1、检查保险开关：
1. Check the safety switch:
搅拌车是通过液压传动系统来驱动罐体的，液压油散热系统中最容易出现故障的就是保险开关，因此在故障发生后，最好第一时间检查保险开关。
Mixer is driven by hydraulic transmission system, the most prone to failure in the hydraulic oil cooling system is the safety switch, so after the failure, it is best to check the safety switch at the first time.
2、检查驱动风扇：
2. Check the drive fan:
电机是整个散热系统中最为关键的部件，散热效果的好与坏，和电机的转速及运行的平稳状态有着直接的关系，它由连接车辆电瓶的电控盒直接供电，用电力驱动电机高速运转，来带走热交换器当中的额热量，给液压油降温。
The motor is the most critical component in the whole heat dissipation system. The good or bad heat dissipation effect is directly related to the speed of the motor and the stable running state. It is directly powered by the electric control box connected to the vehicle battery, and uses the electric power to drive the motor to run at high speed to take away the amount of heat from the heat exchanger and cool the hydraulic oil.
3、检查热交换器：

3. Check the heat exchanger:
搅拌车利用液压油散热器来进行降温。热交换器上装有电机驱动风扇进行散热，让液压油正常工作，上面的机械式指针通过检测管路当中的负压，如果出现读数证明液压油滤清器可能出现堵塞，刚开始出现的时候只需要拔掉上面的橡胶指针归零，如果后面还出现读书且拔掉橡胶塞之后还解决不了的话，就需要更换液压油滤芯了。
Mixer truck uses hydraulic oil radiator to cool down. The heat exchanger is equipped with a motor-driven fan to dissipate heat, so that the hydraulic oil can work normally. The mechanical pointer on the top detects the negative pressure in the pipeline. If the reading indicates that the hydraulic oil filter may be blocked, just pull out the rubber pointer to zero at the beginning. If there is still a reading behind and the problem can not be solved after pulling out the rubber plug, The hydraulic oil filter element needs to be replaced.
4、检查热传感器：
4. Check the thermal sensor:
温度传感器位于热交换器的进油管上，它的作用就是检测液压油的温度，搅拌车散热系统发生故障后，如果确认不是保险的问题，那就检查温度传感器。
The temperature sensor is located on the oil inlet pipe of the heat exchanger. Its function is to detect the temperature of the hydraulic oil. After the heat dissipation system of the mixer fails, if it is confirmed that it is not the insurance problem, check the temperature sensor.
5、检查散热器控制盒：
5. Check the radiator control box:
