Lub platform tsim optimized rau kab rov tav directional drilling (HDD)
Peb muab ob lub twj tso kua mis raws li tib lub zog kawg nkaus: WDD 550, tsim los rau HDD daim ntawv thov, thiab QWS550, tsim los rau siab - cov kev pabcuam zoo xws li tawg.
WDD 550 (HDD daim ntawv thov): lub twj tso kua mis no tau nruab nrog lub siab ua haujlwm siab cam khwb cia hlau hydraulic kawg nrog lub siab tshaj plaws ua haujlwm ntawm 2,000 PSI thiab cov ntsuas txuas txuas ntawm 21,000 lbs. Qhov kev teeb tsa no ua tau raws li qhov tseem ceeb ntawm kev ua haujlwm HDD: tas mus li, loj - cov dej ntws tawm mus kom zoo tshem tawm cov txiav, thiab kev ua haujlwm siab kom ua tau raws li feem ntau ntawm HDD. Cov cam khwb cia hlau hydraulic kawg muab cov nqi zoo dua thaum ua kom muaj zog txaus thiab hnav tsis kam.
QWS550 (kev pabcuam roj siab siab): lub twj tso kua mis no siv lub zog siab dua forged alloy steel hydraulic kawg kom tiv taus kev ua haujlwm siab txog li 10,000 PSI thiab cov pas nrig txuas ntawm 59,820 lbs, kom ua tau raws li qhov xav tau ntawm kev ua haujlwm siab xws li fracturing.
Technical specifications thiab kev ua haujlwm ntau
Peb muab cov ntaub ntawv qhia meej, cov ncauj lus kom ntxaws los pab koj txheeb xyuas qhov tseeb tias WDD 550 ua tau raws li koj qhov kev xav tau.

Nco tseg: Cov ntaub ntawv kev ua tau zoo yog raws li kev hloov pauv hloov pauv rau QWS550 lub twj tso kua mis, uas muaj qhov ntws zoo ib yam li WDD 550 ntawm tib lub piston loj thiab ceev. Tus nqi siab tau raug txwv rau qhov txwv siab tshaj ntawm 2,000 PSI rau WDD 550.
Power End Architecture: lub hauv paus ntawm kev ua haujlwm tsis tu ncua
Ncej qauv
Lub zog kawg ncej ntawm lub twj tso kua mis yog qhov lav ntawm nws cov qauv kev ncaj ncees. WDD 550 siv lub siab - lub zog cam khwb cia hlau ncej. Cov graphite daim ntawv microstructure ntawm cov khoom no endows lub moj khaum nrog zoo heev los tiv thaiv - qaug zog durability, zoo heev hnav tsis kam ntawm qhov txav txav, thiab muaj peev xwm nqus tau zoo heev, uas muaj txiaj ntsig zoo rau kev txhim kho siab - kev ua tau zoo, muab lub hauv paus ruaj khov rau kev ua haujlwm tsis tu ncua hauv kev ua haujlwm hnyav.
Crankshaft thiab kis system
Lub zog ntawm lub zog xa hluav taws xob yog ncaj qha ntsig txog kev ua haujlwm thiab lub neej ntawm lub twj tso kua mis.
Forged alloy steel crankshaft: lub crankshaft yog forged nyob rau hauv ib daim ntawm siab zog alloy steel los xyuas kom meej tsis tshua muaj siab rigidity thiab qaug zog kuj nyob rau hauv siab tshaj plaws load.
Kev txhawb nqa tag nrho thiab cov kabmob siab heev: lub crankshaft muaj "Kev txhawb nqa puv" tsim nrog biconical lub ntsiab bearings thiab cylindrical roller center bearings. Cov qauv kev txhawb nqa ntau- taw tes txhawb nqa tuaj yeem faib tau zoo thiab nqa lub nra, txo qhov deflection deformation ntawm lub crankshaft hauv kev ua haujlwm, yog li tiv thaiv kev hnav ntxov ntxov ntawm bearings thiab qaug zog ntawm lub crankshaft. Qhov no tsis yog tsuas yog ua kom lub neej ntev xwb, tab sis kom ntseeg tau tias muaj kev sib raug zoo, kwv yees ua tau zoo tshaj ntau txhiab teev ntawm kev ua haujlwm tas mus li, yog li txo qis kev pheej hmoo ntawm kev poob qis.
Lubrication system
Lub WDD 550 yog nruab nrog ib qho ua tau - ua ke ntawm kev quab yuam lubrication thiab txaws lubrication. Lub kaw lus ua kom tsis tu ncua thiab txaus lubrication ntawm tag nrho cov tseem ceeb txav qhov chaw xws li crossheads, bearings thiab gears, txawm nyob rau hauv hnyav tej yam kev mob xws li tsis tshua muaj ceev los yog tsis - kab rov tav mounting. Tsis tas li ntawd, lub twj tso kua mis kuj tau nruab nrog plaub tus laus- foob nruab nrab pas nrig roj foob, tiv thaiv cov av nkos cuam tshuam lub zog kawg, ua kom cov roj lubricating huv si, txhawm rau txuas lub neej ntawm lub zog kawg. Rau kev ua haujlwm ntev - lub sijhawm ua haujlwm qis dua 200 RPM, nws raug nquahu kom nruab ib lub tshuab lubrication.
Hydraulic kawg engineering: kev ua haujlwm zoo rau kev siv
Modular tsim thiab cov ntaub ntawv
Tus qauv WDD 550 hydraulic kawg yog ua los ntawm lub zog siab cam khwb cia hlau. Cov khoom no tau raug tswj xyuas kom zoo thiab muab kev ua haujlwm zoo dua qub, hnav tsis kam thiab kev ua haujlwm zoo rau cov ntawv thov nrog 2,000 PSI qib siab. Lub hydraulic kawg tau txais kev lag luam tus qauv "Valve on valve" (L- hom) qauv, uas ua kom muaj kev ua haujlwm siab thiab kev ntseeg siab ntawm cov kua dej channel.
Cov txheej txheem tsim khoom thiab kev ruaj ntseg zoo
Txawm hais tias tus qauv WDD 550 hydraulic kawg yog qhov casting, cov txheej txheem tsim ua raws li cov qauv zoo tib yam li peb cov forged hydraulic kawg. Txhua qhov hydraulic kawg modules yuav tsum dhau cov kev xeem nruj xws li kev ntsuas siab, ntsuas qhov ntsuas qhov ntsuas thiab tsis yog- kuaj kev puas tsuaj (NDT) ua ntej xa khoom kom ntseeg tau tias ua raws li kev lag luam tshwj xeeb xws li API 7K, zam tsis muaj teeb meem zais uas yuav ua rau ntawm - qhov chaw tsis ua haujlwm.
Kev ruaj ntseg yooj yim
Peb nkag siab tob txog qhov tseem ceeb ntawm - qhov chaw tu kom zoo. Lub hydraulic kawg tsim ntawm WDD 550 tso cai rau cov neeg ua haujlwm saib xyuas "Yooj yim tshem lub piston los ntawm qhov kawg ntawm lub tog raj kheej thaiv tsis tau txav tag nrho lub tog raj kheej lossis lub tog raj kheej liner." Cov yam ntxwv no ua kom yooj yim rau cov txheej txheem hloov pauv, txo qis qis rau qhov tsawg kawg nkaus, thiab ncaj qha txhim kho koj cov khoom tsim tau.
Consumables thiab hnav-cov khoom tiv thaiv: Science of Life Extension thiab TCO txo
Xaiv qhov siab -zoo, OEM- cov khoom siv raws li kev cai yog qhov ncaj qha thiab zoo tshaj plaws los txo tus nqi tag nrho ntawm cov tswv cuab (TCO) ntawm cov twj. Txhua yam ntawm peb cov khoom siv tau suav nrog cov khoom siv qib siab thiab cov txheej txheem tsim khoom tsim los ua kom lub sijhawm ua haujlwm siab tshaj plaws thiab txuas ntxiv txij nkawm.
Liners
Lub tog raj kheej liners yog cov khoom tseem ceeb uas ncaj qha tiv taus cov av nkos. Peb muaj ntau yam kev xaiv kom haum rau cov kev khiav hauj lwm sib txawv thiab cov peev txheej.
