Isiqabu vana kwinkqubo ukufudumeza. Ukhetho zeesekethe, isimo sentlalo

Safety vana kwinkqubo zivula sisixhobo ukhuseleko umbane thermal kunye nezinye izixhobo ekulula ukuba isebenze. Owona msebenzi wayo - Hlela imithwalo ezingacwangciswanga nazo kwiimeko ezahlukeneyo.

Ngaphezu koko, ifowuni ukwenza ulawulo njengesipholisi flow kwinkqubo ukufudumeza. Zonke ezinye izixhobo kuyingozi kakhulu, ngenxa yokuba i ibhatyi kwamanzi ukunyuka koxinzelelo kugqalwa eyingozi.

ukuqashwa

Eyona njongo yale ivelufa ukhuseleko - kukhuselwe inkqubo zokufudumeza evela amathontsi uxinzelelo kunokwenzeka. Le meko kuvamile ukuba izindlu kwibhoyila ngomphunga. Inkqubo ukufudumeza amanzi kunye namanzi ashushu xi ifikelela amaxabiso kumda kunqabile.

Ukunyuka ngokukhawuleza xi kunokwenzeka ngenxa yezi zizathu zilandelayo:

• Umthamo we njengesipholisi engaphaya amaxabiso yokwakha ngenxa yokusilela ye matshini.
• Ukunyuka ngokukhawuleza lobushushu.

Isiqabu vana kwinkqubo zokufudumeza: scheme kwefowuni

Le fowuni iquka omzimba kunye izinto ezimbini ukubunjwa. Umzimba yenziwa ngobhedu itephu, iveliswayo iteknoloji sokunyathela eshushu. Le umba ophambili igesi umthombo ngentsimbi. Esebenzisa misela yayo, bazinzisa umkhosi xi apho uya kwenza inwebu overlying indlela ngaphandle.

Ngenxa yoko, i inwebu, leyo yesali, itywina igqityiwe, ukhuthazwa ngasemthonjeni. Inxalenye engentla ngasemthonjeni isekelwe ngokuchasene iqhoshana metal elihambisana intonga kwaye ziqinisiwe ukuba igqityezelwe ngesiphatho zeplastiki. Isiphatho iyafuneka ukuze alungise ivelufa uncedo uxinzelelo kwinkqubo ukufudumeza.

Makhe sihlolisise ngokweenkcukacha iindidi ezi zixhobo.

kokubonisa valve

Ezi zixhobo zenziwe ngobhedu. Olu hlobo kanye-ngayo, ngamanye amazwi, oko avulwa imikhosi uxinzelelo. Ngaphandle kokuba le ndlela ingenandleko, kuba nalo kakhulu oluthembekileyo. Kokubonisa valve ukhuseleko kwinkqubo zivula na isakhiwo esilula: stem gasket kunye namacala zombini - intambo.

Izixhobo sobhedu

Le mishini isakhiwo ezimbaxa ngakumbi. Kufuneka ifakwe kwinkqubo zokufudumeza ngoko nangoko emva pump kwegazi. Intonga nasentlakohlaza kule ebunjiweyo entle eyenziwe insimbi. valve ukhuseleko Brass kwinkqubo zivula uyakwazi ukumelana lobushushu njengesipholisi ukuya ku-1200 ° C.

hlola valve

Ivelufa check sisixhobo ukhuseleko onqanda sokuphuma of njengesipholisi kwinkqubo ukufudumeza kwi nethontsi loxinzelelo.

isimiso ukusebenza

iintlobo ezimbini eziphambili semigudu ingabonwa namhlanje - umthombo ngokobuzwe-kwempahla. Kwaye phambi kokuba enze kukhethwe ivelufa yokhuseleko inkqubo ubushushu, kuyimfuneko ukuba siqwalasele ezi ntlobo ngokweenkcukacha.

Lever-impahla

Olu hlobo isiqabu xi ivelufa ngaphandle itshixa isixhobo, ulwakhiwo apho ngumthwalo okhethekileyo kubangele ukuba kubekho ezinxulumene spool ngokusebenzisa lempumelelo. Ukuhambisa kwicala ubude ingalo umthwalo lilawula amandla ngayo isihlalo pridavlivaniya spool. Xa uxinzelelo njengesipholisi kwinkqubo zokufudumeza udlula mmiselo, ivelufa uncedo ivula, kunye ulwelo akufuneki aqukuqela iplagi.

spring

Okwangoku, eyona ethandwa entwasahlobo-uhlobo vana. Ukususela lwalo owandulelayo ungachazwa ukuba esikhondweni ivelufa hayi licinezelwe kunye lever kunye umthwalo, kwaye ngasemthonjeni. Umgaqo ukusebenza xa lulonke ayikho eyahlukileyo kakhulu ukusuka kwinkqubo yokuphatha lever-umthwalo. Xa angafaniyo izinga ucinezelo ye komnyaka, ulawulo vana.

obandayo ongakhetha

Ukuqinisekisa ukusebenza oluthembekileyo nangokhuseleko ivalve kwinkqubo zokufudumeza, kucetyiswa ufakelo ngokungqinelana nemigaqo. Uyakwazi ukuba sifumana i amaxwebhu ezikhethekileyo elawulayo. Imithetho bendawo kuxhomekeka kumthamo kunye nengcinezelo operating system. Kodwa ke imithetho zisekho, phakathi kwabo:

• Inkqubo ubushushu le fowuni kufuneka ifakwe kumgca flow the ngqo emva kwibhoyila. Ukuba thermal amandla generator mkhulu, iivelufa ezimbini ukuze ifakwe.
• A valve wokhuseleko kumbhobho ukubuya ubushushu ifakwe kuphela amanzi ashushu kwi kwindawo eziphezulu kwibhoyila.
• Kwakhona ukuvala engamkelekanga lomsele kwiindawo phakathi ngezilingo isixhobo vana lwezivalo engamkelekanga.
• Imibhobho Ukuchithwa kufuneka iboniswe kwinkqubo kwelindle okanye kwenye indawo ekhuselekileyo. Le ntambo ufakelo azamkeleki ngokupheleleyo izixhobo uvala.

Ukukhetha

Kubalulekile ukwenza ukhetho lasekunene ivelufa yokhuseleko inkqubo ubushushu, nto leyo ethintela kwibhoyila ukusuka abilayo kunye noxinzelelo lwegazi asezantsi. Ukuba ivelufa isebenza kakuhle, kufuneka:

• Khetha izixhobo spring, apho emthonjeni bude xi umelane njengesipholisi.
• Ukumisela ubungakanani kunye nohlobo isixhobo inkqubo zokufudumeza xi awudluli amaxabiso elivumelekileyo, ekubeni kufuneka ukunceda inkqubo.
• vula uhlobo vana kufuneka sikhetwe apho amanzi akhutshelwe emoyeni, wavala - xa amanzi akhutshelwa kumbhobho ukubuya.
• Full-lift ophakamisa ephantsi vana desirably ezikhethiweyo ngokusekelwe bandwidth.
• Xa siyeka amanzi emoyeni kucetyiswa ukuba ukuseta isixhobo open-hlobo. Kuba boilers usebenzisa amafutha elulwelo, kuyimfuneko ukuba ukukhetha kwemithambo ophakamisa ephantsi boilers gas - Full-lift.

yokubala

Ukubalwa isixhobo yokhuseleko kufuneka kwenziwe ngokungqinelana nenkqubo ebekwe phambili SNP II-35 "Boilers".

Ekubeni nabenzi akuvamanga kuchaziwe iinkcukacha ukuphakama yokwenene ngokuziphakamisa intonga, ekubaleni i parameter 1/20 isihlalo ubukhulu. Ngenxa yesi sizathu ubungakanani ivalve ngenxa yale ubalo thile eqolo. Xa kunjalo, emva kokukhetha esi sixhobo kufuneka thelekisa umthamo wobushushu kwenkqubo zokufudumeza kuphakanyisiwe kwimigaqo bobugcisa ukuze amandla iphezulu yisayizi ekhethiweyo.

Ukubeka ivelufa nokhuseleko kufuneka ukukhusela inkqubo ubushushu lingadluli inqanaba uxinzelelo phezu ixabiso umda. Ngenxa yesi sizathu, kubalwe le yunithi kufuneka incitshiswe nendlela ekubalwa ngayo ubuninzi ukwenyuselwa imali avumelekile njengesipholisi kunye nokuzimisela imithombo overpressure kunokwenzeka.

Imithombo yokukhula umthamo bangaba:

• Nobushushu kwi sokufudumeza okanye iyunithi kwibhoyila kunye vaporization elandelayo. Xa vaporization engamanzi uyakwazi ukwandisa umthamo wayo izihlandlo 461, ngoko ke le into xa ukhetha i vana lubalaseleyo.
• imigca output ulawulo oluzenzekelayo kwibhoyila make-up kunye neenkqubo ukufudumeza esizimeleyo akaphumeleli. Kwakhona unako ukukhonza njengomba nakolu ivelufa yokhetho.
• Le ubushushu itshiswe miso ubushushu okanye iyunithi kwibhoyila, kwandisa umthamo. Xa eshushu, ukunyuka ngqo kwi-mali ukusuka kwi-0 ukuya kwi-100 ° C, nto leyo-4% kuphela, ngoko ke ukhetho lobungakanani olu hlobo ifowuni ayikho ingongoma ebalulekileyo.

Izixhobo ezikhethiweyo ukunika isiqabu imali ebalwe of njengesipholisi ngalo mba ubalulekileyo ekukhuleni umthamo.

Safety vana kwinkqubo zokufudumeza: Ukukhetha

Netoti nombhojana wevalufa engenayo kufuneka ilingana no okanye inkulu ngaphezu umbhobho afunyenwe ukubala. Phezu kokuba bethe bayifezekisa le ubukhulu umlomo, kuyimfuneko ukuhlola isixhobo lokhuseleko kwakhona inzuzo abaliweyo umqulu njengesipholisi kwiimeko ezingxamisekileyo. Kwakhona kubalulekile ukuba uthathe ingqalelo into yokuba umahluko xi mkhulu phakathi amaxabiso kumgca lampompoza kunye nokuvulwa vana, ulwelo aza kukhululwa ngokusebenzisa izixhobo zokhuseleko.

Ukuchola isixhobo, oko kufuneka kukhunjulwe ukuba emnyango ngokupheleleyo ifunyanwa xa uxinzelelo kwinkqubo ubushushu ngaphezu ixabiso nezisabelayo kwi-10%, kunye nokuvalwa olupheleleyo - ngexesha ukuhla xi ngezantsi impendulo iparameter-20%. Ngako oko, kungakuhle ukuba ukhethe izixhobo xi iseti ngaphezulu malunga 20-30% yengcinezelo inkqubo eyiyo.

enobubanzi obungu

Izigqibo enobubanzi obungu izixhobo zokhuseleko yenziwa ngokusebenzisa iindlela ezizodwa sele iphuhlisiwe Gostekhnadzor. Ukuze ezi njongo, uyacebiswa ukumema abasebenzi abaqeqeshiweyo.

Ukuba oku akwenzeki kucetyiswa ukuba asebenzise umgaqo ilandelayo: kufuneka ibe ngaphantsi kwe kumbhobho lokuphuma unit kwibhoyila le ubukhulu vana. Kulo mzekelo, kratya kakhulu, nto leyo eza kuqinisekisa ukhuseleko nkqubo.

Ukubeka ivelufa ukhuseleko inkqubo zokufudumeza lwenziwa ngendlela yokuba uxinzelelo emandundu ngaphezu ezisebenza malunga ne10-15%. Ukusebenza lesixhobo zitshekishwe ngokubangela sisithethi sembeko. Ukulungisa ivelufa ukhuseleko kwenkqubo zokufudumeza kufuneka kwenziwa qho ngonyaka phambi kwexesha ubushushu.
