Injini Yokufuduka Ene-Downhole Positive (PDM Drill)

I-drill ye-PDM (Positive Displacement Motor) iyimoto yokudonsa ephuma emgodini ophansi esebenzisa uketshezi lokubhoboza njengamandla okuguqula amandla e-hydraulic abe amandla omshini. Lapho udaka olupompelwa yipompo yodaka lugeleza ngaphakathii-valve yokudlulaFuthi uma ingena enjinini, kwakheka umehluko othile wokucindezela phakathi kokungena kanye nokukhipha kwenjini. Lokhu kusunduza i-rotor ukuthi ijikeleze i-axis ye-stator, idlulise ijubane kanye ne-torque nge-universal joint kanye ne-drive shaft iye ku-drill bit, ngaleyo ndlela kuvumela imisebenzi yokubhoboza.

Izingxenye Eziyinhloko

I-PDM drill ihlanganisa ikakhulukazi izinhlangano ezine ezinkulu: i-bypass valve,injini yodaka, ijoyinti elijwayelekile, kanye nomgodi wokushayela.

Injini yesikulufu iyisici esiyinhloko saleli thuluzi. Ngokomkhuba kanye nokuhlaziywa kwethiyori, ukuze injini isebenze kahle, ukwehla kwengcindezi ngesigaba ngasinye senjini akufanele kudlule i-0.8 MPa. Ngaphandle kwalokho, injini ingavuza, okubangela ukwehla okusheshayo kwesivinini noma ukuma ngokuphelele, okungalimaza injini.

Umugqa owodwa wenjini uchazwa njengesigaba esisodwa. Izinga lokugeleza kodaka elisetshenziswa endaweni kufanele lihlale ngaphakathi kobubanzi obunconywayo; ngaphandle kwalokho, kuzothinta ukusebenza kahle kwenjini futhi kungandisa ukuguguleka. Amapharamitha okusebenza kwenjini yesikulufu yiwona amapharamitha okusebenza ayinhloko e-PDM drill.

I-torque yokukhipha yemoto ecatshangelwe kahle ilingana nokwehla kwengcindezi, kuyilapho ijubane lokukhipha lilingana nezinga lokugeleza kodaka olungenayo. Njengoba umthwalo ukhuphuka, ijubane lokujikeleza lethuluzi liyancipha. Ngakho-ke, ngokulawula ukufundwa kwesilinganiso sokucindezela kanye nezinga lokugeleza kwephampu ebusweni, i-torque yomgodi ophansi kanye nesivinini sokujikeleza kungalawulwa.

Isigaba Sevalvu Yokudlula

I-valve ye-bypass yakhiwe ngomzimba we-valve, i-sleeve ye-valve, i-spool ye-valve, isiphethu, nezinye izingxenye. Ngaphansi kwesenzo sokucindezela, i-spool ye-valve ishelela ngaphakathi kwe-sleeve ye-valve. Ukunyakaza kwe-spool ye-valve kushintsha indlela yokugeleza koketshezi, okungabeka i-bypass valve esimweni se-bypass noma esimweni sokuvala.

Ngesikhathi sokukhubeka nokungena, izindlela ezisesikhwameni se-valve kanye nomzimba we-valve azivaliwe, ngakho-ke i-valve ye-bypass isesimweni se-bypass. Lokhu kuvumela udaka oluvela entanjeni yokubhoboza ukuthi ludlule imoto bese lungena ku-annulus.

Uma izinga lokugeleza kodaka kanye nokucindezela kufinyelela emazingeni ajwayelekile abekwe, i-valve spool iyehla, ivale ama-valve ports. Bese udaka lugeleza ngemoto, luguqule amandla e-hydraulic abe amandla omshini.

Uma izinga lokugeleza kodaka liphansi kakhulu noma ipompo imisiwe, isiphethu sisunduza i-valve spool phezulu, sivule ama-bypass ports bese sibeka i-valve esimweni se-bypass.

Injini (Isigaba Samandla)

Injini yakhiwe yi-stator kanye ne-rotor. I-stator yakhiwa ngokufaka i-liner yerabha nge-injection ibe yipayipi lensimbi. Imbobo yayo yangaphakathi inomumo ojikelezayo onemingcele ethile yejometri. I-rotor iyinduku yesikulufu enobuso obuqinile.

I-rotor kanye ne-stator mesh zihlangana. Umehluko kuma-lead azo udala imigodi egobile evaliwe, okwenza kube lula ukuguqulwa kwamandla.

Ama-helice e-motor rotor angaba yi-single-lobe noma i-multi-lobe. Uma ama-rotor lobes emancane, isivinini siphezulu futhi i-torque iphansi; lapho ama-lobes emaningi, isivinini siphansi futhi i-torque iphakeme.

I-Universal Joint

Umsebenzi we-universal joint ukuguqula ukunyakaza kweplanethi kwemoto kube ukujikeleza okuqondile kwe-drive shaft nokudlulisa i-torque nesivinini esikhiqizwa yimoto ku-drive shaft bese kuthi kamuva ku-drill bit. Uhlobo lwe-flexible shaft lwe-universal joint luvame ukusetshenziswa.

Umgodi Wokushayela

Umsebenzi womshafti wokushayela ukudlulisa amandla okujikeleza emoto ku-drill bit ngenkathi umelana nemithwalo ye-axial kanye ne-radial ekhiqizwa yisisindo esiku-bit. Ngakho-ke, umshafti wokushayela udinga ubulukhuni obukhulu, ukumelana nokuguguleka, kanye nokuphila isikhathi eside kwenkonzo. Ukwelashwa kokushisa okucimayo kungandisa kakhulu impilo yenkonzo yomshafti wokushayela.
