YH-40B type cement standard curing box curing box wholesale price

Type B cement standard curing box curing box wholesale price
The standard constant temperature and humidity curing box is based on the national B and B "Cement Mortar Strength Test Method" and the technology provided by the National Building Materials Research Institute and relevant departments Designed and manufactured using materials. It is suitable for large, medium and small cement plants, construction and construction departments, and is used for the setting and curing of concrete specimens and cement specimens.
Based on the original curing box, this equipment has made a series of improvements in the overall shape and internal integration. The box door is closed with magnetic strips, and a refrigeration device and humidification device are added inside. It has beautiful appearance and precise temperature control. With a series of advanced advantages, the user's own troubleshooting and maintenance table has been added to the instruction manual as a record provided by the user to the factory during maintenance, so that our factory can further make the product durable during the production process and meet the user's requirements. Ideal purpose of use.

2. Working principle
br/>The working principle of the constant temperature and humidity curing box is that the heating system and the refrigeration system produce heating and cooling, which are controlled by a controller.
When the temperature is lower than (temperature in the box) ℃, the temperature controller relay starts to work. When the temperature in the box is ℃, the electric heater stops heating and keeps the temperature in the box at a constant temperature of ℃. When the temperature in the box is higher than ℃, The refrigeration system starts to work. When the temperature in the box is lower than ℃, the refrigeration system stops working and keeps the temperature inside the box at ℃. It works continuously in this way to achieve the maintenance of the cement specimen.
The constant humidity control adopts ultrasonic humidification and is controlled by a special humidity controller. When the humidity in the box does not reach the required humidity, the humidifier will automatically humidify the box and stop automatically to keep the humidity in the box constant. %.
3. Instructions for use
Place the instrument in a ventilated and dry environment, place it stably and check whether the door switch is flexible.
, move all panel buttons to .
, add water to the water tank to below the last shelf.
, Insert the plug into a well-grounded socket.
, adjust the temperature and humidity controller button to set the required value.
, press the power, cooling, heating, and humidification buttons in sequence, and the instrument will immediately enter the working state.
4. Precautions
The refrigeration system is not allowed to be started frequently. It must be started again every few minutes to avoid burning out the compressor.
The constant temperature curing box for cement specimens is not allowed to be turned upside down to avoid damaging the compressor refrigeration system.
When moving, no tilt angle is allowed.
Conduct an insulation test before work to avoid leakage and danger.
, This instrument must be firmly grounded.
The standard curing box should be placed in a ventilated, dry, flat, non-corrosive medium environment.
, Must be equipped with voltage regulator working voltage.
The cement curing box should be placed in a ventilated and dry place, and used indoors where the ambient temperature is ~℃, the relative humidity is not greater than %, and there is no strong vibration or strong electromagnetic field around it.
After the cement curing box is placed stably, check whether the door switch is flexible and whether the electrical, refrigeration and other components are damaged.
. Fill the water tank in the box to below the last shelf and above the electric heating pipe. Open the side door and fill the humidifier water tank with distilled water. Fill the plastic ball in the temperature measurement dry and wet box with water, and Soak the gauze in water.
Insert the power plug into a well-grounded socket, press the power switch, and the instrument will automatically enter working status.
