Hydraulic circuit components are the basic elements used in hydraulic systems where fluids move under pressure and are converted into mechanical energy. These components enable the effective and safe use of hydraulic power. In a hydraulic system, there are many different components that direct fluid flow, control pressure levels, transmit power, and perform mechanical operations. In this article, we will examine hydraulic circuit components and how they work in detail.

1. Hydraulic Pumps

Hydraulic pumps are the main components that move fluid under pressure in hydraulic circuits. The pump converts mechanical energy into fluid, initiating fluid flow and activating the system.

• Areas of Use: Construction machinery, industrial automation systems, mobile machinery.

• Material Characteristics: High durability, wear resistance, and usually made of steel materials.

• Operating Principle: The hydraulic pump draws fluid through a rotor or piston driven by a shaft and delivers it to the outlet.

2. Hydraulic Valves

Hydraulic valves are elements that direct and control fluid flow. These valves regulate the direction, speed, and pressure of fluid flow, ensuring the proper functioning of functions in the system.

• Areas of Use: Automotive sector, production machinery, construction equipment.

• Material Characteristics: Steel, aluminum, and stainless steel materials are preferred.

• Types:

  • Directional Control Valves: Changes the flow direction.

  • Pressure Control Valves: Controls the pressure in the system.

  • Flow Control Valves: Adjusts the flow rate.

3. Hydraulic Cylinders

Hydraulic cylinders are used to convert hydraulic fluid into linear motion. Through pistons, the pressure of the fluid is converted into mechanical motion energy.

• Areas of Use: Automotive, robotic systems, heavy machinery.

• Material Characteristics: High-pressure resistant steel alloys, stainless steel, and sturdy sealing elements.

• Operating Principle: The fluid moves the piston of the cylinder to generate linear force.

4. Hydraulic Hoses and Pipes

Hydraulic hoses and pipes facilitate the transportation of fluids within hydraulic circuits. Hoses are flexible, while pipes are used for more rigid and fixed connections.

• Areas of Use: All hydraulic systems, especially applications requiring high flexibility.

• Material Characteristics: High-pressure resistant materials such as stainless steel, rubber, and polyurethane.

• Operating Principle: The fluid is transported from one component to another through a hose or pipe.

5. Hydraulic Tanks

Hydraulic tanks store hydraulic fluids. These tanks maintain the necessary fluid levels for the system to function properly.

• Areas of Use: Industrial machinery, automotive, construction machinery.

• Material Characteristics: Typically made of stainless steel or aluminum.

• Operating Principle: The fluid is accumulated in the tank and is delivered to the system through pumps when needed.

6. Hydraulic Filters

Hydraulic filters clean hydraulic fluids from dirt and foreign particles. Filtration extends the life of components in the system and increases efficiency.

• Areas of Use: All hydraulic systems, especially under heavy-duty conditions.

• Material Characteristics: Metal and high-quality synthetic materials.

• Operating Principle: Contaminated fluid passes through filter elements to be cleaned.

7. Hydraulic Seals

Hydraulic seals are used to provide sealing for fluids. These elements ensure that the fluid flows correctly and does not leak out.

• Areas of Use: All hydraulic systems, especially systems with high-pressure requirements.

• Material Characteristics: Flexible and durable materials such as rubber, PTFE (polytetrafluoroethylene).

• Operating Principle: Seals prevent liquid leakage at connection points or moving parts.

8. Hydraulic Auxiliary Components

These elements ensure the more efficient operation of hydraulic circuits. These include pressure regulators, timers, and converters.

• Areas of Use: Automation systems, industrial machinery, robotic applications.

• Material Characteristics: Steel and aluminum alloys.

• Operating Principle: These elements provide auxiliary functions to other components in the system, such as stabilizing pressure or regulating fluid flow.

9. Hydraulic Connection Elements

Connection elements ensure the safe connection of all components in a hydraulic system. These can be flanges, fittings, and connectors.

• Areas of Use: All hydraulic systems, especially when secure connections between components are required.

• Material Characteristics: Steel, stainless steel, and aluminum.

• Operating Principle: These elements ensure the leak-free flow of hydraulic fluids.

10. Hydraulic Power Units (Motors)

Hydraulic motors convert the fluid from hydraulic systems into mechanical energy. These motors enable machine operation by generating rotational movement.

• Areas of Use: Various industrial machinery, vehicles, equipment.

• Material Characteristics: Made of steel and cast iron with high durability and low wear properties.

• Operating Principle: The fluid is converted into rotational movement in the motor.
