Hydraulic Unit Materials

Various parts and elements that constitute the basic components of a hydraulic system and ensure the efficient operation of the system. A hydraulic unit is a device designed to transmit energy using fluid power, move machine parts, or perform mechanical work, usually using hydraulic fluids.

These units are necessary for machines and industrial equipment that operate with high-pressure fluids. A hydraulic unit consists of various materials and components, and these materials help ensure that the system is safe, efficient, and long-lasting.

1. Hydraulic Pump

The hydraulic pump is considered the heart of the hydraulic system. It provides the capacity for work in the hydraulic system by pumping fluid, usually special hydraulic fluids like oil, under high pressure. There are various types:

• Diaphragm Pump: Transports liquid through a diaphragm. Typically used in small, low-pressure systems.

• External Gear Pump: A type of pump that pumps liquid with gear wheels, efficient and reliable.

• Piston Pump: Suitable for applications with high pressure requirements and very powerful.

2. Hydraulic Motor

The hydraulic motor converts hydraulic fluid into mechanical energy. While hydraulic pumps send fluid under pressure, motors use this pressure to provide rotary or linear motion. Hydraulic motors are typically found in the following types:

• Piston Motors: Provide high torque and efficiency, preferred for large applications.

• Gear Motors: Operate at lower torque and speed, but their costs are generally lower.

3. Hydraulic Valves

Hydraulic valves are devices that direct the flow of fluid, control its pressure, and adjust the flow rate. These elements are crucial for managing the flow of fluid in the hydraulic unit.

• Directional Control Valves: Determine the flow direction. These valves direct the fluid in the desired direction.

• Pressure Control Valves: Release excess pressure in the system and provide the optimum operating pressure.

• Flow Control Valves: Adjust the fluid flow rate.

4. Hydraulic Accumulators

Accumulators store pressurized fluid and balance the system by releasing fluid when needed. Accumulators are used to meet sudden power demands, balance pressure fluctuations, and increase energy efficiency.

• Carbon Dioxide Accumulators: Generally used in low and medium-pressure systems.

• Diaphragm Accumulators: Balance the pressure difference between compressed gas and liquid.

5. Hydraulic Tanks and Storage Units

Hydraulic tanks are used to store fluid in the system and maintain the fluid level at a specific level. These tanks also function to cool the fluid and prevent the accumulation of contaminants.

• Pressurized Tanks: Maintain the fluid at a certain pressure in the system.

• Open Tanks: Non-pressurized tanks commonly used in open systems.

6. Pipes and Hoses

Pipes and hoses are used to transmit fluid in the hydraulic system. These components are necessary for pumping fluid, directing it to motors and other components. Pipes are generally made of stainless steel or materials resistant to high pressure, while hoses are more flexible and used to attach to moving parts of the system.

• Stainless Steel Pipes: Resistant to high pressure and long-lasting.

• Hydraulic Hoses: Used for flexibility and movable connections.

7. Filters and Cleaning Systems

Filters clean dirt and foreign matter from the hydraulic fluid. These elements are critical for increasing system efficiency, preventing wear, and ensuring the system's longevity. Filters typically include:

• Oil Filters: Clean solid particles in the liquid.

• Water and Air Separators: Remove water and air mixed in the hydraulic fluid.

8. Connection Elements and Fittings

Connection elements ensure safe connection of hydraulic pipes and hoses to other components of the system. These elements prevent fluid leaks and contribute to the proper operation of the system.

• Clamps: Used to secure pipes and hoses.

• Male and Female Fittings: Allow pipes to be connected to each other at connection points.

9. Control Panels and Electrical Components

Control panels are used to monitor and adjust the operational parameters of the hydraulic system. Electrical components control motors, pumps, and valves in the system. These panels commonly include:

• Pressure Gauges: Monitor system pressure.

• Flow Meters: Control fluid flow rate.

• Emergency Stop Buttons: Used to safely shut down the system.
