CFA yamaphepha. incazelo

CFA unqwabelana becala zisetyenziselwa ukuba bafumane imihlaba kwizakhiwo novavanyo ukulungiswa. Ebanzi ngokwaneleyo ukuyisebenzisa ngenxa yezinto eziliqela. Okokuqala, CFA imfumba ziziinkalo ezincinane efumankekayo yobugcisa izicelo. Ezi ziyakuvumela ukuba ukusebenza kumagumbi ebude - ukuya kutsho kwiimitha ezimbini, Ukuhlukunyezwa imbobo wamatye, linyanzelisa ikhonkrithi, nogunyaziso eziphathekayo ukuya omise ezimakhulu mathathu ububanzi kunye nobunzulu kweemitha mahlanu. ufakelo indawo linokuyiqhuba yokomba kwelo gumbi zibekwe ngaphandle yeyunithi yamandla.

CFA zitsho zibe ezahlukeneyo. Olunye uhlobo yokwakha zisetyenziswa izakhiwo ezitsha ukomeleza iindonga uvalo kunye neengcingo for namathambeka nkqo. Zibizwa ngokuba "ziphene iiankile." Kulo mzekelo, sebenzisa inkqubo ekhethekileyo okubambelela.

Ngokuxhomekeke kwiimeko zomhlaba wenza ukhetho nawuphi na isixhobo wokugrumba. CFA unqwabelana ukuba ubude kanye ububanzi ngokungqinelana kunye kwangaphambili umthwalo ngokuzala umthamo yezikhala okanye ankile waqonda umgudu.

Kugrunjwa kwindawo ezingazinzanga baza bankcenkceshela ngokuhlamba amaqula ikhutshwa phandle usebenzisa oluludaka okanye usebenzisa istili.

Izixhobo unqwabelana ndidikwe yenziwa usebenzisa Ukuqinisa. Ngenxa yoko, ngokungqinelana kunye nohlobo kugunyaziso umthwalo zokubambela olwenziwe yonke ubude nokuba ngaphezulu. Ubude kwicandelo kugunyaziso imiselwa ngokungqinelana ukuphakama gumbi. Nokuqiniswa ebekwe emva, phambi okanye ngexesha lovavanyo yengcinezelo equleni.

iziseko izixhobo igoqo busenza ukuba ukulungisa components imfumba egxile wequla kunye nokubonelela ububanzi eyimfuneko umaleko sokhuselo eziphathekayo. Njengoko amalungu welding, kuqinisekiswa compound isidumbu kugunyaziso ubude, ngokufanelekileyo, nefanayo amandla unyanzeliso. Aya le imfumba ubuncinane ubukhulu yentonga othambekele kweentonga. Ngokuqhelekileyo, indawo cross-wecandelo kwi kugunyaziso longitudinal ayikho ngaphantsi kwe-0.5% cross-wecandelo indawo ye imfumba ngokwayo.

Ukuze kuphuculwe iimpawu carrier mfumba, ngenxa ukugangatheka, kwenziwa crimping iindonga wequla kunye esandula wathulula eziphathekayo.

uvavanyo Pressure kungenziwa ngeendlela ezahlukeneyo.

Ngoko ke, lo umxokozelo liqulathe inxenye olongezelelweyo pump fluid ngokusebenzisa tampon leyo decompresses le wellhead, a wellhead okanye ezikhoyo umbhobho kwisiseko. Kulo mzekelo, komphetho olwenziwa noxinzelelo ka 0.2-0.3 MPA imizuzu emibini. Xa uxinzelelo ubambelele ngeli xesha akwenzeki, lo msebenzi wenziwa kwakhona emva kweyure okanye ezimbini, de afumane oko akufunayo ifunyenwe.

Kovavanyo loxinzelelo nako ukuvelisa kwi icandelo elithile le imfumba okanye ukuya ezantsi equleni ngokusebenzisa izikrufu bushing.

Imisebenzi yenziwa nokusetyenziswa kwethekhinoloji electro. Xa oku kwenziwe crimping downhole electrohydrodynamic okanye iindonga.

Enye indlela kukuba 're-ziphene ". Kulo mzekelo, udini lwenziwa kwi inxalenye ethile igoqo ngalo isitofu umphanda discontinuity ukumnika lokuqala eziphathekayo.

CFA unqwabelana zilungiswe ngokungqinelana nomjikelo inkqubo ethile eziquka imisebenzi ezininzi:

1. Kusombiwa.
2. Umbutho yesakhelo lwesamente.
3. umngxuma Ukuzaliswa of the (izohlwayo) eziphathekayo umxube.
4. Crimping umxube entsha.

Kufuneka wathi isakhelo lwesamente wavunyelwa ukuba ifakelwe nje emva kokuba kwaye phambi kokuba ugalele umngxuma ngomxube.

Kutshanje, kukho ukuphucuka lomgadi izixhobo, amanyathelo inkqubo kunye nobuchule ngokuqinisekile ezijoliswe ekuphuculeni umgangatho kunye nomthamo lokuthwala inqwaba.
