How Many Types of Hydraulic Cylinders Are There?

There are a variety of hydraulic cylinders in India types and designs to consider for your application. Each has its own set of benefits and is best suited to specific types of applications. We'll take a quick look at the different sorts of hydraulic cylinders in this article.

Single acting and double acting cylinders are the most common types of hydraulic cylinders, Telescopic or tandem cylinders may be required in some applications.

1) Cylinders with a single action

The piston force of a single acting hydraulic cylinder is applied in a single direction. As the cylinder contracts at the head end, the working stroke is pushed outward, hence the alternate name of 'push cylinder.' Because the force only flows in one direction, the return stroke is reliant on either an internal spring mechanism or an external motor.

2. Cylinder with two acting pistons

Hydraulic cylinders with two working pistons can exert force in two directions. The piston cylinder is split into two pressurized chambers, allowing the rod to perform both outward and return strokes independently. A unique sort of hydraulic fluid transfers mechanical energy to the piston surface.

Double-acting cylinders come in a variety of shapes and sizes:

a) A traditional double acting cylinder has a single piston shaft and only applies force in one direction. They are employed in applications that open and close doors, raise arms, and so on.

Non-differential cylinders, also known as Double Rod cylinders, have two rods, one on each side of the piston surface. One rod's outward stroke is equal to its opposite number's return stroke. The hydraulic cylinder can oscillate back and forth by alternating the pressure in the two piston chambers.

c) In contrast to unbalanced hydraulic cylinders, which have chambers of differing sizes/pressure potential, balanced hydraulic cylinders contain two equal compression chambers that exert the same force in both directions.

d) Cushioned hydraulic cylinders have a limiting device at the piston head to reduce excessive load at the outward stroke's conclusion. Manufacturing double acting hydraulic cylinders by Hydraulic Cylinders Manufacturer is straightforward and inexpensive, and they are exceedingly versatile. They're commonly found in construction equipment, manufacturing machinery, and automobiles.

3) Hydraulic Cylinders in Pairs

Tandem hydraulic cylinders consist of two distinct cylinder barrels joined by a single rod that connects each barrel's piston head. The rod enters the base end of the associated cylinder and pushes the piston surface when the first cylinder is pressurized, magnifying and transmitting the force. The force available from small cylinders can be amplified by using tandem cylinders. It also saves energy within a system because only the first cylinder requires outward pushing force. The return stroke is made feasible by pressurizing the piston end chamber of the outermost attached cylinder, as is the case with most tandem cylinders. Three or more cylinders can sometimes be connected in parallel stages.

4) Actuating Hydraulic Cylinders (Telescopic/Multistage/Ram Type)

Telescopic cylinders are made up of a series of smaller cylinders that are nested together. It's not uncommon for there to be up to six stages. In a similar way to a tandem cylinder, the cylinder barrel works as the piston rod, sending force to the next cylinder. Long-reach equipment, such as crane lifts and digger arms, frequently use telescopic cylinders. The return stroke of most telescopic hydraulic cylinders is controlled by a spring mechanism.
