Abrasion testing machine

automatichosefor production

The instrument permits to perform standard tests and to customize test conditions. It can be successfully used both for production control and for research and development purposes. Standard test cycle The hose under test rotates at a constant speed while the abrasion tool moves back and forth, parallel to the axis of the hose. During each test cycle the hose performs a complete rotation and the abrasion tool performs a complete back and forth movement. The instrument automatically stops, when the set number of cycles has been performed. The evaluation of the result is made by checking if the hose has rigid helix exposed and by measuring the quantity of material removed from the abrasion tool. ISO 29444-1 includes the drawing of Gibitre Device Key Features • Solid structure to prevent vibrations and ensure long duration • Quick replacement of the abrasion tool • Interchangeable weights to set the vertical force on the abrasion tool • Digital speed controller with speed selection • Digital counter of test cycles • Hoses with external diameter up to 100 mm can be tested • Easy setup of the instrument to select test mode and perform tests with or without axial hose rotation • Locked protection door and safety push-button • CE Labelling Additional characteristics The instrument can be set to perform non-standard tests for research puposes: • Different abrading tools with non-standard shape are available and can be easily installed • Non-standard vertical force can be applied by replacing the weight on the abrading tool • The rotation speed for the hose can be set between 0 and 80 rpm • The test can be performed with or without hose rotation
