The cleaning load of your parts tank will determine the number and placement of the submersible transducers, which are available in custom sizes, wattage, and frequencies including 25 kHz, 40 kHz, 58 kHz, 132 kHz, 192 kHz, 470 kHz, and 1000 kHz as well as custom combinations including 2040 kHz and 58192 kHz.They can be mounted on either the sides or bottoms of the cleaning tanks, depending upon their geometry.You can also move our immersible transducers from tank to tank, or reposition them on tanks as required for special situations and needs.
Sonic Transducer Series Of CrestAnd you can rack-mount a series of Crest immersibles so that they can be installed andor removed as a group to speed up tank cleanings, inspections, and maintenance.By utilizing piezoelectric ultrasonic transducers these motors can be designed to be relatively efficient and simple, with few rotating parts and minimized maintenance over a wide range of operating conditions. Most common types of ultrasonic applications include motors, cleaning devices, and various sensors. Here we will discuss ultrasonic transducers used in motor and cleaning tools we have previously covered ultrasonic sensors in the Sensors section. Types of Motors and Basic Mechanics We will discuss two types of motors: linear and rotary. Both types utilize a repetitive motion generating small movements. The simplicity and high frequency capability of piezoelectric transducers are often a perfect solution for these applications requiring minimal movement. Piezoelectric crystals can be applied in two ways: they can either be used to generate the movement, or to generate friction. The latter type uses locking mechanisms, where the crystal can either be locked or free (to or from the surface being traversed). A crystal becomes locked by expanding and creating frictional force with the surface. Conversely, it becomes free by contracting and moving out of contact with the surface. This crystal generating movement utilizes the frictional force and expands to move across the surface. Three Piece Motors The most common type of motor (both linear and rotary) uses one rectangular crystal to generate movement and two crystals on either end to generate friction. When expanding, one crystal locks while the other frees up, causing the motor to generate motion away from the locked crystal. When the center piece contracts, a force is, again, exerted away from the first piece. One variation of such a motor is where one piece is always free and the other is always locked. It then contracts rapidly, generating enough force for the locked piece to slip towards the free piece slightly. Cleaning Mechanics Ultrasound cleaning utilizing piezoelectric transduction is a straightforward process. A vibratory transducer operating at ultrasonic frequencies in a fluid (normally water or a cleaning solvent) creates bubbles from the vibrations, exerting high amounts of force on molecules on the surface of the object being cleaned. This cleaning process generally lasts for less than twenty minutes. This method for cleaning is extremely volatile and effective, and is widely used by jewelers, fishermen, dentists, and electricians. Due to the extra force provided by the vibrations, potent chemicals or cleaning agents are either minimized or no longer required. Benefits of Piezoelectricity For motor applications, piezoelectric ceramic products shine in their precision. Since the individual movements are so small, it is easy for the motors to be controlled to the micrometer level.
