What are the main application scenarios for hydraulic hoses?
Construction machinery: Hydraulic arm connections for excavators, loaders, and cranes.
Industrial equipment: Hydraulic power transmission for injection molding machines, die-casting machines, and machine tools.
Mining and metallurgy: Hydraulic support systems for mine shafts and high-pressure oil pipeline conveyance.
Agricultural machinery: Hydraulic systems for tractors and harvesters.
Marine equipment: Hydraulic control systems for steering gear and deck machinery.
What are the main structural components of a hydraulic hose?
Inner rubber layer: Directly contacts hydraulic oil and must possess oil resistance and corrosion resistance to protect the steel wire layer from erosion.
Middle rubber layer: Enhances the bonding strength between the reinforcement layer and the inner rubber layer.
Steel wire reinforcement layer: Composed of steel wires woven or wrapped together, providing pressure-bearing capacity; the greater the number of steel wire layers, the higher the pressure resistance.
Outer rubber layer: Protects the steel wire layer from mechanical damage, chemical corrosion, and UV aging.
In which scenarios is it appropriate to use hose crimp fittings?
High-pressure hydraulic systems: such as construction machinery, injection molding machines, hydraulic presses, and more.
Chemical medium conveyance: for transporting corrosive fluids in industries like food, pharmaceuticals, and chemical processing.
Frequent disassembly and assembly scenarios: when quick hose replacement is required, a quick-change crimp fitting can be selected.
High-temperature/low-temperature environments: such as high-temperature or low-temperature resistant fittings used in metallurgy and refrigeration equipment.
What is a hose crimp fitting?
A hose crimp fitting is a type of connection component that uses specialized equipment—such as a crimping machine—to integrally join the fitting’s outer sleeve with the hose and fitting core. It is widely used in hydraulic systems, industrial piping, and other similar applications. Its key features include reliable sealing and excellent resistance to delamination, making it suitable for high-pressure environments.
How to choose the right mold and pressure?
Select the corresponding die based on the pipe material (such as carbon steel, stainless steel, or copper pipe) and the outer diameter.
The pressure must be adjusted according to the pipe wall thickness and joint specifications. Refer to the equipment manual or the pressure gauge provided by the manufacturer to avoid excessive pressure that could deform the pipe or insufficient pressure that might cause leaks.
What is the primary function of a hydraulic pipe-locking machine?
The hydraulic pipe crimping machine uses the high pressure provided by a hydraulic system to tightly press metal pipes—such as steel pipes and stainless steel pipes—together with fittings or accessories, thereby creating a sealed connection. It is widely used in fields such as hydraulic systems, automotive manufacturing, and construction machinery.
