2.杂质含量(1)直接鉴别。如油液中有明显的金属颗粒悬浮物，用手指捻捏时会感觉到细小颗粒的存在;在光照下，若有反光闪点，说明液压元件已严重磨损;若油箱底部沉淀有大量金属屑，说明主泵或马达已严重磨损。(2)滤纸检测。对于黏度较高的液压油，可用纯净的***稀释后，再用干净的滤纸进行过滤。若发现滤纸上留存大量机械杂质(金属粉末)，说明液压元件已严重磨损。R918C02298AZPN-11-028RDC7KB-S0023R918C02295AZPN-11-022RDC7KB-S0023R918C02293AZPF-11-022RRR20KB-S0023R918C02257AZPF-12-022RRR20KBR918C02248AZPG-11-038RQ***0MBR918C02246AZPG-11-032RQ***0MBR918C02215AZPN-11-025RCB20MBR918C02200AZPF-12-022RCB20KBR918C02184AZPG-11-045RCB20MBR918C02178AZPG-11-028RCB20MBR918C01919AZPFF-12-016/004LCP2020KB-S0007R918C01897AZPFF-12-016/016LCP2020KB-S0007R918C01895AZPFF-12-016/008LCP2020KB-S0007R918C01703AZPFF-10-016/005RCB2020MB德国博世REXROTH力士乐齿轮泵:质量保证，货期稳定德国原厂出售Rexroth力士乐齿轮泵产品别名：力士乐齿轮泵面向地区：***PGH3-22/016RE07VU2力士乐齿轮泵0510225006现货051011000205106653300510425009PGH3-22/016RE07VU205105253110510110302)
