Daily Maintenance of Reaction Kettle

Reaction kettle is an important equipment widely used in chemical, pharmaceutical, food and other industries, mainly used for material mixing, reaction, heating, cooling and other processes. Due to its long-term work in high temperature, high pressure, corrosive environment, the daily maintenance of the reactor is particularly important. Good maintenance can not only extend the service life of the equipment, but also ensure the safety and efficiency of production. The following is a detailed guide on the daily maintenance of reaction kettle.

Cleaning and Inspection

1.Regular cleaning
Internal cleaning: After the reaction, the kettle should be cleaned of residues in time to avoid drying up of materials or corrosion of the inner wall. Use suitable cleaning agent, pay attention to avoid using chemicals that are corrosive to the kettle material.
External cleaning: Remove the dirt and dust on the outer wall of kettle body regularly to maintain good heat dissipation performance.
2.Inspection of seals
Regularly check whether the seals of the kettle (e.g. O-rings, gaskets) are intact, with or without aging, deformation or wear. Damage should be replaced in time to prevent leakage.
3.Fastener inspection
Check whether the fasteners of kettle body, stirrer, heating/cooling system and other parts are loose, and make sure all connections are tight and reliable.

Mixing System Maintenance

1.Agitator Inspection
Check the blades and shafts of the agitator for wear or deformation to ensure the mixing effect.
Regularly lubricate the bearings of the agitator to reduce friction and wear.
2.Motor and transmission
Check whether the motor runs smoothly, with no abnormal noise or vibration.
Regularly change the lubricating oil of the transmission device to maintain transmission efficiency.

Heating and Cooling System Maintenance

1.Heating element inspection
Check whether the heating elements (such as electric heating rods, steam heating tubes) are in good condition, with no leakage or breakage.
Regularly clean the accumulated dirt on the surface of the heating element to maintain good heat transfer efficiency.
2.Cooling system
Check whether the cooling water pipes are smooth to prevent blockage affecting the cooling effect.
Replace the coolant of the cooling system regularly to prevent corrosion and scaling.

Safety device check

1.Pressure gauge and thermometer
Regularly check the accuracy and sensitivity of pressure gauges and thermometers to ensure that they accurately reflect the pressure and temperature in the kettle.
2.Safety valves and rupture discs
Check whether the safety valve is working properly, and calibrate its opening pressure regularly.
Check whether the rupture disc is in good condition, with no cracks or deformation, to ensure that the pressure can be relieved in time when overpressure occurs.

Electrical System Maintenance

1.Cables and Junction Boxes
Check that cables and junction boxes are in good condition and are not broken or loose.
Keep the junction box dry to prevent moisture from the electrical components.
2. Control System
Regularly check the stability and reliability of the control system to ensure the accuracy of each control parameter.
Perform regular calibration and maintenance of the control system to ensure its normal operation.

Routine maintenance of the reaction kettle is a systematic and meticulous work, requiring operators to have a high degree of responsibility and professional skills. Through scientific and reasonable maintenance measures, it can ensure the long-term stable operation of the reactor and provide a strong guarantee for the safe production and efficient operation of the enterprise.
