Kodi zigawo za PDM Drill (Progressing Cavity Drill) ndi ziti?

PDM Drill ndi chobowolera champhamvu chosinthira madzi m'bowo lomwe limagwiritsa ntchito madzi obowolera ngati mphamvu yosinthira mphamvu yamadzimadzi kukhala mphamvu yamakina.

Zigawo

PDM Drill imakhala ndi magulu anayi akuluakulu: valavu yodutsa, mota ya hydraulic, shaft ya cardan, ndi shaft yoyendetsa. Screw motor (mota ya hydraulic) ndiye gawo lalikulu la drill.

1. Msonkhano wa Valavu Yodutsa

Valavu yodutsa imapangidwa ndi thupi la valavu, chikwama cha valavu, chikwama cha valavu, ndi kasupe. Pakapanikizika, chikwama cha valavu chimalowa mkati mwa chikwama cha valavu, ndipo kuyenda kwa chikwama cha valavu kumasintha njira yoyendera madzi—kupatsa valavu yodutsa njira ziwiri: kudutsa ndi kutseka.

Mukalowa ndi kutuluka m'bowo: Mabowo odutsa m'manja mwa valavu ndi thupi la valavu satsekedwa, kotero valavu yodutsa imakhala mu mkhalidwe wa kupingasa, zomwe zimalola matope mu chingwe chobowolera kudutsa mota ndikulowa mu annulus.

Pamene kuthamanga kwa matope ndi kuthamanga kwa madzi zifika pamlingo wokhazikika: Pakati pa valavu pamadzi ...

Ngati matope akuyenda pang'ono kwambiri kapena ngati pampu yayimitsidwa: Kasupe amakankhira pakati pa valavu mmwamba, ndipo dzenje la valavu yodutsa limatsegulidwa—kubwezeretsa valavuyo ku mkhalidwe wa kudutsa.

2. Hydraulic Motor

Mota ya hydraulic imakhala ndi stator ndi rotor. Stator imapangidwa poika bushing ya rabara mu khoma lamkati la chitoliro chachitsulo, ndipo dzenje lake lamkati ndi helix yokhala ndi magawo enaake a geometric. Rotor ndi ndodo ya screw yokhala ndi chophimba cholimba. Rotor ndi stator mesh pamodzi, ndipo helical sealed cavity imapangidwa ndi kusiyana kwa ma lead awo kuti asinthe mphamvu kwathunthu.

Helix ya injini ya rotor ikhoza kukhala yoyambira kamodzi kapena yoyambira yambiri:

Kuyamba kochepa kwa rotor kumapangitsa kuti liwiro lozungulira likhale lalikulu komanso kuti mphamvu yake ikhale yotsika;

Kuyamba kwambiri kwa rotor kumapangitsa kuti liwiro lozungulira likhale lotsika komanso kuti mphamvu ikhale yokwera.

3. Katani Road

Ntchito ya shaft ya cardan ndikusintha kayendedwe ka mapulaneti a mota kukhala kuzungulira kokhazikika kwa shaft yoyendetsa, ndikutumiza torque ndi liwiro lozungulira lopangidwa ndi mota kupita ku shaft yoyendetsa (ndipo pamapeto pake ku drill bit). Ma shaft ambiri a cardan amagwiritsa ntchito kapangidwe ka shaft kosinthasintha.

4. Shaft Yoyendetsa

Shaft yoyendetsa galimotoyo ili ndi udindo wotumiza mphamvu yozungulira ya mota kupita ku drill bit, pomwe imanyamula katundu wa axial ndi radial wopangidwa ndi kulemera kwa bit (WOB). Chifukwa chake, shaft yoyendetsa galimotoyo imafuna kuuma kwambiri, kukana kuwonongeka, komanso moyo wautali wautumiki. Pankhaniyi, kuletsa kutentha kumatha kukulitsa kwambiri moyo wautumiki wa shaft yoyendetsa.
