Description
Technical Field
The utility model belongs to pressure vessel inspection and detection field, concretely relates to a remote supervision and inspection system for pressure vessel withstand voltage test
Background
the manufacture supervision and inspection of pressure-bearing special equipment such as boilers, pressure vessels and the like is one of the main inspection types of the special equipment. The pressure test is a key process carried out in the manufacturing process for verifying the integral strength of the pressure-bearing special equipment, and safety technical specifications such as 'fixed pressure vessel safety technical supervision regulations' (TSG21-2016), 'boiler safety technical supervision regulations' (TSG 0001-2012), 'gas cylinder safety technical supervision regulations' (TSG R0006-2014) and the like make requirements on the pressure test and the air tightness test of the pressure-bearing special equipment.
The TSG21-2016 sets detailed technical requirements on the pressure, temperature, medium and the like of a pressure test of a fixed pressure vessel; the TSG 0001-2012 requires that a hydraulic (pneumatic) test should be performed according to 1.5 times of working pressure for a boiler, boiler components and a boiler after field assembly (installation) is completed, and a related test should meet related technical requirements of a fixed pressure vessel safety technical supervision regulation; particularly, the TSG R0006-2014 also provides relevant requirements for the hydraulic bursting test of the gas cylinder, the hydraulic bursting test should adopt a test device capable of automatically acquiring and recording data for drawing a pressure-water inflow curve, and the hydraulic test device should be capable of automatically recording the number, time and test results in real time.

At present, most of supervision and inspection organizations in China have the conditions that supervision and inspection units are not matched with inspection personnel, the spatial dispersion distance of inspected units is long, the product delivery time is tight, and the like. In most cases, a supervision and inspection organization can only put limited energy on important and relatively dangerous equipment to ensure that the equipment is monitored and inspected on site during a pressure test, and the pressure test inspection of other special pressure-bearing equipment can only adopt a pressure test report after the pressure test is inspected.
The exploration and application of a new mode of 'Internet + detection' promotes the 'robot exchange' in the inspection and detection industry, and is a main way for solving the problems of man-machine contradiction, space dispersion and low efficiency in the manufacturing supervision and inspection of pressure-bearing special equipment. The method has the advantages that the research of mobile interconnection application technology is enhanced, the cross-platform and cross-region mobile inspection detection service is realized, the virtual-real combined inspection detection process is established through the research, the complementary composition of online and offline detection technology is realized, the convenience level of the inspection detection service is improved, the application of intelligent detection in the manufacturing supervision and inspection of the pressure-bearing special equipment is promoted, and the method has important significance.
