To ensure the stable performance and service life of magnetic lifters, focus on the following three key maintenance tasks, covering daily cleaning, regular inspections, and storage management.
- Cleaning the Magnetic Surface
The cleanliness of the magnetic surface directly affects adsorption performance, so regular cleaning is essential.
- Cleaning Frequency: Clean after each use or at least once a week. For harsh working conditions (e.g., dusty or oily machine shops), increase the frequency.
- Cleaning Method: Wipe the surface with a dry, soft cloth or brush to remove dust, oil, and iron filings. For stubborn oil stains, use a small amount of neutral detergent (e.g., diluted dish soap), then dry thoroughly with a clean cloth. Avoid strong acids or alkalis, as they may damage the surface.
- Precautions: Do not use hard tools like steel wool or sandpaper. These can scratch the magnetic surface, creating gaps that reduce adsorption efficiency.
- Regular Performance Inspections
Timely inspections help identify potential issues early and prevent safety risks from performance degradation.
- Inspection Focus: First, test the adsorption force with small ferromagnetic objects (e.g., nails, bolts). If local adsorption is significantly weaker, magnetic force attenuation may have occurred. Second, check the magnet’s appearance for cracks, damage, or detachment. If the magnet is abnormal, stop using the lifter immediately.
- Inspection Frequency: Inspect once every 1–2 months for regular use. For long-term, high-load operations (e.g., 8+ hours of continuous daily use), shorten the interval to once every 2 weeks.
- Standardized Storage Management
Storage conditions during idle periods impact equipment life, so strict storage rules must be followed.
- Environmental Requirements: Store in a dry, cool indoor area. Avoid outdoor storage or placement near water sources (e.g., sinks, damp walls) and heat sources (e.g., heaters, furnaces). This prevents rust from moisture and magnet aging from high temperatures.
- Storage Method: Place the lifter on a non-magnetic stand (e.g., wooden or plastic) to avoid long-term contact with other iron objects. For extended idle periods (over 1 month), apply a thin layer of anti-rust oil to non-magnetic metal parts for extra protection.
