Ungawafaka kanjani amapayipi amanzi okungenisa kanye namapayipi okukhipha?
Lapho kufakwa ipayipi lokukhipha iphampu yamanzi, ipayipi lodayamitha eliguquguqukayo kufanele libe yipayipi lobubanzi obuguquguqukayo obugxilile, futhi ijoyinti lepayipi lerabha eliguquguqukayo kufanele lixhunywe esikhumulweni sepompo ukuze kuncishiswe amandla okudlidliza adluliselwe epayipini ngenxa yokudlidliza kwepompo, futhi Igeji ye-pressure gauge kufanele ifakwe epayipini elifushane ngaphambi kwevalvu, futhi i-valve yokuhlola kanye ne-valve yesango (noma i-valve yokumisa) kufanele ifakwe epayipini lokuphuma.Umsebenzi we-valve yokuhlola ukuvimbela amanzi epayipi lokuphuma ukuthi angagelezi abuyele epompo futhi abe nomthelela ku-impeller ngemva kokuma kwepompo.Uhlelo lokufaka ipayipi lokungena emanzini lufana nalokhu: ukufakwa kwepayipi lokungena lephampu lamanzi eliziqhumisayo liyingxenye ebaluleke kakhulu ethinta uhla lokudonsa lwephampu eziziqhumisayo, ukufakwa akuvuzi kahle, ipayipi lide kakhulu, liwugqinsi kakhulu, lincane kakhulu, inombolo yendololwane kanye nendololwane degree izothinta ngqo impompo self-priming amanzi suction.I-1, iphampu yomlomo omkhulu oziqhumisayo enepayipi elincane lamanzi ukuhlinzeka ngamanzi abantu abaningi bacabanga ukuthi lokhu kungathuthukisa ikhanda langempela lepompo elizibambayo, inhloko yangempela yepompo ye-centrifugal eyi-self-priming = ikhanda eliphelele ~ ukulahlekelwa kwekhanda.Lapho uhlobo lwepompo lunqunywa, ikhanda eliphelele liqinisekile;Ukulahlekelwa kwekhanda kubalulekile kusuka ekuphikisweni kwepayipi, okuncane kobubanzi bepayipi, ukumelana okukhulu, ngakho-ke ukulahlekelwa kwekhanda okukhulu, ngakho-ke ukunciphisa ububanzi, ikhanda langempela lepompo le-centrifugal alikwazi ukwanda, kodwa lizokwehla, okuholela ekwehleni kokusebenza kahle kwephampu ezizenzelayo.Ngokufanayo, lapho iphampu yamanzi enobubanzi obuncane isebenzisa ipayipi elikhulu lamanzi ukumpompa amanzi, ngeke inciphise ikhanda langempela lepompo, kodwa izonciphisa ukulahlekelwa kwekhanda ngenxa yokunciphisa ukumelana namapayipi, ukuze ikhanda langempela lithuthukiswe. .Kukhona nemishini ecabanga ukuthi lapho iphampu yamanzi e-diameter encane idonsa ngamapayipi amakhulu amanzi, izokwandisa kakhulu umthwalo wemoto.Bacabanga ukuthi ububanzi bepayipi buyanda, amanzi epayipi lokuphuma kwamanzi azofaka ingcindezi enkulu ku-pump impeller, ngakho-ke kuzokwandisa kakhulu umthwalo wemoto.Njengoba wonke umuntu azi, ubukhulu bengcindezi ye-liquid buhlobene kuphela nokuphakama kwekhanda, futhi akuhlangene nobukhulu bendawo yepayipi ye-cross-sectional.Uma nje ikhanda liqinisekile, usayizi we-impeller we-self-priming pump awushintshi, kungakhathaliseki ukuthi ubukhulu bepayipi bukhulu kangakanani, ingcindezi esebenza ku-impeller iqinisekile.Kodwa-ke, ngokunyuka kobubanzi bepayipi, ukumelana nokugeleza kuzoncishiswa, futhi izinga lokugeleza lizokwenyuka, futhi izindleko zamandla zizokwenyuka ngendlela efanele.Kodwa inqobo nje uma esigabeni sekhanda elilinganiselwe, kungakhathaliseki ukuthi ukwandisa ububanzi bepompo kungasebenza ngokujwayelekile, futhi kunganciphisa nokulahlekelwa kwepayipi, kuthuthukise ukusebenza kahle kwepompo.2. Lapho ufaka ipayipi lokungena lamanzi lepompo eliziqhumisayo, izinga ledigri noma i-warping ekhuphukayo izokwenza umoya uqoqwe epayipini elingenisayo, i-vacuum yepayipi lamanzi kanye nephampu ye-centrifugal, ukuze ikhanda lokudonsa lephampu elimaphakathi. kuncipha futhi ukuphuma kwamanzi kuncipha.Indlela enembile iwukuthi: izinga lesigaba kufanele lithambekele kancane ekuqondeni komthombo wamanzi, akufanele libe yidigri, lingabi ngaphezu kokutshekela phezulu.3. Uma kusetshenziswa izindololwane ezengeziwe epayipini lokungena lamanzi lepompo elizibambayo, ukumelana nokugeleza kwamanzi endawo kuzokwenyuka.Futhi indololwane kufanele iphendukele ohlangothini oluqondile, ungavumeli ukuphendukela ku-degree degree, ukuze ungaqoqi umoya.I-4, i-self-priming pump inlet ixhunywe ngokuqondile nendololwane, okuzokwenza amanzi ageleze ngendololwane angene ekusabalaleni okungalingani kwe-impeller.Uma ububanzi bepayipi lokungena bukhulu kunendawo yokungena yepompo yamanzi, ipayipi elincishiswayo elingenasici kufanele lifakwe.Ingxenye eyisicaba ye-eccentric reducer kufanele ifakwe phezulu, futhi ingxenye ethambekele kufanele ifakwe ngezansi.Uma kungenjalo, qoqa umoya, wehlise inani lamanzi noma umpompe amanzi, futhi ube nomsindo wokuphahlazeka.Uma ububanzi bepayipi lokungena kwamanzi bufana nelokungena kwamanzi epompo, ipayipi eliqondile kufanele lengezwe phakathi kwe-inlet yamanzi kanye nendololwane.Ubude bombhobho oqondile akufanele bube ngaphansi kuka-2 kuya ku-3 ububanzi bepayipi lamanzi.I-5, iphampu ye-self-priming ifakwe i-valve engezansi yepayipi yokungena kwamanzi isigaba esilandelayo asiqondile, njengalokhu kufakwa, i-valve ayikwazi ukuvalwa ngokwayo, okubangela ukuvuza kwamanzi.Indlela yokufaka eqondile yile: ifakwe i-valve engezansi yepayipi lokungena kwamanzi, isigaba esilandelayo singcono kakhulu mpo.Uma ukufakwa okuqondile kungenzeki ngenxa yesimo sezwe, i-engeli ephakathi kwe-axis yepayipi nendiza ye-degree kufanele ibe ngaphezu kuka-60°.6. Isikhundla sokungena sepayipi lokungena lamanzi lepompo le-self-priming akulungile.(1) Ibanga eliphakathi kwendawo yokungena yepayipi lamanzi lepompo eliziqhumisayo kanye nephansi nodonga lwepayipi lokungena amanzi lingaphansi kobubanzi bokungena.Uma kunenhlabathi nokunye ukungcola phansi echibini, isikhawu phakathi kwendawo yokungena kanye nephansi lechibi lingaphansi kobubanzi obuphindwe izikhathi ezingu-1.5, kuzodala ukuthi amanzi angenawo abushelelezi lapho upompa noma ukumunca inhlabathi kanye nemfucumfucu, ukuvimbela ukungena.(2) Uma ukujula kwepayipi lamanzi lokungena kunganele, kuzokwenza ukuthi indawo yamanzi ezungeze ipayipi lokungena amanzi ikhiqize ama-whirlpool, kuphazamise ukudonsa kwamanzi futhi kunciphise ukuphuma kwamanzi.Indlela yokufaka enembile yilena: ukujula kokungena kwamanzi kwephampu yamanzi ephakathi nendawo akumele kube ngaphansi kuka-300 ~ 600mm, futhi iphampu yamanzi enkulu akufanele ibe ngaphansi kuka-600 ~ 1000mm7.Indawo yokukhipha imfucumfucu yendle ingaphezu kwezinga elivamile lamanzi echibini lokuphuma.Uma ukuphuma kwepompo yemfucumfucu kungaphezu kwezinga elivamile lamanzi echibini lokuphuma, nakuba ikhanda lepompo lenyuka, ukugeleza kuyancipha.Uma ukuphuma kwamanzi kufanele kube ngaphezu kwezinga lamanzi echibini lokuphuma ngenxa yesimo sezwe, i-elbow kanye nepayipi elifushane kufanele kufakwe emlonyeni wepayipi, ukuze ipayipi ibe yi-siphon futhi ukuphakama kwendawo yokuphuma kungancishiswa.8. Iphampu yokukhuculula indle enekhanda eliphezulu isebenza ekhanda eliphansi.Amakhasimende amaningi ngokuvamile acabanga ukuthi uma ikhanda lepompo le-centrifugal liphansi, umthwalo wemoto uba mncane.Eqinisweni, ngepompo yokuthuthwa kwendle, lapho imodeli yepompo yokuthuthwa kwendle inqunywa, ubukhulu bokusetshenziswa kwamandla bulingana nokugeleza kwangempela kwepompo yokuthuthwa kwendle.Ukugeleza kwepompo yokuthuthwa kwendle kuzokwehla ngokunyuka kwekhanda, ngakho-ke ukuphakama kwekhanda, ukugeleza okuncane, kuncane ukusetshenziswa kwamandla.Ngokuphambene nalokho, ikhanda eliphansi, ukugeleza okukhulu, kukhulu ukusetshenziswa kwamandla.Ngakho-ke, ukuze uvimbele ukugcwala kwemoto, ngokuvamile kuyadingeka ukuthi ikhanda lokumpompa langempela lepompo akufanele libe ngaphansi kuka-60% wekhanda elilinganisiwe.Ngakho-ke lapho ikhanda eliphakeme lisetshenziselwa ukumpompa ikhanda eliphansi kakhulu, injini kulula ukuyilayisha kakhulu nokushisa, okujulile kungashisa injini.Uma kusetshenziswa izimo eziphuthumayo, kuyadingeka ukufaka i-valve yesango yokulawula ukuphuma kwamanzi epayipini lokuphuma (noma ukuvimba i-outlet encane ngokhuni nezinye izinto) ukunciphisa izinga lokugeleza nokuvimbela ukugcwala kwemoto.Naka ukukhuphuka kwezinga lokushisa kwemoto.Uma injini itholakala ishisa ngokweqile, yehlisa ukugeleza kwamanzi noma uyivale ngesikhathi.Leli phuzu libuye libe lula ukungaqondi kahle, abanye opharetha bacabanga ukuthi ukuxhuma ukuphuma kwamanzi, ukuphoqelela ukunciphisa ukugeleza, kuzokwandisa umthwalo wemoto.Eqinisweni, ngokuphambene nalokho, ipayipi eliphumayo le-high-power high-power centrifugal pump drainage kanye namayunithi okunisela afakwe ama-valve esango.Ukuze unciphise umthwalo we-motor lapho iyunithi iqala, i-valve yesango kufanele ivalwe kuqala, bese ivuleka kancane kancane ngemva kokuqala kwe-motor.Lesi yisizathu.
