu)包括兩套準(zhǔn)確偶件：柱塞（plunger） 柱塞套(barrel)構(gòu)成柱塞偶件(plunger and barrel assembly)（圖5-11）、出油閥（delivery valve）和出油閥座(delivery valve seat)構(gòu)成出油閥偶件(delivery valve assembly

柱塞和柱塞套是一對(duì)準(zhǔn)確偶件，經(jīng)配對(duì)研磨后不能互換，要求有高的精度和光潔度和好的耐磨性，其徑向間隙為0.002～0.003mm

柱塞頭部圓柱面上切有斜槽，并通過徑向孔、軸向孔與頂部相通，其目的是改變循環(huán)供油量；柱塞套上制有進(jìn)、回油孔，均與泵上體內(nèi)低壓油腔相通，柱塞套裝入泵上體后，應(yīng)用定位螺釘定位。

-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。

泵安裝要求

1.泵轉(zhuǎn)向改變，則其吸排方向也改變?nèi)~片泵都有規(guī)定的轉(zhuǎn)向，不允許反。因?yàn)檗D(zhuǎn)子葉槽有傾斜，葉片有倒角，葉片底部與排油腔通，配油盤上的節(jié)流槽和吸、排口是按既定轉(zhuǎn)向設(shè)計(jì)�？赡孓D(zhuǎn)的葉片泵必須專門設(shè)計(jì)。

2.葉片泵裝配配油盤與定子用定位銷正確定位，葉片、轉(zhuǎn)子、配油盤都不得裝反，定子內(nèi)表面吸入?yún)^(qū)部分較易磨損，必要時(shí)可將其翻轉(zhuǎn)安裝，以使原吸入?yún)^(qū)變?yōu)榕懦鰠^(qū)而繼續(xù)使用。

3.拆裝 注意工作表面清潔，工作時(shí)油液應(yīng)很好過濾。

4. 葉片在葉槽中的間隙太大會(huì)使漏泄增加，太小則葉片不能自由伸縮，會(huì)導(dǎo)致工作失常。

5.葉片泵的軸向間隙 對(duì)ηv影響很大。

1)小型泵-0.015～0.03mm

2)中型泵-0.02～0.045mm

6.油液的溫度和粘度 一般不宜超過55℃，粘度要求在17～37mm2/s之間。粘度太大則吸油困難;粘度太小則漏泄嚴(yán)重。
