The small commercial concrete automatic mixer includes truck chassis, mixing drum, transmission system, water supply, full power output, front and rear bracket of mixing bucket, reducer, hydraulic transmission system, air supply / exhaust system and operating mechanism. Unlike large self-propelled vehicles, most of the four components required for this technology are imported.

該車有兩種類型的底盤：傳動系，液壓系統，框架，混合罐，給水和卸載裝置，供水系統和操作系統。混合罐的前端連接到減速器并連接到機架的前部。后端由兩個滾輪支撐，滾輪通過滾道連接到機架的后部。

There are two types of chassis: drive train, hydraulic system, frame, mixing tank, water supply and unloading device, water supply system and operation system. The front end of the mixing tank is connected to the reducer and to the front of the frame. The rear end is supported by two rollers, which are connected to the rear of the frame through the raceway.

高溫下小型商砼自動攪拌車的維護

Automatic maintenance of small concrete mixer under high temperature

1，防止發動機機體過熱：由于環境溫度較高，發動機容易過熱。有必要加強發動機冷卻系統的檢查和維護。這包括檢查水箱，恒溫器，水泵，風機等，并注意及時添加。注意冷卻水。當水溫超過100°C時，停在陰涼處冷卻，讓發動機怠速，并打開引擎蓋以幫助散熱。

1. Prevent engine body from overheating: due to high ambient temperature, the engine is easy to overheat. It is necessary to strengthen the inspection and maintenance of engine cooling system. This includes checking the water tank, thermostat, water pump, fan, etc., and paying attention to timely adding. Pay attention to the cooling water. When the water temperature exceeds 100 ° C, stop in the shade to cool, let the engine idle, and open the hood to help heat dissipation.

2，防止發動機爆燃：夏季氣溫高，有時超過35°C，而在這樣的季節，對于部分老化部件的汽車，所以要做好預防準備。

2. Prevent engine deflagration: the temperature is high in summer, sometimes exceeding 35 ° C. in such a season, for vehicles with some aging parts, it is necessary to prepare for prevention.

3，防止汽車油漆損壞：汽車油漆經過強烈陽光照射后，會老化，起皺，而普通美容打蠟可以起到一定的防曬效果，但因為任何車蠟都含有鉍成分，長時間紫外線照射會使油漆生銹留下一點黑點。汽車蠟本身不能提高硬度和抗紫外線效果，但它會因高溫而迅速失去。停車時，請注意將車停在陰涼處。

3. Prevent the damage of automobile paint: the automobile paint will be aged and wrinkled after being exposed to strong sunlight, while the ordinary beauty waxing can have a certain sun protection effect, but because any car wax contains bismuth, long-term ultraviolet radiation will make the paint rust and leave a little black spots. Car wax itself cannot improve the hardness and UV resistance, but it will lose rapidly due to high temperature. When parking, please park in the shade.

4，防止汽車輪胎爆裂：高溫時，更容易穿刺，當溫度過高時，輪胎容易變形，抗拉強度降低。作為輪胎本身，氣壓不是標準的，輪胎老化，性能減弱，或者輪胎在行駛過程中被卷成硬質金屬或其他硬物，這將導致汽車突然爆裂。

4. Prevent automobile tire burst: it is easier to puncture at high temperature. When the temperature is too high, the tire is easy to deform and the tensile strength is reduced. As the tire itself, the air pressure is not standard, the tire aging, performance degradation, or the tire is rolled into hard metal or other hard objects during driving, which will cause the car to burst suddenly.

5，防止發動機潤滑不良：當溫度高時，油的粘度降低，抗氧化性變差，導致潤滑不良。因此，請務必檢查油品質量并及時添加或更換。注意及時清潔機油濾清器和散熱器，確保油流暢通，散熱好，盡量避免發動機過載。

5. Prevent the engine from poor lubrication: when the temperature is high, the viscosity of the oil will be reduced, and the oxidation resistance will be poor, resulting in poor lubrication. Therefore, please check the quality of the oil and add or replace it in time. Pay attention to clean the oil filter and radiator in time to ensure smooth oil flow and good heat dissipation, and try to avoid engine overload.
