Yh-40b standard constant temperature and humidity curing box

Release time: March 5, 2018 popularity: three hundred and eighty-six

Yh-40b standard constant temperature and humidity curing box is designed and manufactured according to the standard curing requirements of cement and concrete specimens by the state cement Institute and the Ministry of communications. It is an ideal equipment for the laboratory and quality inspection department to maintain the cement and concrete specimens.

Maintenance instructions for yh-40b standard constant temperature and humidity curing box:

     1. Daily maintenance of the constant temperature and humidity test chamber is required every working day, and the maintenance card is filled in. The team leader is responsible for supervising the implementation, and the relevant personnel of the Biotechnology Department have the right to audit at any time
2. Check whether the condenser is clean
3. Check whether the humidifier, humidifier water pan and inner box are clean
5. Check whether the safety device of constant temperature and humidity test chamber is normal
6. The direct operator of the constant temperature and humidity test chamber must have some understanding of the equipment and be able to eliminate basic faults.

Technical parameters of yh-40b standard constant temperature and humidity curing box:

     1. Accuracy of temperature controller: 20 ± 1 ℃
     2. Temperature difference in the box: ≤ 1 ℃
     3. Temperature control: ≥ 90%
     4. Working voltage: 220 V ± 10%
     5. Heating power: 600W
     6. Compressor power: 180W
     7. Internal dimension: 530 × 550 × 1180mm
     8. 20 groups of concrete test blocks can be placed

Notes for yh-40b standard constant temperature and humidity curing box:

1. The instrument must be grounded firmly.  
2. Conduct the bonding test before work to avoid the danger of electric leakage.  
3. The refrigeration system is not allowed to start frequently  it must be started twice every 5 minutes to avoid burning out the compressor.  
Before using the water heater, it is necessary to add water to the instrument box.  
5. The standard curing box should be placed in the indoor environment with ventilation, drying, certificate and no corrosive medium.  
6. The working environment temperature of the instrument is 0-40 ℃.  
7. Before the instrument works, it is necessary to add water to the dry and wet box, remove the box cover, fill the bubble with water suction device, and observe the water level regularly.

Operation procedures of yh-40b standard constant temperature and humidity curing box:

1. After the heating water tank is filled with water, take down the humidifier water tank, screw off the water filling sealing cover under the water tank, add water to 2 / 3, and reset the water tank and humidification pipe. (only the water-proof box is free of water and the heater is burnt out).  
After the instrument is turned on, the humidity is set to 90 ℃, and the temperature is set to be more than or equal to 2%.  
3. After normal operation, load the test piece for maintenance.  
4. When discharging water, open the drain pipe (valve) behind the water tank to drain the water in the curing box, so as to extend the service life of the curing box.
5. In the process of use, the temperature error caused by space error can be automatically eliminated after several programs, so it is not a device problem.
