Mtunda wopopa wa konkire wapamwamba nthawi zonse umakhala wosakwanira.Kodi tiyenera kuchita chiyani?

1. Musanapope, zidazo ziyenera kuyang'aniridwa bwino
① Kuthamanga kwakukulu kwa dongosolo kungasinthidwe kukhala 32MPa, makamaka poganizira za kuthamanga kwapamwamba komanso kusefukira kwa valve yaikulu yotetezera.
② Kusamuka kwa pampu yayikulu yamafuta kudzasinthidwa kukhala osachepera, kupanikizika kwa valve yotsatizana sikuyenera kukhala kotsika kuposa 10.5MPa, ndipo nayitrogeni mu accumulator idzakhala yokwanira.
③ Chisindikizo cha slide valve silinda yamafuta sichikhala chotayira mkati, chotchinga cha silinda yamafuta chizikhala chaching'ono, ndipo mafutawo azikhala okwanira komanso osalala, apo ayi, nkhosayo imakwezedwa pang'onopang'ono kapena ayi chifukwa chapamwamba. kukhuthala ndi kukana konkriti, zomwe zingayambitse kutayikira kwamkati ndikupangitsa chitoliro chooneka ngati Y kapena chochepetsera kutsekedwa.
④ Kuloledwa kwa nkhosa yamphongo sikuyenera kukhala kwakukulu, apo ayi kulephera komweku kudzabwera chifukwa cha kutayikira kwamkati.
⑤ Chitoliro chofanana ndi Y ndi chigoba chapamwamba chiyenera kutsekedwa mwamphamvu, apo ayi chitolirocho chidzatsekedwa chifukwa cha kutayikira kwa slurry, zomwe zingabweretse kutaya kosafunikira pakumanga.
2. Zofunikira pakuyika chitoliro
① Kupopera kwamtunda wautali kumakhala ndi kukana kwakukulu, kotero kupindika kumachepetsedwa pakuyika kwa chitoliro, ndipo mipiringidzo yayikulu iyenera kugwiritsidwa ntchito m'malo mwa yaying'ono.Kuyeserera kumatsimikizira kuti 90 × R1000 chigongono chilichonse chowonjezera ndi chofanana ndi kuwonjezera chitoliro chopingasa cha 5m.Choncho mapaipi 4 okha amagwiritsidwa ntchito φ 90 º kwa 125A × R1000 chigongono, ena φ 125A × 3m chitoliro chowongoka ndi φ 125A × 2m chitoliro chowongoka, chokhala ndi kutalika kwa 310m.
② Chidwi chidzaperekedwa pakulimbitsa mipope ndi kumangirira kwa zitoliro.Kupopa kotereku kwakutali kudzakumana ndi zochitika monga kuchuluka kwa chitoliro, kuphulika kwa chitoliro, kuphulika kwa chitoliro, ndi zina zotero.
3. Musanapope, musapope madzi ochulukirapo, ndipo mpopeni madzi okwanira kuti muzipaka payipi.
Ogwiritsa ntchito ena sangamvetse kuti chifukwa cha chitoliro chachitali, madzi okwanira ayenera kuwonjezeredwa kuti azipaka mafuta.Pa nthawi yomangayo, madzi ochuluka amapopa, zomwe zinachititsa kuti mphete yapakhungu ya mapaipi ena iwonongeke ndikutuluka.Popanga matope, momwe mawonekedwe pakati pa matope ndi madzi amamizidwa m'madzi kwa nthawi yayitali, madziwo amachotsa matope a simenti, kuchititsa tsankho lamatope, kukulitsa kukana kupopera, kupangitsa kuti simenti slurry ifinyidwe kuchokera ku mphete yowonongeka yachikopa. , motero kumayambitsa kutsekeka kwa chitoliro.
4. Konkire ndizovuta kupopera chifukwa chapamwamba kwambiri komanso kukhuthala kwake
Kwa konkire yapamwamba ya C60, kukula kwake kwakukulu ndi kochepera 30mm ndipo kuyika kwake ndikoyenera;Mchenga chiŵerengero 39%, sing'anga yabwino mchenga;Ndipo kugwiritsa ntchito simenti kumatha kukwaniritsa zofunikira zopopera.Komabe, chifukwa cha kuletsa mphamvu, chiŵerengero cha simenti ya madzi chiri pakati pa 0,2 ndi 0.3, zomwe zimapangitsa kuti pakhale kutsika kwa pafupifupi 12cm, zomwe zimakhudza madzi a konkire panthawi yopopera ndikuwonjezera kukana.Kuwonjezeka kwa mchenga kungathe kupititsa patsogolo mphamvu yake, koma kumakhudza mphamvu ndipo sikungathe kukwaniritsa zofunikira za mapangidwe ndi zomangamanga.Choncho, njira yokhayo yothetsera vutoli ndikuwonjezera madzi ochepetsera, zomwe sizingakhudze mphamvu komanso kuonjezera kutsika.Palibe chotsitsa madzi chomwe chinawonjezeredwa kumayambiriro kwa kupopera, kuthamanga kwa kupopera kunali 26-28MPa, kuthamanga kwapope kunali kochedwa ndipo zotsatira zake zinali zoipa.Kukhazikika ndi kudalirika kwa pampu ya konkire kudzakhudzidwa ngati ikunyamulidwa pansi pa kupanikizika kwakukulu kwa nthawi yaitali.Pambuyo pake, kuchuluka kwa madzi ochepetsera (NF-2) kunawonjezeredwa, kutsikako kunafika ku 18-20m, ndipo kuthamanga kwapope kunachepa kwambiri, pafupifupi 18MPa yokha, yomwe inachulukitsa kawiri mphamvu yopopera.Kuphatikiza apo, panthawi yopopera, wogwiritsa ntchitoyo ayeneranso kukumbutsidwa kuti konkire yomwe ili mu hopper iyenera kukhala pamwamba pa mzere wapakati wa shaft yosakaniza, apo ayi izi zipangitsa kuti konkire iwonongeke ndikuvulaza anthu, kapena chitolirocho chidzatsekedwa chifukwa. kuyamwa ndi gasi.
