The fully enclosed high and low temperature liquid circulation device is specially used for heating and cooling of various reactors and reactors, and chemical reactions are carried out under different pressures and flow rates under different conditions
.
In the pharmaceutical and chemical industry, in addition to the use of fully enclosed high and low temperature liquid circulation devices, there are often various chemical reactions, so it is necessary to pay attention to the heat generated in the reaction process in time to avoid failure due to excessive heat
.
1.
It should be kept clean and dry, and it is strictly forbidden to heat the stainless steel reactor without solution, so as to avoid burning out the reactor
.
2.
If the measured temperature is very different from the actual temperature, it is usually caused by sensor error.
Put the sensor in boiling water and the meter should display 100.
Check whether the sensor is consistent with the input type of the instrument
.
3.
The display of the equipment and meter is normal, but the temperature is suddenly out of control.
Check whether the external load is short-circuited or open-circuited, the measured value is lower than the lower limit of the instrument range or the thermocouple is reversed
.
4.
When not working, the power supply should be cut off
.
To ensure safety, please connect the ground wire when using
.
5.
The power of the equipment itself and the heat taken by the refrigerant from the load need to be discharged from the radiator at the front ventilation hood
.
If the front ventilation hood is full of dust, it will hinder the heat dissipation and the cooling effect will be greatly reduced
.
Generally speaking, under normal use conditions, the decrease in cooling capacity is caused by poor ventilation and heat dissipation or high ambient temperature
.
For many chemical reactions, not only the upper temperature limit is important for safety, but the lower limit temperature is also important, to understand the consequences of deviations in key safety parameters such as temperature, pressure, etc.
Consequences of high and low, knowing what to do when a deviation occurs
