Intloko Impompo: ukuchaza indlela yokusebenza?

Ukukhetha impompo ekunene nayiphi na injongo kufuna ukubalwa yokusebenza kwayo. Wayofika, uxinzelelo lwamanzi kwi impompo hlengiswe ukuze xa ubuninzi ixabiso layo esandleni akuthethi ukubhabha zokutshiza, yaye kwangaxeshanye musa ukuba ulinde ixesha elide zokugcwalisa Izikhongozeli ezikhulu. Ukuze ufumane inkcazelo engakumbi ukujonga njani ukusebenza lokumpompa, yaye siza kuthetha kamva kweli nqaku.

parameters Ukhetho Pump

Fumana eyiyo intloko pump ngeendlela ezimbini: isixhobo uhlangabezane ngumntu okanye ukukhetha echanekileyo yemida. Ukuba ukhetha ngawo umgaqo "omnye ngcono ukuba ummelwane", ngoko kusenokwenzeka ukuba jet intloko ebuthathaka xa ukufakwa amanqaku eziliqela losetyenziso. Noba kuya kusithintela ukuhamba kwamanzi kwenxenye crane zinonxibelelwano ukuba kunciphisa ukusebenza lesixhobo ke kwandisa iindleko mali ngexesha emsebenzini wayo.

Indlela yobungcali umba yonikezelo lwamanzi kufuna ingqalelo imiba emininzi;

• ukumpompa imveliso;
• Ebubanzini ithumbu flow;
• line ubude;
• Inani nokumila nokufakwa kwayo;
• inani impompo.

Ngokuqhelekileyo, abanikeli nzima kakhulu, ngoko ke inkqubo entsonkothileyo ngemibhobho yonxibelelwano ukuba zisetyenziswe ngokupheleleyo iimpompo ezininzi. Ngalinye lenza umsebenzi wayo, omnye uzalisa itanki inani amanzi equleni, omnye inika amanzi ekhaya, le yamanzi umyezo wesithathu.

Iinkcukacha yentloko lwempompo

Iimpompo aneempawu ezininzi. Ukuze ukuba umboleki ukuba loluphi uhlobo yesixhobo kuyimfuneko, kukho izikhombisi ezisisiseko embalwa:

1. Umthamo lomxhesho lulwelo okanye pump. Ibonisa inani lamanzi kangangexesha elithile ixesha elizenzekelayo iyunithi. Oku kwakuthetha ukuba kulwelo aqukuqela ngqo kwisixhobo kwimveliso. Ukuze ubone ivolyum ekupheleni komgca, kuyimfuneko ukuthabatha nethontsi uxinzelelo kwi yokugqibela.
2. Ubukhulu xi okanye uxinzelelo. Ibonisa indlela ephakamileyo pump uyakwazi phakamisa amanzi. Oku akubandakanyi ukuphakama isixhobo ukuya kwinqanaba amanzi smooth komhlaba.
3. Ukuphakama amanzi ucingo okanye chweba. Umgama ukusuka phezu kwamanzi lo walivala ithende sokufunxa amanzi esatsiba lichazwa ngokungqongqo - uhola abangaphezu kwemfuneko imbonakalo unit kwi cavitation indawo yokusebenzela. It Ungatshintsha iimpawu ezibalulekileyo kwimpompo, okanye nje akayi kuvumela ukuba amanzi. Chweba angandiswa ngokumisela kwimpompo abangabancedani phambi engundoqo, ngqo kwindawo sokufunxa. Kanye nomphumela ofanayo ifunyenwe xa kudalwa koxinzelelo lomoya ngumntu ngaphakathi ichibi fluid.
4. ukusetyenziswa kwamandla amandla.

Ngamagqabantshintshi iimpompo

Iimpompo kufuneka zihlelwe ngokungqinelana nomgaqo amanyathelo, iimpawu zoyilo kunye nokusetyenziswa ekujongwe. Kwakhona, kukho iiyunithi ngwenya kunye komhlaba. Bonke bephela zenzelwe zokumpompa amanzi, kodwa inkoliso akabakhathalele layo nje kuphela, kodwa kwakhona ukunyuka kwamanzi ezinzulwini ezahlukeneyo:

• Iimpompo for emithonjeni. Ngokomthetho Akayomizekelo ngwenya. Luphawulwa yokuba bakwazi ukuphakamisa amanzi anzongonzongo kakhulu (ukuba akukho zithintelo) ngokuxhomekeke kumandla yeyunithi yamandla. Yenza uxinzelelo enamandla ezisendleleni.
• Drenazhniki. Yiba yokusebenza ephezulu, kodwa ayenzelwanga ukwenza uxinzelelo oluphezulu, uxinzelelo oluphezulu musa ukumnika. Lula kuloo manzi amdaka unako ampontshwe kunye ngamasuntswana amancinci emzimbeni.
• Centrifugal. Universal iimpompo. Ngaba ingasetyenziswa njengako amaqula, nangenxa yokumpompela ulwelo ichibi. Le amanzi abawathobanga kwaye mda yi umgama ukusuka kumphezulu emnyango kumphezulu umbhobho ofunxayo amanzi. Intloko yokumpompa ixhomekeke kwinani impellers namandla injini, kodwa abanako ukuvusa ikholam amanzi ngaphezulu kweemitha 120.
• Umsinga. Ngokufanayo centrifugal, kodwa kukho nezinye impeller elilungelelanisiweyo. Xa injini amandla asezantsi zibonelela intloko ophezulu kunye nesikhundla. Nyusa a column yamanzi phezu 160 m. Ububi ifuna yokusulungeka.
• Kwegazi. Musa phakamisa amanzi anzongonzongo, kodwa kudala uxinzelelo ethile kunye nokusebenza kwiqondo lobushushu ephakamileyo.

Iimpompo: supply, uxinzelelo

Mhlawumbi ayingabo bonke uyazi, kodwa iimpompo asebenza ngokubambisana kunye yengcinezelo umoya. Bathi yenza nje i indawo obhobhozayo kunye nokugxothwa. Ngoko, nantoni na imigudu ukuze baye encotsheni, besebenzisa iiyunithi zinamandla, kuphakanyiswe amanzi anzongonzongo kakhulu ngeke isebenze. Xa amandla xi womoya kuhambe amandla womxhuzulane, amanzi ithumbu ayeke. Ukuze kuphakanyiswe ukusuka ezinzulwini ukusebenzisa izithuthi enamandla ngwenya, ukudala uxinzelelo.

Ezona mpawu ziphambili iiyuthi ezichazwe kukho intsebenzo pump xi. Bona babe nolwalamano ethile phakathi. Ngenxa yoko, phantsi koxinzelelo kuthethwa ukuba nakho kubonelela ngamanzi ukuya kubude ethile okanye sihambe ngendlela tyaba yi ubude kwangaphambili. Kuyaqondakala ukuba impompo efanayo uya kuvelisa uxinzelelo eyahlukileyo kwi-20 m 120.

Uxinzelelo kufuneka ukwazi, ukukhetha uhlobo pump. imodeli ngalinye linga ukudala uxinzelelo ukubabomelele, bangamaphakuphaku, ngenxa kuyilo kwendlela yokusebenza. Xa ulwelo iza adibane ivili nesimbo okanye inwebu okanye piston, ukuba ufumana intlawulo ye-eneji ethile agciniweyo, nto leyo iphakamisa it up.

Inkqubo kakhulu ngempumelelo centrifugal kunye impellers eziliqela ezilandelelanayo. Bona - kongeza uxinzelelo lwempompo yaye ukusebenza eliphezulu kakhulu.

Indlela yokulawula uxinzelelo

Kufuneka ukunyenyisa okudalwa kwimpompo kuyo nayiphi na inkqubo ngamanzi ezintsonkothileyo. Kuba eziphembelela intloko kukho iindlela ezine:

1. Nobunzima. Indlela sikuko yokuba ifowuni output okanye umbhobho ofunxayo efakiweyo ziliminxe okhethekileyo. kwimpompo abaqhelekileyo kwenza indima yakhe. Kwisiza ufakelo, kuxhomekeka ubukhulu emngxunyeni orifice, inxenye xi bungacinywa. Xa isikhundla bayeke amanzi ngamashishini pump i ukusebenza ukuhla yesixhobo, njengoko impompo odla koxinzelelo njengoko kakhulu kwi buthathaka inkqubo yamandla ombane.
2. ulawulo wombane isantya impeller. Le yeyona ndlela isebenzayo ngaphandle kokulahleka ngobuchule pump. Ubonelelo lwamanzi kuyehla ekuncitshisweni umlinganiselo kusetyenziso ngamandla.
3. Isantya ukunciphisa Mechanical. Kulo mzekelo, sebenzisa izixhobo ekunciphiseni. Le ndlela disadvantageous ngokwezoqoqosho - kuba injini kuyidla amandla efanayo yaye kufuneka yindlela eyongezelelweyo - gearbox.
4. Badlule. Phakathi iplagi kunye nempompo sokufunxa ityhubhu umakad abulawe. Kubonakala ukuba ezinye engamanzi ngomtshini nje ngaphandle ekwenzeni umsebenzi luncedo. Ngenxa yoko, uxinzelelo kwi kwimibhobho unciphisa, kunye nokusebenza uvikivwa.

Kuza kuba uxinzelelo kwi kwimpompo iimpompo amanzi avela phezulu

Xa amandla inani amanzi ngaphezu indawo yokufaka kwenkqubo lokumpompa, oko phantse zingashiyi namandla ukufunxeka. Emva koko, ukubala yengcinezelo impompo, sebenzisa ifomula ilandelayo:

Lim = + Ngeo Npoter + Nsvob - tank Nvysota.

ixabiso xi efunekayo ngenxa yeendleko umboleki - NPT apha.

Ngeo - umahluko kwinqanaba phakathi impompo kunye neqonga ufakelo ephezulu indawo zokungenisa amanzi.

Npoter - ilahleko ekungameleni imikhosi zochuku ngaphandle kwecandelo umgca kwemali lwencwadi phayiphu ukusuka itanki unikezelo ukuya impompo.

Nsvob - intloko amanqaku ngesifo kunye nokuvulwa ngokupheleleyo.

itanki Nvysota - ukuphakama phakathi itanki kunye nempompo.

Inaliti amanzi onobunzulu

Indlela ukufumanisa intloko pump ngexesha zokumpompa amanzi equleni, libe sisigingqi vodonakopitelnoy nasemaquleni? Ifomula Ukubala kuthatha uhlobo kulandelayo:

NPT = Ngeo Npoter + + + Nsvob Nuroven umthombo.

Kuyo, yonke imiqathango ayafana, ngaphandle yokugqibela omnye - Nuroven mthombo - nto leyo umahluko phakathi kwindawo esingena fluid neendlela sokumpompa amanzi.

Yintoni na isikhululo sokumpompa

Kwesikhululo sokumpompa yinkqubo kwimpompo kunye netanki yiHydraulic, ukusebenza ngababini. Plus, yinto iswitshi xi okhethekileyo. Ibhetri ke lisebenza njengentloko pump mpuluswa element yiHydraulic, ukuthintela ziguquka rhoqo kwi injini yombane kwaye ilungelelanise hammering kunokwenzeka unxibelelwano ngemibhobho yamanzi.

Kwizikhululo ekunokuthi kusekelwe kulo naluphi na uhlobo na impompo, ukusebenzisa nayiphi na imiqulu kwebhetri. Itanki mkhulu umkhosi lift ngakumbi ezongezelelweyo eyilwe ngabo.

isiphelo

Xa uxinzelelo amanzi kwimpompo asanelanga, kunokwenzeka ukuba yiphose phandle, ukufakela iiyunithi ezimbini okanye ngaphezulu series. Loo scheme isoloko isetyenziswa for equleni apho emazantsi enyusiweyo unit ngwenya enikezela amanzi ukuya sokufunxa wawelela a centrifugal.
