Abstract

The invention relates to a multifunctional comprehensive abrasion test rotary table which comprises a table body I, an elastic tube, a table body II, a table seat, a seal filler, wires, wiring terminals, a test sample and an insulating sleeve, wherein the test sample is installed on the table body I and table body II in an oriented and insulation mode. When being installed on a rotary abrasion machine and rotating at high speed, the rotary table can complete the single or multiple combination abrasion tests of cavitation erosion, washout erosion and electrochemical etching. An air-permeable cavitation erosion source arranged on the table body can test the cavitation erosion source pressure or generate artificial cavitation. A test sample orienting device can implement frequent test sample mounting and demounting without changing the mounting position, thereby achieving the goal of monitoring the abrasion pattern. The invention provides a convenient and quick test rotary table for researching the abrasion mechanism and evaluating and developing the washout-erosion-resistant cavitation-erosion-resistant corrosion-resistant material. The device for monitoring the cavitation erosion source pressure or generating artificial cavitation on the rotary table provides the basic test device for washout erosion, cavitation erosion, electrochemical etching and combination thereof under super cavitation conditions.
