AI Technical Summary
Existing methods for testing the water flow of fire hoses are prone to causing hose bursts and have low testing efficiency, making it impossible to quickly and accurately assess the abrasion resistance of the hoses.
A wear resistance testing device is used to simulate the wear of fire hoses in actual use by combining mounting blocks, grooves, sliders, friction blocks and telescopic motors. Wear is detected by the reciprocating motion of the slider, avoiding water flow testing.
It enables rapid and accurate assessment of the abrasion resistance of fire hoses, improves testing efficiency, reduces raw material consumption, and the test results are more consistent with actual usage conditions.
