Handling of accidental phenomena

The accidental phenomenon referred to here refers to abnormal phenomena that may occur accidentally during the experimental process without causing safety issues.

During the heating and boosting process, the gauge pressure is higher than the corresponding temperature value. After confirming that the thermometer is not damaged and has been immersed in oil, it can be considered that the instrument is working normally. The reason is that there is a certain proportional relationship between the volume and the amount of water added, and this phenomenon occurs when the amount of water added exceeds the corresponding volume ratio. The solution is to release air appropriately before the pressure approaches the green lower limit pointer, reduce the amount of water, and make the pressure and temperature approach the corresponding values. This operation must be repeated multiple times to achieve, and excessive deflation should be prevented, which would prevent the experiment from continuing.

During the heating and boosting process, the gauge pressure is lower than the corresponding temperature value. After excluding factors such as damage to the pressure gauge, leakage of gas in the kettle body and the joints connected to the gas source, it was found that the amount of water added was less than the corresponding volume ratio. At this time, the test can only be stopped and resumed after adding enough water.
