威格士葉片泵功能
性能
這種成本效益高的泵在 210 bar(3000 psi)的工作壓力下提供 90% 以上的容積效率和低至62 dB(A)噪聲級。通過更換泵機芯的就地修理可縮短停工時間以提高生產率。
一般說明
子母葉片泵提供長壽命、高生產率和應用靈活性。極低的噪聲級適應要求最高的工業用途。尺寸緊湊和使用簡便使設備設計有最大的靈活性。單聯泵、雙聯泵和通軸驅動泵有貨。
特征和優點
在緊湊的外形尺寸里實現高工作壓力的能力，保證功率重量比高而安裝成本降低。子母葉片機構固有的低噪聲特性，提高操作者的舒適性。12葉片制保證流量脈動的振幅小，系統噪聲特性低。設計成防止內部感生的軸和軸承的徑向載荷的液壓平衡保證長壽命。
通過消除雙軸伸電動機或通過減少電動機和
驅動聯軸器的數量，雙聯泵和通軸驅動配置節省安裝位置和成本。通軸驅動型提供寶貴的回路設計靈活性，例如在單個輸入驅動上實現定量和變量型。16 種流量排量和實現高工作壓力的能力為你的流量和壓力要求的整個范圍提供最佳選擇和單一貨源能力。工廠試驗過的機芯套件經安裝后提供新泵的性能。進油口和出油口互相可以取向成四種不同的相對位置，提供很大的安裝靈活性并便于機器設計。
威格士葉片泵的管理要點
葉片泵是轉子槽內的葉片與泵殼(定子環)相接觸，將吸入的液體由進油側壓向排油側的泵。 葉片泵的管理要點除需防干轉和過載、防吸入空氣和吸入真空度過大外，還應注意: 泵轉向改變，則其吸排方向也改變葉片泵都有規定的轉向，不允許反。因為轉子葉槽有傾斜，葉片有倒角，葉片底部與排油腔通，配油盤上的節流槽和吸、排口是按既定轉向設計。 小型泵-0.015～0.03mm 中型泵-0.02～0.045mm 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；粘度太小則漏泄嚴重。可逆轉的葉片泵必須專門設計。 葉片泵裝配 配油盤與定子用定位銷正確定位，葉片、轉子、配油盤都不得裝反，定子內表面吸入區部分最易磨損，必要時可將其翻轉安裝，以使原吸入區變為排出區而繼續使用。
