Third, the product structure
? The outer shell is made of steel plate, and the inner box is made of stainless steel. The thermal insulation layer is foam plastic, which is light and durable, and anti-corrosive.
? Equipped with a closed refrigeration unit, which runs smoothly and has low noise.
? The heater is made of stainless steel tube, which prevents rust and corrosion and prolongs the service life.
? Control the cooling system with digital temperature controller to achieve self-control purpose.
? Humidification system uses ultrasonic humidifier for humidification, and a special temperature controller is used to control the temperature in the box.
四、工作原理
?由加熱系統和制冷系統產生升溫和降溫，用控制儀進行調控。
?當溫度低于(箱內溫度)32℃時，控溫儀繼電器開始工作，箱內溫度32℃時，電熱器停止升溫，保持箱內32℃恒溫，當箱內溫度高于32℃時，制冷系統開始工作，箱內溫度低于32℃時，制冷系統停止工作，保持箱內32℃±1℃，這樣反復連續工作，達到水泥試體養護工作。
?恒濕控制采用超聲波加濕加濕，控濕儀控制，當箱內濕度達不到所需濕度時，加濕器自動向箱內加濕，達到自動停止，以保箱內濕度恒定在90%。
Fourth, the working principle
? The heating and cooling systems generate heating and cooling, which are controlled by a controller.
? When the temperature is lower than (inside the box) 32 ° C, the temperature controller relay starts to work. When the temperature inside the box is 32 ° C, the electric heater stops heating up and keeps the constant temperature in the box at 32 ° C. The refrigeration system starts to work. When the temperature inside the box is lower than 32 ° C, the refrigeration system stops working and keeps the temperature in the box at 32 ° C ± 1 ° C. This way, the continuous work is repeated to achieve the cement specimen maintenance.
? Constant humidity control adopts ultrasonic humidification and humidification, controlled by a humidity controller. When the humidity in the box does not reach the required humidity, the humidifier automatically humidifies the box and stops automatically to ensure that the humidity in the box is constant at 90%.
