一辆东风 EQ1092F 汽油车的空气压缩机曲轴油封经常冲坏,机油外甩。用户前后换过数次油封却无济于事。将空气压缩机总成换掉也未解决问题。据上述情况,首先检查发动机油压是否过高。经检查,怠速为147kPa,高速为392kPa,油压正常。空压机润滑油回路有无阻塞现象,拆去空压机回油管检查,无阻塞。是否油压瞬间过高所致!根据这一想法,再结合东风汽油车润滑油
A Dongfeng EQ1092F gasoline engine air compressor crankshaft seal often washed, oil thrown outside. Change the seal several times before and after the user is of no avail. Replacement of the air compressor assembly also did not solve the problem. According to the above situation, first check the engine oil pressure is too high. After examination, idling at 147kPa, high-speed 392kPa, hydraulic normal. Air compressor lubricating circuit with or without blocking phenomenon, remove the air compressor back to the pipe check, non-blocking. Whether the oil pressure is too high! According to this idea, combined with Dongfeng gasoline engine lubricants
