High temperature and high pressure vacuum contact thermal resistance testing system

System Introduction:

The RYL-35-20GY high temperature and high pressure vacuum contact thermal resistance testing system is a comprehensive testing system consisting of an induction heating system, a high vacuum extraction system, a high pressure application system, a cooling system, and a control system. The system is mainly used to test the radial temperature transfer of materials by applying high temperature and high pressure in a high vacuum environment; Generate material testing reports through multiple temperature sensors and real-time pressure monitoring; System design temperature: 2000 ℃; The interface pressure reaches 20MPa; Vacuum degree reaches 0.0007Pa

System Design:

According to the testing requirements of the material: high temperature, high pressure, high vacuum, multi-channel temperature sensing, real-time pressure display. We have designed various subsystems, including an induction heating system that achieves a temperature of 2000 ℃; The hydraulic pressure system achieves a maximum interface pressure of 20MPa; Mechanical pump and diffusion pump form a vacuum system; High power cooling water system provides equipment cooling and temperature reduction; The integrated control system can centrally control temperature rise, vacuum extraction, pressure control, and other automatic functions. We have independently developed a PLC control system with a large touch screen control and a Chinese interface for easy operation

Subsystem Introduction:

1、 Induction heating system:

The induction heating system adopts a medium frequency high-power power supply and provides heat source through graphite components, with a maximum temperature of 2000 ℃. The entire vacuum box adopts a stainless steel barrel design, and the large-sized front door design is convenient for testing operation

2、 Pressure system:

The hydraulic system is controlled by the central control PLC to provide an interface pressure of 20MPa. The pressure can be digitized and the pressure application speed can be set through the operation interface; Convenient control of the entire pressure system

3、 Vacuum system:

The entire vacuum box adopts a stainless steel barrel design and a large-sized front opening door design, which facilitates customer sample layout and installation of thermocouples for testing. The vacuum system adopts centralized control to turn on the front-end mechanical pump and diffusion pump, and only needs to be set up in the program to achieve one click operation

4、 Cooling water system

The cooling water adopts a large capacity high-power chiller unit, which can provide sufficient cooling water resources for the entire equipment
