Does it matter where the ultrasonic transducers are mounted on the cleaner tub?
|
There is a bit of a discussion on some analog audio blogs and discussion groups about the 'perfect angle' at which the ultrasonic transducers should be mounted on the cleaner tub for best cleaning results.
Fact is that (for engineering reasons), transducers can only be mounted flat on the tub (they are usually expoxied to the outer surface of the tub). Practically all commercially available cleaner models have their transducers mounted on the bottom of the tub to ensure a homogeneous penetration of the fluid volume in the cleaner. Generally speaking, the direction of the sound waves has no significant influence on the cavitation that is generated in the tank. The impinging waves generate low and high pressure regions throughout the fluid in a standing wave pattern. In the low pressure regions evacuated micro bubbles are generated. These bubbles have a certain life time, during which they move randomly through the fluid volume. Surfaces present in the fluid (like your vinyls) encourage the premature cavitation of the bubbles causing them to collapse, while emitting a jet of high pressure fluid towards the surface. These microscopic jets represent the cleaning action 'blasting' dirt from the surface of your vinyl records. This means the direction of the cavitation jets is mainly defined by the immersed surfaces and not by the position or angle of the ultrasonic transducers. |
