The gas cylinder is a pressure-bearing container, and the final process of the production process is to perform a hydraulic test (also called a hydraulic test, see national standard GB/T9251-1997 of gas cylinder hydraulic test method for details) to measure the deformation and the pressure-bearing capacity under the action of the hydraulic pressure and judge whether the quality of the gas cylinder is qualified or not. In addition, the gas cylinder is required to be detected regularly in the actual use process, and detection items comprise deformation, pressure bearing capacity, air tightness and the like of the gas cylinder. When the deformation and the pressure bearing capacity of the gas cylinder are tested, a water pressure testing method (also called a water pressure testing method) is adopted. At present, the adopted hydrostatic test method mainly comprises a burette method and a weighing method, wherein the weighing method is widely applied.

The carbon fiber gas cylinder belongs to a composite gas cylinder, adopts a metal liner, is formed by winding carbon fibers outside and performing high-temperature curing processing, and has the pressure resistance of 30 MPa. Compared with a metal gas cylinder (a seamless steel cylinder and the like), the carbon fiber gas cylinder has better performance, the weight is reduced by more than 50%, the operation and the use are easier, and the carbon fiber gas cylinder is more convenient to use when a dangerous area in deep underground (such as a mine and the like, petroleum and petrochemical industry and the like) meets rescue conditions or severe disaster conditions. In addition, the composite gas cylinder is also a poor conductor of electricity, and the composite gas cylinder is neutralized in corrosion and erosion occasions, so that the composite gas cylinder is safer to use. According to legal rules and practical use standard requirements, the gas cylinder must be subjected to a regular hydrostatic test, and after the hydrostatic test is completed, the gas cylinder must be dried, so that the gas cylinder is clean and dry and is convenient to use. However, at present, a set of special test equipment capable of testing the deformation and the pressure bearing capacity of the carbon fiber gas cylinder does not exist in the market, and the existing gas cylinder hydrostatic test devices have the defects and the defects of inconvenience in use and operation, low test efficiency, low test precision and the like to different degrees.
