In the installation and construction phase, three core principles shall be strictly followed: accurate positioning, reliable sealing and standardized connection. During equipment positioning, the deviation between the centerline of air\u2011supply surface and the centerline of working\u2011zone equipment shall be \u2264\u202f50\u202fmm to prevent airflow misalignment and subsequent clean dead corners. For hoisting installation, the levelness error shall be \u2264\u202f3\u202fmm\/m, so as to avoid uneven stress on the plenum chamber and airflow deflection. Ceiling keels shall be reinforced in advance to meet the load\u2011bearing requirement of \u2265\u202f80\u202fkg\/\u33a1. Hoisting spacing shall be set in strict accordance with equipment specifications to eliminate potential deformation and loosening in later service.<\/p>\n

Equipment connection and sealing constitute the core key points of installation. When connecting with surgical shadowless lamps and other ceiling\u2011mounted devices, special mounting steel plates and sealing rubber rings shall be reserved to fill sealing gaps and prevent air leakage and dust accumulation. Pipeline interfaces and cabinet splicing gaps shall be fully sealed with food\u2011grade and medical\u2011grade sealing silicone to guarantee the tightness of the plenum chamber. For electrical and control system installation, interfaces for differential\u2011pressure sensors and resistance monitoring shall be reserved to realize real\u2011time monitoring of filter operating conditions. Meanwhile, circuits shall be treated with waterproof and dust\u2011proof measures to avoid electrical failures. Upon completion of installation, air pressure test, airflow uniformity inspection and tightness leak test shall be carried out. The equipment can be put into service only after all parameters meet requirements.<\/p>\n

During long\u2011term operation, air\u2011supply ceilings are prone to four typical faults: uneven air supply, excessive cleanliness index value, excessive operating noise and rapid filter clogging. Precise investigation and targeted solutions are required. First, uneven air supply and local clean dead corners are mostly caused by tilted installation, blocked flow\u2011equalizing plates or partial dust accumulation on filters. Countermeasures include calibrating equipment levelness, cleaning flow\u2011equalizing components and replacing failed filter elements. Second, continuously out\u2011of\u2011spec cleanliness mainly results from damaged filters, sealing air leakage or insufficient air\u2011change rate. Inspect sealing points one\u2011by\u2011one, perform filter integrity test and adjust fan rotating speed. Third, excessive operating noise is generally induced by loose fan assembly, plenum\u2011chamber resonance or airflow turbulence. Fasten fan components, install shock\u2011absorbing devices and trace the root cause of airflow disorder. Fourth, short\u2011term filter clogging is mainly attributed to invalid pre\u2011filtration or excessively high dust concentration in workshops. Replace pre\u2011filters and optimize the pre\u2011purification system of the workshop.<\/p>\n

\"\"<\/p>\n

Long\u2011term operation and maintenance shall establish a periodic standardized management system implemented in three dimensions: daily inspection, monthly maintenance and annual overhaul. Daily inspection focuses on monitoring operating noise, air\u2011supply velocity and differential\u2011pressure data, and recording changes of working conditions. Monthly maintenance covers cleaning primary\u2011efficiency filters, wiping flow\u2011equalizing plates and equipment housing, removing dust deposits inside the plenum chamber, and checking the integrity of sealing rubber strips. Annual overhaul includes full replacement of HEPA filters, fan\u2011performance testing, airflow\u2011parameter calibration and re\u2011inspection of equipment tightness. Meanwhile, a filter\u2011resistance early\u2011warning mechanism shall be established. Filter elements shall be replaced promptly when resistance reaches the threshold of 450\u202fPa to avoid purification failure caused by over\u2011service use.<\/p>\n

Strict implementation of installation specifications and O&M standards can effectively extend the service life of air\u2011supply ceilings, ensure stable airflow and qualified purification performance in clean spaces, and greatly reduce later\u2011stage fault\u2011repair costs. It provides long\u2011term and reliable terminal\u2011purification guarantee for scenarios such as clean workshops and medical operating rooms.<\/p>","protected":false},"excerpt":{"rendered":"

The purification performance and service life of air\u2011supply ceilings depend not only on the inherent technical quality of equipment, but also on standardized installation & construction, regular troubleshooting and scientific operation\u2011maintenance management. Mass practical engineering data show that more than 60% of cleanliness non\u2011compliance issues are caused by non\u2011standard installation and inadequate maintenance, which trigger faults such as air leakage, uneven air supply and filter element failure. Combined with Technical Code for Construction of Hospital Clean Operating Department and clean\u2011room construction standards, this paper sorts out complete installation specifications, common troubleshooting methods and long\u2011term O&M technical solutions.<\/p>","protected":false},"author":3,"featured_media":5814,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[92],"tags":[],"class_list":["post-5813","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-industry-technology"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.bacintl.com\/fr\/wp-json\/wp\/v2\/posts\/5813","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.bacintl.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.bacintl.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.bacintl.com\/fr\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bacintl.com\/fr\/wp-json\/wp\/v2\/comments?post=5813"}],"version-history":[{"count":2,"href":"https:\/\/www.bacintl.com\/fr\/wp-json\/wp\/v2\/posts\/5813\/revisions"}],"predecessor-version":[{"id":5818,"href":"https:\/\/www.bacintl.com\/fr\/wp-json\/wp\/v2\/posts\/5813\/revisions\/5818"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.bacintl.com\/fr\/wp-json\/wp\/v2\/media\/5814"}],"wp:attachment":[{"href":"https:\/\/www.bacintl.com\/fr\/wp-json\/wp\/v2\/media?parent=5813"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.bacintl.com\/fr\/wp-json\/wp\/v2\/categories?post=5813"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.bacintl.com\/fr\/wp-json\/wp\/v2\/tags?post=5813"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
