As a key equipment in industries such as pharmaceuticals and chemicals, the maintenance details of ultrasonic bottle washing machines directly affect equipment performance, service life, and cleaning effectiveness. The following systematically elaborates on the maintenance points from the aspects of daily maintenance, regular maintenance, operating standards, safety precautions, etc.:
1、 Daily maintenance details
1. Cleaning solution management
-Regular replacement: The cleaning solution should be replaced according to the plan to avoid affecting the cleaning effect due to pollution or aging. When replacing, it is necessary to drain the residual liquid and inject new liquid to two-thirds of the height of the tank (to avoid overfilling and affecting ultrasonic transmission).
-Water level monitoring: It is strictly prohibited to turn on ultrasonic waves or water pumps before reaching the specified water level. During production, the water level should be replenished at any time to prevent damage to the transducer caused by idle operation.
-Water quality requirements: Before use, it is necessary to check whether the spray system for non saline water, injection water, etc. is normal, ensure that the water quality meets the standards, and avoid clogging the nozzle or corroding the equipment.
2. Equipment cleaning
-External cleaning: Wipe the equipment casing daily to keep it free of dust and oil stains; Regularly inspect the internal tank, clean up debris or broken bottle residue, and prevent clogging of the filter screen.
-Spray system maintenance: After each wash change, rinse the spray arm and filter cartridge, unclog the nozzle, and check if it is aligned to avoid uneven cleaning due to blockage.
3. Power and mechanical inspection
-Circuit safety: Check the power cord daily for damage, ensure stable voltage, and avoid overload operation.
-Lubrication of transmission components: Lubricating grease needs to be added to the bearings of the bottle inlet system and outlet track every shift; Lubrication of components such as chain box drive shaft should be done once every two shifts to reduce friction losses.
-No load test run: Run idle for 2 minutes before starting up to confirm that there are no abnormal sounds in the motor and transmission structure, and that the frequency converter parameters are set reasonably (such as frequency 10-26Hz).
2、 Regular maintenance plan
1. Key component inspection
-Transducer maintenance: Check the fasteners of the ultrasonic transducer for looseness every six months, measure whether the frequency is consistent with the host, and avoid energy efficiency decline due to frequency deviation.
-Seal replacement: Check the sealing ring of the groove body, replace it in a timely manner when it ages or deforms, to prevent liquid leakage or ultrasonic energy loss.
2. Deep cleaning and dredging
-Tank cleaning: Brush the cleaning tank quarterly to remove attached dirt or scale, especially in ultrasonic vibration blind spots.
-Pipeline maintenance: High pressure spray cleaning of water and gas pipelines is carried out annually to ensure no risk of cross contamination and compliance with GMP requirements.
3. Mechanical structure debugging
-Chain tension: Check the tension of the conveyor chain, bottle wheel and other chains every six months, adjust them to the appropriate tension, and avoid bottle jamming or derailment.
-Calibration of bottle wheel: Regularly check the position of the bottle wheel clutch to ensure smooth bottle transfer and reduce the risk of bottle tipping or breakage.
3、 Operating standards and safety precautions
1. Prohibit illegal operations
-It is strictly prohibited to start ultrasonic waves or water pumps before reaching the water level to avoid damaging the oscillator under no-load conditions.
-It is prohibited to use strong acid/strong alkali cleaning agents. Neutral or weak acid weak alkali solutions should be preferred to reduce corrosion to the tank and transducer.
2. Processing after production is completed
-When shutting down, it is necessary to first turn off the ultrasonic waves and then drain the cleaning solution to prevent residual liquid from corroding the equipment.
-Clean up broken bottles and debris, check whether the bottle wheel, track and other components are intact, and prepare for the next production.
3. Environmental control
-The equipment should be placed in a dry and ventilated place to avoid electrical components rusting or short circuiting in a humid environment.
-Cut off the power after work and maintain the equipment after it has cooled down to prevent burns or accidental contact.
4、 Recording and troubleshooting
1. Maintenance records: Establish maintenance logs to record the content of each maintenance, replacement of parts, and abnormal situations, for easy tracking of equipment status.
2. Fault response: If the ultrasonic does not work or the bottle is stuck, the machine should be stopped immediately and professional maintenance personnel should be notified. Do not disassemble it by yourself.
The maintenance of ultrasonic bottle washing machines should be combined with daily cleaning, regular maintenance, standardized operation, and environmental management. Through refined maintenance, the equipment life can be extended to ensure cleaning quality and production safety.
