The corrosion-resistant magnetic pump is commonly used in industrial production. What is the reason for the loud noise when the device is used after the user has selected the type? What are the ways to reduce noise? The noise of the water pump is mainly the aerodynamic noise produced by the gas / liquid in the transportation process, the structural noise caused by the vibration of the motor shell, the noise caused by the vibration of the machine base, and the noise of the motor. This peak noise level is mainly concentrated in the low octave band, about 100-450Hz. The sound source is attributed to steady-state noise when the pump room is running normally. Pipeline noise refers to the noise caused by the flow of water moving in the pipeline. In addition, the cavitation phenomenon of the pump and the water hammer phenomenon of stopping the pump can also produce instantaneous noise. The noise generated by the water supply pipeline is affected by the flow rate and pressure.
The noise produced by the whole set of equipment in the pump room is mainly mechanical noise. Now the method of managing noise in acoustic principle is the transmission way of controlling noise, which mainly includes sound insulation, sound absorption, noise elimination and so on. Sound insulation is the use of sound insulation structure to separate the sound source from the receiving point; sound absorption is the use of sound absorption structure or sound absorption material to reduce noise; noise suppression is the use of impedance, resistance, porous dispersion and other principles to reduce noise value. Noise control methods should be based on acoustic principles and make full use of the environment and conditions of the place as much as possible.
Second, according to the environment of the pump room, close the sound source of the intight pump room for sound insulation treatment, take sound absorption and sound insulation treatment for the noise room produced by the pump room, and do sound insulation treatment for doors and windows, and so on. As the working principle and structure of different manufacturers and types of pumps are different, the site investigation and analysis of noise sources are very important for the design of sound insulation and noise reduction plan of pump room and the selection of materials.
