Cov khoom zoo heev thiab precision workmanship
Valve lub cev - lub hauv paus indestructible ntawm lub zog
Kev xaiv khoom: Lub cev valve yog tsim los ntawm siab -lub zog qis- alloy steel, feem ntau yog qib AISI 4130 (chromoly steel). Cov khoom no muaj npe nrov rau nws cov khoom siv tshwj xeeb, nrog rau lub zog tensile txog li 560 MPa thiab tawm lub zog ntawm 460 MPa. Nws zoo heev toughness thiab qaug zog ua hauj lwm pab kom nws ua hauj lwm pressures siab li 5,000 PSI (345 Bar) los yog ntau dua.
Kev tsim khoom: Lub cev valve yog tsim los ntawm kev sib koom ua ke. Piv nrog rau cov txheej txheem casting, forging refines thiab homogenizes hlau nplej sab hauv thaum tshem tawm tej yam tsis xws luag sab hauv xws li porosity thiab voids. Cov txheej txheem no txhim kho kev ncaj ncees ntawm cov txheej txheem thiab siab -cov kabmob muaj peev xwm, tshem tawm cov kev nyab xeeb kev nyab xeeb los ntawm cov khoom tsis zoo.
Lub hauv paus ntawm hydraulic piston - kev ua tau zoo thiab corrosion kuj
Cov khoom xaiv: Lub piston yog ua los ntawm qib siab - stainless hlau. Nyob rau hauv siab - qauv kev ua tau zoo thiab cov khoom sib hloov tau, nws tau teev tseg kom siv 17-4 PH (UNS S17400) nag lossis daus hardened stainless hlau.
Cov txheej txheem kho cua sov thiab ua raws li: Kev kho cua sov yog qhov tseem ceeb rau kev qhib lub peev xwm ntawm 17-4 PH. Hauv cov cheeb tsam acidic uas muaj hydrogen sulfide (H₂S), kev xaiv thiab ua cov khoom yuav tsum nruj me ntsis ua raws li NACE MR0175 cov qauv los tiv thaiv sulfide kev nyuaj siab tawg (SSC) - hom tsis ua haujlwm tseem ceeb uas xav tau kev tswj xyuas nruj.
Sealing system - tsim rau lub neej ntev thiab kev sib raug zoo tshuaj lom neeg
Kev ntseeg siab ntawm sealing system ncaj qha txiav txim siab txog kev pabcuam lub neej thiab kev saib xyuas tus nqi ntawm lub valve.
Lub tswv yim tsim: Lub ntsiab elastomer foob yog cleverly tsim sab nraum lub mainstream channel, minimizes ncaj qha kev sib cuag nrog siab txaus tus nqi thiab siab abrasion ntawm drilling kua, uas yog lub ntsiab tsim lub tswv yim mus cuag lub sealing lub neej.
Cov Khoom Siv Xaiv: NOV muaj ntau yam kev xaiv elastomer rau cov tshuab drilling kua sib txawv. Cov txheej txheem kev teeb tsa yuav siv NBR (Nitrile Rubber), uas muab cov roj zoo heev. Txawm li cas los xij, txhawm rau hais txog qhov kub thiab txias thiab tshuaj ntxiv nyob rau hauv niaj hnub complex drilling kua tshuab, HNBR (Hydrotreated Nitrile Rubber) tau dhau los ua qhov kev xaiv zoo tshaj. Muab piv rau NBR, HNBR ua kom pom qhov dav dav ntawm qhov siab ntev (txog 160 degree), txhim kho hnav tsis kam, thiab zoo corrosion kuj tiv thaiv cov xov xwm hnyav nrog rau lub caij ntuj no diesel-raws li av nkos, acids, alkalis, thiab ntau yam tshuaj kho mob. Qhov no ua kom lub neej ntev sealing thiab txo cov kev tu ncua.
Valve npog los ua ke - kev tiv thaiv tag nrho, lub neej lubrication
Valve npog los ua ke yog lub plawv ntawm tag nrho lub valve mechanical zog, nws sab hauv kev koom ua ke ntawm crank, txuas pas nrig, caij nplooj ntoos hlav thiab lwm yam precision kis tau tus mob qhov chaw.
Cov qauv tsim: tag nrho lub valve npog lub rooj sib txoos txais cov qauv tsim, zoo li lub fortress muaj zog, cais tag nrho cov sab hauv precision txav qhov chaw los ntawm cov plua plav, av nkos, ntsev tsuag thiab lwm yam pa phem uas feem ntau siv nyob rau hauv qhov chaw drilling, kom ntseeg tau tias lub zog du thiab txhim khu kev qha ntawm lub tshuab.
Internal lubrication: Lub valve npog yog ua ntej - puv nrog siab - roj ua haujlwm. Qhov no tsis yog tsuas yog ua kom ntseeg tau tias qhov rov pib dua txheej txheem tswj kev sib txhuam qis thiab kev ua haujlwm du yam tsis ua raws li ntau txhiab lub voj voog, tab sis kuj tseem muab kev tiv thaiv corrosion ntev rau txhua qhov hlau sab hauv, ua tiav lub sijhawm ntev - tu lub sijhawm- dawb.
Cov lus hauv qab no qhia txog cov khoom siv tshwj xeeb ntawm cov khoom tseem ceeb ntawm NOV Hom B kev nyab xeeb valve thiab lawv qhov zoo ntawm engineering.
