Pampu yamadzi ozizira:
Kachipangizo kamene kamayendetsa madzi kuti azizungulira m'madzi ozizira.Monga tikudziwira, mapeto a chipinda choyatsira mpweya (monga fani ya fani, mpweya wothandizira mpweya, ndi zina zotero) amafunikira madzi ozizira operekedwa ndi chiller, koma madzi ozizira sangayende mwachibadwa chifukwa cha kuletsa kukana, komwe kumafunika. mpope woyendetsa madzi ozizira kuti azizungulira kuti akwaniritse cholinga cha kutentha.
Pampu yamadzi ozizira:
Chida chomwe chimayendetsa madzi kuti azizungulira munjira yamadzi ozizira.Monga tikudziwira, madzi ozizira amachotsa kutentha mufiriji akalowa mu chiller, kenako amapita ku nsanja yozizirira kuti atulutse kutentha kumeneku.Pampu yamadzi ozizira imakhala ndi udindo woyendetsa madzi ozizira kuti ayendetse kuzungulira kotsekedwa pakati pa unit ndi nsanja yozizirira.Maonekedwe ake ndi ofanana ndi mpope wa madzi ozizira.
Pampu Yopangira Madzi:
Chida chowonjezera madzi chowongolera mpweya, chomwe chili ndi udindo wowongolera madzi ochepetsedwa mudongosolo.Maonekedwe ake ndi ofanana ndi mpope wamadzi wapamwamba.Mapampu omwe amagwiritsidwa ntchito kwambiri ndi pampu yopingasa ya centrifugal ndi pampu yoyima ya centrifugal, yomwe ingagwiritsidwe ntchito pamakina amadzi ozizira, makina oziziritsa komanso makina odzaza madzi.Pampu yopingasa centrifugal ingagwiritsidwe ntchito m'chipinda chachikulu, ndipo pampu yoyimirira ya centrifugal imatha kuganiziridwa ngati chipinda chaching'ono.

Monga momwe tawonera pa tebulo pamwambapa: pamene mpope wamadzi umayenda mofanana, kuthamanga kwa magazi kumachepa pang'ono;Pamene chiwerengero cha masiteshoni ofananira chikudutsa 3, kuchepetsedwa kumakhala koopsa kwambiri.
Zimapangidwa kuti:
1, kusankha mapampu angapo, kuganizira attenuation otaya, zambiri zowonjezera 5% ~ 10% malire.
2. Pampu yamadzi siyenera kukhala yoposa 3 seti mofanana, ndiko kuti, sayenera kukhala oposa 3 seti pamene firiji imasankhidwa.
3, ntchito zazikulu ndi sing'anga-kakulidwe ayenera kukhazikitsidwa motsatana ozizira ndi madzi otentha kuzungulira mapampu
Nthawi zambiri, kuchuluka kwa mapampu amadzi ozizira ndi mapampu amadzi ozizira kuyenera kufanana ndi kuchuluka kwa mafiriji, ndipo imodzi iyenera kugwiritsidwa ntchito ngati zosunga zobwezeretsera.Pampu yamadzi nthawi zambiri imasankhidwa molingana ndi mfundo yogwiritsira ntchito imodzi ndi zosunga zobwezeretsera kuti zitsimikizire kuti dongosololi lili ndi madzi odalirika.
Mapampu nameplate nthawi zambiri amakhala ndi magawo monga ovotera ndi mutu (onani pampu nameplate).Tikasankha mpope, choyamba tiyenera kudziwa kayendedwe ndi mutu wa mpope, ndiyeno kudziwa mpope lolingana ndi zofunika kukhazikitsa ndi malo malo.
(1) Njira yowerengera pampu yamadzi ozizira ndi mpope wamadzi ozizira:
L (m3/h) =Q(Kw)×(1.15~1.2)/(5℃×1.163)
Q- Kuzizira kwa wolandira, Kw;
L- Kuyenda kwa mpope wa madzi ozizira ozizira, m3/h.
(2) Mayendedwe a mpope woperekera:
Kuchuluka kwamadzi owonjezeranso ndi 1% ~ 2% ya kuchuluka kwamadzi ozungulira dongosolo.Komabe, posankha pampu yoperekera, kuyenda kwa mpope woperekera sikuyenera kungokumana ndi kuchuluka kwamadzi owonjezera pamadzi omwe ali pamwambapa, komanso lingalirani kuchuluka kwa madzi owonjezeranso pakachitika ngozi.Chifukwa chake, kuyenda kwa mpope woperekera nthawi zambiri sikuchepera 4 nthawi zamadzi owonjezeranso.
Kuchuluka kwa tanki yoperekera madzi kumatha kuganiziridwa molingana ndi madzi abwinobwino a 1 ~ 1.5h.
(3) Mapangidwe a mutu wapampu yamadzi ozizira:
Evaporator madzi kukana firiji wagawo: zambiri 5 ~ 7mH2O;(Onani chitsanzo cha malonda kuti mumve zambiri)
Mapeto zipangizo (mpweya akuchitira unit, zimakupiza koyilo, etc.) tebulo ozizira kapena evaporator madzi kukana: zambiri 5 ~ 7mH2O;(Chonde onani zitsanzo zazinthu zamtengo wapatali)
Kukana kwa backwater fyuluta, njira ziwiri zowongolera valavu, etc., zambiri 3 ~ 5mH2O;
Madzi olekanitsa, madzi otolera madzi kukana: kawirikawiri 3mH2O;
Kuzirala dongosolo madzi chitoliro pamodzi kukana ndi imfa m`deralo kukana: zambiri 7 ~ 10mH2O;
Mwachidule, mutu wa pampu ya madzi ozizira ndi 26 ~ 35mH2O, nthawi zambiri 32 ~ 36mH2O.
Zindikirani: mawerengedwe a mutu ayenera kutengera momwe zinthu ziliri mufiriji, sangathe kutengera zomwe zidachitikira!
(4) Mapangidwe a mutu wapampopi wozizira:
Condenser madzi kukana firiji unit: zambiri 5 ~ 7mH2O;(Chonde onani zitsanzo zazinthu zamtengo wapatali)
Utsi kuthamanga: zambiri 2 ~ 3mH2O;
Kusiyana kutalika pakati pa thireyi madzi ndi nozzle ya kuzirala nsanja (yotseguka yozizira nsanja): zambiri 2 ~ 3mH2O;
Kukana kwa backwater fyuluta, njira ziwiri zowongolera valavu, etc., zambiri 3 ~ 5mH2O;
Kuzirala dongosolo madzi chitoliro pamodzi kukana ndi imfa m`deralo kukana: zambiri 5 ~ 8mH2O;
Kufotokozera mwachidule, mutu wa mpope wozizira ndi 17 ~ 26mH2O, nthawi zambiri 21 ~ 25mH2O.
(5) mutu pampu chakudya:
Mutu ndi mutu wolemera wa mtunda pakati pa kupanikizika kosalekeza ndi malo apamwamba kwambiri + kukana kwa mapeto a kuyamwa ndi mapeto a mpope +3 ~ 5mH2O.
Mutha kulumikizana mwachindunji ngati mukufuna kugula kapena mgwirizano
