1. Usati wapomba, midziyo ichaongororwa zvizere
① Iyo huru sisitimu yekumanikidza inogona kugadziridzwa kusvika 32MPa, kunyanya tichifunga nezve yakakwira yekupomba kumanikidza uye kufashukira kwevhavha huru yekuchengetedza.
② Kutamiswa kwepombi huru yemafuta kuchagadziridzwa kusvika padiki, kudzvanywa kwevhavha yekutevedzana hakuzove kwakaderera pane 10.5MPa, uye nitrogen mu accumulator ichave yakakwana.
③ Chisimbiso chesiraidhi chevharuvha yemafuta cylinder ichave isina kubuda mukati, iyo buffer yehumburumbira yeoiri ichave idiki zvakaringana, uye mafuta anozokwana uye akatsetseka, zvikasadaro, gondohwe richasimudzwa zvishoma nezvishoma kana kwete panzvimbo nekuda kwekukwirira. viscosity uye kuramba kwekongiri, izvo zvinokonzeresa mukati slurry kuvuza uye kuita kuti iyo Y-yakaita sepombi kana chinoderedza kuvharika.
④ Kubvumidzwa kwekupfeka kwegondohwe hakuzove kwakakurisa, zvikasadaro kutadza kumwe chete kunokonzereswa nekudonha kwemukati slurry.
⑤ Iyo pombi yakaita Y uye goko repamusoro rinofanira kunge rakavharwa zvakasimba, zvikasadaro pombi ichavharika nekuda kwekudonha kwemvura, izvo zvinounza kurasikirwa kusingakoshi pakuvaka.
2. Zvinodiwa pakuisa pombi
① Kupomba kureba kwakakura kunopesana, saka mabhendeti achaderedzwa panguva yekuiswa kwepombi, uye mabhende makuru achashandiswa pachinzvimbo chediki.Kudzidzira kunoratidza kuti yega yega 90 º × R1000 gokora yakaenzana nekuwedzera 5m yakachinjika pombi.Saka mapaipi mana chete anoshandiswa φ 90 º pa125A × R1000 gokora, mamwe φ 125A × 3m pombi yakatwasuka uye φ 125A × 2m pombi yakatwasuka, ine hurefu hwakazara hwe310m.
② Kuchenjerera kuchabhadharwa pakusimbiswa kwepombi uye kusungirirwa kwepombi dzinosungirirwa.Rudzi urwu rwekupomba rurefu ruchasangana nezviitiko zvakadai sekuwedzera kwepombi runout, kuputika kwepombi, kuputika kwepombi clamp, etc. Nokudaro, zvakakosha kusimbisa zvakakwana makona uye mamwe mapaipi akatwasuka kuti kuderedze maitiro avo.
3. Usati wapomba, usapombe mvura yakawandisa, uye pomba huwandu hwemvura hwakakodzera kuti uise pombi.
Vamwe vashandisi vanogona kusanzwisisa kuti nekuda kwepombi refu, mvura yakakwana inofanira kuwedzerwa kuti inyatsokuzora.Panguva yekuvaka, mvura yakawandisa yakapombwa, zvichikonzera kuti mhete yeganda pane dzimwe pombi dzepombi kukuvara uye kubuda.Paunenge uchigadzira dhaka, sekubatana pakati pedhaka nemvura inonyudzwa mumvura kwenguva yakareba, mvura ichabvisa simende slurry, zvichiita kuti dhaka kupatsanurwa, kuwedzera kupikisa kwepombi, zvichiita kuti simiti slurry ibude kubva kune yakakanganiswa yeganda mhete. , nokudaro zvichikonzera kuvharwa kwepombi.
4. Kongiri yakaoma kupomba nekuda kwegiredhi rayo repamusoro uye viscosity
Kune C60 yakakwirira-giredhi kongiri, iyo coarse aggregate saizi isingasviki 30mm uye giredhi inonzwisisika;Jecha reshiyo 39%, jecha riri pakati nepakati;Uye kushandiswa kwesimende kunogona kusangana nezvinodiwa zvekupomba.Zvisinei, nekuda kwekudziviswa kwesimba, chiyero chesimende chemvura chiri pakati pe 0.2 ne 0.3, zvichiita kuti pave nekuderera kweanenge 12cm, iyo inokanganisa fluidity yekrete panguva yekupomba uye inowedzera kuramba.Kuwedzera jecha reshiyo kunogona kuvandudza pumpability ayo, asi zvinokanganisa simba uye haigoni kusangana dhizaini uye kuvaka zvinodiwa.Nokudaro, nzira chete yekugadzirisa dambudziko iri ndeyekuwedzera mvura inoderedza mumiririri, iyo isingazokanganisa simba asiwo kuwedzera kuderera.Hapana mvura inoderedza mvura yakawedzerwa pakutanga kwekupomba, mhepo yekupomba yaiva 26-28MPa, kukurumidza kwepombi kwainonoka uye mhedzisiro yacho yakanga isina kunaka.Kugadzikana uye kuvimbika kwepombi yekrete ichakanganiswa kana ichitakurwa pasi pekumanikidzwa kwakanyanya kwenguva yakareba.Gare gare, imwe chiyero chemvura inoderedza agent (NF-2) yakawedzerwa, iyo inodonha yakasvika 18-20m, uye kupomba kwemhepo kwakaderera zvakanyanya, chete nezve 18MPa, iyo yakawedzera kaviri kugona kwepombi.Uye zvakare, panguva yekupomba, mushandisi anofanirawo kuyeuchidzwa kuti kongiri iri muhopi inofanirwa kunge iri pamusoro pepakati peiyo shaft yekusanganisa, zvikasadaro zvinokonzeresa kuti kongiri iparadze nekukuvadza vanhu, kana pombi ichavharika nekuda. kusveta uye gasi.
