2. The hydraulic press (a type of hydraulic machine) is a kind of special hydraulic oil used as the working medium, and the hydraulic pump is used as the dynamic force source. The hydraulic force enters the cylinder / piston through the hydraulic pipeline through the hydraulic force, and then the cylinder / There are several sets of mutually matching seals in the piston. The seals in different positions are different, but they all play the role of sealing so that the hydraulic oil cannot leak. Finally, the hydraulic oil is circulated in the oil tank through the check valve to make the cylinder / piston work circularly to complete certain mechanical actions as a kind of machinery for productivity.
3. The hydraulic internal machine is a machine that uses liquid as the working medium and is made according to the Pascal principle to transfer energy to realize various processes. The hydraulic machine is generally composed of three parts: the machine (host), the power system and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic pressar och tekniska hydrauliska pressar .
