Core Principles: Electrical explosion-proof priority, static electricity not lost effectiveness, filters replaced on time, eliminate spark\/static electricity hazards, balance clean function and explosion-proof safety.
\nI. Daily Maintenance (Daily\/Shift)
\nAppearance and cleaning
\nUse dust-free cloths to wipe the inner walls, nozzles, door bodies, and glass. Do not use steel wool or sharp tools to avoid scratching and generating metal debris and friction sparks.
\nClean the dust on the bottom return grille to keep the return air unobstructed and avoid dust accumulation.
\nElectrical safety inspection (explosion-proof focus)
\nCheck the explosion-proof indicator light, emergency stop button, and infrared sensor for normal operation. Check if the explosion-proof junction box is sealed properly, without looseness, damage, or oil stains.
\nCheck the grounding line: the grounding wire of the box is not loose or rusted, and the grounding resistance meets the explosion-proof requirements.
\nOperation status inspection
\nStart the test for the fan, spray shower, and double-door interlock function. The two doors cannot be opened simultaneously.
\nListen for any abnormal sounds from the fan, and stop immediately if there are abnormal sounds to prevent the fan blade from rubbing the shell and generating sparks.
\nStatic electricity inspection
\nNo loosening of nozzles and stainless steel panels to avoid shaking and static electricity generation; keep the ground and spray shower room dry to reduce static accumulation.
\nIi. Weekly maintenance
\nThoroughly clean the surface dust of the primary filter, which can be washed or vacuumed. Replace it if it is severely clogged.
\nCheck the nozzles: adjust the angle, clear the blockage, and ensure smooth air supply; tighten the nozzle screws, and there should be no looseness.
\nCheck the door seals, explosion-proof door locks, and hinges, clean and apply anti-rust lubricating oil to ensure sealing and smooth opening and closing.
\nCheck the explosion-proof cables, conduit pipes, and sealing joints, without damage or looseness to prevent combustible gas from entering the electrical chamber.
\nIii. Monthly maintenance
\nTest the spray shower wind speed: standard 25\u201330m\/s. If the wind speed is low, check if the primary or secondary filter is clogged, or if the fan is faulty.
\nCheck the fan motor: the explosion-proof motor operates normally, without overheating, odor, or abnormal sounds.
\nOverall grounding test, static electricity performance test, to ensure no static electricity hazards.
\nCheck the control panel, explosion-proof switch, and interlock system, calibrate the spray shower time.
\nIv. Quarterly\/Semi-annual Maintenance
\nPrimary filter: generally replace every 3\u20136 months, for dust-laden lithium battery and chemical workshops, shorten to 2\u20133 months.
\nSecondary filter: replace every 6\u201312 months; If the pressure difference exceeds the standard, the wind speed drops significantly, or the PAO leak detection fails, it must be replaced.
\nReplacing the secondary filter requires stopping the machine and disconnecting the power supply. Strict explosion-proof power-off operation is required. Do not attempt to disassemble while powered on.
\nCompletely tighten all explosion-proof electrical connectors\uff0c grounding terminals\uff0c and box screws.
\nClean the dust inside the fan blades and static pressure box to prevent the risk of dust accumulation and spontaneous combustion.
\nV. Annual Major Overhaul and Maintenance
\nReplace all filters as a set\uff0c conduct leak testing for the secondary filter.
\nDisassemble and maintain the explosion-proof motor\uff0c add lubricating oil to the bearings\uff0c and check the insulation performance.
\nComprehensively inspect the corresponding components of the explosion-proof certificate to strictly prohibit the use of non-explosion-proof accessories.
\nRemove rust from the box\uff0c apply sealant\uff0c check the sealing performance\uff0c and perform rust maintenance with 304\/316 stainless steel.
\nIssue annual maintenance\uff0c grounding\uff0c wind speed\uff0c and explosion-proof test records.
\nVi. Special Maintenance Taboos for Explosion-proof Safety (Very Important)
\nDo not privately modify the electrical system\uff0c replace ordinary non-explosion-proof fans\uff0c switches\uff0c sensors.
\nDo not open the explosion-proof junction box\uff0c control box while powered on. Must disconnect the power and hang a sign.
\nDo not use ordinary tools to strike or collide the box forcefully to prevent sparks.
\nDo not stack miscellaneous items or flammable substances inside. Do not smoke or use fire in the spray shower room.
\nIn dust explosion environments (lithium battery\uff0c aluminum powder)\uff1a Clean the dust daily\uff0c and prohibit excessive dust accumulation.
\nVii. Simple Handling of Common Faults
\nFan does not start\uff1a check if the explosion-proof emergency stop is pressed\uff0c power supply\uff0c interlock signals\uff0c and explosion-proof motor faults.
\nWind speed decreases\uff1a clogging of the primary or secondary filter\uff0c dust accumulation on the fan blade\uff0c unstable voltage. Doors not interlocked: explosion-proof electromagnetic lock failure, loose wiring, abnormal controller.
