Rubber hose wear tester is an instrument used to evaluate the wear resistance of the outer coating of rubber hoses, hydraulic hoses, and other pipes. It can also be used to test the wear resistance of other pipes and plates. Mainly targeting the outer coating of rubber hoses (such as automotive cables, shoe materials, electronic components, etc.), by simulating the friction conditions between the hose and external objects in actual use, the wear resistance life, surface damage degree, and structural stability of the hose are evaluated, providing data support for the quality control, material improvement, and performance verification of the hose.
The core design of the rubber hose wear resistance testing machine is to simulate actual friction scenarios and achieve quantitative testing of rubber hose wear resistance performance through standardized friction methods and controllable test parameters.
There are three basic principles:
Rotating friction type
Fix the rubber hose sample on the rotating shaft and rotate it at a set speed (such as 0-500r/min). At the same time, let the fixed wear-resistant grinding block (usually made of sandpaper, rubber, metal, etc., selected according to the actual working conditions) press a constant pressure on the surface of the rubber hose. By setting the rotation time or friction frequency, measure the wear of the hose after completion (such as mass loss, volume loss, surface depth change).
Reciprocating friction type
The rubber hose sample is fixed in place, and the wear-resistant grinding block performs reciprocating linear motion (adjustable stroke, such as 0-500mm) through a transmission mechanism to set the pressure and friction with the surface of the rubber hose. Suitable for simulating the wear of rubber hoses in reciprocating motion scenarios (such as rubber hoses swinging with components in construction machinery).
Sand impact type
Standardized sand particles (such as quartz sand, with fixed particle size) are sprayed onto the surface of the rubber hose at a set speed (such as 20-100m/s) through high-pressure airflow, simulating the erosion and wear of the hose in dusty and sandy environments (such as those in mining and construction scenes), and evaluating the wear resistance performance through impact time and sand particle dosage.
maintenance
Daily cleaning: Regularly clean the friction wheel and test bench to prevent the accumulation of debris from affecting accuracy.
Component inspection: Monthly inspection of key components such as loading devices and motors, and replacement of worn parts.
Calibration service: Contact manufacturers annually for pressure, counter, and other calibration to ensure data accuracy.
