A leak detection system and control method for a water-cooled radiator

Abstract

The invention discloses a leakage detection system and an operation method for a water cooling radiator, and the system comprises a circulating pipe connected with a water cooling radiator, pressure detection sensors and an isolating valve. The isolating valve is used for opening or closing the circulating pipe. The pressure detection sensors are disposed between the isolating valve and the circulating pipe, and detect the internal pressure change of the circulating pipe. The system also comprises a gas processing device. The gas processing device is disposed at the other end of the isolating valve. The gas processing device comprises a gas buffering storage tank, a temperature detection unit, a gas compensation unit, and a control unit. One end of the gas buffering storage tank is connected with compressed air through a pressure regulating valve, and the other end of the gas buffering storage tank is communicated with the isolating valve. The temperature detection unit is disposed in the gas buffering storage tank, and is electrically connected with the control unit. The system and method are low in detection cost, and are high in detection efficiency and precision. The system and method carry out the preprocessing of detection gas, and greatly reduce the external factors affecting the detection precision.

Description

technical field [0001] The invention relates to a detection system, in particular to a leakage detection system and operation method for a water-cooled radiator. Background technique [0002] At present, the equipment used for water-cooled radiator leakage testing mainly uses air directly into the circulation pipeline connected to the water-cooled radiator for detection. This method is detected due to factors such as the external environment, temperature, and the impact of compressed gas The detection accuracy is very low, which cannot meet the needs of leak detection; therefore, in order to improve the accuracy of leak detection, people use helium for detection, and use molecular level detection. The high precision meets people's needs for detection accuracy, but there are still the following defects: ( 1) The helium detection method is affected by too many factors, resulting in unstable detection results; (2) The detection speed is slow, the detection time is long, and it ...
