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
