A subcritical supercritical pressure, temperature and phase state teaching experimental bench

Abstract

The invention discloses a subcritical, supercritical pressure, temperature and phase state teaching experiment bench. The subcritical, supercritical pressure, temperature and phase state teaching experiment bench includes an experiment box body, a steam generation cylinder arranged in the experiment box body, a light source generator located at the rear side of rear transparent quartz glass, a heating system arranged in the experiment box body, a cooling system arranged in the experiment box body, a temperature sensor arranged on the steam generation cylinder, a pressure sensor arranged on the steam generation cylinder, a vapor injection valve communicated with the steam generation cylinder, a liquid discharge valve communicated with the steam generation cylinder, and an upper computer which is connected with the light source generator, the heating system, the cooling system, the temperature sensor and the pressure sensor respectively; and the front side end and the rear side end of the steam generation cylinder are provided with front transparent quartz glass and the rear transparent quartz glass respectively in a sealing manner. The subcritical, supercritical pressure, temperature and phase state teaching experiment bench has the advantages of wide testing range, high bearing pressure, simple operation, safety and reliability, and can improve experiment efficiency.

Description

Technical field

[0001] The invention relates to a teaching experiment table, in particular to a subcritical supercritical pressure, temperature and phase state teaching experiment table. Background technique

[0002] Thermodynamic properties-gas-liquid two-phase saturation state experiment and observation is a very important experimental content in the national quality course "Engineering Thermodynamics". The existing water saturation pressure and temperature relationship experimental platform was developed in the 1990s In the experiment platform, students can only measure the relationship between the gas-liquid saturation pressure of water and the temperature during the experiment, and cannot observe transcritical singular phenomena such as critical opalescence. Besides the water working medium, the experiment table cannot observe other working mediums. For the physical properties of other working fluids in the subcritical and supercritical state in the current scientific resear...
