WHEATLEY FLG.7036 Mud Pump

Khoom siv thiab kev tsim kho: lub zog kawg ncej ntawm Wheatley twj tso kua mis yog ua los ntawm cov nplej zoo thiab ib thooj cam khwb cia hlau los ntawm precision casting. Kev ua haujlwm yog qhov tseem ceeb.

Precision Machining: tom qab lub thav duab yog cam khwb cia, nws yuav tsum precisely dhuav los xyuas kom meej qhov tseeb dimension thiab coaxiality ntawm lub crankshaft thiab iav ncej bearing lub rooj, muab ib tug ruaj khov thiab tas li siv rau lub kis tau tus mob system. Qhov kev ua tiav qhov kawg ntawm kev ruaj ntseg ntawm cov khoom siv hauv paus yog thawj kauj ruam hauv kev txuas lub neej ntawm lub tshuab.

Crankshaft thiab gear tsheb ciav hlau- lub plawv ntawm lub zog xa mus

Crankshaft tsim thiab cov ntaub ntawv: lub twj tso kua mis Wheatley siv lub cim offset crankshaft tsim. Los ntawm me ntsis hloov lub crankshaft centerline, tus tsim muaj peev xwm txo tau lub lateral thrust ntawm lub piston ntawm lub connector pas nrig thaum lub sij hawm ua hauj lwm stroke, yog li txo qhov kev sib txhuam ntawm lub crosshead thiab cov ntawv qhia phaj. Lub crankshaft nws tus kheej yog ua los ntawm siab -lub zog cam khwb cia hlau hlau. Cov khoom siv no muaj kev qaug zog tawg zoo heev thiab tawv vim nws cov spheroidal graphite tis, uas yog qhov zoo tagnrho rau kev tiv thaiv kev ntxhov siab ntawm cov twj tso kua mis reciprocating.

Gear set design and material: Fais fab kis tau los ntawm kev txuas mus ntxiv - hniav Sykes herringbone gears. Rau qhov siab tshaj plaws, cov iav tseem ceeb yog ua los ntawm cov cua sov- kho cov qib high ductile hlau, thaum lub pinion yog machined thiab hardened los ntawm forged alloy steel.

Bearings, txuas rods thiab crossheads - rau siab loads

Bearing configuration: ob qho tib si crankshaft thiab iav shafts tau txais kev txhawb nqa los ntawm lub luag haujlwm hnyav tapered los yog kheej kheej cov menyuam bearings rau qhov zoo tshaj plaws load peev xwm thiab lub neej ntev. Cov kabmob zoo no ua kom muaj kev ua haujlwm zoo thiab muaj tseeb ntawm kev sib hloov qhov chaw nyob rau hauv lub siab zoo.

Txuas pas nrig thiab crosshead: tus pas nrig txuas yog ua los ntawm cov ntu hnyav casting nrog hloov tau babbitt-lined steel plhaub bushing ntawm qhov kawg loj thiab bronze bushing ntawm me kawg. Qhov kev tsim no tsis yog tsuas yog ruaj khov, tab sis kuj yooj yim los kho lub gasket kom them nyiaj rau kev hnav thiab tsim kua muag, yooj yim rau kev tu vaj tse. Lub crosshead yog ua los ntawm cov hlau cam khwb cia zoo lossis hlau, thaum cov lus qhia crosshead yog ua los ntawm manganese bronze. Raws li cov khoom siv zoo heev, manganese bronze yog siv nrog cam khwb cia hlau los yog cam khwb cia hlau los tsim cov zawv zawg interface nrog tsis tshua muaj kev sib txhuam coefficient thiab hnav tsis kam, uas zoo txo ​​qhov tsim hluav taws xob thiab tiv thaiv hnav.

Lubrication system: tag nrho lub zog kawg ntawm kev siv yooj yim thiab tsis tshua muaj kev ntseeg siab ua ke ntawm txaws- hom thiab lub ntiajteb txawj nqus muab lubrication system.

Lub tog raj kheej thaiv- lub fortress ntawm siab

Cov khoom siv thiab kev tsim kho: lub tog raj kheej thaiv yog lub hauv paus ntawm qhov kawg hydraulic, nws cov khoom txheem yog lub zog siab ductile hlau. Cov hlau ductile tau xaiv vim nws tsis tsuas yog muab lub peev xwm zoo tshaj plaws, tab sis kuj muaj kev ua haujlwm zoo thiab kev ua haujlwm zoo ntawm kev co, uas yuav pab txo qis qhov siab ntawm lub cev ntawm ob lub - ua haujlwm twj tso kua mis. Lwm cov khoom siv xws li forged carbon steel kuj muaj rau cov ntawv thov uas yuav tsum muaj kev tiv thaiv corrosion tshwj xeeb lossis lub zog siab dua. Lub hau npog lub tog raj kheej thiab lub tog raj kheej lub tog raj kheej siv cov ntsia liaj qhov rooj ruaj khov tsim, uas ua kom muaj kev ruaj ntseg sealing nyob rau hauv siab siab thiab yooj yim disassembly thiab sib dhos thaum tu.

API 7K ua raws: tag nrho cov qauv tsim ntawm hydraulic kawg, tshwj xeeb tshaj yog qhov ntev thiab siab ntev ntawm lub valve chamber, nruj me ntsis raws li API 7K specifications. Qhov no tsis yog tsuas yog kev lav phib xaub ntawm cov khoom muaj kev nyab xeeb thiab zoo, tab sis kuj txhais tau tias nws qhov chaw tsis muaj zog muaj kev sib hloov ua lag luam zoo, uas muab kev yooj yim zoo rau cov neeg siv khoom seem khoom thiab ntawm - thaj chaw tu.

Hnav zoo heev-cov khoom tiv thaiv (cov khoom hnav)

Lub tog raj kheej liner- thawj kab ntawm kev tiv thaiv kev hnav

Lub tog raj kheej liner yog lub puab kab noj hniav ntawm lub piston reciprocating motion, uas yog ncaj qha mus rau qhov yaig thiab hnav ntawm cov dej drilling, thiab yog ib qho ntawm cov khoom siv ceev tshaj plaws ntawm hydraulic kawg 1. Peb muab ntau yam khoom siv rau kev hloov mus rau kev ua haujlwm sib txawv thiab kev xav tau nyiaj txiag.

Standard Option: File Hard Steel Liners: Ua los ntawm siab- zoo forged Steel nrog carburized hardened bore thiab ib tug deg hardness ntawm HRC Ntau tshaj los yog sib npaug rau 58-62. Cov kab no muab cov kev daws teeb meem txhim khu kev qha thiab raug nqi rau cov txheej txheem drilling.

Cov kev xaiv siab tshaj: siab chromium bimetallic lub tog raj kheej liner: Cov qauv yog tsim los ntawm ob ntu: lub plhaub yog ua los ntawm lub zog siab forged steel los tiv thaiv kev nyuaj siab; lub tes tsho sab hauv yog ua los ntawm cov khoom siv siab chromium hlau alloy los ntawm cov txheej txheem centrifugal casting. Tom qab kev kho cua sov, qhov hardness ntawm lub puab qhov tuaj yeem ncav cuag HRC Ntau dua lossis sib npaug ntawm 62-69, uas ua rau cov chromium alloy siab muaj zog abrasive hnav tsis kam thiab corrosion kuj. Raws li kev ua haujlwm ib txwm muaj, nws lub neej kev pabcuam tuaj yeem tshaj 800 teev. Tsis tas li ntawd, "HP daim di ncauj" tsim tau zoo tiv thaiv qhov kev pheej hmoo ntawm kev swb ntawm lub puab casing nyob rau hauv kev kub siab los ntawm kev siv tshuab xauv.

Piston thiab piston pas nrig -lub zog thiab toughness hauv kev txav

Piston: Lub piston yog cov khoom tseem ceeb uas ua rau lub siab. Peb lub piston muaj ob ntu: lub hauv paus thiab roj hmab. Cov tub ntxhais piston yog forged los ntawm cov hlau zoo hlau xws li 42CRMO lossis 45 # steel kom muaj zog txaus thiab toughness nyob rau hauv siab. Piston rubbers muaj nyob rau hauv ntau yam ntaub ntawv nyob ntawm seb cov dej drilling system:

Nitrile roj hmab (NBR) : haum rau cov dej ib txwm siv -raws li av nkos, muaj kev hnav zoo thiab tus nqi- zoo.

Polyurethane (PU) : nyob rau hauv cov xwm txheej hnyav dua xws li roj-raws li av nkos, hluavtaws av lossis kub thiab kub siab, cov ntaub ntawv polyurethane qhia tau zoo dua hnav tsis kam, roj tsis kam thiab tsim kua muag, uas tuaj yeem ua rau lub neej ntev.

Piston pas nrig: lub piston pas nrig yog ib qho tseem ceeb ntawm kev sib txuas ntawm lub zog kawg thiab hydraulic kawg, thiab raug rau qhov tensile thiab compressive alternating stresses. Peb siv forged alloy steel li raw khoom, tom qab nruj kev kho cua sov txheej txheem los optimize nws txhua yam khoom. Tom qab ntawd, qhov saum npoo ntawm lub cev pas nrig yog tawv chromium plated thiab precision hauv av los ua ib qho zoo heev (roughness Ra tsawg dua los yog sib npaug rau 0.4), tawv thiab corrosion- tiv thaiv txheej, uas tuaj yeem siv los txhim kho corrosion ntawm lub pas nrig lub cev, qhov no yog qhov tseem ceeb los ua kom lub neej ntev ntawm cov ntim ntim thiab tiv thaiv kom tsis txhob muaj zog ntawm hydraulic kawg.

Valves thiab rooj zaum -precision seals ntawm kev kub siab heev

Lub valve sib dhos tswj cov unidirectional ntws ntawm cov dej drilling, thiab nws cov kev ua tau zoo cuam tshuam ncaj qha rau qhov ua tau zoo ntawm lub twj tso kua mis. Thaum ob lub - lub twj tso kua mis rov qab kev taw qhia ntawm txhua qhov mob stroke, lub valve sib dhos yuav ua rau muaj kev cuam tshuam loj heev.

Cov khoom siv thiab cov txheej txheem tsim khoom: tus qauv valve hom yog tis qhia valve, lub cev lub cev thiab lub rooj zaum yog ua los ntawm 20CrMnTi thiab lwm yam siab - zoo alloy steel tag nrho tuag forging. Lub forging xyuas kom meej lub compactness ntawm lub internal qauv ntawm cov khoom thiab zoo heev lub zog. Lub forged dawb paug yog tom qab ntawd raug rau cov txheej txheem kev kho cua sov xws li carburizing thiab quenching, kom nws ua hauj lwm saum npoo hardness ncav cuag HRC Ntau tshaj los yog sib npaug rau 60, thaum tuav zoo toughness nyob rau hauv cov tub ntxhais los tiv thaiv tej yam load.

Tsim thiab kev ua tau zoo: cov txheej txheem tsim khoom no ua kom muaj kev sib haum xeeb ntawm lub cev thiab lub rooj rau kev txhim khu kev qha "Bubble Class" sealing txawm nyob rau hauv lub siab tsis tshua muaj siab thiab av nkos ntxuav, zoo tiv thaiv rov qab los, yog li ua kom lub twj tso kua mis ua haujlwm tau zoo. Rau corrosive brine thiab lwm yam xov xwm, peb kuj tuaj yeem muab bronze valve los ua ke los muab kev tiv thaiv corrosion zoo dua.
