Risk of failure due to dust and oil mist
Fire and burn accidents
Dust inside a high-temperature panel can lead to serious accidents
In workplaces with a lot of dust, paper dust, welding fumes, oil mist, etc., these particles can penetrate deep into panel. Once inside panel it is difficult to thoroughly clean and remove the dust and oil mist. Furthermore, there is an increased risk of fire or burnout inside panel due to adhesion to high-temperature parts such as power semiconductors and capacitors in inverters, servo amplifiers, and power supply supply units, or sparks from electromagnetic switches.
Substrate with heavy dust accumulation
Burn marks on the coil on power supply board
Spark marks on the IC leads of control board
Contact malfunction/short circuit accident
Oil intrusion can cause electrical system problems.
If dust or oil gets into panel, the contacts of relays and electromagnetic switches may stick, preventing normal contact operation and signal input/output, causing machinery to stop or malfunction, leading to unexpected problems and line shutdowns.Furthermore, because oil is conductive, adhesion or falling onto electrical circuits can cause malfunctions and short circuits.
Oil enters through the intake and exhaust ports of fans, etc.
Breakers and electromagnetic switches covered in oil and dust
Short circuit caused by oil on the board surface
