Izicupho zezitimu ezisebenza ngomshini zisebenza ngokucabangela umehluko wokuminyana phakathi kwesitimu ne-condensate. Bazodlula emiqulu emikhulu ye-condensate ngokuqhubekayo futhi bafanele uhla olubanzi lwezinhlelo zokusebenza zenqubo. Izinhlobo zifaka izicupho zesitimu sebhakede elintantayo kanye ne-inverted.

I-Ball Float Steam Traps (Ama-Mechanical Steam Traps)

Izicupho ezintantayo zisebenza ngokuzwa umehluko phakathi kwe-steam ne-condensate. Endabeni yesicupho esiboniswe esithombeni esingakwesokudla (umgibe wokuntanta one-valve yomoya), i-condensate efinyelela ogibeni ibangela ukuthi i-float iphakame, iphakamise i-valve esihlalweni sayo futhi ibangele ukwehla.

Izicupho zesimanje zisebenzisa izimbobo zokulawula, njengoba kukhonjisiwe esithombeni esingakwesokudla (Izicupho Ezintantayo NgamaVenti Okulawula). Lokhu kuvumela umoya wokuqala ukuba udlule ngenkathi isicupho siphatha i-condensate.

I-automatic vent isebenzisa ukuhlanganiswa kwesinye sokucindezela okulinganiselwe okufana ne-regulator steam trap, etholakala endaweni yesitimu ngaphezu kwezinga le-condensate.

Lapho kukhishwa umoya wokuqala, uhlala uvaliwe kuze kube yilapho umoya noma amanye amagesi angafinyeleli aqoqana ngesikhathi sokusebenza okuvamile futhi avulwe ngokunciphisa izinga lokushisa lomoya/umusi.

Imbobo yesilawuli inikeza inzuzo eyengeziwe yokuthuthukisa kakhulu umthamo wokujiya ngesikhathi sokuqala kwamakhaza.

Esikhathini esidlule, uma kwakukhona isando samanzi ohlelweni, i-vent yokulawula yayinezinga elithile lobuthakathaka. Uma isando samanzi sinzima, ngisho nebhola lingase liphuke. Kodwa-ke, ezicupheni zesimanje zokuntanta, indawo yokungena ingaba yinto ehlangene, enamandla kakhulu yonke i-capsule yensimbi engagqwali, futhi amasu esimanje wokushisela asetshenziswa ebholeni enza yonke into entantayo iqine kakhulu futhi ithembeke ezimweni zesando samanzi.

Ngandlela thize, isicupho se-thermostatic esintantayo siyinto eseduze nesicupho esiphelele somusi. Kungakhathaliseki ukuthi ingcindezi ye-steam ishintsha kanjani, izokhishwa ngokushesha ngangokunokwenzeka ngemva kokukhiqizwa kwe-condensate.

Izinzuzo ze-Float Thermostatic Steam Traps

Isicupho sikhipha i-condensate ngokuqhubekayo ezingeni lokushisa lomusi. Lokhu kwenza kube ukukhetha okuyinhloko kwezinhlelo zokusebenza lapho izinga lokudlulisa ukushisa kwendawo eshisiwe enikeziwe liphezulu.

Iphatha imithwalo ye-condensate emikhulu noma elula ngokulinganayo futhi ayithinteki ukushintshashintsha okubanzi nokungalindelekile kwengcindezi noma ukugeleza.

Uma nje i-automatic ifakiwe, isicupho sikhululekile ukukhipha umoya.

Ngosayizi wayo, lokho kuyikhono elingaphezu kobukhulu.

Inguqulo ene-valve yokukhulula i-steam lock iyona kuphela isicupho esifaneleka ngokugcwele kunoma yisiphi isikhiye sesitimu esimelana nesando samanzi.

Nakuba kungenakuthinteka njengezicupho zamabhakede ahlanekezelwe, izicupho zentanta zingalinyazwa izinguquko zesigaba esinodlame, futhi uma zifakwa endaweni eveziwe umzimba oyinhloko kufanele ubambezeleke, futhi/noma wengezwe ngesicupho esincane sokulungiswa kokukhipha amanzi.

Njengazo zonke izicupho zemishini, isakhiwo sangaphakathi esihluke ngokuphelele siyadingeka ukuze sisebenze phezu kobubanzi bengcindezi eguquguqukayo. Izicupho eziklanyelwe ukusebenza ngengcindezi ephakeme ehlukile zinezimbobo ezincane zokulinganisa ukunyakaza kokuntanta. Uma isicupho singaphansi kwengcindezi ephakeme yokuhluka kunokulindelekile, izovala futhi ingadluli i-condensate.

Ama-Bucket Steam Traps (Ama-Mechanical Steam Traps)

(i) Umgqomo uyacwila, udonsa ivalve esihlalweni. I-Condensate igeleza ngaphansi kwebhakede, igcwalise ibhakede, futhi igeleze nge-outlet.

(ii) Ukufika kwe-steam kuntanta umgqomo, obese uyakhuphuka futhi uvale indawo yokuphuma.

(iii) Isicupho sihlala sivaliwe kuze kube yilapho isitimu esisebhakedeni sijiya noma siphuma amabhamuza ngembobo yokukhipha umoya siye phezulu emzimbeni womgibe. Bese liyacwila, lidonse ingxenye enkulu yevalvu esihlalweni sayo. I-condensate eqoqiwe ikhishwa futhi umjikelezo uyaqhubeka.

Ku-(ii), umoya ofinyelela esicupheni ekuqaleni uzohlinzeka ngokukhuphuka kwebhakede futhi uvale i-valve. Imbobo yebhakede ibalulekile ukuvumela umoya ukuba ubaleke uye phezulu kwesicupho ukuze uphume ekugcineni ngezihlalo eziningi zamavalvu. Ngezimbobo ezincane nokuhluka kokucindezela okuncane, izicupho azisheshi ekukhipheni umoya. Ngesikhathi esifanayo, kufanele idlule (futhi ngaleyo ndlela ichithe) inani elithile le-steam ukuze isicupho sisebenze ngemva kokusulwa komoya. Ama-parallel vents afakwe ngaphandle kwesicupho anciphisa isikhathi sokuqalisa.

Izinzuzo zeIzicupho ze-Bucket Steam Steam

Isicupho sesitimu sebhakede esihlanekezelwe sadalelwa ukumelana nomfutho ophezulu.

Kufana nesiteyi se-thermostatic esintantayo, sibekezelela kakhulu izimo zesando samanzi.

Ingasetshenziswa kulayini we-steam oshisa kakhulu, wengeze i-valve yokuhlola ku-groove.

Imodi yokwehluleka kwesinye isikhathi iyavuleka, ngakho iphephe kakhudlwana ezinhlelweni ezidinga lokhu kusebenza, okufana nokukhipha amanzi enjini.

Ububi be-Inverted Bucket Steam Traps

Ubuncane bembobo engaphezulu kwebhakede busho ukuthi lesi sicupho sizokhipha umoya kancane kakhulu. Imbobo ayikwazi ukukhuliswa njengoba isitimu sizodlula ngokushesha okukhulu ngesikhathi sokusebenza okuvamile.

Kufanele kube namanzi anele emzimbeni wesicupho ukuze asebenze njengophawu eduze komphetho webhakede. Uma isicupho silahlekelwa uphawu lwaso lwamanzi, isitimu siyachithwa ngevalvu yokuphuma. Lokhu kungenzeka kaningi ezinhlelweni lapho kuba khona ukwehla kungazelelwe kwengcindezi yesitimu, okubangela ukuthi enye i-condensate emzimbeni wesicupho “ikhanye” ibe isitimu. Umphongolo uphelelwa amandla nokucwila, okwenza isitimu esisha sidlule emigodini yokukhala. Kuphela uma i-condensate eyanele ifinyelela ogibeni lwesitimu lapho ingavalwa khona amanzi futhi ukuze kuvinjwe imfucumfucu yesitimu.

Uma isicupho sebhakede esihlanekezelwe sisetshenziswa esicelweni lapho kulindeleke khona ukuguquguquka komfutho wezitshalo, ivalvu yokuhlola kufanele ifakwe emugqeni wokungena ngaphambi kogibe. I-steam namanzi kungageleza ngokukhululekile ngendlela ekhonjisiwe, kuyilapho ukugeleza okubuyela emuva kungenakwenzeka ngoba i-valve yokuhlola icindezelwe esihlalweni sayo.

Izinga lokushisa eliphezulu lesitimu esishisa kakhulu lingabangela isicupho sebhakede esihlanekezelwe ukuba silahlekelwe uphawu lwaso lwamanzi. Ezimweni ezinjalo, i-valve yokuhlola eyandulela isicupho kufanele ibhekwe njengebalulekile. Zimbalwa kakhulu izicupho zamabhakede ezihlanekezelwe ezikhiqizwa “nge-valve yokuhlola” edidiyelwe njengejwayelekile.

Uma isicupho sebhakede esihlanekezelwe sishiywa sobala eduze ne-sub-zero, singalinyazwa ukuguqulwa kwesigaba. Njengezinhlobo ezahlukene zezicupho zemishini, ukwahlukanisa okufanele kuzokunqoba lokhu kushiyeka uma izimo zingezimbi kakhulu. Uma izimo zemvelo ezilindelekile zingaphansi kukaziro, khona-ke kunezicupho eziningi ezinamandla okufanele zicatshangelwe ngokucophelela ukwenza umsebenzi. Endabeni yokudonsa okuyinhloko, isicupho esiguqukayo se-thermos singaba yisinqumo esiyinhloko.

Njengomgibe wokuntanta, ukuvuleka kwesicupho sebhakede esihlanekezelwe kuklanyelwe ukuthwala ukuhluka kwengcindezi enkulu. Uma isicupho singaphansi kwengcindezi ephakeme yokuhluka kunokulindelekile, izovala futhi ingadluli i-condensate. Itholakala ngebanga losayizi we-orifice ukumboza inqwaba yezingcindezi.
