Case Study – Improved performance with hood modifications
Isuues
- Dust source is far away, and the external hood is not capturing all the generated dust.
- It is difficult to move the hood closer to the dust source because it affects work.
Case Study – Reviewing from centralized dust collection to individual dust collection
Isuues
- Can centralized dust collection be used to reduce cross-contamination between processes?
- It is difficult to adapt to line changes due to increased airflow caused by additional equipment.
- Dust tends to accumulate in the dust collection duct.
Case Study – An accident occurred due to a duct falling
Isuues
- An accident occurred due to a duct falling
- Reduced dust collection rate due to piping blockage
- Dust accumulation in the duct increases the weight of the piping, causing damage and falling
Case Study – Unstable operation due to insufficient airflow
Isuues
- Insufficient Suction
- Duct Clogging (Blockages)
- Excessive Suction at Specific Points
Case Study – Regular self-inspection of dust collectors
Isuues
- Multiple dust collectors are used, so inspections take days.
- Inspection manpower is unavailable due to ancillary equipment.
Case Study – Preventing Sparks from Entering the Dust Collector
Isuues
- Sparks are generated from the dust source and are directly sucked in.
- Sparks may enter through the hood, raising concerns about a dust collector fire.
Case Study – Reduces dust collector filter load
Isuues
- Increased dust volume causes discharge problems (dust residue inside the machine and dust scattering during discharge).
- Increased dust volume leads to poor dust removal from the filter.
Case Study – Detecting signs of filter replacement using a dust monitor
Isuues
- Eliminating the risk of dust leaks from dust collectors
- Nearby residents complained about an outdoor dust collector being accidentally discarded
- Detecting signs of dust collector exhaust leaks in advance
Case Study – Improve suction efficiency with an adjustable hood
Isuues
- Fixed hoods cannot capture dust particles far from the hood.
- Dust generation location changes depending on the work content.
