How to maintain and upkeep a high viscosity vacuum filling machine?
Date: 2025-08-19Read: 34
1、 Daily basic maintenance and performance maintenance
1. System cleaning work
·All parts in contact with materials, including storage tanks, pipelines, pump chambers, and valves, should be thoroughly cleaned regularly to prevent blockage or contamination caused by residual high viscosity liquids.
·Use specialized cleaning agents or high-temperature steam for cleaning to ensure no dead corners are left.
2. Lubrication of moving parts
·Use high-temperature resistant and corrosion-resistant special lubricating oil for the transmission system and moving parts to reduce the additional friction load caused by high viscosity liquids.
·Check the lubrication status monthly and promptly replenish or replace it.
3. Replacement of key components
·Sealing rings, valve gaskets, O-rings and other vulnerable parts should be replaced regularly (recommended every 3 to 6 months) to prevent vacuum leakage caused by aging.
·When replacing, original or equivalent specifications of accessories should be selected to ensure sealing performance.
4. Calibration of Measurement and Vacuum Control
·Regularly calibrate the accuracy of the metering pump to ensure that the filling error is controlled within ± 0.5%.
·Check the set value of the vacuum control system to ensure its sensitivity and accuracy in response.
5. Electrical and sensor inspection
·Regularly inspect the vacuum sensor, control module, and circuit connection status, and promptly handle any abnormalities found.
·To avoid control system failure or misoperation caused by electrical faults.
6. Tightening of mechanical connectors
·Check the bolts, screws and other connecting components of each part of the equipment every week to prevent loosening caused by vibration and affect the stability of equipment operation.
2、 Special maintenance of vacuum system
1. Vacuum pump oil management
·First oil changeThe equipment must be replaced with new oil after running for 100 hours for the first time.
·Regularly change the oilReplace the vacuum pump oil every 2000 to 4000 hours of operation.
·Oil status monitoringDuring daily operation, it is necessary to observe whether the oil level is at the centerline position of the window; If the oil is found to be cloudy, emulsified, or contain metal particles, it should be replaced immediately.
2. Sealing and cleaning maintenance
·Clean the air inlet filter or dust prevention device of the vacuum pump every month to prevent dust from entering and affecting the vacuum effect.
·Focus on inspecting sealing components such as shaft seals and O-rings (about 60% of vacuum failures are caused by damaged seals), and replace them immediately if aging or damage is found.
3. Performance monitoring and deep maintenance
·Periodic maintenance：
·Perform basic cleaning (such as removing carbon deposits and sediments) every approximately 1000 hours of operation;
·Perform comprehensive disassembly inspection and maintenance every 3000 hours of operation.
·operation monitoring：
·Real time monitoring of bearing temperature, not exceeding 80 ° C;
·If there is abnormal noise or vibration, the machine should be stopped immediately to troubleshoot.
3、 Long term operation management strategy for equipment
1. Standardized operation training
·All operators must receive system training, master standard cleaning procedures, daily inspection points, and emergency shutdown operations.
·Improve operational standardization and reduce the risk of human error.
2. Develop a preventive maintenance plan
·Develop a detailed periodic maintenance plan based on the maintenance manual provided by the equipment manufacturer.
·All maintenance projects must be executed on time and recorded for subsequent analysis and fault prediction.
3. Control the operating environment
·The equipment should be installed in a dry environment with a relative humidity controlled below 85%.
·Avoid contact with corrosive gases in equipment to prevent the vacuum sealing system from being corroded and affecting its sealing performance.
4、 Summary
The maintenance focus of high viscosity vacuum filling equipment is:
·Regularly remove high viscosity residues;
·Timely replace key sealing components;
·Strengthen the oil management and sealing monitoring of vacuum pumps.
By implementing the structured and systematic maintenance plan mentioned above, the stability and filling accuracy of equipment operation can be significantly improved, ensuring product quality and sterility requirements.
