1. Taw qhia
Sucker rods thiab polished rodsyog ob qho tseem ceeb ntawm cov twj tso kua mis reciprocating piston rau rho cov roj los yog dej los ntawm qhov dej. Txawm hais tias lawv ua hauj lwm ua ke nyob rau hauv tandem, muaj qee qhov sib txawv ntawm lawv nyob rau hauv cov nqe lus ntawm lawv tsim, kev ua haujlwm, thiab kev saib xyuas.
2. Sucker Rods
Sucker rods yog cov khoom sib txuas tseem ceeb uas xa cov torque thiab nce / nqis los ntawm lub twj tso kua mis ntawm qhov chaw mus rau lub piston los ua ke nyob rau hauv downhole nyob ze ntawm lub reservoir kua. Ua los ntawm high-strength steel alloys, sucker rods muaj ib tug elongated khoom bar tsim nrog threaded xaus. Lawv txuas nrog los ntawm cov couplings los tsim cov hlua hlua uas txuas mus rau hauv qhov dej.
(1) Lub luag haujlwm tseem ceeb ntawm cov pas nrig muaj xws li:
-Txoj kev rub thiab nqa lub zog nqa cov roj / dej rau saum npoo
- Nrog rau cov dynamic cyclical loads thaum lub sij hawm siv twj tso kua mis
- Muab cov khoom sib txuas ntawm lub tshuab nqus tsev twj thiab lub twj tso kua mis downhole
- Ua kom haum cov khoom thauj khoom thaum lub pas nrig ua raws li qhov sib txawv ntawm lub qhov dej
(2) Kev xaiv zoo ntawm cov khoom siv pas nrig, txoj kab uas hla, thiab qib ua kom muaj kev ncaj ncees tsim nyog los ua cov haujlwm no nyob rau lub sijhawm ntev. Kev tshuaj xyuas ib ntus thiab kev tiv thaiv txij nkawm ntawm cov pas nrig yog yuav tsum tau kuaj corrosion thiab kev puas tsuaj teeb meem ntxov.
3. Polished Rods
Cov pas nrig polished ua rau sab sauv ntawm cov hlua hlua uas txuas los ntawm kev sib txuas mus rau horsehead pivoting beam ntawm lub twj tso kua mis. Raws li lub npe qhia, polished rods muaj ib tug du polished sab nrauv nto. Lawv feem ntau yog ua los ntawm corrosion-resistant stainless hlau los yog chrome-plated alloy hlau.
(1) Lub luag haujlwm tseem ceeb ntawm tus pas nrig polished yog:
- Muab lub ntsej muag du kom sib khi nrog lub thawv ntim khoom thiab tiv thaiv kom tsis txhob yaig
- Txo qhov hnav thiab kev sib txhuam thaum nws swb los ntawm lub thawv ntim khoom
- Ua hauj lwm raws li ib qho kev taw qhia ntawm lub downhole twj tso kua mis
- Tiv thaiv cov hlua hlua los ntawm kev puas tsuaj corrosion
(2) Polished rods yog machined los kaw diametrical thiab straightness kam rau ua. Lawv lub ntsej muag du tiav tso cai rau cov roj nplua nyeem kom siv tau los txo kev sib txhuam. Kev tshuaj xyuas tsis tu ncua ntawm tus pas nrig saum npoo yog xav tau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, nws yog qhov yuav tsum tau yuav tsum tau kuaj xyuas, nws yuav tsum tau kuaj xyuas.
4. Qhov txawv tseem ceeb ntawm Sucker Rods thiab Polished Rods
Txawm li cas losnqus cov pas nrig thiab polished rodsua hauj lwm ua ke thaum lub sij hawm siv cov txheej txheem, muaj qee qhov sib txawv ntawm lawv:
- Sucker rods muaj ntxhib sab nraud raws li tiv thaiv polished du sab nrauv ntawm polished rods
- Cov qub ua rau feem ntau ntawm cov hlua hlua ntev nrog rau tom kawg nkaus xwb rau saum
- Cov qub yog threaded ntawm ob qho kawg thaum lub tom kawg muaj threading nkaus xwb ntawm ib kawg
- Cov tom kawg yog tsim los ntawm tshwj xeeb corrosion-resistant alloys thaum sucker rods siv high-strength steel
- Cov kev paub dhau los ntau dua kev hloov pauv kev ntxhov siab los ntawm kev nqa cov khoom thaum lub sijhawm tom kawg pom qis dua li qub
- Cov yav tas yuav tsum tau kev tiv thaiv los ntawm nto corrosion thaum sucker rods ntsib nrog corrosion los ntawm cov dej zoo
- Kev ua tsis tiav ntawm txoj hlua hlua feem ntau yuav tshwm sim hauv cov pas nqus dej ntau dua li cov pas nrig polished
- Kev tshuaj xyuas thiab kev saib xyuas ntawm cov pas nrig txuas nrog lub sijhawm thiab nqi ntau dua
Sucker rods thiab polished rodsua hauj lwm synergistically los hloov cov lus tsa suab ntawm lub twj tso kua mis mus rau ib tug reciprocal txav uas nqa roj / dej rau saum npoo. Thaum sucker rods ua qhov hnyav lifting downhole, polished rods muab ib tug du transitional interface ntawm qhov chaw.
