The record management for the daily maintenance of the air supply ceiling is a crucial part for ensuring the stable operation of the equipment, tracing the root causes of problems, and optimizing maintenance strategies. The recorded content should be comprehensive, accurate, and traceable, and it should be linked with the overall operation archives of the cleanroom. It specifically includes the following six modules:
\nEquipment basic information module
\nCore parameters of the air supply ceiling: equipment model, factory serial number, installation location (such as XX workshop XX area of the cleanroom), rated air volume, matching filter specifications (initial efficiency \/ medium efficiency \/ high efficiency models, filtration efficiency, initial resistance).
\nMaintenance ledger number: unique ledger code compiled by year \/ area for easy archiving and retrieval.
\nDaily maintenance execution record module
\nMaintenance time: precise to year \/ month \/ day \/ hour, distinguishing daily inspections, weekly deep maintenance, monthly specialized maintenance, and quarterly sealingity tests.
\nMaintenance personnel: operator’s name, position, with signature confirmation, clearly defining the responsible party.
\nMaintenance content and results:
\nDaily inspection: fan operation status (no abnormal noise, vibration, stable rotation speed), diffuser plate sealing condition, surface cleaning areas and used tools (such as dust-free cloth + purification water).
\nWeekly \/ monthly maintenance: diffuser plate disassembly and cleaning situation, filter pressure difference monitoring values, seal ring status (no aging \/ need replacement), motor temperature detection results.
\nQuarterly maintenance: sealingity testing methods (smoke method \/ particle counting method), leakage point location and handling measures (such as special sealant sealing).
\nFull life cycle record module for core components (filters)
\nInstallation record of filters: installation date, production batch number, supplier information of initial efficiency \/ medium efficiency \/ high efficiency filters.
\nPressure difference monitoring trend record: real-time pressure difference values during each maintenance, ratio to the initial pressure difference, marking whether the pressure difference exceeds the standard (initial efficiency over 1.5 times, medium efficiency over 2 times, high efficiency over 2-3 times).
\nFilter replacement record: replacement reason (pressure difference exceeds standard \/ filter damage \/ cleanliness not up to standard), replacement date, disposal method of discarded filters (sealed packaging \/ hazardous waste transfer number), sealing verification results after installation of new filters.
\nFault handling and abnormal record module
\nAbnormal phenomena: time of equipment failure occurrence, specific manifestations (such as sudden drop in air volume, abnormal noise, inspection of cleanliness exceeding standards).
\nTroubleshooting process: analysis of fault causes (such as filter blockage \/ fan bearing wear \/ seal ring aging), tools and methods used for troubleshooting.
\nHandling measures and results: maintenance steps (such as replacing fan bearings \/ replacing high-efficiency filters), equipment operation parameters after maintenance (air volume, pressure difference, cleanliness values), whether it returns to normal operation.
\nPreventive measures: optimization plans formulated for faults (such as shortening maintenance cycle for certain types of filters \/ increasing frequency of fan inspections).
\nVerification record after maintenance module
\nVerification data after startup: pressure difference stability data of the fan after 10-15 minutes of operation, cleanliness values of the air supply area inspected by the dust particle counter (must comply with the corresponding cleanroom grade standards).
\nVerification personnel: name of the inspector, verification date, attached inspection report number.
\nLedger management information module
\nAudit record: auditor and audit date of the ledger to ensure the record is true and accurate.
\nMaintenance cycle adjustment: record the basis for adjustment of the maintenance cycle (such as in areas with high dust concentration, change from weekly cleaning to every 5 days cleaning).
\nRetention period: clearly define the retention period of the ledger (generally no less than 1-3 years, or in accordance with industry regulations \/ customer audit requirements).<\/p>","protected":false},"excerpt":{"rendered":"
