Description

technical field [0001] The invention belongs to the technical field of detection devices, and in particular relates to a boiler tube panel automatic hydraulic pressure test device and a working method thereof. Background technique [0002] Boiler equipment tube panels include water-cooled walls and serpentine tubes. According to standard requirements, the above-mentioned components need to undergo hydrostatic tests after they are manufactured to assess their strength and expose possible defects in the manufacturing process. [0003] At present, the water pressure test method of the boiler tube panel is manually operated. One operator is responsible for water supply, one operator is responsible for blocking the tube, and one operator is responsible for the operation of the pressure test pump and checking whether there is leakage in the tube panel. After the test, it is necessary to remove the accumulated water in the tube panel, which is time-consuming and labor-intensive. Mo...

[0003] At present, the water pressure test method of the boiler tube panel is manually operated. One operator is responsible for water supply, one operator is responsible for blocking the tube, and one operator is responsible for the operation of the pressure test pump and checking whether there is leakage in the tube panel. After the test, it is necessary to remove the accumulated water in the tube panel, which is time-consuming and labor-intensive. Moreover, due to the high pressure of the boiler tube panel hydrostatic test, there may be occasions when the plug is not securely sealed and flies out, and there is a great safety hazard in manual operation. , and inefficient
