Electromagnetic sensor is a kind of used to control the equipment, in the process of using one of the most prominent problem is that there will be noise, to eliminate the noise will have to take certain measures to deal with.
1. Eliminate the noise generated during the cavitation process.
The sensor makes noise when used, one of which is due to cavitation, which is the main source of fluid power noise.
During cavitation, due to the rupture of the bubble, there will be a strong impact, and there will be strong turbulence in some parts, and the cavitation noise will occur.
The frequency range of such noise is wide, and the noise produced is very similar to the sound produced by the sand in the fluid.
2. The avoidance of resonance can also effectively eliminate noise.
If the sensor is resonant, because of the superposition of the energy, the noise will be very strong.
Sometimes the vibration is very strong, but the noise is general, sometimes the vibration is general, but the noise produced is very strong;
In some cases, vibration and noise are strong.
This noise is mainly from the resonant chamber, avoiding the resonance of the situation, the noise is not natural.
3. The pipe wall can be used with thick pipe wall.
If the wall is thinner, the noise will be more serious, and the thick wall tube can effectively reduce the noise.
If the wall is thicker, the effect of noise elimination will be more obvious.
4. Series throttling method is adopted.
In places where the sensor pressure is high, a series throttling method can be adopted, which is mainly to distribute the pressure to other parts.
In order to make the efficiency of the diffuser is more obvious, must according to the actual situation of installation for the diffuser design, make the valve and noise is generated by diffuser at the same level of noise.
5. Reduce noise by series muffler.
This method is suitable for use in some aerodynamic noise, it is very obvious to the noise and the noise level in the fluid which is transmitted to the solid boundary layer.
This method is the most obvious when some mass flow is high or the pressure drop ratio is higher before and after the solenoid valve, and the cost is not very high.
It is obvious that the absorption type series muffler method is used to reduce the noise effect, but the economic limit is basically attenuated to about 25 decibels.
