The simplest approach is to design a flow-divider circuit that will maintain the same cylinder velocity by maintaining the same flow rate to the cylinders. The performance of the synchronization is dependent upon the performance of flow-divider as well as the compressibility of the working

    One advantage of mechanical synchronization is that the cylinders can operate anyplace in the stroke without getting out of phase. The accuracy of mechanical synchronization is about ±0.005 to 0.010 in. -- depending on load variation and strength of the mechanism used. The most accurate way to synchronize hydraulic cylinders is with servovalves.How to Synchronize Hydraulic Cylinders,2016-2-17 · The problem of synchronizing hydraulic actuators arises in many applications, where the synchronous operation of multiple actuators under load has important performance implications.

    Synchronizing cylinder Double-acting cylinder with two piston rods. The velocity is the same in both directions if both piston rods are the same thickness and the same flow rate acts on both piston areas.Synchronizing circuits Hydraulics & Pneumatics,2021-2-15 · One of the considerations in synchronizing cylinders is leakage replacement. Under normal pressure, leakage can be practically zero over one stroke. Accumulated error is the main concern. A replenishing circuit, which replaces leakage after each cylinder stroke, eliminates this trend.
