1)向液压泵和马达壳休内通油进行冷却，忌讳使壳体内压力偏高。有时需求向液压泵和马达的壳体通油，以便使液压泵和马达得到冷却，这是必要的。但牢记不要使壳体内油的压力偏高，不然，将会致使液压泵和马达轴封的损坏，同时对有的柱塞泵还会添加吸油腔柱塞向外伸出的阻力。2)当液压泵经常在零偏心或体系工作压力低于8MPa时工作，使液压泵的漏损过小而引起泵体发热时，可选用油路强行循环冷却。R918C02614AZPNF-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)
