High-Precision Common Rail Nozzle P2894920|Hwm Atomizer Rau Cummins XPI / ISX15 Systems

Nyob rau hauv lub ntiaj teb xav tau ntawm ntev -haul fleet tu thiab industrial diesel cav manufacturing, roj xa tsis raug txiav txim los ntawm yooj yim ntim- nws yog ntsuas nyob rau hauv micro- thib ob execution thiab micro- millimeter tsuag raug. Raws li cov chav kawm -8 hnyav- lub tsheb ua haujlwm tau ntsib cov cheeb tsam hauv cheeb tsam emissions ciam teb thoob plaws North America thiab Europe, cov khoom siv roj tom qab ib txwm muaj cov kua dej tsis sib haum, kev xav tsis thoob, thiab tsis sib xws hydro-erosion. Cov kev tsis sib haum me me no ua rau muaj qhov nce tam sim ntawd hauv cov khoom siv hluav taws xob diesel particulate lim (DPF) rov tsim dua tshiab, lub hauv paus piston crown overheating, thiab poob rau hauv tag nrho cov roj siv hluav taws xob.

Lub luag haujlwm hnyav -P2894920common rail nozzle stands raws li ib tug ncaj qha technological tov engineered rau qhov huab ib puag ncig ntawm lub Cummins eXtended Performance Injection (XPI) siab -siab common rail platform. Los ntawm kev ua kom zoo ntawm cov qauv sib npaug ntawm cov koob hauv hydraulic nqa thiab lub siab - tawm qhov tawm ntawm qhov chaw, cov khoom siv no hloov cov roj siab rau hauv ultra- zoo, huab cua kub heev. Rau cov kws tshaj lij kev pabcuam kho tsheb, cov neeg tsim khoom siv cav, thiab cov neeg xa khoom xa tuaj, kev sib koom ua ke no lub tshuab ua haujlwm zoo khaws cia lub sijhawm tseem ceeb ntawm lub cav, sib npaug lub tog raj kheej lub zog faib, thiab tiv thaiv cov khoom siv hluav taws xob tsis zoo tom qab kev thauj mus los tsis tu ncua.

Hydraulic discharge profile ntawm lubP2894920Cov qauv nozzle tau raug ntsuas raws li qhov tshwj xeeb hnyav- tshem tawm cov khoom lag luam tawm, tshem tawm qhov txaus ntshai lub tog raj kheej ntsuas qhov teeb meem tshwm sim nrog kev sib tw thoob ntiaj teb tom qab muag:

Ntawm -Kev Loj Loj:Cummins ISX15 (CM2250, CM2350 configurations) thiab EPA10 / EPA13 / EPA17 raws txoj kab -haul tsheb laij teb platforms.

Tawm -Kev loj & Lub zog muaj zog:Cummins QSX15 Tier 4 Kev ua liaj ua teb zaum kawg, cov khoom siv mining hnyav, thiab ntau -megawatt standby generator systems.

Core Injector Assembly Support:Tsim los ua lub hauv paus kev tsim kho tshiab rau cov hwm XPI kev sib koom ua ke ntawm cov tsheb ciav hlau injector hauv qab cov lej2894920, 28949 20 tzx, 28949 20 XIV, thiab5579415.

 

 

Hauv kev ua haujlwm siab ntsuas ntawm2,600 ib, cov roj nyob rau hauv ib qho system XPI coj tsawg dua li cov qauv kua thiab ntau dua li lub dav hlau kinetic erosive. Standard nozzle configurations tawm tsam nrog cov roj cavitation nyob rau hauv lub ntse ntug ntawm lub inlet qhov. Qhov no tsim micro- npuas uas tawg ua rau hnyav, tsim me me shockwaves uas nws thiaj li ua rau lub rooj zaum koob thiab ua rau roj to.

Internal passages ntawm lubP2894920siv cov txheej txheem hydro-eroded rounding txheej txheem ntawm cov npoo sab hauv ntawm cov tshuaj tsuag qhov. Los ntawm ua ntej - smoothing cov dej nkag nkag, lub nozzle drastic txiav rov qab rau hauv cov kua shear thiab cavitation. Cov kauj ruam no ua kom ruaj khov, tsis hloov pauv lub kaum ntse ntse hla ntau pua txhiab lub luag haujlwm, tiv thaiv cov roj-dribbling teeb meem uas ua rau cov pa roj carbon ntim rau ntawm lub taub hau.

 

 

Rebuilding common rail Cheebtsam xav kom huv si huv si -chav txheej txheem thiab cov neeg kho tshuab ua kom meej meej ua hauj lwm mus ntev:

Strict Contamination Isolation:Siab -siab cov khoom siv tsheb ciav hlau tsis tuaj yeem zam cov plua plav microscopic. Ua tag nrho cov nozzle swaps hauv qhov chaw ua haujlwm huv si. Ib qho me me raws li huab cua sib txawv2 micronsdai rau hauv phau ntawv qhia nozzle tuaj yeem ua rau rab koob tam sim ntawd.

Nozzle Cap Nut Torque txheej txheem:Thaum sib dhos lub nozzle rau hauv lub cev txhaj tshuaj, ua raws li lub Hoobkas ntau- txheej txheem nruj. Thaum kawg torque yuav tsum tau so raws nraim ntawm qhov kev qhia tshwj xeeb. Tshaj -tightening risks warping the needle sleeve guide, which slows down the injector's response time.

Injector Terminal Ntxuav:Ua ntej zawv zawg lub reassembled injector rau hauv lub tog raj kheej lub taub hau chamber, xyuas kom meej lub ntsej muag tooj liab crush lub ntsej muag yog huv si zoo kawg nkaus. Txhua sab laug- tshaj cov pa roj carbon monoxide yuav qaij lub injector me ntsis, pov tawm ntawm qhov kev npaj tshuaj tsuag lub kaum sab xis ntawm lub piston lub tais geometry.

 

Q1: P2894920 nozzle tsim ncaj qha txhim kho lub tsheb DPF li cas?

A1:Thaum lub nozzle poob qis, nws feem ntau cia roj dribble tawm, ua rau tsis tiav combustion thiab ntau heev soot. CovP2894920tswj cov roj ntse txiav-offs thiab nplua atomization. Qhov kev kub hnyiab no txo ​​qhov ntim ntawm cov kua qaub mus rau hauv txoj kev tso pa tawm, ncab tawm lub sijhawm ntawm DPF kev tsim dua tshiab.

Q2: Puas yog P2894920 nozzle cross-tshaj nrog cov laus uas tsis yog-XPI Cummins ISX roj platforms?

A2:Tsis yog. Lub nozzle no tau ua kom meej meej nyob ib puag ncig ntawm qhov siab -flow dynamics thiab ultra-siab siab theem (2,600 ib) ntawm Cummins XPI common rail network. Nws yuav tsis ua haujlwm zoo hauv cov laus dual - nyiaj siv ua haujlwm -cam HPI-TP unit injector setups.

Q3: Cov khoom siv tseem ceeb li cas thiaj li tso cai rau lub taub hau no kom muaj sia nyob sib txawv lossis qis dua -lubricity ultra- qis sulfur diesel (ULSD)?

A3:Daim ntawv qhia koob thiab lub hnab tsho zaum tau dhau los ua ntau yam - txheej txheej nitriding. Qhov kev kho no ntxiv cov txheej txheem ruaj khov uas tiv taus qhov hnav thiab ua rau lub qhov txhab, tiv thaiv cov khoom siv txawm tias siv cov roj qhuav los yog qis dua -lubricity ULSD fuels.

Q4: Kuv lub khw kho hluav taws xob puas tuaj yeem lees paub qhov kev teeb tsa nozzle siv cov qauv ntsuas ntsuas?

A4:Yog lawm. Lub cev tsim thiab ntws specs ntawm lub nozzle kab mus zoo kawg nkaus nrog kev lag luam - qauv kev tsheb ciav hlau calibration khoom, suav nrog Bosch EPS units thiab Dieselogic NEO platforms. Qhov no tso cai rau kev txhaj tshuaj meej meej-rau- kev tshuaj ntsuam xyuas kev txhaj tshuaj ua ntej kev teeb tsa lub cav zaum kawg.

Q5: Dab tsi yog qhov laj thawj tseem ceeb ntawm cov qauv tshuaj tsuag ntxov ntxov ntawm qhov hnyav -cov lus qhia XPI?

A5:Qhov ua rau yog cov roj paug sib xyaw nrog qhov tsis zoo nozzle cap txiv ntoo torque. Microscopic particles khawb qhov zoo ntawm daim ntawv qhia koob, thaum dhau -torquing lub cev warps lub bore. Ob qho teeb meem ua rau rab koob rub thiab hloov pauv cov qauv tshuaj tsuag.
