Ungayifaka kanjani ipompo wamapayipi nokuphuma kwamapayipi?
Lapho kufakwa ipayipi lamanzi, ipayipi eliguquguqukayo kufanele libe yipayipi eliguquguqukayo eliguquguqukayo, futhi i-hose ye-heruber eguquguqukayo kufanele ixhumeke kwipayipi yepompo okudluliselwe kwi-valve, kanye ne-valve ye-value (noma i-valve) kufanele kusethwe kwipayipi lokuphuma. Umsebenzi we-Check Valve ukuvikela amanzi epayipi lokuphuma ukuthi agelezele emuva ephampu futhi aholele impeller ngemuva kokuma kwepompo. Isikimu sokufakwa kwamapayipi wamanzi kufana: Ukufakwa kwamaphampu okuzenzakalelayo kwamanzi okufakwayo kuyingxenye ebaluleke kakhulu ethinta uhla lwephampu lokuzithoba, ukufakwa akukuhle kakhulu, inani elincane kakhulu, lincane kakhulu, inani le-elbow degree lizothinta ngokuqondile amanzi wokuzivumelanisa wempompo. 1, Impompo enkulu yokuzimela ngomlomo enamanzi amancane amanzi amapayipi acabanga ukuthi lokhu kungathuthukisa inhloko yangempela yephampu ye-centrifung ye-centrifugal = inkokhelo yekhanda eliphelele ~ Ukulahleka kwekhanda. Lapho uhlobo lwephampu lunqunywa, inhloko ephelele iqinisekile; Ukulahleka kwekhanda kubalulekile ekuphikineni kwamapayipi, okuncane kakhulu kwepayipi, kukhule kakhulu ukumelana, ngakho-ke ukulahlekelwa yikhanda, ngakho-ke kunciphise ububanzi, kepha kuzokwehla, okuzokwehla, okuholela ekusebenzeni kahle kwepompo yempompo. Ngokufanayo, lapho iphamputha lamanzi elincanyana lisebenzisa ipayipi lamanzi elikhulu lisebenzisa amanzi, ngeke linciphise ikhanda langempela lepompo, kepha lizonciphisa ukulahleka kwekhanda ngenxa yokuncishiswa kwepayipi, ukuze ikhanda langempela lithuthukisiwe. Kukhona futhi imishini ecabanga ukuthi lapho ububanzi obuncane bamanzi mpompo amaphampu ngamapayipi amakhulu amanzi, izokwengeza kakhulu umthwalo wemoto. Bacabanga ukuthi ububanzi bepayipi bukhuphuka, amanzi epayipi lamanzi akhipha amanzi azosebenzisa ingcindezi enkulu emthethweni wepompo, ngakho-ke kuzokhulisa kakhulu umthwalo wemoto. Njengoba wonke umuntu azi, usayizi wengcindezi ewuketshezi uhlobene kuphela nokuphakama kwekhanda, futhi akuhlangene nosayizi wendawo yepayipi. Uma nje ikhanda liqinisekile, usayizi ongemthetho wepompo ozimele akazishintshiwe, noma ngabe ubukhulu bepayipi, ingcindezi esebenza ngokungemthetho iqinisekile. Kodwa-ke, ngokwanda kobubanzi bepayipi, ukumelana nokugeleza kuzoncishiswa, futhi izinga lokugeleza lizokwandiswa, futhi izindleko zamandla zizokwandiswa ngendlela efanele. Kepha inqobo nje uma kunesigaba sekhanda esilinganiselwe, noma ngabe unganda kanjani ububanzi bepompo bungasebenza ngokujwayelekile, futhi futhi bunganciphisa ukulahleka kwepayipi, thuthukisa ukusebenza kahle kwephampu. 2. Lapho ufaka ipayipi lokungena lamanzi okuzikhandla, izinga le-degree noma i-warping elingaphezulu lizokwenza umoya uqoqwe epayipi le-inlet, ipayipi lamanzi kanye nekhanda le-centrifugal, ukuze kukhishwe amanzi e-centrifugal. Indlela enembile yilezi: izinga lesigaba kufanele lithambekele kancane ekuqondisweni komthombo wamanzi, akufanele kube degree, ngaphezulu ukungavuthi. I-3. Uma kusetshenziswa ama-elbows amaningi epayipi lokungena kwamanzi ephampu lokuzikhandla, ukumelana kwamanzi kwendawo kuzokwandiswa. Futhi i-elbow kufanele iphenduke indlela eqonde mpo, ungavumi ukuvula ukuqondiswa kwezinga, ukuze ungaqoqi umoya. I-4, indawo yokungena yephampu yokuzikhandla ixhumeke ngqo ne-elbow, ezokwenza ukuthi amanzi agelezele nge-elbow ekusatshalalisweni okungalingani. Lapho ububanzi bepayipi bukhulu bukhulu kunendawo yokungena kwamanzi, ipayipi eliduduzayo le-eccentric kufanele lifakwe. Ingxenye ephansi ye-eccentric red ereducer kufanele ifakwe ngaphezulu, futhi ingxenye ethambekele kufanele ifakwe phansi. Ngaphandle kwalokho, ukuqoqa umoya, ukunciphisa inani lamanzi noma amanzi epompo, futhi ube nomsindo wokuphahlazeka. Uma ubukhulu bepayipi le-Inlet Inlet liyefana nelamanzi wepompo, ipayipi eliqondile kufanele lingezwe phakathi kokungena kwamanzi kanye ne-elbow. Ubude bepayipi eliqondile akufanele bube ngaphansi kwezikhathi ezi-2 kuya kwezi-3 ububanzi bepayipi lamanzi. I-5, ipompo ozimele ifakwe i-valve engezansi yepayipi elingezansi yamanzi ipayipi elilandelayo alikho mpo, njengokufakwa, i-valve ayikwazi ukuvalwa yodwa, kubangele ukuvuza kwamanzi. Indlela Eqondile Yokufaka yilena: Ifakwe i-valve engezansi yepayipi lamanzi, isigaba esilandelayo sihamba phambili mpo. Uma ukufakwa okumile kungenzeki ngenxa yezimo ze-terrain, i-angle phakathi kwe-axis yamapayipi kanye nendiza ye-degree kufanele ibe ngaphezulu kuka-60 °. I-6 . Uma kukhona i-sediment kanye nokunye ukungcola phansi echibini, isikhathi sokungena ngaphakathi kwechibi lingaphansi kwezikhathi eziyi-1.5 ububanzi, kuzodala ukuthi ukungena kwamanzi kubushelelezi lapho kuphompasa noma ukumunca udoti. . Indlela yokufaka enembile yilena: Ukujula kwamanzi okujula kwamanzi ngamanzi amancane naphakathi ngeke kube ngaphansi kwama-300 ~ 600mm, futhi ipompo enkulu yamanzi ngeke ibe ngaphansi kwama-600 ~ 1000mm7. I-outlet of reampet pump ingaphezulu kwezinga elijwayelekile lamanzi echibi lokuphuma. Uma i-Outlet of Sewge Pump ingaphezulu kwezinga elijwayelekile lamanzi echibi lokuphuma, yize ikhanda lempompo liyanda, ukugeleza kuncishisiwe. Uma indawo yokuphuma kwamanzi kufanele ibe ngaphezulu kwezinga lamanzi echibi le-outlet ngenxa yezimo zomhlaba, i-elbow nepayipi elifushane kufanele lifakwe emlonyeni wepayipi, ukuze ipayipi libe yi-siphon futhi ukuphakama kokuphuma kungancishiswa. 8 Amakhasimende amaningi ajwayele ukucabanga ukuthi ukwehla kwekhanda le-centrifugal kuyinto encane umthwalo wemoto. Eqinisweni, kwimpompo yokuthuthwa kwendle, lapho kunqunywa imodeli yepompo yendle, usayizi wokusebenzisa amandla alingana nokugeleza kwangempela kwepompo yendle. Ukugeleza kwepompo yendle kuzokwehla ngokunyuka kwekhanda, ngakho-ke phezulu ikhanda, lincane ukugeleza, kuncipha ukusetshenziswa kwamandla. Ngokuphambene nalokho, engeza ikhanda, kukhudlwana ukugeleza, kukhulisa amandla. Ngakho-ke, ukuze uvikele ukulayisha ngokweqile kwezimoto, ngokuvamile kudingeke ukuthi ikhanda lepompo yepompo akufanele ibe ngaphansi kwama-60% ekhanda elilinganisiwe. Ngakho-ke lapho ikhanda eliphakeme lisetshenziselwa ukupompa ikhanda eliphansi kakhulu, imoto kulula ukuyilayisha ngokweqile nokushisa, kungathi sína kungashisa imoto. Uma kwenzeka ukusetshenziswa kwezimo eziphuthumayo, kuyadingeka ukufaka i-valve valve yokulawula ukuphuma kwamanzi ngepayipi lokuphuma (noma ukuvimba ukuphuma okuncane ngokhuni nezinye izinto) ukunciphisa izinga lokugeleza futhi uvikele ukugcwala kwemoto. Naka ukunyuka kwezinga lokushisa kwemoto. Uma imoto itholakala ukuthi ishiswe ngokweqile, yehlisa ukuphuma kwamanzi ukugeleza noma ukuyivala ngesikhathi. Leli phuzu futhi kulula ukuqondisisa, abanye opharetha bacabanga ukuthi baxhuma indawo yokuphuma kwamanzi, baphoqa ukuncishiswa kokugeleza, kuzokwengeza umthwalo wemoto. Eqinisweni, ngokuphambene nalokho, ipayipi lokuphuma lama-portrifugal amaphampu e-centrifugal ajwayelekile namayunithi wokunisela afakwe ama-valves ama-Gate. Ukuze unciphise umthwalo wemoto lapho iyunithi iqala, i-value valve kufanele ivalwe kuqala, bese kuthi kancane kancane yavulwa ngemuva kokuthi imoto iqale. Lesi yisizathu.
