A pressure vessel anti-corrosion performance testing equipment

Abstract

The invention discloses a pressure vessel anticorrosion performance testing device, which comprises a detection box, a detection cavity is opened in the detection box, a pressure vessel is rotated in the detection cavity, and the pressure vessel is used as a workpiece to be detected. The pressure vessel includes a main shell, a main shell A detachable sub-shell is fixed on the bottom surface, a dye ring is slid in the detection chamber, first nozzles arranged equidistantly are arranged on the inner peripheral surface of the dye ring, a weighing chamber is provided on the bottom wall of the detection chamber, and the weighing chamber Two left-right symmetrical springs are fixed on the bottom wall, and a weighing plate extending upward is installed sliding in the weighing chamber. There is an injection chamber on the top surface of the disk. The invention can detect the anti-corrosion performance of the inner and outer surfaces of the pressure vessel without causing damage to the pressure vessel, and the invention can plate metal chromium on the metal surface of the pressure vessel after the anti-corrosion test is completed. film, thus playing the role of metal film corrosion protection.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion detection, in particular to a pressure vessel anti-corrosion performance detection equipment. Background technique [0002] A pressure vessel refers to a closed device that contains gas or liquid and carries a certain pressure. Pressure vessels usually have extremely high requirements for airtightness and corrosion resistance, especially for pressure vessels containing corrosive liquids and toxic liquids. [0003] However, in the existing detection operation, after the ultrasonic detector determines the location of cracks and impurities, the workers process to remove the impurities on the outer surface of the pressure vessel, which is not only troublesome to operate, but also low in work efficiency. [0004] Moreover, the traditional anti-corrosion detection device directly takes the pressure vessel out of the detection box after the anti-corrosion detection, resulting in the external envir...

Problems solved by technology

[0003] However, in the existing detection operations, after the ultrasonic detector determines the location of cracks and impurities, the impurities on the outer surface of the pressure vessel are removed through the processing of the staff, which is not only troublesome to operate, but also low in work efficiency.

[0004] Moreover, the traditional anti-corrosion detection device directly takes the pressure vessel out of the detection box after the anti-corrosion detection, resulting in the external environment may cause further corrosion to the unqualified pressure vessel, and the detection of the inner and outer surfaces of the pressure vessel usually requires two Different detection devices are used for detection, the operation is complicated, and the detection efficiency is not high.
