1. Ngaphambi kokumpompa, okokusebenza kufanele kuhlolwe ngokugcwele
① Ingcindezi yesistimu eyinhloko ingalungiswa ibe ngu-32MPa, ikakhulukazi kucatshangelwa ingcindezi yokumpompa okuphezulu nokuchichima kwevalvu yokuphepha eyinhloko.
② Ukususwa kwephampu kawoyela eyinhloko kuzolungiswa kube buncane, ukucindezela kwevalvu yokulandelana akufanele kube ngaphansi kuka-10.5MPa, futhi i-nitrogen eku-accumulator izokwanela.
③ Uphawu lwesilinda sikawoyela we-slide valve ngeke luvuze kwangaphakathi, isivalo sesilinda samafutha sizoba sincane ngokufanele, futhi ukuthambisa kuzokwanela futhi kube bushelelezi, ngaphandle kwalokho, inqama izophakanyiswa kancane noma ingekho ngenxa yokuphakama. i-viscosity kanye nokumelana nokhonkolo, okuzobangela ukuvuza kwangaphakathi kwe-slurry futhi kubangele ukuthi ipayipi elimise oku-Y noma isinciphisi sivinjwe.
④ Imvume yokuguga kwenqama akufanele ibe nkulu kakhulu, ngaphandle kwalokho ukwehluleka okufanayo kuzobangelwa ukuvuza kwangaphakathi kodaka.
⑤ Ipayipi elimise okuka-Y kanye negobolondo elingaphezulu kufanele livalwe ngokuqinile, ngaphandle kwalokho ipayipi lizovaleka ngenxa yokuvuza kodaka, okuzoletha ukulahlekelwa okungadingekile ekwakhiweni.
2. Izidingo zokubeka amapayipi
① Ukumpompa ibanga elide kunokumelana okukhulu, ngakho-ke ukugoba kuzoncishiswa ngesikhathi sokubeka ipayipi, futhi ukugoba okukhulu kuzosetshenziswa esikhundleni samancane.Ukuzijwayeza kufakazela ukuthi indololwane ngayinye eyengeziwe engu-90 × R1000 ilingana nokwengeza ipayipi elivundlile elingu-5m.Ngakho-ke kusetshenziswa amapayipi ama-4 kuphela φ 90 º ku-125A × R1000 indololwane, amanye angu-φ 125A × 3m ipayipi eliqondile kanye no-φ 125A × 2m ipayipi eliqondile, elinobude obuphelele obungu-310m.
② Kufanele kuqashelwe ukuqiniswa kwamapayipi kanye nokuqiniswa kwezinsimbi zamapayipi.Lolu hlobo lokupompa ibanga elide luzohlangabezana nezimo ezifana nokunyuka kokuphuma kwamapayipi, ukuqhuma kwepayipi, ukuqhuma kwe-clamp clamp, njll. Ngakho-ke, kuyadingeka ukuqinisa ngokugcwele amakhona kanye namanye amapayipi aqondile ukuze unciphise umthelela wawo.
3. Ngaphambi kokupompa, ungampompi amanzi amaningi, bese umpompa amanzi amaningi ukuze ugcobe ipayipi.
Abanye abaqhubi bangase bangaqondi ukuthi ngenxa yepayipi elide, amanzi anele kufanele afakwe ukuze agcobe ngokugcwele.Ngesikhathi sokwakha, kumpontshwa amanzi amaningi, okwaholela ekutheni indandatho yesikhumba kwezinye izinsimbi zamapayipi ilimale futhi ivuze.Lapho wenza udaka, njengoba ukuxhumana phakathi kodaka namanzi kucwiliswa emanzini isikhathi eside, amanzi azosusa udaka lukasimende, okubangela ukuhlukaniswa kodaka, okwandisa ukumelana nokupompa, okubangela ukuthi udaka lukasimende luphume eringini lesikhumba elonakele. , ngaleyo ndlela kubangele ukuxhunywa kwamapayipi.
4. Ukhonkolo kunzima ukupompa ngenxa yezinga eliphezulu kanye ne-viscosity
Kukhonkolo we-C60 wezinga eliphezulu, usayizi we-aggregate omahhadla ungaphansi kuka-30mm futhi ukugreda kunengqondo;Isilinganiso sesihlabathi 39%, isihlabathi esihle esiphakathi;Futhi ukusetshenziswa usimende kungahlangabezana nezidingo zokumpompa.Kodwa-ke, ngenxa yokuvinjelwa kwamandla, isilinganiso sikasimende samanzi siphakathi kuka-0.2 no-0.3, okuholela ekwehleni okungaba ngu-12cm, okuthinta uketshezi lukakhonkolo ngesikhathi sokupompa futhi kwandisa ukumelana.Ukwandisa isilinganiso sesihlabathi kungathuthukisa ukudonsa kwayo, kodwa kuthinta amandla futhi ayikwazi ukuhlangabezana nezidingo zokuklama nezokwakha.Ngakho-ke, indlela kuphela yokuxazulula le nkinga ukwengeza i-ejenti yokunciphisa amanzi, engeke ithinte amandla kodwa futhi yandise ukuwohloka.Asikho isinciphisi samanzi esengeziwe ekuqaleni kokupompa, ukucindezela kokumpompa kwakungu-26-28MPa, isivinini sokupompa sasihamba kancane futhi umphumela wawumpofu.Ukuzinza nokuthembeka kwepompo yekhonkrithi kuzothinteka uma ihanjiswa ngaphansi kokucindezela okukhulu isikhathi eside.Kamuva, inani elithile le-ejenti yokunciphisa amanzi (NF-2) lanezelwa, ukuwohloka kwafinyelela ku-18-20m, futhi ingcindezi yokupompa yehla kakhulu, kuphela mayelana ne-18MPa, ephindwe kabili ukusebenza kahle kokupompa.Ngaphezu kwalokho, phakathi nenqubo yokupompa, umqhubi kufanele akhunjuzwe ukuthi ukhonkolo ku-hopper kufanele kube ngaphezu komugqa ophakathi we-shaft yokuxuba, ngaphandle kwalokho kuzokwenza ukuthi ukhonkolo uhlakaze futhi ulimaze abantu, noma ipayipi izovinjelwa ngenxa. ukumunca kanye negesi.
