The working principle of the thermal vacuum test equipment is to simulate the vacuum environment and temperature changes of space through the refrigerant circulation system, water circulation system and electrical automatic control system. The thermal vacuum test equipment is mainly used for testing aerospace and aviation products. It can simulate the vacuum environment and temperature changes in space to test the performance and reliability of the products under extreme conditions. Its working principles mainly include the following aspects: 1. Refrigerant circulation system: The liquid refrigerant absorbs heat from the water in the evaporator and evaporates, creating a temperature difference between the refrigerant and the water, thereby achieving the cooling effect. The gaseous refrigerant after evaporation is compressed by the compressor and transformed back into liquid, then returns to the evaporator to continue absorbing heat, and this process repeats. 2. Water circulation system: The water circulation system pumps water from the water tank to the equipment that needs cooling and takes away the heat from the equipment. As the water temperature rises, it returns to the water tank and is cooled through continuous circulation. 3. Electrical automatic control system: The electrical automatic control system includes the power supply and automatic control parts. The power supply part provides power to the compressor, fan, water pump, etc. through contactors, while the automatic control part includes temperature controllers, pressure protection, relays, delayers, overload protection devices, etc. They automatically start and stop and protect the equipment according to the water temperature.If you need more models about our test equipment, please reference our https://www.chamber-testing.com/ 4. Vacuum system: The vacuum system of the thermal vacuum test equipment detects the pressure in the chamber through pressure transmitters and compares the detected pressure signal with the set value of the control instrument. Then, it controls the opening and closing of the solenoid valve and the operation of the vacuum pump to keep the pressure in the chamber within a certain range. The vacuum system also includes the main pump (mechanical pump) system, molecular pump, connecting pipes, valves, accessories, vacuum sensors, and interlock devices, etc.
