Temperature and pressure controllable rotary erosion experiment apparatus

Abstract

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.

Description

technical field [0001] The invention relates to an erosion experimental device for testing the coupled action of corrosion and flow, in particular to a temperature and pressure controllable rotary erosion experimental device. Background technique [0002] Energy is the foundation of social and economic development, and the petrochemical industry is an important support for the energy industry. With the development of the economy, the petrochemical industry is focusing on the implementation of large-scale, inferior crude oil, and product cleaning strategies. Many pressure equipment and fluid pipelines have occurred in succession. Leakage accidents, such as hydrocracking reaction effluent air cooling Such equipment usually has the characteristics of complex process and harsh working conditions. Once safety accidents such as erosion leakage and fire occur, it will not only seriously affect the production plan, cost and benefit of the enterprise, but also It also seriously thre...
