A separate fully automatic spray dry-wet cycle test device

Abstract

The invention relates to a separate fully automatic spray dry-wet cycle test device, which comprises a spray box and a water vapor control box, which are separated from each other and connected as a whole through water pipes and air pipes. This test device can individually place the spray box in a specific test environment according to the test requirements. According to the test working conditions, set the number of dry and wet cycles on the infinite cycle controller. In the wet state, the No. 1 pump of the water tank starts to work to realize the spray test of the specimen and realize the recycling of the spray liquid at the same time; in the dry state , the No. 1 pump stops working, the No. 2 pump continues to work, and the hot air blower starts to work, which can realize self-control of hot and cold air, dry the specimen, and stop running when the set number of cycles is reached. The invention has the advantages of simple and practical structure, convenient and flexible operation, high work efficiency, stable operation process and good test effect.

Description

Technical field [0001] The invention is a separate automatic spraying dry-wet cycle test device, belonging to the field of civil engineering. Background technique [0002] Studies have shown that the corrosion of chloride salts will cause the steel bars in the concrete to deblunt, cause the steel bars to rust, and accelerate the destruction of the reinforced concrete structure. Many scholars have conducted research on the transmission of chloride ions in concrete, but there are still many remaining problems. With the further in-depth study of the basic disciplines of civil engineering, the test needs to be closely integrated with the actual structure environment, and the working conditions considered are becoming more and more complex. In the Three-North region of my country, the coastal and offshore concrete structures in the cold regions are subject to the combined effects of freezing and thawing and chloride salt erosion, and the rock masses may be subject to the combined eff...

Problems solved by technology

Combined with the existing walk-in high and low temperature variable humidity test chamber, the above special working conditions can be realized, but the current spraying and dry-wet circulation systems are all integrated test devices, which are large in size and limited in use conditions, and cannot be used in severe cold and Use in high temperature environment

During the test, watering is generally done manually, that is, entering the test chamber at a temperature above zero to spray salt water. In this case, the workload is large, the demand for salt water is large, and it is easy to corrode other equipment, and it is impossible to guarantee 24-hour manning, and the accuracy is low.
