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。有时需要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。但切记不要使壳体内油的压力偏高，否则，将会致使液压泵和马达轴封的损坏，一起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疼或体系工作压力低于8MPa时工作，使液压泵的漏损过小而致使泵体发热时，可选用油路强行循环冷却。0510525324AZPF-12-011LRR20MB0510625013AZPF-10-019RCB20MB0510425009AZPF-10-008RCB20MBR918PT0550AZPS-22-022RPR20MBR918C03771AZPS-11-008RCB20MBR918C02883AZPGF-11-038/004RCB2020MBR918C02771AZPGG-12-028/028LDC2020MBR918C02740AZPNF-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-22-022RHO30KB)
