混凝土自動上料攪拌車發動機大修的條件
Conditions for engine overhaul of automatic concrete loading mixer
混凝土自動上料攪拌車在使用后長時間不可避免地會損壞,在什么條件下應該對發動機進行大修?一起來看看吧。
The automatic concrete loading mixer will inevitably be damaged for a long time after use. Under what conditions should the engine be overhauled? Let's have a look.
一.氣缸內徑過度磨損。圓度偏差為0.04-0.06mm,圓柱度偏差為0.08-0.12mm(通常,測量圓柱體的下半部分和上半部分之間的差值)。對于多缸發動機,圓度和圓柱度偏差基于具有非常大磨損的一個汽缸。
I The inner diameter of the cylinder is excessively worn. The roundness deviation is 0.04-0.06mm and the cylindricity deviation is 0.08-0.12mm (usually, measure the difference between the lower half and the upper half of the cylinder). For multi cylinder engines, roundness and cylindricity deviations are based on one cylinder with very large wear.
其次,油量顯著增加,油壓下降,排氣管發出黑色和藍色煙霧。
Secondly, the oil volume increased significantly, the oil pressure decreased, and the exhaust pipe emitted black and blue smoke.
三,混凝土運輸攪拌機的功率大幅下降。其高馬力僅為額定功率的60%左右(不包括高海拔引起的功率下降),其氣缸壓力低于標準壓力的65%。
3、 The power of concrete transportation mixer has decreased significantly. Its high horsepower is only about 60% of the rated power (excluding the power drop caused by high altitude), and its cylinder pressure is lower than 65% of the standard pressure.
四,曲軸磨損過多,曲軸磨損后曲軸的圓度和圓柱度偏差超過使用限度,或圓度和錐度限制在0.10mm。
4、 The crankshaft is excessively worn. After the crankshaft is worn, the roundness and cylindricity deviation of the crankshaft exceeds the service limit, or the roundness and taper are limited to 0.10mm.
五.當發動機啟動或停止時,如果溫度為50 ^ -60°C,水溫將無法平穩啟動。
V When the engine starts or stops, if the temperature is 50 ^ - 60 ° C, the water temperature will not start smoothly.
六,發動機異?;虿僮鞑徽?。當發動機在高溫狀態下運轉時,氣缸內有噪音(活塞爆震),主軸承或連桿軸承發出嚴重的振動或敲擊聲。
6、 Abnormal engine or abnormal operation. When the engine is running at high temperature, there is noise in the cylinder (piston knock), and the main bearing or connecting rod bearing makes serious vibration or knocking sound.
