The working principle of hydraulic cylinder mainly has five components. Let's start with its basic 5 components: 1 - cylinder barrel and cylinder head, 2 - piston and piston rod, 3 - sealing device, 4 - buffer device, 5 - exhaust device.

The working principle of each cylinder is almost similar, take a manual jack, the jack is actually a simple cylinder. Through the manual booster straw (hydraulic hand pump) to make the hydraulic oil through a check valve into the cylinder, at this time into the cylinder of the hydraulic oil because of the single valve can no longer fall back, force the cylinder rod up, and then do work to continue to make the hydraulic oil continue to enter the hydraulic cylinder, so that it continues to rise, to lower when the hydraulic valve is opened, so that the hydraulic oil back to the tank, this is a simple working principle, others are improved on this basis, the principle of the cylinder and the cylinder is basically the same.
