葉片泵2520V-17A9/21A9-1AA-22R威格士2520V-17A9-1AA,圖 1 所示的泵代表了這個(gè)系列的所有單聯(lián)泵。泵主要是由進(jìn)油口蓋板、出油口殼體、驅(qū)動(dòng)軸和抽吸機(jī)芯組成。機(jī)芯的主要元件是橢圓偏心定子圈、開(kāi)槽的轉(zhuǎn)子與驅(qū)動(dòng)軸花鍵、一個(gè)進(jìn)油口和出油口的支承板、二片側(cè)板、10/12 個(gè)葉片和配在定子槽中的 10/12 個(gè)柱塞。油液通過(guò)蓋板上的進(jìn)油口進(jìn)入機(jī)芯并且通過(guò)殼體上的出油口輸出。所有的泵都設(shè)計(jì)成能夠方便地改變旋轉(zhuǎn)方向、抽吸能力和油口位置,以適應(yīng)特殊用途的需要。機(jī)芯的動(dòng)作如圖 2所示,轉(zhuǎn)子通過(guò)驅(qū)動(dòng)軸在定子圈內(nèi)被驅(qū)動(dòng),它與動(dòng)力源相聯(lián)接。隨著轉(zhuǎn)子轉(zhuǎn)動(dòng),葉片上的離心力加上葉片下來(lái)自出油口的壓力,使葉片跟隨定子圈的橢圓表面。通過(guò)偏心定子圈上的一個(gè)鉆孔,存在一個(gè)附加進(jìn)油流道,這個(gè)孔直接連接進(jìn)油口到偏心定子圈的進(jìn)口區(qū)域,并且提供一個(gè)附加流道,使油液進(jìn)入機(jī)芯。油液是被密封在葉片之間,通過(guò)一個(gè)密封的區(qū)域輸送到定子圈的出口段,當(dāng)接近出口段時(shí),容腔體積減小,油液被壓出,進(jìn)入系統(tǒng)。系統(tǒng)壓力進(jìn)入葉片下方,***在正常工作時(shí)葉片密封接觸定子圈。
