Working Principle of Hydraulic Cylinder

Hydraulic cylinder is a device that converts hydraulic energy into mechanical energy. It usually consists of piston, cylinder, piston rod, end cap, etc. According to the structure and working principle, it can be divided into piston hydraulic cylinder, telescopic hydraulic cylinder, swing hydraulic cylinder and other types.

Piston hydraulic cylinder: there is only a piston rod, two inlet and outlet ports, you can pass the pressure oil or return oil, to achieve two-way movement, so it is known as double-action cylinder.

Telescopic hydraulic cylinder: with two or more stages of the piston, the piston extends the order from large to small, while the no-load retracted order is generally from small to large. Telescopic cylinders can achieve a longer stroke, while the retraction length is shorter, more compact structure.

Oscillating Hydraulic Cylinder: An actuator that outputs torque and realizes reciprocating motion, also known as an oscillating hydraulic motor. There are single blade and double blade two forms. The stator block is fixed on the cylinder block, while the blades and rotor are connected together. According to the direction of oil feed, the blade will drive the rotor for reciprocating swing.
