KRACHT齒輪泵KF80RF1-D15困油現(xiàn)象危害
閱讀:659 發(fā)布時間:2022-6-16KRACHT齒輪泵KF80RF1-D15 困油現(xiàn)象危害:軸承負(fù)荷增大、功率損失增大、油液發(fā)熱、引起噪音和振動、影響油泵的工作性能、平穩(wěn)性和壽命。
說明:封閉空間的容積是動態(tài)變化的,由大變小再由小變大。變小時:油液不可壓縮,油液被擠壓,壓力升高,就從零件接合面的縫隙中強(qiáng)行擠出(這個壓力比油泵的工作壓力高很多,甚至可達(dá)幾百個大氣壓),使齒輪和軸承受到很大的徑向壓力和附加載荷。變大時,產(chǎn)生局部真空,空氣析出,發(fā)生氣化,引起氣蝕。
