I highly appreciate your comment, it shows that even if I am not as you assume "a technical man" you are totally uneducated in hydraulics.
I would suggest before you make such comments to take a book about industrial hydraulics and read it a bit. May be you will understand it and then you will change your mind may be you will not understand since it could be too complex for you and then you will stay with your opinion.
Any way when you make such comments with the intention to insult it would be better -for you- to take the responsibility giving also the reasons for the comment and register not staying as a guest only.
Since it is the end of the year I forgive you for your rude attitude and wish a VERY good year 2009 with the hope that you will become a better "technical man" in hydraulics after you will learn what this stuff is! Happy New Year
I wrote this comment already but I do not know why it did not appear. So that I repeat it even with not same words.
I can understand that some body not having any knowledge about hydraulics asks even questions which cannot be answered on a forum as CR4 but I consider as dangerous that some body takes the responsibility to give an "expert" answer not knowing about what he speaks.
If an answer is given the person who did it takes a responsibility toward the receiver of the answer, if he does not know enough about the subject it is better to stay put in his corner and learn if other more responsible persons give an answer or if he wants to manifest his presence it is the least he can do to write as introduction : " It is not my field but I try to give you an answer with a qualitative and limited validity....".
If we expect respect from the persons asking question they also deserve respect concerning the quality of our answers.
Critisizm of any kind will deter people from ansering any question. So please do not critisize. Yes forging presses are made of heavy tonnages and the hydraulic circuitary depends on the cycle of operation.
I am very sorry but I cannot accept stupid answers, it is better to have few good answers than more unprofessional which could harm the person who asked the question.
We are not at a brainstorming session where criticism is not recommended but we have to give a PROFESSIONAL answer to a question it a proof of the respect we have for the one who put the question.
If people who claim to be professionals do not accept criticism this means they are NOT professionals. The true engineer is not afraid of critics, if he is convinced that the critical comment is correct he will accept it if he does not he is not a professional.
Of course he will try to defend his ideas but he will also learn from critics since we are not perfect and need to learn every day more.
Where would be the world without critical opinions? May be still in the stone age.
