YOUR GUIDE TO HYDRAULIC CYLINDERS

HOW DOES A HYDRAULIC CYLINDER WORK?

Hydraulic Cylinders work on a very simple principle. The cylinder barrel contains oil or some type of fluid. The barrel has a piston mounted inside and can be made to move in a linear route. The piston then extends/retracts when force is exerted on the fluid.

These units have been designed to take into account the specific applications that they have to support, with hydraulic force calculated by multiplying the area of the piston and the pressure inside the barrel.

Hydraulic Cylinders form the motor part of a system, while the hydraulic pump functions as its generator. The pistons work by pushing the oil from the reservoirs into the various compartments. If the oil pressure inside the piston rod compartment is zero, the force on the piston rod is calculated by multiplying the pressure in the piston rod areas and the pressure of the cylinder. In this case, if oil is pumped into the side-chamber of the piston rod, the piston shifts downwards and the oil, from the piston, returns to the reservoir without pressure.

BENEFITS OF HYDRAULIC CYLINDERS

• Hydraulic cylinders are particularly noted for their ability to exert tremendous force, which is mainly calculated in terms of lbs per square inch, on an object or inside mechanical equipment. This technology allows machines to undertake mammoth tasks with ease.
• They can provide enormous power to machines even if they are located far away from the power source.
• The cylinders have efficient power-to-size and power-to-weight ratios.
• They come equipped with hydraulic speed control and automatic overload protection.
• Noted for their dimensional accuracy.
• Can provide constant torque despite changes in speed.
• Require lesser moving parts for their operations, and hence, they are easy to maintain compared to electrical and mechanical systems.

TAKE PRECAUTION

However, the use of Hydraulic Systems calls for special precautions. Hydraulic lines may rupture, leading to severe risk of injury. Leakage may result and hydraulic fluids may catch fire and the risk is especially high for installations located in hotter regions. Therefore, you should make sure that you study every application, in detail, before you select a hydraulic system to support it.
