hose structure

  • Strong Adsorption Capacity

    The activated carbon filter element is made of high-quality activated carbon, which has ahuge specific surface area and rich micropore structure, making it have a high adsorption capacity andcan efficiently adsorb and remove various pollutants in water, including residual chlorine, odor,organic matter, heavy metal ions and so on. At the same time, activated carbon air conditioning filtercan also effectively remove odor, toxic and harmful gases, bacteria and other pollutants in the air.

Impulse Test

 

An impulse test is a critical procedure used to evaluate the durability and reliability of hydraulic hoses under cyclic pressure conditions. This test simulates the repeated pressure fluctuations that hydraulic hoses experience in real-world applications, ensuring they can withstand the stress without failing.

 

 

01

Purpose of the Impulse Test

  • Assess Durability

    Determine how well the hose can endure repeated pressure cycles.

  • Ensure Safety

    Verify that the hose will not fail under operational conditions, preventing potential hazards.

  • Quality Control

    Confirm that the hose meets industry standards and specifications.

 

 

 

02

Test Procedure

  • Setup

    The hose is installed in a test rig that can generate controlled pressure impulses.

  • Pressure Application

    The hose is subjected to a series of pressure cycles, typically ranging from a minimum pressure (often zero or a low value) to a maximum pressure (specified by the hose's rating or application requirements).

  • Cycle Counting

    The number of cycles the hose can endure before failure is recorded. This number is compared against industry standards or specific requirements.

  • Failure Criteria

    Failure is typically defined by visible damage, leakage, or a significant drop in pressure.

 

 

 

03

Key Parameters

  • Pressure Range

    The minimum and maximum pressures applied during each cycle.

  • Frequency

    The rate at which pressure cycles are applied.

  • Temperature

    The ambient or operational temperature during the test.

  • Fluid Type

    The type of hydraulic fluid used in the test, which should match the intended application.

 

 

04

Standards and Specifications

  • SAE J343

    Society of Automotive Engineers standard for hydraulic hose testing.

  • ISO 6803

    International Organization for Standardization standard for rubber and plastics hoses.

  • DIN EN 853

    German standard for wire braid reinforced hydraulic hoses.

 

 

05

Importance

  • Reliability

    Ensures the hose can perform reliably under cyclic pressure conditions.

  • Longevity

    Helps predict the service life of the hose.

  • Compliance

    Ensures the hose meets regulatory and industry standards.

06

Conclusion

  • The impulse test is an essential part of the quality assurance process for hydraulic hoses. It helps manufacturers and users alike to ensure that the hoses can withstand the rigors of their intended applications, thereby enhancing safety and performance.
