Carbon fiber gas cylinder detection system and detection method

Abstract

The invention discloses a carbon fiber cylinder detection system and method. The detection system comprises a hydraulic pressure tester, a hydraulic pressure assisted tester and a tightness tester; the hydraulic pressure tester comprises a test rack, a test operating table, a pressurizing device, a test case mounted on the test rack and a test cart for multiple cylinders to be tested to be placed steadily on; the hydraulic pressure assisted tester comprises a cylinder clamp, a conveying cart and a cylinder emptying and drying apparatus; the tightness tester comprises a tightness test unit and a second gas supply device supplying gas to multiple cylinders to be tested, and the tightness test unit is a cabinet type tightness test unit or a trough type tightness test unit; the method comprises the steps: first, hydraulic pressure testing; second, emptying and drying treatment; third, tightness testing. This system is reasonable in design and simple to operate and effective to use and enables the hydraulic pressure test and tightness test process of multiple carbon fiber cylinders to be finished simply and quickly.

Description

technical field [0001] The invention belongs to the technical field of gas cylinder detection, and in particular relates to a carbon fiber gas cylinder detection system and detection method. Background technique [0002] A gas cylinder is a container under pressure, and the final process of its production process is to conduct a hydrostatic test (also known as a hydrostatic test, see the national standard GB / T9251-1997 for "Hydraulic Test Method of Gas Cylinders" for details) to measure The deformation and pressure bearing capacity under the action of water pressure are used to judge whether the quality of the gas cylinder is qualified. In addition, the gas cylinders need to be inspected regularly during actual use, and the inspection items include the deformation, pressure bearing capacity, and air tightness of the gas cylinders. Among them, when testing the deformation and pressure bearing capacity of the gas cylinder, the hydrostatic test method (also known as the hydros...

AI Technical Summary

Problems solved by technology

But now, there is no special test equipment on the market that can test the deformation and pressure bearing capacity of carbon fiber gas cylinders, and the existing gas cylinder hydraulic test devices are inconvenient to use and operate to varying degrees. Defects and deficiencies such as low efficiency and low test accuracy

In addition, there is no carbon fiber gas cylinder hydraulic auxiliary test device that can pour water and dry carbon fiber gas cylinders after the hydrostatic test is completed. Defects and deficiencies such as low drying efficiency, time-consuming and labor-intensive

Nowadays, the air tightness test of most domestic gas cylinder manufacturers still adopts the traditional water immersion method, which is mainly completed manually. In the actual operation process, there are defects and deficiencies such as inconvenient control of the test process, labor and time-consuming, and poor use effect. , leading to potential safety hazards in the quality of gas cylinders
