Pneumatics and hydraulics are two types of technologies used in industry to facilitate high-pressure fluid transfer. Typically, pneumatics refers to compressed air while hydraulics refers to liquid-filled systems. Both are integral components of a comprehensive industrial application and offer a variety of advantages. This article provides an overview of 81513600 application fields and their working principles.

Pneumatics

Pneumatics is a technology involving the use of compressed air to power various pieces of equipment. It is suitable for medium-pressure applications where the application requires air pressure in the range of 7 to 10 bar. Some of the common applications include control and actuation of valves, animation, medical assistance, and robotics.

At the heart of a pneumatics system is an air compressor, which is responsible for pumping air through the system. Depending on the application, the compressor may be supplemented with additional components, such as pressure boosters, filters, dryers, and silencers. The air is then routed through a series of pipes, tubes, and fittings to the point of use, which may include an actuator, a nozzle, or a cylinder.

Once the compressed air reaches the component, it is used to power a variety of functions. The most common is powering an actuator, which is a device that converts pressure energy into mechanical motion. This type of motion can then control other components, such as a valve or a motor, with precision. The motors, in turn, can be used to perform automated tasks. Additionally, compressed air can also be used to create a vacuum or to blow out dust, dirt, and debris.

Hydraulics

Hydraulics refers to applications involving the use of liquids, such as oil or water. It can be used in high-pressure applications up to 700 bar, making it suitable for operating heavy machines in industrial settings. It is also often used for transferring power between locations, for example, driving a hydraulic motor from a pump located at a different location. Common applications include aircraft hydraulic systems, control systems, lifting and positioning systems, and cranes.

At the heart of a hydraulics system is a pump, which is responsible for pushing liquid through the system. The pump is usually supplemented with additional components, such as valves, filters, and accumulators. The liquid is then routed through a network of pipes, tubes, hoses, and fittings to the point of use, which may include a motor, a valve, or an actuator.

Once the liquid reaches the component, it is used to power a variety of functions. In some cases, it is used to drive a hydraulic motor, which converts energy from the liquid into mechanical motion. This type of motion can then be used to control other components, such as a valve or a cylinder with precision. Similarly, the fluid can be used to create a vacuum or to transfer power from one location to another.

The working principles of both pneumatics and hydraulics involve the use of air or liquid to transmit power from one location to another. A key advantage of both technologies is that they are relatively inexpensive and easy to install and maintain. Furthermore, both technologies are highly reliable and able to offer consistent performance even in harsh and demanding environments.
