(7)柱塞卡死在泵体里,用手扳动聚散手柄,凭感受判别柱塞是不是卡死。假如别离轻松,阐明柱塞弹簧处于紧缩状态,柱塞现已卡死在泵体里。柱塞卡死的缘由有三:①油泵作业时间较长,负荷较大,或长期“空泵”,或合作空隙过小,光滑不良,温度过***缘由均可形成柱塞卡死。假如拉伤严峻,应替换新泵;假如拉伤细微,运用细砂布把拉伤处磨光,可持续运用。②新装置的油泵容易发作柱塞卡死表象,这主要是固定油泵的三个螺栓拧紧力矩不一致形成的,可把三个螺栓略微拧紧。使油泵方位细微移动,然后均匀拧紧三个螺栓即可。③液压油里杂质较多,使柱塞与泵体合作面损害而卡死。9510290347AZ-P-F-12-008-RRR20KB9510290348AZ-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-LRR12KB9510290369AZ-P-F-12-008-LRR12KB9510290370AZ-P-F-12-011-LRR12KB9510290371AZ-P-F-12-019-LRR12KB)
