威格士叶片泵功能
性能
这种成本效益高的泵在 210 bar(3000 psi)的工作压力下提供 90% 以上的容积效率和低至62 dB(A)噪声级。通过更换泵机芯的就地修理可缩短停工时间以提高生产率。
一般说明
子母叶片泵提供长寿命、高生产率和应用灵活性。极低的噪声级适应要求最高的工业用途。尺寸紧凑和使用简便使设备设计有最大的灵活性。单联泵、双联泵和通轴驱动泵有货。
特征和优点
在紧凑的外形尺寸里实现高工作压力的能力，保证功率重量比高而安装成本降低。子母叶片机构固有的低噪声特性，提高操作者的舒适性。12叶片制保证流量脉动的振幅小，系统噪声特性低。设计成防止内部感生的轴和轴承的径向载荷的液压平衡保证长寿命。
通过消除双轴伸电动机或通过减少电动机和
驱动联轴器的数量，双联泵和通轴驱动配置节省安装位置和成本。通轴驱动型提供宝贵的回路设计灵活性，例如在单个输入驱动上实现定量和变量型。16 种流量排量和实现高工作压力的能力为你的流量和压力要求的整个范围提供最佳选择和单一货源能力。工厂试验过的机芯套件经安装后提供新泵的性能。进油口和出油口互相可以取向成四种不同的相对位置，提供很大的安装灵活性并便于机器设计。
威格士叶片泵的管理要点
叶片泵是转子槽内的叶片与泵壳(定子环)相接触，将吸入的液体由进油侧压向排油侧的泵。 叶片泵的管理要点除需防干转和过载、防吸入空气和吸入真空度过大外，还应注意: 泵转向改变，则其吸排方向也改变叶片泵都有规定的转向，不允许反。因为转子叶槽有倾斜，叶片有倒角，叶片底部与排油腔通，配油盘上的节流槽和吸、排口是按既定转向设计。 小型泵-0.015～0.03mm 中型泵-0.02～0.045mm 油液的温度和粘度 一般不宜超过55℃，粘度要求在17～37mm2/s之间。粘度太大则吸油困难；粘度太小则漏泄严重。可逆转的叶片泵必须专门设计。 叶片泵装配 配油盘与定子用定位销正确定位，叶片、转子、配油盘都不得装反，定子内表面吸入区部分最易磨损，必要时可将其翻转安装，以使原吸入区变为排出区而继续使用。
