STAND FOR COMPARATIVE ASSESSMENT OF POLYMERIC MATERIALS FOR HYDRO-ABRASIVE WEAR Russian patent published in 2022 - IPC G01N3/56 

FIELD: materials testing.

SUBSTANCE: invention relates to devices for testing materials for hydroabrasive wear. The stand contains a frame on which a belt conveyor with two rotating drums covered with an abrasive belt is installed, and a holder with a test sample. A hole is made in the frame, in which a fastening is installed, on which the tank is fixed with the possibility of removal, in its lower part there is a hole for installing a liquid feeder, which is made in the form of a tube with a flattened flat end. The first drum is a tension drum, fixed with the possibility of displacement along the bed, and the second drum is a drive drum, fixed on the bed. Under the drive drum and the bottom surface of the abrasive belt, a container is installed on the frame to collect the working fluid. The holder is fixed in the guide elements with the possibility of vertical movement, and two platforms are attached to the ends of the holder, the lower platform is intended for fixing the test sample, and the upper platform is intended for installing a test weight. The stand additionally contains a fixed support platform fixed on the frame under the abrasive belt under the platform of its contact with the test sample, and the liquid feeder is located at an angle of 30° to the abrasive belt at a distance of 0.1 m from the line of contact between the abrasive belt and the test sample.

EFFECT: increasing the accuracy and information content of measurements when testing polymeric materials for hydroabrasive wear at a constant temperature in the contact zone of a moving abrasive belt and the test sample.
