Does the hydraulic cylinder change the inner ring of the cylinder?
if you do not want to buy a set of hydraulic system, and the power to the cylinder is not large, you can use compressed air to promote the hydraulic oil, hydraulic oil cylinder to drive, such as power and compressed air, but very smooth.
And the seals need to use fluorine rubber, so as not to corrode. But as to the cylinder cylinder with practice is not whimsical, there is such a usage, the pneumatic system has a natural defect, speed instability, especially in low speed, hydraulic pressure is very stable,
The cylinder can only be used under 1MPA pressure, and the use of the cylinder can only be a little bit pressure. It may not meet the strength requirements.
