1、液压系统中，固体颗粒污染会导致：加剧液压元件的表面腐蚀和磨损，增大***量，油温升高、压力降低、效率低、响应慢、不稳定、改变运动方向，运动速度减低，承载能力下降，阀芯卡死，烧毁电磁线圈。2、液压系统中，水污染会导致：油变质(如添加剂析出及油的氧化)，润滑油膜变薄，腐蚀并加速金属表面疲劳失效，低温产生冷却、淤塞运动元件，绝缘油的绝缘强度降低。R918C02740AZPNF-11-032/014LDC0720KB-S0023R918C02614AZPNF-11-022/008RDC720KB-S0023R918C02598AZPNN-11-025/022RDC77KB-S0023R918C02594AZPNF-11-032/016RDC720KB-S0023R918C02591AZPNF-11-032/008RDC720KB-S0023R918C02478AZPF-10-022RSG20PB-S0012R918C02445AZPG-11-038LDC7KB-S0023R918C02440AZPN-11-025LDC7KB-S0023R918C02383AZPF-22-022LRR20MBR918C02381AZPF-21-022LFB20MBR918C02310AZPF-22-022RHO30KBR918C02301AZPG-11-038RDC7KB-S0023R918C02300AZPN-11-032RDC7KB-S0023R918C02298AZPN-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-S0007)
