If a filter is doing its job, its life will be limited.  Eventually it will have filtered out and collected enough particles to be severely restricted or totally block liquid flow.  When this happens, the filter or filtration media must be replaced.  A clogged filter will, at minimum, have process consequences as particle accumulations build up … Continued

The useful life of most media filters is determined by the size and quantity of particles they capture.  Each filter has only a limited number of sites to trap particles.  Once a site traps a particle, flow through that site’s passage is either reduced or stops completely.  When a sufficient number of sites are blocked, flow through … Continued

One important step on the path to solving any problem is understanding the enemy and the risk it poses.  The enemy, in this case particles, come in a wide variety of sizes and shapes.  A particle’s effect on the ultimate use of the part it contaminates may depend not only on its size, but on … Continued

Many topics can’t be covered in a single, one page blog entry.  For this reason, some of the more involved topics will be discussed in several sequential blogs with a common theme.  This is the start of one such series about filters and filtration. In parts cleaning, filtration is applied to liquids used to clean … Continued

Have a Happy and SAFE Fourth of July!

Earlier blogs have shown how difficult and deceptive it can be to relate energy consumed to work delivered.  In this blog I would like to offer an example of this difficulty as it relates directly to ultrasonic transducers and cleaning.  First of all, most (if not all) ultrasonic devices used for cleaning utilize a number … Continued

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 … Continued

“Pulse” in ultrasonic terms simply means turning the ultrasonic energy on and off repeatedly in either a fixed or random pattern.  At first it seems this would would be counter-productive to the goal of maximizing the ultrasonic cleaning effect.  In fact, the blogs Ultrasonics – Ultrasonic Generators – What Is “Pulse” and Ultrasonics – Ultrasonic … Continued

Today’s blog will let you actually hear some of the qualities of sound that are important to successful ultrasonic cleaning.  Since we humans can not actually hear ultrasound by definition, the sounds you hear will be “translated” into a sound range that we can hear.  A good starting tone is 1,000 Hz.  Sounds at 1,000 … Continued

The third of the basic types of manual valves is the “Gate” valve.  This type of valve is probably not as familiar as the others but very important in the valve family.  Although gate valves are made at least as small as 1/4″ to my knowledge, they are much more common in larger sizes.  Almost … Continued
