NOV 7-P-50 Mud Pump

Meta Description (SEO): Cov lus qhia meej rau NOV National 7-P-50 peb- lub tog raj kheej av nkos twj tso kua mis. Tshawb nrhiav kev ua haujlwm OEM kev qhia tshwj xeeb, kev ntsuas kev ua tau zoo, thiab cov ntaub ntawv ntxaws ntxaws ntawm forged alloy steel fais fab kawg, L-hom hydraulic kawg, thiab API 7K-certified Cheebtsam. Qhov no yog qhov chaw zoo tshaj plaws rau cov kws tshaj lij drilling.

Lub zog kawg yog lub hauv paus ntawm lub zog uas hloov lub zog hloov pauv ntawm tus thawj txav mus rau hauv reciprocating motion kom zoo thiab smoothly. Txhua yam yog tsim thiab xaiv kom ua tiav qhov siab tshaj plaws thiab kev ua haujlwm du, muab lub zog tsis muaj zog rau tag nrho lub twj tso kua mis.

Khib thiab iav kis system: lub caj qaum ntawm kev ua haujlwm

rake kev tsim kho

Tus tsav- sab ncej nta ib qho tseem ceeb welded steel qauv nrog ncej-weld annealing kom tshem tawm cov kev ntxhov siab sab hauv thiab xyuas kom ntev - lub sij hawm qhov ntev stability. Lub ntsiab bearing vaj tse thiab kis kabmob vaj tsev yog tsim los ua monolithic cam khwb cia hlau Cheebtsam. Qhov kev tsim qauv no muab qhov tshwj xeeb nruj thiab lub zog rau lub twj tso kua mis lub cev, muab lub pob zeb- cov ntaub ntawv sib xyaw ua ke rau cov kab ke sib kis uas muaj txiaj ntsig zoo tiv thaiv kev ua haujlwm tsis tu ncua torque thiab cyclic loads.

Gear System

Lub 7-P-50 av nkos twj tso kua mis siv ib qho herringbone hniav los yog ob chav helical iav kis tau tus mob. Qhov kev tsim khoom siv qib siab no muaj ntau yam zoo:

Smooth, siab torque kis tau tus mob: Vim muaj kev sib koom ua ke ntawm ntau qhov chaw ntawm cov hniav, lub zog sib kis tau zoo heev thiab tsis tu ncua, txo qis kev co thiab suab nrov.

Kev tshem tawm ntawm axial thrust: Lub symmetrical helix kaum sab laug thiab sab xis tshem tawm ib leeg tawm, tshem tawm qhov xav tau rau qhov loj thrust bearing, yog li ua kom yooj yim cov kabmob configuration thiab txo qhov muaj peev xwm ua tsis tiav.

AGMA tus qauv: Txhua lub zog tau ua tiav rau cov qauv siab ntawm American Gear Manufacturers Association (AGMA), ua kom ntseeg tau zoo meshing raug thiab ua haujlwm ntev.

Crankshaft thiab txuas pas nrig: forged los tiv thaiv qaug zog

Lub crankshaft, ua hauj lwm raws li lub hwj chim chav tsev lub plawv, endures zoo heev alternating stresses. Txhawm rau kom muaj kev ruaj khov, peb tsuas yog siv cov cuab yeej forging siv siab - lub zog alloy steels xws li 42CrMo lossis 35CrMo. Tsis zoo li cam khwb cia crankshafts, forging los ntawm siab - siab rau hammering los yog nias refines hlau nplej kom haum raws li cov qauv, zoo tshem tawm cov tsis xws luag xws li porosity thiab voids nyob rau hauv castings. Txhua forged crankshaft tau txais kev kho cua sov kom nruj (quenching thiab siab -kub tempering). Ib yam li ntawd, txuas rods yog tsim los ntawm hwm forged alloy steel, nrog lawv cov articulated sib koom tsim kom ntseeg tau muaj zog thiab txhim khu kev qha kev sib txuas ntawm crankshaft thiab crosshead.

Crosshead sib dhos thiab lubrication system

Crosshead thiab qhia phaj

Lub crosshead sib dhos yog tus yuam sij rau kev hloov pauv ntawm kev sib hloov mus rau cov lus tsa suab. Lub cev hla lub taub hau yog nrum tag nrho ntawm cov hlau nplaum los yog siab - zoo cam khwb cia hlau, nrog lub zog tensile ntawm ntau tshaj 600MPa, thaum lub phaj qhia yog ua los ntawm hnav- tiv taus manganese bronze lossis tin bronze.

Lub hwj chim kawg thiab hydraulic kawg yog nruab nrog qib siab plaub- txheej txheej sealing qauv, uas zoo tiv thaiv cov av nkos los ntawm kev cuam tshuam lub hwj chim kawg lossis cov roj lubricating los ntawm kev xau mus rau qhov kawg hydraulic, kom ntseeg tau tias purity ntawm txhua qhov system.

Tag nrho lub hwj chim kawg txais yuav ob lub lubrication system sib txuas ua ke yuam lubrication thiab txaws lubrication.

Lub zog lubrication, uas tau tsav los ntawm lub twj tso kua mis roj, xa cov roj lim huv huv rau cov kev sib txhuam tseem ceeb xws li cov kabmob tseem ceeb, pinion bearing thiab crosshead, thaum txaws lubrication npog lwm qhov txav mus los, kom paub meej, tsis muaj qhov tuag taus lubrication thiab cov cua kub kom zoo.

L- hom cais hydraulic lub tog raj kheej: Kev lag luam benchmark rau kev kho niaj hnub

7-P-50's L-shaped split hydraulic lub tog raj kheej tsim, uas cais cov nqus thiab tso tawm valve chambers, muaj txiaj ntsig ua haujlwm tseem ceeb tshaj li cov qauv monoblock.

Qhov tseem ceeb txo tus nqi txij nkawm: Thaum hnav tshwm sim feem ntau ntawm qhov kawg suction, tus neeg siv tsuas yog yuav tsum tau hloov lub tshuab nqus tsev, tsis yog hloov tag nrho cov khoom kim heev hydraulic kawg, txuag cov nqi seem.

Txhim kho kev txij nkawm thiab kev nyab xeeb: Cov qauv sib cais ua rau kev hloov cov khoom tsis zoo xws li li qub thiab lub rooj zaum valve yooj yim heev. Cov neeg saib xyuas tuaj yeem nkag tau yooj yim thiab nrawm nkag mus rau lub hom phiaj yam tsis muaj kev cuam tshuam ntau ntawm cov khoom tsis sib xws, txo qis sijhawm thiab txo qhov kev pheej hmoo ntawm kev nyab xeeb ntawm - chaw ua haujlwm.

Lub tog raj kheej module kev ncaj ncees: forged rau kev kub siab

Txhua module nyob rau hauv hydraulic kawg yog ib qho tseem ceeb tivthaiv tsim los tiv taus siab heev. Peb cov modules yog forged raws li ib tug ib thooj los ntawm siab - zoo alloy steels xws li 35CrMo, 40CrMnMo, los yog AISI 8620. Tag nrho cov modules undergo nruj heev tshav kub kev kho mob ncej- ua kom ua tau ib tug hardness ntawm HB285-330, ua raws li los ntawm non-destructive testing. sij hawm ua haujlwm siab. Cov kev ua raws cai nruj raws li API 7K cov qauv ua kom muaj kev nyab xeeb hauv kev ua haujlwm siab txog li 5000 PSI lossis siab dua.

Hauv -Kev tsom xam qhov tob ntawm qhov tsis zoo: kev kos duab ntawm cov khoom thiab cov txheej txheem

Qhov kev ua tau zoo ntawm cov khoom hnav ncaj qha txiav txim siab ua haujlwm tsis tu ncua thiab kev saib xyuas tus nqi ntawm cov av nkos twj tso kua mis. Peb muab ntau yam saum toj kawg nkaus - qib coj qhov chaw ntawm cov khoom sib txawv thiab cov txheej txheem kom ua tau raws li cov kev cov nyom ntawm cov tshuab drilling kua sib txawv thiab kev ua haujlwm.

Lub tog raj kheej liner: hnav-cov ntaub ntawv tiv taus

Siab -Chromium Bimetallic Lub Tes Tsho: Lub plhaub sab nrauv yog tsim los ntawm siab- lub zog forged steel (xws li AISI 1045), xa cov zog tshwj xeeb compressive. Sab hauv liner yog tsim los ntawm centrifugal casting siv high -chromium cam khwb cia hlau (tshaj 26% chromium cov ntsiab lus). Tom qab kev kho cua sov, nws cov phab ntsa sab hauv ua tiav qhov hardness ntawm HRC Ntau dua lossis sib npaug ntawm 60-65, kom ntseeg tau tias hnav tsis kam. Precision honing txheej txheem tsim ib daim iav- du sab hauv, lav tshaj 800 teev ntawm kev pabcuam ruaj khov.

Zirconia Ceramic Lub tog raj kheej Liner: Qhov kev tsim tshiab no ua ke nrog zirconia ceramic liner nrog forged steel casing los ntawm cov txheej txheem tsim khoom. Nrog lub hardness siab tshaj HRC 90, cov khoom siv ceramic ua kom pom kev hnav zoo dua thiab kev tiv thaiv corrosion piv rau cov pa chromium-raws li alloys, xa lub neej kev pab ntawm 2,000 txog 4,000 teev lossis ntev dua. Qhov tshwj xeeb tshaj plaws hauv qhov chaw zoo txo ​​qis kev sib txhuam ntawm lub piston thiab liner, yog li txuas ntxiv lub piston lub neej ua haujlwm thaum txo qis thermal load ntawm qhov cua txias.

Piston: Siab siab foob

Lub piston sib dhos muaj quenched thiab tempered 45 # steel los yog 40Cr forged piston core ua ke nrog siab -kev ua tau zoo polyurethane roj hmab. Peb cov roj hmab polyurethane (Urethane) tshwj xeeb yog tsim los rau dej-raws li, roj-raws li, los yog hluavtaws slurry daim ntaub ntawv, featuring tshwj xeeb hnav tsis kam, kua muag kuj, thiab extrusion kuj, thaum tuav ruaj khov sealing kev ua tau zoo ntawm kub txog 230℃F (110 degree).

Valve thiab lub rooj zaum valve: kua tswj chaw

Lub valve sib dhos yog ib qho ntawm cov khoom siv uas muaj qhov ua haujlwm siab tshaj plaws thiab feem ntau cuam tshuam rau hauv cov av nkos. Peb lub cev lub cev thiab lub rooj zaum yog sib koom ua ke los ntawm siab - zoo alloy steel (20CrMnTi) los ntawm precision machining.

Cov txheej txheem carburizing thiab quenching cua sov txheej txheem tsim cov txheej txheej sib sib zog nqus ntawm qhov chaw nrog lub hardness ntawm HRC Ntau dua los yog sib npaug rau 60, thaum lub hauv paus tseem muaj qhov zoo toughness los tiv taus siab - zaus cuam tshuam. Cov roj hmab valve yog ua los ntawm hnav- cov khoom siv tiv taus.

Cov khoom siv polyurethane, ua ke nrog API-5 tag nrho qhib valve lub rooj tsim, ua kom muaj peev xwm ua kom muaj peev xwm ua tau zoo, txo qis kev yaig, thiab ua kom lub neej ua haujlwm ruaj khov ntawm ntau dua 300 teev.

Peb muab 7-P-50 twj tso kua mis nrog ob lub zog teeb tsa kom tau raws li ntau yam kev drilling qhov tob thiab kev ua haujlwm xav tau. Tag nrho cov ntaub ntawv ua tau zoo yog xam raws li 90% mechanical efficiency thiab 100% volumetric efficiency, muab cov lus qhia meej rau koj qhov kev npaj ua haujlwm.
