Izixhobo Zokusebenza | Udidi Lokugrumba-Lokugaya-Lokugaya | Imoto Yokufuduka Efanelekileyo

1. Izicelo

Isebenza ngoxinzelelo lwe-hydraulic, i-PDM iqhuba indibano yokugrumba emngxunyeni ngokujikeleza, ivumela imisebenzi efana nokugrumba, ukugaya, kunye nokuphambukisa umkhondo.

2. Ulwakhiwo

I-PDM ngokuyintloko iqulathe icandelo eliphezulu,ivalvu yokudlula, i-stator, i-rotor, i-coupling, i-water passage sub, i-bearing assembly, i-drive shaft, kunye ne-bottom sub.

3. Umgaqo-nkqubo Wokusebenza

I-PDM iguqula amandla olwelo olunoxinzelelo oluphezulu abe ngamandla oomatshini ngokusebenzisana kwerotor kunye ne-stator. Ulwelo olunoxinzelelo oluphezulu lungena kwiigumbi ezivaliweyo ezenziwe phakathi kwerotor kunye ne-stator. Umahluko woxinzelelo ubangela ukuba i-rotor ijike ecaleni kwetshaneli ejikelezayo ye-stator. I-rotor ijikeleza ngendlela engaqhelekanga kwi-axis ye-stator, ngelixa ijikeleza ngaxeshanye kwi-axis yayo, iqhuba ukujikeleza kwe-drill bit.

4. Iinkcukacha zobuGcisa

Umgangatho osebenzayo: I-SY/T 5383 Positive Displacement Motor

Imodeli yeenkcukacha

imizekelo:

• 9LZ95×7.0 : Ububanzi bangaphandle obuyi-95 mm, i-hydraulic motor eyi-9/10 lobe ratio, i-bit nozzle pressure drop eyi-7 MPa.
• 5LZ165×7.0Ⅱ : Ububanzi bangaphandle yi-165 mm, i-hydraulic motor enomlinganiselo we-5/6 lobe, i-bit nozzle pressure drop 7.0 MPa, utshintsho lwesibini loyilo lwe-PDM yomzimba othe tye.
• 5LZ197×7.0-SWFG: Ububanzi bangaphandle yi-197 mm, i-5/6 lobe ratio motor hydraulic, i-double-bet housing ene-stabilizer, i-hollow rotor ene-flow diversion, ubushushu obuphezulu bokusebenza yi-150°C, i-bit nozzle pressure drop eyi-7.0 MPa.

5. Inkqubo Yokusebenza

(1) Hlanganisa i-BHA.

(2) Baleka kancinci ukuya kuthi ga kwi-3–5 m ngaphezu kobunzulu obujoliswe kubo, qala iimpompo zijikeleze kwaye ucoce umthombo. Isantya sokubaleka se-30 m/min siyacetyiswa. Gcwalisa umtya wokubhola ngolwelo olucocekileyo lokujikeleza rhoqo emva kwe-500 m yokungena.

(3) Yehlisa kancinci, uze uqalise ukubhoboza. Ubunzima kwi-bit (WOB): 5–15 kN. Isantya sokuhamba: 500–600 L/min.

(4) Tsala uphume emngxunyeni (POOH).

6. Amanyathelo okuzikhusela

(1) Qinisekisa ukuba umphezulu wePDM uqinile ngexesha lovavanyo lomphezulu.

(2) Ulwelo lokujikeleza kwegazi kufuneka lucoceke.

(3) Ulwelo olubuyayo kufuneka luhlolwe kwaye lususwe edamini.

(4) Intloko yomthombo mayixhotyiswe ngesixhobo sokuzivalela ukuze izinto ezincinci zingawi emthonjeni.

(5) Coca kakuhle imithombo ngaphambi kokutshintsha iindawo ezizimeleyo nasemva kokugqiba ukubhoboza.

7. Ukugcinwa kunye nokugcinwa

(1) Emva kokusetyenziswa, qhaqha, coca, kwaye uhlole isixhobo. Buyisela naziphi na iindawo ezonakeleyo. Faka ioyile yokuthambisa kuzo zonke izinto ngexesha lokuphinda udibanise.

(2) Xa ucoca i-stator rubber lining, musa ukusebenzisa umphunga ukuthintela ukuguga kwerabha.

(3) Gcina isixhobo kwindawo yokugcina umoya kakuhle. Gcina ubushushu buphakathi kwe-10°C kunye ne-25°C, kunye nomswakama ongadluli kwi-85%. Kuphephe ukukhanya kwelanga ngqo kunye nemvula.
