    1、 Hydraulic principle
    Hydraulic press is a transmission method that uses liquid pressure to transfer energy. In a hydraulic press, mineral oil or other liquids are pressed into one or more cylinders of the machine, and then generate force and motion through compression and expansion. The hydraulic principle of a hydraulic press is to solve dynamic problems in fluid mechanics, such as the fluid momentum theorem, continuity equation, and Bernoulli's theorem.
    2、 Hydraulic components
    The hydraulic components in hydraulic presses are mainly composed of oil pumps, oil tanks, high-pressure pipelines, directional control valves, actuators, etc. Among them, the oil pump is used to generate pressure, the oil tank is used to store liquid, the high-pressure pipeline is used to transmit liquid, the directional control valve is used to control the direction of movement of the hydraulic press, and the actuator is used for power output.
    3、 Control system
    The control system of hydraulic press mainly includes electronic control system, mechanical control system, and hydraulic control system. The electronic control system can achieve automated control, the mechanical control system can achieve simple manual control, and the hydraulic control system can achieve correct motion and force control. The control system of hydraulic press needs to choose the appropriate control method according to different application scenarios.
    4、 Application Fields
    Hydraulic presses are widely used in fields such as mechanical processing, metallurgy and mining, construction engineering, automotive maintenance, water conservancy and power. In the field of mechanical processing, hydraulic presses can be used for operations such as pressing, drilling, stretching, and forming; In the field of construction engineering, hydraulic presses can be used for operations such as lifting, pushing, pulling, and positioning; In the field of automobile maintenance, hydraulic presses can be used for operations such as compressing springs and striking wheels.
