The hydraulic cylinder has a variety of structural forms, and its classification methods are also various: according to the movement mode, it can be divided into linear reciprocating movement and rotary swing type; according to the action of hydraulic pressure, it can be divided into single-acting and double-acting; according to the structure The form can be divided into piston type, plunger type, multi-stage telescopic sleeve type, rack and pinion type, etc.; according to the installation form can be divided into tie rods, earrings, feet, hinge shafts, etc.; according to the pressure level can be divided into 16Mpa, 25Mpa , 31.5Mpa, etc.
The hydraulic cylinder is used in the hydraulic system to drive a mechanism with a certain quality. When the hydraulic cylinder moves to the end of the stroke, it has a large kinetic energy. If the hydraulic cylinder is not decelerated, the hydraulic cylinder piston and the cylinder head will mechanically collide, resulting in impact and noise. Destructive. Hydraulic cylinder is to alleviate and prevent this kind of hazard, so it is possible to install a deceleration device in the hydraulic circuit or a buffer device in the cylinder.
