Hydraulic cylinder is a machine that can transform the hydraulic energy into linear motion mechanical work.
According to the version of hydraulic cylinder, the assortments of hydraulic cylinder can be divided into four types:
- Piston type: single piston rod hydraulic cylinder only has a piston rod in one end. Both ends of oil ports A and B can not only come in but also come out pressure oil or return oil in order to effect bidirectional movements. It is also called double acting cylinder.
- Plunger type:
(1). The plunger type of hydraulic cylinder is a single function type hydraulic cylinder. The direction of movement is depending on hydraulic pressure, and the return of plunger piston must rely on external forces or piston’s dead-weight;
(2).The cylinder sleeve support but not get in touch with plunger piston, so process this cylinder sleeve is very easy, and will be suitable for making long trip hydraulic cylinder;
(3).The plunger type of hydraulic cylinder should be strong enough to endure pressure;
(4).the weight of plunger piston is always heavy, it will droop due to self-weight when you level placed, lead to sealing elements and guild sleeve uneven wear, so it is good for us to vertical placement.
3. Telescopic type: the telescopic type of hydraulic cylinder has two or multilevel pistons, because the telescoping cylinder can achieve long trip, and he return trip is shorter, the structures are compact. So this kind of hydraulic cylinder is often used in engineering machinery and agricultural machinery.
4. Swing type: swing type of hydraulic cylinder is a machine that can output torque and realize shuttling; it is also called oscillatory motor. The stator block is fixed in cylinder body, and the blade connects with rotor. According to the direction of oil-taking, blade will bring the rotor swing repeatedly.
