如今施工重新开工，搅拌车也开始工作，要注意使用起来比较麻烦，但是在高温状态下防护技术的安全使用我们应该做好哪些呢？这不仅可以实现安全操作，还可以延长搅拌车的使用寿命。

Now the construction starts again, and the mixer truck also starts to work. It should be noted that it is troublesome to use it, but what should we do well in the safe use of protective technology under high temperature? This can not only achieve safe operation, but also extend the service life of the mixer truck.

进入高温后，有针对性地对润滑系统各部件进行性能测试，使油压表和变速箱压力表指示准确。对变速箱、变桨器和驱动桥的油液进行系统检查，从油液质量到油量，保持油液清洁。

After entering the high temperature, carry out targeted performance tests on all components of the lubrication system to make the oil pressure gauge and transmission pressure gauge indicate accurately. Carry out systematic inspection on the oil of transmission, pitch and drive axle, and keep the oil clean from oil quality to oil quantity.

定期检查整机制动性能，以便尽快发现和排除制动系统故障，降低事故风险。如果长时间使用刹车，刹车毂和刹车片的温度会过高，刹车性能会降低。但切勿让刹车被迫用冷水冷却。

Regularly check the braking performance of the whole machine, so as to find and eliminate the faults of the braking system as soon as possible and reduce the risk of accidents. If the brake is used for a long time, the temperature of the brake hub and brake pad will be too high and the braking performance will be reduced. However, do not force the brake to be cooled with cold water.

检查水泵、风扇传动皮带。皮带长时间使用后，皮带会疲劳变形，降低冷却效果。更换皮带时，要注意型号和长度，正确调整松紧度。检查水箱的连接软管。水箱软管的耐油性比较差，容易过早损坏，从而影响供水，导致发动机温度升高过高。检查有无裂纹和渗漏，并及时清除。同时要保持足够的冷却水量，如发现不足应及时补充。

Check the water pump and fan drive belt. After long-term use, the belt will be fatigued and deformed, reducing the cooling effect. When replacing the belt, pay attention to the model and length, and correctly adjust the tightness. Check the connecting hose of the water tank. The oil resistance of the water tank hose is relatively poor, which is easy to be damaged early, thus affecting the water supply and causing the engine temperature to rise too high. Check for cracks and leaks and remove them in time. At the same time, sufficient cooling water should be maintained, and if it is found to be insufficient, it should be supplemented in time.

对自动上料搅拌车发动机也是要十分注意的，温度的升高会使发动机过热，因此要对发动机的冷却系统及时的检查和保养，比如及时的给水箱加水，清理散热器上的灰尘等，当水温超过100度时，应在阴凉处停车降温，让发动机怠速运转，掀起发动机罩散热。

We should also pay great attention to the engine of the automatic feeding mixer truck. The increase of temperature will overheat the engine, so we should check and maintain the engine cooling system in time, such as adding water to the water tank in time, cleaning the dust on the radiator, etc. when the water temperature exceeds 100 ℃, we should stop in the shade to cool down, let the engine idle, and lift up the hood to dissipate heat.

温度的升高会加速混凝土的凝结，因此在搅拌车行驶途中，搅拌筒一定不能停转，搅拌筒内混凝土中的水分也会蒸发，所以要适当的给混凝土加水，保证它的配比结构不变。

The rise of temperature will accelerate the setting of concrete. Therefore, during the driving of the mixer truck, the mixing drum must not stop running, and the water in the concrete in the mixing drum will also evaporate. Therefore, it is necessary to add water to the concrete appropriately to ensure that its proportioning structure remains unchanged.

气温的升高还会加速燃油的蒸发，因此容易在油路中造成气阻，那么我们就必须及时清洗燃油滤清器，以保证油路畅通。在行车途中一旦燃油系统发生气阻，应立即停车降温，并扳动手油泵使油路中充溢燃油。

The rise of temperature will also accelerate the evaporation of fuel, so it is easy to cause air resistance in the oil circuit, so we must clean the fuel filter in time to ensure that the oil circuit is unblocked. In case of air blockage in the fuel system during driving, stop immediately to cool down, and turn the hand pump to fill the oil circuit with fuel.
