Hydraulic Unit Materials

Hydraulic units are systems that work by directing fluids under pressure. These units are used in a wide range of applications from industrial machines to automotive systems. It is crucial to use the right materials for hydraulic units to operate efficiently. These materials should be selected to ensure the safety, durability, and efficiency of the system.

Hydraulic Unit Materials: Overview

A hydraulic unit consists of various components used to control, direct, and convert the pressured fluids into power. The materials used for these systems must be resistant to high pressure and challenging working conditions. The main materials used in hydraulic units include pumps, valves, hoses, cylinders, filters, and oils.

1. Hydraulic Pump

Hydraulic pumps are components that move fluid under pressure and convert energy into mechanical work. These pumps maintain the fluid in the system at a specific pressure to provide hydraulic power.

• Applications: Industrial machinery, construction equipment, automotive hydraulic systems.

• Material Properties: They require high durability and wear resistance. They are commonly made from steel and cast iron.

2. Hydraulic Valves

Hydraulic valves control the direction, speed, and pressure of fluids. These valves ensure the correct flow of hydraulic fluid and the efficient operation of the system.

• Applications: Industrial automation, automotive, heavy machinery.

• Material Properties: Valves are usually made from high-pressure resistant steel alloys and equipped with seals that provide leak-tightness.

3. Hydraulic Cylinders

Hydraulic cylinders convert hydraulic energy into linear motion. The fluid is pumped into the cylinder to move the pistons, and this movement is transmitted outward.

• Applications: Various industrial machines, construction equipment, vehicles.

• Material Properties: Cylindrical structures are generally made of steel. Durable alloys and sealing elements are required for pistons.

4. Hydraulic Hoses and Pipes

Hydraulic hoses carry the fluid in the system and are usually designed to withstand high pressure. Hoses are made of flexible and durable materials. Pipes, on the other hand, transport fluid through fixed lines.

• Applications: All hydraulic systems, especially heavy machinery.

• Material Properties: Materials such as steel, stainless steel, and rubber, which are durable, are commonly used. They must be resistant to high pressure and flexible.

5. Hydraulic Filters

Filters remove dirt, rust, and other foreign particles from hydraulic systems to ensure smooth operation. Dirty fluid can damage system components, making filters essential.

• Applications: All hydraulic systems, especially those that require long-term operation.

• Material Properties: Filter elements are usually made of metal or high-quality synthetic materials. They must be highly efficient and long-lasting.

6. Hydraulic Oils and Fluids

Hydraulic oils are used as a substance that allows fluids to move under pressure and prevents system wear. Additionally, oils provide cooling and sealing functions.

• Applications: All hydraulic systems, especially machines and heavy equipment.

• Material Properties: The viscosity, temperature resistance, and anti-wear properties of oils are crucial. Generally, mineral oils, synthetic oils, or biodegradable oils are used.

7. Hydraulic Seals

Seals are used to provide leak-tightness for hydraulic systems. These components ensure that the fluid moves only in the desired paths and does not leak outside.

• Applications: All hydraulic systems.

• Material Properties: They are generally made of rubber, rubber, PTFE, or metal alloys. They must be resistant to high temperatures and pressures.

8. Hydraulic Tanks

Tanks provide storage for hydraulic fluids and ensure smooth flow in the system. These units monitor fluid levels and store excess fluid.

• Applications: Industrial machinery, construction equipment, automotive sector.

• Material Properties: They are generally made of metal alloys, with emphasis on sealing and safety.

9. Hydraulic Assembly and Connection Elements

Assembly elements ensure that all components are connected. These elements ensure that the connections in the system are safe and durable.

• Applications: All hydraulic systems.

• Material Properties: Durable materials such as steel, stainless steel, or aluminum are used.

Features of Hydraulic Unit Materials

Hydraulic unit materials must be resistant to challenging conditions such as high pressure, wear, corrosion, and high temperatures. The main features that these materials must have are as follows:

• High Durability: Hydraulic systems generally operate under challenging conditions, so the materials used must be durable.

• Wear Resistance: Components like pumps, valves, and hoses are in constant motion, so they need to be resistant to wear.

• Corrosion Resistance: In moist environments, materials such as stainless steel or coatings are used to prevent corrosion.

• Heat Resistance: Hydraulic fluids can be subjected to high temperatures, so materials must be heat resistant.

• Flexibility and Sealability: Components like hoses and seals must be flexible and designed to prevent leaks.
