Slide Gate Hydraulic Hose
To transfer energy-generating liquid between different components to form a complete hydraulic circuit. Pipes and tubes can be rigid in order to bridge small amounts of space in a controlled manner. For instance, in a hydraulic circuit contained within a small casing, there is no extra room for piping, so the connections must be rigid and contained within the casing. Some hydraulic circuits have much more liberal space accommodations or even require connection flexibility to facilitate faster replacement or range of motion operations. For example, many construction machines have external, flexible hydraulic hose connections so the tools are free to move.
A number of standards exist for hydraulic hose production and use. Standards govern industry connection specifications and hose material, as well as guide installation operations.
Basic Slide Gate Hydraulic Hose Construction
The basic construction involves three layers. These layers help maintain a consistent and reliable flow of liquid while protecting the overall assembly from breaking down as a result of wear or abrasion.
- Inner tube: The inner tube is designed to be compatible with the liquid it carries, allowing both free-flowing elasticity and pressure-resistant stress bearing. This tube is often made from PDFE (PTFE), thermoplastic, or synthetic rubbers.
- Reinforcement layer: This layer surrounds the inner tube and is composed of a coiled or braided wire. This set up supports the tubing while protecting against tears.
- Outer layer: This layer is made of rigid materials and is designed to protect the innards of the hose.
Types of Slide Gate Hydraulic Hose Construction
Due to the variety of hydraulic hose applications and the range of chemicals and pressures they will be subjected to, there are likewise a number of hydraulic hose constructions.
- Reinforced: This type of hosing resembles the basic three-layer construction, but with extra buffers in the reinforcement layer, most often in the form of textile braid, wire braid, or wire helix material around the inner tube.
- Coiled: Coiled hoses are semi-rigid hoses designed for expansion and easy storing. Because the hose is coiled, it can stretch in such a way that does not put unnecessary pressure on the hose materials.
- Corrugated: Another method of increasing expansion and flexibility in a hose is to introduce corrugation. Corrugation manifests as small threads or folds in the material of the hose, somewhat like an accordion, that allow the hose to expand and compress without damaging the housing.
- Articulated: Articulated hoses are hoses built in sections, with rigid shafts connected by flexible joints. The articulation allows hoses to turn corners or swivel around other components.
- Multi-element: Hoses that involve multiple elements listed above are termed “multi-element hoses.”
Hydraulic Hose Compatibility: Temperature upto 1200 deg. Cent.
Hydraulic hoses are exposed to two temperature concerns: internal liquid temperature and external working temperature. As a result, hoses are rated for performance in terms of both temperatures, with a maximum and minimum functioning temperature rating. Exceeding these ratings can result in severely reduced working life or even failure, so it is pertinent to use a hose that is properly rated to both the liquid temperature and the environment temperature.
Hydraulic Hose Compatibility: Pressure
Hydraulic hoses are designed to withstand both an external and an internal pressure minimum and maximum. Exceeding either of these ratings can severely curtail hose performance. Pressure ratings or recommendations for a specific type of hose are generally available from the manufacturer.
