It is not an uncommon practice to use flow restricting valves in an effort to reduce and/or control pressure in even the most sophisticated industrial cleaning machines. In the blog “Reducing Flow vs. Reducing Pressure – Which is it?” the risks of using flow restricting valves to control pressure were discussed in some detail. Reliable pressure control …
Today’s blog will let you actually hear some of the qualities of sound that are important to successful ultrasonic cleaning. Since we humans can not actually hear ultrasound by definition, the sounds you hear will be “translated” into a sound range that we can hear. A good starting tone is 1,000 Hz. Sounds at 1,000 …
The third of the basic types of manual valves is the “Gate” valve. This type of valve is probably not as familiar as the others but very important in the valve family. Although gate valves are made at least as small as 1/4″ to my knowledge, they are much more common in larger sizes. Almost …
The ball valve is the most common example of a whole family of valves that include rotary valves, piston valves and other valves that use selective positioning of an inner core with one or more through-holes or cavities to direct flow from one or more inlet ports to one or more outlet ports. I realize that the …
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 …
Valves that control the flow of a liquid or gas are an obviously important part of any cleaning system. What isn’t so obvious is the sheer number of valves that are involved and that the selection of the correct valve for a particular purpose is a little more complex than one would think. In simple terms, a …
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 …
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 …
A rose is a rose is a rose. But pumps, now that’s a different thing. Pumps, even though they may look physically the same, can vary significantly in their ability to pump liquids under various conditions. In order to know how a pump will perform in a particular application, one must rely on something called …
Previous blogs have suggested the use of liquid sprays in air as either a primary mechanism or as an enhancement to both cleaning and rinsing operations. Today’s blog will discuss, briefly, what is important in choosing a spray nozzle or nozzles for a particular application. In order for spray to be effective, of course, the …
