Ngaphambi kokuqonda lokhu okuqukethwe, sidinga ukwazi ngaphansi kwaziphi izimo lapho kufanele sithathe izinyathelo zokuvala izimo eziphuthumayo zemishini ekhiqiza umusi.
Uma sithola ukuthi izinga lamanzi lemishini liphansi kunomkhawulo obonakalayo wengxenye engezansi yegeji yezinga lamanzi, lapho sandisa amanzi kanye nezinye izinyathelo, kodwa izinga lamanzi liyaqhubeka nokwehla, kanye nezinga lamanzi lemishini. idlula izinga eliphezulu elibonakalayo lamanzi, futhi izinga lamanzi alikwazi ukubonwa ngemva kokuphuma kwamanzi, ipompo yokuhlinzeka ngamanzi ihluleka ngokuphelele noma uhlelo lokuhlinzeka ngamanzi luhluleka. I-boiler ayikwazi ukuhlinzeka ngamanzi, wonke ama-gauge ezingeni lamanzi anephutha, izakhi zemishini zonakalisiwe, ezibeka engcupheni ukuphepha kwabasebenzisi kanye nemishini evuthayo, ukuwa kodonga lwesithando somlilo noma ukushiswa kwe-rack yemishini kusongela ukusebenza okujwayelekile kwemishini, nezinye izimo ezingavamile zibeka engozini ukusebenza okuvamile. we-steam generator.
Lapho uhlangabezana nalezi zimo, izinqubo zokuvala izimo eziphuthumayo kufanele zamukelwe ngesikhathi: landela ngokushesha umyalo wokuhlinzeka ngowoyela negesi, unciphise ukopha komoya, bese uvala ngokushesha i-valve ephumayo yesitimu esikhulu, uvule i-valve yokukhipha umoya, futhi unciphise umfutho we-steam.
Ngesikhathi sokusebenza okungenhla, ngokuvamile akudingekile ukuhlinzeka ngamanzi emishini. Ikakhulukazi esimweni sokuvalwa kwezimo eziphuthumayo ngenxa yokuntuleka kwamanzi noma amanzi agcwele, kuvinjelwe ngokuqinile ukuhlinzeka ngamanzi kubhayela ukuvimbela umusi omkhulu wenkanyezi ekuthwaleni amanzi futhi ubangele ukushintsha okungazelelwe kokushisa nokucindezela kubhayela noma amapayipi. kanye nokwanda. Izinyathelo zokuphepha zemisebenzi yokumisa isimo esiphuthumayo: Inhloso yemisebenzi yokumisa isimo esiphuthumayo ukuvimbela ukwanda okuqhubekayo kwengozi kanye nokunciphisa ukulahlekelwa kwezingozi nobungozi. Ngakho-ke, lapho wenza imisebenzi yokuvala ucingo oluphuthumayo, kufanele uhlale uzolile, uqale uthole imbangela, bese uthatha izinyathelo zembangela eqondile. Okungenhla kuyizinyathelo ezijwayelekile zokusebenza kuphela, futhi izimo ezikhethekile zizosingathwa ngokuya ngokwezimo eziphuthumayo.
