The following is forHigh pressure microjet homogenizerA practical guide for equipment maintenance and upkeep, combined with daily operating standards, periodic maintenance, and fault prevention, helps users extend equipment life and improve operational stability:
1、 Daily maintenance: prevent problems before they happen
Pre-start inspection
Pipeline and seals: Check whether the connection between the feed pipe, homogenization valve, and high-pressure cylinder is loose or aged, to avoid leakage or pressure loss.
Cooling system: Confirm that the cooling water circulation is smooth and the water temperature is ≤ 30 ℃ to prevent deformation of the sealing ring or damage to the motor due to overheating.
Power and grounding: Check voltage stability (± 5% rated value), ensure good grounding, and avoid electrical faults.
runtime monitoring
Pressure fluctuation: If the pressure gauge reading is abnormal (such as a sudden drop), immediately stop the machine and check if the homogenization valve is blocked or if the seal has failed.
Material status: Observe the uniformity of the material at the discharge port. If particle aggregation or stratification occurs, it may be necessary to adjust parameters or clean the homogenization valve.
Noise and vibration: Abnormal noise may be caused by bearing wear or loose components, and should be promptly shut down for maintenance.
Cleaning after shutdown
Immediate flushing: Use purified water or 75% ethanol to circulate and flush the pipeline for 10-15 minutes to prevent material residue from solidifying and blocking.
Interaction chamber disassembly: Disassemble the interaction chamber once a week and clean the sediment on the inner wall with a soft bristled brush to avoid corrosion or scratches.
Drying treatment: After cleaning, blow dry the pipeline with compressed air to prevent residual water stains from causing microbial growth.
2、 Periodic maintenance: Extend the lifespan of core components
Lubrication and Sealing
Gearbox lubrication: Replace the gear oil (recommended ISO VG 320) every 3 months, and keep the oil level at 1/2-2/3 of the viewing window.
Sealing ring replacement: The high-pressure cylinder sealing ring should be replaced every 500 hours or when there is a leak, using a material compatible with the material (such as polytetrafluoroethylene).
Inspection of vulnerable parts
Homogenization valve: Check the wear of the valve core every 1000 hours, and replace it immediately if there are pits or cracks on the surface.
Check valve: Disassemble and clean it monthly, check the elasticity of the spring, and prevent reverse leakage from causing damage to the pump body.
Electrical system maintenance
Touch screen calibration: Use calibration tools to test touch accuracy every six months to avoid operational errors.
Line inspection: Check the power cord and sensor connection wire for damage every year, and replace aging cables.
3、 Long term disuse and storage: moisture and corrosion prevention are key factors
Thoroughly clean: Rinse the equipment with 65% ethanol circulation to remove all residual liquids.
Moisture proof treatment: Place desiccants in the interaction chamber and high-pressure cylinder, and wrap them with dust-proof film on the outer layer.
Regular start-up: If the shutdown exceeds one month, power on and run for 10 minutes every month to prevent component corrosion or lubricant solidification.
4、 Quick troubleshooting: 5-minute problem location
| phenomenon | Possible reasons | Solution |
| The pressure cannot reach the set value | Homogenization valve blockage, pump body leakage | Disassemble and clean the homogenization valve, check the sealing ring |
| The discharge temperature is too high | Insufficient cooling water flow and excessive material viscosity | Increase cooling water flow rate and reduce feed concentration |
| Touch screen unresponsive | Static interference, system crash | Restart the device and check the grounding wire |
| Motor overheating alarm | Cooling fan malfunction, high load | Clean up fan dust and reduce operating pressure |
5、 Maintenance Misconceptions and Precautions
Disable hard object cleaning: Avoid using wire brushes or metal tools to clean the interaction chamber to prevent scratching the inner wall.
Material compatibility: Acidic or corrosive materials need to be neutralized with alkaline solution in advance to prevent aging of the sealing ring.
Parameter recording: Establish equipment operation logs to record data such as pressure, temperature, maintenance time, etc., for easy traceability of issues.
Original accessories: When replacing core components such as sealing rings and valve cores, priority should be given to using the original model to avoid compatibility issues.
6、 Three core principles for extending lifespan
Prevention is better than maintenance: By conducting daily inspections, potential hazards can be identified in advance to prevent small problems from escalating into major malfunctions.
Cleaning is maintenance: Thoroughly cleaning after each use can reduce the risk of pipeline blockage by more than 80%.
Data driven maintenance: Analyze component lifespan based on operational logs and develop personalized maintenance plans.
Implementation effect:
Regular maintenance can extend equipment lifespan by 30% -50% and reduce failure rates by over 60%.
A certain biopharmaceutical company has extended the overhaul cycle of the high-pressure micro jet homogenizer from 2 years to 4 years by strictly implementing this plan, saving approximately 120000 yuan in annual maintenance costs.
Through systematic maintenance and upkeep, the high-pressure micro jet homogenizer can maintain efficient and stable operation for a long time, creating higher production value for users.
