Hydraulic Hose is an indispensable component of modern industrial and mechanical systems used in a wide range of applications including construction, agriculture, manufacturing, and automotive. Choosing the right Hydraulic Hose is critical because it directly affects the efficiency, durability, and safety of your system. So what is Hydraulic Hose? What is it made of? And what types are available? In this article, we'll take an in-depth look at Hydraulic Hose as a product to help you better understand how to choose the right Hydraulic Hose.
Hydraulic Hose is a flexible pipe used in hydraulic systems to transmit liquid power, such as oil, water, or other hydraulic fluids. It can work reliably under high pressure, high flow and dynamic movement conditions, and is an important part of the hydraulic system in construction machinery, industrial equipment, automobiles and other fields.
Inner layer (inner rubber layer)
Made of oil- and corrosion-resistant synthetic rubber (e.g., nitrile rubber, hydrogenated nitrile rubber) to ensure compatibility with hydraulic fluids.
Reinforcement Layer
Braided/twisted layer: Usually made of high-strength steel wires, polyester fibers or aramid fibers, providing resistance to compression and bursting.
Intermediate Adhesive Layer
Bonds each reinforcing layer to improve integrity.
Outer layer (outer adhesive layer)
Made of abrasion-, UV- and weather-resistant rubber or synthetic material to protect the hose from external environmental damage.
Features
High pressure resistance: can withstand pressures of several megapascals (MPa) to hundreds of MPa.
Flexibility: Adapts to equipment movement (e.g., bending and twisting of excavator arms).
Temperature resistance: Typically stable in the range of -40°C to +120°C.
Pulse resistance: withstands pressure fluctuations and vibrations in hydraulic systems.
Engineering machinery
excavator, loader hydraulic arm, cylinder connection.
Industrial equipment
injection molding machine, machine tool hydraulic power transmission.
Transportation
truck brake system, aircraft landing gear hydraulic control.
Agricultural machinery
hydraulic drive components of tractors, harvesters.
Pressure rating: Need to match the maximum working pressure of the system, and consider the safety factor (usually 4:1).
Fluid compatibility: Ensure that the inner material does not react chemically with hydraulic oil and additives.
Temperature range: Extreme environments require the selection of special materials (such as high-temperature resistant fluoroelastomer).
Bend radius: Avoid excessive bending of the hose leading to damage.
Certification standards: such as SAE (Society of Automotive Engineers), ISO, DIN and other certifications.
Periodic inspection: Observe surfaces for cracks, bulges, and leaks.
Avoid friction: Use sheaths or brackets to prevent friction with metal parts.
Lifespan Limit: Usually 5-10 years, but the actual lifespan is affected by the conditions of use and needs to be replaced immediately when signs of aging appear.
Deterioration: Hardened and cracked rubber.
Improper installation: excessive bending or twisting.
Pressure shock: Instantaneous overpressurization leading to bursting.
Contamination: Particles abrade the inner wall.
Hydraulic Hose is the “blood vessel” of the hydraulic system, and its reliability directly affects the safety and efficiency of the equipment. Correct selection, installation and maintenance can significantly extend service life and reduce the risk of failure.
Hydraulic Hose plays an indispensable role in industrial and mechanical applications, and is available in a wide range of materials, types and applications to meet the needs of different operating conditions. Choosing the right Hydraulic Hose not only improves the efficiency of your system, but also extends the life of your equipment and ensures safety on the job.
