Hydraulics and Pneumatics 47,148 Items
Description: All types of machines need some power that allows them to do specific tasks. The two most efficient types of power for machines are the pneumatics and hydraulics. They can be designed to rotate, turn, push, lower, list, and move machines carrying huge loads. Hydraulics operates using the principle of fluid pressure that forces a mechanical action. Hydraulic circuits comprise a pump that helps to compress fluids, conduits that carry fluids to the targeted section of a machine, and a piston that generates the expected effect. The main benefits of hydraulics include: 1. The liquid used on the system does not absorb energy. 2. They are able to move very heavy loads and provide higher forces because of incompressibility of liquid. 3. They are highly responsive when compared to pneumatics. 4. Hydraulics can perform many tasks at any one time. For example, they can cool, transmit power, and lubricate. Pneumatics are in many ways similar to hydraulics but instead of fluid, they use gas. This means that air is pushed by a compressor and forced through pipes to specific tools. Pneumatics are mainly used for hand tools that perform repetitive motions. One example is the jackhammer. The main advantages of using pneumatics include: 1. They are simple in design and application. The machines using pneumatics use standard cylinders and run via simple on-off controls. 2. Pneumatic systems are safer compared to hydraulics. Unlike the hydraulics that can result to fire accidents from compacted oil, pneumatics are safer because they only compress air. 3. Pneumatic systems are highly reliable because of their long operating lifespan. They also require little maintenance because the devices are not subject to shock damage.
