What are the main reasons for the noise generated by small loader accessories?

The exhaust noise generated by small loader accessories is mainly the total noise radiated by the exhaust system, which includes three aspects: one is the radiated noise of pipe wall, one is the radiated noise of muffler wall, and the other is the starting radiated noise of tailpipe outlet.
However, the reason for the noise is that during the operation of the loader diesel engine, the gas flow is unstable at the exhaust valve, and the air flow is transmitted to the outlet of the exhaust system in the form of pressure fluctuation. At the outlet of the tailpipe, the speed fluctuation produces irregular noise. It can be simply understood that the instability of the air flow in the exhaust system causes the exhaust noise
The above is the introduction to the factors causing exhaust noise of loader. I hope the above introduction can be helpful to you Here are the precautions for the use of loader accessories during running in:

1. Add lubricating oil frequently during the running in period: lubricating oil can ensure that the degree of wear is minimized, and the lubricating oil can also reduce the sound of the machine during operation
2. Avoid overload operation during the running in period: it is easy to cause rapid wear of parts during the running in period, so overload operation should be avoided as far as possible after knowledge
3. During the running in period, the loader accessories should be checked frequently: at the initial stage of use, due to the impact, vibration and other alternating loads, as well as the influence of heating, deformation and other factors, coupled with the rapid wear and other reasons, the originally fastened parts are easy to loosen, so the loader accessories should be checked frequently
