hidràuliques

Hidràuliques, also known as hydraulic systems, are mechanical systems that use liquid to transmit power. They are widely used in various industries, including construction, manufacturing, and automotive, due to their ability to provide high force and precise control. The basic principle behind hydraulic systems is Pascal's law, which states that a pressure exerted on a confined fluid is transmitted undiminished throughout the fluid and acts with equal force on equal areas.

Hydraulic systems typically consist of a pump, control valves, actuators, and a reservoir. The pump generates pressure by forcing fluid into the system. Control valves regulate the flow and direction of the fluid, allowing for precise control of the system's operation. Actuators convert the fluid pressure into mechanical motion, such as linear or rotational movement. The reservoir stores excess fluid and helps maintain a constant supply.

Hydraulic systems offer several advantages, including high power-to-weight ratio, precise control, and the ability to operate in harsh environments. However, they also have some limitations, such as the potential for fluid leakage and the need for regular maintenance to prevent contamination and wear.

Hydraulic systems are classified into two main types: open-center and closed-center systems. Open-center systems have a common return line for all actuators, while closed-center systems have separate return lines for each actuator. The choice between these systems depends on the specific application and its requirements.

In summary, hidràuliques are versatile and powerful mechanical systems that use liquid to transmit power. They are widely used in various industries and offer numerous advantages, although they also have some limitations that must be considered. Understanding the basic principles and components of hydraulic systems is essential for their effective design, operation, and maintenance.
