Common failure analysis concrete truck mixer Tops

The car also has a life history of each car important new to old, from newborn to phase out, in the process, also like humans, various kinds of “illness”, then in the case of concrete truck mixers upload process to “illness”, we how to remedy it? Here are some common failure analysis coat, hoping to help the majority of riders and friends.
For faults, we must first pay attention to understand the nature of the fault appears: a sudden or gradual? Is a new car or fails to appear for a period of time? How long age of the vehicle? Are there laws fault? Overloading and empty car Symptom whether to change? High speed and whether there are differences in low speed fault phenomenon? For failure analysis of these factors have important reference value.

1, tanks shake: concrete truck mixer tank in the production process by machining to ensure that the center of gravity on the axis of the tank, so the tank during normal operation is stable, however, because the product material or material uneven operation It will lead to shift the focus of the tank, then the tank transport line will appear over the center of gravity of the upper and lower jitter at both points. Jitter performance since the product material failure caused by: 1, shake the tank operated with cyclical changes, 2, tanks shake no more than twice a week operation. Such a failure can be obtained by marking to identify the body. Of course,Does not rule out the processing tank causes tank eccentric, most OEMs have stringent requirements for the processing tank, tank eccentric possibility is very small, in addition, all the concrete mixer at the factory will be debugged, tanks eccentric mixer will not default, so for users, the possibility of the eccentric body is extremely low.
If the jitter is not the law, it is necessary to observe whether the muddy oil tank, running any abnormal noise, consider the possibility of air entrainment. Of course, do not forget to check the oil deceleration, gear exclude the possibility of damage, when mixed into chunks inside damaged gear reducer oil solution metal particles.
2, the noise: firstly, the hydraulic system itself will sound when the output power, particularly in the high-power output, so if there are empty regularity noise power output, the tank should be excluded from the possibility of serious product material. Noise is divided into two types: a dull roar, sharp
Clamor sounds. For the former, the air mixed with the reasons should be considered, whether the system is short of oil? Replacing the hydraulic oil filter and the last is when? System piping oil leaks? Clear whether oil tank? Clamor for sharp sounds, but also at high pressure overflow noise and mechanical causes noise, when overloaded, if the load is too large and exceeds the set value of the system relief valve, the system will overflow, then will produce a sharp clamor sounds, accompanied by the rapid increase in oil. Mechanical causes of noise often as the engine speed is increased to produce.
3, heavy weakness: weakness for overloading faults, we must first understand the age of the vehicle, and the reference vehicle maintenance conditions, in particular, should open the filter inspection, if found metal powder, copper and even chunks of metal foam, that is, within the filter It may conclude pump or motor wear.
