Classification Of Hydraulic Cylinders

- Dec 26, 2017 -

The hydraulic cylinder's structure form is various, its classification method also has many kinds: according to the Movement method may divide into the linear reciprocating movement type and the swing type; According to the liquid pressure action can be divided into single action, double action, according to the structure can be divided into piston-type, plunger type, multistage telescopic sleeve type, gear rack type, etc. according to the installation form can be divided into levers, Earrings, bottom foot, hinge shaft, etc. according to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

Piston type

The single piston cylinder has a piston rod at one end. As shown in the figure is a single piston hydraulic cylinder. Both ends of the import and export of oil ports A and B can be through the pressure oil or oil back to achieve two-way movement, it is called double acting cylinder.

The piston can only move in one direction, and its opposite movement needs to be done by external force. But its stroke is generally larger than the piston type hydraulic cylinder.
