3、吸入带有空气的油液进口液压泵|吸入了带有空气的油液是对其软寿数影响***大一个要素。当空气进入到液压泵配流区从低压区转换到高压区时‚在高压油的挤压下‚气泡***决裂‚就会对缸体配流面与配流盘间形成穴蚀现象。当穴蚀严重时会使缸体面铜层距离区窜通。另一种情况是液压油箱容积小或是油箱内距离板规划不合理‚液压体系回油时所带入到油液中的空气气泡还没有被完全消出时就被泵吸油口吸走了‚也会形成上述病因。R900932141PGH4-2X/032RE11VU2R900932140PGH4-2X/025RE11VU2R900932139PGH4-2X/020RE11VU2R900245596PGH4-2X/025RE11VU2-A280BR900204884PGH5-2X/200RE07VE4-A388R900064616PGH3-1X/010LE07MU2R900061672PGH2-1X/006RE07ME4R900057641PGH5-2X/250RE07VU2-A388R900086557PGH5-2X/200RE07VE4R900086556PGH5-2X/160RE07VE4R900086518PGH5-2X/125RR11VU2R900086321PGH4-2X/040RE11VU2PGH4-2X/032RE11VU2力士乐REXROTH齿轮泵力士乐液压元件分类动力元件：齿轮泵,叶片泵,柱塞泵,螺杆泵；执行元件：液压缸,活塞液压缸,柱塞液压缸,摆动液压缸,组合液压缸；液压马达：齿轮式液压马达,叶片液压马达,柱塞液压马达；控制元件：方向控制阀,单向阀,换向阀；压力控制阀：溢流阀,减压阀,顺序阀,压力继电器等；流量控制阀：节流阀,调速阀,分流阀；R901137885PGF1-2X/2,8RE01VP1R901125550PGF2-2X/011RN20VM-A457R901125549PGF2-2X/006RN20VM-A457R901103807PGF3-3X/022RJ20VU2R901067539PGF2-2X/006RA01VP2-A381)
