(一)柴油机过热的检测及其危害1.检测柴油箱内的柴油温度:根据试验,正常工作1小时后的柴油温度高于环境温度14～16℃。如果高于20℃时,可视为柴油机温度过高。2.检测水箱里冷却水的耗水量:正常情况下,冷却水每小时耗量为1.5千克,如果每小时耗水量超过2.5千克,可视为柴油机温度过高。3.检测水箱里冷却水沸腾时间:一般情况下,空负荷额定转速运转,在室温情况下, 20分钟左右沸腾。如果在15分钟以内沸腾,即可视为柴油机温度过高。4.检测机油温度:机油正常温度为70～90℃,如果经常在95℃以上,可视为柴油机温度过高。5.检测排气管排出的废气温度:一般柴油机排出的废气温度为400～500℃。如果废气温度高
(A) the detection of diesel overheating and its hazards 1. Diesel fuel tank temperature detection: According to the test, normal working hours after the temperature of diesel oil is higher than the ambient temperature 14 ~ 16 ℃. If it is higher than 20 ℃, it can be regarded as overheating of diesel engine. 2. Detection of the water tank cooling water consumption: Under normal circumstances, the cooling water consumption of 1.5 kg per hour, if the hourly consumption of water more than 2.5 kg, can be considered as diesel engine temperature is too high. 3. Detection of water tank boiling water boiling time: Under normal circumstances, the air load rated speed operation, at room temperature, about 20 minutes boiling. If it boils within 15 minutes, it can be regarded as overheating of the diesel engine. 4. Detection of oil temperature: oil normal temperature is 70 ~ 90 ℃, if often above 95 ℃, can be considered as the diesel engine temperature is too high. 5. Detection exhaust pipe exhaust gas temperature: General exhaust emissions from diesel engine temperature of 400 ~ 500 ℃. If the exhaust temperature is high
