What does hydraulics do?
Hydraulic technology is an engineering technology that uses liquid to transmit pressure and energy. It is widely used in industry, agriculture, aerospace, construction machinery and other fields. The hydraulic system transmits power through a closed liquid medium (usually oil) and has the characteristics of smooth transmission, high power density, and high control accuracy. This article will combine recent hot topics to analyze the role of hydraulic technology and its application scenarios, and attach structured data for reference.
1. Basic principles of hydraulic technology
The hydraulic system mainly consists of hydraulic pumps, hydraulic cylinders, control valves and hydraulic oil. Its core principle is Pascal's law, which states that pressure in a closed liquid can be transmitted uniformly. The mechanical energy is converted into hydraulic energy through the hydraulic pump, and the hydraulic energy is converted into mechanical energy through the hydraulic cylinder, thereby achieving force amplification or motion control.
