Bud,

Yes I wrote that comment, and I am sticking to it, ha, ha. Some how you have it in your brain that degree = intelligent.

A doctor in PA killed my uncle, cut the wrong leg off, staff infection set in = dead in three days. This doctor had all kinds of degrees, but could not tell left from right.

Now maybe in your small town, you simply do not see that many people with degrees walking around and you are impressed that they have them (degrees) and can tie their shoes. Here in Portland, OR the college cranks degreed kids out almost monthly like the local bakery bakes bread. If they can cross the street without being run over 10-days after graduation, we think they are smart and may have a chance. The others that do not make it across the street, well, we call them speeds bumps.

I love picking on you, it is like you came from the Ice Age, and we are trying to thaw you out without using matches.

Not really, just that trained persons have a better chance at getting it right or at least being able to understand what they are doing wrong. What they actually know becomes evident very soon to anyone they are trying to impress.
All you have to do is take a look at some post,s on this and other forums.

Normally, I would just let this topic go and not reply, but this is an important topic for people to read and understand, because you post on so many forums preaching the same subject. You imply that training and a degree will produce a very good hydraulic person.

My contention is, although training and a degree will certainly help, it also requires years in applying this knowledge before good results are seen. Most people do not want to spend the time it takes to become proficient at designing and using hydraulics, you always preach the degree thing, but seldom state that without years of application to go along with this degree, the results are less than expected.

Now, let us use your logic and apply it to you. You put on training class and write books on the subject of hydraulics. Here are my questions.

1. Do you have a degree in and or any teaching credentials to qualify you to be a training instructor or teacher?
2. Have you taken any college courses in English or any training at all that qualifies you to write books for the public on the topic of hydraulics?
3. Given that you may have the technical knowledge in hydraulics, do you have the training and or degree required to convey that knowledge in a class setting or book.
4. Do you have a degree, specifically in fluid power from any college?

I think every one would agree that being a teacher requires knowledge and training. I am not trying to degrade you in any way; however, I am applying the same standard to you, which you want to apply to Fluid Power people.

I strongly disagree with you, that a degree and a few hours of training class and you are good to go in hydraulics, as you suggest. I also strongly disagree that a degree is the only path to becoming a fluid power person.

My position has always been, that training and a degree are helpful and should be included, the actual application of hydraulic knowledge over a 5-10 year period is more critical than a degree. Moreover, a degree is not the only path to be successful in hydraulics. That said, most people will not spend the 5-10 years applying their knowledge, and will remain at the basic knowledge level until they get bored and move on to something they expect will bring them faster results.

A silly idea that people can only function in the real world if they have a degree in something, and those that do not have a degree cannot function in the real world is flat wrong.

Two things need to be done.
1. You, by your own logic need to go back to college and satisfy the items listed above; otherwise, your own logic fails you.
2. Simple door-to-door sales of fluid power parts for ten years will not make a good fluid power person (maybe a good sales person). A mix of troubleshooting, circuit design, and machine design is required, which most do not get.

Every time the subject of promoting fluid power comes up, this degree thing pops up, seldom if ever the truth is told that there is no fast track in hydraulics.

That is aout as close as we have come to being in agreement. HALELEUJIA!!!!!!

Is'nt that true of any degree in any field a person chooses to work in.

Surely you agree formal training in any field does not qualify a person as expert or even close to that title. They must work in their field for an extended period before they qualify as anywhere near expert. However, the formally trained person knows the basics and can get up to speed a lot quicker than someone off the street who may be mechanically inclined but without basic Fluid Power knowledge.

No Gary I don't but it sure would have helped in the early days. My only degree in Fluid Power and Teaching is from the College of Hard Knocks and a lot of practice. I try to not think about some of the stupid things I said and did in those first training classes but am thankful for the oppoeryunity. Now I want to pass any good from those years on.

2. Have you taken any college courses in English or any training at all that qualifies you to write books for the public on the topic of hydraulics

No again, but, I have a mentor in my home who my kids called The Hitler of Corect English since she wuld not let them, OR ME, get by with wrong English, spoken or written. I think that counts for something.

3. Given that you may have the technical knowledge in hydraulics, do you have the training and or degree required to convey that knowledge in a class setting or book.

I believe I sent you my Basic book and you sent back a dozen or so corrections out of the 275 pages. Several others have critqued the basic book and none have advised to keep it a secret. ydraulics & Pneumatics magazine is running it on their web site a chapter at a time for anyone who wants to check it out. Look on heir home page www.hydraulicspneumatics.com and go to the "ebook link." They just started a new ebook on Flud Power Circuits Expained also.

4. Do you have a degree, specifically in fluid power from any college?[/quote]

Again NO Gary, but it sure would have helped in the early days as a salesman with Miller Fluid Power. I remember spending hours on simple circuits since the College of Hard Knocks is not the best or easiest way to learn a field like Fluid Power or Electrical Engineering. Fortunately Fluid Power is a lot more forgiving than Electrical so the status quo is the way it has been handled since its inception.

Still have not convinced me that a Fluid Power degree would not be a good thing and a help for moving Fluid Power forward.

Peter wrote way back:

"So now you tell me how there can be a hydraulics degree when even if you could do the math there are no valid numbers to stick in the formulas."

With trained persons in the Fluid Power field it would seem obvious that these "valid numbers" would be forth coming.

After all you are trained and realize the need for a lot more information.

Bud, there are trained people. I have said before that major big equipment OEMS ( air craft and construciton ) have their people that analyze valves and pumps before they are used in the designs. They probably know more about the valves and pumps than the manufacturers that designed them.

I think the hydraulic manufacturers are hastening the switch from hydraulics to electrical mechanical because one can't design with hydraulic components whereas one can with electrical mechanical components.

It isn't our responsibility to do the valve and pump manufacturers' work for them by spending a lot of our time and money analyzing their hydrauluc parts.

I went to a presentation at a IFPE show where some engineer from Caterpillar talked for 30 minutes about analyzing a valve. The equations were very long and very detailed. I have never again seen so much information about a valve but this is what one must do to avoid design mistakes when designing earth moving equipment as big as a house.

Peter;

This is a wild guess to why the Fluid Power manufacturers do not give you the data you need to design your circuits accurately:

Could it be they don't have the Fluid Power expertise to know how to get that info?

Maybe their designers are only trained as Mechanical Engineers and do not know how to get the information you require???????? Could be they need some Fluid Power training in depth, Fluid Power Engineer??????

Would be interesting to hear from some of the manufacturers.

That would me the hydraulic manufacturers don't design anything. They just take previous designs and modify them. If it works and makes mony, good. If not then guess again. Design by trial and error or evolution is not very efficient.

Perhaps not but I think they can. The problem is that if we know exactly how the pumps and valves work we could objectively evaulate and compare them. Marketing wouldn't like that.

Unless they have a higher turner rate and are always hiring rookies off the street I bet engineers become expert in there valve or pumps very quickly.

yes.

Mean while I like Oddball's question. No one has tried to answer it yet.

I for one would love to Peter but they did'nt teach that in the College of Hard Knocks in any of the classes I attended.

Maybe some of the Mechanical Engineers with 2 semesters of Fluid Power classes could step up to the plate.

It looks grim.

This comment from another forum discussing Accumulators should not be true of equipment that has been around a lot of years.

"Hydraulic accumulators are very common where I work, however I'm surprised at how many new maintenance people to our facility have never seen one. When anyone asks me what "that bottle thing does""

I believe this is all too common in the world of Fluid Power equpment and application and on a lot more common equipment than Accumulators.

Maybe a couple of semesters in College or a 1 or 2 week seminar by the Flud Power manufacturers is not getting the job done????????????????

What do you expect from maintenance men that only have a high school education? They are not trained in hydraulics. The ones that have had a physics course probably went to college.

Did you notice the number of posts on plcs.net? Don't you find it distrubing that PLC programmers have more interest in accumulators than those on the hydraulic forums?

Bud, I am not near as pessimistic as you are. Look at the plcs.net forum. These guys are plc programmers but they show more interest in accumulators than those on this forum.

Maybe things are different in Arkansas, never run into any mechanics that didn't know what an accumulator was, nor about its basic function and that you damn well better valve it off before you break any lines, remove a valve, etc. I did work around an electrician, came out of the Navy nuke program that did not know what an impact wrench was-to him it was a pneumatic nut driver-once when asked to go get a come-along he thought this was a practical joke.
The electricians for the most part accept the mechanical work-goes with the territory-every once in a while we get one that wants to fix a blown hydraulic hose with a keyboard-they usually don't last long in a steel mill environment. Maytag

My point exactly Peter. I was not faulting the UNTRAINED Maintenance Person or even UNTRAINED Engineers just making a point of how a field like Fluid Power hat is so prevalentin the mechanical world is so little taughtthat Electrical Forums have better discussion by hundreds mors posters tha all the Fluid Power Forus combined. OUGHT NOT TO BE SO!!!!!!!!!!

My point exactly on why we need TRAINED FLUID POWER PERSONS like the Electrical Field.

At a local company I teach the Electrical Apprentices a 64 hout Basic Fluid Power class using the ebook that is presently on the Hydraulics & Pneumatics web site. It is sad to say that the electrical persons pick p the principles and follow the schematics much faster than mechanics since they have a background in electrical schematics. I know the symbols are different but the process is the same.

Bud, I am not near as pessimistic as you are. Look at the plcs.net forum. These guys are plc programmers but they show more interest in accumulators than those on this forum.

Take a look at the number of subscribers to each of the above forums and you don't have to wonder why the greater number of posters to the accumulator question. Albeit, you will also notice it is the same bunch that post on most of the other questions.

You still have not convinced me that there is not a need fro TRAINED FLUID POWER PERSONS. In fact it seems you may be changing your mind according to this statement. (What do you expect from maintenance men that only have a high school education? They are not trained in hydraulics. The ones that have had a physics course probably went to college.)
