A10VSO28DFR1/31R-PPA12N00柱塞泵，力士乐原装正品，***

德国力士乐A10VSO28DFR1/31R-PPA12N00柱塞泵

本产品适应于开式回路液压系统装置，基本原理为盘式柱塞泵结构。产品具有压力、流量可调节的特性，同时在工作中压力可以保持恒定、因此该泵也成为恒压变量柱塞泵。

A10VSO28DFR1变量泵结构特点：

性能指标随着科学技术的不断发展，现代设备的自动化水平越来越高。而液压传动及控制系统以其传递功率大、控制精度高、响应速度快、易于实现机电液一体化控制等优点，被广泛应用于各行各业中。对作为液压系统动力源--恒压变量柱塞泵的要求也愈来愈高。通常被选用型号包括A10VSO28DFR1/31R-PPA12N00、AA10VSO28DFR1/31R-PPA12N00。

产品结构及工作原理：

从结构图中可见，压力油通过通道a、b、c、进入变量壳体下腔d，由此通过通导e分别进入通导f、h，当弹簧的作大于通道f进入伺服下端弧形面积的液压推力时，伺服压在下端，压力油经h进入上腔g，推动向下，变量头偏角增大，泵的流量。反之当泵的压力克服弹簧力使伺服向上运动时，堵塞通道h，使g腔通过通道i而卸压。此时变量在下腔d的液压力作用下上移，变量头偏角减小，泵的流量。油液的进出通过泵体和配流轴上的流道，并由配流轴上吸油口控制，泵产生的液压力被静压平衡的表面所吸收。副的静压平衡采取了过平衡压力补偿，形成了开环控制。支承驱动轴的轴承只起支承作用，不受其他外力的作用。

A10VSO28DFR1/31R-PPA12N00REXROTH变量泵产品使用维护事项：

1、平时使用注意保持液压油的清洁度

2、每次停机后需要待系统冷却后再拆卸清洗

3、油泵启动前液压管路及油箱内液压油清洁度应优于***标准17/14级或NAS标准8级。

4、新泵初次使用的时候要注意排空泵内空气，注入满液压油，避免空转。

塞泵是由几个柱塞（一般为3个或6个）并列安装，用1根曲轴通过连杆滑块或由偏心轴直接推动柱塞做往复运动，实现吸、排液体的液压泵。它们也都采用阀式配流装置，而且大多为定量泵。煤矿液压支架系统中的乳化液泵一般都是卧式柱塞泵。
