The sound device is adopted to the size of the move of the operation of the belt and the quality inspection, stripping of belt even if there is a little damage, also an exception and irregular, and with the sound of the measuring device can distinguish.
Listening to the use of hearing to recognize irregular movements is a common method. For example, using an electronic stethoscope to find out that the abnormal noise of a part is often the method used by the experienced operator.
If the belt is in good condition, it will make a low noise. If a sharp hiss, squeak, and other irregular sounds are made, it often indicates that the belt is in a bad condition.
The squeaking noise may be caused by improper lubrication. Improper belt gaps also cause metal sounds. The concave of the concave track on the outer ring of the belt will cause vibration and make the sound of smooth and crisp. If the injury caused by the installation is also caused by the noise, the noise will be different from the speed of the belt.
If there is intermittent noise, the movement may be damaged. This sound occurs when the surface of the damaged surface is overpressed, and if there is a pollutant in the belt, it usually causes fizz. Severe conformable damage can result in irregular and loud noise.
The belt damage can be checked by hearing, but usually the belt must be replaced immediately. Therefore, better methods such as using electronic condition monitoring instruments. Use a stick more accurately than the old method to estimate the belt condition.
