Technical Field

The invention relates to a constant-pressure gas-carrying cylinder device with a variable volume, belonging to the field of gas containers.

Background

In the existing transformer oil chromatography on-line monitoring device, gas separated from oil is usually carried into a sampling port by carrier gas, and then enters a chromatographic column, and finally the content value of each gas is measured. Therefore, the normal output of the carrier gas is the key for ensuring the successful determination of the gas components in the oil, and the pressure of the carrier gas cylinder is also the key concern during manual inspection. When the pressure of the gas carrying bottle does not meet the requirement, the gas carrying bottle is replaced manually. The gas-carrying cylinder has large volume and heavy weight, which brings great inconvenience to storage, transportation and replacement. Particularly, for economy, a certain number of empty bottles are accumulated and then are uniformly charged to a manufacturer for secondary inflation, and the accumulated empty bottles cause waste of warehouse space. If the air-carrying bottle is replaced by the related personnel, but the air bottles are not classified and stored in the warehouse according to the standard, and the air-carrying bottles are uniform in specification and size, and the later-stage air bottles can be known to be used only by sequentially checking the pressure gauge. In addition, compared with the common scheme of replacing the gas carrying bottle, the gas carrying generating device is adopted in the online oil chromatography monitoring device of some manufacturers to provide carrier gas, although the gas carrying bottle is not required to be replaced, the step of generating the carrier gas is complicated, the complexity of the system is increased, higher technical difficulty is brought to the maintenance of the whole system, and the device cost is too expensive.
