1. Izidingo zamapayipi zokudonsa kanye nokukhipha amapayipi

1-1. Wonke amapayipi axhumene nephampu (ukuhlolwa kokuqhuma kwepayipi) kufanele abe nezisekelo ezizimele neziqinile ukuze kuncishiswe ukudlidliza kwepayipi futhi kuvinjwe isisindo sepayipi ukuthi singacindezeli iphampu.

1-2. Abakaki abalungisekayo kufanele bafakwe emapayipini angenayo naphumayo epompo. Emapayipini anokunyakaza, abakaki abamanzi kufanele bafakwe ukuze kulungiswe kahle indawo yepayipi futhi kuncishiswe amandla engeziwe kubhobho lepompo elibangelwa amaphutha okufaka.

1-3. Lapho ipayipi elixhuma iphampu nezinto zokusebenza limfushane futhi kokubili kungekho esisekelweni esifanayo, ipayipi elixhumayo kufanele liguquguquke, noma kufanele kwengezwe ipayipi lensimbi ukuze kunxeshezelwe ukungalingani kwesisekelo.

1-4. Ububanzi bokudonsa nokukhipha amapayipi akufanele kube kuncane kunobubanzi bokungena kwepompo kanye nobubanzi bokuphuma.

1-5. Ipayipi lokudonsa lephampu kufanele lihlangabezane nenethi yokumunca ikhanda (NPSH) elidingwa iphampu, futhi ipayipi kufanele libe lifushane ngangokunokwenzeka ngokujika okumbalwa. Uma ubude bepayipi budlula ibanga phakathi kwesisetshenziswa nephampu, sicela ubuze uhlelo lwenqubo ukuze lubale.

1-6. Ukuze uvimbele i-cavitation yepompo yokumunca kabili, ukuphakama kwepayipi le-nozzle ye-inlet kusuka kumshini ukuya epompo kufanele kwehliswe kancane kancane, futhi akufanele kube nokubunjwa kuka-U naphakathi nendawo! Uma kungenakugwema, i-valve yokopha kufanele yengezwe endaweni ephakeme, futhi i-valve yokudonsa kufanele yengezwe endaweni ephansi.

1-7. Ubude besigaba sepayipi eliqondile ngaphambi kokungena kwephampu yephampu eyi-centrifugal akumele kube ngaphansi kuka-3D wobubanzi bokungenisa.

1-8. Kumaphampu adonsa kabili, ukuze ugweme i-cavitation ebangelwa ukumunca okungalingani kuzo zombili izinkomba, amapayipi adonsa kabili kufanele ahlelwe ngokulinganayo ukuze kuqinisekiswe ukugeleza nokusatshalaliswa kwezinhlangothi zombili.

1-9 Ukuhlelwa kwepayipi ekugcineni kwephampu kanye nasekupheleni kwephampu ehambisanayo akufanele kuvimbe ukuqaqa nokugcinwa kwepiston ne-tie rod.

2. Ukumiswa Kwepayipi Elisizayo kweSplit Case Pump

2-1. Ipayipi lephampu elifudumele: Uma izinga lokushisa lempahla elethwa yiphampu eyicentrifugal lingaphezu kuka-200 °C, kudingeka kufakwe ipayipi lephampu elifudumele ukuze inani elincane lempahla liholwe lisuka epayipini lokulahla lephampu elisebenzayo liye endaweni yokuphuma. iphampu yokulinda, bese igeleza ngepompo yokulinda, bese ibuyela endaweni yokungena yepompo ukuze kwenziwe iphampu yokulinda Iphampu ikwi-standby eshisayo ukuze iqale kalula.

2-2. Amapayipi avimbela ukufingqa: I-DN20 25 amapayipi avimbela ukubanda kufanele afakwe kumaphampu ane-condensable medium at izinga lokushisa elivamile, futhi indlela yokumisa iyafana neyamapayipi epompo afudumele.

2-3. Ipayipi lebhalansi: Uma okuphakathi kuthambekele ekufakweni kwegesi endaweni yokungena yepompo, ipayipi lebhalansi elingabuyela esikhaleni sesigaba segesi sezinto ezisetshenziswayo ezikhuphuka nomfudlana ohlangothini lokumunca lingafakwa phakathi kombhobho wokungenisa iphampu kanye nevalve yokuvala inkethi yepompo. , ukuze igesi elakhiwe likwazi ukugeleza libuyele emuva. Ukuze ugweme i-cavitation yepompo, i-valve yokusika kufanele ifakwe kwipayipi yebhalansi.

2-4. Ipayipi elincane elibuyayo: Ukuze kuvinjwe iphampu eyi-centrifugal ukuthi isebenze ngaphansi kwezinga lokugeleza elincane lepompo, ipayipi elincane elibuyiswayo lepompo kufanele lisethwe ukubuyisela ingxenye yoketshezi olusuka endaweni yokukhipha iphampu iye esitsheni lapho kuhlukana khona. Imbobo yokudonsa iphampu ukuze kuqinisekiswe izinga lokugeleza kwepompo.

Ngenxa yemininingwane yephampu, kuyadingeka ukuba nokuqonda okuphelele kokusebenza kwepompo kanye nezinto zenqubo ezisebenza empompini, futhi ukumiswa okunengqondo kwamapayipi ayo okungenisa nokuphuma kuyadingeka ukuze kuqinisekiswe ukusebenza kwawo okuphephile nokuzinzile. .
