Comprehensive performance detection system of breathing apparatus

Abstract

The invention provides a comprehensive performance detection system of a breathing apparatus. The comprehensive performance detection system comprises a detection platform, an actuating mechanism control system and a detected data processing device; the detection platform mainly comprises a compression chamber, an air control system which is communicated with the compression chamber, an artificial lung for simulating body breathing, valves for connecting the breathing apparatus and sensors of the valves; the actuating mechanism control system comprises an industrial personal computer, wherein the industrial personal computer is used for controlling the controlled valves to open and close, starting a breathing apparatus motor of the artificial lung to work and controlling the pressure variation of the compression chamber, and an actuating mechanism is used for controlling through buttons on a software interface; and the detected data processing device comprises a computer processing system and a printing device. The detection system can simulate the working condition of an underwater breathing apparatus in the deepwater pressure environment, the pressures and flow parameters of all the valves are detected through the sensors and are digitally displayed, so that factors of man-made misreading, misinformation and the like are reduced, and results are more intuitively and accurately. The system detects the working conditions of all the valves of the breathing apparatus at 120 meters or less under the water, and is particularly suitable for tests for detecting the performance parameters of underwater rescue breathing apparatuses.

Description

Technical field [0001] The invention belongs to instrument testing equipment, and specifically relates to a comprehensive performance testing system for diving respirators. [0002] Background technique [0003] A diving respirator is a device to ensure that divers maintain normal breathing in the water. With the development of science and technology, the requirements for the performance of submersible respirators are higher. The quality inspection and performance testing of deep-sea submersible respirators used for scientific investigations or submarines are particularly important. For example, due to historical reasons, submarine crew escape equipment only tests individual components such as main valves, breathing bags, and gas cylinders, and cannot perform comprehensive performance tests on the entire respirator. There is neither testing means nor specialized equipment. The comprehensive performance of diving respirators, especially deep-water diving respirators, has not been ...
