The exhaust noise generated by the wheel loader spare parts is mainly the total noise radiated by the exhaust system. It includes three aspects, one is the radiation noise of the pipe wall, one is the radiation noise of the muffler wall, and the other is the tail pipe outlet. Initial radiated noise.
However, the reason for the noise is that during the operation of the loaded diesel engine, the airflow is unstable at the position of the exhaust valve, and the airflow is transmitted to the outlet of the exhaust system through the pressure fluctuation under the pressure fluctuation. At the outlet of the tail pipe, the speed is connected. Fluctuations can produce irregular noise, and it can be easily understood that the instability of the airflow in the exhaust system can cause exhaust noise.
The above is an introduction to the factors that cause the exhaust noise generated by the loader. I hope the above introduction is helpful to everyone. The following are instructions for using loader accessories during break-in:
1. Add lubricating oil during the running-in period: adding lubricating oil regularly can ensure that the degree of wear is reduced to a lower limit, and can also reduce the noise of the machine during operation.
2. Avoid overload during running-in: during running-in it is easy to cause parts and parts to wear faster, so after understanding it should be avoided as much as possible.
3. During the running-in period, the loader parts should be checked frequently: due to the effects of alternating loads (such as impact and vibration) and impact forces, the loader parts can easily make the originals tight at the initial stage of use. Heat and deformation, and excessive wear. Solid parts are loose, so check the loader parts frequently.
