Third, the cement constant temperature and humidity standard maintenance box structure
★ The outer case of the maintenance box is A steel plate, and the inner box body is made of stainless steel plate. The thermal insulation layer is foam plastic, which is light and durable. .
★ Equipped with a closed refrigeration unit, which runs smoothly and has low noise.
★ The heater is made of stainless steel tube to prevent rust and corrosion and prolong the service life.

四、水泥恒温恒湿标准养护箱工作原理，由加热系统和制冷系统产生升温和降温，用控制仪进行调控。
★当温度低于(箱内温度)20℃时，控温仪继电器开始工作，箱内温度20℃时，电热器停止升温，保持箱内20℃恒温，当箱内温度高于20℃时，制冷系统开始工作，箱内温度低于20℃时，制冷系统停止工作，保持箱内20℃±1℃，这样反复连续工作，达到水泥试体养护工作。
★恒湿控制采用超声波加湿加湿，专用控湿仪控制，当箱内湿度达不到所需湿度时，加湿器自动向箱内加湿，达到自动停止，以保箱内湿度恒定在90%。
Fourth, the cement constant temperature and humidity standard maintenance box works, heating and cooling systems generate heating and cooling, and control with a controller.
★ When the temperature is lower than (inside the box) 20 ℃, the temperature controller relay starts to work. When the temperature inside the box is 20 ℃, the electric heater stops heating up and keeps the constant temperature inside the box. When the temperature inside the box is higher than 20 ℃, The refrigeration system starts to work. When the temperature inside the box is lower than 20 ° C, the refrigeration system stops working and keeps the temperature in the box at 20 ° C ± 1 ° C. This way, the continuous work is repeated to achieve the cement specimen maintenance work.
★ Constant humidity control adopts ultrasonic humidification and humidification, and is controlled by a special humidity controller. When the humidity in the box does not reach the required humidity, the humidifier automatically humidifies the box and stops automatically to keep the humidity in the box constant at 90%.
五、水泥恒温恒湿标准养护箱操作使用：
★取出加湿器，拿下上部水箱向加湿器加足水(纯净水)再放回底座。
★打开箱体侧门，把加湿器安装在托板上装上加湿机接头并和箱内进气管接好，插上电源插头。
★接通电源，打开电源开关，进行温度设置，按动控制器上温度，设定拨码，使之为控制温度(即20℃)。湿度设定，把湿度设定为控制湿度90%，然后再打开所有控制开关，即可自动控制。
★箱体 位静止24小时后，接好地线调节好水平，向水箱内加清洁水，水位超过加热管。
水泥恒温恒湿标准养护箱注意事项：
★制冷系统不准频繁启动，必须间隔5分钟再开始二次启动，以免烧坏压缩机。
★水泥试体恒温养护箱不准倒置，以免损坏压缩机制冷系统。
★搬动时，不得倾斜45°角。
★工作前进行绝缘测试，以免漏电，发生危险。
★本仪器必须接地牢固。
★标准养护箱应置于通风、干燥、平整、无腐蚀性介质环境中使用。
★必须配调压器工作电压220V建议：当箱内温度达到设定温度，而室内温度也高于设定温度时，可只选制冷工作，将加热功能键置于oFF。当箱内温度低于设定温度时而室内温度也低于设定温度时，可只选择加热工作将制冷键置于OFF。当环境温度在设定温度上下波动时，应选择制冷与加热同时工作。合理使用设备，将使设备的使用寿命大大提高。
★温度通常设定在20℃，所以说明书上只标20℃，但也有用户需要使用25℃温度的，所以该养护箱的温度是可以调节的，调节范围一般控制在20℃～50℃（实际的控温范围可能还会大一些，但要考虑夏天温度较高，底于20℃功率上有时达不到；高于50℃后门的封条会变软，影响密封。）每次调节的幅度可在0.1℃。湿度也是可调的，范围为95%～99%，幅度为1%。其它的水泥标准养护箱和混凝土标准养护箱也基本相同。
V. Operation and use of cement constant temperature and humidity standard curing box:
★ Take out the humidifier, remove the upper water tank, add enough water (purified water) to the humidifier, and then put it back into the base.
★ Open the side door of the box, install the humidifier on the pallet, install the humidifier connector, and connect it with the intake pipe in the box, and plug in the power plug.
★ Turn on the power, turn on the power switch, set the temperature, press the temperature on the controller, and set the dial code to make it the control temperature (that is, 20 ° C). Humidity setting, set the humidity to 90% of the control humidity, and then turn on all control switches for automatic control.
★ After the box is left at rest for 24 hours, connect the ground wire to adjust the level, add clean water to the water tank, and the water level exceeds the heating pipe.
Note for cement constant temperature and humidity standard curing box:
★ Refrigeration system is not allowed to start frequently. It must be restarted for 5 minutes to avoid starting the compressor.
★ The cement sample constant temperature curing box is not allowed to be inverted, so as not to damage the compressor refrigeration system.
★ When moving, do not tilt at an angle of 45 °.
★ Perform insulation test before work to avoid leakage and danger.
★ This instrument must be grounded firmly.
★ The standard curing box should be placed in a ventilated, dry, flat, non-corrosive medium environment.
★ It must be equipped with a voltage regulator with a working voltage of 220V. Suggestion: When the temperature in the box reaches the set temperature, and the indoor temperature is higher than the set temperature, you can only select the cooling work and set the heating function key to oFF. When the temperature inside the box is lower than the set temperature and the indoor temperature is lower than the set temperature, only the heating operation can be selected to turn the cooling key to OFF. When the ambient temperature fluctuates above and below the set temperature, cooling and heating should be selected to work simultaneously. Proper use of equipment will greatly increase the service life of the equipment.
★ The temperature is usually set at 20 ℃, so the manual only indicates 20 ℃, but some users need to use the temperature of 25 ℃, so the temperature of the maintenance box can be adjusted, and the adjustment range is generally controlled between 20 ℃ ～ 50 ℃ (actual The temperature control range may be larger, but it is necessary to consider that the summer temperature is high, and the power at 20 ° C is sometimes not reached; the seal of the back door above 50 ° C will soften, affecting the seal.) The amplitude of each adjustment can be At 0.1 ° C. Humidity is also adjustable, ranging from 95% to 99%, with a range of 1%. Other cement standard curing boxes and concrete standard curing boxes are basically the same.
