Indlela ukukhetha nempompo ngenxa kakuhle: ukusebenza kunye noxinzelelo

Inqanaba yanamhlanje inkqubela ukuba lali, iilali abanini esemaphandleni kunye nezindlu amalungiselelo elula kakuhle inkqubo yonikezelo lwamanzi kwindlu phezu isiseko iqula okanye umthombo. Akukho mfuneko, hayi kuphela emele, kodwa kwamandla zizonke, ngokuqhelekileyo zibekwe eliphezulu. Ukwazi ukuba ukhethe njani pump ngenxa kakuhle, ibe ndawonye kwisikhululo sokumpompa amanzi kunye zokusebenzisa ngokupheleleyo inkqubo yokufumana amanzi kumthombo angaphantsi komhlaba. Ngomhla lokukhetha lasekunene kwaye kuya kuxoxwa ngazo kweli nqaku.

Isisekelo yokukhetha

Ngaphambi sesihloko evenkileni ukuthenga, kufuneka wenze isigqibo malunga amanqaku athile aphambili benzela yokukhetha. Nazi ke:

- Umgama ukusuka wequla etephini. Ukusukela ukuba imitha nganye akhawunti umbhobho ubude ilahleko ethile pressure, akunakwenzeka ukuba ngoyaba eli xabiso;

- umthamo wamanzi ekhoyo. Kufuneka kwakhona limisele debit, ie ukufunda ngamava, kuba yintoni ixesha ixesha kukho ukuzaliswa kakuhle nasemaquleni. Ngokucacileyo, yenza akukho ingqiqo ukufumana pump ngokugqithiseleyo kakuhle kunye umthamo amancinane amanzi kunye uviko minor - yonke into kufuneka elungeleleneyo;

- ubunzulu ukusuka emhlabeni ukuya etafileni emanzini;

- volume eyiyona ziphele. Kufuneka mayingagqithi debhithi.

Zonke ezi data yanele, ukuba kuyimfuneko, umcebisi sinokunceda ukufumanisa ezikhethiweyo ukuguqulwa eyimfuneko isixhobo sokumpompa amanzi.

Indlela ukukhetha nempompo for kakuhle

Zonke izisombululo ezikhoyo lokubonelela amanzi avela kwimithombo angaphantsi lungohlulwa lube iintlobo ezimbini - ngwenya kunye komhlaba. Ulwakhiwo yokuqala ibeka isixhobo kwikholam emanzini, lanqunyanyiswa intambo okhethekileyo. Le yokugqibela, yona, akukho hermetic yaye ukuqhagamshelana ukufuma engathi motor nokuba yonakele. Ukongeza, umgaqo yokusebenza yahlukile, kunye nezakhono yesixhobo ngasinye. Umzekelo, indlu iimpompo ngwenya inokuba ukungcangcazela (uguqulelo ininzi), isixhobo sokubhola (uyilo ukuhlehla) kunye centrifugal. Umphezulu singakwazi ukuqhayisa intabalala. Ngoko ke, sithetha ngayo ukukhetha indlela nempompo kuba kakuhle, siya kuthetha malunga imifuziselo ngwenya.

Zonke ezi iimpompo kufuneka eziphambili ezimbini kuphela parameters eziphembelela nokusebenza le nkqubo - ukuba uxinzelelo wesiqhelo kunye nokusebenza. Amaxabiso Incopho umdla kuphela ngokwembono ezithile "sokuphepha" - intsebenziswano eqhubekayo ayikhuthazwa kula iindlela. Ukufunda umbuzo ukuba ukhethe njani pump ngenxa kakuhle, kufuneka sinikele ingqalelo into yokuba iimpawu ezimbini ikhankanywe apha ngentla ezichaphazela ngokuphawulekayo ixabiso lokugqibela ifowuni.

Ngoko ke, kwezinye iimeko iyavakala ukutshintsha wesekethe yonikezelo (umzekelo, ukuba balungiselele kakuhle ngenxa accumulator), hayi overpaying ukuba nempompo enamandla ngakumbi.

Ngwenya iimpompo for zamaqula. Ukukhethwa parameters

Ukucinga ukuba umgama "umgangatho - mirror amanzi" yi-16 m, kanti ukuya kwindawo draw (ethe tye) - A impompo ngwenya ethile abstract, emelwe evenkileni, unako ukunika 2500 l ngeyure kwi yintloko kweemitha 60 20 m.. ukulahleka Pressure bakholelwa 1 emoyeni elivumelana nokonyuka ukuphakama-10 m, kanti ke umgca oxwesileyo - amaxesha 10 ngaphantsi.

Kuba kulo mzekelo, kunye m yayo intloko 60 ngamashishini yalo mbhobho uya 60-16-2 = 42 m, okanye 4.2 ATM. Ngenxa ukuguquka kunye amathuba, ekugqibeleni sifumana 4 ATM. Ekubeni ummiselo phakathi kwe-3 no-4 umoya, le modeli sifanelekile kakuhle.

Ubungakanani bamanzi anikezelweyo kungaba ibalwe kusetyenziswa ishedyuli ehlonyelwe sheet data. Emisa ilahleko (16 + 2 = 18 m) iyafuneka kweli nqanaba ukuze ukrwele umgca phezu igrafu kwigophe nencopho kwikona - nkqo kwezinye esqwini. Fumana ukusebenza.
