Integrated control system for airtight inspection of aircraft and using method of integrated control system

Abstract

The invention relates to the technical field of detection equipment, in particular to an integrated control system for airtight inspection of an aircraft and a using method of the integrated control system. The integrated control system is mainly applied to airtight performance detections of relating pasts of the aircraft. The integrated control system comprises an intake and exhaust system and apipeline butting system, wherein the intake and exhaust system comprises a gas source pipeline, a gas supply pipeline and a detection pipeline, which facilitates the connection between a gas source and a pressure chamber to be detected, and the gas source pipeline comprises a gas source pipe and a gas source valve; the gas supply pipeline comprises a gas supply pipe and a gas supply valve, and thedetection pipeline comprises a detection pipe, a detection exhaust valve and a detection pressure gauge; the gas source pipe is communicated with the gas supply pipe, and the pipeline butting systemcomprises a gas connecting port, a detection connecting port and a gas source connecting port; the gas supply connecting port is arranged on the gas supply pipe, and the detection connecting port is arranged on the detection pipe; the gas source connecting port is arranged on the gas source pipe, and the gas supply connecting port and the detection connecting port are communicated with the pressure chamber to be detected. The pipeline can be quickly communicated or cut off by the three-valve design, so that the ventilation pressure of each pipeline can be conveniently determined, and the accuracy of testings is ensured.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to an aircraft airtight inspection comprehensive control system and a method for using the same. It is mainly suitable for airtight performance testing of relevant parts of the aircraft. Background technique [0002] 1. The existing air tightness testing equipment is bulky and heavy, with a weight of 20-40 kg, a length and width of 48-65 cm, and a height of 30-50 cm. In view of the weight and size of the above-mentioned equipment, two people are required to carry it And it is equipped with a special delivery rack, which brings great inconvenience to the testers. [0003] 2. Due to the problem of the range of the mechanical meter, the existing measuring equipment needs to be equipped with multiple measuring pipelines. When measuring the cavity parts of the aircraft with different air tightness requirements, the measuring pipelines need to be replaced, which increases the...

Problems solved by technology

[0002] 1. The existing air tightness testing equipment is bulky and heavy, with a weight of 20-40 kg, a length and width of 48-65 cm, and a height of 30-50 cm. In view of the weight and size of the above-mentioned equipment, two people are required to carry it And it is equipped with a special transport rack, which brings great inconvenience to the testers

[0003] 2. Due to the problem of the range of the mechanical meter, the existing measuring equipment needs to be equipped with multiple measuring pipelines. When measuring the cavity parts of the aircraft with different air tightness requirements, the measuring pipelines need to be replaced, which increases the workload of the testers. At the same time Due to the multi-pipeline design of the existing equipment, the number of instruments, pipelines, parts and connectors used is large, and the use of mechanical meters is likely to cause insufficient measurement accuracy, easy to produce reading deviations, and cause inaccurate measurements.

[0004] 3. Due to the multi-pipeline design, the surveyor needs to accurately select the applicable pipeline. Selecting an inappropriate pipeline for measurement will cause measurement data deviation, and in severe cases, it will also cause damage to the corresponding pipeline parts and connectors. The operation is complicated and easy. cause misuse
