Inner rubber layer: In direct contact with transmission media (such as hydraulic oil, coolant, etc.), it needs to have the characteristics of medium corrosion resistance and low friction resistance. Common materials include nitrile rubber, fluororubber, etc.
Enhancement layer: responsible for pressure transmission and structural support, often using methods such as wire weaving and wire winding, which determine the pressure resistance level of the hose (common pressure range is 10-40MPa).
Outer rubber layer: protects the hose from external environmental damage (such as mud, gravel, ultraviolet radiation, high temperature), and requires properties such as wear resistance, weather resistance, and ozone resistance. The material is mostly chloroprene rubber or polyurethane.

High pressure resistance: Suitable for the high pressure requirements of bulldozer hydraulic systems, avoiding rupture caused by excessive pressure.
Flexibility: It can bend flexibly with the movement of mechanical components, compensating for stress caused by equipment vibration or displacement.
Resistant to harsh environments: able to withstand dust, oil stains, high and low temperatures (-40 ℃ to 120 ℃), and mechanical impacts on construction sites.
2, The main types and application scenarios of bulldozer hoses


Function: Transmit hydraulic oil to achieve power transmission of bulldozers (such as blade lifting, bulldozer tilting, track drive, etc.).
Application scenario: Connecting hydraulic pumps, hydraulic cylinders, hydraulic valves and other components, they are the "blood vessels" of hydraulic systems, directly affecting the operational efficiency and action accuracy of bulldozers.

Function: Transport coolant (such as water or antifreeze) to cool down components such as the engine and hydraulic oil radiator.
Application scenario: Connect the water tank, radiator, and engine water jacket to prevent equipment damage due to overheating, especially suitable for continuous operation in high-temperature environments.

Function: Transfer diesel and other fuels from the fuel tank to the engine fuel pump.
Application scenario: It is necessary to have resistance to fuel corrosion and low permeability to avoid safety hazards caused by fuel leakage.

Function: Transmit compressed air for the braking system and pneumatic control components (such as pneumatic horns and valves) of bulldozers.
Application scenario: Ensure that the braking system responds sensitively, ensuring the safety of equipment during driving and operation.
3, Maintenance and replacement of bulldozer hoses
Regular inspection: Check whether the hose has cracks, bulges, aging, loose joints, etc., especially after high-intensity operations, it is necessary to focus on inspection.

Avoid excessive bending: Sufficient bending radius should be reserved during installation to prevent damage to the reinforcement layer caused by excessive bending of the hose.
Timely replacement: When the hose leaks, its pressure resistance decreases, or exceeds its service life (usually 2-3 years), it is necessary to replace it with a qualified product of the same model and specification to avoid faults caused by inferior hoses.
