Introduction to Hydraulic Hoses
A hydraulic hose is synthetic rubber that carries high-pressure fluid to transmit force in a hydraulic machine and allows the system to work as its meant to. As most technological occurrences, hydraulics spurred in the industrial age, and along with this, hydraulic hoses came about.
There are three main parts that make up construction hydraulic hoses.
- An inner tube that carries fluid
- A sheath of braided wire, spiral wound wire, a textile based yarn, then reinforces the inner tube
- And thirdly, a protective outer layer that provides protection from weather, abrasion, oil or chemicals.
Hydraulic hoses are designed for use in hydraulic mechanical applications, or fluid transfer. Hydraulic hoses are designed to be specific sizes and lengths, and have custom connectors to work in different machines.
Hydraulic systems can transmit force effortlessly by transmitting liquid or gas from a force engine to its destination simply by stringing hydraulic hoses between the two. Variations in size of hoses can increase or decrease the force applied.
Advantages of hydraulic hoses are that they turn forces from a few ounces of pressure into hundreds of tons of output. Using hydraulic machines and hydraulic hoses creates a very powerful torque at low speed, manage speed and movement of machines with high accuracy. A single hydraulic pump can power many different machines and machine functions at widely varying power levels at the same time, all through hydraulic hoses. Hydraulic powered machines can also operate safely in areas where there are flammable vapors and electrical devices.
Every hose has specific ratings for specific types of fluid they are designed to carry. The working temperature ranges and thus, different pressure limits for each specific hose. Usually, each temperature and pressure limit is printed on the hose or fitting. In some cases, manufacturers print a model number on the hose and provide a specification sheet explaining the specifications of that specific hose and other models the manufacturer produces.
It’s important to stay cautious of hydraulic systems as they operate under high pressures. They should also be checked and replaced according to the manufacturers recommendation.
