0R-2236 Fuel Injection Pump - Precision-Matched For Caterpillar 3412 Nruam-Lub Luag Haujlwm & Gen-Set Daim Ntawv Thov

Txhua lub twj tso kua roj tso tawm ib qho kev ua haujlwm siab -ib qho "tus ntiv tes" tshwj xeeb uas txhais tau tias nws cuam tshuam li cas nrog lub cav qhov torsional dynamics thiab combustion stability. Cov0R-2236(Caterpillar OEN) yog tshwj xeeb calibrated rau cov ntawv thov kom unwavering roj xa nyob rau hauv tas li hluav taws xob los yog hydraulic loads, qhov twg txawm ib tug 2% sib txawv nyob rau hauv txhaj ntim ib lub voj voog yuav txhais tau rau hauv ntsuas zaus drift los yog voltage sag. Tsis zoo li nws cov kwv tij (10R-1001 thiab 201-4202), uas hais txog qhov siab tshaj plaws torque lossis cov lus teb tsis ntev, 0R-2236 tseem ceeb.isochronous kev xa khoom linearityhla tag nrho cov kev khiav hauj lwm band los ntawm 1,200 mus rau 2,200 rpm-ua rau nws qhov kev xaiv zoo tshaj plaws rau prime-power gen-sets thiab nruam-duty industrial drives.

0R-2236 sib koom tib lub 10.0 hli plunger txoj kab uas hla thiab 8.5 hli zoo stroke raws li tag nrho cov 3412 twj, tab sis qhov tseem ceeb sab hauv qhov sib txawv kom ua tiav nws lub tiaj tus xa khoom profile:

Parameter	0R-2236	201-4202 (torque-nce)	10R-1001 (tus qauv)
Tswj khib taug kev	14.0mm (ib yam li 10R-1001)	16.5mm 3	14.0mm 3
Kev xa tawm valve qhib siab	30MPa ± 0.5 hli	28 MPa	25 MPa
Qhov chaw nres nkoj helix kaum sab xis	22℃(ntev)	26 degree	24 degree
Governor caij nplooj ntoos hlav nqi	3.2 N / mm (hli)	2.8 N / hli	3.0 N / hli
Max xa tawm @ 1,800 rpm	410 mm³ / lub zog	310 mm³ (ntawm 1,800, tab sis siab dua ntawm 1,400)	380 mm3 ib

Qhov siab dua lub valve qhib siab (30 MPa) kom ntseeg tau tias cov kab txhaj tshuaj siab nthwv dej nce mus txog lub taub ntim lub taub hau sai dua ntawm qhov nrawm nrawm, thaum lub caij nplooj ntoos hlav stiffer tus tswv xeev txo qis qis - muab ze li kab rov tav ceev -load nkhaus (droop<3% when adjusted). The shallow spill helix produces a slower fuel cut-off, which smooths the torque delivery and reduces cyclic combustion noise.

Kev ntsuam xyuas lub rooj zaum ntawm qhov ntsuas EPS 200 sawv ntsug (roj ntawm 40 degree, ISO 4113) qhia 0R-2236 lub ntsiab lus: atoj siabKev xa tawm ntawm 1,400 thiab 2,000 rpm, qhov ntim nyob hauv ± 2% ntawm 400 mm³ / stroke. Qhov no ua tiav los ntawm kev sib cuam tshuam ntawm qhov chaw khib nyiab thiab lub sijhawm nchuav - qhov chaw nres nkoj spill pib tsuas yog thaum lub khib tshaj 12 hli, txhais tau hais tias rau qhov kev thauj khoom ib txwm (rack 8-11 mm), qhov ua tau zoo ntawm cov hlab ntsha tseem yuav luag tas li.

Lub 0R-2236 yog lub Hoobkas pom zoo lub twj tso kua mis rau:

Standby thiab prime gen-sets(Caterpillar 3412-powered, 50/60 Hz) qhov kev ruaj ntseg zaus yog qhov tseem ceeb.

Cov chaw nres tsheb roj compressiontsav tsheb reciprocating compressors nrog tas li torque xav tau.

Marine auxiliary generatorsthiabbow thruster power packsuas ua haujlwm nyob ze -kho rpm rau ncua sij hawm.

Nws yogtsis yogpom zoo rau qhov sib txawv -kev nrawm nrawm (piv txwv li, marine main engines) lossis tawm - tsheb thauj khoom loj- cov ntawv thov tau txais txiaj ntsig los ntawm 201-4202's torque- nce profile. 0R-2236's ca nkhaus yuav ua rau qeeb qeeb hauv kev hloov pauv hauv cov xwm txheej ntawd. Ib txwm hla kev siv lub cav serial tooj thiab daim ntawv thov code kom paub meej tias tsim nyog; peb pab neeg tuaj yeem txheeb xyuas siv Cat SIS database.

Peb 0R-2236 remanufactured twj tau dhau los ua cov txheej txheem tshwj xeeb kom tswj tau qhov muag muag-chaw nres nkoj helix geometry:

Tshuaj strippingntawm cov pa roj carbon deposits uas tsis yog -abrasive da dej uas tsis hloov lub helix ntug.

Cua - ntsuasntawm lub plunger- chim tshem tawm mus rau 0.003-0.004 hli (Qib A) - ib qho hnav tshaj 0.008 hli ua rau muaj kev hloov tag nrho ntawm ob qho tib si.

Kev xa khoom valve lappingnrog pob zeb diamond muab tshuaj txhuam kom ua tiav qhov tseeb 30 MPa qhib siab; peb xyuas qhov no nrog lub siab -kev daws teeb meem siab transducer.

Tswv xeev dynamic calibration- peb simulate tag nrho cov load-rejection test uas siv lub tshuab hluav taws xob dynamometer, sau cov droop thiab isochronous stability. Txhua chav tsev los nrog 5-point calibration daim ntawv pov thawj qhia tias xa khoom tiag tiag ntawm 1,200, 1,500, 1,800, 2,000, thiab 2,200 rpm, nrog kev sib txawv ntawm cov npe teev tseg.

Tag nrho cov ntsaws ruaj ruaj tau hloov kho rau Viton® FKM kom tiv taus cov khoom siv biodiesel (txog B20) thiab kub kub. Tom qab ntawd lub twj tso kua mis yog khiav - nyob rau hauv rau 45 feeb ntawm 1,800 rpm los daws cov springs ua ntej kev soj ntsuam zaum kawg.

Q1: Lub 0R-2236 puas tuaj yeem siv rau ntawm 3412 lub cav thaum pib nrog 10R-1001 yam tsis muaj kev hloov kho?
Lub cev muaj, tab sis cov roj xa tawm calibration txawv -the 0R-2236 yuav xa cov roj tsawg me ntsis ntawm cov khib nyiab, uas tuaj yeem txo lub zog siab tshaj plaws los ntawm ~ 5%. Tej zaum koj yuav tsum tau kho lub tag nrho-load nres ntsia hlau kom them, tab sis peb xav kom sab laj lub cav qhov kev ua tau zoo spec kom paub meej tias daim ntawv thov lub zog yuav tsum tau ua.

Q2: Yuav ua li cas yog qhov siab dua lub valve qhib siab cuam tshuam rau kev ua haujlwm injector?
Lub 30 MPa qhib siab ua rau lub siab nce siab nyob rau hauv cov kab txhaj tshuaj, nce qhov tseeb pib txhaj tshuaj los ntawm kwv yees li 0.2 ms ntawm 1,500 rpm piv rau 10R-1001. Qhov no yuav txhim kho combustion efficiency tab sis yuav ua rau kom cov neeg kho tshuab suab nrov; peb xav kom kuaj xyuas lub injector nozzle qhib siab-lawv yuav tsum sib phim.

Q3: Dab tsi yog qhov pom zoo roj pom qib rau lub twj tso kua mis no kom ua tiav qhov kev pabcuam siab tshaj plaws?
Peb pom zoo kom cov lim thawj ntawm 10 µm thiab theem nrab ntawm 5 µm (tsis meej). Lub plunger- chim clearance yog nruj; cov khoom loj dua 5 µm tuaj yeem tau qhab nia ntawm qhov chaw, txo qhov kev ua haujlwm ntawm volumetric. Siv cov roj / dej cais tawm sab saud thiab.

Q4: Nws puas tuaj yeem hloov pauv 0R-2236 los ntawm isochronous mus rau kev ua haujlwm poob?
Tau-tus tswv vaj tsev nyob muaj ib qho kev hloov kho sab nraud. Tig nws clockwise nce droop (txog 8%). Txawm li cas los xij, peb qhia kom ua qhov no tsuas yog nyob rau ntawm lub rooj sib tw sim kom paub tseeb tias qhov ua tau nrawm -load yam ntxwv, vim tias kev hloov kho teb feem ntau tsis meej.

Q5: Puas yog lub twj tso kua mis tuaj nrog lub iav tsav tshiab, lossis peb puas rov siv lub qub?
Lub twj tso kua mis yog muab rau yam tsis muaj lub iav tsav -koj yuav tsum hloov cov iav uas twb muaj lawm los ntawm koj lub twj qub qub, kom ntseeg tau tias tus yuam sij thiab lub qhov rooj tuav tau zoo. Peb pom zoo kom hloov cov ntsia hlau tuav nrog ib qho tshiab (Cat part 8M-3689) thiab torquing rau 120 N·m nrog Loctite 242.

Q6: Kuv tuaj yeem txheeb xyuas tau li cas tias lub twj tso kua mis remanufactured tsis tau hloov kho kom txo tau roj kev lag luam?
Peb daim ntawv pov thawj calibration teev cov khoom xa tuaj ntawm tsib speeds. Koj tuaj yeem hla - txheeb xyuas cov txiaj ntsig no tawm tsam OEM specification (muaj nyob rau hauv peb lub tsev qiv ntawv technical). Tsis tas li ntawd, peb muab lub calibration ntsia hlau nrog ib tug tamper - pom tseeb xim; Yog tias tawg, lub warranty yog voided.

 

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!
