Hydraulic cylinder introduction

- Jul 26, 2018 -

A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or oscillating motion). It is simple in structure and reliable in operation. When it is used to realize the reciprocating motion, the speed reducing device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; the hydraulic cylinder is basically composed of a cylinder and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. Buffers and exhausts depend on the specific application, and other devices are essential.

The plunger hydraulic cylinder is a single-acting hydraulic cylinder. It can only move in one direction by hydraulic pressure. The plunger return depends on other external forces or the weight of the plunger. (2) The plunger is supported only by the cylinder liner. Contact with the cylinder liner, so that the cylinder sleeve is easy to process, so it is suitable for long-stroke hydraulic cylinders; (3) the plunger is always under pressure during operation, so it must have sufficient rigidity; (4) the plunger weight tends to be large, When placed horizontally, it is easy to sag due to its own weight, causing the seal and the guide to wear on one side, so it is more advantageous for vertical use.
