110 Series Injector Extractor - Torsional-Assisted Withdrawal For Carbon-Locked Units

Lub 110 series injector-ib txwm muaj nyob rau hauv Weichai WP10/WP12, FAW 6DL, thiab Sino-truck MC07 cav-tsim ibcarbon-induced adhesive daim ntawv cog lusntawm lub rooj zaum nozzle tom qab ncua kev pabcuam. Daim ntawv cog lus tsis yog kev sib txhuam nkaus xwb; nws tshwm sim los ntawm aCov tshuaj tiv thaiv thermo-chemicalqhov twg high-temperature combustion gases nkag mus rau lub injector lub sealing interface, polymerising mus rau hauv ib tug nyuaj, glassy deposit uas ua zoo li ib tug cement. Tej yam yooj yim axial rubers feem ntau ua tsis tau vim lawv sim kov yeej kev sib txhuam thiab adhesion ib txhij, qee zaum tshaj 5,000 N yam tsis muaj kev vam meej. Qhov no110 Series Injector Extractorqhia atorsional-pab tshem tawmmechanism uas siv cov tswj kev sib hloov oscillation (± 15 degree) thaum tswj cov axial nro, ua rau cov pa roj carbon monoxide shear lub zog ua ntej (uas feem ntau yog 30% qis dua nws lub zog tensile), ces rho tawm lub injector nrog tsawg zog - feem ntau nyob rau hauv 2,000 N.

Lub extractor qhov tseem ceeb innovation yog adual-action tsav lub taub hauuas converts tus neeg teb xov tooj phau ntawv rotation rau hauv:

Axial nro- los ntawm ib tug zoo-pitch ntsia hlau (Tr20 × 4, self-locking lub kaum sab xis 4 degree), thov mus txog 4,000 N ntawm rub quab yuam

Oscillatory torsion- los ntawm lub ntiaj teb iav uas sib npaug ntawm tus kov kev sib hloov mus rau ± 15℃reciprocating motion ntawm ib zaus ntawm 2 oscillations ib tug puv tes tig

Qhov no torsional oscillation yog tshwj xeeb tuned rau lub ntuj zaus ntawm cov pa roj carbon deposits shear modulus (kwv yees li 1.2 Hz), tsim ib tugcov nyhuv resonanceuas nce zuj zus lawm cov nplaum daim ntawv cog lus tsis shocking lub injector lub cev. Tus neeg teb xov tooj tuav tswj kev sib hloov tsis tu ncua, thiab lub tshuab rho tawm tau hloov pauv ntawm rub thiab sib tw, txo cov kev tawm dag zog uas xav tau los ntawm qhov nruab nrab ntawm 55% piv rau cov ntshiab axial rubers.

Lub extractor cuam tshuam nrog lub injector ntawm aceev-hloov collet setuas tuav lub injector tus xaiv rho tawm feature-xws li lub dab tshos threaded (M22 × 1.5 los yog M24 × 1.5) los yog lub annular groove nyob rau hauv qab ntawm cov hluav taws xob connector. Cov khoom muaj xws li tsib collets:

Collet Xim	Ntaus hom	Txoj kab uas hla	Injector Variant
Liab	Xov	M22×1.5	110 Mechanical (P-tswj)
Xiav	Xov	M24×1.5	110 CRIN 2.4 (Wichai)
Ntsuab	Groove	Ø 18.0 hli	110 CRIN 2.2 (FAW)
Daj	Groove	Ø 19.5 hli	110 CRIN 3.0 TSI
Txiv kab ntxwv	Xov	M24 × 1.5 hli	110 nrog txuas ntxiv dab tshos

Txhua collet ntaInternal helical serrationsuas tso cai rau lub collet kom nws tus kheej nruj raws li axial nro nce - tib lub hauv paus ntsiab lus raws li ib tug collet chuck ntawm lub tshuab milling. Qhov no ua kom qhov tuav tau muaj zog dua nyob rau hauv kev thauj khoom, tiv thaiv txhua qhov slippage uas tuaj yeem ua rau lub tshuab nqus tsev puas tsuaj. Cov collets yog machined los ntawmhardened hlau 4140(48–50 HRC) nrog amanganese phosphate txheejtiv thaiv galling.

Lub extractor muaj xws li acoj lub tes tshouas swb hla lub cev txhaj tshuaj thiab sau npe tawm tsam lub tog raj kheej lub taub hau counterbore. Lub tes tsho ua peb txoj haujlwm:

Axial alignment- xyuas kom lub extractor lub rub axis yog coaxial nrog lub injector bore (± 0.3 degree)

Kev tiv thaiv kab mob- tiv thaiv lub extractor lub cev los ntawm kev tiv thaiv lub tog raj kheej taub hau sealing nto

Carbon-shield- ua raws li cov khib nyiab khib nyiab, muaj cov pa roj carbon monoxide uas tshem tawm thaum lub sijhawm rho tawm

Lub tes tsho yog tsim los ntawmiav puv PEEK- cov khoom uas nyuaj dua li cov pa roj carbon deposits tab sis softer dua li lub tog raj kheej lub taub hau cam khwb cia hlau, txhais tau tias nws yuav tsis tau lub taub hau txawm tias tilted. Lub tes tsho yog hloov tau thiab suav nrog qhov taw qhia hnav: cov xim xim uas ploj mus tom qab kwv yees li 200 lub voj voog rho tawm.

Kev npaj- Xaiv lub collet kom raug rau lub tshuab txhaj tshuaj variant; txuas lub tes tsho qhia rau lub tog raj kheej taub hau siv lub nplhaib nruab nrab.

Kev koom tes- Xaub lub extractor hla lub injector, koom nrog lub collet los ntawm tig lub dab tshos (tes-tight), thiab paub meej tias zoo xauv.

Oscillation-rub- Tig lub ntsiab kov nyob rau hauv ib tug khov kho clockwise zog (25–35 N·m). Lub extractor cia li siv oscillatory torsion; txuas ntxiv mus kom txog rau thaum lub injector tawg dawb - qhov no yog audibly qhia los ntawm kev hloov nyob rau hauv kov kuj.

Kev rho tawm- Tom qab lub injector tso tawm, hloov mus rau ncaj rub (tsis muaj oscillation) los ntawm nias lub khawm xaiv hom; ua kom tiav cov extraction nrog du kov rotation.

Kev tshem tawm- Disengage lub collet thiab thim lub extractor; tshuaj xyuas lub injector thiab lub bore rau ib qho seem ntawm cov pa roj carbon monoxide (siv daim iav tsom iav).

Tag nrho cov txheej txheem rho tawm feem ntau yuav siv sijhawm 3-5 feeb rau cov pa roj carbon-locked injector, piv rau 10-15 feeb nrog phau ntawv swb rauj.

Q1: Puas yog qhov torsional oscillation puas ua rau lub taub hau lub taub hau lossis lub tog raj kheej lub taub hau?
Tsis yog. Lub oscillation yog txwv rau ± 15℃thiab lub torque yog capped ntawm 8 N·m ntawm lub injector-zoo hauv qab 12 N·m yield txwv. Lub load yog siv rau lub cev lub cev lub dab tshos / zawj, tsis yog lub nozzle. Lub tog raj kheej taub hau tsuas yog axial nro los ntawm lub tes tsho qhia, tsis torsional load.

Q2: Kuv yuav ua li cas thiaj paub yog tias lub tshuab rho tawm raug ua kom raug ua ntej pib?
Cov lus qhia lub tes tsho lub pob tshab tso cai pom qhov pom tseeb tias lub tes tsho tau zaum tag nrho tawm tsam lub tog raj kheej taub hau counterbore. Tsis tas li ntawd, lub extractor kov muaj xws li ib tug me me ntsuj plig theem; Thaum lub npuas yog nruab nrab, lub axis nyob rau hauv ± 0.3℃ntawm ntsug- txaus rau kev nyab xeeb extraction.

Q3: Kuv puas tuaj yeem siv lub tshuab rho tawm ntawm cov tshuaj txhaj tshuaj uas tau welded los yog staked los tiv thaiv tamper ntsuas?
Tsis yog. Yog tias lub tshuab txhaj tshuaj tau raug welded lub cev los yog ua haujlwm tas mus li, tsis muaj lub tshuab rho tawm yuav tshem tawm yam tsis muaj kev puas tsuaj rau lub tog raj kheej taub hau. Peb lub cuab yeej yog rau lub Hoobkas-spec khaws cia nkaus xwb- tshuaj xyuas kom pom kev hloov kho ua ntej siv.

Q4: Dab tsi yog qhov txawv ntawm qhov extractor no thiab cov pa swb rauj?
Ib qho swb rauj siv lub zog loj cuam tshuam rau kev thauj khoom, uas tuaj yeem ua rau lub cev poob siab thiab ua rau lub tog raj kheej lub taub hau xov. Peb cov extractor siv du, tswj tensile thiab torsional loads, txo kev ntxhov siab concentration. Nws kuj tseem muab cov lus teb tsis txaus ntseeg- tus neeg teb xov tooj hnov ​​​​qhov kev sib cog lus, es tsis hnov ​​nws.

Q5: Kuv yuav tsum tau hloov lub collet hnav li cas ntau zaus?
Cov collets 'internal serrations raug ntsuas rau 500 rho tawm mus ua ntej tuav efficiency txo. Tom qab 400 cycles, peb pom zoo kom hloov lub collet. Lub cim qhia hnav yog laser-etched ntawm txhua lub collet; thaum lub cim ua flush nrog qhov chaw nyob ib puag ncig, nws yog lub sijhawm rau kev hloov pauv. Hloov collets muaj nyob rau ntawm tus kheej.

Q6: Lub tshuab rho tawm tsis ua txhaum lub tshuab txhaj tshuaj dawb txawm tias tom qab 5 feeb -dab tsi ntxiv?
Nres thiab siv tshuaj lom neeg los ntawm lub hollow siab ntsia hlau. Yog hais tias lub injector tseem tsis txav mus tom qab 10 feeb ntawm cov kuab tshuaj nyob, lub injector tej zaum yuav muaj ib tug neeg kho tshuab tuav feature (xws li, ib tug circlip los yog ib tug thib ob lock) uas tsis tau muab tshem tawm ua ntej extraction. Nrog rau lub cav qhov kev pab cuam phau ntawv rau disassembly cov kauj ruam ua ntej sim dua.
