As a precision chemical equipment, the maintenance and upkeep of the lifting glass reactor directly affect the equipment's lifespan and experimental safety. The following are maintenance points summarized based on professional practice, covering daily inspections, cleaning standards, accessory management, and operating taboos.
1、 Daily inspection and operation monitoring
Appearance and sealing inspectionBefore each use, check the glass kettle body for cracks, scratches, or bubbles to avoid the risk of rupture caused by defects. At the same time, confirm that sealing components such as sealing rings and flange interfaces are intact to prevent leakage.
Running status monitoringListen to the equipment for any abnormal vibration or noise during operation, observe whether the mixing shaft rotates smoothly (ensuring clockwise operation), and regularly check whether the temperature and pressure instruments are sensitive to prevent over limit operation.
Lubrication and fastening maintenanceRegularly lubricate moving parts such as reducers and bearings to maintain normal oil levels; Check if bolts, clamps, and other fasteners are loose, and promptly reinforce them to reduce equipment shaking.
2、 Cleaning and drying standards
Cleaning methodImmediately clean the inner wall with a soft bristled brush and neutral cleaning agent after the experiment. For stubborn residues, soak them in compatible solvents and gently treat them. It is strictly prohibited to soak in strong acids and alkalis for a long time to prevent corrosion of glass or sealing materials.
Drying requirementsAfter cleaning, air dry naturally or blow dry with clean compressed air to avoid rust or pollution caused by residual water stains. When stored for a long time, it is recommended to disassemble the accessories and store them in a dry environment. Apply vacuum grease to the glass interface to prevent adhesion.
3、 Accessory management and replacement cycle
Inspection of vulnerable partsCheck vulnerable parts such as sealing rings, mixing blades, valves, etc. every 3-6 months. If aging, deformation, or loss of elasticity is found, replace them immediately to prevent leakage caused by seal failure.
Principles for selecting accessoriesChoose materials that are temperature resistant and corrosion-resistant (such as PTFE sealing rings) to ensure compatibility with the reactants. Avoid excessive tightening during installation to prevent glass components from breaking.
4、 Operation taboos and safety points
Precautions for feedingIt is strictly prohibited to carry metal or hard debris in the material to avoid hitting the kettle body; Reduce temperature difference when adding materials to prevent glass stress cracking caused by thermal shock.
Temperature controlDuring heating, the heating rate should be controlled within 5 ℃ per minute, and sudden cooling should be avoided during cooling to reduce thermal stress damage to the glass.
Principles of fault handlingWhen there is a blockage in the discharge, use non-metallic tools to clear it, and it is strictly prohibited to knock or strike hard; If abnormal pressure or temperature is found during operation, immediately stop the machine for troubleshooting and prohibit operation under pressure.
5、 Long term storage recommendations
Idle equipment should be thoroughly cleaned and dried, and disassembled parts should be stored separately; Regularly power on and inspect the motor and control system to prevent moisture or component aging. Establish equipment usage logs to record maintenance time and abnormal situations for easy traceability and management.
By standardizing operations and regular maintenance, the service life of the lifting glass reactor can be significantly extended, ensuring experimental safety and data reliability. Daily maintenance should be integrated into the workflow and form institutionalized habits.
