10R-1001 Roj Txhaj Pump - OEM-Spec High-Pressure Plunger Assembly For Caterpillar 3412 Series

Hauv 12-lub tog raj kheej lub cav hnyav zoo li Caterpillar 3412, txhua lub twj tso kua mis yuav tsum xa cov roj ntim ntim hauv lub qhov rais nqaim crankshaft. Cov10R-1001(Caterpillar OEM siv) tsis yog lub tshuab hluav taws xob siab xwb- nws txhais tau tiastus nqi - ntawm - tso tawmprofile uas ncaj qha cuam tshuam combustion phasing. Lub twj tso kua mis no tswj hwm ob qho tib si pib- ntawm- kev xa khoom (ntawm nws lub cam-tsav plunger) thiab qhov kawg - ntawm - kev xa khoom (ntawm cov tswj khib nyiab thiab cov chaw nres nkoj spill), zoo encoding lub sij hawm txhaj tshuaj rau hauv cov tshuab geometry. Rau cov neeg tsav nkoj thiab cov neeg tsim kho dua tshiab, xaiv lub twj tso kua mis tom qab uas rov ua cov yam ntxwv ntawm lub siab-lift-lub sij hawm yog qhov tseem ceeb rau kev tuav lub tog raj kheej - rau - lub tog raj kheej sib npaug thiab tsis txhob haus luam yeeb dawb lossis khob thaum pib txias.

Lub 10R-1001 ntiav atas li -stroke, variable-spilltsim nrog cov nram qab no metrology tseem ceeb:

Plunger txoj kab uas hla:10.0 hli (nominal) nrog cov av tawv tawv (HRC 62–64) thiab micro- polished tiav (Ra Tsawg dua lossis sib npaug li 0.1 μm) kom txo cov pa tawm.

Ua haujlwm stroke:8.5 mm (txiav txim siab los ntawm cam lobe nqa, tsis yog - kho tau).

Spill Port geometry:helical ntug machined ntawm lub plunger, ua kom muaj kev sib raug zoo ntawm txoj haujlwm khib thiab xa cov roj ntim (0-550 mm³ / stroke ntawm ntsuas ceev).

Tswj khib mus ncig:14 hli tag nrho, nrog lub zog tawm tswv yim uas cuam tshuam nrog tus tswv xeev txuas. Ib qho 1 hli racks hloov pauv hloov roj los ntawm kwv yees li 40 mm³ / stroke- tseem ceeb rau kev kho qhov tsis muaj zog thiab cov pa taws tsis ntev.

All clearance fits (plunger-to-barrel: 0.003–0.006 mm) are verified with air-gauging during remanufacturing, ensuring volumetric efficiency >92% ntawm 1,500 rpm.

Cov kev ntsuam xyuas lub rooj zaum tau ua los ntawm Bosch EPS 100 qhov ntsuas qhov muag pom cov ntaub ntawv siv hauv qab no rau 10R-1001 (roj kub 40 degree, ISO 4113):

Ceev (rpm)	Rack Position (mm)	Kev xa khoom (mm³ / stroke)	Peak Txhaj Siab (MPa)	Lub sijhawm txhaj tshuaj (degree A)
800 (tsis muaj)	6.0	85	38	12.5
1,500 (qhov siab tshaj plaws torque)	10.5	280	92	18.2
2,200 (nyob)	12.0	420	78 (tej zaum vim muaj kev txwv qhov ncauj)	21.5
2,450 (hli)	13.5 (Txoj cai)	510 (max)	72	24.0

A critical observation: pressure rises with speed up to 1,500 rpm, then declines above 2,000 rpm due to increased spill leakage-a signature of healthy plunger clearance. Deviations >± 5% los ntawm cov nqi no qhia txog kev hnav sab hauv lossis tsis raug plunger -rau - chim sib xws.

Lub 10R-1001 yog hloov ncaj qha rau Kab ntsig 3412 variants siv hauv:

Marine propulsion(nruam thauj khoom, dej ntsev txias, nquag qis -idle maneuvers)

Gen- teeb pob(50/60 Hz prime power, sudden step-load hloov)

Hnyav- cov tsheb thauj khoom hnyav(tawm -cov tsheb loj, 40+ tuj payloads)

Industrial compressorsthiabtwj tsavyuav tsum tsis tu ncua torque ntawm 1,800 rpm

Txhua daim ntawv thov xav tau tshwj xeeb tus tswv xeev teeb tsa- lub twj tso kua mis sab nraud lub tog raj kheej thiab lub caij nplooj ntoos hlav- loaded idle damper yog adjustable rau tailor droop (3–8%) thiab overshoot (tsawg dua los yog sib npaug li 5% ntawm rated ceev).

Peb lub twj tso kua mis 10R-1001 tau rov ua dua tshiab siv cov kab ntsig qub qub (tshwj xeeb los ntawm 10R-1001 stamp) thiab dhau los ua 14-kauj ruam kev kho dua tshiab:

Ultrasonic tuntawm tag nrho cov sab hauv galleries.

Dimensional soj ntsuamntawm lub thoob bore, plunger OD, thiab tswj lub tes tsho ID (3D laser scanning).

Xaiv haumntawm cov tshiab plunger khub (qib A lossis B) los kho qhov qub tshem tawm.

Hloovntawm kev xa khoom valve, caij nplooj ntoos hlav, thiab cov ntsaws ruaj ruaj nrog Viton® siab -kub sib txuas.

Siab- kuajtus tswv tsev vaj tse rau cov dej ntws mus txog 1.5 MPa.

Dynamic calibrationntawm lub rooj zaum xeem-cov ntaub ntawv thiab kho tag nrho- thauj khoom thiab tsis siv neeg xa khoom siv shim hloov kho ntawm lub caij nplooj ntoos hlav preload.

Daim ntawv xeem kawg(serialized) qhia txog kev xa khoom tiag tiag, lub sijhawm ua ntej, thiab xa rov qab - leakage ntawm tsib lub ntsiab lus nrawm - lav kom phim OEM txwv tsis pub dhau ± 2%.

Tag nrho cov twj kho kho tau raug xa nrog 12-hli warranty npog cov khoom tsis xws luag thiab calibration drift.

Q1: Kuv tuaj yeem txheeb xyuas tau li cas tias lub twj tso kua mis 10R-1001 kuv tau txais yog OEM tiag thiab tsis yog cuav?
Tshawb xyuas cov casting - cov units tiag tiag muaj qhov tsa "10R-1001" thiab hnub code (xws li 3A21) ntawm lub flange. Tsis tas li ntawd, tus xa khoom valve tuav nqa lub laser -etched serial tooj. Peb cov twj remanufactured tuaj nrog traceable calibration daim ntawv pov thawj cross-referenced rau tus thawj casting tooj.

Q2: Puas yog lub twj tso kua mis xav tau cov roj nplua nyeem tshwj xeeb thaum lub sijhawm teeb tsa dua li cov roj nws tus kheej?
Peb pom zoo kom siv ib txheej nyias ntawm cov roj cav huv rau hauv phau ntawv qhia plunger thiab O-rings thaum lub sij hawm sib dhos kom tsis txhob qhuav- khawb thaum pib. Tsis txhob siv roj, vim nws tuaj yeem ua rau cov khoom tawg.

Q3: Dab tsi yog cov cim qhia tias lub twj tso kua mis plunger thiab lub thoob tau hnav dhau qhov kev khaws cia?
On the test bench, if the delivery volume at rated speed drops by >8% piv rau daim ntawv qhia sivthiabqhov xa rov qab xa tawm ntau dua 15% ntawm cov khoom ntim tawm, qhov kev tshem tawm tau dhau 0.012 hli- xav tau cov txheej txheem tshiab. Peb muab cov plunger tshiab - chim khub ua cov kab sib cais.

Q4: Lub twj tso kua mis no puas tuaj yeem siv rau ntawm lub cav 3412 nrog qhov sib txawv camshaft profile (xws li marine piv rau kev lag luam)?
Lub twj tso kua mis lub plunger stroke yog txiav txim los ntawm lub cav cam, tsis yog lub twj tso kua mis nws tus kheej -yog li 10R-1001 haum rau tag nrho 3412 blocks. Txawm li cas los xij, tus tswv xeev springs thiab idle ntswj yuav xav tau kev rov ua kom zoo dua qub kom haum rau qhov tshwj xeeb droop nkhaus ntawm koj daim ntawv thov. Peb muab kev pabcuam rau tus tswv xeev raws li qhov kev thov.

Q5: Puas yog nws tuaj yeem kho qhov max roj ntsia hlau yam tsis muaj kev cuam tshuam lub twj tso kua mis?
Yog-muaj lub xauv sab nraud thiab ntsia hlau rau ntawm tus tswv tsev nyob. Tig nws clockwise nce puv -load roj los ntawm kwv yees li 8 mm³/stroke ib lub hlis twg tig. Txawm li cas los xij, peb tawm tswv yim tawm tsam qhov kev hloov kho ntawm thaj chaw tshwj tsis yog tias koj muaj kev nkag mus rau lub rooj sib tw xeem; Kev teeb tsa tsis raug ua rau muaj ntau dua - roj thiab tso pa ntau dhau.

Q6: Kuv yuav khaws cov khoom seem 10R -1001 lub twj tso kua mis li cas rau lub sijhawm ntev (ntau tshaj 1 xyoos) yam tsis muaj cov ntsaws ruaj ruaj?
Tshem tawm tag nrho cov roj, sau nrog corrosion- txwv tsis pub roj (xws li Plhaub Ensis), tig lub flange ib ntus kom rov faib cov roj nplua nyeem, thiab khaws cia hauv qhov chaw qhuav. Cov khoom siv yas hau npog npog tag nrho cov chaw nres nkoj kom tsis txhob muaj plua plav nkag.

 

Txhawm rau ua kom koj qhov kev yuav khoom tau yooj yim thiab yooj yim, peb muab ntau yam kev xaiv them nyiaj ruaj ntseg:

Peb nyob ntawm no los ua kom koj cov txheej txheem xaj kev txhawj xeeb-dawb - xaiv txoj kev them nyiaj uas ua haujlwm zoo tshaj rau koj!
