Teach you how to solve the noise problem of auto parts ultrasonic cleaning machine , do you want to learn?
In fact, the exact definition of ultrasound or ultrasound is an inaudible noise, or a noise beyond the audible range. Auto parts ultrasonic cleaners are usually fixed at 20kHz or higher. Typical ultrasonic frequencies range from 25kHz (used to clean heavily contaminated welds, castings and assembly parts) to 130kHz (used to clean highly polished surfaces or fragile parts very finely).
In fact, the ultrasonic cleaning of auto parts makes noise. What you hear is not the ultrasonic vibration of the converter of the auto parts ultrasonic cleaning machine, but the so-called random harmonics generated by the cleaning device (including the washing tank, the washing tank housing, the cover, and the parts to be cleaned). A tiny harmonic can be defined as a sonic thymus, where the frequency is part of the original ultrasound frequency.
Cavitation (the explosion of small bubbles used for cleaning) is not as pronounced as caused by low-harmonic vibrations, but it produces an audible "hissing" sound. To teach you how to solve the noise problem of auto parts ultrasonic cleaning machine, you have to learn.
At lower frequencies (such as 25kHz), the noise level generated by the operation of the auto parts ultrasonic cleaner will be more obvious, but at frequencies above 37khz and 45kHz, the noise level will be significantly reduced. Repeated exposure to the harmonic noise emitted by the auto parts ultrasonic cleaning machine will be very annoying and affect the work efficiency of personnel. There are many ways to deal with the noise of an ultrasonic cleaning machine for auto parts. Teach you how to solve the noise problem of auto parts ultrasonic cleaning machine, you have to learn.
1. Protect your ears. The advantage of these is to mute the harmonics of the miners, which also prevents employees from listening to instructions. Don't comment on piercing employees. This is a human resources issue.
2. Optimize the shell of the ultrasonic cleaning machine for auto parts. High-frequency noise has strong directivity and short wavelength, so it is easily absorbed by acoustic materials reflecting obstacles. The casing can contain a lid, some of which are equipped with an ultrasonic cleaner for auto parts or can be ordered as an option. The heat shield can improve the noise reduction effect. If the cleaning solution specifies a high temperature, all covers have the advantage of reducing evaporation and heat loss of the cleaning solution.
3. When cleaning agents are not used, turning off the auto parts ultrasonic cleaning machine is a good way to deal with small harmonics and save energy.
4. Purchase specially processed auto parts ultrasonic cleaning machine noise reduction cleaning equipment, such as Fuyang silent ultrasonic cleaning machine series.
