一、热车。开涡轮增压车型,要有更多的耐心和更好的习惯,搅拌车冷启动后,原地让搅拌车热车,不仅仅是让水温到达正常值,也是让搅拌车发动机的机油到达的工况温度。没有油温表的车型不必担心,冷启动时,只要水温表温度到达正常工作温度时,等多1-2分钟即可。切忌启动搅拌车后马上进行高速运转,因为涡轮增压属于高速运转部件,所以更需要机油进行保护,如果还没热好车就高速行驶,机油还是比较粘稠,润滑效果不佳,马上高速运转会让发动机得不到应有保护,如果强迫涡轮以全负荷的状态工作,那么会增大涡轮磨损,缩短涡轮寿命。
1、 Hot car. It is necessary to have more patience and better habits to drive a turbocharged vehicle. After the mixer is cold started, it is not only to make the water temperature reach the normal value, but also to make the engine oil of the mixer reach the optimal working temperature. There is no need to worry about the model without oil temperature gauge. During cold start, as long as the temperature of water temperature gauge reaches the normal working temperature, wait 1-2 minutes more. Do not run at high speed immediately after starting the mixer, because turbocharging is a high-speed running part, so it needs more oil for protection. If the car is driven at high speed before it is hot, the oil is still viscous and the lubrication effect is poor. If the turbine is forced to work at full load, the turbine mill will be increased The turbine life is shortened.
二、熄火。同样的,熄火前也需要耐心多等一等,因为长时间行驶的搅拌车或者是高速行驶的搅拌车,涡轮增压器的温度都是非常高的,停车后,涡轮由于惯性还会继续运转一段时间,需要足够的时间冷却,如果停车后就马上关掉搅拌车发动机,那么冷却系统和润滑油的供应也会停止,这样会伤害到搅拌车的轴承。所以,建议熄火前先让搅拌车发动机运转2-3分钟,让涡轮增压器有足够的时间冷却。但涡轮增压器也不可长时间怠速运转,否则搅拌车涡轮增压器也会因机油压力过低而导致润滑不良,一般怠速时间不应超过10分钟。

2、 Turn off the engine. Similarly, you need to be patient before you turn off the engine, because the temperature of the turbocharger is very high for a long time or a high-speed mixer. After parking, the turbine will continue to run for a period of time due to inertia, so it needs enough time to cool down. If you turn off the engine of the mixer immediately after stopping, then the cooling system and lubricating oil supply will be provided It will also stop, which will damage the bearing of the mixer. Therefore, it is recommended to let the engine of the mixer run for 2-3 minutes before the engine is turned off, so that the turbocharger has enough time to cool down. However, the turbocharger can not idle for a long time, otherwise the turbocharger of mixer truck will also cause poor lubrication due to low oil pressure. Generally, the idle time should not exceed 10 minutes.
三。机油。搅拌车涡轮增压器确实比较“娇气”,除了机油量比普通自然吸气发动机大一些外,对油品的要求也更高。因为搅拌车涡轮增压器的设计与自然吸气发动机不同,大部分量产车的涡轮都是采用浮动轴承,即完全靠机油来润滑,所以,选择优质的机油尤为重要,而劣质机油的粘稠度较高,流动性较差,无法较好地发挥作用。司机在这方面切勿因小失大,建议给搅拌车更换全合成机油,这种油品有良好的抗氧化性,抗磨性,耐高温性能,润滑和散热性更佳。
3. engine oil. The turbocharger of mixer truck is really more delicate. In addition to the larger oil quantity than the ordinary naturally aspirated engine, it also has higher requirements for oil. Because the turbocharger design of mixer truck is different from that of naturally aspirated engine, the turbine of most mass production vehicles adopts floating bearing, that is, it is completely lubricated by oil. Therefore, it is particularly important to select high-quality engine oil, while inferior oil has high viscosity and poor fluidity, so it can not play a good role. The driver should not lose a lot in this respect. It is suggested to replace the fully synthetic engine oil for the mixer. This kind of oil has good oxidation resistance, wear resistance, high temperature resistance, better lubrication and heat dissipation.
四、检查。应定时检查搅拌车涡轮增压器的密封环,因为这也是很重要的一个部分,因为如果密封环失效,那么废气会通过密封环进入搅拌车发动机润滑系统使机油变脏,从而使曲轴箱压力升高,造成搅拌车机油的过度消耗,产生“烧机油”的情况。另外,搅拌车涡轮增压器转子轴承精密度很高,维修及安装时的工作环境要求也很严格,因此当涡轮增压器出现故障或损坏时应到指定的维修站进行维修,而不能到街边店修理。
4、 Check. The sealing ring of turbocharger of mixer truck should be checked regularly, because this is also a very important part, because if the sealing ring fails, the waste gas will enter into the engine lubrication system of the mixer through the sealing ring, which will make the oil dirty, thus increasing the pressure of the crankcase, resulting in excessive consumption of the engine oil of the mixer, resulting in "engine oil burning". In addition, the rotor bearing precision of the mixer turbocharger is very high, and the working environment requirements for maintenance and installation are also very strict. Therefore, when the turbocharger fails or is damaged, it should be repaired at the designated maintenance station instead of the street shop.
