The Essential Function of Hydraulic Pipes
Hydraulic pipes are like blood vessels in the human body, responsible for transporting hydraulic oil rather than directly pressurizing it. In a hydraulic system, the hydraulic pump-the "heart" of the system-actually generates pressure, compressing the oil to create high pressure through mechanical energy. Pipes, on the other hand, are like highways, simply delivering high-pressure oil to actuators such as hydraulic cylinders or motors.
Key Elements of System Pressurization
Power Source: An electric motor or engine drives the hydraulic pump to rotate.
Pressure Generation: A gear pump/piston pump converts mechanical energy into hydraulic energy.
Pressure Control: A relief valve sets the system's maximum working pressure.
Energy Transfer: Pipes transfer high-pressure oil to the working device.
The Existence of Specially Reinforced Pipes
While ordinary pipes do not pressurize, high-pressure systems employ special designs:
Steel Wire Braided Layer: 4-6 layers of interlaced braiding enhance pressure resistance.
Composite Material: Inner layer of oil-resistant rubber + middle layer of reinforcing fiber + outer layer of wear-resistant coating.
Pulse Testing: Simulating actual working conditions for pressure cycle testing.
Burst Pressure: Typically 3-4 times the working pressure.
