What is Hydraulis Hose

Hydraulic hose is designed specially to transfer hydraulic fluid to or among hydraulic valves, actuators, components, and tools. It is typically flexible and often reinforced. A hydraulic hose consists of an inner tube through which the fluid is conveyed and comes into direct contact with the hydraulic fluid. The rubber or other synthetic material used for this needs to be compatible and able to withstand the range of working temperature without losing its chemical and physical stability.

Hydraulic Hose Materials

The hydraulic hoses can be made using a variety of materials, depending on the factors of oil compatibility, abrasion resistance etc. These include:

Plastic: The plastic materials comprise of: Nylon, Braided nylon hose , Polyvinyl chloride, Textile braided hoses, Thermoplasts, Teflon, Chloro sulfonated polyethylene (Hypalon), Ethylene propylene diene (EPDM), Chlorinated polyethylene etc.

Homogeneous Synthetic Rubber: This category includes hose materials like: Buna N, Neoprene, Natural rubber, Butyl etc.

Hydraulic Hose Construction

Hydraulic hose comprises three main parts

• An inner tube: The inner tube carries the fluid. It should be flexible and needs to be compatible with the type of fluid it will carry. The tube is usually made of the materials as mentioned above.
• A reinforcement layer: The reinforcement layer consists of one or more sheaths of braided wire, spiral-wound wire, or textile yarn.
• A protective outer layer:The outer layer is often oil, weather and abrasion-resistant. This depends on the type of environment the hose is designed for.

Hydraulic Hose Selection Tips

All hydraulic hoses have a finite life. That is why it is necessary to select the proper sizing and the correct type of hose as per the application area and this will certainly extend the life of a hose assembly. Besides this, there are other factors to consider as well. Check out our article Tips to Select Hydraulic Hose

Maintenance Tips of Hydraulic Hose

The hydraulic hose is an important element in the system that needs to be checked for its reliability and durability during the manufacture process. In many hydraulic systems, it is necessary to move the drive unit along with the oil lines. The hydraulic hoses need frequent maintenance that facilitates smooth working thereby increasing their service life. Some important considerations are:

1. The excessive taut in the connected hose should be avoided while connecting two elements through a hose.
2. When pressure is applied to hose, the hose tends to bulge and decrease in length. Thus slackness needs to be permitted to avoid strain to the hose.
3. They should not be installed with a twisting as it may weaken the hose structurally and cause loosening of the fittings.
4. High temperature may damage the hose cover and may shorten its useful life. Hence under hot working conditions, the hoses should be protected through proper heat insulation by using heat resistant hose material.
5. The hose run should be such that rubbing and abrasion with the metal members of the system are avoided. Clamps and hose guards are often used to group the hoses and keep them away from the moving parts.
6. The hose manufacturer's guidance and specific instructions need to be taken care of with regard to bend radius, environment and oil' compatibility, pressure capability, etc.
