Spiral Hydraulic Hose
This type of hydraulic hose consists of multiple layers of spirally-wrapped steel wire, which provides increased support and reinforcement to the hose. Spiral hydraulic hoses are typically used in high-pressure applications.
Multi-Spiral Hydraulic Hose
This type of hydraulic hose consists of multiple layers of spirally-wrapped steel wire, which provides even greater support and reinforcement to the hose. Multi-spiral hydraulic hoses are typically used in very high-pressure applications.
Application of Hydraulic Hose
Hydraulic Systems
Hydraulic hoses are extensively used in hydraulic systems to transmit hydraulic fluid under high pressure. These systems are commonly found in construction equipment, agricultural machinery, industrial machinery, and transportation vehicles.
Heavy Machinery and Equipment
Hydraulic hoses play a crucial role in heavy machinery and equipment, such as excavators, loaders, cranes, forklifts, and bulldozers. They are used to control and transmit hydraulic power for various functions like lifting, digging, steering, and braking.
Industrial Machinery
Hydraulic hoses are used in various industrial applications, including manufacturing machinery, power generation equipment, presses, machine tools, and robotics. They enable precise control and efficient transmission of hydraulic power in these systems.
Automotive and Transportation
Hydraulic hoses are used in automotive applications, particularly in braking systems and power steering systems. They help transmit hydraulic pressure to control braking force and assist in steering movements.
Aerospace and Aviation
Hydraulic hoses are utilized in aircraft and aerospace systems, such as landing gears, control surfaces, and hydraulic actuators. These hoses ensure reliable transmission of hydraulic power for critical functions in the aviation industry.
Marine and Offshore Applications
Hydraulic hoses are used in marine environments, including shipbuilding, offshore drilling platforms, and hydraulic winches. They withstand harsh conditions and transmit power for various marine operations.
The Materials Used In Making Hydraulic Hoses
Most hydraulic hoses are made from rubber, either synthetic or natural. Rubber offers excellent flexibility, durability, and resistance to abrasion and chemicals. It is also easy to mold and shape into different sizes and shapes.
Thermoplastic materials, such as nylon, polyurethane, and PVC, are increasingly being used in hydraulic hoses. These materials offer high resistance to abrasion, chemicals, and temperature changes. They are also lightweight, flexible, and easy to install.
Teflon is a synthetic material that offers excellent resistance to chemicals, high temperatures, and corrosion. Teflon hydraulic hoses are commonly used in applications involving aggressive chemicals or extreme temperatures.
Metal hoses, made of stainless steel or other alloys, are used in applications that require high-pressure and high-temperature resistance. They are also used in applications that require resistance to abrasion, vibration, and shock.
Composite hydraulic hoses are made of a combination of materials, such as rubber, thermoplastics, and metal, to offer a balance of properties such as flexibility, strength, and resistance to abrasion and chemicals.
Material
The material of the hydraulic hose should have chemical compatibility with the hydraulic fluid coming in contact with it. The hose is generally made up of synthetic rubber, like NBR (nitrile), EPDM (ethylene propylene diene monomer), and SBR (styrene-butadiene rubber). However, they can also be thermoplastics, Teflon, or silicone. Synthetic rubber hoses are suitable to use with hydraulic oils.
Pressure
The hydraulic hose must be able to withstand the maximum working pressure, including pressure spikes that may occur during the operation.
Temperature
The hydraulic hose should be able to work comfortably in a defined temperature range. Exposure to high temperatures for a long time can cause the hose to lose its flexibility. A high-temperature hydraulic hose should be used for such applications.
Length
The hose length should be enough to allow for bending and flexing during the movement of the machinery parts.
Diameter
The inside diameter of the hose should be compatible with the fluid flow rate for the application. The smaller the diameter, the higher the velocity. This high velocity will cause excess heat, friction, and turbulence in the system.
Bending radius
A bending radius is a minimum radius that a looped hose can achieve without causing any damage to the hose. Bending should not occur at the start of the hose end fitting because this might result in leaks at the hose fitting. Tight bends can increase the turbulence of the hydraulic fluid which can damage the inner layer of the hose.
Reinforcement
The reinforcements can be helical, spiral, or braided design. Helical design is best for suction application and spiral design for extreme high-pressure applications. A braided design is best used for a low or moderately high-pressure application.
End connection
Depending upon your requirement, hydraulic hoses are available with pre-made fittings for fast and easy connection, or without fittings for easy customization according to your application. For pre-made fittings, it is important to ensure the correct size fittings for compatibility with your system.
Accessories
The hoses need to be equipped with specialized hydraulic accessories to make sure they can fit on the pumps/actuators. Hydraulic hose clamps and hydraulic hose crimpers are used to ensure the hose is properly connected to the fittings and are crimped to the exact diameter. The fittings used should be specifically designed for the hydraulic application, with the ability to withstand high pressure. A hydraulic hose cutter can be used to ensure the perfect length of the hose for the application.
Process of Hydraulic Hose
According to the formula, the inner rubber layer, the middle rubber layer and the outer rubber layer of the wound hydraulic pipe are prepared by using a kneading machine; and the inner oil pipe is extruded and coated on the soft core coated with the release agent by using the extrusion equipment. Or on the hard core, but be careful not to use the die when using liquid nitrogen freezing.
Pressing the pad of the middle layer of rubber with a calender, then adding a release agent to wind up and cutting into a prescribed width according to the requirements of the winding hydraulic pipe manufacturing process.
Then, the inner tubing containing the die is wound on the winding machine or the braiding machine for copper-plated steel wire or copper-plated steel wire rope.
Next, the outer layer of rubber is coated on the extruder and then wrapped with lead or a vulcanized protective layer.
This step is mainly to carry out the necessary vulcanization by winding the hydraulic pipe through a vulcanization tank or a salt bath.
Afterwards, the vulcanized protective layer of the wound hydraulic pipe is removed, and then the core is taken out, and the pipe joint is buckled, and then the sampling and pressing test can be performed.
How to Maintain Hydraulic Hose
Regular Inspection
Inspect hydraulic hoses regularly to check for signs of wear, damage, or leaks. Hoses that show signs of wear or damage should be replaced immediately.
Proper Installation
Properly install hydraulic hoses to prevent them from being over-stressed, bent or twisted. Follow the manufacturer's instructions when installing hydraulic hoses.
Correct Routing
Route hydraulic hoses correctly to prevent them from being pinched or crushed. Keep hoses away from sharp edges, hot surfaces, or other potential hazards.
Cleanliness
Keep hydraulic hoses clean and free from debris to prevent contamination. Dirty hoses can cause damage to hydraulic systems and decrease the efficiency of the equipment.
Proper Storage
Properly store hydraulic hoses when not in use to prevent damage from sunlight, heat, or moisture. Hoses should be stored in a cool, dry place.
Operating Temperature
Make sure hydraulic hoses are operating within their specified temperature range. Excessive heat can cause hoses to weaken or burst, while too low temperatures can cause the hoses to become stiff and brittle.
Replacement Schedule
Develop a replacement schedule for hydraulic hoses based on their usage and the manufacturer's recommendations. Replacing hoses regularly can help prevent unexpected downtime and costly repairs.
5 Ways to Lengthen Your Hydraulic Hose Lifespan
Ensure the hose is not pulled too tight and that there a no kinks/knots
This is usually due to poor installation, and can cause structural weakness but can be easily avoided if fitted correctly.
Abrasion
Physical external damage is the most common cause of hose failure. Ensuring the hoses are not rubbing against each other or surrounding surfaces will help increase its lifespan.
Protection
Adding a hose guard, hose cover, hose sleeve or hose shield can prove beneficial to protecting the hydraulic hose from abrasion, flames and movement. Our hose protection equipment is designed to provide reliability and long-lasting protection for not only the hose but also for operatives as hose sleeves hold the energy of any potential bursts.
