威格士2525V系列2525V-21A12-1AA-22R工作相对可靠,在liuliang变化很大的速度换接回路中,常将高压小liuliang泵和低压大liuliang泵并联使用。当速进给时需要liuliang很大,两个泵同时供油(此时压力较低):当工作进给时,压力较高,大liuliang泵卸荷,只有小liuliang泵供油。这与采用高压大liuliang泵相比,可以节省能源,减少油液发热。叶片泵具有liuliang均匀、运转平稳、噪声低、体积小、质量轻等优点。在机床、 液压系统、工程机械、船舶、压铸及冶金设备中得到广泛的应用。YAOZUOHYaa叶片泵主要分为单作用叶片泵和双作用叶片泵两大类。单作用叶片泵转子每转一周,只有一次吸压油过程,转子承受单方向径向力,轴承负荷大,泵的liuliang可以调节,又称为变量叶片泵;双作用叶片泵转子每转一周,有两次吸压油过程,泵的liuliang不可调节,称为定量叶片泵。按压力等级叶片泵可分为:中低压叶片泵(7MPa),中高压叶片泵(16MPa),高压叶片泵(20~30MPa)。叶片泵的工作原理,(1)单作用叶片泵的工作原理 单作用叶片泵的工作原理如图 2-3所示。转子外表面和定子内表面都是圆柱面。转子的中心与定子的中心保持一个偏心距e。在配油盘上开有吸油窗口和压油窗口,如图 2-3的虚线所示。当转子如图示方向转动时,下部两相邻叶片、定子、转子及配油盘所组成的密闭容积增大,油液通过吸油窗口吸入;而上部两相邻叶片、定子、转子及配油盘所组成的密闭容积减小,油液由压油窗口压送到压油管中去。
