Abstract

The invention relates to the field of thermodynamic technologies and discloses a full-automatic high-temperature air pressure test system allowing pressure vessel cyclic loading. According to the system, a low-pressure buffer tank connected with an air source is connected with a cyclic compressor, and the cyclic compressor is connected with a high-pressure buffer tank after being connected with another cooling branch in parallel through a loop stop valve; the high-pressure buffer tank is connected with a workpiece through a heater after being connected with a heat exchanger; and the workpieceis connected with a nitrogen water cooler through the heat exchanger, and the nitrogen water cooler is directly connected with the low-pressure buffer tank. Through the system, by the adoption of high-pressure gas heating, gas heat capacity can be remarkably increased, so that heating and cooling efficiency is improved; by use of a cyclic loop system, a gas medium can be utilized repeatedly, wasteis avoided, and system running cost is lowered; full-automatic control of all components, valves and the like of the system is realized through sensor data, the control precision of temperature, flowand other indexes can be improved, human errors are avoided, and the system is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of thermodynamics, and in particular relates to a fully automatic high-temperature air pressure test system for cyclic loading of pressure vessels. Background technique [0002] The first wall, cladding and divertor are the core components of the nuclear fusion reactor, which are subjected to high heat load and nuclear heat of strong neutron deposition during operation, and are vacuum chamber components. In order to remove the heat in time and make the component materials work within the allowable temperature range, complex gas or liquid cooling channels are designed inside the components to uniformly cool the components during operation and avoid unacceptable thermal stress on the component materials. In order to maintain the stable combustion of nuclear fusion plasma, the cooling medium is not allowed to leak slightly. For the International Thermonuclear Experimental Reactor (ITER), it is required that th...
