Ukulungelelanisa i-booster yamanzi echibini lase-china i-slurry pump station kunye nokuhanjiswa okuphuculweyo
Kwisixeko sasezintabeni, ngenxa yomahluko wokuphakama komhlaba phakathi kweempompo eziludaka eziphakamileyo zaseChina, ukhetho lwempompo oluludaka lwaseChina kufuneka luqaphele oku kulandelayo engqondweni: Xa ukhetha iimpompo zodaka lwaseChina, ukonga umbane kufuneka kuqwalaselwe xa ubungakanani obukhulu kunye notshintsho loxinzelelo. isantya sinokusetwa , buyisela i-impeller blade uhlengahlengiso lwemilinganiselo yohlengahlengiso ;xa usebenzisa i-partitioning partition pressure of water , impompo eludaka lwase-china kufuneka ikhethwe amaqela amaninzi emimandla yoxinzelelo eyahlukeneyo yayingamanzi, ukunciphisa ukusetyenziswa kwamandla.
Xa umphakamo womhlaba ungaphezulu kwe-20m, impompo yodaka lwaseChina iyonke inkulu kakhulu, isantya sokuhamba kombhobho sikhulu kakhulu, imibhobho emide kakhulu kunye nomhlaba utshintsha izikhululo zokumpompa eziludaka lwaseChina kwivalve zivala ngokukhawuleza kakhulu kwaye ziqhelene nokumisa uludaka lwaseChina. ukupompa amanzi ngehamile iingozi ezibangelwayo / 0 amanzi abalekayo , ngaphandle kwamanzi, i-submerged china izikhululo zokumpompa i-slurry, umonakalo wezixhobo.Indawo yempompo eludaka lwaseChina kufuneka ibekwe iivalvu zokuvala okucothayo kunye nesinqamuli sehamile samanzi okanye ivalve yokukhangela ecinyiweyo ukunqanda umonakalo ngenxa yehamile yamanzi ebangelwa ziimpompo zodaka lwaseChina kunye nokuvuza kwemibhobho.Ukulawula izakhiwo ezichongiweyo kuyilo womnatha wombhobho, ububanzi bombhobho buchongwa yi-traffic ephezulu kakhulu, kwaye ngenye imini i-traffic ephezulu imfutshane kakhulu, ngaloo ndlela ibangela ukusebenza kakuhle kwamandla kunye nomthamo wamanzi womnatha wombhobho kunye ne-china slurry pump ayikho phezulu, kodwa nje ukunciphisa i-traffic kuya kuphakamisa ukunyuka, okukhokelela ekunyukeni koxinzelelo kumbhobho, okubangela inkcitho yokusetyenziswa kwamandla kunye nokukhupha.
Ukwenzela oku kungasentla, ukuthatha unikezelo lwamanzi olujikelezayo lwe-china slurry izahlulelo zempompo nazo zinokusetwa ukunyenyisa isakhiwo ( ichibi eliphezulu , iinqaba zamanzi , ichibi elilawulayo , njl. njl. ) .Oku kukwavumela unikezelo lwamanzi ngakumbi izikhululo zokumpompa amanzi eChina , imibhobho yamanzi kunye neengcingo ezinkulu ukunciphisa umbhobho , kunye nokuphucula ukuthembeka kothungelwano lwemibhobho yonikezelo lwamanzi .Xa i-coefficient of variation yenethiwekhi yombhobho wamanzi Kh> 1.5 , isethi malunga nokulungelelanisa isakhiwo sinokugcina ngaphezu kwe-30%, ngelixa i-Kh <1.1, awulungelelanisi izakhiwo ezimiselweyo.Lungisa indawo kunye nobukhulu bezakhiwo kwizicwangciso zenethiwekhi yombhobho kwaye ukhethe imfuneko yokulungelelanisa isakhiwo kunye nomthamo , ubuninzi, indawo kufuneka igqitywe ngothelekiso lwezoqoqosho kunye nobugcisa, khetha izikhululo zokumpompa i-china slurry, imibhobho, ukulungelelanisa izakhiwo zeendleko zobuninzi bephondo. iinkqubo .
Ukulungelelanisa isakhiwo ukumisela indawo kufuneka kuthathelwe ingqalelo le miba ilandelayo: izakhiwo zolawulo kufuneka zibekwe kwindawo ephezulu yendawo yokubonelela ngamanzi, kangangoko kunokwenzeka I-Heights pool;izakhiwo zolawulo kufuneka zibekwe kufutshane nabasebenzisi bamanzi abakhulu kwaye abasebenzisi bafuna uxinzelelo oluphezulu;izakhiwo zokulawula ekufanele zibekwe kwisithili samanzi;izakhiwo zolawulo kufuneka zilungelelaniswe kunye neendawo zonikezelo lwamanzi izakhiwo zomhlaba ithambeka i-i1 kunye ne-i2 ephezulu yamanzi kwiindawo zokulawula i-hydraulic gradient inokuba, xa i-i1/i2 <1:00, ibekwe kwindawo ephezulu;xa i1/i2> 1:00 , ibekwe kwindawo yesithili samanzi.
Lungisa isakhiwo ukumisela amandla okulungelelanisa umthamo kunye nosuku lokungena kunye nokuphuma ukulungelelanisa isakhiwo sesantya sokuhamba.Xa umbhobho kuphela izakhiwo ezilawulayo unokutshintsha kwisixa samanzi kunye namanzi afunyenweyo , kufuneka ithathele ingqalelo impembelelo yotshintsho kwinqanaba lamanzi echibini lase-china slurry pump , ukulungiswa kwesakhiwo ukulungelelanisa umthamo kule fomula ilandelayo ukuqikelela : I-WT = (1-A) Q (d1 + d2) 100 (7) apho i-A iyinto yokulungelelanisa ukuqwalasela i-centrifugal ngokwayo, ebonisa ukuhla kwe-lift okanye intloko inyuswe ukunciphisa izinga lokuhamba kwandisa uphawu lwezinga lokuhamba;Q yinqanaba lokuhamba koyilo (m3 / d);I-D1, i-d2 ngowona mgangatho uphezulu wolungelelwaniso lonikezelo lwamanzi oluqokelelweyo kunye nesikhululo sombhobho wesikhululo sokumpompa se-china umahluko ukuya kwi-% Q imitha.
Bala ubuninzi bamanzi emihla ngemihla ukungena nokuphuma kwiyure nganye ukulungisa ukuhamba kwetrafikhi ukungena nokuphuma kwi-cumulative flow, bendiphelelwe luhlengahlengiso kwiiyure zokuqala zolwakhiwo lwamanzi i-vWi, zonke iiyure zolungelelwaniso oluqhubekayo lwezakhiwo ukulungisa uhlengahlengiso. umthamo vWi.Idityaniswe namanzi omlilo inako izakhiwo kufuneka zilungelelanise umthamo .Ukulungelelanisa ukuphakama kwesakhiwo kunokuba ngokukhululekileyo iimfuno zeendawo zokulawula iSithili saManzi ukumisela uxinzelelo lwamanzi.Njengoko uthungelwano lwemibhobho yentaba yomthi ngakumbi, ulawulo lokuhamba phakathi kweendawo ezahlukeneyo zothungelwano lwemibhobho lunesakhono esilambathayo sokunciphisa ukuthembeka konikezelo lwamanzi, kunye nenkcitho yamandla.Ngoko ke, kufuneka sisebenzise ngokupheleleyo idama , njengokulungelelanisa umgangatho wokukwazi kwesakhiwo ukulawula ukuhamba kunye noxinzelelo lokuphucula amandla othungelwano lokuzilawula , kunye nokusebenzisa umhlaba ukuya kwabahluphekileyo baxhomekeke kunikezelo lwamanzi omxhuzulane. wombhobho womnatha ukwenzela ukugcina amandla .
Isiphelo Malunga nentaba yamanzi , ngenxa yokuba izikhululo zokumpompa ezibini zaseChina zithumela kumazwe angaphandle ukuya kweyona ndawo imbi yomahluko wobude bomhlaba , unikezelo lwamanzi lwesithili ngokubanzi kunye nokuseta izikhululo ezilawula uxinzelelo kunye nezakhiwo .Embindini wezikhululo zokumpompa zaseChina eziludaka kunye ne-booster china uqwalaselo lwesikhululo sempompo , ulwahlulo kufuneka lusekwe kwimeko eyiyo kunye nemizobo yothungelwano lombhobho , ngokusebenzisa imidibaniso eyahlukeneyo ye / 0 ilingana nokuthelekisa uqoqosho lwase china impompo yodaka ukukhetha uludaka lwase china iimpompo.Lungisa indawo yesakhiwo kufuneka imiselwe ngokwendawo kunye nomhlaba ngaphakathi kombhobho wombhobho we-china slurry pumping stations kunye namanzi;lungisa umthamo ngefomula WT = (1-A) Q (d1 + d2) 100 Kulungile.
