Lubricants and Coolants – Effectiveness vs. Cleanability
In order for a lubricant or coolant to be effective it must possess the very properties that make it difficult to remove. In industrial machining, stamping and metal forming applications, selecting lubricants and coolants wisely can greatly simplify cleaning processes … Continue reading
Metrology – Concepts in Practice
Preceding blogs on metrology have introduced some basic concepts which can serve as food for thought. Today, I would like to give you a couple of examples of the practical application of the concepts discussed so far in industrial cleaning … Continue reading
Valves – Considerations for Specifying Automated Valves
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. … Continue reading
Ultrasonics – Deburring – Fact or Fantasy?
Over the years I have had many hundred people approach me with potential applications for ultrasonic deburring. There are, in fact, many references to ultrasonic deburring in the literature going back decades in time so it’s not unlikely for the question to be … Continue reading
Valves – Pressure Reducing Valves
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 … Continue reading
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 … Continue reading
Valves – More Than Meets the Eye
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 … Continue reading
Cleaning and Rinsing – Spray Nozzles for Use in Air
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 … Continue reading
Ultrasonics – Monitoring Ultrasonic Performance
In the blog “Reader Questions – Monitoring Ultrasonic Transducers,” I suggested a couple of ways one might test individual ultrasonic transducers to assure they have not become ineffective due to de-bonding from the cleaning tank. In an extension of the spirit of that … Continue reading
Reader Questions – Monitoring Ultrasonic Transducers
Today’s blog is responding to two questions asked by readers. Both concern monitoring of ultrasonic transducer performance. Ralph Clendenin asks – “Is there a measurement of the frequency I need to be aware of during “good” operation I can check monthly … Continue reading
