The hydraulic cylinder can be divided into piston cylinder, plunger cylinder and swing cylinder from the structure. The working principle of the hydraulic cylinder is: When it comes to its working principle, it must first talk about its most basic five components, 1- cylinder cylinder and cylinder head 2-piston and piston rod 3- sealing device 4- cushion device 5- exhaust The work of each cylinder of the device is almost the same. Take a manual jack for the job. The jack is actually the simplest cylinder. The hydraulic oil passes through the manually pressurized stalk (hydraulic manual pump). A single valve enters the cylinder, and the hydraulic oil entering the cylinder cannot be reversed because of the single valve, forcing the cylinder rod upward, and then continuing to make the hydraulic oil continuously enter the cylinder, so that it continuously rises, Open the hydraulic valve and return the hydraulic fluid to the tank. This is the easiest job. Everything else is improved on this basis.
