Constant temperature and constant humidity system and application thereof in alternate immersion test machine

Abstract

The invention provides a constant temperature and constant humidity system and an alternate immersion test machine comprising the constant temperature and constant humidity system. The constant temperature and constant humidity system comprises a reservoir, a water pump, heater(s), humidifier(s), a temperature and humidity sensor and a circulating water channel, wherein the circulating water channel is arranged on / in the side wall of the system; the water in the reservoir is driven to enter the circulating water channel for circulating by the water pump; the one or more heater(s) is / are available, and is / are arranged in the reservoir and / or the circulating water channel; the one or more humidifier(s) is / are available, and is / are arranged in a space formed in the constant temperature and constant humidity system. After the constant temperature and constant humidity system is adopted, the temperature and the humidity in a target operating space can be accurately controlled, so that the constant temperature and constant humidity system is especially suitable for the alternate immersion test machine for a stress corrosion resistance test.

Description

technical field [0001] The invention relates to the fields of mechanical equipment and environment control, and in particular to a constant temperature and humidity system and a test device for simulating environmental corrosion. Background technique [0002] The constant temperature and humidity system can change the temperature and humidity in a certain environment in a very small range through temperature control and humidity control devices. It has a wide range of applications in construction, such as incubators for biological strains, aerospace flight capsules, constant temperature and humidity machines for experiments or testing, constant temperature and humidity curing boxes for production or processing, etc., constant temperature and humidity systems have played a significant role. The structure of the constant temperature and humidity system in the existing equipment is relatively simple, and the temperature and humidity fluctuate greatly near the target value. The...

AI Technical Summary

Problems solved by technology

[0004] Most of the current equipment used for stress corrosion resistance testing uses mechanical means to control the test conditions, and the stress corrosion resistance of processed products cannot be expressed intuitively and reliably.

Among them, the existing alternating immersion testing machines are relatively scarce in types, have single functions, and most of them cannot fully meet the conditions and indicators required in the test standards.
