Hydraulic cylinders work on the principle of converting hydrostatic energy into mechanical energy. They are motors or actuators which are capable of producing work. Hydraulic cylinders are different from hydraulic motors and carry out a linear or translator movement instead of a rotator one. The force produced by a hydraulic cylinder F in Newton is related directly to the maximum operating pressure P in bar and the effective area of the piston A in square centimetres as F = P X A. A hydraulic cylinder converts energy stored in hydraulic fluid in to a force which is used to move the cylinder in a linear direction.
There are two kinds of hydraulic cylinders according to function:
- Single Acting Hydraulic Cylinder
- Double Acting Hydraulic Cylinder
According to specifications there are four kinds of hydraulic cylinders:
- Plunger Hydraulic Cylinder
- Telescoping Hydraulic Cylinder
- Cable Hydraulic Cylinder
- Diaphragm Hydraulic Cylinder
Hydraulic cylinders are useful in mobile applications such as excavators, loaders, dump tracks, graders, back hoes and dozers and others. The cylinders can push, pull and lift loads of any type with the mobile machinery industry relying exclusively on these kind hydraulic cylinders for linear motion. Hydraulic cylinders are also used many a times in industrial machinery industry. Power density of the hydraulic cylinder is totally unmatched which makes it great for presses, compactors, forging presses, injection moulding and others. Even for advanced applications like flight simulators or fatigue testing, hydraulic cylinders can be used in any linear motion application. Due to their various applications in the industrial sector hydraulic cylinders are essential and many industrial processes might not work without them. The need for hydraulic cylinders is ever growing and will continue to increase in the future also. For more information on hydraulic cylinder repair visit company JAM Hydraulics Pty Ltd.
