Zida Zogwirira Ntchito | Kalasi Yobowolera-Yopera-Yopera | Mota Yosamutsa Yabwino

1. Mapulogalamu

Pogwiritsa ntchito mphamvu ya hydraulic, PDM imayendetsa gulu la kubowola pansi mozungulira, zomwe zimathandiza ntchito monga kubowola, kugaya, ndi kusokoneza.

2. Kapangidwe kake

PDM makamaka imakhala ndi gawo lapamwamba,valavu yodutsa, stator, rotor, coupling, water passage sub, bearing assembly, drive shaft, ndi bottom sub.

3. Mfundo Yogwirira Ntchito

PDM imasintha mphamvu ya madzi othamanga kwambiri kukhala mphamvu yamakina kudzera mu kulumikizana kwa rotor ndi stator. Madzi othamanga kwambiri amalowa m'zipinda zotsekedwa zomwe zimapangidwa pakati pa rotor ndi stator. Kusiyana kwa kuthamanga kumapangitsa kuti rotor izungulire mozungulira njira yozungulira ya stator. Rotor imazungulira mozungulira mzere wa stator, pomwe nthawi yomweyo imazungulira mozungulira mzere wake, ndikuyendetsa kuzungulira kwa drill bit.

4. Mafotokozedwe Aukadaulo

Muyezo wogwiritsidwa ntchito: SY/T 5383 Positive Displacement Motor

Chitsanzo chofotokozera

zitsanzo:

• 9LZ95×7.0 : M'mimba mwake wakunja 95 mm, mota ya hydraulic ya 9/10 lobe ratio, bit nozzle pressure drop 7 MPa.
• 5LZ165×7.0Ⅱ : M'mimba mwake wakunja 165 mm, mota ya hydraulic ya 5/6 lobe ratio, bit nozzle pressure drop 7.0 MPa, kusintha kwa kapangidwe kake ka PDM yowongoka.
• 5LZ197×7.0-SWFG: Chimake chakunja cha 197 mm, mota ya hydraulic ya 5/6 lobe ratio, nyumba yopindika kawiri yokhala ndi stabilizer, rotor yopanda kanthu yokhala ndi flow diversion, kutentha kwakukulu kogwirira ntchito 150°C, bit nozzle pressure drop 7.0 MPa.

5. Njira Yogwirira Ntchito

(1) Kusonkhanitsa BHA.

(2) Thamangani pang'onopang'ono mpaka mamita 3-5 kuchokera pa kuya kwa malo omwe mukufuna, yambani kupopa madzi kuti azizungulira ndikutsuka chitsime. Kuthamanga kwa 30 m/mphindi kumalimbikitsidwa. Dzazani chingwe chobowolera ndi madzi oyera ozungulira 500 m iliyonse mukalowa.

(3) Kuchepetsa pang'onopang'ono, kenako yambani kuboola. Kulemera pa bit (WOB): 5–15 kN. Kuthamanga kwa madzi: 500–600 L/min.

(4) Tulutsani m'bowo (POOH).

6. Malangizo Opewera

(1) Onetsetsani kuti pamwamba pa PDM pakhazikika bwino panthawi yoyesa pamwamba.

(2) Madzi ozungulira magazi ayenera kukhala oyera.

(3) Madzi obwerera ayenera kufufuzidwa ndi kuchotsedwa.

(4) Mutu wa chitsime uyenera kukhala ndi chipangizo chodzitsekera kuti zinthu zazing'ono zisagwere m'chitsimemo.

(5) Tsukani bwino chitsime musanasinthe chimbudzi chimodzi komanso mukamaliza kuboola.

7. Kukonza ndi Kusunga

(1) Mukamaliza kugwiritsa ntchito, masulani, yeretsani, ndikuyang'anani chidacho. Bwezerani ziwalo zilizonse zowonongeka. Ikani mafuta odzola pazida zonse mukakonzanso.

(2) Mukatsuka lamba wa stator, musagwiritse ntchito nthunzi kuti mupewe kukalamba kwa labala.

(3) Sungani chidachi m'nyumba yosungiramo zinthu zopumira bwino. Sungani kutentha pakati pa 10°C ndi 25°C, ndi chinyezi chosapitirira 85%. Pewani kuwala kwa dzuwa ndi mvula.
