Structure and Working Principle of Hydraulic Cylinders

A hydraulic cylinder consists of a piston and a cylinder that moves due to the pressure of hydraulic fluid. Within the equipment, the pump generates a pressure differential that creates the fluid pressure.

It is important that the hydraulic system is closed, so the fluid never exits but remains in circulation. When the pump pushes fluid into the cylinder, the pressure causes the piston to perform linear motion, carrying out mechanical work.

Types of Hydraulic Cylinders

One of the most common cylinder types is the telescopic cylinder, widely used in mobile hydraulics, such as in trucks, trailers, and lifting equipment. The telescopic structure consists of multiple, retractable sections, allowing it to extend further and retract compactly.

Our MPH webshop offers a range of telescopic dump cylinders to choose from.

The double-acting or actuator cylinder allows the piston to move in both directions under hydraulic pressure. This type consists of two separate chambers located on opposite sides of the piston. Hydraulic fluid pressure can be applied to both chambers, enabling the piston to move forward and backward.

The rotary cylinder performs a rotating motion instead of a linear one. Its application is quite specific, for example, in rotating tables.

Hydraulic pumps, responsible for generating the system’s operating pressure, are essential for the efficient operation of the entire system. Parker piston hydraulic pumps provide reliability, long service life, and stable performance in every case.

Key Characteristics of Hydraulic Cylinder Operation

The widespread use of MEILLER hydraulic cylinders is no coincidence, as they possess many features that justify their popularity.

Even in a compact size, they can exert significant force, which is a vital factor in various applications.

In addition to high performance, precise and easily controllable work is also possible. This makes them an ideal solution for tasks that require delicate and precise operations.

Their advantageous properties include durability and long service life, allowing for sustained performance even under harsh conditions and intensive use.

Regular maintenance is recommended to preserve optimal condition, ensuring efficient operation. Pay attention to the manufacturer’s warranty conditions, as some warranties require proof of maintenance work.

The versatility of hydraulic cylinders allows them to be used in numerous industries, such as construction, agriculture, automotive, and even aerospace.
