What is the difference between a pneumatic support rod and a hydraulic support rod
Author:
1. Their media are different, one is compressed air and one is hydraulic oil. 2. Their bearing capacity is different, because the pneumatic pressure is generally below 1MPa, and the hydraulic pressure is generally below 30MPa (domestic). Above this value, the requirements for components and pumps under ultra-high pressure are too high. Because the pressure (which we commonly refer to as the pressure, which refers to the number of MPa and kilograms) is high, the driving force is also high. 3. Hydraulic oil is recycled and pneumatically used up gas is no longer recycled. 4. Pneumatic components are more beautiful than hydraulic components. 5. In factories, centralized air supply is generally used for pneumatic operation, and hydraulic pressure is typically one machine per hydraulic station. 6. Hydraulic control has higher operating accuracy than pneumatic control (due to high compressibility of gas)
