Where are what for are hydraulic cylinders applied?
Nowadays there are lot of machines with major task to transfer one type of energy into another. Thus, hydraulic cylinders are widely used, depending on its type and purpose, devices have different design, allowing to convert fluid energy into mechanical.
Application of hydraulic cylinders
Depending on the purpose of the machine, manufacturers of hydraulic cylinders developed several models with different operating principle. For the single acting hydraulic cylinders movement of the piston rod is being carried out by pressure of the working fluid. Piston rod returns back by the spring, gravity force of the lifted object or action of some mechanism. Such devices are used in bottle jacks. In double acting hydraulic cylinders piston rod is being returned by the fluid pressure, and they are used for manufacturing of bulldozers and lifting or lowering of the shaft.
Telescopic cylinders are widely used in the areas, where large stroke of the piston rod is required and there is no possibility to install for this purpose bigger hydraulic unit. For example, telescopic cylinders are installed at dump tracks to lift and lower body. Besides, they are used to create sliding car platform to control situations with bridges.
Thus, application of hydraulic cylinders in areas where it is required to provide a quick transfer or energy, and also change traction force and speed.
