What is the effect of using an automatic concrete mixer in case of engine error?
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.
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.
Many drivers just know about this car. Similarly, if the engine speed is too low, the engine will be damaged due to poor slip.
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.
These are the effects of the wrong use of the engine in the automatic concrete mixer. Do you understand?
