Cement constant temperature water curing box with dual temperature settings for upper and lower temperatures

The improved maintenance box has the advantages of more uniform temperature, less temperature difference, and no dripping from the top of the box. The product is designed and manufactured according to the new national standards for the curing requirements of cement, concrete, and cement products. It is suitable for cement plants, construction units, highway and bridge engineering units, and relevant scientific research and quality inspection departments to perform standard curing for the strength and setting time of cement, concrete, and cement product samples.

HBY-64 cement constant temperature water curing box [Precautions]

1. The instrument should be placed steadily and grounded reliably.

2. The water inside the box must not be cut off during work.

3. The instrument operates at a set temperature of ± 1 ℃ without any malfunction.

4. When the power fluctuation exceeds ± 10%, a voltage regulator should be used.

5. Under no circumstances should the instrument tilt more than 45 degrees.

HBY-64 Cement Constant Temperature Water Curing Box [Troubleshooting]

1. The power indicator light is not on, indicating that the power supply has not entered the instrument. After confirming that the external power supply is normal, check if the switch is intact.

2. If the low temperature heating indicator light inside the box does not light up, check whether the contactor has electricity or whether the contactor contacts are burned. If the indicator light is on but the temperature inside the box is very low, it indicates that the heating tube is broken.

3. The high temperature cooling indicator light inside the box is not on. Check if the wiring between the temperature controller and the cooling system is disconnected. If the indicator light is on, check whether the overload protector starter is intact. If it is normal, replace the compressor if it is broken.

4. There is a large temperature difference inside the box. Check if the machine is working. If the cooling indicator light is on but the fan is not working, the fan is damaged. Through the above inspection, except for the refrigeration system malfunction that needs to be sent to the maintenance department for repair, all other malfunctions can be repaired by oneself.

5. If there are special requirements or quality issues, you can directly contact the distributor. Our company produces experimental and testing analysis instruments such as highways, cement building materials, rapid maintenance boxes, drying boxes, high-temperature electric furnaces, prototype machines, boiling boxes, etc., and sells domestic and imported instruments.

HBY-64 Cement Constant Temperature Water Curing Box [Structure and Principle]

1. The box is composed of inner, middle, and outer layers. The inner liner is welded with stainless steel, and the outer shell is formed by bending high-quality cold-rolled steel plates. The middle layer is insulated with polyester foam material. Built in stainless steel rack, divided into 30 and 60 small workshops, each workshop can hold 1 set (3 pieces) of 40 * 40 * 160mm cement mortar test blocks.

2. The temperature control adopts integrated circuits and dual temperature settings, which can accurately control the temperature.

3. The refrigeration system adopts a compressor, a tube coil evaporator, and a U-shaped stainless steel electric heating tube for heating. There are 8 fans inside the box to force cold and hot exchange, reducing the temperature difference and improving uniformity.

4. Working principle

When the temperature inside the box is higher than the set temperature, the temperature controller controls the cooling, and the temperature controller controls the heating system to work, repeatedly cycling to control the temperature within the set temperature range. In order to avoid frequent operation of the thermostat relay, the temperature is set at an upper limit of 21 ℃ and a lower limit of 19 ℃ before leaving the factory, so that the relay's operating range varies within ± 1 ℃.
