1、 Cleaning operation
After using the heat collecting magnetic stirrer, the equipment needs to be cleaned. The specific steps are as follows:
1. Remove the reaction kettle, hot plate and other parts, and clean the residue inside the reaction kettle;
2. Clean the dust and oil stains on the chamber and other accessories of the instrument with a brush or non-woven fabric;
3. Clean the reactor and conditioner with clean water or specialized equipment;
4. Wipe the motor casing, monitor, and human-machine interface clean with a clean towel.
2、 Debugging record
During use, it is necessary to record and debug the usage of the instrument to facilitate preparation and improvement for the next experiment. Mainly includes the following information:
1. Environmental temperature, voltage, current and other parameters before startup;
2. The environmental temperature, internal temperature of the reaction vessel, and internal pressure of the reaction vessel after the experiment is completed;
3. Strict recording of experimental reactions and recording of experimental results.
3、 Regular maintenance
After using the heat collecting magnetic stirrer, it is necessary to maintain the equipment once a year to ensure its long-term stable operation. The specific steps are as follows:
1. Cut off the power supply;
2. Disassemble the casing and remove dust and dirt from the motor;
3. Maintaining motor bearings can include cleaning, lubricating, and checking the condition of the bearings;
4. Check whether the mechanical connection parts of the equipment are loose or worn;
5. Clean the water ring on the hot plate and the inner wall of the stainless steel reactor.
