Kuchiza pamwamba pa downhole motor- njira yabwino yothetsera dzimbiri mu brine yodzaza

1. Kuthetsa bwino vuto la dzimbiri mu brine yodzaza.

Kufananiza njira yopangira:

a. Chromium plating ndiye njira yomwe imagwiritsidwa ntchito kwambiri pakadali pano. 90% ya makasitomala apakhomo a petroleum amagwiritsa ntchito njirayi, yomwe imakhala ndi moyo waufupi komanso mtengo wotsika. Vuto lalikulu la electroplating ndi kuwonongeka kwa chilengedwe, ndipo electroplating singagwire ntchito mu brine yodzaza.

b. Kupopera mbewu mankhwalawa WC, makasitomala amafuna WC ❖ kuyanika pa zipangizo kubowola, kuwonjezera mphamvu kuvala kukana, ndi kugonjetsedwa ndi hydrogen sulfide, madzi mchere ndi dzimbiri zina. Choyipa chake ndi kukwera mtengo, ndipo ubwino wake ndi moyo wautali wautumiki. Chida chobowola chakhala chikugwiritsidwa ntchito kwa maola opitilira 600 ndipo sichinasinthe, ndipo chitha kugwiritsidwa ntchito nthawi zonse mumadzi odzaza.

2. Kupaka Technology Kuthetsa Vuto la Kuwonongeka kwa Madzi a Mchere

a. Ukadaulo wokutira (amangoyambitsa njira yabwino yothetsera vuto la dzimbiri m'madzi amchere odzaza)

Mapampu amadzimadzi ali ndi malo owoneka bwino otchedwa "lobes" okhala ndi 4, 5 kapena 7 lobes pamwamba otchedwa crests (kapena crests). Ma crests amapanga "main diameter". Kukula kwakukulu kumasiyana kuchokera ku 4.0 mpaka 6.5 mainchesi, komwe kumakhala kukula kwa injini.

Malo otsikitsitsa amatchedwa mbiya (kapena mbiya), ndipo mbiya imapanga "m'mimba mwake osachepera". Mtunda wokhazikika kuchokera ku lobe kupita ku ufa ndi pafupifupi ¼-inchi (6.35mm). Pali zofunikira kwambiri za "wave top" pakati pa injini ndi "kudumpha" pakati pa mbali ziwirizo. Monga muyezo, mtengo wa "runout" uyenera kukhala wosakwana 0.010" (0.254 mm). Chilichonse chowonjezera ndi payipi ya rabara ya mpope idzawonongeka mwamsanga pamene galimoto imayenda panthawi yogwira ntchito.

Kukonzekera pamwamba

a. Popaka utoto, kuphulika kwa grit sikofunikira. Pamwamba payenera kutsukidwa ndi zida zamanja pokhapokha ngati kuli kofunikira kapena kuchotsa mafuta. Kupopera mbewu mankhwalawa kungagwiritsidwe ntchito ngati zosunga zobwezeretsera, pakafunika kuyeretsa msanga pamwamba kapena kukonza pang'ono zokutira zopopera.
