Menene abubuwan da ke cikin PDM Drill (Progressing Cavity Drill)?

PDM Drill wani haƙar ma'adinai ne mai ƙarfi wanda ke amfani da ruwan haƙa a matsayin wutar lantarki don canza kuzarin matsin lamba na ruwa zuwa makamashin inji.

Sassan

Injin haƙa PDM ya ƙunshi manyan kayan aiki guda huɗu: bawul mai wucewa, injin haƙa, shaft ɗin cardan, da shaft ɗin tuƙi. Injin sukurori (motar haƙa) shine babban ɓangaren haƙa.

1. Taro na Kewaya Bawul

Bawul ɗin da ke wucewa ya ƙunshi jikin bawul, hannun bawul, zuciyar bawul, da kuma bazara. A ƙarƙashin matsin lamba, zuciyar bawul ɗin tana zamewa a cikin hannun bawul, kuma motsin zuciyar bawul ɗin yana canza alkiblar kwararar ruwan - yana ba da yanayin bawul ɗin da ke wucewa yanayi biyu: wucewa da rufewa.

Yayin shiga da fita daga ramin: Ragowar da ke ratsawa ta hannun bawul da jikin bawul ba a rufe su ba, don haka bawul ɗin da ke ratsawa yana cikin yanayin wucewa, yana ba da damar laka a cikin igiyar haƙa ta wuce motar ta shiga annulus.

Lokacin da yawan kwararar laka da matsin lamba suka kai ga daidaitattun ƙimar da aka saita: Bakin bawul yana motsawa ƙasa don rufe ramin bawul ɗin wucewa. A wannan lokacin, laka tana gudana ta cikin injin, tana canza kuzarin matsin lamba zuwa makamashin injiniya.

Idan yawan kwararar laka ya yi ƙasa sosai ko kuma famfon ya tsaya: Maɓuɓɓugar ruwa tana tura tsakiyar bawul ɗin sama, kuma ramin bawul ɗin ya buɗe - yana mayar da bawul ɗin zuwa yanayin wucewa.

2. Injin Hydraulic

Motar hydraulic ta ƙunshi stator da rotor. Ana ƙera stator ɗin ta hanyar saka roba a cikin bangon ciki na bututun ƙarfe, kuma ramin ciki shine helix mai takamaiman sigogi na geometric. Rotor sandar sukurori ce mai rufin tauri. Rotor da stator ɗin suna da juna, kuma ramin helical da aka rufe yana samuwa ta hanyar bambancin da ke cikin jagororinsu zuwa cikakken canza kuzari.

Helix na rotor na mota na iya zama farawa ɗaya ko farawa da yawa:

Ƙarancin farawa na rotor yana haifar da saurin juyawa da ƙarancin juyi;

Ƙarin farawa na rotor yana haifar da ƙarancin saurin juyawa da kuma ƙarfin juyi mafi girma.

3. Shaft ɗin Cardan

Aikin shaft ɗin cardan shine canza motsi na duniyar injin zuwa juyawar axis mai tsayayye na shaft ɗin tuƙi, sannan a aika ƙarfin juyi da saurin juyawa da injin ya samar zuwa shaft ɗin tuƙi (kuma a ƙarshe zuwa ga bitin haƙa). Yawancin shaft ɗin cardan suna ɗaukar ƙirar shaft mai sassauƙa.

4. Shaft ɗin Tuƙi

Shaft ɗin tuƙi yana da alhakin watsa ƙarfin juyawa na injin zuwa ga abin haƙa ramin, yayin da yake ɗaukar nauyin axial da radial da nauyin bit ɗin (WOB) ya samar. Saboda haka, shaft ɗin tuƙi yana buƙatar tauri mai yawa, juriya ga lalacewa, da tsawon rai na aiki. A wannan yanayin, maganin kashe zafi na iya tsawaita rayuwar shaft ɗin tuƙi sosai.
