NOTICE:
Each individual will produce its own sound, which is also a sign that represents us. For machinery and equipment that has malfunctions, the noise under each malfunction can also be unique, so we can start by analyzing the noise, Solve the problem of tunnel mucking machine.
The noise on the tunnel mucking machine can be divided into three categories according to the mechanism it generates, namely aerodynamic noise, combustion noise and mechanical noise, while aerodynamic noise in the exhaust system is usually the main noise source. Generally speaking, If the exhaust noise of the diesel engine can be effectively reduced, the total noise level of the rock loader can be greatly reduced.
Under normal circumstances, the noise of an electric tunnel mucking machine increases linearly with the increase of its speed. Like a natural aspirated four-stroke rock loader, the noise increases by 30dB (A) for every 10 times the speed. A four-stroke supercharged rock loader For every 10-fold increase in speed, the noise increase is 40dB. If noise peaks appear during the increase, this is the problem in noise source identification. You can use 1 / 3-octave frequency spectrum analysis to initially identify the main noise components.
Every thing has its own unique characteristics, and noise has gradually become evidence to solve these problems. If our electric rock loading machine fails, you may try listening recognition method, I believe we can all do it of.
