1. Ngaphambi kokupompa, izixhobo ziya kuhlolwa ngokupheleleyo
① Uxinzelelo lwenkqubo oluphambili lunokulungelelaniswa kwi-32MPa, ngokukodwa ngokuqwalasela uxinzelelo oluphezulu lokumpompa kunye nokuphuphuma kwevalve yokhuseleko oluphambili.
② Ukufuduswa kwempompo ye-oyile enkulu kuya kulungelelaniswa kuncinci, uxinzelelo lwevalve yokulandelelana aluyi kuba ngaphantsi kwe-10.5MPa, kwaye i-nitrogen kwi-accumulator iya kwanela.
③ Itywina le-oyile yesilayidi yesilayidi iya kukhululeka ekuvuzeni kwangaphakathi, isithinteli sesilinda seoli siya kuba sincinci ngokufanelekileyo, kwaye ukuthambisa kuyakwanela kwaye kugudiswe, kungenjalo, inkunzi yegusha iya kunyuswa ngokucothayo okanye hayi endaweni ngenxa yokuphakama okuphezulu. i-viscosity kunye nokuchasana kwekhonkrithi, okuya kubangela ukuvuza kwangaphakathi kwe-slurry kwaye kubangele ukuba umbhobho owenziwe ngu-Y okanye umnciphisi uvalwe.
④ Ukukhutshwa kwenkunzi yegusha akusayi kuba kukhulu kakhulu, kungenjalo ukusilela okufanayo kuya kubangwa kukuvuza kwangaphakathi kodaka.
⑤ Umbhobho omile okwe-Y kunye neqokobhe elingaphezulu kufuneka livalwe ngokuqinileyo, kungenjalo umbhobho uya kuvaleka ngenxa yokuvuza kodaka, okuya kuzisa ilahleko engeyomfuneko kulwakhiwo.
2. Iimfuno zokubeka umbhobho
① Ukumpompa umgama omde kunokumelana okukhulu, ngoko ukugoba kuya kuncitshiswa ngexesha lokubeka umbhobho, kwaye ukugoba okukhulu kuya kusetyenziswa endaweni encinci.Ukuziqhelanisa kubonisa ukuba ingqiniba nganye eyongeziweyo engama-90 × i-R1000 ilingana nokongeza i-5m yombhobho oxwesileyo.Ngoko ke kusetyenziswa imibhobho emi-4 kuphela φ 90 º kwi-125A × i-R1000 engqinibeni, abanye φ 125A × 3m umbhobho othe ngqo kunye no-φ 125A × 2m umbhobho othe ngqo, nobude bubonke be-310m.
② Ingqalelo iya kuhlawulwa ekomelezeni imibhobho kunye nokuqinisa izibophelelo zemibhobho.Olu hlobo lokumpompa umgama omde luya kuhlangabezana neziganeko ezifana nokunyuka kokuphuma kombhobho, ukugqabhuka kombhobho, ukugqabhuka kombhobho obambezelayo, njl.
3. Phambi kokumpompa, musa ukumpompa amanzi amaninzi, kwaye umpompe umlinganiselo ofanelekileyo wamanzi ukuthambisa umbhobho.
Abanye abaqhubi banokungaqondi ukuba ngenxa yombhobho omde, amanzi aneleyo kufuneka afakwe ukuze agcobe ngokupheleleyo.Ngexesha lokwakha, amanzi amaninzi aye ampontshwa, nto leyo eyabangela ukuba iringi yesikhumba kwezinye izibambiso zemibhobho yonakaliswe kwaye ivuze.Xa usenza udaka, njengoko ujongano phakathi kodaka kunye namanzi luntywiliselwa emanzini ixesha elide, amanzi aya kuthabatha uludaka lwesamente, ebangela ulwahlulo lodaka, ukwandisa ukuxhathisa ukumpompa, okubangela ukuba udaka lwesamente lucudise ngaphandle kweringi yesikhumba eyonakalisiweyo. , ngaloo ndlela ibangela ukufakwa kombhobho.
4. Ikhonkrithi inzima ukupompa ngenxa yezinga eliphezulu kunye ne-viscosity
Kwi-concrete ye-C60 ephezulu, ubukhulu be-coarse aggregate bungaphantsi kwe-30mm kwaye ukulinganisa kunengqiqo;Umlinganiselo wesanti ngama-39%, isanti ephakathi;Kwaye ukusetyenziswa kwesamente kunokuhlangabezana neemfuno zokupompa.Nangona kunjalo, ngenxa yokuthintelwa kwamandla, umlinganiselo we-samente wamanzi uphakathi kwe-0.2 kunye ne-0.3, okukhokelela ekuhlahleni malunga ne-12cm, echaphazela umbane wekhonkrithi ngexesha lokupompa kunye nokwandisa ukuchasana.Ukwandisa umlinganiselo wesanti kunokuphucula ukumpompa kwayo, kodwa kuchaphazela amandla kwaye ayikwazi ukuhlangabezana neemfuno zoyilo kunye nokwakhiwa.Ngoko ke, indlela yodwa yokusombulula le ngxaki kukongeza i-ejenti yokunciphisa amanzi, engayi kuchaphazela amandla kodwa ikhulise i-slump.Akukho mnciphisi wamanzi wongezwa ekuqaleni kokupompa, uxinzelelo lokupompa lwaluyi-26-28MPa, isantya sokupompa sasicotha kwaye umphumo wawubi.Ukuzinza kunye nokuthembeka kwempompo yekhonkrithi kuya kuchaphazeleka ukuba ihanjiswa phantsi koxinzelelo oluphezulu ixesha elide.Kamva, inani elithile le-agent yokunciphisa amanzi (NF-2) yongezwa, i-slump yafika kwi-18-20m, kwaye uxinzelelo lokupompa lwehla kakhulu, kuphela malunga ne-18MPa, ephindwe kabini ukupompa ngokufanelekileyo.Ukongezelela, ngexesha lenkqubo yokumpompa, umqhubi kufuneka akhunjuzwe kwakhona ukuba ikhonkrithi kwi-hopper kufuneka ibe ngaphezu kwendawo ephakathi ye-shaft yokuxuba, ngaphandle koko kuya kubangela ukuba ikhonkrithi itshize kwaye ibuhlungu abantu, okanye umbhobho uya kuvinjelwa ngenxa. ukufunxa kunye negesi.
