力士樂比例閥華北辦事處                                                                                                               力士樂Rexroth比例閥在使用過程中,應注意對感載比例閥的檢查調(diào)整.當感載彈簧過松時,后輪制動力就會減小,此時應調(diào)整感載彈簧,但不可調(diào)得過緊,否則會使后輪制動力太大而失去側(cè)向控制能力,發(fā)生甩尾。正確的調(diào)整方法是.在平坦的地面上使車身落地,車輛空載,調(diào)整感載彈簧,使杠桿與活塞間無間隙即可.在有條件的情況下,可采用精確的調(diào)整方法.通過測量前后輪制動管路壓力,繪制壓力分配特性曲線,確認調(diào)整是否合格。                                                                                                                         德國力士樂比例閥的閥芯的運動是采用比例電磁鐵控制，通過改變輸入電流或者電壓信號來改變流向、流量、壓力，使輸出的壓力或流量與輸入的電流或電壓成正比。力士樂比例閥根據(jù)功能可分為比例換向閥三、比例流量閥、比例壓力閥三大類。以結(jié)構(gòu)形式劃分主要有螺旋插裝式比例閥和滑閥式比例閥。                                                                                                                                  4WRKE25E350P-3X/6EG24EK31/A1D3M,
