单柱塞泵液压系中常见毛病可概括为四种:空负荷不能提高;重负荷不能提高;提高速度缓慢,并伴有颤动表象;提高后,当操作手柄置于中立方位时,耕具降低较快。在进行液压体系毛病分析时,可划分为两个区段:油箱、油泵为榜首区段,担负供油并把低压油成为高压油,是液压体系的动力有些;将油缸定为第二区段。一、空负荷不能提高松开油泵与油缸衔接管路接头,调查油泵作业情况。假如泵油,阐明榜首区段作业正常;反之,标明榜首区段有毛病。1.归于榜首区段毛病9510290334AZ-P-FF-12-014/014-RXC12MB-S03089510290335AZ-P-F-12-016-RPR12MV14015-S00439510290336AZ-P-F-12-016-LRR12KB9510290337AZPF-12-004LRR20KB-S00399510290338AZPF-12-005LRR20KB-S00399510290339AZ-P-F-12-008-LRR20KB9510290340AZ-P-F-12-011-LRR20KB9510290341AZ-P-F-12-14-LRR20KB9510290342AZ-P-F-12-016-LRR20KB9510290343AZ-P-F-12-019-LRR20KB9510290344AZ-P-F-12-022-LRR20KB9510290345AZPF-12-004RRR20KB-S00399510290346AZPF-12-005RRR20KB-S00399510290347AZ-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-S0354)
