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 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 …
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 …
Almost every cleaning system incorporates at least one pump. Understanding how that pump works and how to treat it with the gentle, loving care it deserves is critical to the successful operation and maintenance of a cleaning system. Pumps are, in general, devices which impart added pressure to a flow of liquid. Although there are a number of different …
I thought that title might get your attention! Actually, this blog is about “stuff” including, literally, “rocks” that can be found in many water supplies both municipal and otherwise. It is important to differentiate between things that are dissolved in water that leave “rocks” behind when the water evaporates and things that are in the …
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 blog, quality control measures for ultrasonic cleaning performance, I decided to check out a paper I …
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 that would show reduction in cleaning due to change in frequency?” Stephen Sharkey asks – …
The preceding blog addressed the most common service issue with ultrasonic equipment, the ultrasonic generators, along with Preventive Maintanance measures that can help minimize generator failure events. Today’s blog will cover additional Preventive Maintenance measures which apply not only to ultrasonic cleaning equipment but to the broader range of cleaning equipment of all types as …
Reader’s Questions The blog welcomes reader’s questions and comments related to cleaning. Just forward questions or comments to jfuchs@ctgclean.com. Provided I know the answer to your question, I will either answer it by email or, if the question is of general interest, I will answer it in the blog. If I don’t know the …
