液压柱塞泵靠气压供油的液压油箱，在每次发动机器后，有必要等液压渍箱到达运用气压后，才干操作机械。直轴斜盘式柱塞泵分为压力供油型的自吸油型两种。压力供油型液压泵大都选用有气压的油箱，也有液压泵自身带有补油分泵向液压泵进油口供给压力油的。自吸油型液压泵的自吸油才干很强，无需外力供油。对于自吸油型柱塞泵，液压油箱内的油液不得低于油标下限，要坚持足够数量的液压油。液压油的清洁度越高，液压泵的运用寿命越长。9510290348AZ-P-F-12-011-RRR20KB9510290349AZ-P-F-12-014-RRR20KB9510290350AZ-P-F-12-016-RRR20KB9510290351AZ-P-F-12-019-RRR20KB9510290352AZ-P-F-12-022-RRR20KB9510290353AZ-P-F-12-008-LRR12MB-S03549510290354AZ-P-F-12-011-LRR12MB-S03549510290355AZ-P-F-12-016-LRR12MB-S03549510290356AZ-P-F-12-022-LRR12MB-S03549510290357AZ-P-F-12-019-LRR12MB-S03549510290358AZ-P-F-12-008-LPR12MB-S03549510290359AZ-P-F-12-014-LRR12KB9510290360AZ-P-F-12-004-RRR12KB9510290361AZ-P-F-12-005-RRR12KB9510290362AZ-P-F-12-008-RRR12KB9510290363AZ-P-F-12-011-RRR12KB9510290364AZ-P-F-12-014-RRR12KB9510290365AZPF-12-016RRR12PB-SO5569510290366AZ-P-F-12-019-RRR12KB9510290367AZ-P-F-12-004-LRR12KB9510290368AZ-P-F-12-005-LRR12KB)
