| Definition and composition
Hydraulic cylinder is the hydraulic energy into mechanical energy, reciprocating motion to do (or swing movement) of the hydraulic actuators. It is simple, reliable. Use it to achieve reciprocating movement can be removed from deceleration devices, and no transmission gap, smooth motion, so in a variety of machines are widely used in hydraulic systems. Hydraulic cylinder output force and the effective area of the piston is proportional to the pressure difference on both sides; hydraulic cylinder is basically a cylinder and cylinder head, piston and piston rod, seals, cushioning device and the exhaust composition. Buffer device and the exhaust depending on the specific application of the occasion, other devices are indispensable. |
| Hydraulic cylinder type:
According to the structure used hydraulic cylinder, can be divided into four types: 1. Piston Single rod hydraulic cylinder piston rod at one end only. As shown is a single piston cylinder. Import and export of its oil port at both ends A and B can pass oil or oil return pressure to achieve two-way movement, so called double-acting cylinder. 2. Plunger (1) plunger hydraulic cylinder is a single-acting hydraulic cylinder, hydraulic pressure can only be achieved by the movement in one direction, the plunger or plunger return depends on the weight of other external forces; (2) not supporting the plunger and cylinder liner alone touch, so easy processing cylinder, so suitable for so long stroke hydraulic cylinder; (3) the total pressure plunger work, so it must have sufficient rigidity; (4) piston weight is often greater when the level is easy to place due to gravity and sag, resulting in unilateral worn seals and guide, so its use is more beneficial to the vertical. 3. Telescopic Telescopic hydraulic cylinder piston with two or more levels, telescopic hydraulic cylinder in the piston out of the order type from big to small, but empty is usually retracted the order from small to large. Telescopic cylinder can achieve a longer trip, but retracted length of the shorter, more compact structure. Such hydraulic cylinders commonly used in construction machinery and agricultural machinery. Double acting single rod hydraulic cylinder 4. Swing Swing is the output torque and the hydraulic cylinder reciprocating movement to achieve the implementation of components, also known as swing type hydraulic motor. A single leaf and double leaf forms. The stator fixed to the cylinder block, while the rotor blades and connected. Into the oil under the direction of the rotor blades will lead swinging back and forth. |
