constant temperature and humidityChamberWhat are the procedures for safe operation? Today, Baishiqi will talk about the safety operating procedures before the constant temperature and humidity test chamber test. Specifically, as follows:

1. Check the tested parts. The standard vertical constant temperature and humidity test chamber is a non explosion proof equipment and cannot be used to test flammable and explosive materials;

2. Check the placement of the test piece to ensure that the distance between the test piece and the box wall is greater than 10cm, the ratio of the three-dimensional volume to the working chamber volume is greater than 1/3, and the ratio of the cross-sectional area is greater than 1/2;

3. Power on for a short period of time, set the temperature to 35 ° C and the humidity to 5% relative humidity, and test run for about 15 minutes. Check if the water supply to the gauze water tank and humidifier is normal. This step is an important step when a new device is running for the first time or when a test chamber that has not been running for a long time is working again; If the water supply is normal, the equipment can be put into operation at any time.

Safety operating procedures during trial operation:

1. Strictly follow the startup sequence for operation;

2. It is strictly prohibited to open the door during the experiment to avoid affecting the accuracy of the test results and temperature and humidity control. In addition, the evaporator may freeze at low temperatures and cannot continue to operate;

3. Do not frequently modify instrument parameters;

4. Do not open the electrical control cabinet to avoid electric shock;

5. The lighting should be turned off at all times except when necessary;

6. The installation position of wet bulb gauze must be correct to measure accurate relative humidity;

7. The vertical constant temperature and humidity test chamber shall not be closed within 15 minutes before the refrigeration unit is started;

Safety operating procedures after the experiment:

1. Strictly follow the operation manual to shut down the equipment and do not directly operate the emergency stop;

2. After the high and low temperature test, protective measures should be taken before opening the box door to take the test piece to avoid burns or frostbite;

After the low-temperature test or wet heat test, it should be dried and the workshop should be wiped with a dry cloth to ensure cleanliness;

4. Strictly follow the maintenance manual for the vertical constant temperature and humidity test chamber for daily maintenance.
