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

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0024] Such as figure 1 and figure 2 Shown is a water bath test device with alternating temperature difference. The experimental box structure is processed by composite plates made of stainless steel plates and insulation layers. The insulation layer reduces heat loss during the experiment and reduces energy consumption. The experimental box structure is fixed on the angle steel bracket with a sliding device (four-wheel sliding), which is convenient for the handling of the experimental device. Including the total control system 1, the top of the total control system 1 is the control area, where the cycle program is set. The total control system 1 is located in the center of the circular test ...

Abstract

The invention discloses a water bath test device with alternating temperature difference, comprising a general control system (1), the general control system (1) is located in the center of a circular test base structure (6), and the test base structure (6) is provided with a A water-bath heating device (4), a temperature detection and control element (5) for temperature control is arranged in the water-bath heating device (4), and a plurality of water-bath heating devices (4) are arranged in a circle around the center of the general control system (1). Distribution, the general control system (1) is provided with a rotating device, the rotating device drives one end of the component clamping device (2) to rotate along the general control system (1) as the center of the circle, and the other end of the component clamping device (2) is connected with a An electric push rod (8) that drives the sample to move up and down. The water bath test device with alternating temperature difference of the present invention can realize the simulation of temperature changes in areas with large temperature difference in the real environment, and can automatically realize the alternation of temperature difference and temperature amplitude.

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 ...
