Know the Pros and Cons of Hydraulic Cylinders Against to Pneumatic Cylinders

Knowing the differences between hydraulic and pneumatic cylinder systems is crucial before making a purchase or product decision since it will affect your application in a big way. Pneumatic cylinders rely on compressed air propelled by a compressor or a hand pump to provide linear motion, in contrast to hydraulic cylinder accessories that employ incompressible fluid, usually mineral oil. Both kinds of cylinders are widely used, although there are benefits and drawbacks to each.

Hydraulic Cylinder vs Pneumatic Cylinder: Pros

Hydraulic cylinders acquire one or two horsepower per pound more than pneumatic cylinders, making them the preferred choice when considering the horsepower-to-weight ratio. Hydraulic cylinders are 25 times more potent than their pneumatic counterparts of the same size when it comes to producing mechanical force.

A top-tier hydraulic pump can generate pressures of up to 4000 psi, in contrast to the 250 psi maximum output of pneumatic cylinders. Because hydraulic fluid cannot be compressed, hydraulic cylinders do not need additional fluid to maintain force and torque. Even when remote from the action, the hydraulic pump and motor may perform effectively and lose minimal power.

Hydraulic Cylinder vs Pneumatic Cylinder: Cons

Compared to their pneumatic counterparts, hydraulic cylinders are more involved and need a number of extra parts, such as motors, pumps, reservoirs, release valves, and heat exchanger and its types. A significant drawback of the cylinder is its tendency to spill liquids. Leaking hydraulic cylinders, in contrast to pneumatic ones, might contaminate other parts.

Unlike hydraulics, pneumatic actuators are usually only made for one usage unless valves and regulators are added to the cylinder. In spite of its accessibility and low cost, compressed air poses a threat to machinery when tainted with grease or oil. Pneumatic cylinders are wasteful because the compressor must run constantly regardless of cylinder motion.

Conclusion

Both hydraulic and pneumatic cylinders have their uses, and you may choose between them depending on whether you need a lightweight, compact system or one that can support a lot of weight. Now that you know when to use a hydraulic system and when to use a pneumatic system, we can enhance your systems.
