| ＞300 | 48 | 52 |
Amandla aqhutshwa kabili wenqubomgomo nobuchwepheshe asheshise ukuthuthukiswa okuthulile. Ngakolunye uhlangothi, izindinganiso zikazwelonke ezintsha ziye zaqinisa imingcele yomsindo wemishini yesiqandisi yezentengiselwano, ebeka ngokucacile ukuthi umsindo osebenzayo wamakhabethe aqondile esiphuzo esiphuzo esisodwa kufanele ulawulwe ngaphansi kwama-decibel angu-42. Ngakolunye uhlangothi, ukuthandwa kobuchwepheshe befrikhwensi eguquguqukayo kanye nezakhiwo ezihlakaniphile zokunciphisa umsindo kuye kwehlisa ngokuqhubekayo umkhawulo wezindleko wempahla enomsindo ophansi. I-Nenwell yenze ama-decibel angu-38 aba izinga lemishini yayo eyinhloko, futhi amanye amamodeli asezingeni eliphezulu aze afinyelele izinga elithulile “lezinga lomtapo wolwazi” lama-decibel angu-35. Uchungechunge lwe-LSC luwumkhiqizo omele ozalwe kulo mkhuba
I. Izingozi Eziningi Zomsindo Kumakhabhinethi Amile Esiqandisini
Umthelela ongemuhle womsindo ezimeni zezentengiselwano udlula kude “ukungezwani kokuzwa” futhi usuphenduke izindleko zokusebenza ezinganakwa. Ngokombono wokuhlangenwe nakho kwamakhasimende, inhlolovo eyenziwa esitolo esithengisa izinto ezithengwayo ibonisa ukuthi lapho umsindo wekhabethe elifakwe esiqandisini udlula ama-decibel angu-40, isilinganiso sesikhathi sokuhlala kwamakhasimende sifinyezwa ngo-23%, futhi izinga lokuthenga kabusha lehla15%. Ukubhuza okuqhubekayo kungabangela ukucasuka okuncane, ikakhulukazi ezitolo zezitolo ezigcizelela ukuzizwisa.
Kubasebenzi, izingozi zezempilo zokuchayeka isikhathi eside ezindaweni ezinomsindo zidinga ukunakwa okwengeziwe. Ucwaningo olwenziwa yi-World Health Organization (WHO) lubonisa ukuthi ukuchayeka isikhathi eside endaweni engaphezu kwama-decibel angu-45 kungaholela ezinkingeni ezinjengokukhuphuka kwezinga lokuzwa nokunganaki. Omabhalane bezitolo ezitholakala kalula bachayeka emsindweni wamakhabethe afakwe esiqandisini amahora angaphezu kwangu-8 ngosuku. Uma okokusebenza kungavinjelwa umsindo, amathuba okulimala kokuzwa emsebenzini aphakeme ngokuphindwe kathathu kunalawo omphakathi jikelele.
Umsindo ungase futhi usebenze “njengesignali eyisixwayiso sangaphambi kwesikhathi” ngokwehluleka kwezisetshenziswa. Umsindo wekhabethe elisebenza esiqandisini elisebenza ngokujwayelekile ubonakala ngemisindo esezingeni eliphansi. Uma imisindo ebukhali engavamile noma ukubhonga okuphakathi kwenzeka ngokuzumayo, ngokuvamile kubonisa izinkinga ezifana nokujam kwe-compressor cylinder noma ukugqokwa kwe-fan bear. Idatha evela ochungechungeni lokuphekela ikhombisa ukuthi u-80% wokwehluleka kwekhabhinethi eqandisiwe kwandulelwa umsindo ongajwayelekile, futhi ukulahleka kwaminyaka yonke kokonakala kwesiphuzo ngenxa yokunganaki izimpawu zomsindo kubalelwa emashumini ezinkulungwane zama-yuan.
II. Ukulandelela Umthombo: Imithombo Emihlanu Eyinhloko Yomsindo Emakhabetheni Amile Esiqandisini
1. I-Compressor: “I-Dominant Contributor” Kumsindo
"Njengenhliziyo" yesistimu yesiqandisi, umsindo osebenzayo we-compressor ubala ngaphezu kuka-70% wengqikithi yomsindo wemishini. Uma i-fixed-frequency compressor iqala futhi ima, umthelela wokusebenza phakathi kwepiston nesilinda udala umsindo omkhulu osheshayo. Ngisho nangesikhathi sokusebenza okuzinzile, umsindo we-electromagnetic kanye nokuhanjiswa kokudlidliza kokusebenza kwemoto kudala ukuphazamiseka okuqhubekayo. Uma i-compressor ingashaqeki ngesikhathi sokufakwa, ukudlidliza kuzokhuliswa ngekhabhinethi, okuholela “ekubhongelweni kwe-resonant.”
2. Amafeni nama-Air Ducts: Imithombo Enganakiwe Yomsindo We-Aerodynamic
Ukusebenza kwamafeni emakhabetheni amile afakwe esiqandisini apholile emoyeni kudala izinhlobo ezimbili zomsindo: enye iwumsindo we-vortex owakhiwa ama-blade anqamula emoyeni, kanti enye umsindo onomsindo obangelwa ukungqubuzana phakathi kokugeleza komoya nezindonga zamapayipi omoya. Ukuhlolwa kwe-Shanghai Jiao Tong University kuthola ukuthi uma igebe phakathi kwephuzu le-fan blade kanye nepayipi lomoya lingaklanywanga ngendlela efanele, lizodala ukugeleza komoya, kukhuphule amandla omsindo womsindo ngo-15%. Ngemva kokuthuthukisa, umsindo ezindaweni ezithile zokulinganisa ungancishiswa ngama-decibel angu-5.79. I-3D circulation air duct eyamukelwe uchungechunge lwe-LSC iwumklamo olungiselelwe kahle wale nkinga.
3. Ukugeleza Kwesiqandisi: “Imisindo Engajwayelekile” Ithambekele Ekwahlulelweni Okungalungile
Lapho isiqandisi sizungeza epayipini, uma i-radius egobayo yepayipi incane kakhulu noma ivinjiwe, izokhipha umsindo wokugeleza "wokuguquguquka". Lo msindo ubonakala ikakhulukazi esigabeni sokuqala sokuqaliswa kwemishini futhi ngokuvamile ubhekwa kabi njengephutha abasebenzisi. Ngaphezu kwalokho, ukucindezela okungavamile kwesiqandisi kungabangela ukudlidliza kwamapayipi, kuzwakale kukhabhinethi futhi kukhiphe umsindo wefrikhwensi ephansi.
4. Isakhiwo seKhabhinethi: “Umgodi Ozwakalayo” Okhulisa Umsindo
Uma ikhabethe lenziwe ngezinto ezisezingeni eliphansi njengamapuleti ensimbi amancane, ukudlidliza kwe-compressor kanye ne-fan kuzojabulisa i-resonance yekhabhinethi, ikhulise umsindo izikhathi ezingu-2-3. Kweminye imikhiqizo, ngenxa yokulungiswa kwamapayipi okuxekethile, ipayipi lishayisana nekhabhinethi ngesikhathi sokusebenza, likhiqiza imisindo “yokucofa” ngezikhathi ezithile. Nakuba izinga le-decibel lalo msindo lingekho phezulu, ukhahlo lwawo luwudlula kude umsindo wokusebenza okushelelayo
5. Ukufakwa kanye Nendawo: Ngemuva kokufaka Ama-Noise Inducer
Isitezi esingalingani siwumthombo womsindo ovame kakhulu wangemuva kokufakwa. Lapho ikhabethe eliqandisiwe libekwe nge-engeli, isisekelo se-compressor sigcizelelwa ngokungalingani, siqinisa umsindo wokudlidliza. Uma ikhabhinethi ibekwe eduze kwezindonga noma ezinye izinto zokusebenza, umsindo uzobekwa phezulu ngokuqhutshwa okuqinile nokucabangela, okwenza inani elilinganisiwe libe ngama-decibel angu-3-5 ukuphakama kunendawo evamile. Ngaphezu kwalokho, ukubeka izinto phezulu kudala “i-resonator,” okuguqula ukundindizela kwemishini kube imisindo esobala engavamile.
III. Ukuncishiswa Komsindo Okugcwele: Izisombululo Ezihlelekile ukusuka ku-Design to Use
1. Idizayini Ethule Yezingxenye Eziyinhloko
Ukukhethwa kwe-I-compressor iyisisekelo somsindoukunciphisa. Uma uchungechunge lwe-LSC lisebenzisa i-variable frequency compressor, lungagwema ukuqala nokuma njalo ngokulungisa isivinini sokuzungeza, ukunciphisa umsindo wokusebenza8-10ama-decibel. Uma kubhangqwe namaphedi abamba ukushaqeka aphansi kanye nabakaki abamisiwe, kunganciphisa90%ukudluliswa kokudlidliza. Ifeni kufanele yamukele imodeli ethulile ene-blade curvature, enegebe lethiphu ye-blade elilawulwa ngaphakathi kwamamilimitha angu-0.5. Ngesikhathi esifanayo, ngesistimu yokulawula isivinini ehlakaniphile, isivinini sokuzungeza singancishiswa ngokuzenzakalelayo ebusuku
2. Ukwenza ngcono kwe-Acoustic kwamaKhabhinethi kanye neMibhobho Yomoya
Izimbobo ezimunca umsindo ezimise okwekhekheba lezinyosi kanye nokotini ovimba umsindo ophakeme kakhulu kufanele kufakwe ngaphakathi kwekhabhinethi. Lesi sakhiwo singamunca okungaphezu kwalokho30% of umsindo wemishini. I-compressor compartment yamukela idizayini emunca umsindo enamagumbi amaningi, futhi ukuvuleka kungalawuleka ngokuzenzakalelayo ngokwenani lomsindo ngokusebenzisa izimbobo ezimunca umsindo ezilungisekayo, ukuncishiswa komsindo okulinganisayo nokusebenza kahle kokukhipha ukushisa. Umnyango wengilazi ophikisana nenkungu wochungechunge lwe-LSC awugcini nje ngokuthuthukisa umphumela wokubonisa, kodwa isakhiwo sawo sesemishi singaphinda uvimbele umsindo othile wangaphakathi ukuthi ungasabalali ubheke ngaphandle.
3. Ukufakwa Okujwayelekile kanye Nezinqubo Zokulungisa Amaphutha
Ngesikhathi sokufakwa, izinga kufanele lisetshenziswe ukulinganisa ikhabhinethi ukuze kuqinisekiswe amandla afanayo kuwo wonke amakhona amane. Amaphedi okumunca irabha kufanele engezwe esisekelweni uma kudingeka. Ibanga elingamasentimitha ayi-10-15 kufanele ligcinwe phakathi kwekhabhinethi nodonga ukuze kugwenywe ukubonakaliswa komsindo. Uma zibekwe ezindaweni ezinomsindo kalula njengendawo yaphansi yokhuni, amaphedi avikela umsindo angabekwa ukuze kunqandwe ukudluliswa kokudlidliza. Phakathi nesigaba sokulungisa amaphutha, ukulungiswa kwamapayipi kufanele kuhlolwe, futhi imikhono yenjoloba yebhafa kufanele yengezwe ezingxenyeni ezixegayo.
4. Amasu Okulawula Umsindo Okugcinwa Kwansuku zonke
Ama-fan blade kufanele ahlanzwe masonto onke ukuze kuvinjelwe ukuphazamiseka kwebhalansi okuguquguqukayo okubangelwa ukunqwabelana kothuli. Ukunqwabelana kothuli lwe-1-gram kuma-blades kungakhuphula umsindo ngama-decibel angu-3. Ama-compressor fasteners kufanele ahlolwe njalo ngenyanga, futhi izikulufa ezixegayo kufanele ziqiniswe ngesikhathi esifanele. Ama-fan bearings kufanele agcotshwe njalo ngekota ukuze kuncishiswe umsindo wokungqubuzana. Lapho kutholwa imisindo engavamile “yokugigiyela”, ukuvuza kwesiqandisi noma izinkinga zokuvaleka kwamapayipi kufanele ziphenywe ngokushesha ukuze kuvinjwe inkinga ukuba ingabi yimbi.
5. Ukunciphisa Umsindo Onamandla Wezinhlelo Ezihlakaniphile
Amamodeli asezingeni eliphezulu angahlonyiswa ngezinzwa zomsindo namasistimu okulawula ahlakaniphile ukuze aqaphe amanani omsindo ngesikhathi sangempela. Uma umsindo udlula ama-decibel angu-38, unciphisa ngokuzenzakalelayo isivinini se-compressor noma ulungise igiya labalandeli. Uma uchungechunge lwe-LSC lunemodi yokonga amandla ebusuku, ibanga lokulawula izinga lokushisa linganwetshwa ngamahora angewona awebhizinisi, kwehliswe umthwalo wokusebenza kwesisetshenziswa futhi ngenxa yalokho kwehliswe umsindo ngamadecibel angu-5-6.
