It has simple structure and reliable operation. When it is used to implement reciprocating motion, it can omit speed-reducing device, and has no transmission gap, and its motion is stable, so that it can be extensively used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is in direct proportion to the effective area of the piston and the pressure difference between the two sides of the effective area; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder cover, a piston and a piston rod, a sealing device, a buffering device and an exhaust device. The damping device and the exhaust device are determined according to specific application occasions, and other devices are necessary. The hydraulic cylinder has various structural forms and various classification methods, wherein the hydraulic cylinder can be divided into a linear reciprocating motion type and a rotary swinging type according to the motion mode; the hydraulic pressure can be divided into a single-acting type and a double-acting type according to the action condition of the hydraulic pressure; the structure can be divided into a piston type, a plunger assembly type, a multi-stage telescopic sleeve type, a gear rack type and the like.
The plunger assembly type hydraulic cylinder is a single-action type hydraulic cylinder, can only realize the movement of one direction depending on the hydraulic pressure, the return stroke of the plunger assembly depends on other external force or the dead weight of the plunger assembly, the plunger assembly only depends on the cylinder sleeve to support and does not contact with the cylinder sleeve, so the cylinder sleeve is easy to process, therefore, the plunger assembly type hydraulic cylinder is suitable for being used as a long-stroke hydraulic cylinder, and the plunger assembly is always pressed during the work, therefore, the plunger assembly type hydraulic cylinder has enough rigidity; in the prior art, the machining process for installing the plunger assembly hole forming by the oil pipe at the bottom of the turnover oil cylinder is simple, and the machining errors are easily caused due to the fact that the effective distance of the plunger assembly is not enough.
