Fully automatic mixer trucks are commonly used in engineering and construction, making significant contributions to our modernization construction. Mixers are a type of specialized vehicle, and many of them come from Suizhou, Hubei, the "capital of specialized automobiles". They are composed of a specialized vehicle chassis and upper body. Although they are specialized vehicles, they also occasionally malfunction like other vehicles. So what are the common faults of mixer trucks?
For the malfunction of a fully automatic mixer truck, we must first understand the nature of the malfunction, and based on the age of the mixer truck, whether the malfunction has persisted for a long time or suddenly appeared; Whether the fault still exists when the vehicle is empty or overloaded; Whether there are differences in faults when the speed is different, all of these factors need to be considered.
It should be noted that the center of gravity of the tank body of the mixer truck is on the axis, and under normal conditions, the operation of the tank body is stable. However, if there is material accumulation or uneven operation, it will cause the center of gravity of the tank body to shift, and the tank body will shake during operation. The shaking fault caused by material accumulation is manifested in the following two aspects:
1. The shaking of the tank body shows periodic changes, and 2. The shaking of the tank body is irregular. At this time, check whether the oil in the tank is turbid, and whether there is damage to the gearbox that has caused the oil to mix with metal particles.
Specific fault analysis:
The hydraulic system itself produces sound when outputting power, especially during high-power output. Therefore, if there is regular noise from high-power output when the vehicle is empty, it should be ruled out that it is due to the accumulation of material in the tank body. During heavy loads, if the load exceeds the set value of the system overflow valve, the system will overflow, and at this time, the hydraulic system will produce a sharp howling sound, while the oil temperature will quickly rise, Generally, mechanical noise can occur as the engine speed increases.
If the mixer truck becomes weak during heavy loading, the filter element should be disassembled for inspection. If metal powder, copper foam, or even large metal objects are found inside the filter element, it can be concluded that the hydraulic pump or motor is worn.
In fact, many mixer truck faults can also be seen on the dashboard inside the driver's cab. As long as everyone pays more attention in daily life, discovers and handles faults early, they will not delay the mixer truck operation due to faults. Come to our website if you have any needs Consult!
