Guyson to show advanced ultrasonics

Tag: 1000W Generator

Numerous productivity and performance improvements feature the Kerry ultrasonic Primewave generator to be shown at MACH 2008 by Guyson International.

Guyson International will be introducing, for the first time in the UK, their all new flexible Kerry ultrasonic Primewave generator at the UK's MACH 2008 machine tool exhibition Guyson has incorporated numerous productivity and performance improvements, which will be available on all larger Guyson 'Kerry Ultrasonic' systems with integrated generators as well as in a host of OEM products OEM products include generator and submersible transducer sets, suitable for retrofit into pre- and post-cleaning tanks or for incorporation into new process lines.

The Primewave generator has two boards that produce up to 1000W owhen running at full power.

They will deliver a real 1000W output and not simply a nominal peak figure.

For larger ultrasonic tank systems this equates to fewer generators being required and real savings to be made, said Guyson.

* Flexible working - flexibility is one of the core Primewave strengths, said Guyson.

The new Kerry generator can operate in a variety of ultrasonic applications, in aqueous, solvent or viscous liquids.

It can also be customised by the operator to produce the quality of ultrasonic activity required, as dictated by the component complexity or by the substrate.

The Primewave generator can precisely control the ramp-up of power delivery so it can deliver a surge of power to 'jump start' cavitation in viscous liquids.

It can also feed in power incrementally to obviate damage to delicate items such as electronic circuits.

The new Primewave generator is proven to deliver a very robust cavitation.

'Cavitation' is where millions of miniscule cleaning bubbles are generated by alternating pressure waves created in the wash solution.

These waves create the cavitational bubbles which grow and then implode when at an optimum size, producing an extremely high energy scrubbing action that imparts the cleaning.

Typically, lower frequencies (e g, 25kHz) produce a larger cavitational bubble that delivers more energy and harsher cleaning action.

Higher frequencies (e g, 200kHz) produce a smaller cavitational bubble, which is better for internal cleaning of blind holes or more delicate cleaning for applications such as electronics.

Primewave has the power to perform even with cooler tanks and non-degassed solutions and proves far less susceptible to 'stalling' when baskets of components are loaded into the solution.

Primewave with its exclusive Primewaving technology is proven in foil tests to deliver superior, and faster cleaning compared to previous systems.

* Homogeneous cleaning - single frequency generators produce a uniform band of energy equidistant from the transducers, which are generally bonded to the underside of the tank, producing what is called 'standing' wave bands.

This uniform wave of energy is caused by the unvarying frequency or 'note' created and can prove inefficient at cleaning, Primewaving has the ability to produce more of a 'harmony'.

It does this partly by increasing the effective width and quantity of the pressure wave bands, so reducing 'dead' zones and hot spots in the tank solutions and producing a more homogenous cleaning action across the entire tank.

Primewave can also be used to power the two separate stages of a two stage cleaning machine, like the Kerry Microsolve, at different frequencies.

For example, stage one could run 38kHz and stage two 70kHz for final cleaning or rinsing.

The new generator can be cased in industry standard 19in rack mounted electronic enclosures and the individual internal boards are hot pluggable.

This allows the generator boards to be removed from the enclosure and a replacement board inserted within minutes.

Using the standard 19in rack mounted design also allows the generators to be easily and cost effectively configured in multiples for use in higher power applications.

The new system also features separate matching board PCB components, which are directly linked to the specific tank transducers so that new boards can be easily tuned and do not require tricky matching set-up procedures.

All of these features, said Guyson to manufacturingtalk, lead to a minimal downtime for maintenance.

They provide mission critical or very remote site applications (such as oil rigs) the ability to easily replace a spare board and maintain production without waiting for service call out visits.

In terms of process control the new unit provides tight regulation of output power from less than 20W to the maximum 1kW from each generator.

An easy to read front panel display provides instant at a glance power monitoring, which can also be easily verified by plugging in an external analyser directly into the front mounted socket.
