The mixer truck is generally used to transport concrete to the construction site. The housing industry is very hot, so the construction site is very busy. The Zhongke Jufeng mixer truck is also nonstop. The hydraulic system of the mixer truck is frequently used. Many drivers report that the temperature of the hydraulic system of the mixer truck is too high. Then how can I deal with these problems? First of all, we need to know what the reason is, so that we can Can solve the problem fundamentally.

　　厂家的技术人员告诉我们，造成液压系统高温的原因有5个:

　　The technicians of Zhongke Jufeng factory told us that there are five reasons for the high temperature of the hydraulic system:

　　1.严重泄漏的液压系统,如果溢流阀设定压力过高,过多的运动部件的磨损会使密封间隙增加,密封装置损坏,油粘度太低,会导致泄漏增加,找到问题的原因。

　　1. For the hydraulic system with serious leakage, if the set pressure of the relief valve is too high, the wear of too many moving parts will increase the sealing clearance, damage the sealing device, and low oil viscosity, which will lead to the increase of leakage. Find out the reason to solve the problem.

　　2.液压系统散热不良。如油箱散热面积不足，油箱油位过低。

　　2. Poor heat dissipation of hydraulic system. If the heat dissipation area of the oil tank is insufficient, the oil level of the oil tank is too low.

　　3.油的粘度太大，也会造成水力损失太大。

　　3. The viscosity of oil is too large, which will cause too much hydraulic loss.

　　4.卸荷回路的液压系统,当水泥自动搅拌车系统卸载循环工作不良或没有卸货,混合器系统不需要强调,和石油仍在阀设置溢流罐的工作压力下,或在卸货压力高的意思是回油,这个时候应该仔细检查正常卸载电路工作系统,如果卸油方式被污垢,或电气系统故障,由于电磁阀卸荷效果不能工作，应及时采取措施加以排除。

　　4. For the hydraulic system of the unloading circuit, when the unloading cycle of the concrete mixer system is poor or there is no unloading, the mixer system does not need to emphasize, and the oil is still under the working pressure of the overflow tank set by the safety valve, or the unloading pressure is high, which means oil return. At this time, the normal unloading circuit working system should be carefully checked, if the unloading mode is dirty, or the electrical system fails, As the unloading effect of the solenoid valve cannot work, measures should be taken to eliminate it in time.

　　5.如果上述故障排除后,液压系统仍然存在高温的问题,有可能是由于直接影响油温升高速度控制方法,系统压力、液压缸、泵和电机的效率,额定流量的直径的各种阀门、管道、油箱体积,在液压和卸货的问题处理不当造成的,应该结合实际,具体分析,得出正确的结论。

　　5. If the problem of high temperature still exists in the hydraulic system after the above troubleshooting, it may be caused by the improper handling of various valves, pipes and tank volumes that directly affect the speed control method of oil temperature rise, the system pressure, the efficiency of hydraulic cylinders, pumps and motors, the diameter of rated flow, and the problems of hydraulic pressure and unloading, it should be combined with the actual situation and analyzed in detail to draw correct conclusions.

　　总之，无论发生什么样的混车故障，一定要冷静，找到故障的根源，这样才能迅速问题!

　　In a word, no matter what kind of mixed vehicle fault happens, we must be calm and find the root cause of the fault first, so as to solve the problem quickly!
