The maintenance and upkeep of small laboratory airflow crushers should be combined with daily operations and periodic inspections. The specific methods are as follows:
1、 Key points of daily maintenance
1. Cleaning management
Thoroughly clean the crushing chamber, inlet/outlet, and filter residue after each use to prevent material accumulation from affecting air flow efficiency.
Clean the surface of the equipment with a soft cloth or compressed air to avoid chemical solvents corroding the components.
(Additional attention should be paid to the cleaning of heat sinks and ventilation openings in summer)
2. Lubrication and fastening
Regularly check the lubricating oil status of moving parts such as bearings and gears, and shorten the oil change cycle during high temperature seasons.
Confirm that all fasteners (such as blade screws, pipe connections) are not loose, and high-speed rotating parts need to be inspected with emphasis.
2、 Key component maintenance
1. Monitoring of vulnerable parts
Regularly check the wear of the blades and grading wheels, and control the weight difference to ≤ 1g when replacing the hammer blades symmetrically.
The screen mesh should be replaced immediately if it is damaged or deformed, and the flatness and sealing should be ensured during installation.
2. Electrical system maintenance
Check if the insulation layer of the circuit is aging, and strengthen the moisture-proof treatment of the control cabinet in humid environments.
Test the effectiveness of safety switches, emergency stop devices, and other functions.
3、 Periodic deep maintenance
1. System check
Clean the air ducts and permanent magnet tubes of iron impurities every month to prevent blockages from affecting the crushing efficiency.
Calibrate the speed and airflow parameters of the grading wheel to ensure stable particle size distribution.
2. Long term maintenance strategy
Establish maintenance files to record the replacement component model and maintenance time.
If the shutdown exceeds one week, the residual materials in the pipeline should be emptied to prevent clumping.
4、 Suggestions for operating standards
1. The material needs to be dry and free of metal impurities, and the feeding speed should be uniform to avoid overload.
2. Stop the machine immediately for abnormal vibration or response, and prohibit operation with defects.
Note: During maintenance, it is necessary to strictly refer to the equipment manual parameters, as different models may have special requirements.
