The tank operation of the full-automatic feeding mixer is operated by hydraulic transmission. The hydraulic oil moves at a certain speed in the pipeline for a long time, which conflicts with the pipe wall. In addition to the resistance of various valves in the pipeline and the work of the oil pump, the hydraulic oil is compressed, which makes the hydraulic oil generate heat and the oil temperature rises. Hydraulic oil normal operation, there is a certain temperature is merit, but if beyond the temperature scale, not only will make the whole operation system unstable, but also will damage the seal and aggravate the oxidation and degeneration of hydraulic oil. The hydraulic oil heat dissipation system of small concrete mixer truck is generally composed of the following four parts, among which it is easy to have faults is used to maintain the stability of the whole circuit. Therefore, when presenting such problems, drivers of small concrete mixer should check whether it is stable and normal before troubleshooting other parts.

全自动上料搅拌车的热交换器相似水箱，液压油流过来降温。和发动机散热的原理相同，小型混凝土搅拌车运用液压油散热器来进行降温。热交换器（也能够叫做散热油箱）上装的电机驱动电扇进行强制的散热，让液压油保持在正常的作业规模。上面的机械式指针通过检测管路傍边的负压，假如呈现读数证明液压油滤清器或许呈现阻塞，刚开始呈现的时分只需要拔掉上面的橡胶塞让指针归零，假如后边还呈现读数且拔掉橡胶塞之后还不了的话，就需要替换液压油滤芯了。

The heat exchanger of the full-automatic feeding mixer is similar to the water tank, and the hydraulic oil flows to cool the temperature. With the same principle of engine heat dissipation, small concrete mixer truck uses hydraulic oil radiator to cool down. The heat exchanger (also known as the radiator tank) is equipped with a motor to drive the electric fan for forced heat dissipation, so that the hydraulic oil can be kept at normal operation scale. The mechanical pointer above detects the negative pressure at the side of the pipeline. If the reading shows that the hydraulic oil filter may be blocked, it is only necessary to pull out the rubber plug on the top to let the pointer return to zero at the beginning of the display. If the reading at the back still shows and the solution can not be solved after pulling out the rubber plug, the hydraulic oil filter element needs to be replaced.
             

全自动上料搅拌车的电机驱动电扇，带走液压油热量。电机是整个散热体系傍边，然后注意要害的部件，散热作用的好与坏，和电机的转速以及作业的平稳状况有着直接的联系。它由衔接车辆电瓶的电控盒直接供电，用电力驱动电机高速作业，来带走热交换器傍边的热量，给液压油降温。

The electric fan driven by the motor of the fully automatic feeding mixer can take away the heat of hydraulic oil. The motor is the whole heat dissipation system side, and then pay attention to the key parts, the heat dissipation effect is good or bad, and the speed of the motor and the stability of the operation has a direct connection. It is directly powered by the electric control box which connects the vehicle battery, and uses the electric drive motor to work at high speed to take away the heat near the heat exchanger and cool the hydraulic oil.

小型混凝土搅拌车温度传感器，检测液压油温度。安装在热交换器进油管上的传感器，用来检测进入热交换器中液压油的温度，它是在扫除稳妥毛病之后二个来扫除的毛病点。

Small concrete mixer temperature sensor to detect the temperature of hydraulic oil. The sensor installed on the oil inlet pipe of the heat exchanger is used to detect the temperature of the hydraulic oil entering the heat exchanger. It is used to remove the two fault points after clearing the safe fault.

小型混凝土搅拌车操控盒是大脑，不让液压油高温。操控盒是整个散热体系傍边的大脑，相似于车辆的ECU，温度传感器传递过来的数据通过它的剖析，超越预订的温度值之后接通散热电机的电路，让电机作业来带走液压油中的温度。它的上面装有维护整个电路的稳妥，让操控盒不会容易损坏。

Small concrete mixer control box is the brain, not to let the hydraulic oil high temperature. The control box is the brain beside the whole cooling system, similar to the ECU of the vehicle. Through its analysis, the data transmitted by the temperature sensor exceeds the predetermined temperature value, and then the circuit of the heat dissipation motor is connected to let the motor work to take away the temperature in the hydraulic oil. It is installed on the top of the maintenance of the entire circuit, so that the control box will not be easy to damage.
