4. Troubleshooting
Only trained personnel are allowed into the inside of the machine.
4.1. GENERAL
This section contains detailed information for locating and correcting malfunctions. The
following steps provide an effective approach to the use of this information in
conjunction with other areas of the manual. If possible, consult with the operator who
used the Cleaner last. Find out what happened just before the trouble started and
indicated that a problem existed. Check to be sure that the system has the minimum
specified level of water in the cleaning tank and that the system has power prior to
troubleshooting.
4.2. PRINCIPLES OF OPERATION
Ultrasonic cleaning systems employ high frequency, mechanical vibrations transmitted
into and through a suitable cleaning liquid where the cleaning action takes place. High
frequency or ultrasonic vibrations are similar to audible sound, but the frequencies used
are generally above a level that can be heard (>18 kHz). Since sound is a compression
wave, the action of this high frequency energy in a liquid may be considered as the
rapid generation and violent collapse of minute bubbles. Countless small but intense
impacts erode surface soil from immersed parts. This action (cavitation) wears away
surface contamination...it does not "shake off the dirt".
An ultrasonic cleaning system consists of the following components:
1. An ultrasonic generator capable of producing high frequency electrical energy.
Ultrasonic Power Corporation utilizes our 5300 series generator.
2. Vibra-bar
®
transducer technology to convert electrical energy received from the
generator into mechanical energy.
a. Transducers fall into two main classes: Piezoelectric (electrostrictive) and
magnetostrictive. In the first instance, a material changes dimensions in the
presence of an electric field is utilized; in the second instance, the material is
influenced by a magnetic field (causes it to vibrate). Ultrasonic Power
Corporation uses the Piezoelectric (electrostrictive) transducers with its
generators.
3. A tank to contain the cleaning liquid (water-detergent mix) and into which the
mechanical (ultrasonic) energy is transmitted by the transducers.
a. Use of a suitable detergent is important because the liquid that transmits the
energy from the transducers also participates in the cleaning process: (1) the
mechanical action (cavitation), and (2) by solvent action, physical wetting or
chemical attack on surface soil.
4. The Heater pads are affixed to the sides of the tank. The heater controls are located
on the control panel.
