The blog Pumps – Centrifugal Pumps provided some basic information about the type of pump most commonly used in industrial cleaning equipment. Centrifugal pumps are simple, relatively inexpensive, versatile and reliable. However, as I mentioned in that blog, they do have some limitations. In order for a centrifugal pump to function, liquid to be pumped …
As I said earlier, the cleaning equipment itself is often not the source of what is perceived to be a “cleaning” problem. It is understandable, however, that blame often falls on the cleaning process as it is during the cleaning process that the problem often first manifests itself. Once a problem is detected, the solution …
When everything is going well and final inspectors are finding nothing but acceptably clean parts, cleaning can be a pretty boring part of the overall production process. As soon as a dirty part shows up, however, it seems that cleaning becomes the focus in the investigation to find out what’s gone wrong. It is automatically …
Cleanliness, as important as it is, is too often relegated to the final and “detached” stage in the process of product design. Even a very insightful design engineer seldom looks at a design from its conception with an eye to how this thing is going to be cleaned in the end. I suppose this is …
At the urging of several readers I have decided to, from time to time, present a little puzzle or “thinking exercise” here on the blog. Maybe it will help those of us who are advancing in age to stave off the effects of Alzheimer’s disease or, better yet, just offer something to think about on …
The movement of air is an important consideration in the design of most industrial cleaning systems. The immediate application that comes to mind is, of course, in drying. The movement of air is one of the major requirements for drying along with, of course, elevated temperature. In most cases, the need to move air in …
Recently, there has been a lot of attention directed at the new and expanding range of ultrasonic frequencies available in advanced design ultrasonic cleaning equipment. The result has been that there has been a de-emphasis on the “workhorse” frequencies that started it all, 25 and 40kHz. The fact is that the vast majority of industrial ultrasonic cleaning …
One thing I should have learned over the years is to not speculate on the outcome of experimentation. In the previous blog, I advanced some theories on how liquid and air exchange might be enhanced in cleaning blind holes by using a carefully directed jet of water. Then it was off the fish tank to verify …
I’ve always known that cleaning inside blind holes was a difficult task. In a previous blog, I demonstrated using video just how difficult it is to get liquids and/or air in and out of a blind hole. My plan was to approach the problem logically (largely based on intuition), and offer readers some solutions to …
We have discussed earlier the importance of drying in a cleaning process. Despite the several hardware options available, hot air dryers remain the “go to” in industrial cleaning processes today. Today’s blog will discuss the basic design concept of hot air dryers and how they function. The main components of hot air dryers are a …
