The sampler set with the high-level radioactive waste liquid sampling rod based on servo control and accurate sampling performs sampling of each layer of organic phase, clear liquid phase and mud phase for quantitative and accurate sampling; pull rope sensor steel wire rope and boom positioning pull rope displacement sensor , to achieve real-time position monitoring and control of accurate sampling; the overall structure is stable, the sampling point is positioned accurately, and the sampling volume is accurate.

Description

technical field [0001] The invention relates to the technical field of storage detection and sampling of nuclear waste liquid in the field of nuclear industry, in particular to a high-level waste liquid sampling rod based on servo control for accurate sampling. Background technique [0002] With the reserve and long-term development of nuclear industry automation technology, it is necessary to regularly sample and analyze the high-level liquid in the storage pool during the storage of high-level waste liquid in the nuclear industry. The problem of inaccuracy, due to the high radiation pollution of the sampled samples, the sample volume used for analysis needs to be strictly controlled, too much sample volume will increase the radiation dose, so a high-level radioactive waste based on servo control for accurate sampling is required The liquid sampling rod makes the positioning of the sampling point accurate and the sampling volume accurate.
