Isebenza kanjani i-vacuum switch? (Isiqephu nezinzuzo)
Okuqukethwe
Njengabanikazi abaningi bezindlu, cishe awazi ukuthi i-vacuum breaker isebenza kanjani. Nakhu ukubuka konke okusheshayo kwalokho ekwenzayo nokuthi ikwenza kanjani.
I-vacuum breaker isebenza njenge-valve yokuhlola evamile. Umoya ovela ngaphandle ungangena ohlelweni ngokungena komoya. Kodwa i-vacuum breaker ivaleka unomphela lapho amanzi noma isitimu sizama ukubaleka.
Ngizongena imininingwane eyengeziwe ngezansi.
Ungayisebenzisa kanjani i-vacuum breaker?
Isibonelo esilandelayo sibonisa indlela yokusebenzisa kahle i-vacuum breaker ohlelweni lwe-steam nokuthi kungani uyidinga.
Cabanga ngendlela lokhu okudluliselwa ngayo:
Sine-steam kusuka ku-boiler ku-10 psi noma kancane. Okulandelayo kuza i-valve yokulawula, egijima ngepayipi iye phezulu kwesishintshi sokushisa.
Sinomugqa wokujiya oholela esicupheni somusi. Amanzi adlula kuvalvu yokuhlola angene ohlelweni lwethu lokubuya kwe-condensate emkhathini.
Ngakho-ke, uma i-valve yokulawula ivuliwe ngokugcwele, kunomehluko omncane wokucindezela phakathi kwe-valve kanye nomshini wokushisa. Kepha sizobona ukuthi ukwehla kwengcindezi lapha kusanele ukusunduza i-condensate esicupheni sokuqala futhi konke kusebenza kahle.
Njengoba umkhiqizo ongaphakathi kwesishintshi sokushisa uqala ukushisa, ivalvu yethu yokulawula izoshintsha iye phansi, ukuze ukwazi ukubona ingcindezi iqala ukwehla.
Ngaphezu kwalokho, kuzoba nengcindezi encane emgqeni we-condensate. Uma ingcindezi ye-condensate kufanele ibe phezulu ukuze isunduze i-condensate esicupheni, noma uma kukhona ukushintshashintsha okwengeziwe ku-valve yokulawula, okungase kubangele ukugeleza emuva kusishintshi sokushisa, noma okubi nakakhulu, kudale i-vacuum, izinkinga zizovela.
Lokhu kungabangela izinkinga ngokulawulwa kwezinga lokushisa kolayini, isando samanzi, amandla okuba yiqhwa, noma ukugqwala kwesistimu yethu ngokuhamba kwesikhathi, ngakho le nkinga idinga ukubhekwana ne-vacuum breaker.
Ake sithi sibeka i-vacuum breaker phambi kwesishintshi sokushisa bese sivula le valve. Kulokhu, uzozwa umoya ophuma ngaphandle ungena ku-vacuum breaker futhi uzokwazi ukubuka igeji isuka ku-vacuum pressure iye ku-zero, ikhombisa ukuthi akukho ngcindezi ohlelweni.
Singakwazi ukuhlala ngaphansi kweziro, ngisho noma sinengcindezi enhle, noma sehlele kuqanda. Manje, uma sibeka isicupho sethu ngamayintshi angu-14 kuya kwangu-18 ngaphansi kwesishintshi sethu sokushisa, singahlala sinikeza ukucindezela okuhle. Uma i-vacuum breaker ifakwe kahle, sizoba ne-drainage enhle.
Yenzani i-vacuum circuit breaker?
Ngakho-ke, ukufingqa okuhle, nazi izizathu ezi-4 eziphezulu zokuthi kungani kufanele ube ne-vacuum breaker ohlelweni lwakho:
- Lokhu kusiza ukuqinisekisa ukuthi yonke i-condensate ikhishwa kuzo zombili izindlela zokuvala kanye nezokumodulating.
- Lokhu kuzokuvikela esando samanzi.
- Lokhu kwenza izinga lokushisa lizinze futhi mancane amathuba okuthi lingashintsha.
- Lokhu kuzosiza ukugwema ukonakala kokudla.
Isebenza kanjani i-vacuum switch?
Ngokuvamile, i-vacuum breaker ine-disc yepulasitiki ekhishwa ukucindezela kwamanzi futhi ivale izimbobo ezincane ze-vent. Uma umfutho wokunikezela wehla, i-disc ibuyela emuva, ivule izimbobo zokungenisa umoya futhi ivimbele amanzi ukuthi abuyele emuva.
Ikamelo elingena umoya liyavuleka lapho umfutho womoya udlula umfutho wamanzi. Lokhu kuphazamisa ukumunca okubangelwa umfutho ophansi futhi kuvimbela amanzi ukuthi abuyele emuva. Ngaphambi kokuba amanzi afinyelele kuma-valve okufafaza, i-vacuum breaker ifakwa eduze nomthombo wamanzi.
Kufanele usibeke ngaphezu kwendawo ephakeme kakhulu yesistimu, ngokuvamile ngaphezu kwekhanda lokufafaza, okuwumthambeka ophakeme kakhulu noma ophakeme kakhulu egcekeni.
Kungani kudingeka i-vacuum circuit breaker?
Ukungcoliswa kwamanzi kungaba nemiphumela eminingi ehlukene, ngakho ukukuvimba kubalulekile. Amakhodi amaningi okwakha endawo asho ukuthi zonke izinhlelo zamapayipi zidinga isivimbeli sokubuyela emuva.
Njengoba imizi eminingi inamanzi awodwa okuphuza kanye nezinye izinhloso ezihlanganisa ukuchelela, kuhlale kunethuba lokungcola ngokuxhumanisa.
Ukubuyela emuva kungase kwenzeke uma umfutho wamanzi kumthombo omkhulu wamanzi wekhaya wehla ngokuzumayo. Isibonelo, uma amanzi edolobha ephela nganoma yisiphi isizathu, lokhu kungase kubangele ukucindezela okuphansi emanzini amakhulu asekhaya.
Ngokucindezela okungalungile, amanzi angageleza ngakolunye uhlangothi ngamapayipi. Lokhu kubizwa ngokuthi i-siphoning. Nakuba kungenzeki kaningi, kungabangela amanzi aphuma emigqeni yokufafaza ukuthi avuze emanzini amakhulu. Ukusuka lapho, angagcina esemanzini asekhaya lakho.
Yiziphi izinhlobo ze-vacuum circuit breaker nokuthi zisebenza kanjani?
Kunezinhlobo eziningi ezahlukene zeziphazamisi ze-vacuum. Ama-atmospheric vacuum breaker yiwona avame kakhulu.
Ama-vacuum breakers ase-atmospheric
I-atmospheric vacuum breaker (AVB) iyisisetshenziswa sokuvimbela ukugeleza emuva esisebenzisa isimbobo somoya kanye nevalvu yokuhlola ukuze kuvinjelwe uketshezi olungaphuzwa ukuthi lumuncelwe kabusha emanzini aphuzwayo. Lokhu kubizwa ngokuthi i-back siphoning, okubangelwa ukucindezela okungalungile kumapayipi okunikezela.
I-Pressure Vacuum Breakers
I-Pressure Vacuum Breaker (PVB) iyingxenye ebalulekile yezinhlelo zokunisela. Ivimbela amanzi ukuthi angabuyeli emuva esuka ohlelweni lwakho lokunisela angene emthonjeni wamanzi ahlanzekile wasekhaya, okungamanzi akho okuphuza.
I-pressure vacuum breaker iqukethe idivayisi yokuhlola noma i-valve yokuhlola kanye nomoya ongenisa umoya okhipha umoya emkhathini (umoya ovulekile). Ngokuvamile, i-valve yokuhlola iklanyelwe ukuvumela amanzi ukuba adlule kodwa ivimbele indawo yokungena komoya.
Imibuzo evame ukubuzwa
Kungani i-vacuum breaker ibalulekile?
I-vacuum breaker ibalulekile ngoba ivimbela amanzi ukuthi agelezele emuva. Ukugeleza emuva kungenza uhlelo lwakho lokuchelela kanye namapayipi amanzi lungasebenzi kahle ngokuvumela amanzi nokugeleza kugelezele emuva esikhundleni sokuya phambili. Lokhu kungethula amagciwane ayingozi emapayipini nasezintweni zakho. Ngakho-ke, i-vacuum breaker iyingxenye ebalulekile yokuvimbela ukungcola.
I-vacuum breaker ikuvimbela kanjani ukugeleza emuva?
I-vacuum breaker imisa ukugeleza emuva ngokuphoqa umoya ungene ohlelweni, okudala umehluko wengcindezi. Ngokunokwenzeka, amanzi azohamba aye emoyeni ophoqelelwe. Uma amanzi egeleza kwelinye icala, ubungeke ube khona umehluko ekucindezelweni, ngakho-ke umoya ophoqeka emapayipini ubungaphushwa udlule kuma- molecule amanzi.
Yiziphi izidingo zekhodi zama-vacuum circuit breakers?
I-vacuum switch iyadingeka kunoma iyiphi indawo lapho amanzi esetshenziselwa izinjongo ngaphandle kokuphuza. Imithetho yezwe neyenhlangano ithi izinqamuli ze-vacuum kufanele zifakwe kompompi bangaphandle, iziwashi zokugeza izitsha ezithengiswayo, ompompi be-mop, kanye nompompi bohlobo lwe-hose dish spray.
