磁力齒輪泵油封被衝出的原因

    磁力齒輪泵油封被衝出的原因：

    出chu現xian此ci種zhong現xian象xiang大da多duo與yu液ye壓ya油you清qing潔jie度du有you關guan，如ru油you液ye選xuan用yong不bu正zheng確que或huo使shi用yong中zhong油you液ye的de清qing潔jie度du達da不bu到dao標biao準zhun要yao求qiu，均jun會hui加jia速su泵beng內nei部bu磨mo損sun
，導dao致zhi那na泄xie。因yin此ci
，應ying選xuan用yong含han有you添tian加jia劑ji的de礦kuang物wu液ye壓ya油you，這zhe樣yang可ke以yi防fang止zhi油you液ye氧yang化hua和he產chan生sheng氣qi泡pao。油you液ye的de粘zhan度du標biao準zhun為wei（16～80）×10-6m2/s過濾精度為：輸入油路小於60цm。通tong過guo觀guan察cha故gu障zhang齒chi輪lun泵beng的de軸zhou套tao和he側ce板ban發fa現xian
，若ruo所suo有you油you液ye的de清qing潔jie度du差cha均jun會hui導dao致zhi摩mo擦ca副fu表biao麵mian產chan生sheng明ming顯xian的de溝gou痕hen，而er正zheng常chang磨mo損sun的de齒chi輪lun泵beng密mi封feng麵mian上shang隻zhi會hui產chan生sheng均jun勻yun麵mian痕hen。

   （1）磁力齒輪泵旋向不對。當泵的旋向不正確時，高壓油會直接通到油封處，由於一般低壓骨架油封最多隻能承受0.5MPa的壓力，因此將使油封被衝出。
