I am not talking about turning the motor on and off. I am talking about the action of loading & unloading itself (switching of the unload valve at the suction) and whether the frequency of that can contribute to issues like oil carry-over, etc. Gut says yes because I've seen cases where it...
The original question only came up because the field vendor didn’t understand the difference between adjusting influent hardness vs adjusting salt dosage
There’s two different systems. In one we are recalculating the time between regeneration by changing the influent hardness set point. That’s what I was asking about.
In our main system we are changing the actual salt dosage.
My site uses regulated compressed air to unload our rail cars to pump maybe around 200 gallons a minute (30 acfm at 40 psig) to storage. During the end of unloads vortex formation allows air to go directly through without the typical downstream pressure of the fluid being unloaded such that the...
@bimr That still doesn't explain what the salt dosage is. Does it affect the brine draw, etc.?
I don't want to change salt dosage. I want the actual influent hardness (20 ppm) to be accurately reflected in the "gallons treated" capacity that determines when the system is regenerated. The...
So the resin bed is spent the same regardless of the influent concentration?
I'll just work through it with the corporate SME engineer... Your answer is very confusing. It also didn't resolve what the salt dosage actually corresponds to. Is it just used for the calculation for the capacity...
We have a series of smaller softener units that take pre-softened water as an inlet and soften it additionally to make it "super soft". Essentially our bulk softener softens to a maximum of 5 ppm leakage and then these additional polishers are there in case the main softeners failed and went...
1.5 minutes of max flow. I don’t think they’re inadequately sized but since the pressure isn’t reduced from compressor pressure we’re very susceptible to high use periods.
Have two 100 HP rotary screw air compressors that modulate via loading/unloading. Last compressor analysis indicated very frequent load/unload cycles (maybe once a minute per compressor). This is because we don’t regulate pressure after the compressors and various processes use a lot of it...
Studies performed on a quenching unit we have indicate fluoride/chloride levels are significant factors in degrading the mortar and brick. Are there any cost-effective industrial methods for fluoride/chloride removal from a stream containing 4 ppm fluorides and other typical fluids found in...
I'm re-doing a small natural gas pipeline and wanted to use a typical two-part epoxy for the piping with a corrosion wax tape applied over fittings, welds, valves, and support sections to further reduce the potential of corrosion to those parts. Is this a typical use case for corrosion wax tape...
There are several mag drive pump manufacturers our company uses across several sites (Iwaki, Innomag, Ansimag, Finish Thompson)...
Do all these manufacturers provide some sort of niche or are they all just built to the same ASME or ISO standard? What are the primary differences between these...
Why are some spray nozzles designed with the external nose geometry flat vs. chamfered? My assumption was that turbulent eddies that might generate at the leading edge would be less turbulent with a chamfered edge. The application here is vertical hot gas being cooled by spray water coming...
Most manufacturers recommend against group trapping due to backpressuring of the separate legs and potential flooding / hammer.
Are there cases where group trapping is either possible or preferred? We have a trace system where there are a large amount of vertical nozzles requiring heat trace...
My apologies I thought you were talking about Ultramet. Could we potentially laser clad ultimet to the C276 to avoid a potential catastrophic failure if there were some unforeseen mechanism? Here's another picture of the pretty scaling on the nozzle for your troubles - keep in mind this was...
