将195型柴油机通气管式通风装置改为负压阀式,在正时齿轮室盖安装负压阀式呼吸器(见右图),可以使曲轴箱负压值达14厘米水柱以上,从而减轻和制止机油从调速杠杆臂、减压器螺钉、油封、正时齿轮室盖等结合而处漏油;制止机油上窜到燃烧室;降低机油温度。去年奉化县改装987台,实际使用一般可节约机油20～35%,并能延长机油使用期。呼吸器可用浙江省慈溪动力机厂生产的165F柴油机新加油塞(每只0.66元)。
The 195 diesel engine ventilation tube ventilation device to negative pressure valve, the timing gear chamber cover installed negative pressure valve respirator (see right), can make the crankcase negative pressure value of 14 cm above the water column, thereby reducing And to stop the oil from the throttle lever arm, reducer screw, oil seal, timing gear chamber cover and other combinations of oil leakage; to stop the oil on the channeling to the combustion chamber; reduce oil temperature. Last year, Fenghua modified 987 units, the actual use of general can save 20 to 35% oil, and can extend the service life of oil. Respirator available Zhejiang Cixi Power Plant 165F diesel engine new plug (0.66 yuan each).
