The cylinder is the same as the cylinder, crane
The medium of the cylinder is liquid (oil), and the medium of the cylinder is gas (nitrogen, compressed air, etc.)
2. the thrust of the cylinder is greater than that of the cylinder. Not only the high oil pressure, but also the diameter of the cylinder to avoid too big design;The 3. cylinder piston moves much faster than the cylinder piston. The gas tank shall be supplied with a large amount of rated pressure in a short time, while the high pressure oil shall be supplied by the high pressure oil pump in the course of operation, with limited flow.
The basic principle is the same, because of the different working medium, the difference is that:1. the working pressure of the cylinder is much higher than that of the cylinder. High pressure gases are much more dangerous than high pressure liquids;
