LJR PUMPS EWS-440
Nqe lus piav qhia: PUMPS EWS-440 - 440 HP peb- lub tog raj kheej av nkos twj tso kua mis tsim kom muaj kev ntseeg siab tshaj plaws thiab tus nqi qis kawg nkaus ntawm cov tswv cuab. Tshawb nrhiav cov ncauj lus ntxaws ntxaws ntawm nws cov forged steel fais fab kawg, cov khoom siv hydraulic siab, thiab API 7K-raws li kev sib dhos.
Lub zog kawg- lub hauv paus ruaj khov rau forging thiab precision engineering
Cov qauv qauv: optimization ntawm rigidity thiab lub zog rau qhov hnyav piv
Lub EWS-440 lub hwj chim- kawg ncej nta ib tug welded qauv ntawm siab- lub zog steel daim hlau, nrog post-weld kev nyuaj siab nyem kev kho mob los xyuas kom meej qhov seem stability thiab tshwj xeeb yam ntxwv lub zog. Qhov tseem ceeb load-bearing thaj chaw nrog rau lub crankshaft thiab lub ntsiab bearing vaj tse yog ntxiv dag zog rau tshwj xeeb kev ntsuas, xa unmatched rigidity.
crankshaft: du thiab txhim khu kev qha fais fab tub ntxhais
Cov ntsiab lus tseem ceeb ntawm chav tsev fais fab yog crankshaft forged los ntawm siab -zoo 42CrMo alloy hlau. Qhov no precision-engineered ncej tau nruj ntau- theem kev kho cua sov (normalizing thiab quenching), xa tshwj xeeb qaug zog tiv thaiv thiab cuam tshuam toughness. Fais fab kis tau los ntawm ib qho kev tsim tshwj xeeb herringbone gear system nrog lub iav piv ntawm 4.578: 1.
Crosshead thiab txuas pas nrig: durability guarantee nyob rau hauv reciprocating tsab ntawv tsa suab
EWS-440's crosshead yog monolithic casting ntawm high-qib hlau hlau, xa tshwj xeeb hnav tsis kam thiab kev co damping. Nws cov ntawv qhia daim hlau muaj cov khoom siv tooj liab hloov tau-ib lub sijhawm- kuaj cov khoom muaj npe nrov rau nws cov yam ntxwv tsis tshua muaj kev sib txhuam. Qhov kev sib xyaw ua ke tshiab ntawm cov hlau nplaum thiab cov tooj liab no ua pov thawj kev sib txhuam tsim hauv engineering xyaum.
Lubrication system: active tiv thaiv kom muaj teeb meem - ua haujlwm dawb
EWS-440 nta ib qho kev ua kom zoo dual lubrication system uas sib xyaw ua ke ntawm kev quab yuam thiab txaws lubrication 31. Ib qho kev ywj pheej iav roj twj tso kua mis xa cov roj nplua nyeem rau cov ntawv qhia crosshead thiab tag nrho cov bearings tseem ceeb, xyuas kom tsis tu ncua thiab txaus lubrication thiab txias nyob rau hauv tag nrho cov kev khiav hauj lwm tej yam kev mob.
Hydraulic kawg- piv txwv ntawm cov khoom siv siab heev thiab cov txheej txheem tsim khoom
Hydraulic kawg module: Forged raws li lub hauv paus, precision kho raws li tus ntsuj plig
EWS-440 nta ncaj qha- ntws hydraulic kawg module nrog valve- ntawm-valve tsim, forged los ntawm hwm alloy steels xws li 35CrMo lossis 40CrMnMo. Nws cov kev tsim khoom nruj me ntsis ua raws li API 7K cov lus qhia tshwj xeeb, ua raws cov txheej txheem kev kho cua sov (normalizing, quenching, thiab tempering) nrog rau kev kho mob sab hauv. Cov kev ntsuas ua ke no ua tiav cov phab ntsa sab hauv hardness ntawm HB 285-330, nrog cov khoom siv kho tshuab tshaj qhov yuav tsum tau ua. Txhawm rau tiv thaiv cov kua dej corrosive, xaiv cov nickel plating txheej txhim khu kev tiv thaiv corrosion ntawm lub module qhov chaw.
Valve sib dhos: precision, durability thiab yooj yim txij nkawm kev koom ua ke
Lub twj tso kua mis no muaj API #4 specification valve los ua ke, nrog rau ob lub valve lub cev thiab lub rooj zaum forged los ntawm hwm alloy steel thiab kho los ntawm carburizing thiab quenching kom ua tiav qhov tshwj xeeb saum npoo hardness thiab superior sab hauv toughness. Lub tawb- hom valve tsim suav nrog hloov tau ntawm -site polyurethane roj hmab foob.
Cov khoom siv ruaj khov: Ib qho kev xaiv zoo los txo tag nrho cov nqi ntawm cov tswv cuab
Kev xaiv ntawm hnav- cov khoom siv yooj yim tsis yog hais txog tus nqi pib ntawm kev yuav khoom xwb- nws yog qhov kev txiav txim siab zoo uas cuam tshuam ncaj qha rau koj cov peev nyiaj ua haujlwm. Peb muab ntau lub tog raj kheej liner thiab piston xaiv, ua rau koj xaiv qhov zoo tshaj plaws ntawm cov nqi ua ntej thiab ntev -Tsev Nqi Tag Nrho Cov Tswv Cuab (TCO) raws li kev ua haujlwm tshwj xeeb.
Lub tog raj kheej lub tes tsho technology: siab chromium bimetallic thiab zirconia ceramic
Siab -chromium bimetal lub tog raj kheej liner: Cov qauv sib xyaw no sib xyaw ua ke siab - lub zog forged steel sab nrauv lub tes tsho (muab lub zog thiab compressive tsis kam) nrog siab -chromium cam khwb cia hlau puab lub tes tsho (xa tuaj hnav tsis kam). Los ntawm centrifugal casting thiab kev kho cua sov, lub tes tsho sab hauv ua tiav qhov hardness ntawm HRC 60-69. Raws li cov txheej txheem kev ua haujlwm, nws muab kev ua haujlwm ntev li ntawm 800 teev.
Zirconia ceramic cylinder liner: Ib qho kev xaiv zoo tshaj plaws sawv cev rau sab saum toj -tier kev ua tau zoo. Featuring unmatched hardness (HRC 90+), tshwj xeeb hnav thiab corrosion kuj, thiab superior sab hauv phab ntsa tiav, cov khoom siv ruaj khov no muab lub neej kev pab ntau tshaj 4,000 teev-5 txog 10 npaug ntev dua bimetallic lub tog raj kheej liner.
Piston thiab piston pas nrig sib dhos: yug rau kev sib khi zoo meej
Peb muab kev sib koom ua ke sib koom ua ke polyurethane pistons uas muaj kev sib raug zoo siab -kev ua tau zoo polyurethane elastomers rau 45 # steel lossis 40Cr forged hlau cores. Qhov kev tsim qauv no muab qhov tshwj xeeb tsim kua muag tiv thaiv, hnav tsis kam, thiab extrusion tsis kam nyob rau hauv siab - siab txog li 7,500 PSI thiab kub txog 300℃F (149℃).
Lub piston pas nrig yog forged los ntawm 42CrMo siab - lub zog alloy steel thiab tau txais kev kho saum npoo. Ntxiv rau cov txheej txheem nyuaj chrome plating, peb xav kom siv HVOF (High Velocity Oxygen Fuel) tungsten carbide txheej. Compared to chrome plating, HVOF coating offers greater density, higher bonding strength, and near-porosity-free characteristics. Qhov no txhais tau hais tias nws muab kev hnav tsis sib xws thiab kev tiv thaiv corrosion, cuam tshuam rau lub neej kev pab cuam ntawm piston pas nrig thiab lwm yam ntim cov ntsaws ruaj ruaj. Zoo ib yam li cov cylinder ceramic, HVOF-coated piston rods ua tiav cov nqi qis ntawm cov tswv cuab los ntawm kev txo qis txij nkawm thiab NPT, ua rau lawv qhov kev xaiv zoo tshaj plaws rau kev xav tau kev ua haujlwm ib puag ncig.
