Ngwenya amaphampu centrifugal: idivayisi iphinde ukusetshenziswa amaphampu ukuze imithombo nemithombo

Indlela ukukhetha imishini esifanele inhlangano ezimele yokutholakala kwamanzi? Kanye ilungiselelo umthombo amanzi eyanele (imithombo, imithombo) kumelwe unake okukhethekile indlela bokukhulisa ketshezi kuzo kwamanzi. Ukuze ukuxazulula le nkinga kakhulu ngokuvamile efakwe ngwenya amaphampu centrifugal.

phetho

yokutholakala kwamanzi Independent inezigaba eziningana: umthombo ahlanzekile izinhlelo amanzi piping nokucindezelwa ukudala izindlela kokuthutha uketshezi. design yabo efanele futhi nihlanganyele ayisiqinisekiso lusebenze kahle.

Uzotshala imishini the main okuyingxenye, okuyinto ukwenza imisebenzi elandelayo:

• Ukuphakamisa amanzi okuphuza okuvela komunye umthombo komhlaba ukusatshalaliswa uhlelo lwayo.
• Ukuqinisekisa ingcindezi oyifunayo nevolumu inkomba.
• ukusebenza ongenaziphazamiso (ngokuhambisana nemibandela yokusebenza).
• kalula Maximum lokulawula inqubo ezishintshayo.

Omunye izixazululo engcono ezihlangabezana mibandela engenhla kuyoba ukufakwa amaphampu centrifugal. Kanye nokwakhiwa elula futhi enokwethenjelwa, banayo izakhiwo ezinhle ukusebenza. endaweni yabo eyinhloko isicelo - ephakamisa amanzi kusukela kumbiwa imithombo nemithombo. Kuye ukujula kushintshwe ngwenya amaphampu centrifugal of ezikhundleni ezehlukene. Ukuze kumbiwa imithombo leli nani ukufinyelela 50 m. G. Wells ezimweni eziningi ube 7 m ukujula.

Umgomo we operation

Isisekelo Ukukhetha efanele futhi msebenzi circuit ukusebenza okuyinto eyenza ngwenya amaphampu centrifugal kwamanye amadivayisi we injongo efanayo. design yabo oluhambisana nemibandela yokusebenza - ngokuba naphakathi ketshezi, izindlu kumele kutsi babe sesimeni ukugqwala. Njengoba njengoba amandla iyunithi isebenzisa i motor ngogesi, ke kuba isibopho ukuqedela ungangenisi amanzi ukuvimbela iloli nokuhluleka. Cabangela ama-apharathasi ngwenya futha centrifugal. futha ejwayelekile siqukethe izinto ezilandelayo:

1. Motor - uphawu ekupheleni futha, lapho amandla iyunithi ifakiwe. Nge ukujikeleza amandla kushaft engeyokuqala elilandelayo isiyakhashelwa.
2. Ikamelo vane - itholakala ezansi zedivayisi. It yenzelwe ukwakha ingcindezi, ngenxa lapho lamanzi linyuka.
3. Komsele - iyunithi zokuthutha ezihamba ketshezi kuze kube seqophelweni umthengi - uhlelo amanzi ekhaya noma ayakhala.

I futha wenziwe izinto lungekho ukugqwala - eliphezulu insimbi engagqwali noma polymers. I ephansi izindlu ingxenye ethola ukuvuleka ahlelwe okuyinto yenza umsebenzi lemifanekiso. izinhlayiya zezinsimbi ezinkulu ungafaki futha. Phakathi ukujikeleza izindwani ngaphansi isenzo amandla centrifugal kwenzeka yokuhamba amanzi uquqaba ethola idivayisi egumbini. Ngesikhathi esifanayo bekhonza njengoba kokupholisayo injini, ekuvimbeleni ke okweqile. Okwephoyinti ngesikhathi esifanele (stop) control futha iyunithi exhunywe iflothi ezingeni izinzwa amanzi. Ngaphandle kwabo, uhlelo kungenziwa exhunywe yangaphandle control izakhi - inkinobho ingcindezi emanzini noma ngqo ekhaya switch (off).

izinhlobo

Kuye Ukucaciswa, ngwenya amaphampu centrifugal kungenzeka design ukuhluka. Uma ukhetha imodeli elilungile kufanele bacabangele ukwakheka kanye degree of ukungcola kwamanzi, kanye nokujula yayo. Isici lwakamuva bayoba kungithinte amandla kwe-futha.

Umklamo onobuhle yasekhaya lilula: injini ne bendiza ngesikhatsi operation edonsa ingcindezi amanzi anele. Basuke izimpawu zibe lula, ukuthembeka, babe Ubukhulu ezincane. Kodwa uma emkhathizwe amanzi okuphuza kuyinto nesenzakalo ayikajuli - ukufakwa izinhlobo eyinkimbinkimbi yokwakha.

Ukuze wandise lokhu ipharamitha centrifugal amaphampu ngwenya ngoba amanzi ifakwe injini qinile a isondo lokugijimisa indiphi elenzelwe into esindayo mpo nge impellers amaningi. Ngenxa yalokhu bewakha ethuthukisiwe ingcindezi amanzi ukuyiphakamisa kwamanzi.

ezakhiwe efanayo futhi esetshenziselwa uzotshala uwoyela. Banezinhliziyo ukusebenza okuhle, futhi okubaluleke - okuthembekile.

izici

Zikagesi Standard ngwenya futha centrifugal ikhethwa esekelwe ukusebenza kwayo. Kufanele sinake isilinganiso amandla. Kuyinto lunqume lapho ekhetha hlobo locingo. Ngaphezu kwalokho, isidingo ukwazi imingcele zedivayisi yilezi:

• Umthamo uketshezi akhishwa - l / imiz.
• Ukuphakama ikholomu amanzi. Icacisa womthombo (kahle) kanye nobude enezingqimba iphayiphi ukujula esiphezulu.
• imishini engeziwe - ezingeni amanzi izinzwa kanye eziphuthumayo ukuvala shaqa.

Ezezindlu namadivayisi amaningi eyenziwe ngensimbi engagqwali. Imodeli ongaphakeme-amandla, eyenzelwe encane alondoloze nemithombo yamanzi ukuphakama, kungashiwo esakhiwe ngezinto polymeric.

izimo zokusebenza

Modern ngwenya amaphampu centrifugal kufanele zisebenze ezimweni zazo ngokucacile elicacisiwe imiyalelo. Lokhu kuzoncika hhayi kuphela izinga kudivayisi, kodwa futhi ukuqina yayo. Uhlelo oluyisisekelo oluthi izici nokusebenza zihlanganisa ukwakheka kanye lokushisa kwamanzi, degree of ukungcoliswa yayo. Kufanele uqaphele kakhulu kuqiniswa supply voltage.

Ngokuvamile ngwenya centrifugal amaphampu ukuze imithombo setha eziqiwini ezizimele, lapho wamanje agxume - Kuyaziwa. Motor ayinakho ngesivikelo esiphumelelayo ekuvimbeleni yokwanda kwama ezinjalo. Ngakho-ke, kutuswa ukuxhuma idivayisi ngokusebenzisa kuqiniswa iyunithi.

ukufakwa

Imithetho eyisisekelo yokumiswa zichazwe ngokuningiliziwe ku bhukwana imfundo. Uma udinga ukufaka centrifugal futha ngwenya i-kahle, kufanele unake isimiso kokulilungisa. Esikhathini izindlu futha eyilungu ekhethekile nokubopha. Kuyadingeka ukufakwa ikhebula ngwenya.

Indaba ukwakhiwa kumele bahlangabezane nalezi zidingo ezilandelayo:

• Doesnt adle.
• Umthwalo ngesikhathi sekhefu kumele singeqi isisindo kudivayisi okungenani izikhathi 5.

Akuvunyelwe ukuba asishiye kudivayisi kuphela nge ikhebula amandla. Umthwalo oyinhloko kufanele iwe ku inhlangano ikhebula. It unamathele kwamanzi, noma ukuba ugongolo isiphambano entanyeni kahle noma izindonga zangaphandle ayisivikelo kahle.

isevisi

Leli bhukwana libonisa isikhathi elilinganisiwe umsebenzi yesondlo. Bahlanganyela aqukethe e kokuhlola yobunzima leli cala, esikhundleni lwezimpawu iraba ku induku motor futhi ehlanza oxhumana uxhumano. Esimweni iphutha elingalindelekile kufanele sibhekiswe abamele umenzi noma ezikhethekile yokulungisa.

Kuyadingeka ukuba sicabangele ukuthi centrifugal amaphampu ngwenya kungenziwa ngaphezu kwalokho ifakwe izihlungi pretreatment. Basuke efakwe itheku ipayipi iyunithi futhi esikhundleni uma engcolile.

Amathiphu Ukukhetha

Ngaphambi kokuba uthenge odinga ukukwazi ngokucacile izimo yokusebenza centrifugal futha ngwenya i-kahle izosebenza ngaphansi okuyinto ngokufanele. Kunconywa ukuba banamathele iziqondiso ezilandelayo:

1. amanzi ukusetshenziswa. Amanzi ukulethwa rate kufanele luhambisane nemithetho zokuhlala.
2. Ukuphakama ikholomu amanzi. Uma izibalo yakhe acabangele womthombo (kahle) hhayi kuphela ukujula, kodwa izigaba ovundlile. Kubo, Coefficient 0.1 isetshenziswa kunciphisa. Uma womthombo ukujula kuyinto 7 m, kanye umugqa ovundlile has a ubude 12 m, ukuphakama ubuncane kukholamu amanzi kwe-futha kufanele kube: 12 x 7 + 0.1 = 8.2 m.
3. EBukhoneni ezingeni amanzi izinzwa e kit.
4. Iwaranti on imishini, ibanga sesevisi ye umenzi.

Ngenxa yalezi izibalo, kungenzeka ukuba ukhethe imodeli kahle esiteshini ukudonsa, ezizohlinzeka lemali efanele yamanzi. Ngaphezu kwalokho, zikwazi ukwenza umsebenzi amanzi zewayini amanzi ezindlini. Into esemqoka - acabangele indlela yokwakheka uketshezi imikhawulo kuvunyelwe ukungcoliswa model ethize futha.

Ngenxa yalokhu bewakha ethuthukisiwe ingcindezi amanzi ukuyiphakamisa kwamanzi.
