Ultrasound or ultrasound is a strict definition of sound that is inaudible or beyond the audible range. It is usually fixed above 20kHz. Common ultrasonic frequency ranges typically range from 25kHz(for cleaning heavily contaminated welded, cast, and assembled parts) to 130kHz(for very fine cleaning of highly polished surfaces or fragile parts). In fact, ultrasonic cleaners do produce sound. What is heard is not the ultrasonic vibration of the ultrasonic transducer of the cleaning machine, but rather the so-called sub-harmonics, which are established by the cleaning equipment (including the sink, the sink housing, the lid and the parts being cleaned). Sub-harmonics can be defined as sound waves whose frequency is a part of the original ultrasonic frequency. Cavitation (the implosion of tiny bubbles performing cleaning) also produces an audible "hissing" sound, although less pronounced than that caused by sub-harmonic vibrations. So how should we deal with the noise of ultrasonic cleaning machine? Noise levels generated by ultrasonic cleaner operation are more pronounced at lower frequencies (e.g. 25kHz) and significantly reduced at 37 and 45kHz or higher. Repeated exposure to subharmonic noise from ultrasonic cleaners can be annoying and affect personnel productivity.

There are several ways to deal with ultrasonic cleaner noise:

1. Ear protection. These have the advantage of silencing subharmonic sounds, but doing so also hampers the ability of employees to listen to instructions.

2. Optimize the equipment housing. High frequency noise is highly directional and related to short wavelength, which means that it is easily absorbed by obstacle reflective acoustic materials. Enclosures may include LIDS, some of which are equipped with ultrasonic cleaners or ordered as optional. The heat shield improves noise cancellation. All LIDS have the advantage of reducing evaporation and heat loss from cleaning solution when high temperatures are specified for the cleaning solution.

3. It is a good way to deal with sub-harmonics and save energy when not using cleaners.

4. Purchase silent ultrasonic cleaning machine.

What are the advantages of ultrasonic cleaning machine compared with traditional cleaning methods?

1. Technological advantages

Compared with other kinds of cleaning methods in the field of industrial cleaning, ultrasonic cleaning machine has been widely recognized for its excellent performance. Especially in professional households, integrated manufacturers, these manufacturers of high fixed production line, cleaning machine is very suitable for the use of these manufacturers. Therefore, ultrasonic cleaning machine has gradually replaced the traditional cleaning methods, such as immersion, pressure washing and other processes, become a common cleaning means.

2. High cleaning accuracy

Previous traditional cleaning means can only clean relatively easy to clean dirt molecules or devices with flat surfaces. And the professional ultrasonic cleaning machine can be competent for the precision cleaning of various products in the process of processing and production, all kinds of materials and equipment surface cleaning, can remove the device surface and hidden tiny dirt particles. This cleaning can make the internal components of the machine take on a new look and extend the life of the components.

3. Wide cleaning range

Traditional cleaning methods can be divided into physical cleaning and chemical cleaning, different from the traditional curing classification. Ultrasonic cleaning machine can borrow different cleaning solvents to achieve the cleaning effect of both. For example, ultrasonic cleaning machine cleaning can choose chemical solvents to remove rust on the surface of the object, scale, can also be directly water, through vibration to clean the object.

The above several aspects are the advantages of ultrasonic cleaning machine, and because there are many advantages, so it has been widely used in high-end industry development and application. So how to choose ultrasonic cleaning machine has become a big problem for enterprises, I think enterprises still want to find a responsible seller, in order to buy satisfactory ultrasonic cleaning machine.
