Washing air supply system capable of automatically supplementing water and operation method

Abstract

The invention discloses a washing air supply system capable of automatically replenishing the water and an operation method. The washing air supply system mainly comprises a spray nozzle, a main saturator, an auxiliary saturator, a water replenishing tank and a control system, wherein the spray nozzle is communicated with the top of the main saturator, the test box and the brine tank, compressed gas is introduced into the main saturator, the main saturator is communicated with the auxiliary saturator through a pipeline, a first electromagnetic valve is arranged on a pipeline for communicatingthe tops of the main saturator and the auxiliary saturator, a second electromagnetic valve is arranged on a pipeline for communicating the bottoms of the main saturator and the auxiliary saturator, the water replenishing tank is positioned above the secondary saturator, the auxiliary saturator is provided with a third delay control valve, a fourth pressure release valve, a high-water-level liquidlevel switch and a low-water-level liquid level switch, the control system can receive difference signals of the liquid level where the high-water-level liquid level switch and the low-water-level liquid level switch are located and control opening and closing of the first electromagnetic valve, the second electromagnetic valve, the third delay control valve and the fourth pressure release valve.The washing air supply system is ingenious in structure, capable of guaranteeing continuity and accuracy of the test process, low in cost and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of salt spray corrosion test, in particular to a water washing air supply system and an operation method for automatic water replenishment. Background technique [0002] The salt spray corrosion test chamber mainly uses the configured salt water to atomize it, and then attaches the atomized salt spray to the surface of the sample to conduct corrosion tests on the sample. Compressed air is needed in the salt water atomization process. In order to ensure the cleanliness of the compressed air, the compressed air needs to be washed first to remove the oil in the compressed air; the water washing of the compressed air needs to rely on the air saturator; there is pure water in the air saturator And the heater, the heater heats the compressed air passing through, and the compressed air is washed by pure water, and the compressed air after heating and washing brings a little moisture from the saturator to the nozzle...

AI Technical Summary

Problems solved by technology

[0005] (1) It is necessary to increase the use of anti-corrosion pumps and increase the wall thickness and pressure resistance of the saturator, thereby greatly increasing the cost of the entire test chamber;

[0006] (2) During the pumping process, the pump may bring in air to affect the test results of the test chamber;

[0007] (3) It will directly affect the spray pressure, cause spray fluctuations, and affect the accuracy of the test;

[0008] Generally speaking, neither of the above two water supplements can well meet the requirements of the salt spray corrosion test chamber.
