reading. Our products series are developing constantly and any technical change, we can adopt without other
advise.

General introduction

Ultrasonic cleaning machines, introducing foreign advanced technology and equipment, were developed by
technologists through many years of researches.
The ultrasonic cleaning machine made by our factory is widely used in fields like hospitals, pharmacies,
schools, scientific researches, petroleum, chemical industry, light industry, metallurgy, machines,
transportations, national defences etc. Currently it's an ideal, efficient and accurate cleaning equipment to
clean thoroughly the instrument, meter, electronic device, circuit board, magnetic material, galvanized parts,
hardware, optical lens, audio-frequency magnetic head, spinneret, latex mold, medical apparatus, glassware,
bijouterie, parts of a clock and watch, fine metal, bearing, nozzle, oil pump and parts in manufacturing
machine and some shape-complicated parts, especially the deep hole, blind hole and concave or convex
surfaces.

Working principle

The ultra-audio-frequency electric signal produced by the ultrasonic generator in a ultrasonic cleaning
machine is conversed to the mechanical vibration with the same frequency through the piezoelectric inverse-
transforming effect of the transducer, and then it will radiate forward intensively in the cleaning solution in
the form of ultra-audio-frequency longitudinal wave (The ultra-audio frequency longitudinal wave spreads
alternatively between zones of negative pressure and positive pressure), producing ten thousands of small
bubbles to explode in turn. It's these small bubbles which form and grow in the zone of negative pressure,
and explode instantaneously in the zone of positive pressure, to strike with high pressure the surface, gap, and
small local of a cavity to be washed, leading to peeling off of fouling quickly, thus the good cleaning and
purifying effect can be reached.

Safety instructions

1. Before using, please read the manual carefully.
2. Before using, make sure the ground connection should be OK.
3. No fire can be permitted in the circumstance.
4. When using the liquid which is easy to be fired, please take care of it.
5. Please don't let the temperature of liquid over 80°C, generally speaking, normal and middle temperature
is enough.
6. If no liquid in the tank, don't start the machine and heating, avoid the machine damaged under no-
loading condition.
7. You should use good-quality, big power plug, don't use bad quality plug, don't use this together with air
conditioner and electric heater, avoid the current too big.
8. Only personality can be permitted to use it.
9. Don't use big power unit to be working together with this machine, don't use this machine into the water to
working.
