Where do you use a pneumatic hose
How does compressed pneumatic hose work?
Pneumatic hoses are often used in compressors and conveyor oils. Condensate, dust particles, etc. So the material of the pneumatic hose must be resistant to all the above substances,
The usual pneumatic hose is a single layer, which means it is produced from a material that needs to be chemically resistant to compressor oil and other media, while being protected from any environmental conditions.
In addition to one layer of pneumatic hose, there are three layers of pneumatic hose to ensure that the internal hose material is resistant to compressor oil and condensate, reinforced with polyester braided wire in the middle, and then the outer layer is also an outer rubber layer.
Most pneumatic hoses are made of thermoplastics. As mentioned above, depending on the application, they can be single-layer or multi-layer, of which the most commonly used are polyurethane and polyamide materials:
Polyurethane (PUR or PU): resistant to kinking and abrasion, with strong flexibility.
Polyamide (PA or nylon): light weight, strong, dimensional stability, good bending radius, good bending fatigue resistance, low moisture absorption rate.
The pneumatic hose reel is a cylindrical main shaft for storing hoses. Usually, they are installed on a wall, ceiling or floor. They help to keep hoses organized and avoid kinks. Normally, they are automatically retracted by a spring drive mechanism, but they can also be turned manually. Generally, pneumatic hose reels are used in conjunction with pneumatic tools, or any other application that only requires temporary supply of compressed air.
Coiled pneumatic hoses are commonly used in garages and workshops to supply air to pneumatic tools (such as impact wrenches, blow guns, etc.). They are lightweight and automatically expandable, so they don’t take up much space. The hose does not usually wrap all the way to the joint. A small straight part is left on both sides, called the tail. The difference between the extended and retracted length depends on the coil diameter. For a standard coiled air hose, the extension length may be, for example, ten times the retracted length. In order to produce coiled air hoses, the hose material needs to have good elastic memory to restore its original coiled form after straightening. Nylon and PU are usually used for these applications.
