Can the cylinder be transformed into a hydraulic cylinder?

Replace hydraulic cylinder with air cylinder, because air cylinder and hydraulic cylinder are suitable for different systems, and the sealing form and structure are also different. That is to say, the oil resistance of cylinder seals may not be as good as that of hydraulic cylinders. The key is to see what kind of system you use and how stressful it is. Generally, the hydraulic system has high pressure and low air pressure. When the cylinder is used as a hydraulic cylinder, it may be unbearable and there may be safety problems such as the possibility of cylinder explosion. The common pressure of general hydraulic pressure ranges from several megapascals to dozens of megapascals, and the air pressure is mostly below one megapascal, so it needs to be clear and used with caution.
