The wire braided hose is a type of hydraulic hose that consists of an inner tube, one or more layers of wire reinforcement, and an outer cover. The wire reinforcement is designed to provide strength and stability to the hose, allowing it to withstand high pressure and resist kinking, twisting, and bending. However, over time, the wire layer may become damaged or even break, compromising the performance and safety of the hose.
Some common causes of wire layer fracture in wire braided hoses include:
Fatigue: The repeated bending, twisting, and stretching of the hose during use can cause the wire reinforcement to fatigue and eventually break. This is a common issue in hoses that are subject to frequent vibration, pressure pulsation, or other dynamic stresses.
Abrasion: The wire layer can also become damaged or worn due to abrasion from external factors such as rough surfaces, sharp edges, or contact with other objects. This is more likely to occur in hoses that are used in harsh or abrasive environments.
Corrosion: The wire layer of a hose can also corrode due to exposure to corrosive fluids, such as acids, alkalis, or saltwater. This can weaken the wire reinforcement and cause it to break over time.
Over-bending: Excessive bending or over-bending of the hose can cause the wire reinforcement to deform or break. This can occur if the hose is routed improperly or if it is subjected to repeated bending in the same location.
Overpressure: If the hose is exposed to pressure that exceeds its rated capacity, the wire layer may be deformed or even rupture, causing the hose to fail.
Ageing: Over time, the rubber material in the hose may degrade and become less flexible, which can cause the wire layer to break or lose its strength.
To prevent wire layer fracture in wire braided hoses, it is important to select a hose that is designed for the intended application and operating conditions. Proper routing, installation, and maintenance of the hose can also help to prevent premature wear and damage to the wire layer. Regular inspections and testing can also help to identify potential issues and prevent catastrophic failure of the hose.
