1. Prevent overheating of the concrete mixer engine body: due to the high ambient temperature, the engine is easy to overheat. It is necessary to strengthen the inspection and maintenance of the engine cooling system, including the inspection of water tank, thermostat, water pump, fan and other components, and pay attention to the timely filling of cooling water. When the water temperature exceeds 100 ℃, stop in a cool place to cool down, let the engine idle, and lift the engine cover of the concrete mixer to help dissipate heat.
2、防止混凝土搅拌机发动机爆燃:夏季气温较高,有时会超过35℃,而这样的季节,对于一些部件有所老化的汽车来说,发生自然爆燃等的概率也高出很多。所以要做好防范准备。
2. Prevention of engine deflagration of concrete mixer: the temperature is high in summer, sometimes exceeding 35 ℃. In this season, the probability of natural deflagration is also much higher for some aging vehicles. So we should be prepared.
3、防止车漆受损:车漆经过强烈的阳光曝晒,会发旧、起皱,而普通的美容打蜡虽然可以起到一定的预防暴晒效果,但由于任何车蜡都含有矽的成分,久经紫外线照射会锈蚀车漆,留下点点黑斑。车蜡本身起不到增强硬度作用,反而会因温度过高而很快流失,停车时要注意尽量把车停放在阴凉处。
3. To prevent damage to the car paint: the car paint will get old and wrinkled after being exposed to strong sunlight. Although ordinary beauty waxing can play a certain role in preventing exposure to the sun, because any car wax contains silicon, it will rust the car paint after a long time of ultraviolet radiation, leaving a few black spots. The car wax itself can not enhance the hardness, but will be quickly lost due to high temperature. When parking, pay attention to parking the car in a cool place as far as possible.
4、防止混凝土搅拌机车胎爆裂:气温高所以比较容易爆胎,温度过高时很容易使轮胎变形,抗拉力下降。而作为轮胎本身,气压不标准、轮胎老化、性能减弱,或者在行驶过程中轮胎轧到了坚硬的金属或其他硬物等情况,都会导致汽车突然间爆胎。
4. Prevent the tire of concrete mixer from bursting: the tire is easy to burst due to high temperature. When the temperature is too high, it is easy to deform the tire and reduce the tensile resistance. As for the tire itself, non-standard air pressure, tire aging, performance degradation, or hard metal or other hard objects rolled by the tire during driving will all lead to sudden tire burst.
5、防止混凝土搅拌机发动机润滑不良:温度高时,机油粘度下降造成润滑不良。所以要经常检查油量油质,并及时添加或更换。要注意及时清洗机油滤清器、散热器,保证机油通畅、散热良好,并尽量避免发动机超负荷工作。
5. Prevent poor lubrication of concrete mixer engine: when the temperature is high, the oil viscosity drops, resulting in poor lubrication. Therefore, the oil quantity and quality shall be checked frequently and added or replaced in time. Pay attention to timely clean the oil filter and radiator to ensure smooth oil and good heat dissipation, and try to avoid engine overload.
6、防止混凝土搅拌机刹车制动失灵:制动液在高温环境中更容易蒸发汽化,在制动管路中形成气阻,制动蹄片也容易烧蚀,造成制动失灵。所以要经常检查调整制动系统,下长坡途中应注意停车晾刹,保证制动性能良好。如果发现制动毂发烫,应停车降温,但不可浇泼冷水,以防制动毂破裂。
6. Prevent the brake failure of concrete mixer: the brake fluid is easier to evaporate in high temperature environment, forming air resistance in the brake pipeline, and the brake shoe is also easy to be ablated, resulting in brake failure. Therefore, the braking system should be checked and adjusted frequently. On the way down a long slope, attention should be paid to parking and braking to ensure good braking performance. If the brake hub is found to be hot, stop the vehicle to cool down, but do not pour cold water to prevent the brake hub from cracking.
