What Is A Hydraulic Cylinder?
Hydraulic cylinders are widely used in different sectors, including construction, sanitation, and agriculture. Hydraulic systems, which are essential in power transmission, rely on these components for converting fluid energy into mechanical work. Whether it is a construction machine or a farming equipment, it is likely that hydraulic cylinders are controlling its motion. However, do you know what a hydraulic cylinder is and how it operates?
In its simplest terms, a hydraulic cylinder is a type of machine that applies fluid pressure to produce a linear force output. These cylinders are essential to machines that engage in tasks such as lifting, pushing, pulling, or pressing. Hydraulic cylinders are ideal for applications that require high force output with accuracy.
With that said, it is time to explore how hydraulic cylinders work and the different types of hydraulic cylinders in the market.
How Does A Hydraulic Cylinder Work?
Hydraulic cylinder works on the basis of Pascal’s Law which states that “Pressure exerted in a fluid is transmitted in all directions in the fluid without any change in magnitude.” In other words, hydraulic cylinders use hydraulic pressure to create mechanical movement.
Here's a step-by-step breakdown of how a typical hydraulic cylinder operates:
1. Fluid Enters the Cylinder: This starts when the fluid, most of the time oil, is fed into one end of the cylinder using a hydraulic pump.
2. Pressure Builds: When the fluid gets into the cylinder, pressure begins to increase due to the limited space. This pressure is evenly distributed over the surface area of the piston inside the cylinder.
3. Piston Moves: The force applied on the piston makes it to move in a straight line. Depending on the type of cylinder, this motion could either be an extension (pushing) or a retraction (pulling).
4. Fluid Control: Several check valves and seals help direct the hydraulic fluid in the right manner and regulate the piston’s movement.
5. Mechanical Output: This controlled movement of the piston leads to mechanical work that can lift, push, pull or press depending on the desired use.
Hydraulic cylinders are very smooth and effective in moving heavy objects with much force and accuracy. At Apex Hydraulic, our custom hydraulic cylinders are engineered with reliability and durability that would withstand many years of service even in tough environments.
Components of a Hydraulic Cylinder
Hydraulic cylinders consist of the following components which all work together to ensure the proper functioning of the cylinders. Let’s explore the primary parts:
Cylinder Barrel:
This is the barrel of the hydraulic cylinder which is used to hold the hydraulic fluid and offer the structural support necessary for the system to handle pressure.
Piston:
The piston is located within the cylinder barrel and its function is to divide the pressure zones. It is responsible for producing force.
Piston Rod:
The piston rod is connected to the piston and transfers the force that is produced inside the cylinder to the outside to perform functions like lifting or pressing.
Seals:
Seals are very important in maintaining the integrity of the hydraulic system and in avoiding fluid leakage. They are located at different locations such as the piston and the cylinder cap.
Cylinder Head and Base:
These components surround the cylinder barrel with the head, also known as the gland, at the forward end and the base at the rear end. The head usually contains a rod seal that prevents fluid loss near the piston rod
Ports:
The fluid is fed through the ports to and from the cylinder. The movement of the fluid decides if the piston should move out or move in.
Apex Hydraulic ensures that each and every component is well designed and properly put together. Focusing on sustainability and through testing, Apex’s custom hydraulic cylinders are designed to fulfill the need of the industry in terms of efficiency, durability, and reliability.
Types of Hydraulic Cylinders
Hydraulic cylinders come in a number of styles and are used for a number of purposes. Let’s take a closer look at the most common types:
Single-Acting Cylinders
Single-acting hydraulic cylinder is one of the most basic types of hydraulic cylinders. In this design, hydraulic fluid is supplied to one side of the piston and this is usually the side used to push the piston out. The backward motion is affected by an external force such as a spring or the load itself as the fluid is allowed to flow back to the reservoir. These cylinders are most commonly used in applications where the cylinder is only required to generate force in one direction, for instance in jacks or lifting mechanisms.
Double-Acting Cylinders
A double-acting cylinder has two ports: one to allow fluid to enter and extend the piston and the other to allow fluid to retract it. This design enables the cylinder to produce force in both directions, which is more convenient compared to single-acting cylinders. These types of cylinders are used in machines that require force in both directions without a break such as construction machinery and industrial automation systems. Apex Hydraulic provides a variety of double-acting cylinders perfect for applications that require control and force in both directions.
Tandem Cylinders
Tandem hydraulic cylinders involve two or more cylinders operating in a way that the force of one cylinder is multiplied by the other cylinder. All the cylinders are in series and the same fluid acts on several pistons which means higher force can be achieved with the same pressure. Tandem cylinders are perfect for use in applications that need a lot of force within a small footprint like in heavy industrial equipment.
Telescopic Cylinders
Hydraulic cylinders that have several stages (nested tubes) and are able to extend in a telescopic manner are known as telescopic hydraulic cylinders. These cylinders are able to produce longer strokes than conventional cylinders while still being small in size when recoiled. Telescopic cylinders are usually used in those cases where space is a concern but a long stroke is required, for example, in dump trucks or cranes. This makes them more flexible and wide-reaching in their operations. Apex Hydraulic offers special solutions for telescopic cylinders, providing customized products for different sectors, such as construction and sanitation.
There are several types of hydraulic cylinders and each of them is used for a particular task. The selection of the appropriate type depends on the intended use, load to be handled, and space constraints.
