The invention discloses a
temperature and pressure controllable rotary
erosion experiment apparatus which comprises a frequency control motor, an inner magnetic
assembly, an industrial control computer, a
pressure sensor, a temperature sensor, an electrochemical
workstation, an upper liquid container, an outer magnetic
assembly, a connecting rack, a support cover, a prefilming chamber, an observation window, a transmission center shaft, a lower liquid container, a
circulating pump and a filter. The rotary
erosion experiment apparatus can simulate working conditions of different temperatures, different pressures and the like in the industrial actual environment for
erosion transient characteristic tests. By adopting a magnetic
transmission system, the sealing effect of the experiment apparatus is ensured; the temperature, the pressure and the pH value can be simulated according to the industrial actual environment, therefore, erosion critical characteristics obtained in the tests do not need to be subject to
similarity theory amendment; and an external by-pass circulating
system is additionally arranged, thereby ensuring the balanced distribution of experiment medium temperature fields, and realizing that the working condition environment in the prefilming chamber is identical to the environment in the container. The invention can simulate cases of erosion failure existing in
process type industries of
petrochemical industry,
coal chemical industry,
seawater desalination and the like.
