YH-40B type 20 group cement concrete standard curing box

YH-40BType 20 cement concrete standard curing box based onGB1345-99The "Method for Testing the Stability of Cement Standard Consistency, Water Consumption, and Setting Time" is developed, designed, and manufactured based on technical data provided by the Building Materials Research Institute and relevant departments. It is suitable for large, medium, and small cement plants, as well as construction and engineering departments, for the setting and curing of concrete and cement specimens.

YH-40Btype20 sets of cement concrete standard curing boxesOn the basis of the original product, a series of improvements have been made. The box door is sealed with magnetic tape, and the insulation layer is made of insulation cotton with good insulation effect. A refrigeration unit is added inside, which runs smoothly and has low noise. The heater is made of copper tube processing, rust and corrosion prevention, humidification device, beautiful appearance, and high precision of controller temperature control and humidity control. A user troubleshooting and maintenance table has been added in the user manual as a basis for users to provide records to the factory during maintenance, so that our maintenance box can be improved in the production process and the product can be made durable to meet the user's requirements.

YH-40Btype20 sets of cement concrete standard curing boxesStructure and working principle:

1Structure

The box is made of two layers, inner and outer, consisting of an outer box and an inner box. The outer box is made of high-quality cold-rolled steel plate, the inner box is made of stainless steel plate, and the shelves are made of stainless steel profiles, with good corrosion resistance. The water tank below the inner box is used for heating and auxiliary humidification. The humidification system mainly uses ultrasonic humidification instruments, supplemented by water heating and evaporation. The automatic control system is controlled by temperature and humidity control instruments to cool according to the given temperature and humidity, and automatically switch between heating and humidification. The temperature and humidity inside the box are displayed digitally by the instruments.

2Working principle

Temperature control: When the temperature inside the box is lower than the lower limit set value of the temperature controller, the temperature controller outputs a heating signal to command the electric heating element to start working. Conversely, when the temperature is higher than the upper limit set value, the temperature controller commands the refrigeration system to work. When the temperature inside the box reaches the required value, it automatically stops heating or cooling.

Humidity control: Ultrasonic humidifier is used for humidification to ensure that the humidity inside the box reaches ≥95％,The humidification device is automatically controlled by a temperature controller, and when the humidity is less than95%When the temperature controller instructs the humidifier to work, it will automatically stop working when the hysteresis value is reached, and the hysteresis value should be adjusted to0-1℃, not easily too high.

YH-40Btype20 sets of cement concrete standard curing boxesUsage:

1The box is in place, leveled, grounded, and stationary24Add clean water to the water tank when the water level exceeds the heating tube.

2Open the box door and take out the humidifier. Open the side door, place the humidifier on the upper tray, remove the transparent water tank, turn it around, unscrew the water tank cover counterclockwise, fill it with clean water (distilled water), screw on the water tank cover after adding water, put it back into the humidifier body, then press the humidifier nozzle on, and finally insert the humidifier plug into the socket inside the side door. Turn on the power switch and adjust the spray knob to the zui large position. The temperature and humidity of the temperature controller in the maintenance box have been adjusted before leaving the factory.

3Connect the power supply and start the instrument to work. When the temperature and humidity inside the box reach the given value, put the specimen in. Heating and cooling are strictly prohibited from being carried out simultaneously.
