201-4202 Fuel Injection Pump – High-Torque Rise Variant For Caterpillar 3412 Industrial & Marine Engines

Nyob rau hauv Caterpillar 3412 roj system portfolio, lub 201-4202 OEN sawv cev rau ib tug tshwj xeeb calibration ceg-tsis yog ib tug txawv casting tooj, tab sis lub twj tso kua mis tuned rausiab zog torque (15-20%)thiabtxhawb nqa qis - nrawm nrawmpiv rau tus qauv 10R-1001. Thaum ob leeg sib koom tib lub 10 hli plunger txoj kab uas hla thiab lub thoob geometry, 201-4202 suav nrog kev hloov kho rack cam profile thiab lub zog xa tawm valve caij nplooj ntoos hlav, uas ncua sij hawm ntuav ntawm qhov chaw qis qis. Qhov kev hloov pauv hloov maj mam ua rau cov roj xa hluav taws xob uas txhawb nqa lub zog ua kom maj mam tsim- nce siab dhau qhov kev tawm tsam thawj zaug - zoo tagnrho rau cov nkoj nkoj nkoj thiab cov gen-sets nrog siab inertia flywheels. Rau cov kws tshaj lij, kev paub txog qhov sib txawv no yog qhov tseem ceeb: kev txhim kho 201-4202 hauv daim ntawv thov lub zog siab tshaj plaws (xws li cov tsheb thauj khoom) yuav ua rau qeeb qeeb, thaum siv 10R-1001 hauv daim ntawv thov marine tuaj yeem tsim cov pa luam yeeb dub ntau dhau thaum lub sijhawm hloov pauv.

Lub 201-4202 tuav tib lub mounting flange, tsav iav suab, thiab high-pressure qhov hluav taws xob xov (M22x1.5) raws li tag nrho cov 3412 twj, xyuas kom meej lub cev interchangeability. Txawm li cas los xij, cov ntaub ntawv tseem ceeb sab hauv txawv:

Parameter	201-4202	10R-1001 (rau kev siv)
Plunger txoj kab uas hla	10.0mm (ib yam)	10.0 hli
Ua haujlwm stroke	8.5mm ib	8.5mm ib
Tswj khib tag nrho mus ncig	16.5mm (ntxiv)	14.0mm 3
Max xa khoom @ ntsuas ceev	480 mm³ / stroke @ 2,300 rpm	420 mm³ / stroke @ 2,200 rpm
Kev xa tawm valve qhib siab	28 MPa ± 0.5	25 MPa ± 0.5
Tus tswv xeev poob chaw (Factory)	6% (kho tau 3-10%)	8%

Qhov kev mus ncig ntev dua tso cai rau lub twj tso kua mis kom ntsuas roj ntxiv thaum tus tswv xeev xav kom puv - thauj khoom ntawm qis rpms - txhim kho torque thaub qab yam tsis muaj pa taws ntau tshaj - txwv huab cua / roj piv. Qhov qhib siab ntawm qhov xa khoom tuaj yeem txhim kho siab -siab kab nthwv dej propagation, txo cov kev txhaj tshuaj ncua los ntawm kwv yees li 0.3 ms ntawm 1,200 rpm, uas txhais tau hais tias muaj kev cuam tshuam ntau dua.

Cov ntaub ntawv pov thawj calibration (ISO 4113 roj, 40 degree) rau 201-4202 qhia tus yam ntxwvhumpnyob rau hauv kev xa khoom nkhaus:

Ntawm1,000 rpm(Idle Governor engagement): 90 mm³/stroke.

Ntawm1,400 rpm ib(lub ncov torque point): 350 mm³ / stroke - qhov no yog 25% siab dua 10R-1001 ntawm tib txoj haujlwm khib.

Ntawm1,800 rpm ib: kev xa khoom poob rau 310 mm³ / stroke vim qhov chaw nres nkoj lub sijhawm ua ntej.

Ntawm2,300 rpm ib(rated): 480 mm³ / stroke (siab tshaj plaws).

Qhov no tsis yog -linear profile yog txhob txwm tsim tawm: lub twj tso kua mis muab cov roj ntxiv raws nraim hauv qhov chaw uas lub cav xav tau nws los kov yeej lub kiv cua lossis compressor surge, thaum tapering ntawm qhov nrawm dua los tiv thaiv overspeeding. Tus tswv xeev reacts load hloov ntawm aflyweight-thiab- caij nplooj ntoos hlavmechanism-lub 201-4202 siv lub caij nplooj ntoos hlav tsis muaj zog, uas ua rau lub droop band widens thiab muab lub cav "softer" xav thaum lub sij hawm docking maneuvers.

Lub twj tso kua mis no yog lub Hoobkas - qhia tshwj xeeb rau:

Kab ntsig 3412E marine propulsion(cov dej num txuas mus ntxiv, tsau- lub suab nrov nrov) - torque nce ntxiv rau txoj cai kiv cua (torque ∝ rpm²).

Industrial compressor pob khoom(piv txwv li, Atlas Copco, Ingersoll Rand) xav tau lub zog torque ntawm 1,200-1,800 rpm.

Gen- teeb tsa rau 50 Hz prime zog(1,500 rpm) - lub twj tso kua mis ruaj khov ntawm qhov ceev kom ntseeg tau qhov voltage / zaus teb hauv ISO 8528-5 txwv.

Rau tawm - tsheb loj, Kab ntsig feem ntau qhia txog 10R-1001; Kev siv 201-4202 hauv cov ntawv thov no yuav xav tau kev rov ua kom rov zoo ntawm lub cav roj txwv cov ntsia hlau thiab tuaj yeem ua rau cov pa luam yeeb dub ntawm qhov siab siab vim muaj kev sib xyaw ntau dua. Yog li ntawd, nco ntsoov xyuas lub cav serial tooj ua ntej (piv txwv li, 4SJ, 5SN) nrog rau cov khoom siv phau ntawv.

Peb 201-4202 remanufactured twj tso kua mis ua tib yam nruj 14-kauj ruam raws tu qauv raws li 10R-1001, nrog rau ib qho ntxivdynamic ntsuaskauj ruam rau kev tswj cov khib nyiab sib dhos-vim lub khib nyiab ntev dua yog qhov cuam tshuam rau kev co-induced hysteresis. Peb siv:

Ultrasonic tunrog cov tshuaj chelating kom tshem tawm cov kua roj vanish sab hauv yam tsis tawm tsam cov tawv tawv.

Selective haum plunger / chim khubqib A (clearance 0.003–0.004 mm) kom rov ua kom lub cev muaj zog.

Kev xa khoom valve lappingkom ua tiav qhov qhib siab (28 MPa) siv cov nitrogen- tswj cov khoom siv.

Governor calibrationntawm lub rooj zaum rov ua dua tshiab simulating ob qho tib si ramp load thiab cov kauj ruam load profiles - kaw rau hauv daim ntawv pov thawj 6-point calibration.

Txhua lub twj tso kua mis yog khiav -nyob rau hauv rau 30 feeb nyob rau hauv tag nrho - load tej yam kev mob kom stabilize lub caij nplooj ntoos hlav poob lawm, tom qab uas peb re- ntsuas lub khib- mus rau - xa tawm linearity. Daim ntawv tshaj tawm zaum kawg suav nrog qhov ntsuas lub zog ntsuas- nce qhov ntsuas (qhov sib piv ntawm kev xa khoom ntawm 1,400 rpm txog 1,800 rpm), ua kom nws poob hauv 1.15–1.25 raws li OEM spec.

Q1: Puas yog 201-4202 hloov ncaj qha rau 10R-1001 ntawm tag nrho 3412 lub cav?
Lub cev muaj, tab sis functionally tsis. Kev ntsuas cov roj xa tawm txawv- hloov 10R-1001 nrog 201-4202 yam tsis tau kho tus tswv xeev yuav ua rau muaj roj ntau dhau ntawm qhov nruab nrab, muaj peev xwm tshaj qhov txwv tsis pub haus luam yeeb. Peb pom zoo kom sab laj lub cav cov ntawv xov xwm kev pabcuam rau tus lej raug raws li daim ntawv thov.

Q2: Kuv yuav ua li cas thiaj paub qhov txawv ntawm 201-4202 casting los ntawm chav tsev cuav?
Caterpillar castings tiag tiag muaj qhov sib txawv "201-4202" tus naj npawb tau tsa ntawm lub flange, nrog rau peb- tsab ntawv hnub code (piv txwv li, "CJG") thiab laser-etched bar code ntawm tus tswv xeev npog. Peb cov twj remanufactured kuj muaj xws li ib tug tamper-pov thawj foob hla lub calibration ntsia hlau.

Q3: Dab tsi yog qhov siab tshaj plaws roj kub lub twj tso kua mis tuaj yeem tiv taus thaum ua haujlwm tas mus li?
Lub twj tso kua mis yog ntsuas rau roj inlet kub txog li 70 degree. Saum toj no, cov viscosity poob, ua rau sab hauv to thiab txo qhov ntim ntawm kwv yees li 0.5% ib 5 degree. Peb pom zoo kom txhim kho cov roj txias yog tias lub cav ua haujlwm hauv huab cua sov.

Q4: Kuv puas tuaj yeem kho lub zog torque -nce tus yam ntxwv los ntawm kev hloov tus tswv xeev springs?
Yog lawm-peb muab cov khoom siv caij nplooj ntoos hlav (muag nyias) uas hloov qhov droop thiab torque nce. Txawm li cas los xij, qhov no yuav tsum muaj lub rooj ntev zaum rau kev ntsuas kom zoo; Kev hloov kho ntawm thaj chaw yam tsis muaj kev ntsuas feem ntau ua rau tsis ruaj tsis khov mus yos hav zoov lossis ncua sij hawm lees txais.

Q5: Puas yog lub twj tso kua mis xav tau qhov tshwj xeeb siab - txoj kab siab ntev los tswj lub sijhawm txhaj tshuaj?
Tus thawj 3412 siv cov kab sib npaug ntawm qhov ntev (kwv yees li 800 hli) los xyuas kom meej lub sijhawm sib xws ntawm lub tog raj kheej. Yog tias koj hloov ib lub twj tso kua mis xwb, tswj cov kab uas twb muaj lawm. Yog tias txhim kho cov txheej txheem tag nrho, siv cov kab uas muaj qhov sib npaug nrog txoj kab uas hla (2.0 mm) thiab ntev kom tsis txhob voj voog - mus rau - lub voj voog hloov pauv.

Q6: Dab tsi yog qhov kev pab cuam lub neej ntawm remanufactured 201-4202 twj tso kua mis nyob rau hauv ib txwm marine lub luag hauj lwm?
Nrog cov roj pom zoo (tsawg dua lossis sib npaug li 10 µm) thiab kev saib xyuas roj / dej tsis tu ncua, lub twj tso kua mis feem ntau kav ntev txog 8,000-10,000 teev ua ntej xav tau lub plunger / chim hloov. Lub tshuab xa khoom valve tuaj yeem tsis muaj zog ua ntej, nyob ib puag ncig 6,000 teev-peb suav nrog cov khoom siv hloov pauv hauv peb cov khoom siv kho dua tshiab.
