雙作用葉片泵PV7-1X/25-45RE01MC7-08WG R900751356的工作原理
    PV7-1X/25-45RE01MC7-08WG R900751356它的作用原理和單作用葉片泵相似，不同之處只在于定子表面是由兩段長(zhǎng)半徑圓弧、兩段短半徑圓弧和四段過(guò)渡曲線八個(gè)部分組成，且定子和轉(zhuǎn)子是同心的。在圖示轉(zhuǎn)子順時(shí)針?lè)较蛐D(zhuǎn)的情況下，密封工作腔的容積在左上角和右下角處逐漸增大，為吸油區(qū)，在左下角和右上角處逐漸減小，為壓油區(qū)；吸油區(qū)和壓油區(qū)之間有一段封油區(qū)把它們隔開(kāi)。這種泵的轉(zhuǎn)子每轉(zhuǎn)一轉(zhuǎn)，每個(gè)密封工作腔完成吸油和壓油動(dòng)作各兩次，所以稱(chēng)為雙作用葉片泵。泵的兩個(gè)吸油區(qū)和兩個(gè)壓油區(qū)是徑向?qū)ΨQ(chēng)的，作用在轉(zhuǎn)子上的液壓力徑向平衡，所以又稱(chēng)為平衡式葉片泵。
PV7-1X/25-45RE01MC7-08WG R900751356雙作用葉片泵的瞬時(shí)流量是脈動(dòng)的，當(dāng)葉片數(shù)為4的倍數(shù)時(shí)脈動(dòng)率小。為此，雙作用葉片泵的葉片數(shù)一般都取12或16。 PV7-1X/100-118RE07MC0-16

PV7-1X/25-45RE01MC7-08WG R900751356葉片泵的管理要點(diǎn)除需防干轉(zhuǎn)和過(guò)載、防吸入空氣和吸入真空度過(guò)大外，還應(yīng)注意：
    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(pán)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(zhuān)門(mén)設(shè)計(jì)。
    2．葉片泵裝配 配油盤(pán)與定子用定位銷(xiāo)正確定位，葉片、轉(zhuǎn)子、配油盤(pán)都不得裝反，定子內(nèi)表面吸入?yún)^(qū)部分最易磨損，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(guò)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(guò)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。
作為泵產(chǎn)品，葉片泵更多地指滑片泵。只要你有興趣在百度搜索發(fā)現(xiàn)，葉片泵幾乎全部指滑片泵。
