AI Technical Summary

Technical Problem

Existing immersion corrosion testing equipment is large in size and complex in structure, resulting in high costs and difficulty in personalized adjustments, and the reliability of indoor simulation test results is low.

Method used

An adjustable immersion corrosion apparatus was designed, which employs a power module, suspension assembly, signal input/output device, and external temperature control. The periodic reciprocating motion of the sample is achieved by driving a lead screw slide rail with an AC motor. Combined with a solution mixing device and temperature control, the equipment structure is simplified and its adjustability is improved.

Benefits of technology

It reduces the cost and assembly difficulty of experimental equipment, reduces space requirements, improves operational freedom and equipment safety, and enables flexible adjustment of experimental conditions.

Abstract

This utility model relates to the technical field of material corrosion testing devices, and more specifically, to a parameter-adjustable immersion corrosion device. It rationally connects various components such as a power module, suspension assembly, signal input / output device, external temperature control, and solution mixing device. The device uses a moving test piece rather than a moving corrosion environment, significantly reducing the size of the corrosion device, lowering equipment complexity, and reducing operating and maintenance costs. Through programmed control of the device's signal input / output, the immersion time and cycle of the material are controlled, and the temperature of the corrosion solution is adjusted. Furthermore, the testing equipment can be used in conjunction with a pure water container, achieving integrated solution "proportioning-mixing-corrosion" through digital display control panel settings. The entire corrosion device offers a high degree of flexibility; the dimensions of each module can be rationally adjusted and combined according to actual needs to better meet the user's testing requirements.
