Reducing Flow vs. Reducing Pressure – Which is it?

There is often a need in any system involving flow of a liquid to control the flow and/or pressure of that liquid.  Since the two are different and yet inter-dependant, it can be confusing when trying to determine if flow control or pressure control is the intended goal and how it will be best be accomplished.  Unfortunately, a wrong choice …

Ultrasonics – Pulse – More About Pulsed Ultrasonics

“Pulse” in ultrasonic terms simply means turning the ultrasonic energy on and off repeatedly in either a fixed or random pattern.  At first it seems this would would be counter-productive to the goal of maximizing the ultrasonic cleaning effect.  In fact, the blogs Ultrasonics – Ultrasonic Generators – What Is “Pulse” and Ultrasonics – Ultrasonic …

Valves – Manual Valves – Globe Valves

Today’s blog continues the discussion of valves as promised starting with manually operated valves.  There are three basic types of manual valves – the globe valve, the gate valve and the ball valve.  Of course, there are many variations of each but a look at their inner workings will reveal that they all fall into one …

Ultrasonics – Degassing Using a Pulse Degas Cycle

Using a slow rate of pulsed ultrasonics is an excellent way to speed the degassing of liquids in preparation for use in ultrasonic cleaning and rinsing applications.  The blog Ultrasonics – How to Degas Liquids explained the mechanism by which dissolved gasses are extracted from liquids by ultrasonic cavitation.  Although this degassing mechanism is very effective …

Ultrasonics – Ultrasonic Generators – What Is “Pulse”

Certain benefits can be derived in ultrasonic cleaning and processing by “pulsing” the ultrasonic generator.  In fact, different pulse rates and duty cycles produce different benefits.  This blog explores how “pulse” works and how its variants benefit ultrasonic cleaning in different ways. An earlier blog described the basic function of the ultrasonic generator. Ultrasonics – Ultrasonic Generator …
