Working principle of hydraulic station

The working principle of hydraulic station (hydraulic power unit) is based on Pascal's law. It transmits power through the pressure energy of liquid and drives the actuator (such as cylinder, hydraulic motor) to complete mechanical action. The following is a brief description of its core working principle and components:

1. Basic working principle of hydraulic station

1.1 Pascal's law: In a closed liquid, the pressure applied to any point will be transmitted in all directions without changing its size.

1.2 Energy conversion: The motor/engine drives the hydraulic pump to convert mechanical energy into hydraulic energy (high-pressure oil). After adjustment by the control valve, it drives the actuator to do work and finally outputs mechanical motion (linear, rotational).

2. Core components and functions of hydraulic station

2.1 Power source: Motor/diesel engine, providing mechanical energy for the hydraulic pump.

2.2 Hydraulic pump: converts mechanical energy into hydraulic energy and outputs high-pressure oil (gear pump, plunger pump, etc., with a maximum pressure of 50MPa).

2.3 Control valve group: directional valve (reversing), pressure valve (overflow protection), flow valve (speed regulation), control the flow direction and pressure of oil.

2.4 Actuator: hydraulic cylinder (linear motion), hydraulic motor (rotary motion).

2.5 Oil tank: oil storage, heat dissipation, precipitation of impurities, usually equipped with oil level gauge and filter.

2.6 Auxiliary components: filter (oil purification), cooler (temperature control), accumulator (energy storage buffer), pressure gauge (monitoring).

3. Main application scope of hydraulic station

Hydraulic station has the advantages of simple structure, convenient operation, and efficient energy transmission, so it is widely used in many industrial fields. The following are some industrial application fields suitable for hydraulic station:

3.1 Construction machinery: Hydraulic station is widely used in various construction machinery such as cranes, excavators, loaders, bulldozers, rollers, etc. Through hydraulic transmission, these machines can complete various construction tasks more stably and efficiently.

3. 2 Metallurgical industry: Hydraulic stations also play an important role in metallurgical equipment such as turning machines, continuous casting machines, and rolling mills. Hydraulic stations can control the movement, force, and speed of equipment to ensure normal and efficient operation of the equipment.

3.3 Other industries: such as ships, new energy (such as wind power variable pitch systems).

Through customized design (such as variable pumps, smart sensors), hydraulic stations can adapt to complex working conditions and improve energy efficiency.
