Indlela yokufaka impompo yamanzi yokungena kunye nemibhobho yokuphuma?
Xa kufakwe umbhobho ophumayo wempompo yamanzi, umbhobho wedayamitha eguquguqukayo kufuneka ube ngumbhobho oguquguqukayo wedayamitha ephakathi, kwaye umbhobho werabha oguquguqukayo kufuneka udityaniswe kwizibuko lempompo ukunciphisa amandla okungcangcazela agqithiselwe kumbhobho ngenxa yokungcangcazela kwempompo, kunye Igeyiji yoxinzelelo kufuneka ifakwe kumbhobho omfutshane phambi kwevalve, kwaye ivalve yokukhangela kunye nevalve yesango (okanye ivalve yokumisa) kufuneka imiselwe kumbhobho wokuphuma. Umsebenzi wevalve yokutshekisha kukuthintela amanzi ombhobho wokuphuma ukuba abuyele kumpompo kwaye achaphazele i-impeller emva kokuyeka umpompo. Iskimu sofakelo lombhobho wokungena kumbhobho wamanzi siyafana: impompo yofakelo lombhobho wokuzibophelela yeyona nto ibalulekileyo echaphazela uluhlu lokufunxa lwempompo eziziqalayo, ufakelo aluvuzi kakuhle, umbhobho mde kakhulu, ungqindilili kakhulu, uncinci kakhulu, inani lengqiniba kunye nesidanga ingqiniba iya kuchaphazela ngqo impompo self-priming ukufunxa amanzi. I-1, ipompo enkulu yomlomo we-self-priming kunye nombhobho omncinci wamanzi unikezelo lwamanzi abantu abaninzi bacinga ukuba oku kunokuphucula eyona ntloko yempompo ye-self-priming, intloko yangempela yempompo ye-self-priming centrifugal = intloko epheleleyo ~ ukulahlekelwa kwentloko. Xa uhlobo lwempompo lunqunywe, intloko epheleleyo iqinisekile; Ilahleko yentloko ibalulekile ekuchaseni umbhobho, i-diameter encinci yombhobho, ukuchasana okukhulu, ngoko ke ilahleko enkulu yentloko, ngoko ukunciphisa ububanzi, intloko yangempela yempompo ye-centrifugal ayikwazi ukunyuka, kodwa iya kuncipha, okubangela ukuthotywa kwempompo yokuzenzela yodwa. Ngokufanayo, xa umpompo wamanzi omncinci we-diameter encinci usebenzisa umbhobho omkhulu wamanzi ukupompa amanzi, awuyi kunciphisa intloko yokwenene yempompo, kodwa iya kunciphisa ukulahlekelwa kwentloko ngenxa yokunciphisa ukuchasana kwemibhobho, ukwenzela ukuba intloko yangempela iphuculwe. . Kukho noomatshini abacinga ukuba xa iimpompo zamanzi ezinobubanzi obuncinci zinemibhobho yamanzi emikhulu, ziya kwandisa kakhulu umthwalo wemoto. Bacinga ukuba ububanzi bombhobho buyanda, amanzi kumbhobho wokukhupha amanzi aya kwenza uxinzelelo olukhulu kwi-impeller yepompo, ngoko kuya kwandisa kakhulu umthwalo wemoto. Njengoko wonke umntu uyazi, ubungakanani boxinzelelo lwe-liquid bunxulumene kuphela nokuphakama kwentloko, kwaye akunanto yakwenza nobukhulu bombhobho we-cross-sectional area. Ngethuba nje intloko iqinisekile, ubukhulu be-impeller yempompo ye-self-priming ayitshintshi, kungakhathaliseki ukuba ubukhulu bombhobho bukhulu kangakanani, uxinzelelo olusebenza kwi-impeller luqinisekile. Nangona kunjalo, ngokunyuka kobubanzi bombhobho, ukuchasana kokuhamba kuya kuncitshiswa, kwaye izinga lokuhamba liya kwandiswa, kwaye iindleko zamandla ziya kwandiswa ngokufanelekileyo. Kodwa ngokude nje kwinqanaba elilinganisiweyo lentloko, kungakhathaliseki ukuba ukunyusa ububanzi bempompo kunokusebenza ngokuqhelekileyo, kwaye kunokunciphisa ilahleko yombhobho, ukuphucula ukusebenza kwempompo. 2. Xa ufaka i-self-priming pump yokungenisa impompo yamanzi, iqondo leqondo okanye i-warping ephezulu iya kwenza umoya uqokelelwe kumbhobho wokungena, i-vacuum yombhobho wamanzi kunye nempompo ye-centrifugal, ukuze intloko yokufunxa yempompo ye-centrifugal. iyancipha kwaye imveliso yamanzi iyancipha. Indlela echanekileyo yile: iqondo lecandelo kufuneka lithambekele kancinane kwicala lomthombo wamanzi, akufanele libe sisidanga, ngakumbi ukuba lingathambeki phezulu. 3. Ukuba ii-elbows ezininzi zisetyenziselwa umbhobho wokungena kwamanzi wempompo ye-self-priming, ukuchasana nokuhamba kwamanzi kwendawo kuya kwandiswa. Kwaye i-elbow kufuneka ijike kwicala elithe nkqo, ungavumelani nokujika kwi-degree degree, ukuze ungaqokeleli umoya. I-4, i-self-priming pump inlet idibaniswe ngokuthe ngqo kunye ne-elbow, eya kwenza ukuba amanzi ahambe nge-elbow kwi-impeller engalinganiyo. Xa i-diameter ye-inlet ye-inlet inkulu kune-inlet yempompo yamanzi, umbhobho wokunciphisa i-eccentric kufuneka ufakwe. Inxalenye ecaba ye-eccentric reducer kufuneka ifakwe phezulu, kwaye inxalenye ethambekele kufuneka ifakwe phantsi. Ngaphandle koko, qokelela umoya, unciphise ubuninzi bamanzi okanye umpompe amanzi, kwaye ube nesandi sokuphahlazeka. Ukuba ububanzi bombhobho wokungena kwamanzi bufana nokungena kwamanzi kwimpompo, umbhobho othe ngqo kufuneka wongezwe phakathi kokungena kwamanzi kunye ne-elbow. Ubude bombhobho othe tye akufanele bube ngaphantsi kwama-2 ukuya kuma-3 ububanzi bombhobho wamanzi. I-5, impompo ye-self-priming ifakwe i-valve ephantsi yombhobho wokungena kwamanzi icandelo elilandelayo alikho nkqo, njengale fakelo, i-valve ayikwazi ukuvalwa ngokwayo, ibangela ukuvuza kwamanzi. Indlela yokufakela echanekileyo yile: ixhotyiswe ngevalve engezantsi yombhobho wokungena kwamanzi, icandelo elilandelayo lilo elithe tye. Ukuba ukufakela ngokuthe nkqo akunakwenzeka ngenxa yeemeko zomhlaba, i-Angle phakathi kwe-axis yombhobho kunye ne-degree degree kufuneka ibe ngaphezu kwe-60 °. 6. Isikhundla sokungena kwi-self-priming pump water inlet pipe ayilungile. (1) Umgama phakathi kokungena kumbhobho wokuzibophelela wempompo yamanzi kunye nomzantsi kunye nodonga lombhobho wokungena wamanzi ungaphantsi kobubanzi bokungena. Ukuba kukho intlenga kunye nobunye ubumdaka emazantsi echibini, isithuba phakathi kwendawo yokungena kunye namazantsi echibini lingaphantsi kwe-1.5 ububanzi, oko kuya kubangela ukuba ukungenisa kwamanzi kungahambi kakuhle xa umpompa okanye ufunxa intlenga kunye nenkunkuma, ukuvala indawo yokungena. (2) Xa ubunzulu bokungena kwamanzi bombhobho wokungenisa amanzi bungonelanga, buya kubangela umphezulu wamanzi ojikeleze umbhobho wokungenisa amanzi uvelise amachibi, okuchaphazela ukungenwa kwamanzi kunye nokunciphisa ukuphuma kwamanzi. Indlela yofakelo echanekileyo yile: ubunzulu bokungena kwamanzi bempompo yamanzi encinci kunye nobukhulu obuphakathi abuyi kuba ngaphantsi kwe-300 ~ 600mm, kwaye impompo enkulu yamanzi ayiyi kuba ngaphantsi kwe-600 ~ 1000mm7. Indawo yokuphuma yempompo yogutyulo ingaphezulu komgangatho wamanzi oqhelekileyo wequla lokuphuma. Ukuba i-outlet yepompo ye-sewage ingaphezulu kwinqanaba eliqhelekileyo lamanzi kwi-pool yokuphuma, nangona intloko yepompo inyuswa, ukuhamba kuyancipha. Ukuba ukuphuma kwamanzi kufuneka kube phezulu kunomgangatho wamanzi we-outlet pool ngenxa yeemeko zendawo, i-elbow kunye nombhobho omfutshane kufuneka ufakwe emlonyeni wombhobho, ukwenzela ukuba umbhobho ube yi-siphon kunye nokuphakama kwendawo yokuphuma kunokwehliswa. 8. Impompo ye-self-priming ye-sewage enentloko ephezulu isebenza kwintloko ephantsi. Abathengi abaninzi bahlala becinga ukuba isezantsi intloko yempompo ye-centrifugal, incinci umthwalo wemoto. Enyanisweni, kumpompo wamanzi amdaka, xa imodeli yempompo yogutyulo inqunywe, ubungakanani bokusetyenziswa kwamandla buhambelana nokuhamba kwangempela kwempompo yogutyulo. Ukuhamba kompompo wamanzi amdaka kuya kuncipha ngokunyuka kwentloko, ngoko ke intloko ephezulu, incinci, incinci yokusetyenziswa kwamandla. Ngokuchasene noko, intloko ephantsi, ukuhamba okukhulu, ngakumbi ukusetyenziswa kwamandla. Ke ngoko, ukuze kuthintelwe ukugcwala kwemoto, ngokuqhelekileyo kufunwa ukuba eyona ntloko yokumpompa yempompo ingabi ngaphantsi kwe-60% yentloko elinganisiweyo. Ke xa intloko ephezulu isetyenziselwa ukumpompa intloko ephantsi kakhulu, imotor kulula ukuyilayisha kakhulu kunye nobushushu, ubuzaza bunokuyitshisa imotor. Kwimeko yokusetyenziswa ngokukhawuleza, kuyimfuneko ukufaka i-valve yesango yokulawula ukuphuma kwamanzi kumbhobho wokukhupha (okanye ukuvala i-outlet encinci ngamaplanga kunye nezinye izinto) ukunciphisa izinga lokuhamba kunye nokuthintela ukugqithiswa kwemoto. Nika ingqalelo ukunyuka kobushushu bemoto. Ukuba i-motor ifunyenwe ishushu, yehlisa ukuphuma kwamanzi okanye uyivale ngexesha. Eli nqaku likwalula ukungaqondi kakuhle, abanye abaqhubi bacinga ukuba ukuxhuma i-outlet yamanzi, ukunyanzelisa ukunciphisa ukuhamba, kuya kwandisa umthwalo wemoto. Enyanisweni, ngokuchaseneyo, umbhobho wokuphuma we-high-power high-power centrifugal pump drainage kunye neeyunithi zokunkcenkceshela zixhotyiswe ngeevalve zesango. Ukuze kuncitshiswe umthwalo wemoto xa iyunithi iqala, ivalve yesango kufuneka ivalwe kuqala, ize ivuleke ngokuthe ngcembe emva kokuba imoto iqale. Esi sisizathu.
