A little common sense about ultrasonic cleaning of filters
Industrial companies need to ensure that their equipment is always operating at optimal levels to avoid affecting production time or quality. This means they need a way to remove all unwanted particles from the fluid flow before it enters other machines to maintain optimal performance standards.
The cleaning of the filter is essential for the removal of contaminants from the fluid before it is released into the downstream process. The use of ultrasonic cleaning can improve this process by ensuring that no harmful substances are left behind.
Ultrasonic cleaning uses 20-40 kHz of ultrasound to stir the cleaning fluid or the appropriate solvent to remove difficult to remove debris. Regular ultrasonic cleaning can extend the service life of equipment and optimize flow rate and performance.
Here, we discuss what an ultrasonic cleaner is, how it works, and why it is such an important part of the filtration systems of industrial companies.
What is ultrasonic cleaning of filters?
Ultrasonic cleaning can effectively remove hard-to-reach places of dirt particles, bacteria and sticky substances. Immersion filters are exposed to high-frequency sound waves, which can agitate the clean solution or solvent, resulting in cavitation of solution molecules. Cavitation bubbles are formed when acoustic energy creates voids or cavities. A large number of tiny cavitation bubbles form and get trapped in the cleaning solution. When these bubbles burst, debris and contaminants fall off the surface, creating clean filters and equipment.
How does ultrasonic cleaning work?
Ultrasonic cleaning is quite different from traditional cleaning methods because of its high cleaning ability. An object such as a filter is immersed in a water tank containing a liquid solution or cleaning solvent, and then a transducer is inserted. The transducer converts electrical energy into ultrasonic energy, producing sound waves and cavitation bubbles that accumulate over time. These bubbles implode in an effort to remove stickiness, dirt, grit, and impurities to achieve a thorough and effective cleaning.
What is cavitation?
Cavitation is the formation of many tiny bubbles or cavities in a liquid. These bubbles form when sound waves travel through a fluid. All these little bubbles are full of blanks. When cavitation bubbles burst or burst, impurities such as dirt, oil, debris and dirt will fall off, thus making the surface cleaner.
How long does it take to clean the filter with ultrasound?
The time required to complete the ultrasonic cleaning process depends on the size and cleanliness of the filter or object, but the average cleaning time can be between 3-10 minutes. Heating the solution can loosen dirt and chemical bonds, thus reducing cleaning time, so you can reduce cleaning time by heating it.
Ultrasonic cleaning applications
Ultrasonic cleaning is an effective way to reuse filters and keep them functional for long periods of time. Ultrasonic cleaning is a popular cleaning method in many industries such as factories, hospitals and other enterprises.
Effective removal of ultrasonic cleaning:
Oil and grease
Varnish and paint
Ultrasonic cleaning is effective in cleaning a wide range of filters, including:
What are the benefits of ultrasonic cleaning?
The benefits of ultrasonic cleaning are limitless. The following are some of the advantages of choosing ultrasonic cleaning based on user requirements:
Clean precision parts, will not be damaged by manual scrubbing
Clean every corner and corner, if manual or manual cleaning is not possible
There is no need for any irritant chemicals that may pose a danger to workers or the environment
Remove all types of contaminants, such as deep filters, from each filter
Restore the performance of the filter to 100%
It saves customers a lot of filter replacement costs
What is the relationship between frequency and ultrasonic cleaning?
The frequency of the generated ultrasound is measured in thousands of cycles per second. The frequency of 1 Hz represents one cycle of sound waves per second. Again, 20Hz will be 20 cycles and 100hz will be 100 cleaning cycles. Frequency is one of the main criteria for creating the correct bubble size, which will help clean items.
Higher ultrasonic frequencies tend to produce smaller bubbles that provide gentle scrubbing and cleaning.
In contrast, lower ultrasonic frequencies produce larger bubbles, resulting in a rougher cleaning.
On average, a frequency of 40 khz is sufficient to clean a filter or other application using ultrasonic cleaning.
How to select the appropriate frequency of ultrasonic cleaning?
The lower the frequency, the higher the cleaning intensity, and vice versa. Here's how different ultrasonic frequencies can be used for a variety of applications.
Large steel cutting tools
Stainless steel plate
Remove oil and metal filings from industrial machines
Remove soot from fire-damaged items
Remove biological contaminants from surgical tools
Clean Medical and optical instruments and components
Production of electronic products
Precision instruments or computer memory components
Ultrasonic cleaning basket
The basket supports the object by lifting it to a safe distance above the bottom of the tank. When an object is suspended in a basket, the cavitation bubbles disperse and evenly surround the object, making the cleaning process more efficient. The baskets, made of stainless steel and other non-porous materials, vary in size and allow items to be suspended at the correct depth for thorough cleaning.
Effective ultrasonic cleaning techniques
Here are some tips to make ultrasonic cleaning more effective:
Don't use boiled water.
Select a cleaning solution compatible with the object to be cleaned.
Solutions are used at warm temperatures, usually 50-65 ° C (122-149 ° F)
Do not fill the ultrasonic tank with HFE 7100.
How to choose the best ultrasonic cleaning service?
Precision Manufacturing and cleaning thoroughly cleans filters and parts by removing contaminants, improving efficiency and service life.
