Chitsogozo Chokwanira cha PDC Nozzle Mitundu ndi Ntchito

M'magawo monga kubowola mafuta ndi kufufuza kwa geological, ma nozzles a PDC (Polycrystalline Diamond Compact) akhala zinthu zofunika kwambiri zowonetsetsa kuti kubowola bwino komanso mtundu wake, chifukwa cha kukana kwawo kuvala bwino, kukana kutentha kwambiri, komanso kukana kwamphamvu. Amazindikira ntchito monga kuthyola miyala, kuyeretsa miyala, ndi kuzizira pang'ono pobowola kudzera mumadzimadzi a jet. Mitundu yosiyanasiyana ya nozzles ya PDC ndi yoyenera pazikhalidwe zosiyanasiyana zogwirira ntchito. Tsatanetsatane wa magulu awo ndi ntchito zofananira.

1. Gulu mwa Mapangidwe Apangidwe

PDC nozzles makamaka anawagawa mitundu itatu kutengera kapangidwe kamangidwe: mwachindunji-jekeseni mtundu, mtundu swirling, ndi mtundu wosakanizidwa.

Direct-jekeseni PDC nozzles: Tengani kanjira kanjira kowongoka. Kuthamanga kwa ndege kumakhazikika ndi mphamvu yamphamvu, yomwe imatha kuswa mwamsanga mapangidwe a miyala yolimba. Amagwiritsidwa ntchito kwambiri pobowola miyala yolimba m'zitsime zakuya ndi zitsime zozama kwambiri, kuwongolera bwino kuswa miyala komanso kuchepetsa kuvala koboola.

Swirling PDC nozzles: Wokhala ndi mawonekedwe ozungulira oyenda mkati. Madzi akabayidwa, gawo lozungulira lozungulira limapangidwa, zomwe sizimangowonjezera luso loyeretsa la miyala pansi pa chitsime komanso kumachepetsa kusinthasintha kwapansi. Ndioyenera pobowola m'mapangidwe omwe amatha kugwa mosavuta kapena m'mipangidwe yokhala ndi mchenga wambiri, kulepheretsa kuti miyala yodulidwa zisawunjike ndikusokoneza kupita patsogolo.

Milomo ya Hybrid PDC: Phatikizani ubwino wa mitundu iwiri yomwe ili pamwambayi, ndi mphamvu zonse za jakisoni wolunjika komanso kuyeretsa kozungulira. Amagwira ntchito zodziwika bwino pakubowola m'njira zovuta, monga kubowola chitsime chopingasa pakukula kwa gasi wa shale. Amatha kulinganiza zosowa za kuswa miyala ndi kuyeretsa miyala, ndikuwongolera kukhazikika kwa kubowola.

2. Gulu ndi Ntchito Yogwira Ntchito

Malinga ndi magwiridwe antchito, ma nozzles a PDC atha kugawidwa m'malo othyola miyala, kuyeretsa miyala, ndi kuziziritsa.

Milomo ya PDC yothyoka miyala: Nthawi zambiri imapangidwa ndi mawonekedwe akulu komanso kuthamanga kwambiri. Amathyola miyala yopangidwa ndi mphamvu yamadzimadzi ndipo ndi yoyenera kubowola mwala wolimba ndi wandiweyani.

Miphuno ya PDC yotsuka miyala: Yang'anani kwambiri pakuwongolera kugawa kwamunda kuti muwonetsetse kuti zidutswa za miyala zimatumizidwa pansi munthawi yake. Amagwiritsidwa ntchito kwambiri m'mapangidwe ofewa kapena zigawo zachitsime zomwe zimatha kukulitsa.

Milomo ya PDC yozizirira: Kupyolera mu kapangidwe kake kanjira koyenera, amapereka madzi ozizira bwino pamalo ogwirira ntchito pobowola, kuchepetsa kutentha kwa ntchito ya PDC compact ndikutalikitsa moyo wautumiki wa pobowola. Amagwiritsidwa ntchito kwambiri m'zitsime zakuya zotentha kwambiri kapena pobowola nthawi yayitali.

3. Kugawikana ndi Nkhani

Kuphatikiza apo, kutengera kusiyanasiyana kwazinthu, ma nozzles a PDC amatha kugawidwa m'mitundu iwiri:zinthu zoyera za PDC ndi zopangidwa ndi PDC ndi simenti carbide.

Pure PDC zakuthupi nozzles:Khalani ndi kuuma kwambiri komanso kukana kuvala koyenera, koyenera malo obowola ovuta kwambiri.

Ma Nozzles a Composite:Ngakhale kuwonetsetsa kukana kuvala, amachepetsa ndalama zopangira ndipo ndi oyenera pobowola ntchito wamba.

Pochita ntchito, ndikofunikira kusankha bwino mtundu wa nozzle ya PDC kutengera zinthu monga kuya kwa kubowola, kulimba kwa mapangidwe, ndi mtundu wamadzimadzi kuti muwonjezere bwino pobowola ndikuwonjezera ndalama. Pamene kufufuza ndi chitukuko cha mafuta chikupita kuzinthu zozama komanso zovuta kwambiri, mapangidwe a PDC nozzles amakhala opangidwa nthawi zonse. M'tsogolomu, adzakula m'njira yoti azikhala osamva kuvala, ogwira ntchito bwino, komanso oyenerera malo ambiri ogwira ntchito, kupereka chithandizo champhamvu chaukadaulo pakukula kwamafuta ndi gasi.
