The ultrasonic frequency waves, which range from 20kHw to 200 kHz within the machine, create a bubble in the water-based solvent. When the bubble explodes when it comes in contact with the surface of objects, it turns into mechanical energy in the form of shock waves. Transducer and generator are the two key components of the ultrasonic cleaner. The electrical energy is converted into ultrasonic waves by the generator, and the transducer converts the oscillating current into mechanical vibration. There are two types of the transducer; piezoelectric or magnetostrictive.
Advantages
- Ultrasonic cleaning machine is widely used in many industries to remove unnecessary residues and detrimental contamination from their equipment. With the improvement in technology, the machines are becoming safer, cost-effective, and reasonable. Ultrasonic machines have the edge over cleaning methods like a hand or machine washing. Solvents used in other types of cleaning are acid-based and have toxic elements in them. Compounds like chlorinated hydrocarbons and esters are highly toxic and pollute groundwater when it sips in. The vapors which come out from these detrimental chemicals are also toxic, and the employees need to wear protective masks to protect themselves from these hazardous gas. Solvents used in the ultrasonic cleaner are biodegradable and safe as they are water-based.
- Not only these solvents are eco-friendly and biodegradable and do not emit harmful fumes; it is also safe for workers. The worker need not touch those objects with detrimental contamination and risk to infection. Cleaning medical equipment like drill bits and scalpels by hand can expose the person to probable biohazard if he accidentally gets pierce in the skin. In this cleaning method, the worker needs to submerge the instruments in the tank filled with solvents and switch on the machine.
- Delicate and precision equipment need a gentle yet thorough cleaning, toxic chemicals or harsh handling can damage the piece. The cavitation effect produced within the machine allows the mixture of water and solvent to reach inaccessible crevice and crack and clean the object from unwanted contamination without damaging the delicate equipment.
- Many government agencies and offices have started using these machines. Householders use this machine to clean their valuable, delicate jewelry and antique coins to get rid of dirt, grime, and skin oil. Automotive shops use ultrasonic machines to clean automotive parts and tools from lubricants, grease, metal strips, and other residues for optimal functioning of the vehicle. Law enforcement agencies like police and federal agents sterilize their weapons, handcuffs and other equipment with ultrasonic cleaners. The size of these machines varies from compact desktop to huge chambers used to clean long-barreled weapons like shotguns, rifles. There are customized solvents to remove specific contamination, while for regular use tap water, the minimum amount of detergent is sufficient enough.
Summing up
Ultrasonic cleaning machines are highly efficient and clean more thoroughly than hand or machine.
Based on cleaning systems. Less amount of water is needed in ultrasound cleaner than other cleaning methods, which saves precious water. These machines consume minimum power during operation, making them energy efficient and saving in the power bills.
