What are the functions of the various components of the hydraulic cylinder

- 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 cylinder head is mounted on the upper surface of the cylinder block, and the cylinder is sealed from the upper portion to constitute a combustion chamber.

The piston is subjected to gas pressure and the piston pin drives the crankshaft to rotate through the piston pin, which is also part of the combustion chamber.

The piston rod is a connecting member that supports the work of the piston.

A seal that prevents components of gas or liquid from leaking out of the chamber.

The exhaust device is installed in the exhaust cylinder of the turbine to discharge the exhaust gas and has a function of cooling, silencing, and the like.
