Ukufakwa kwepompo yokuhambisa ukushisa. Ukukhethwa kwepump, ukufakwa, imiyalelo

Ukusabalalisa ohlelweni lokushisa kungenziwa kokubili ngokuphoqeleka nangokwemvelo. Ukwakha ukunyanzeliswa okuphoqelelwe, faka imishini yokudonsa. Ukufakwa kwepompo yokuhambisa ukushisa kuyoqinisekisa ukuthi izinga lokushisa elifanako kanye nokushisa kwesikhala. Ukukhethwa kwale divayisi kufanele kulandelwe ngokuziphendulela, ngoba ipompo ekhethiwe ngokungakhethi iyodala ukuhambisa okunamandla kakhulu noma okunamandla kakhulu kwe-coolant ohlelweni. Lokhu kamuva kuhlanganisa ukushisa okungalingani kwekamelo.

Umklamo wokusebenza nokusebenza

Ipompo yokujikeleza yokushisa (intengo - kusukela ku-3 500 kuya ku-15 000 ruble) iyisici esiyinhloko sesistimu ekuqhunywe ngokuphoqeleka kwe-coolant. Kulesi simo, akudingekile ukufaka amapayipi amakhulu bese ufaka i-boiler endaweni ephansi kunazo zonke. Ngaphezu kwalokho, isikhathi sokushisa amadivaysi okushisa sifinyeleleka ngokucacile, okwenza sikwazi ukwandisa izinga lokushisa emoyeni ekamelweni esikhathini esifushane. Izici eziyinhloko zemishini yokupompa yikhanda kanye nokukhiqiza.

Inhloko yepompo kumele inqobe ukumelana kwamanzi kagesi. Njengoba kunesimo esincane sokumelana namagesi kanye nenhloko encane yemishini, kubalulekile ukufaka ipompo yokuhambisa ukushisa enezinye izici.

Ukuthembeka nokusebenza okuqhubekayo kwamapayipi okudonsa ngokuyinhloko kuxhomeke ekubaleni kahle kwemingcele yokusebenza, okuhlelwe kuyo ukushisa izakhiwo, kanye nendlela yokufakwa kahle ngayo. Isibonelo, ukujikeleza amaphampu Wilo noma GrundFos efakwe ohlelweni lokushisa, okuyinto imvelo evaliwe, bayakwazi ukusebenza ngaphansi kwengcindezi ephezulu ezindaweni ezimbalwa. Ngakho-ke, ukuze ugcwalise uhlelo, imishini ifakwe ngcindezi yokupompa, ehlangene nokushisa noma kumbhobho wamanzi onomfutho omkhulu. Khona-ke ukuhlolwa kwenziwa.

Izinhlobo

Kunezinhlobo ezimbili eziyinhloko zamadivayisi:

• Uhlobo omile.
• Uhlobo "olumanzi".

Ngalunye lwalezi zinhlobo zezici zokungaphumeleli nezinzuzo zabo, cabangisisa ngokuningiliziwe.

Izinzuzo 'zohlobo olomile'

• Ngesikhathi sokusebenza, imishini enjalo ayisebenzisani ne-pumped medium. Lokhu kunikeza impilo yesikhathi eside.
• Izakhiwo zenziwe ngokucophelela futhi zicutshungulwa. Ngenxa yalokho, ukufakwa kwepompo yokuhambisa ukushisa uhlobo olomile luzovimbela ukuvuza kwesimiso esivela ohlelweni.
• Ukusebenza kahle cishe ngu-80%.
• Izigxobo zokumboza azidingi ukufakwa endaweni engakapheli iminyaka engu-2.5-3, ngokungafani nebhokisi lokugxilisa, elidinga ukubuyekezwa ngaphambi kokuqala kwenkathi ngayinye yokushisa.
• Izinsiza zalolu hlobo zingakhululwa kokubili ngokuqondile nangokuzungezile. Noma kunjalo, isikhundla sakhe asithinti izinga lomsebenzi nganoma iyiphi indlela.

Izinkinga zohlobo olumile

• Iningi lomsindo lenziwa ngesikhathi sokusebenza kwemishini. Ngenxa yalesi sizathu, ukufakwa kwepompo yokuhambisa ukushisa "okumile" kufanele kuhlinzekwe ekamelweni elihlukile.
• Lezi zinyunithi zizwela kakhulu kwizinga le-coolant. Umsebenzi omude futhi ophezulu emanzini anethweko akufanele kube khona ukungcola nokungcola.
• O-izindandatho zidinga ukugcoba ngezikhathi ezithile.

Izinzuzo zohlobo "olumanzi"

• Ukugcinwa kalula nokufakwa.
• Impilo yesikhathi eside.
• Izinga lomsindo ophansi.
• Izindleko eziphansi kakhulu zezingxenye ezisekelwe kanye neyunithi ngokwazo.
• Uma ukusebenzisa imishini yokupaka akudingi i-lubricant, okuyivimbela ekukhenizeni. Lo msebenzi uqhutshwa yi-coolant, epholisa, futhi iphinde igcobe i-pump shaft.

Izinkinga zohlobo "olumanzi"

• Ukusebenza kahle, cishe 30%.
• Ukufakwa kwamapompu okushisa okuhambayo okuluhlobo oluthile olwenziwe "wet" kufanele kwenziwe kuphela endaweni enezingqimba.
• Kungenzeka ukuvuza okuvela kuhlelo lokushisa ngokusebenzisa ukuvuza kwemishini yokudonsa.

Ipompo yokujikeleza yokushisa: indlela ongayikhetha ngayo

Uma ukhetha imishini yokudonsa, lezi zici ezilandelayo kufanele zibhekwe: ukukhiqiza, ukugeleza kanye nenhloko. Njengomthetho, baboniswa epasipoti.

Inhloko

Ukuze ukhethe kahle ipompo yokuhambisa ukushisa ngekhanda elidingekile, kubalulekile ukubala ukumelana kwamanzi kagesi . Kuxhomeke ubude nobubanzi bamapayipi, kanye nenani lezimangalo zendawo (i-constriction, ama-angles of rotation, njll). Inhloko yemishini yokudonsa kumele ikhethwe ngendlela yokuthi inqobe ukumelana kwayo yonke uhlelo.

Ipompo ekhethiwe kahle iyisiqinisekiso sokusheshisa okukhulu kokujikeleza, kanye nokugeleza kuzo zonke amakamelo okupholisa.

Ukusetshenziswa

Ukukhethwa kwempompo yokuhambisa ukushisa, ngokusekelwe kokugeleza komthwali wokushisa, kufanele kube nokuqondiswa komthwalo wesistimu. Umthwalo ubalwa ngezindlela eziningana: ngokusho kwama-radiator afakwe ngaphakathi noma ivolumu yangaphandle yesakhiwo. Ukugeleza kungabalwa ngefomula, lapho ngaphezu komthwalo wokushisa, kuyadingeka ukwazi imodi yokusebenza yebhayili.

Amandla wemishini atholakala ngokulandela imibhalo yokulawula. Ngokusho kwamazinga aseNtshonalanga, indawo eyodwa ye-1 m ² yendawo kufanele ibe ngu-100 W. Kodwa-ke, ngokugxila kwezimo zezulu zendawo, imishini enekhono lokungenani okungu-120 W kufanele ifakwe ku-1 m ² .

Ezinye izinto

Amandla emishini yokudonsa ngokuqondile ihlobene ngqo nobubanzi bamapayipi. Abanye bakholelwa ukuthi ukuphakama kwamapayipi amakhulu, ukushisa okungeziwe kuyokungena ekamelweni. Kubalulekile ukucabangela ukuthi inani elikhulu lokudlulisa izinga lokushisa lihamba ngezindiza ezinkulu, ngakho-ke, ukuhambisa amaphampu kuyadingeka ukuthi kusetshenziswe ukushisa, izici zazo ezihlaba umxhwele ngamandla abo. Lokhu kuzoqinisekisa ukuhamba kwezinga eliphezulu.

Indawo yesikhungo sepompo sinomthelela omkhulu ekusebenziseni amandla kanye nokusebenza kwayo. Ipompo efakwe ekamelweni elibandayo njalo lisebenza ngendlela engavamile futhi libi nakakhulu, ngokungafani nelinye elifakwe esakhiweni esinokushisa.

Umthamo wemishini nayo ixhomeke esikhathini esilindelekile sokusebenza. Uma, isibonelo, isikhathi esiningi ukusakazwa kuhlelo lokushisa kungokwemvelo, futhi ipompo iqala kuphela ukushisa okusheshayo ekamelweni noma ukulungisa ikhanda, khona-ke amandla amaningi ngeke adingeke.

Ukubalwa kokugeleza

Ukuhambisa amaphampu ukushisa izindlu zangasese kunezici eziningi ezicacisa amandla abo okusebenza. Ukusetshenziswa nokucindezelwa yizikhombisi eziyinhloko zokupompa amayunithi. Lezi ziminganiso zibonakala kwisitifiketi sokusebenza. I-pump unit unit kufanele ibalwe ngokusebenzisa ifomula elandelayo:

Q = N / (t ₂ -t ₁ ), lapho:

• N amandla omthombo wokushisa (ubheyili, ikholomu yegesi).
• I-T ₂ yizinga lokushisa lomthwali wokushisa emgqeni wokunikezela nokuphuma emthonjeni wokushisa. Cishe wonke ama-boilers asethwe kwimodi yokusebenza ka 90-95 ° C.
• I-T ₁ ukushisa kwe-coolant emgqeni wokubuyisela, njengombuso, izinga lokushisa layo lingu-60-70 ° C.

Le pharamitha ikuvumela ukuthi unqume ukuthi i-pump yokuhambisa ifanele yini ukushisa, indlela yokuyikhetha ngokufanele ngeke ibe yinkinga enzima kuwe.

Abakhiqizi

Njengamanje, abakhiqizi abakhulu kakhulu bezinsimbi zokupompa yizinkampani zaseYurophu, njengoba zikhonjiswe ngezinto eziphezulu zekhwalithi kanye nomhlangano, kanye nomnotho.

Emakethe yezinto zokushisa, amaphampu aseJalimane ajikeleza i-Wilo asetshenziswe iminyaka eminingana kakade. Ngalesi sikhathi bazibonakalisa njengemishini ephakeme futhi ephezulu. Ukukhethwa kwabathengi kunikezela ngezindlela ezihlukahlukene zokuphambanisa amayunithi anezici eziningi ezihlukahlukene. Ukuze ufake ohlelweni lokushisa, izinga lokushisa eliphakeme kakhulu (intengo - kusuka kuma-ruble angu-12 000) i-Wilo-Stratos ECO. Umfutho owenziwe yilo yunithi yikholomu yamanzi angu-5, amandla angu 2.5m ³ / h, kanti ukusetshenziswa kwamandla kungu-59 W. kuphela. Idivayisi enjalo ingasebenzisa kokubili kwimodi yokuzenzakalelayo neyomuntu. Kungenzeka futhi ukulungisa isivinini sejinini namandla.

Ukuphakama

Ngaphambi kokufaka amaphampu okufudumalayo okufudumalayo, kufanele uqaphele ukuthi akukhathaleki ukuthi yiluphi ulwazi oluzokwenza uhlelo. Izinto zokusebenza zingcono ukuxhuma ngqo kumpayipi, kodwa emgqeni we-bypass.

Emgqeni omkhulu wokushisa, ohlangothini, elinye iphayiphi ngesimo sencwadi ebanzi "P" idayiswa noma ifakwe, ngepom efakwe phakathi. Ezimbili zombili ziyizixhobo zokukhiya ezifakiwe, ezidingekayo ngezinhloso ezilandelayo:

• Ukweqa enye ye-cranes kuzobuyisela ukusakazwa kwemvelo kwe-coolant ohlelweni.
• Ukuqoqa izigubhu zombili zomgwaqo kuzosiza ukulungisa noma ukufaka esikhundleni sepompo yokuhambisa ukushisa (ukubuyekezwa kochwepheshe kuqinisekisa lokhu) ngaphandle kokukhipha i-coolant.

Ngesikhathi sokufakwa, ukunakwa kufanele kukhokhwe ekuqondeni kokugeleza kwepholile. Njengomthetho, kuboniswa umcibisholo esimweni sedivayisi.

Uma uxhuma ohlelweni lwegesi ohlelweni lokushisa lokushushumbisa kwemvelo, kutuswa ukuba usebenzise i-fuse othomathikhi nefulegi. Kuzosebenza ngesikhathi esisodwa njengenguquko kanye nokufiphaza. I-fuse okuzenzakalelayo kufanele ifakwe ebangeni elingenani 0.5 m kusuka kuma-heaters.

Ukuze uxhume ipompo eyengeziwe ohlelweni lokunyathelisa ngokuphoqeleka, kubalulekile ukucabangela iqiniso lokuthi omunye usuvele efakwe futhi uqala lapho uhambo oludlulayo lokudlulisela. Ukuthi izimoto zokuhambisa zifudumeza ukushisa izindlu zangasese zisebenza ngokuvumelanisa, i-unit eyengeziwe kufanele ixhunywe kudivayisi esemqoka noma ukulayishwa okushisayo ngokusebenzisa uxhumano olufanayo.

Ukushisa amasistimu anezibhamu zikagesi, imishini yepompo ingaxhunyaniswa ngqo ebhokisini. Kulesi simo, iyunithi yokujikeleza iyosebenza kuphela ngesikhathi sokushisa okupholile.
