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 …
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 …
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 is the intended goal and how it will be best be accomplished. Unfortunately, a wrong choice …
Any discussion of water quality and the purification of water will eventually gravitate to a discussion of ions. Adding ions and/or removing ions using what is called an ion exchange process is a big and essential part of most water treatment. Let’s take a few minutes to understand basically what these important things called ions are …
A previous blog Ultrasonics – Degassing – What Gas? and Why? revealed why dissolved gas is detrimental to ultrasonic performance. This blog will describe various ways in which dissolved gas can be minimized and eliminated to facilitate ultrasonic cleaning. Since the most common liquids used in ultrasonic cleaning are water and water-based solutions, the following applies …
Just about everyone is familiar with the term “hard” water but few know what it really means. In this blog I’ll try to explain what “hard” water is and why we prefer water that is “soft.” In the blog It’s Time To Talk About Water – Again, items 2 and 3 in the list of water contaminants …
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 …
It is no secret that good cleaning followed by poor rinsing can be worse than not rinsing (or cleaning) at all. A single-use rinse using a fresh water spray or a high flow rate or single use immersion rinse are often thought to provide the ultimate rinse. These options, however, are often extremely expensive because they consume …
The blog It’s Time To Talk About Water discussed the variations in water from different sources. Today’s blog is the start of a series on how to purify and prepare water for use in cleaning and rinsing applications. Water from municipal and other sources may have characteristics that are deleterious to a variety of processes. Many of …
Although the importance of “degassing” liquids prior to their use in an ultrasonic cleaning or rinsing process is pretty much common knowledge, the source of the gas and details of how to remove it are less well known. This blog is the beginning of a series which will describe in some detail where that gas comes …
