Working principle of hydraulic lifting platform and hydraulic cylinder

It has the most basic 5 parts: 1- cylinder and cylinder head 2- piston and piston rod 3- sealing device 4- buffer device 5- exhaust device


The work of each cylinder is almost the same, let me take a manual jack for example, the jack is actually the simplest oil cylinder. Through the manual supercharging stem (hydraulic manual pump) to make the hydraulic oil through a single valve into the cylinder, then the hydraulic oil into the cylinder because of the single valve can not go back to force the cylinder rod up, and then continue to make the hydraulic oil continue to enter the cylinder.
