Indlela ukukhetha futha ngokuba kahle: ukusebenza ingcindezi

Izinga yesimanje kwenchubekelembili bavunyelwe bakule ndawo, abanikazi lizwe cottage nasemizaneni Cottages ukuhlela elula futhi ephumelelayo amanzi supply system yendlu ngesisekelo kahle noma Borehole. Asikho isidingo, hhayi kuphela e amabhakede, kodwa futhi amakhono jikelele, ngokuvamile ibekwe egunjini eliphezulu ophahleni. Ukwazi kanjani ukuba ukhethe futha ukuze kahle, kungaba uhlanganiswe ukudonsa esiteshini futhi ngokuzenzakalelayo ngokugcwele inqubo yokuthola amanzi emthonjeni ovela ngaphansi komhlaba. On ukukhethwa sokunene futhi uzobe okuxoxwe ngazo kulesi sihloko.

Ngesisekelo Ukukhetha

Ngaphambi ushona esitolo ukuthenga, kudingeka unqume ukuthi kwamanye amaphuzu ayisihluthulelo benzela nenqubo yokukhetha. Nampa:

- ibanga ukusuka kahle empompini. Njengoba for imitha ngalinye ipayipi obuphelele akhawunti for a ingcindezi ukulahleka ezithile, akunakwenzeka ukuba indiva lesi silinganiso;

- the umthamo wamanzi otholwa. Kufanele sithole ikhadi lasebhange, okusho bafunde ngokuzibonela mathupha, lokho isikhathi esithile kukhona ukugcwaliswa womthombo noma imithombo. Ngokusobala, akunandaba mqondo ukuze uthole futha ngokweqile kahle nge nomqulu omncane wamanzi kanye owumthelela ezincane - konke kumelwe alinganisele;

- ukujula kusuka phansi kuya etafuleni amanzi;

- ivolumu eseduze yokuqothulwa. Kufanele singadluli ukudonswa kwemali.

Zonke lezi idatha anele, uma kunesidingo, umxhumanisi bangasiza sithole choice of ukuguqulwa ledzingekako imishini ukudonsa.

Indlela ukukhetha futha for kahle

Zonke izixazululo ekhona ngoba usinika amanzi kusuka emithonjeni komhlaba zingahlukaniswa zibe izinhlobo ezimbili - ngwenya futhi ebusweni. Ukwakhiwa kwehlelo sokuqala sihilela ukubeka idivayisi kukholamu amanzi, okwesikhashana ku ikhebuli ekhethekile. Lesi sakamuva, esikhundleni salokho, akuzona hermetic kanye nabo umswakamo motor Windings kungalimala. Ngaphezu kwalokho, isimiso wokusebenza ihlukile, futhi amakhono idivayisi ngamunye. Ngokwesibonelo, yasendlini amaphampu ngwenya kungenzeka vibration (version engabizi kakhulu), auger (ebucayini design) kanye centrifugal. Surface ngakho abakwazi ukuqhosha nensada. Ngakho-ke, ukukhuluma mayelana nendlela ukhetha futha for kahle, thina uzokhuluma onobuhle ngwenya.

Zonke lezi amaphampu babe nemingcele main ezimbili kuphela ukuthi nomthelela ekusebenzeni kwe-sonke isimiso - kuyinto ingcindezi okuzisholo kanye nokusebenza. Amanani Inani Eliphakeme isithakazelo kuphela ngokombono ezithile "ukuphepha wekhasi" - operation okuqhubekayo is hhayi Kunconywa kulezi izindlela. Ukutadisha umbuzo kanjani ukukhetha futha for kahle, kufanele sinake yokuthi izici ezimbili eziphawulwe ngenhla kakhulu ezithinta izindleko zokugcina zedivayisi.

Ngakho-ke, kwezinye izimo kunengqondo ukushintsha wesifunda kagesi (isibonelo, ukuhlela kahle accumulator), hhayi overpaying ngoba futha namandla kakhulu.

Ngwenya iphampa ngoba imithombo. Ukukhethwa nemingcele

Ake sithi ibanga "indawo - nesibuko yamanzi" 16 m, futhi kuze kube seqophelweni yamanzi uzotshala (emile) -. 20 m othile abstract ngwenya futha, amelwe esitolo okwaziyo ukukhulula 2500 amalitha ngehora ngesikhathi inhloko amamitha 60. Ingcindezi ukulahlekelwa bakholwe 1 emkhathini oluhambisana ukwanda ukuphakama 10 m, kanye umugqa ovundlile - kancane izikhathi 10.

Ngenxa yalesi imodeli, nge, ikhanda lalo 60 m kuleyo ndawo yokuhweba ye iphayiphi ngeke 60-16-2 = 42 m, noma 4.2 atm. Uma sicabangela ushintsho kanye ematfuba, sigcina sesifana 4 atm. Njengoba kuyinsakavukela esiphakathi 3 kanye 4 eziphindwe, lokhu imodeli awunankinga.

Inani lamanzi enikeziwe ingabalwa usebenzisa uhlelo enamathiselwe ishidi idatha. Njengoba kunqunywa ekulahlekelweni (16 + 2 = 18 m) kuyadingeka kusukela leli phuzu ukudweba umugqa kugrafu we ijika kanye iphuzu yemigwaqo, - perpendicular nezinye axis. Thola ukusebenza.
