Q:Kodi kulephera kwa madzi a jenereta ya nthunzi ndi chiyani

A: Jenereta ya nthunzi nthawi zambiri imatenthetsa ndikutulutsa madzi mung'anjo kudzera pakuyaka kwamafuta kuti apereke moyo ndi kutenthetsa.Pazikhalidwe zodziwika bwino, kuyendayenda kwa madzi opingasa kumakhala kokhazikika, koma pamene kayendedwe ka kayendedwe kake kamakhala kosakhazikika kapena ntchitoyo ndi yosayenera, zolephera zina zimachitika nthawi zambiri.
Pansi pa nthunzi:
Pansi pazikhalidwe zogwirira ntchito za jenereta ya nthunzi, nthunzi siingakhalepo mu downcomer, apo ayi, madzi ayenera kuyenderera pansi, ndipo nthunzi iyenera kuyandama mmwamba, ndipo ziwirizo zimatsutsana wina ndi mzake, zomwe sizimangowonjezera kukana koyenda, komanso amachepetsa kufalikira kwa ma circulation , zinthu zikavuta kwambiri, kukana kwa mpweya kudzapangidwa, zomwe zidzapangitsa kuti madzi asamayendetsedwe, zomwe zimapangitsa kuti machubu a khoma lamadzi awonongeke chifukwa cha kusowa kwa madzi.Kuti athetse vutoli, chotsitsa cha jenereta cha nthunzi sichiyenera kutenthedwa ndi kutentha, ndipo chiyenera kugwirizanitsidwa ndi malo a madzi a ng'oma, momwe zingathere kugwirizana ndi pansi pa ng'oma, ndikuonetsetsa kuti kutalika pakati pa ng'oma. cholowera cha downcomer ndi mlingo wa madzi otsika ng'oma si otsika Kanayi m'mimba mwake wa downcomer.Pofuna kupewa nthunzi kuti isalowe mu chitoliro.

Lupu yakhazikika:
Pogwiritsa ntchito jenereta ya nthunzi, pamtunda womwewo wozungulira, pamene chubu iliyonse yokwera mofanana imatenthedwa mosagwirizana, kachulukidwe ka chisakanizo cha madzi a nthunzi mu chubu chomwe chimatenthedwa mofooka chiyenera kukhala chachikulu kuposa chisakanizo cha madzi a nthunzi. mu chubu chomwe chimatenthedwa kwambiri.Poganizira kuti madzi a m'mphepete mwa mtsinjewo ndi ochepa, kuthamanga kwa chitoliro chopanda mphamvu kumatha kutsika, ndipo kungakhale kopanda pake.Izi zimatchedwa cycle stagnation.Panthawiyi, nthunzi mu chitoliro chokwera sichingatengedwe nthawi., kutsogolera ku chitoliro khoma kutenthedwa chitoliro anaphulika ngozi.
Soda layering:
Pamene madzi ozizira khoma machubu a jenereta nthunzi amakonzedwa yopingasa kapena yopingasa, ndipo kuthamanga kwa madzi osakaniza nthunzi mu machubu si mkulu kwambiri, popeza nthunzi ndi yopepuka kwambiri kuposa madzi, nthunzi umayenda pamwamba pa madzi. machubu, ndipo madzi amayenda pansi pa machubu.Izi amatchedwa Soda-madzi stratification, chifukwa osauka matenthedwe madutsidwe nthunzi, pamwamba pa chitoliro mosavuta overheated ndi kuonongeka.Chifukwa chake, chitoliro chokwera kapena chotulutsira chamadzi osakaniza a soda sichingakonzedwe molunjika, ndipo kupendekera sikuyenera kukhala kosachepera 15 digiri.
Loopback:
Pamene Kutentha kwa chubu chilichonse chokwera mofanana kumakhala kosagwirizana kwambiri, kusakaniza kwa nthunzi-madzi mu chubu ndi kutentha kwakukulu kudzakhala ndi mphamvu yokweza mphamvu, kuthamanga kwake kudzakhala kwakukulu kwambiri ndipo mphamvu yokoka idzapangidwa, kuchititsa nthunzi. -Kusakaniza kwamadzi mu chubu ndi kutentha kofooka kuti muyende njira yosiyana ndi momwe mayendedwe amayendera, izi zimatchedwa kusinthasintha kwapang'onopang'ono.Ngati kukwera kothamanga kwa thovu kumakhala kofanana ndi kuthamanga kwamadzi otsika, kumapangitsa kuti thovu liziyenda bwino ndikupanga "kukana mpweya", zomwe zingayambitse kuphulika kwa chitoliro chotenthedwa mu gawo la chitoliro cha mpweya.
