Corrosion resistance detection equipment for pressure vessel

Abstract

The invention discloses corrosion resistance detection equipment for a pressure vessel. The equipment comprises a detection box, a detection cavity is formed in the detection box, a pressure vessel is rotationally arranged in the detection cavity and serves as a detected workpiece, the pressure vessel comprises a main shell, a detachable auxiliary shell is fixedly installed on the bottom face of the main shell, a dye ring is slidably arranged in the detection cavity, first nozzles arranged at equal intervals are formed in the inner circumferential surface of the dye ring, a weighing cavity is formed in the bottom wall of the detection cavity, two springs in bilateral symmetry are fixedly arranged on the bottom wall of the weighing cavity, a weighing plate extending upwards is arranged in the weighing cavity in a sliding mode, a smooth cavity is formed in the bottom wall of the weighing cavity, an inner measuring disc is arranged in the smooth cavity in a sliding mode, and a jet cavity is formed in the top face of the inner measuring disc. Corrosion resistance detection can be conducted on the inner face and the outer face of the pressure vessel, damage to the pressure vessel is avoided, and the metal face of the pressure vessel can be plated with a metal chromium film after corrosion resistance detection is completed, so the effect of corrosion resistance protection of the metal film is achieved.

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 testing operations, usually 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 efficient. [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 ex...

[0003] However, in the existing testing operations, usually 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 efficient.

[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.
