力士樂(lè)比例閥華北辦事處                                                                                                               力士樂(lè)Rexroth比例閥在使用過(guò)程中,應(yīng)注意對(duì)感載比例閥的檢查調(diào)整.當(dāng)感載彈簧過(guò)松時(shí),后輪制動(dòng)力就會(huì)減小,此時(shí)應(yīng)調(diào)整感載彈簧,但不可調(diào)得過(guò)緊,否則會(huì)使后輪制動(dòng)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(chē)身落地,車(chē)輛空載,調(diào)整感載彈簧,使杠桿與活塞間無(wú)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(guò)測(cè)量前后輪制動(dòng)管路壓力,繪制壓力分配特性曲線,確認(rèn)調(diào)整是否合格。                                                                                                                         德國(guó)力士樂(lè)比例閥的閥芯的運(yùn)動(dòng)是采用比例電磁鐵控制，通過(guò)改變輸入電流或者電壓信號(hào)來(lái)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(lè)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(lèi)。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,
