Özet

Synchronization has different meanings whether used unaccompanied, and another if it is accompanied by an affix or a verb. In this context, synchronized means being the same or simultaneous with usage. The meaning of the term synchronous, which is used in the technology and computer industry, is the phase and frequency harmony between two periodically different signals. Therefore, synchronization is often used to describe the pairing status between technological devices. Today, there are automatic controlled systems as well as manual-operation controlled hydraulic systems used in the control of slow and structural movements. The system allows pressures and movements to be controlled simultaneously according to the values measured by the position sensors. Typically operating simultaneously with a maximum collection of units working together in a cycle suited to operational needs, the system also compensates for flow variations and/or pressure using position measurements, generating real-time information, authorizing predefined movements to be completed.

In order to increase the efficiency in hydraulic systems, synchronized circuits are used without any problems. A number of hydraulically actuated systems with multiple cylinders require the cylinder strokes to be synchronized in order to function properly and move together. The purpose of the methods used in the synchronization of the cylinders is to ensure that the cylinders and the elements operate in a stroke with the same time and velocity when all the loads, pipe diameters, lengths and frictions are equal. The accuracy of these methods depends on the power of the equipment and the location of the load. Mechanical methods are often used to properly synchronize the air cylinders. The most common mechanisms in external mechanical equipment by which the cylinders are synchronized are racks and pinions, crankshafts, cables and pulleys, and chains and gears. In the mechanical synchronization method, it is ensured that the cylinders operate in any place at the specified stroke, without leaving the working phase. The most accurate, but an expensive method of synchronizing hydraulic cylinders is using servo valves. In synchronization, servovalves control each cylinder independently with electronic position feedback and compare the position of each actuator with the others.
