Indlela yokukhetha eyona Mpompo ifanelekileyo

Impompo yonikezelo lwamanzi:

Isixhobo sokuzalisa amanzi somoya womoya, onoxanduva lokunyanga amanzi athambekele kwisixokelelwano.Ubume bufana nempompo yamanzi ephezulu.Iimpompo ezisetyenziswa ngokuqhelekileyo yimpompo ye-centrifugal ethe tye kunye nempompo ye-centrifugal ethe nkqo, enokusetyenziswa kwinkqubo yamanzi epholileyo, inkqubo yamanzi okupholisa kunye nenkqubo yokuzaliswa kwakhona kwamanzi.Impompo ye-centrifugal ethe tyaba ingasetyenziselwa indawo enkulu yegumbi, kwaye impompo ye-centrifugal ethe nkqo inokuqwalaselwa kwindawo encinci yegumbi.

 

Intshayelelo kwimodeli yempompo yamanzi, umzekelo, 250RK480-30-W2

250: i-inlet ububanzi 250 (mm);

I-RK: impompo ejikelezayo yokufudumeza kunye nomoya womoya;

I-480: indawo yokuhamba yoyilo 480m3 / h;

30: inqaku lentloko yoyilo 30m;

I-W2: Uhlobo lokuxhoma impompo.

 

Ukusebenza ngaxeshanye kweempompo zamanzi:

Inani leempompo	ukuhamba	Ixabiso elongeziweyo lokuhamba	Ukunciphisa ukuhamba xa kuthelekiswa nokusebenza kwempompo enye
1	100	/
2	190	90	5%
3	251	61	16%
4	284	33	29%
5	300	16	40%

Njengoko kunokubonwa kwitheyibhile engentla: xa impompo yamanzi ihamba ngokufanayo, izinga lokuhamba liyancipha ngandlela-thile;Xa inani lezikhululo ezihambelanayo lidlula i-3, ukuthotywa kuba nzima kakhulu.

 

Kucetyiswa ukuba:

I-1, ukukhethwa kweempompo ezininzi, ukuqwalasela ukuthotywa kokuhamba, ngokubanzi ukongeza i-5% ~ 10% umda.

2. Umpompo wamanzi akufanele ube ngaphezu kweesethi ezi-3 ngokuhambelanayo, oko kukuthi, akufanele kube ngaphezu kweesethi ze-3 xa umgcini wefriji ekhethiweyo.

3, iiprojekthi ezinkulu neziphakathi kufuneka zisekwe ngokulandelelanayo iimpompo ezijikelezayo zamanzi abandayo nashushu.

 

Ngokuqhelekileyo, inani leempompo zamanzi ezipholileyo kunye neepompo zamanzi zokupholisa kufuneka zihambelane nenani lemikhosi yefriji, kwaye enye kufuneka isetyenziswe njenge-backup.Umpompo wamanzi ukhethwa ngokubanzi ngokuhambelana nomgaqo wokusetyenziswa kunye kunye ne-backup enye ukuqinisekisa ukunikezelwa kwamanzi okuthembekileyo kwenkqubo.

Iipleyiti zamagama epompo ziphawulwa ngokubanzi ngeeparamitha ezinjengokuqukuqela okulinganisiweyo kunye nentloko (jonga i-nameplate yempompo).Xa sikhetha umpompo, kufuneka siqale sinqume ukuhamba kunye nentloko yempompo, kwaye emva koko sinqume ipompo ehambelanayo ngokweemfuno zofakelo kunye nemeko yesayithi.

 

(1) Ifomula yokubala ukuhamba kwempompo yamanzi abandayo kunye nempompo yamanzi okupholisa:

L (m3/h) =Q(Kw)×(1.15~1.2)/(5℃×1.163)

Q- Ukupholisa umthamo wenginginya, Kw;

L- Ukuhamba kwempompo yamanzi okupholisa abandayo, m3/h.

 

(2) Ukuhamba kwempompo yonikezelo:

Umthamo wamanzi ohlaziyiweyo oqhelekileyo yi-1% ~ 2% yomthamo wamanzi ajikelezayo kwisixokelelwano.Nangona kunjalo, xa ukhetha ipompo yokubonelela, ukuhamba kwempompo yokubonelela akufanele kuhlangane kuphela nomthamo wamanzi ohlaziyiweyo oqhelekileyo wenkqubo yamanzi engentla, kodwa kwakhona kuqwalaselwe ukunyuka komthamo wamanzi wokutshaja xa kwenzeka ingozi.Ngoko ke, ukuhamba kwempompo yokubonelela ngokuqhelekileyo kungabi ngaphantsi kwamaxesha ama-4 omthamo wamanzi ohlaziyiweyo oqhelekileyo.

Umthamo osebenzayo wetanki yonikezelo lwamanzi unokuqwalaselwa ngokonikezelo lwamanzi oluqhelekileyo lwe-1 ~ 1.5h.

 

(3) Ukwenziwa kwentloko yempompo yamanzi abandayo:

Ukumelana namanzi e-Evaporator yeyunithi yefriji: ngokubanzi 5 ~ 7mH2O;(Jonga isampuli yemveliso ngeenkcukacha)

Izixhobo zokuphelisa (iyunithi yokuphatha umoya, i-coil ye-fan, njl.) i-cooler yetafile okanye i-evaporator ukumelana kwamanzi: ngokubanzi i-5 ~ 7mH2O;(Nceda ubhekisele kwisampulu yemveliso yamaxabiso athile)

 

Ukumelana nesihluzo samanzi angasemva, ivalve yokulawula iindlela ezimbini, njl., ngokuqhelekileyo yi-3 ~ 5mH2O;

Isahluli samanzi, ukunganyangeki kwamanzi komqokeleli wamanzi: ngokubanzi i-3mH2O;

Umbhobho wamanzi wenkqubo yokupholisa ecaleni kokuchasana kunye nelahleko yokumelana nendawo: ngokubanzi 7 ~ 10mH2O;

Ukushwankathela, intloko yempompo yamanzi epholileyo yi-26~35mH2O, ngokubanzi 32~36mH2O.

Qaphela: ukubala kwentloko kufuneka kusekelwe kwimeko ethile yenkqubo yefriji, ayikwazi ukukopisha ixabiso lamava!

 

(4) Ukwenziwa kwentloko yempompo yokupholisa:

Ukuchaswa kwamanzi kweCondenser yeyunithi yefriji: ngokubanzi 5 ~ 7mH2O;(Nceda ubhekisele kwisampulu yemveliso yamaxabiso athile)

Uxinzelelo lokutshiza: ngokubanzi 2 ~ 3mH2O;

Umahluko wokuphakama phakathi kwetreyi yamanzi kunye nomlomo wenqaba yokupholisa (inqaba yokupholisa evulekileyo): ngokubanzi 2 ~ 3mH2O;

 

Ukumelana nesihluzo samanzi angasemva, ivalve yokulawula iindlela ezimbini, njl., ngokuqhelekileyo yi-3 ~ 5mH2O;

Umbhobho wamanzi wenkqubo yokupholisa ecaleni kokuchasana kunye nelahleko yokuchasana kwendawo: ngokubanzi 5 ~ 8mH2O;

Ukushwankathela, intloko yempompo yokupholisa yi-17 ~ 26mH2O, ngokubanzi 21 ~ 25mH2O.

 

(5) intloko yempompo yokutya:

Intloko yintloko ecebileyo yomgama phakathi kwendawo yoxinzelelo oluqhubekayo kunye neyona ndawo iphakamileyo + ukuchaswa kwesiphelo sokufunxa kunye nokuphela kokuphuma kwempompo +3 ~ 5mH2O.
