About hydraulic hose

Hydraulic hose mainly by the resistance within the liquid layer, middle layer, layer 2 or 4 or 6 wire spiral reinforced layer, outer layer, inner layer having the conveying medium under pressure, the protective effect of the wire from erosion, an outer layer to protect wire from damage, wire reinforcing material layer is from enhancement is mainly used for mine hydraulic support, oil exploration, suitable for construction, lifting transport, forging metallurgy, mining equipment, ships, injection molding machinery, agricultural machinery , machine tools and various industrial sectors mechanization and automation of hydraulic transmission system has a certain pressure (high pressure) and a temperature of petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel, lubricants) and water-based liquids (such as emulsion, oil-water emulsion, water) and liquid transmission with a maximum pressure resistance of up to 60MPa.

 Hydraulic hose in use should note the following:

1. the bending radius of the hose should not be too small, and the connection hose assembly fittings should have a straight part of this length should not be less than twice the pipe diameter.

2. Hydraulic hose assembly should take into account the length of hose after a pass into the oil pressure, the length of the shrinkage occurs, generally the amount of shrinkage of 3 to 4% of the tube length. Therefore, when installation hose assembly is not allowed under tension.

3. Hydraulic hose assembly should be installed to ensure that no torsional deformation. Hose joint axis should be placed in the plane of motion, to avoid damage to the hose ends of each movement.

4. Hydraulic hose should avoid contact with sharp parts on mechanical friction and to avoid damage to the pipe.
