Standard hydraulic transmission system composition and working principle

The standard hydraulic transmission system includes components such as hydraulic pump, flow control valve, pressure control valve, hydraulic cylinder, and oil tank.

Hydraulic pump: converts input mechanical energy into hydraulic energy.
Flow control valve: used to control the inlet and outlet of liquid in hydraulic systems, as well as the magnitude of flow rate.
Pressure control valve: used to control the pressure level of the liquid in the hydraulic system to ensure system stability.
Hydraulic cylinder: converts hydraulic energy into mechanical energy, or vice versa, converts mechanical energy into hydraulic energy.
Oil tank: used to store liquids in hydraulic systems.

The basic working principle of hydraulic transmission system is to use pressure to transfer liquid (usually oil) through pipelines. By controlling various related components in the hydraulic system (such as hydraulic pumps, flow control valves, pressure control valves, hydraulic cylinders, etc.), energy is transmitted and converted to achieve mechanical movement and force control in different working parts. The working process is as follows: when the hydraulic pump is started, the liquid is sucked into the hydraulic pump and controlled to flow into the pressure control valve through pressure, further controlling the pressure of the liquid. Then, the liquid is controlled by a flow control valve to control the flow rate and flow to the hydraulic cylinder, thereby driving mechanical movement. The advantage of hydraulic transmission systems is that the output force and speed can be quickly adjusted to meet the needs of different working environments.
