Abstract

The invention relates to a liquid impact erosion test device, and particularly relates to a device for performing liquid impact erosion tests in a rotary manner. During testing, liquid ejected by water feeding pipe nozzles impacts test samples mounted on a rotary disc, the liquid is discharged by water discharging pipes, the rotary disc rotates to drive a plurality of the test samples on the edge of the rotary disc to rotate, the test samples impact with the liquid ejected by the water feeding pipe nozzles during rotation of the rotary disc, the test samples are taken down periodically for a plurality of times, cleaned and weighed, and test sample mass changes are recorded and observed. The device can research deformation and erosion of the test samples under liquid impact, and can calculate corrosion resistance, the maximum erosion rate, and other parameters of the liquid impact corrosion through an established data model.

Description

technical field [0001] The patent of the present invention relates to a liquid impact erosion test device, in particular to a test device for liquid impact erosion using a rotating method. Background technique [0002] Liquid impact erosion is the collision between a high-speed nozzle and a solid surface, and it is one of the forms of liquid erosion. Liquid impingement erosion has been found in many components exposed to high-velocity steam containing water droplets, such as low-pressure end blades in large steam turbines, aerodynamic surfaces of aircraft and missiles flying at supersonic speeds in heavy rain. Liquid impact erosion is also the focus of nuclear power system research. Compared with conventional steam systems, nuclear power systems require lower steam quality. When liquid metal is used as the working fluid of the system, liquid metal can aggravate the rapid impact erosion of components. Therefore, the prediction of liquid impingement erosion becomes an importa...
