Hydraulic Cylinder Parts

Hydraulic cylinders are extensively used in automotive machines. This article describes the various parts of these devices, which help in their normal functioning.
In today's world, we see hydraulic systems being used everywhere. All the big machines that you see on your daily drive function on the basis of hydraulics (study of the mechanics of fluids). This branch has helped to reduce the workload of other machines. Heavy duty tasks, such as lifting cranes, digging, or crushing huge boulders have now easy because of the principle of hydraulics. A hydraulic cylinder or motor is one of the various mechanical devices used in engineering vehicles. These machines make use of the pressurized hydraulic fluid in order to produce a linear force.

Hydraulic Cylinder Components
  • Cylinder Barrel:With the help of this part, the piston makes back and forth moments. The barrel is a unlined thick walled pipe, which is perfected internally, and is situated inside the cylinder.
  • Cylinder Head:It is connected to the barrel with a lock or screw.
  • Cylinder Bottom:The barrel and bottom portion are welded together in most hydraulic cylinders. In most cases, this damages the inside of the barrel if done in an improper manner. However, many upcoming new designs have a screwed connection from the cylinder end cap to the barrel so that rebuilding this device is possible.
  • Piston:It is defined as a short cylinder shaped metal component, which is used to separate both sides of the barrel. This component is usually forged with grooves or metal seals, which prevent the hydraulic oil to pass through it to the chamber on the opposite side. Seals are of different designs, and are made to suit the temperature and pressure requirements of the cylinder.
  • Piston Rod:It is chrome plated piece of cold steel, which is attached to the piston. This part rod joins the hydraulic actuator to the machine component that helps the cylinder to accomplish a given task. A machine thread or a mounting attachment can be used for this connection.
  • Rod Gland:To make sure that the pressurized oil doesn't leak, the cylinder head is fitted with seals known as rod gland. It also has another seal called rod viper that works as a block to stop contaminants from entering in the cylinder.
The above-described components of this system ensures proper functioning of the automotive machine.
