使用自動混凝土攪拌機發動機錯誤情況下會有什么影響?
What is the effect of using an automatic concrete mixer in case of engine error?
一些特定的自動混凝土攪拌機司機認為發動機溫度不低,因此發動機恒溫器將被自動移除,而冷卻液只能從夜間循環中移除。由于無法調節冷卻強度,因此發動機通常在高溫條件下運行。這會導致磨損并增加燃油消耗。實際上,高溫對發動機有害。為了確保發動機的使用壽命,應將安裝自動混凝土攪拌車的用例限制在環境溫度范圍內。
Some specific automatic concrete mixer drivers believe that the engine temperature is not low, so the engine thermostat will be automatically removed, and the coolant can only be removed from the night cycle. Since the cooling intensity cannot be adjusted, the engine is usually operated at high temperature. This causes wear and increases fuel consumption. In fact, high temperature is harmful to the engine. In order to ensure the service life of the engine, the use case of installing automatic concrete mixer truck should be limited to the ambient temperature range.
橡皮筋很好。如果皮帶太松,不僅會拉伸并損壞皮帶,縮短皮帶的使用壽命,而且過大的壓力會自動加載并扭曲攪拌器的發電機軸和泵軸,從而損壞攪拌器。為了滿足技術要求,必須松開自動混凝土攪拌車的風扇皮帶。建議的組裝偏差為10-15毫米。
The rubber band is good. If the belt is too loose, it will not only stretch and damage the belt, shorten the service life of the belt, but also automatically load and twist the generator shaft and pump shaft of the mixer by excessive pressure, which will damage the agitator. In order to meet the technical requirements, the fan belt of the automatic concrete mixer must be loosened. The recommended assembly deviation is 10-15mm.
許多駕駛員知道這輛車剛剛起步。同樣,如果發動機轉速過低,則由于打滑不良會損壞發動機。
Many drivers just know about this car. Similarly, if the engine speed is too low, the engine will be damaged due to poor slip.
但是,大多數人都知道自動混凝土攪拌機中的油泵無法快速潤滑光滑表面上的潤滑劑,因為由于加熱速度較慢,它們將在短時間內處于閑置狀態。同時,由于高溫燃油霧化不足,燃燒的燃油進入曲軸箱,沖刷了氣缸壁上的油膜,并加速了零件的磨損。因此,在自潤滑發動機啟動后幾秒鐘的高溫條件下,有必要改善空轉加熱并提高發動機滑移率。
However, most people know that the pumps in automatic concrete mixers cannot quickly lubricate lubricants on smooth surfaces because they will be idle for a short time due to the slow heating rate. At the same time, due to insufficient atomization of high temperature fuel, the combustion fuel enters the crankcase, washes the oil film on the cylinder wall, and accelerates the wear of parts. Therefore, it is necessary to improve the idling heating and increase the slip ratio of the engine under the high temperature condition of a few seconds after the start-up of the self-lubricating engine.
自動混凝土攪拌機錯誤使用發動機的影響就是這些,你了解了嗎?
These are the effects of the wrong use of the engine in the automatic concrete mixer. Do you understand?
