Equipment for detecting fatigue life of corrugated pipe

Abstract

The invention belongs to the technical field of corrugated pipe detection, particularly relates to equipment for detecting the fatigue life of a corrugated pipe, and aims to solve the problems that conventional equipment for detecting the fatigue life of the corrugated pipe is low in efficiency when the corrugated pipe is fixed, a detection head is inconvenient to replace, and the use requirement cannot be met. The device comprises a base, a detection head and two positioning seats, the rear side of the top of the base is fixedly provided with a supporting plate, the top of the supporting plate is fixedly provided with a fixing plate, the bottom of the fixing plate is fixedly provided with an air cylinder, the output end of the air cylinder is fixedly provided with a connecting plate, and the two sides of the bottom of the connecting plate are both provided with inserting grooves. And plug boards are fixedly mounted on two sides of the top of the detection head. According to the invention, through cooperation of the positioning seat and the fixing seat, rapid and stable fixation of the corrugated pipe is realized, fatigue testing is facilitated, the detection bench is convenient to disassemble and replace, and adaptability is improved.

Description

technical field [0001] The invention relates to the technical field of corrugated pipe detection, in particular to a device for detecting the fatigue life of a corrugated pipe. Background technique [0002] The bellows is a cylindrical thin-wall corrugated shell with multiple transverse corrugations, generally made of stainless steel or copper alloy, and has high axial elasticity. The bellows type mechanical seal has a wide range of applications, from low temperature to high temperature, from neutral medium to corrosive medium, from low speed to high speed, and from ordinary to harsh working conditions. All of these can change the elastic rate of the bellows by changing the geometric shape of the bellows (such as inner and outer diameters, wave plate thickness and wave number, etc.) and the elastic modulus of the material. According to the corrosion performance of the medium, different bellows materials are selected. [0003] The fatigue life limit of the bellows is a key ...
