技术特性:斜盘结构轴向柱塞变量泵,适用于闭式回路的静液传动。流量与驱动转速和排量成比例可无级调节。随着斜盘摆动角度增加,流量从零至最大值。当斜盘摆动经过零位时,液流方向平稳换向。良好适应性的多种形式控制和调节功能。高压侧的两个溢流阀保护液压传动元件(泵和马达)不过载,高压溢流阀同时作为补油压阀。内置辅助泵作为补油和控制油泵。通过内装的补油溢流阀限制最大补油压力。

柱塞泵具有一定的自吸能力,但自吸的高度不宜超过500mm,并且严禁在吸入管道上安装滤油器,吸入管道直径不小于推荐数值,另外自吸时一定要把泵先调至全偏角。
在转速超过1500rpm时,宜采用供油,供油压力为0.7MPa左右。在开式系统中,供油泵的流量应为该泵的130%,在闭式系统中,供油泵的流量应为该泵的35%。

德国BOSCH内啮合齿轮泵生产的支撑块浮动式内啮合齿轮泵，内外齿轮均采用修正渐开线齿形，用活动月牙板将高、低压腔分开，并在径向形成压力补偿，使得内外齿齿顶与月牙板之间形成几无间隙的密封，轴向动补偿盘则保证轴向间隙的良好密封，使得该泵的内泄漏减至zui低。低压12Mpa、中压21 Mpa、高压33 Mpa。此结构容积效率高、结构复杂，制造成本高。他适用于输送各种轻质、挥发性液体，直至重质、粘稠液体，甚至半固态液体。广泛应用于石油、化工、油脂、涂料等行业。
