L'Orange Common Rail Pump Test Adapter Kit - Flange, Coupling, High-Pressure & Inlet Fittings Rau Lub Rooj Zaum Validation

Lub L'Orange common rail twj tso kua mis (siv nyob rau hauv MTU Series 4000, 2000, thiab tej yam MAN / Scania high-speed engines) yog ib tug precision-engineered tivthaiv uas yuav tsum tau validated ntawm lub rooj ntev zaum xeem tom qab overhaul. Txawm li cas los xij, lub twj tso kua mis qhov tshwj xeeb interface geometry- tsis yog tus qauv mounting flange, splined tsav coupling nrog rau cov backlash tshwj xeeb kam rau ua, thiab muaj tswv yim siab-siab thiab inlet chaw nres nkoj threads - ua rau kev sib txuas ncaj nraim tsis tuaj yeem tsis muaj cov khoom siv tshwj xeeb. Cov khoom siv kuaj dav dav feem ntau xau ntawm kev kub siab (Ntau dua lossis sib npaug ntawm 1,800 bar), qhia txog kev sib raug zoo uas cuam tshuam rau lub twj tso kua mis phasing, lossis tsis ua kom rov ua dua lub twj tso kua mis hauv lub tsheb roj. Qhov noL'Orange Common Rail Pump Test Adapter Kitmuab tag nrho interface teeb, suav nrog covmounting flange, tsav coupling, high-pressure qhov hluav taws xob haum, thiabinlet roj connector, engineered tshwj xeeb rau L'Orange twj. Cov khoom siv hloov pauv txhua tus qauv Bosch-type test bench rau hauv L'Orange-compatible validation station, with to leak-tight seals, correct phasing, and agent flow features.

Txhua yam khoom yog precision-manufactured rau L'Orange OEM interface specifications, xyuas kom meej tias lub twj tso kua mis yog mounted, tsav, thiab plumbed raws nraim li nws yuav nyob rau hauv lub engine - tshem tawm cov kev ntsuas yuam kev uas tshwm sim los ntawm kev siv generic adapters.

Lub mounting flange yog lub hauv paus ntawm kev teeb tsa. Nws yog ibib daim hlau forging(42CrMo4, quenched thiab tempered rau 38 HRC), nrog apiloted nrhiav txoj kab uas hlantawm 125.0 hli (h6 kam rau ua, −0.025/−0.050 mm) uas sib koom nrog lub twj tso kua mis mounting register. Lub flange tus ntsia liaj qhov rooj qauv (4 × M10, 100 mm PCD) phim lub L'Orange twj tso kua mis tus qauv mounting qhov. Atus pin(Ø 8.0 hli, ntawm qhov chaw ruaj khov angular) muab kev sib hloov ua kom zoo, kom ntseeg tau tias lub twj tso kua mis lub sij hawm cov qhab nia sib haum nrog lub rooj ntev zaum siv thaum ntsia.

Lub flange yog av ntawm ob lub ntsej muag mus rau qhov tiaj tus ntawm 0.01 hli thiab qhov kawg ntawm Ra 0.8 µm. Apilot bore(Ø 30.0 hli, H7) lees txais cov tsav txuas txuas lub ncej, nruab nrab ntawm qhov txuas mus rau lub rooj zaum tsav. Lub flange yog ruaj rau lub rooj ntev zaum lub taub hau tsav nrog plaub M10 × 30 qhov (socket-head cap screws), thiab lub twj tso kua mis tau ruaj khov rau lub flange nrog plaub M10 × 40 screws (tseem suav nrog). Lub flange lub ntsej muag sab nrauv suav nrog alaser-engraved alignment markuas sib haum mus rau lub twj tso kua mis saum-dead-centre (TDC) txoj hauj lwm, tso cai rau tus kws kho mob mus rau theem lub twj tso kua mis yam tsis siv lub sij hawm sib cais.

Kev sib txuas ntawm lub drive yog alub tes tsho-type couplingnrog rau sab hauv spline uas koom nrog lub twj tso kua mis tsav ncej (26-hniav, 30℃siab lub kaum sab xis, raws li ISO 4156). Lub coupling yog tsim los ntawmCase-carburising steel 18CrNiMo7-6, hardened rau 58-60 HRC ntawm lub spline flanks, nrog ib tug tseem ceeb toughness ntawm 35 HRC. Spline yoghauv av rau chav kawm haum ntawm 6H / 6g, muab qhov backlash ntawm 0.08–0.12 mm- sib piv cov thawj cav lub iav tsheb ciav hlau clearance. Qhov kev thim rov qab no yog qhov tseem ceeb vim tias qhov kev tshem tawm ntau dhau tso cai rau kev sib hloov txoj kab nqes, hloov lub twj tso kua mis phasing; clearance tsis txaus ua rau kev khi thiab overheating ntawm high speeds.

Lub coupling feature axauv-nut(M20 × 1.5) uas ruaj nws rau lub rooj ntev zaum tsav ncej, nrog alub tshuab ntxhua khaub ncaws(Belleville hom) uas tswj preload nyob rau hauv thermal expansion. Lub coupling sab nrauv muaj xws li aknurled dab tshosrau tes-tightening thaum pib installation, thiab aset-ntsia hlau(M6 × 1.0) uas ntsuas qhov sib txuas mus rau lub rooj zaum ncej thaum phasing tau lees paub. Lub coupling yog sib npaug rau ISO 1940-1 qib G6.3 ntawm 3,000 RPM, kom ntseeg tau tias kev ua haujlwm tsis muaj kev vibration ntawm kev ntsuas ceev.

Lub qhov hluav taws xob siab siab txuas txuas L'Orange lub twj tso kua mis qhov hluav taws xob qhov hluav taws xob (M18 × 1.5, 60℃lub khob hliav qab lub rooj) mus rau lub rooj ntev zaum qhov ntsuas siab (tus qauv M14 × 1.5 lossis M16 × 1.5, nyob ntawm lub rooj ntev zaum). Lub fitting yog aob-thooj sib dhos: ib threadedadapteruas screws rau hauv lub twj tso kua mis lub qhov hluav taws xob, thiab iblub tes tsho adapteruas txuas mus rau lub rooj ntev zaum lub high-pressure hose.

Adapter- 17-4PH stainless hlau, H900 mob (44 HRC), nrog aconical sealing ntsej muagav rau 60℃thiab lapped rau Ra 0.08 µm. Lub khob hliav qab yog sib phim rau lub twj tso kua mis lub qhov hluav taws xob lub rooj, tsim kom muaj hlau-rau-hlau foob uas tiv taus 2,500 bar yam tsis muaj cov ntsaws ruaj ruaj ntxiv lossis ntxhua khaub ncaws.

Lub tes tsho- 316L stainless hlau, nrog cov xov sab hauv kom phim lub rooj zaum hose (M14 × 1.5 lossis M16 × 1.5, teev ntawm kev txiav txim). Lub tes tsho muaj xws li atig nutuas tso cai rau lub hose mus rau oriented yam tsis muaj twisting.

Qhov haum lub internal bore yog4.0mm ib-ua rau L'Orange twj tso kua mis lub qhov hluav taws xob bore- kom tsis txhob muaj kev txwv tsis pub khiav. Tag nrho cov ntim tuag (qhov ntim roj ntim nruab nrab ntawm lub twj tso kua mis thiab lub rooj ntev zaum kab) yog tsawg dua 0.5 cm³, txo qis lub sijhawm nce siab yuam kev thaum lub sijhawm ntsuas dynamic.

Q1: Puas yog cov khoom siv no puas ua haujlwm nrog txhua lub twj tso kua mis L'Orange, lossis puas muaj cov kev hloov pauv uas yuav tsum tau hloov kho ntxiv?
Cov khoom siv npog ntau dua 95% ntawm L'Orange twj siv hauv MTU 4000 series cav, suav nrog P-pump, CRI 2.4, 3.0, thiab marine 3.2 variants. Rau MAN/Scania variants nrog ib tug txawv mounting flange (xws li, 6-bolt qauv), peb muab ib tug xaiv adapter phaj-thov qhia koj lub twj tso kua mis qauv thaum xaj.

Q2: Lub qhov hluav taws xob muaj hluav taws xob haum muaj M18 × 1.5 xov- yuav ua li cas yog tias kuv lub rooj zaum sim siv cov xov sib txawv (xws li M16 × 1.5)?
Cov khoom siv suav nrog ib qholub tes tsho interchangeableuas hloov M18 xov rau M14 × 1.5 lossis M16 × 1.5. Lub tes tsho yog muab thiab tuaj yeem hloov pauv hauv qab 30 vib nas this. Yog tias koj lub rooj zaum siv cov xov sib txawv (xws li, 9/16-18 UNF), peb muab lub tes tsho kev cai - tiv tauj peb nrog koj lub rooj zaum cov ntsiab lus haum.

Q3: Kuv yuav ua li cas kom ntseeg tau tias qhov sib txuas ntawm cov tsav tsheb tau raug cuam tshuam nrog lub twj tso kua mis lub sijhawm?
Lub coupling yog non-indexed -nws tuaj yeem ntsia tau rau hauv txhua txoj haujlwm tig. Lub sij hawm yog teem los ntawm lub twj tso kua mis tus kheej lub sij hawm cim txheeb ze rau lub flange lub TDC qhia. Txhim kho lub twj tso kua mis rau ntawm lub flange siv qhov kev sib tw dowel, tom qab ntawd tig lub rooj zaum lub rooj zaum kom txog thaum lub twj tso kua mis TDC cim nrog lub flange lub cim. Xauv lub coupling's set-screw ntawm txoj hauj lwm ntawd-coupling's spline engagement tsis cuam tshuam rau lub sij hawm.

Q4: Kuv puas tuaj yeem siv lub tshuab hluav taws xob siab nrog biodiesel lossis roj sulfur siab?
Yog lawm. Lub 17-4PH stainless hlau thiab lub khob hliav qab foob yog sib xws nrog biodiesel mus txog B100 thiab nrog roj mus txog 1,000 ppm sulfur. Lub O-ring nyob rau hauv lub inlet connector yog FKM, uas tiv thaiv biodiesel o. Rau B100 daim ntawv thov, peb xav kom hloov O-ring ntau zaus (txhua 150 kev sib txuas tsis yog 200).

Q5: Lub mounting flange tus ntsia liaj qhov rooj qauv (100 mm PCD) zoo li tus qauv-Kuv puas tuaj yeem siv rau lwm hom twj tso kua mis (xws li Bosch CP3)?
Lub flange tus tsav txoj kab uas hla (125.0 mm) thiab dowel pin txoj hauj lwm yog tshwj xeeb rau L'Orange twj. Bosch CP3 twj siv ib txoj kab uas hla sib txawv thiab 4 × M12, 112 mm PCD qauv - lawv tsis sib xws. Peb muab cov khoom siv flange cais rau Bosch thiab Denso twj; thov xaj cov khoom siv tshwj xeeb rau koj lub twj tso kua mis.

Q6: Dab tsi yog torque specification rau inlet connector M16 × 1.5 xov?
Qhov pom zoo torque yog 25-30 N·m. Tsis txhob nruj heev- lub twj tso kua mis qhov chaw nres nkoj yog ib qho nyias-walled seem ntawm lub tsev thiab tuaj yeem cuam tshuam yog tias over-torqued. Qhov haum muaj xws li ib txoj kab torque txwv (ib qho cim ntawm qhov haum ntawm hex uas sib haum nrog lub twj tso kua mis qhov chaw nres nkoj ntawm 25 N·m) raws li kev qhia pom.
