What is a Hydraulic Cylinder

Introduction to hydraulic cylinder

The hydraulic cylinder is a mechanical actuator, which is used for providing the unidirectional force by the unidirectional stroke. It is also called as the linear hydraulic motor. It is used in the several machines and in the engineering departments. Let us discuss the hydraulic cylinder.

What is a hydraulic cylinder?


Hydraulic cylinders are the mechanical machine, which gets the power by the high-pressured hydraulic fluids such as high-pressured oils. The hydraulic cylinder contains a barrel in which a piston rod is connected and it is moving in the back and forth direction. The barrel is closed at both the ends. The piston has some sliding rings and some seals. The chamber of the piston is divided in two parts. The pressure is exerted on the piston so that it can do the linear motion and then perform the useful work. The piston pushes the oil in the other chamber back to the reservoir. If we assume that the oil pressure in the piston chamber, containing the rods is approximately zero, the force FP in the cylinder times the piston area A. on the piston rod equals the pressure

i.e., F = P × A


Parts of hydraulic cylinder


There are several parts of the hydraulic cylinder. The head of the cylinder is sometimes connected to simple lock. The piston actually is short shaped cylinder metallic part that separates the barrel within. It has so many grooves, which is fit in the metal seals. The piston rod is a hard piece of chrome plated of steel which is cold-rolled. Is this topic Permanent Magnet Motor Design hard for you? Watch out for my coming posts.


Types of hydraulic cylinder


There are several types of hydraulic cylinders in the mechanical industry. The main types are tie rod fashioned cylinder and the welded body fashioned cylinder. Let us discuss them. In the tie rod fashioned hydraulic cylinder, there are high powered threaded rods made of steel, which holds the two ending caps of cylinder barrel. Small cylinders have generally four tie rods and large cylinders have 16 tie rods. In the second type of cylinder, there are no tie rods. This barrel is directly welded to the ending caps. The facade rod gland is usually threaded into or is bolted to the barrel of the cylinder, which therefore allows the piston rod assemblage and the rod seal to be detached for service.
