How to operate the ultrasonic cleaning machine safely?Date: 2022-09-02Number: 213
Safe operation of ultrasonic cleaning machines is a broad theme, not only to open the equipment and carry out the cleaning cycle. Good safety practices apply to ultrasonic cleaning machines of any size -- whether used in homes, research laboratories, or industrial plants.
By doing so, you are ensuring a smooth running experience, which is one of the most effective ways to remove contaminants from almost any product that can be safely immersed in a water-based biodegradable cleaning solution, or use a specially designed cleanser, a volatile cleaning solvent.
Good personal safety practices during ultrasonic cleaning
Ultrasonic cleaning is safe
These are not overly complicated. It is important, if not the most important, to remember that ultrasonic cleaning solutions can become hot due to cavitation. Continuous operation can raise the cleaning fluid temperature to 1750F or higher-even if the equipment is not equipped with heaters.
The recommended cleaning solution temperature is provided by the manufacturer and does not always require high temperatures. However, you should never reach into a running ultrasonic cleaning tank to disassemble and inspect parts. Not only are you at risk of Burns, but cavitation can also penetrate your skin. It's not good.
Hearing protection may also apply to good personal safety practices. Although ultrasonic frequencies are defined as sounds above the human auditory range, audible sounds are generated by cleaning tank walls and other sources of vibration.
At lower cleaning frequencies, such as 25 and 45 kHz, the potential for undesirable noise is increased. Over time, this can become tiresome to staff.
Good practice for safe operation of ultrasonic cleaning machines
You have invested in ultrasonic cleaning equipment. There are many steps you can take to safely operate this device and help extend its satisfactory life.
Provide reliable power supply
Ultrasonic cleaners use powerful sensors to convert electrical energy into sound. The cleaner is equipped with a three-hole earthing socket for the power supply and must be connected to a similar earthing socket.
It is also strongly recommended that ultrasonic cleaners have their own dedicated outlets, rather than sharing multiple outlets or circuits for high-power machines such as sterilizers, autoclaves or Air compressor. Circuit overload can cause circuit interruptions, which are undesirable under any circumstances.
SAFE operation of equipment
Other precautions can be taken to keep the equipment running at maximum efficiency.
One measure is not to place items directly on the bottom of the tank. Ultrasonic vibrations that create cavitation bubbles can also cause items in contact with the tank to vibrate, eventually causing wear that can penetrate the bottom of the tank. This invalidates the manufacturer's warranty.
Instead, items should be placed in a net-bottom basket or tray suspended above the bottom of the tank. Note that some large industrial ultrasonic cleaning machines may create ridges at the bottom of the tank to hold heavy components in place. Alternatively, the parts to be cleaned can be hung on an overhead shelf to prevent them from touching the bottom of the tank.
Maintaining appropriate levels of cleaning fluid is also important for the safety practice of ultrasonic equipment. These devices are designed for a specific volume (level) of cleaning solution. In many units, this is represented by a fill line.
Evaporation and efflux reduce the level. The manufacturer advises operators not to run equipment when the tank is less than 2/3 full. This is because low liquid levels can damage the generators and heaters in the equipment.
Special ultrasonic cleaning machine safety protection function
It is highly recommended to purchase an ultrasonic cleaning machine equipped with a timer. Some devices display settings and elapsed times and close at the end of the cycle. Others can run continuously with automatic shutdown for up to 12 hours.
If the user does not manually turn them off before leaving during the day or on the weekend, models that do not have automatic shutdown can become corrupted. If this occurs, the equipment may burn out and/or damage components left in the tank as a result of evaporation of the cleaning fluid.
Maintain how safe ultrasonic cleaning machines contribute to
Vibration from the Ultrasonic transducer creates wear points at the bottom of the tank, which over time develop into wear known as cavitation. This occurs even in tanks made of cavitation-resistant stainless steel. This erosion will require replacement of the water tank before the leak occurs.
