Description

Technical Field

[0001] The invention belongs to the technical field of water hose testing, and in particular relates to wear resistance testing equipment for water hose production. Background Art

[0002] Fire hose is one of the important equipment used for fire fighting. Fire hose is a hose used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses are lined with rubber and wrapped with linen braid on the outer surface. They are usually made of soft rubber, synthetic rubber or plastic, and have high pressure resistance and wear resistance. Advanced fire hoses are made of composite materials such as polyurethane. There are metal joints at both ends of the fire hose, which can be connected to another hose to extend the distance or connected to a nozzle to increase the liquid injection pressure. Fire hoses are usually connected to fire hydrants or fire pumps to transport water to the fire scene to extinguish or control the fire.

[0003] After production, the hose needs to be tested for wear resistance to ensure that it can withstand long-term use and friction, as well as resistance to damage under different environmental conditions. The metal joints of fire hoses are usually corrosion-resistant to ensure long-term reliable operation in harsh environments. When testing existing hoses, workers are required to place them on the test device and then seal and fix them with a water pipe fixture. However, the sealing effect of the water pipe fixture is not good, and multiple sections are required to meet the sealing standards. Therefore, the installation time is greatly increased. At the same time, this fixing structure cannot be reused, which also causes a huge waste of resources and greatly increases the testing cost. Summary of the invention
