What should be considered when the hydraulic pressure is changed and the pressure is changed? Is the cost of air pressure high relative to hydraulic pressure?
Why is it necessary to change the gas? The oil leak can not be solvedThe pressure system 20MPa, ah, the aerodynamic force is not enoughLow pressure pneumatic than hydraulic cheap, but 200bar, the cost is about the samePneumatic is not recommended
This change has to be premise, there are many functions can not be replaced. Hydraulic is characterized by "incompressible" and can be "precise control."". The compressibility of the air is unstable, and the end of the movement is the full stroke of the cylinder, while the hydraulic pressure is random. This is in "accurate, safe" on the big difference, depending on your working conditions are there such requirements?
Consider 1, after the replacement function can meet the use requirements,2, after the replacement of equipment, there is still room for change.3, cost and replacement engineering difficulty4, the use and maintenance after replacement.5, environmental protection, mainly noise,
