How do you run two hydraulic cylinders together?

One common method to run two hydraulic cylinders together is by using a parallel circuit configuration. In this setup, both cylinders are connected to a common hydraulic power source, such as a pump or an accumulator. The parallel circuit allows for simultaneous operation of both cylinders, which can be beneficial in various applications where coordinated movement or increased force is required.

The parallel circuit configuration involves connecting the rod end of one cylinder to the rod end of the other cylinder, while the cap end of both cylinders is connected to the hydraulic power source. This arrangement ensures that the same pressure is applied to both cylinders, resulting in synchronized movement.

The concept behind this configuration lies in Pascal's law, which states that the pressure exerted on a fluid in a closed system is transmitted equally in all directions. By connecting both cylinders to the same hydraulic power source, the pressure is distributed equally to each cylinder. As a result, both cylinders extend and retract at the same rate, allowing for smooth and coordinated movement.

The use of a parallel circuit configuration offers several advantages. Firstly, it allows for the doubling of force capacity. By running two cylinders together, the combined force output is effectively doubled. This can be particularly advantageous in applications that require heavy lifting or pushing.

Additionally, running two cylinders together provides increased stability and balance. As the force exerted by one cylinder is countered by the force exerted by the other, the load remains evenly distributed. This helps prevent any uneven stress or strain on the hydraulic system, ensuring its longevity and optimal performance.

Furthermore, the parallel circuit configuration enhances overall operational efficiency. By enabling simultaneous operation of both cylinders, the parallel circuit reduces the time required to complete a task. This can be especially valuable in time-sensitive applications or those that involve repetitive tasks.

In conclusion, running two hydraulic cylinders together is achieved through a parallel circuit configuration. By connecting both cylinders to a common hydraulic power source, they operate in synchrony, thanks to Pascal's law. This setup offers increased force capacity, stability, and operational efficiency, making it a practical choice in various hydraulic systems. Whether in industrial equipment, construction machinery, or automotive systems, the ability to run two hydraulic cylinders together is a valuable solution for many applications.
