VICKERS威格士20V葉片泵公司VICKERS威格(ge)(ge)士(shi)20V葉(xie)片(pian)泵(beng)高性能子母葉(xie)片(pian)泵(beng),用(yong)于工(gong)業用(yong)途(tu)威格(ge)(ge)士(shi)為(wei)工(gong)業用(yong)途(tu)提供zui齊全(quan)的液壓子母葉(xie)片(pian)泵(beng)。各種(zhong)品種(zhong)的單(dan)聯泵(beng)和多聯泵(beng)配置使你(ni)可(ke)以(yi)選擇于你(ni)用(yong)途(tu)的準確的泵(beng)或泵(beng)組。

VICKERS威(wei)格士20V葉片(pian)泵用涂黃油(you)(you)(you)的方法，逐個檢査吸油(you)(you)(you)管接(jie)頭處(chu)，若噪聲減少應緊固接(jie)頭。或直(zhi)接(jie)觀察回油(you)(you)(you)口(kou)處(chu)是(shi)否出現(xian)氣泡(pao)。

泵端密封磨損

在軸端油(you)封(feng)處(chu)涂上黃油(you)，若噪聲減小，應更換油(you)封(feng)

泵蓋螺釘由于振動(dong)而松(song)動(dong)

將螺(luo)釘連接處涂上黃油，若(ruo)噪聲小，應(ying)緊固螺(luo)釘

泵與電動機軸不同心

重新調整使之同心

轉(zhuan)子的葉片槽兩側與其兩端面不垂直

更換轉子

配油盤卸荷三角槽太(tai)短(duan)

用什錦銼適當(dang)修改，使前一葉片過卸荷(he)槽時，后一葉片已(yi)脫(tuo)離吸油腔花(hua)鍵(jian)槽軸端的密(mi)封(feng)過緊（有燙手現象）

適當調整更換

泵的轉速太高

按規定轉速使用

油泵的吸油量不足

檢(jian)查油液高度液壓(ya)油嚴重污染

拆(chai)下濾油(you)器(qi)(qi)，檢查濾油(you)器(qi)(qi)是(shi)否(fou)破(po)損，是(shi)否(fou)有較多固(gu)體吸附(fu)，更換濾油(you)器(qi)(qi)和液壓(ya)油(you)壓(ya)力振擺

檢(jian)查泵芯(xin)總壓(ya)閥(fa)閥(fa)芯(xin)磨損情況

VICKERS威(wei)格(ge)士20V葉片泵的特點

(1)改變定子和(he)轉子之(zhi)間的偏(pian)(pian)心(xin)便(bian)可(ke)改變流量(liang)。偏(pian)(pian)心(xin)反向(xiang)時,吸油壓(ya)(ya)(ya)(ya)(ya)油方(fang)向(xiang)也相(xiang)(xiang)(xiang)反;(2)處(chu)在(zai)(zai)壓(ya)(ya)(ya)(ya)(ya)油腔的葉(xie)片(pian)頂(ding)部受到壓(ya)(ya)(ya)(ya)(ya)力油的作(zuo)用(yong),該作(zuo)用(yong)要(yao)把(ba)葉(xie)片(pian)推入(ru)轉子槽(cao)內。為(wei)了使葉(xie)片(pian)頂(ding)部可(ke)靠地和(he)定子內表(biao)面相(xiang)(xiang)(xiang)接觸(chu)，壓(ya)(ya)(ya)(ya)(ya)油腔一(yi)側的葉(xie)片(pian)底部要(yao)通(tong)過特殊的溝(gou)槽(cao)和(he)壓(ya)(ya)(ya)(ya)(ya)油腔相(xiang)(xiang)(xiang)通(tong)。吸油腔一(yi)側的葉(xie)片(pian)底部要(yao)和(he)吸油腔相(xiang)(xiang)(xiang)通(tong),這里的葉(xie)片(pian)僅(jin)靠離心(xin)力的作(zuo)用(yong)頂(ding)在(zai)(zai)定子內表(biao)面上;(3)由(you)于(yu)轉子受到不平衡的徑向(xiang)液壓(ya)(ya)(ya)(ya)(ya)作(zuo)用(yong)力,所(suo)以這種泵一(yi)般(ban)不宜用(yong)于(yu)高壓(ya)(ya)(ya)(ya)(ya)。

(4)為(wei)了更有利于葉片(pian)在慣性力作用(yong)下(xia)向(xiang)(xiang)外(wai)伸出，而使葉片(pian)有一個(ge)與(yu)旋轉方向(xiang)(xiang)相反(fan)的傾(qing)斜角，稱后傾(qing)角，一般(ban)為(wei)24°。

VICKERS威格士20V葉(xie)(xie)(xie)片(pian)(pian)(pian)泵的(de)(de)工(gong)作(zuo)原(yuan)理，葉(xie)(xie)(xie)片(pian)(pian)(pian)泵由(you)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)1、定(ding)(ding)子(zi)(zi)2、葉(xie)(xie)(xie)片(pian)(pian)(pian)3和端(duan)蓋等組成(cheng)。定(ding)(ding)子(zi)(zi)具有圓柱(zhu)形(xing)內表面，定(ding)(ding)子(zi)(zi)和轉(zhuan)(zhuan)(zhuan)子(zi)(zi)間(jian)有偏(pian)心(xin)距。葉(xie)(xie)(xie)片(pian)(pian)(pian)裝在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)槽中，并可(ke)在(zai)槽內滑動(dong)，當(dang)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)回轉(zhuan)(zhuan)(zhuan)時，由(you)于離(li)心(xin)力的(de)(de)作(zuo)用(yong)，使葉(xie)(xie)(xie)片(pian)(pian)(pian)緊靠在(zai)定(ding)(ding)子(zi)(zi)內壁，這(zhe)樣在(zai)釘子(zi)(zi)、轉(zhuan)(zhuan)(zhuan)子(zi)(zi)、葉(xie)(xie)(xie)片(pian)(pian)(pian)和兩側配油盤間(jian)就形(xing)成(cheng)若干個密封的(de)(de)工(gong)作(zuo)空(kong)間(jian)，當(dang)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)按圖(tu)示的(de)(de)方(fang)向(xiang)回轉(zhuan)(zhuan)(zhuan)時，在(zai)圖(tu)的(de)(de)右部，葉(xie)(xie)(xie)片(pian)(pian)(pian)逐漸伸出，葉(xie)(xie)(xie)片(pian)(pian)(pian)間(jian)的(de)(de)工(gong)作(zuo)空(kong)間(jian)逐漸增大，從吸(xi)(xi)油口吸(xi)(xi)油，這(zhe)是吸(xi)(xi)油腔。
