An ultrasonic cleaner is a device that uses ultrasound and an appropriate cleaning solvent to clean delicate items.
What is an ultrasonic Cleaner?
An ultrasonic cleaner is a cleaning bath that uses ultrasound waves (frequencies in the range of 20-400 kg Hz).
Ultrasonic Cleaners are used to clean metal, plastic, glass, ceramic dirt, grease oil and more,
Ultrasonic cleaning saves the need for manual cleaning, shortens cleaning time and more
Ultrasonic Cleaners are used in:
Machining, for cleaning grads, oil and grease. Automotive, aviation, shipping, parts cleaning, Cleaning watches and jewelry, Dentists, In the field of medical equipment and more.
Advantages of using an ultrasonic Cleaner
- Cleans a wide range of contaminants and bacteria
- Quality cleaning: Ultrasonic cleaning removes the dirt and the smallest particles.
-Professional: The cleaning operation works professionally and does not cause damage to the device if you work according to the manufacturer's instructions
-Saves time: No need to mess with it during operation
- Easy to operate
-Cleaning in the most difficult places to clean
Contaminants and bacteria are eliminated using an ultrasonic cleaner in an ultrasonically activated liquid with the use of high-frequency, high-intensity sound waves in a liquid.
The cavitation of solution molecules is caused by high-frequency sound waves, usually, around 40 kHz. But it can reach different levels of kHz
Full information on ultrasonic cleaners
Cavitation
The bubbles of cavitation develop when there is a void/ cavity formed by the sonic energy in a liquid solution of water or solvent, which becomes trapped as a bubble. Contaminants that are stuck to surfaces are displaced as these small bubbles rupture with force. Ultrasonic cleaning equipment uses microscopic bubble implosions to make such surfaces clean.
A guide to ultrasonic cleaning and ultrasonic cleaning devices
Glass, metals, ceramics, hard plastics, etc. constitute the materials that are capable of being cleaned by the process of ultrasonic cleaning. Dust, dirt, oil, grease, etc. can be cleaned by ultrasonic cleaning. Such a type of cleaning is very effective in removing impurities that cling to complicated goods that have recesses, blind holes, and fissures. Aqueous or solvent-based fluids can be utilized in industrial ultrasonic cleaning systems. For the reduction of surface tension and promotion of cavitation, surfactants or wetting agents are used in both types of cleaning solutions. Medical sterilization is usually performed after ultrasonic cleaning as the ultrasonic cleaning does not sterilize goods on its own.
Uses
Cleaning effectiveness is often limited with aqueous cleaning solutions, although they are better for the environment than solvent ones. Medical and surgical instruments are excellent examples of ultrasonic cleaning. Other industries include aerospace, dental, automotive, electronics, jewelry, etc.
Ultrasonic cleaning periods vary depending on the material and soil. Usually, the period is carried out for 3 to 6 minutes. Higher heat helps loosen dirt and chemical bonds faster, so most industrial Temperatures between 135 and 150 degrees Fahrenheit are used by most industrial parts cleaners because higher heat helps in the dissolution of dirt and chemical bonding faster.
Principle of operation
For best performance, some applications demand a lower or higher frequency while the most widely applied ultrasonic frequency for ultrasonic cleaning is 40 kHz. A higher frequency allows for the cleaning of more intricate detail. Larger and extremely filthy goods make usage of a frequency of 20 kHz, producing larger, stronger bubbles for cleaning but fewer bubbles every second. On the other hand, 200 kHz of frequencies are needed by some very small yet sensitive goods for ultrasonic cleaning.
components of an ultrasonic cleaning machine
Ultrasonic generator - AC electrical energy into ultrasonic frequency is converted through it. An ultrasonic generator is a device that produces ultrasonic waves. High-voltage electrical pulses are sent by the ultrasonic generator to the transducer. Electrical energy suitable for activating an ultrasonic transducer is converted from AC electrical energy.
Ultrasonic transducer - The ultrasonic electrical signal is converted to mechanical energy by the transducer. The ultrasonic transducer, often known as ultrasonic vibrations, is a device that produces sound above the audible range for humans that typically starts at 20 kHz. An active element, a radiating plate, and a backing make up the parts of an ultrasonic transducer. The backing of an ultrasonic transducer does the work of absorption of the energy that is radiated from the back of the piezoelectric crystal. Piezoelectric crystals are often used as the active element in a lot of ultrasonic cleaners. The piezoelectric phenomenon, in which crystals change size and form when electrical energy is applied, converts electrical energy to ultrasonic energy in the piezoelectric crystal.
Ultrasonic tank - The cleaning fluid and the objects to be cleaned are kept in this tank.
High-quality ultrasonic cleaners include:
- Stainless steel is made up of thick gauge.
- Generators which can self-tune and are square-wave.
- Transducers of piezoelectric crystals that are made up of high quality.
- Properly powered ultrasonic transducers.
