              轉向助力泵的性能特點
              添加時間:2019-09-08 20:47
              汽車動力轉向油泵汽車轉向系統的一種高性能動力源,轉向系統的
              “心臟”部位。它具有轉速范圍寬、輸出流量穩定、壓力脈動小、噪聲低、
              防止系統過載等特點,被廣泛用于各類轎車、客車、皮卡、輕卡車、載重車
              及工程機械中。
              本系統轉向葉片泵主要零件有定子、轉子、配流盤、葉片、泵體、主軸
              后蓋等,泵體內裝有流量控制閥和安全閥,當泵工作時通過滑潤的控制作
              用,使流量始終保持規定要求,多余的油液回流至吸油腔內;若油路發生堵
              塞或意外,系統壓力超過泵的最大壓力時,安全閥打開,滑閥全部開啟,所
              有壓力油均回到吸油腔,對系統起了安全保護作用。
