Humidification process of hot and cold impact test cases

Hot and cold impact test chamber can simulate high temperature environment with low temperature in the middle of the instant change. To distinguish the goods the credibility and reliability of the main parameters is up to standard. Will be sent to you show the forecast analysis and improve the quality of the goods and credibility. Hot and cold impact test cases to test electronic devices, cars, rubber, plastic, navigation hi-tech and high new science and technology, military communications equipment and other goods are changing all the hot cold resistance. So the humidifying process of hot and cold impact test chamber is what? Below to let us together to master: humidity said many, in terms of test equipment, the general narrative are defined with the relative humidity of the humidity. Definition of relative humidity is refers to the water vapor in the air pressure of work and the ratio of the drainage of the saturated steam pressure and temperature expressed as percentage. By water vapor saturation pressure characteristics, the water vapor saturation pressure temperature only on the number of culvert, nothing to do with water vapor can be work of gas pressure, everyone according to a lot of trial and comb for came to the water vapor saturation pressure and temperature in the middle of the association, in which has been the project and many metrological verification chosen should be gove Glenn its formula. It is at this stage the weather bureau personnel allocation humidity check calculate table chooses. Hot and cold impact test chamber and wet process in fact is ascending water vapour pressure of work, at the beginning of the humidifying method since the water is to the environmental test chamber wall, according to the control surface saturation pressure for the water temperature control. Box wall produce very big surface, the surface of the water on the surface to the box based on external diffusion method to box add vapor pressure rise in relative humidity in the environmental test chamber, it appeared in the 1950 s. Because at that time the humidity control is mainly with contacts with mercury electricity conductivity table to carry out simple switch quantity adjustment, in view of the of the big water tank temperature control weak adaptive capacity, and manipulation of cohesive process longer, do not consider variations and dampness of humidification quantity regulation more must more key is in the box wall under the condition of flowing, inevitably there are water spray on the sample on the sample is not the same level of environmental pollution. In addition to hot and cold impact test pipes is also has certain rules in the box. So we choose in early steam humidification and shallow water dish humidification, although it is longer, the manipulation of cohesion process but humidity less ups and downs, after the system software is smooth, more suitable for stable vagina experiment. In addition the water vapor in the process of humidifying but additional calorific value of the heat is not easy to improve the system software. Have, when the temperature of the control flow is less than the experimental point temperature, since the water spray with moisture effect. Definition of relative humidity is refers to the water vapor in the air pressure of work and the ratio of the drainage of the saturated steam pressure and temperature expressed as percentage. The above explanation is the hot and cold impact test box humidification process, hope can help you, if you want to learn more about information about hot and cold impact test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!
