  • Patent number: 8833136
    Abstract: The present invention relates to a rotary-drum hydraulic-impact abrasion testing machine, which is used to process an abrasion test and a damage simulation for a plurality of hydraulics structures and comprises: a rotary-drum supporting framework, a rotary-drum and a plurality of sample fixing assembly. The sample fixing assembly at least comprises a housing, a first spacer and a plurality of first studs. In which, there are a plurality of sample openings formed on the side wall of the rotary-drum for respectively accommodating the hydraulics structure samples, and each sample opening is disposed with a long blocking plate and a short blocking plate on the two sides thereof. In the present invention, the rotary-drum hydraulic-impact abrasion testing machine is used to simultaneously execute the abrasion test and the damage simulation for multi hydraulics structures precisely.
