The invention relates to a sand-prevention sifting pipe erosion-resistance experiment device. The device comprises at least one experiment unit. Each experiment unit comprises an experiment pipe and anozzle; a to-be-tested sand-prevention sifting net is arranged in each experiment pipe. and each experiment pipe is partitioned into an injection section and an output section in the axial direction;the nozzles are connected with the injection sections, and sand-containing fluid is jetted out to the to-be-tested sand-prevention sifting nets; the injection sections and the output sections are provided with first outlets and second outlets for the sand-containing fluid to flow out respectively. By means of the experiment pipes provided with the to-be-tested sand-prevention sifting nets, a sand-prevention sifting pipe can be simulated, the experiment units can simulate the submerged erosion to the to-be-tested sand-prevention sifting nets by the sand-containing fluid at a certain speed, whether or not the reliability of the to-be-tested sand-prevention sifting nets meets the requirement is judged, the testing method is convenient and quick, and the convenience of experiments is facilitated.
