CAT C9 Nozzle 330T418062 - Precision Redefined For Common Rail Performance

CovCAT C9 Nozzle (330T418062)tsis yog ib qho kev hloov pauv; Nws yog qhov kawg arbiter ntawm combustion efficiency nyob rau hauv lub C9's HEUI (Hydraulically actuated Electronic Unit Injector) system. Thaum kev lag luam feem ntau txo qhov kev xaiv nozzle mus rau ib qho yooj yim tus lej nrhiav, daim ntawv thov cov ntaub ntawv rau qhov kev hloov pauv tshwj xeeb no nthuav tawm cov toj roob hauv pes nyuaj ntawm kev ua siab ntev thiab cov qauv tshuaj tsuag. Peb qhov kev ntsuam xyuas ntawm daim ntawv teev haum haum (nrog rau cov ntaub ntawv los ntawm235-5261dhau mus20R-8968) qhia tau hais tias lub nozzle yog engineered rau ib tug dav spectrum ntawm C9 muaj thiab marine variants, tshwj xeeb tshaj yog cov uas yuav tsum tau muaj meej txaus txuam los tuav lub ilv tshuav nyiaj li cas ntawm lub hwj chim tso zis thiab emission ua raws li.

Cov ntaub ntawv qhia tau hais tias muaj qhov tseem ceeb ntawm"20R-"thiab"10R-"prefixes ntawm interchanges (piv txwv li,20R-8068, 10R-7221). Hauv Caterpillar lub npe, cov npe "R" feem ntau cuam tshuam rau cov khoom siv rov ua dua lossis hloov kho dua tshiab - tus nqi specifications. Qhov no yog lub ntsiab lus tseem ceeb rau cov kws tshaj lij kev cob qhia: kev txhim kho lub nozzle nrog qhov ntsuas "R" tsis raug tuaj yeem ua rau 3-5% kev sib txawv ntawm cov roj xa khoom, cuam tshuam ncaj qha rau cov lus teb turbocharger thiab EGR txias dua.

Tsis zoo li generic aftermarket options uas vam khom ib zaug xwb -stage orifice design, the330T418062suav nrog Variable Input Torque (VIT) sac ntim tswj. Qhov no geometric feature txo qhov "tuag roj" ntim nyob rau hauv lub nozzle taub. Thaum lub sij hawm pilot txhaj tshuaj -ib qho piv txwv ntawm niaj hnub kev tsheb ciav hlau cov tswv yim - lub hnab ntim me me txhais tau hais tias lub siab nce siab nyob rau hauv lub cev txhaj tshuaj.

For the CAT C9, which operates at injection pressures typically ranging from 23,000 to 28,000 psi, the nozzle's metallurgical composition is paramount. This component utilizes a high-grade martensitic stainless steel, nitrided to a surface hardness of >1100 HV. Qhov kev kho mob no ua kom paub tseeb tias cov npoo ntawm qhov muag muag khaws lawv cov hydraulic txoj kab uas hla kev ncaj ncees txawm tias tom qab 10, 000+ teev ntawm kev thauj mus los. Qhov kev sib tshuam ncaj qha nrog ib feem10R-9002underscores nws compatibility nrog kho tshiab injector lub cev geometries pom nyob rau hauv Tier 3 emission standard engines.

Txhawm rau kom txaus siab rau kev tsim vaj tsev tom qab lub nozzle, ib qho yuav tsum tau saib ntawm qhov ntws tus nqi nkhaus. Kev ywj pheej lub rooj ntev zaum- cov ntaub ntawv kuaj pom tias covCAT C9 330T418062muab qhov kam rau ua ntawm +/- 2.5% ntawm tag nrho cov hlab ntsha.

Parameter	Specification	Kev cuam tshuam rau lub cav

Rov qab Los	< 8 ml/min	Txhim kho txoj kev tsheb ciav hlau siab ruaj khov thaum tsis ua haujlwm

Cov ntaub ntawv hla - siv nrog cov lej zoo li293-4072thiab267-9710qhia tias lub nozzle zaum hauv pawg "siab-altitude" calibration. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov neeg ua haujlwm hauv thaj chaw uas muaj qhov sib txawv ntawm cov huab cua sib txawv, vim tias lub nozzle cov qauv tshuaj tsuag tau them rau cov pa oxygen qis dua, tiv thaiv "dawb pa luam yeeb" txias pib.

Ib qho ntawm qhov tsis pom zoo tshaj plaws ntawm kev hloov lub nozzle yog pop-off siab (los yog qhib siab) hloov kho. Rau C9 platform, phau ntawv qhia kev pabcuam feem ntau qhia txog qhov chaw zoo li qub ntawm3100 psi uathiab3300psi ua. Txawm li cas los xij, nrog rau330T418062, peb pom zoo kom nce 2% shim thickness yog tias koj hloov ib chav tsev nrog cov laus238-8092siv. Qhov kev hloov kho no suav nrog kev hnav hauv lub plunger injector, kom ntseeg tau tias lub sijhawm ua haujlwm hluav taws xob hluav taws xob (tswj los ntawm ECM) ua kom zoo nrog cov neeg kho tshuab hydraulic qeeb.

Nco ntsoov: Ib txwm hla- siv lub 10R/20R ua ntej kom paub meej tias daim ntawv qhia kev ntsuas roj raug raug.

Q1: Puas yog nws tsim nyog los hloov tag nrho rau lub nozzles ib txhij, lossis kuv tuaj yeem hloov ib qho xwb?
Muab rau CAT C9 qhov kev cia siab ntawm "Trim Codes" rau kev kho cov roj kom muaj nuj nqis, hloov ib lub nozzle nrog cov pab pawg sib txawv (xws li kev sib xyaw ua ke.387-9437nrog a387-9431) yuav ua rau "Cylinder Contribution" txhaum cai. ECM kuaj pom qhov sib txawv ntawm qhov sib txawv; mismatched ntws ua rau inconsistent txhaj koob tshuaj. Peb pom zoo kom hloov tag nrho cov teeb tsa kom muaj lub zog sib npaug thiab tiv thaiv EGR txias ntsaws vim tsis tiav combustion.

Q2: Qhov no lub taub hau ua li cas Biodiesel blends (B20 thiab siab dua)?
Cov330T418062nta lub pob zeb diamond-zoo li cov pa roj carbon (DLC) txheej ntawm rab koob qhia, muab kev tiv thaiv lubrication zoo dua. Txawm li cas los xij, qhov siab dua viscosity ntawm biodiesel tuaj yeem ua rau kom qeeb hydraulic. Peb qhia kom txo cov sijhawm txhaj tshuaj tiv thaiv los ntawm 2 degrees ntawm ECM (yog tias tso cai) txhawm rau txhawm rau txhawm rau ua kom lub zog qeeb qeeb, tiv thaiv lub tog raj kheej ntau dhau (lub siab tshaj plaws hluav taws xob) uas tuaj yeem ua rau qaug zog ua ntej lub taub hau gasket.

Q3: Dab tsi yog qhov pom pom tias lub nozzle tshwj xeeb (330T418062) ua tsis tiav, ib sab ntawm cov pa luam yeeb dub?
Cov tsos mob tshwj xeeb ntawm C9 nozzle tsis ua haujlwm yog "torpedo" suab nrov-ib qho hlau rauj thaum lub sijhawm txhaj tshuaj tseem ceeb. Qhov no tshwm sim thaum lub rooj zaum nozzle hnav tsis tu ncua, tso cai rau combustion gases intrude rau hauv lub injector roj gallery. Koj tseem tuaj yeem pom qhov "Fuel Dilution" nce ntxiv hauv cov roj cav, qhov txawv ntawm qhov tsis hnov ​​​​tsw ntawm lub dipstick, uas peb xav txog qhov tseem ceeb thaum ntxov.

Q4: Kuv puas tuaj yeem siv 330T418062 los txhim kho kuv lub cav qub 3126B?
Thaum lub cev lub nozzle yuav haum, lub hydraulic actuation siab ntawm C9 (txog 3,000 psi roj siab) yog ho siab tshaj li 3126B. Txhim kho lub nozzle nyob rau hauv qis dua - lub zog siab yuav ua rau "Nozzle Sticking" vim tias qhov kev txhaj tshuaj qeeb dhau, ua rau qhov tsis zoo thiab tsis zoo. Nws yog nruj me ntsis engineered rau C9 HEUI twj tso kua mis architecture.

Q5: Vim li cas ntu 20R-8060 tau teev ntau zaus hauv OEM cov ntaub ntawv?
Qhov nthuav dav ntawm20R-8060thiab cov ntaub ntawv zoo sib xws "20R" qhia tias qhov no yog "Core Charge" khoom. Nws txhais tau hais tias Caterpillar suav tias qhov no yog qhov siab - cov khoom muaj nqis rov ua dua tshiab. Thaum yuav khoom330T418062, peb qhov tseem ceeb hauv qhov kev hloov pauv tseem ceeb no, ua kom peb lub tsev ua raws li cov kev txwv nruj nruj (0.0015" - 0.0020" tshem tawm) xav tau rau daim ntawv pov thawj reman.

Q6: Puas yog "Pop Pressure" cuam tshuam rau cov roj rov qab zoo li qub?
Yog lawm. Lub siab qis qis dua li teev rau lub nozzle ua rau qhib ua ntej, ua rau "Rov Qab Los" (rov qab roj) txog li 15%. Qhov no nce cov roj kub hauv lub tank, txo qhov ua kom txias ntawm cov roj system. Peb calibrate txhua chav nyob rau qhov siab dua spec xav tau rau kev siv267-9717thiab293-4073kom ntseeg tau tias tus nqi rov qab nyob li ntawm 6-10 ml / min pib.
