V. Operation and Maintenance Specifications
5.1 Operation Process (Standardized Steps)
Preparatory Work:
- Check if the equipment power supply matches (220V) and if the power cord is damaged.
- According to sieving requirements, select sieves with corresponding mesh counts, stack them in the order of “coarse mesh at the bottom, fine mesh at the top”, and a maximum of 9 layers can be installed.
- Clean the internal and external surfaces of the sieves to ensure no residual materials and avoid cross-contamination.
Sample Feeding:
- Weigh 0-100g of samples and evenly pour them into the topmost sieve, then close the sieve cover tightly.
- Adjust the equipment amplitude (0-3mm). For materials with poor fluidity, the amplitude can be appropriately increased (2-3mm), while for fine powder materials, a small amplitude (0.5-1mm) is recommended.
Startup and Operation:
- Press the start button, and the equipment will start automatic vibrating sieving. The conventional sieving time is 5-10 minutes (can be adjusted according to material characteristics).
- During operation, observe if the equipment has abnormal noise or shaking. If any abnormality is found, stop the machine immediately for inspection.
Completion and Cleaning:
- After sieving, turn off the power, remove the sieves layer by layer, collect the materials in each layer and weigh them for recording.
- Clean the equipment and sieves according to the “Daily Cleaning” requirements and organize the experimental data.
5.2 Maintenance System
| Maintenance Category | Maintenance Cycle | Specific Operations | Notes |
|---|---|---|---|
| Daily Cleaning | After each use | 1. Clean residual materials in the sieves with a soft brush (nylon material to avoid scratching the sieve mesh);
2. Blow off dust on the equipment surface and in gaps with an air blower; 3. Wipe the equipment shell with a dry soft cloth, and do not clean with water or organic solvents |
Do not use hard-bristled brushes or metal tools for cleaning to avoid damaging the sieve mesh;
For fine powder materials, cleaning in a fume hood is recommended to prevent dust diffusion |
| Drive Component Maintenance | Every 3 months (or after 50 uses) | 1. Open the motor end cover of the equipment and check the wear condition of the bearings;
2. Add special lubricating oil (3# lithium-based grease is recommended), with a grease addition of 0.5-1g each time; 3. Rotate the motor shaft to ensure uniform lubrication and no jamming |
Do not use inferior lubricating oil to avoid bearing corrosion;
Do not add excessive grease to prevent oil spillage from contaminating the equipment at high temperatures |
| Sieve Maintenance | After every 20 uses | 1. Check if the sieve mesh is damaged or deformed, and replace it in time if there is any problem;
2. Calibrate the sieve mesh accuracy with standard samples to ensure accurate sieving results; 3. When storing sieves, lay them flat or hang them vertically to avoid stacking and squeezing |
Do not continue to use damaged sieve meshes to avoid affecting analysis results;
National standard materials (such as standard glass beads) are recommended for calibration samples |
| Long-term Storage Maintenance | When not in use for more than 1 month | 1. Thoroughly clean the equipment and sieves to ensure no residual materials;
2. Apply a thin layer of anti-rust oil to the motor bearings and metal connectors of the equipment; 3. Cover the equipment with a dust cover and store it in a dry, well-ventilated environment free of corrosive gases (temperature 5-30℃, humidity ≤60%) |
Do not store in direct sunlight or near heat sources;
Before reuse, remove the dust cover, clean the anti-rust oil, and run it for 5 minutes to confirm normal operation |
