Milu CFA. mafotokozedwe

milu CFA zambiri ntchito kuti apeze malo mu nyumba likufa kukonzanso. Lonse zokwanira kuwagwiritsa ntchito chifukwa zifukwa zingapo. Choyamba, milu CFA ndi miyeso ang'ono ndi mphamvu yapadera luso lapadera kwa ofunsira. machenjerero awa amakulolani ntchito mu zipinda amene kutalika - mpaka mamita awiri, kukhomerera dzenje mwa zomangamanga, analimbitsa simenti, analimbitsa simenti mpaka millimeters mazana atatu m'mimba mwake ndi akuya mamita makumi asanu. Yaying'ono unsembe amachita pobowola mu chipinda ili pa kunja kwa unit mphamvu.

milu CFA ndi zosiyanasiyana. mtundu wina wa zomangamanga ntchito nyumba yatsopano kulimbikitsa zakulera makoma ndi mipanda kwa otsetsereka choimirira. Iwo ali kutchedwa "jekeseni anangula." Pankhaniyi, ntchito dongosolo lapadera lokhazikika.

Malinga nthaka anapanga kusankha chida ena aliwonse pobowola. milu CFA ndi kutalika ndi awiri mu malinga ndi anakonzeratu katundu mwankhanza mphamvu milu kapena nangula anazindikira khama.

Tikubooleza pansi wosakhazikika ndi madzi, amasamba zitsime ikuchitika ntchito slurry kapena ntchito casing.

Zida wotopetsa milu ikuchitika ntchito zolimba. Choncho, malinga ndi chikhalidwe cha zolimba akuchita katundu ikuchitika kutalika lonse la mwina pamwamba. Kutalika kwa zolimba gawo anatsimikiza mogwirizana ndi kutalika kwa chipindacho. Zolimba anapereka pambuyo, patsogolo kapena pa mayeso mavuto bwino.

Zida mulu maziko kumapereka lingaliro akukonzekera zigawo mulu wokhudzana osati zitsime zokumba zogwiritsa ndi kupereka makulidwe kofunika wosanjikiza kuteteza konkire. Ndi zimfundo welded anaonetsetsa pawiri nyama zolimba m'litali ndi moyenera, yunifolomu mphamvu zolimba. The mizere ya mulu osachepera awiri a ndodo oyenerera ndodo. Childs, mtanda yachigawo m'dera mu zolimba kotenga si zosakwana 0.5% mtanda yachigawo Malo mulu yokha.

Kumapangitsanso makhalidwe chonyamulira mulu, chifukwa compaction, imagwiridwa crimping mpanda wa bwino ndi mwatsopano anatsanulira konkire.

Anzanu kuyezetsa zingathe kuchitika m'njira zosiyanasiyana.

Choncho, Download mukhoza kuchita gawo zina madzimadzi mpope mwa tampon amene decompresses ndi wellhead, ndi wellhead kapena alipo chitoliro m'munsi. Pankhaniyi, akamaumba ndi amachitidwa pa mavuto 0.2-0.3 MPa kwa mphindi ziwiri. Ngati kugwira kuthamanga pa nthawi izi sizotheka, ntchitoyi ikuchitika pambuyo ola limodzi kapena awiri, mpaka mukufuna analandira.

Mayeso kuthamanga angathe kubala pa gawo makamaka mulu kapena pansi bwino mwa zomangira bushing.

Ntchito akutsatiridwa ndi ntchito njira zamakono zamagetsi. Pambuyo pa zimenezi downhole electrohydrodynamic crimping kapena mpanda.

Njira ina ndi "kukonzanso jekeseni". Pankhaniyi, akamaumba ikuchitika pa malo enaake mulu mwa jekeseni mbiya discontinuity chachikulu kulowetsedwa konkire.

milu CFA imakonzedwa malinga ndi inayake ndondomeko mkombero ongokhala ntchito zingapo:

1. Pobowola.
2. Gulu la chimango anatsindika.
3. Kudzazidwa dzenje konkire pa (ndalama) kusakaniza.
4. Crimping osakaniza atsopano.

Izo ziyenera kuti chimango analimbitsa analoledwa kuikidwa kukhala ndi pambuyo ndi patsogolo nadzaza dzenje ndi osakaniza.

Posachedwapa, pali kusintha zonse zokonzekera, masitepe ndondomeko ndi njira imene mosakayikira umalimbana kuwongolera ndi mphamvu yochitira milu.
