Chopozera mpira wagalasi ndiye chinthu chofunikira kwambiri chomwe chimatha kutenthedwa ndi kutentha mu makina opopera.Mpira wagalasi umadzazidwa ndi mayankho achilengedwe okhala ndi ma coefficients osiyanasiyana okulitsa.Pambuyo pakukula kwamafuta pazitentha zosiyanasiyana, mpira wagalasi umasweka, ndipo madzi otuluka mupaipi amawapopera mpaka m'mathirewo amitundu yosiyanasiyana, mmwamba, pansi kapena m'mbali, kuti akwaniritse cholinga chowaza.Imagwiritsidwa ntchito pamakina opangira ma sprinkler system m'mafakitole, zipatala, masukulu, malo ogulitsira makina, mahotela, malo odyera, malo achisangalalo ndi zipinda zapansi zokhala ndi kutentha kwa 4 ° C ~ 70 ° C.
Galasi mpira sprinkler
1. Wowaza mpira wagalasi ndiye chinthu chofunikira kwambiri chomwe chimakhudzidwa ndi kutentha mu makina opangira madzi.Mpira wagalasi umadzazidwa ndi mayankho achilengedwe okhala ndi ma coefficients osiyanasiyana okulitsa.Pambuyo pakukula kwamafuta pazitentha zosiyanasiyana, mpira wagalasi umasweka, ndipo madzi otuluka mupaipi amawapopera mpaka m'mathirewo amitundu yosiyanasiyana, mmwamba, pansi kapena m'mbali, kuti akwaniritse cholinga chowaza.Imagwiritsidwa ntchito pamakina opangira ma sprinkler system m'mafakitole, zipatala, masukulu, malo ogulitsira makina, mahotela, malo odyera, malo achisangalalo ndi zipinda zapansi zokhala ndi kutentha kwa 4 ° C ~ 70 ° C.
2. Mfundo yogwirira ntchito: mpira wagalasi wa sprinkler wa galasi umadzazidwa ndi organic solution ndi high coefficient of thermal expansion.Pa kutentha kwa chipinda, chigoba cha mpira chikhoza kunyamula mphamvu inayake yothandizira kuonetsetsa kuti chosindikizira chikugwira ntchito.Pakayaka moto, yankho la organic limakula ndi kuwonjezeka kwa kutentha mpaka thupi lagalasi litasweka ndipo mpando wa mpira ndi chisindikizo zimatsukidwa ndi madzi pambuyo potaya chithandizo, kuti muyambe kukonkha kuzimitsa moto.
3. Mawonekedwe apangidwe: chopopera cha galasi chotsekedwa chimapangidwa ndi sprinkler mutu, mpira wa galasi lamoto, splash pan, mpando wa mpira, chisindikizo ndi seti screw.Pambuyo podutsa zinthu zonse zowunikira ndi kuyesa zitsanzo monga kuyesa kusindikiza kwa 3Mpa, phula lokhazikika limakhazikika ndi zomatira ndikuperekedwa kumsika.Sichiloledwa kuphwanyidwa kapena kusinthidwa pambuyo pa kukhazikitsa.
Kuyankha mwachangu koyambirira kozimitsa moto
Kukhudzika kwa zinthu zomwe zimakhudzidwa ndi matenthedwe mu makina opopera odziwikiratu ndi mtundu wa kuyankha mwachangu.Kumayambiriro kwa moto, sprinkler ochepa okha ayenera kuyambika, kotero kuti pangakhale madzi okwanira kuti achitepo kanthu mwamsanga pa sprinkler kuzimitsa moto kapena kuletsa kufalikira kwa moto.Ili ndi mawonekedwe anthawi yoyankhira matenthedwe othamanga komanso kutulutsa kwakukulu kotsitsira, Imagwiritsidwa ntchito makamaka pazinthu zodziwikiratu zamakina opopera monga malo osungiramo zinthu okwera ndi malo osungiramo zinthu zamakampani opanga zinthu.
Mfundo ya kamangidwe: nozzle yoyambirira ya kuponderezedwa mwachangu (ESFR) imapangidwa makamaka ndi thupi la nozzle, mpando wa mpira, gasket zotanuka, kuthandizira, mbale yoyika, kusindikiza gasket, splash pan, mpira wa galasi lamoto ndi zomangira.Nthawi wamba, mpira galasi moto wokhazikika pa nozzle thupi ndi oblique fulcrum monga thandizo, malo mbale ndi kusintha zomangira, ndi kuyesedwa hydrostatic kusindikiza 1.2MPa ~ 3Mpa.Pambuyo pa moto, mpira wa galasi lamoto udzayankha mofulumira ndikumasula pansi pa kutentha, mpando wa mpira ndi chithandizo zidzagwa, ndipo madzi ochuluka adzaponyedwa m'malo otetezera, kuti azimitsa moto ndikuletsa. moto.
Chowaza chobisika
Chopangidwacho chimapangidwa ndi mphuno ya mpira wagalasi (1), mpando wa mikono yowononga (2), mpando wakuvundikira wakunja (3) ndi chivundikiro chakunja (4).Nozzle ndi screw socket zimayikidwa pa payipi ya network ya chitoliro pamodzi, ndiyeno chivundikirocho chimayikidwa.Chivundikiro chakunja m'munsi ndi chivundikiro chakunja ndi welded mu lonse ndi fusible aloyi.Pakayaka moto, kutentha kozungulira kukakwera ndikufika posungunula fusible alloy, chivundikiro chakunja chimangowonongeka.Ndi kuwonjezeka kosalekeza kwa kutentha, mpira wa galasi la nozzle pachivundikirocho udzasweka chifukwa cha kukula kwa madzi okhudzidwa ndi kutentha, kuti ayambe kupopera madzi okha.
Fusible alloy fire sprinkler
Chogulitsachi ndi chowaza chotsekedwa chotsegulidwa ndi kutentha ndi kusungunuka kwa fusible alloy elements.Monga mpira wagalasi wotsekedwa, umagwiritsidwa ntchito kwambiri ngati njira yodziwira kutentha kwa makina opopera opepuka komanso apakatikati monga mahotela, nyumba zamalonda, malo odyera, malo osungiramo zinthu komanso magalasi apansi panthaka.
Magwiridwe magawo: m'mimba mwake mwadzina: dn15mm kulumikiza ulusi: R "ovoteledwa ntchito kuthamanga: 1.2MPa kusindikiza chisindikizo mayeso kukakamiza: 3.0MPa otaya khalidwe koyenelera: k = 80 ± 4 mwadzina ntchito kutentha: 74 ℃± 3.2 ℃ mankhwala muyezo: gb5133.1-200 unsembe mtundu: y-zstx15-74 ℃ kuwaza poto pansi
Kapangidwe kake ndi mfundo yogwirira ntchito: Chogulitsachi chimapangidwa ndi chimango cha nozzle, mpando wosindikizira, gasket yosindikizira, mbale yoyikapo, mpando wagolide wosungunula, manja osungunuka agolide ndi chithandizo, mbale ya mbedza ndi aloyi ya fusible.The fusible alloy pakati pa golide woyengedwa ndi manja amasungunuka chifukwa cha kutentha kwa moto pakakhala moto, zomwe zimachepetsa kutalika pakati pa golide wosungunula ndi manja, ndipo mbale yoyikirapo imasiya kuthandizira. madzi akutuluka pampando wosindikiza kuti ayambe kukonkha kuzimitsa moto.Pansi pa madzi ena oyenda, chizindikiro choyendetsera madzi chimayambira pampu yamoto kapena valavu ya alamu kuti ayambe kutulutsa madzi, ndikupitiriza kupopera kuchokera pamphuno yotsegulidwa, kuti akwaniritse cholinga chozimitsa moto.
