Water bath testing device with temperature difference alternating

Abstract

The invention discloses a water bath testing device with temperature difference alternating. The water bath testing device comprises a main control system (1); the main control system (1) is located at the center of a ring testing base structure (6); the ring testing base structure (6) is provided with a plurality of water bath heating devices (4); the water bath heating devices (4) are internallyprovided with temperature detecting and controlling elements (5) used for controlling the temperature; the water bath heating devices (4) are arranged circumferentially with the main control system (1) as the center; the main control system (1) is provided with a rotating device; the rotating device drives one end of a component clamping device (2) to rotate with the main control system (1) as the center; and the other end of the component clamping device (2) is connected with an electric push rod (8) driving a sample to move up and down. According to the water bath testing device with alternating temperature difference, simulation of temperature change in area with large temperature difference in actual environment is achieved, and alternating between the temperature difference and temperature amplitude is achieved automatically.

Description

technical field [0001] The invention relates to a water bath test device with alternating temperature difference, which belongs to the field of test and research of corrosion and protection and material durability. Background technique [0002] Corrosion of materials not only causes huge economic losses, but also creates potential safety hazards and affects the normal operation of structures if not properly protected. Components located in areas with large temperature differences such as coastal areas are most severely corroded due to the coupling effect of various harsh environmental factors such as alternating dry and wet conditions, large temperature differences between day and night, and sunlight exposure. The anti-corrosion design of the area has important scientific significance. At present, experiments to study the influence of temperature changes on corrosion are mainly field experiments or indoor manual operations. However, field experiments are limited by factors ...

AI Technical Summary

Problems solved by technology

At present, experiments to study the influence of temperature changes on corrosion are mainly field experiments or indoor manual operations. However, field experiments are limited by factors such as geographical location and field conditions, and data collection is difficult, which is not conducive to grasping the influence of various factors on the corrosion characteristics of materials. However, indoor manual operation cannot solve the problems of long experimental cycle and frequent operation, which is not conducive to long-term observation experiments
