Inadequate or improper agitation of parts in a cleaning tank is a common problem in industrial cleaning. Agitation, if properly applied, can be a very powerful aid to cleaning. The result of improperly applied agitation, however, can range from disappointing to disaster. The basic reason to agitate a part in a cleaning tank is to provide or …
The specification of automated valves requires certain considerations that are not of concern with typical manually operated valves. The blog Valves – Automated Valves – What’s Different? provided a glimpse of automated valves with a very simple (but typical) example. There are, of course, innumerable variations used in the design of automated valves so the …
Today’s highly automated industrial cleaning equipment relies heavily on valves remotely actuated either by an operator or by an automated control system. Although performing basically the same function as manually operated valves, automated valves operated by electricity, air, hydraulics or other means are considerably different than manual valves not only in their construction but their mode …
I’ve been “playing” with ultrasonics for over two-thirds of my life now and am absolutely convinced that there is still more to know about the technology than anyone knows. The “fish tank” in the lab continues to reveal more questions than answers when it comes to this complex technology. The Ultrasonic Fish Tank in the Lab Still, …
This blog wasn’t meant to be a April Fool’s day piece but the more I look at it, it might suffice. Sorry it’s a couple of weeks late! For most engineers, words are usually a more or less “get-R-done” proposition. As an engineer, then, I may be a bit weird in that I really pride myself …
The word “passivation” is one that is thrown around quite a bit in the metal finishing and cleaning world and seems to have a world of different meanings to different people. Although the word passivation is normally associated with stainless steel, there are several other metals that can be “passivated” in one way or another. …
Over the years I have had many hundred people approach me with potential applications for ultrasonic deburring. There are many references to ultrasonic deburring in the literature going back decades in time so it’s not unlikely for the question to be asked. In fact, ultrasonic deburring may have limited application but requires certain very special circumstances in order …
Well, sometimes stuff happens! As I was checking the blog today I discovered that the wrong sound clip somehow wormed its way into yesterday’s blog Sounds of Silence – Pulse Period and Duration I have made the appropriate correction and now the sound clips in the published blog are actually the ones that they should …
Today we are, again, going to bring ultrasonic sounds into the realm of human audibility by lowering the frequency to ones that most people with normal hearing can hear. Several preceding blogs have discussed the effects of varying the pulse width and pulse period of an ultrasonic generator in an ultrasonic cleaning system. If you’ve …
Pressure regulating valves were discussed in the preceding blog Valves – Pressure Reducing Valves. Pressure reducing valves, although commonly used where pressure is an issue, are not always the best alternative. The pressure reducing valve has a close cousin called a “Back Pressure Regulating Valve” which monitors and controls pressure in a similar but different …
