Xa impompo ye-centrifugal iqaliswa, akukho manzi kumbhobho wokuphuma wempompo, ngoko akukho kuxhathisa kwemibhobho kunye nokuphakama kokumelana nokuphakama. Emva kokuba impompo ye-centrifugal iqalisiwe, intloko yempompo ye-centrifugal iphantsi kakhulu kwaye ukuhamba kukhulu kakhulu. Ngeli xesha, ukukhutshwa kwe-motor yepompo (amandla e-shaft) kukhulu kakhulu (ngokwe-curve yokusebenza kwempompo), ekulula ukuyilayisha, okuya kulimaza i-motor yepompo kunye nesekethe. Ngoko ke, vala ivalve yokuphuma xa uqala, Ukuze wenze impompo isebenze ngokuqhelekileyo. Ukuvala i-valve yokuphuma ilingana nokuseta ngokusemthethweni uxinzelelo lokumelana nombhobho. Emva kokuba impompo isebenze ngokuqhelekileyo, qalisa ngokukhawuleza ivalve ukwenza impompo isebenze ngokuqhelekileyo inyathelo ngesinyathelo kunye nomthetho wegophe layo lokusebenza.
Amanqaku amabini kufuneka aqinisekiswe ngaphambi kokuqala impompo ye-centrifugal:
1. Gcwalisa i-casing yempompo ngamanzi ukwenza i-vacuum;
2. Ivalve kumbhobho wokuphuma kwamanzi kufuneka ivalwe ukwenzela ukuba impompo yamanzi ingenzi ukuhamba, okunokunciphisa i-motor yokuqala yangoku kwaye iququzelele ukuqala kakuhle kwempompo yamanzi. Ngokuqala kakuhle kwempompo yamanzi, ivalve yesango kufuneka ivulwe ngokucothayo nangexesha.
Impompo ye-Centrifugal ixhomekeke ekufunxeni kwevacuum eyenziwe yi-centrifugal force ye-impeller ukuphakamisa amanzi. Ngoko ke, xa uqala impompo ye-centrifugal, kufuneka uqale uvale i-valve yokuphuma kwaye ugcwalise amanzi. Xa umgangatho wamanzi udlula indawo ye-impeller, ipompo ye-centrifugal inokuqaliswa kuphela emva kokuba umoya kwipompo ye-centrifugal ukhutshwe. Emva kokuqala, i-vacuum yenziwa malunga ne-impeller ukufunxa amanzi, anokuvulwa ngokuzenzekelayo kwaye aphakamise amanzi. Ngoko ke, ivalve yokuphuma kufuneka ivalwe kuqala.
Malunga nempompo ye-centrifugal:
Impompo ye-Centrifugal yimpompo ye-vane, exhomekeke kwi-impeller ejikelezayo. Kwinkqubo yokujikeleza, ngenxa yokusebenzisana phakathi kwe-blade kunye ne-liquid, i-blade idlulisela amandla omatshini kumanzi, ukwenzela ukuba uxinzelelo lwamanzi lunokwandiswa ukufezekisa injongo yokuhambisa i-liquid. Impompo ye-centrifugal inezi mpawu zilandelayo:
1. Kukho ixabiso elilinganiselweyo lentloko eyenziwa yipompo ye-centrifugal kwisantya esithile. Ukuhamba kwendawo yokusebenza kunye namandla e-shaft kuxhomekeke kwimeko yenkqubo yesixhobo exhunywe kwimpompo (umahluko wezinga, ukuhluka koxinzelelo kunye nokulahleka kwemibhobho). Intloko iyahluka ngokuhamba.
2. Ukusebenza okuzinzileyo, ukuthutha okuqhubekayo, kwaye akukho pulsation yokuhamba kunye noxinzelelo.
3. Ngokuqhelekileyo, ayinayo i-self-priming capacity. Kuyimfuneko ukugcwalisa impompo ngolwelo okanye ukutshayela umbhobho ngaphambi kokuba uqale ukusebenza.
4. Impompo ye-centrifugal iqalwa xa ivalve yokukhupha umbhobho ivaliwe, kwaye impompo ye-vortex kunye ne-axial flow pump ziqaliswe xa ivalve ivuleke ngokupheleleyo ukunciphisa amandla okuqalisa.
Ngaphambi kokuba impompo iqaliswe, igobolondo lempompo lizaliswe ngolwelo oluthuthwayo; Emva kokuqalisa, i-impeller ijikeleza ngesantya esiphezulu esiqhutywa yi-shaft, kwaye i-liquid phakathi kwee-blades kufuneka ijikeleze nayo. Ngaphantsi kwesenzo samandla e-centrifugal, i-liquid iphonswa ukusuka kumbindi we-impeller ukuya kumda wangaphandle kwaye ifumana amandla, ishiya umda wangaphandle we-impeller ngesantya esiphezulu kwaye ingene kwi-volute pump housing.
Kwi-volute, i-liquid iyancipha ngenxa yokwandiswa ngokuthe ngcembe komjelo wokuhamba, iguqula inxalenye yamandla e-kinetic ibe yi-static yamandla oxinzelelo, kwaye ekugqibeleni igeleza kumbhobho wokukhupha kwixinzelelo eliphezulu kwaye ithunyelwe kwindawo apho ifuneka khona. Xa i-liquid ihamba ukusuka kumbindi we-impeller ukuya kumda wangaphandle, i-vacuum ethile yenziwa embindini we-impeller. Ekubeni uxinzelelo olungaphezulu kwinqanaba lolwelo lwetanki yokugcina lukhulu kunoxinzelelo kwi-inlet yempompo, i-liquid igxininiswe ngokuqhubekayo kwi-impeller. Ingabonwa ukuba nje ukuba i-impeller ijikeleza ngokuqhubekayo, ulwelo luya kufunxwa kwaye lukhutshwe ngokuqhubekayo.
Ukuqaliswa kwezinye iimpompo ze-centrifugal:
Ezi zikhankanywe ngasentla ziimpompo ze-centrifugal. Ngolunye uhlobo lweempompo, imeko imi ngolu hlobo lulandelayo:
Iimpawu zokuqalisa ukuhamba okukhulu kwempompo ye-axial flow 01
Xa i-valve evulekileyo epheleleyo iqala i-axial flow pump, amandla e-shaft ngowona mgangatho uphezulu phantsi kwemeko yokuhamba kwe-zero, eyi-140% ~ 200% yamandla alinganisiweyo we-shaft, kwaye amandla awona mncinci kubuninzi bokuhamba. Ngoko ke, ukuze kucuthwe umsinga oqalayo, uphawu lokuqala lwamandla e-shaft kufuneka lube luhamba olukhulu oluqalayo (okt ivalve evulekileyo egcweleyo iqala).
02 iimpawu zokuqalisa zempompo yokuhamba okuxutyiweyo
Xa umpompo wokuhamba okuxutyiweyo uqalwa ngevalve epheleleyo evulekileyo, amandla e-shaft aphakathi kweepompo ezimbini ezingentla apha phantsi kwemeko yokuhamba kwe-zero, eyi-100% ~ 130% yamandla alinganisiweyo. Ngoko ke, iimpawu zokuqala zompompo wokuhamba okuxutyiweyo kufuneka kwakhona zibe phakathi kweepompo ezimbini ezingentla, kwaye kungcono ukuqala nge-valve evulekileyo epheleleyo.
Iimpawu ze-03 zokuqalisa zempompo ye-vortex
Ivalve evulelekileyo iqale impompo ye-vortex inamandla aphezulu eshaft phantsi kwemeko yokuhamba kuka-zero, eyi-130% ~ 190% yamandla alinganisiweyo eshaft. Ngoko ke, ngokufana nempompo yokuhamba kwe-axial, uphawu lokuqala lwempompo ye-vortex kufuneka ibe sisiqalo sokuqukuqela esikhulu (okt isiqalo sevalvu evulekileyo epheleleyo).
