A Constant Temperature and Humidity System and Its Application on Alternate Immersion Testing Machine

Abstract

The invention provides a constant temperature and humidity system and an alternate immersion testing machine including the system, the constant temperature and humidity system includes a water reservoir, a water pump, a heater, a humidifier, a temperature and humidity sensor, and a circulating water channel; The water channel is located on / in the side wall of the system, and the water in the reservoir is driven by the water pump to enter the circulating water channel for circulation; the heater is one or more, placed in the reservoir and / or the In the circulating water channel; there are one or more humidifiers, which are placed in the space formed inside the constant temperature and humidity system. The constant temperature and humidity system provided by the invention can realize precise control of temperature and humidity in the target operating space, and is especially suitable for the alternating immersion testing machine used for stress corrosion resistance testing.

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...

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.
