Roj Txhaum Pump Plunger 00U3002 / U3002 - Lub Sijhawm Precision Retention Nrog Tsawg-Drift Calibration Rau Kev Txuas Ntxiv-Lub Luag Haujlwm Diesel Cav

Nyob rau hauv ib tug diesel roj txhaj system, thawj calibration raug ntawm ib tug tshiab plunger tsuas yog qhov pib taw tes; qhov kev ntsuas qhov tseeb ntawm qhov zoo yog qhov zoo npaum li cas uas qhov tseeb tau khaws cia ntau tshaj kaum tawm txhiab lub sijhawm ua haujlwm. Txhua lub twj tso kua mis diesel muaj kev hloov pauv hloov pauv hauv cov roj xa tawm raws li lub plunger thiab chim hnav- qhov tshwm sim hu ua calibration drift- uas ua rau tus tswv xeev nce rack txoj hauj lwm los them rov qab, txo tus tswv xeev txoj kev kho cov npoo thiab thaum kawg ua rau cov lus teb qeeb qeeb. Lub 00U3002/U3002 Roj Txhaj Pump Plunger, tsim los ntawm Weifu, yog engineered tshwj xeeb los txo qhov drift los ntawm kev sib xyaw ua ke ntawm cov khoom siv tshwj xeeb uas tsis tshua muaj hnav thiab cov txheej txheem kho cua sov uas ua rau muaj kev ruaj khov, nplua-grain microstructure. Tsis zoo li cov pa plungers uas feem ntau qhia txog 3-4% drift hauv kev xa roj tom qab 5,000 teev ua haujlwm, 00U3002 / U3002 yog tsim los tswj nws cov khoom xa tuaj hauv ± 1.2% ntawm qhov qub calibration nyob rau tib lub sijhawm - qib kev ua tau zoo tshwj xeeb tshaj yog rau cov cav uas ua haujlwm rau lub sijhawm tsis tu ncua, propulsion units, thiab irrigation twj tso kua mis. Rau cov neeg ua haujlwm, qhov no txhais tau tias tsis tshua muaj kev rov ua dua tshiab, tsawg dua kev hloov kho tsis tau teem sijhawm, thiab kev ua tau zoo ntawm lub cav ntau dua thoob plaws lub twj tso kua mis lub neej ua haujlwm.

Lub plunger 00U3002 / U3002 muaj lub npe ntawm txoj kab uas hla ntawm 9.0 hli nrog stroke ntawm 8.5 hli, xa lub ntim ntim ntawm 541 mm³. Kev tswj helix yog hauv av mus rau lub kaum ntse ntse ntawm 21℃± 0.15 degree, nrog rau kev txiav tawm ntug ntawm qhov tsawg dua lossis sib npaug li 0.018 hli. Lub plunger nto tiav rau Ra 0.04 µm, nrog lub thoob lapped rau Ra 0.03 µm, ua tiav qhov sib tw ntawm 3.2-3.6 µm ntawm 20 degree. Internal to tsawg dua los yog sib npaug li 1.0 cm³ / min ntawm 100 bar ntsuas siab. Static flow ntawm tag nrho cov khib nyiab thiab 1,200 rpm yog calibrated rau 460-485 mm³ ib stroke, nrog ib tug unit-rau-unit variation ntawm tsawg dua los yog sib npaug rau ± 1.5%. Cov khoom siv plunger yog high-chromium steel (sib npaug rau 1.2358) nrog cov tub ntxhais hardness ntawm 58-62 HRC, thiab cov nitrocarburised nto rau 1,000 HV. Lub rooj sib txoos suav nrog cov txiv ntoo tuav (torque 52-56 Nm) thiab lub teeb ci, nrog tag nrho qhov siab ntawm 42.5 hli.

Lub 00U3002 / U3002 yog tsim los rau inline twj (MW thiab P-hom configurations) pab 6- thiab 8-lub tog raj kheej xyaw nrog kev hloov ntawm 8.0 mus rau 15.0 litres. Nws yog tshwj xeeb tshaj yog haum rau cov ntawv thov uas lub cav ua haujlwm ntawm cov khoom ruaj khov rau lub sijhawm ntev - xws li gensets (50/60 Hz), marine propulsion, thiab irrigation twj. Nws lub sij hawm ntev precision retention txo qhov yuav tsum tau recalibration. Weifu muab cov plunger no rau OEMs suav nrog Weichai, Yuchai, thiab FAW, thiab nws muaj los ntawm kev lag luam tom qab hauv South America, Africa, thiab Southeast Asia.

Lub 00U3002 / U3002 qhov txo qis yog ua tiav los ntawm cov khoom siv ua kom zoo nrog cov qauv zoo-grain martensitic thiab cov txheej txheem tshwj xeeb tempering uas tsim kom muaj qhov ruaj khov, hnav-resistant nto. Qhov no ua kom ntseeg tau tias qhov kev tshem tawm tau nce ntawm tus nqi qeeb dua -tsuas yog 0.02 µm rau 1,000 teev- tuav tswj qhov tseeb kom ntev dua.

00U3002/U3002's calibration stability tuaj yeem soj ntsuam los ntawm kev taug qab cov roj xa tuaj ntawm tag nrho cov khib nyiab thaum lub sij hawm niaj hnub ntsuas. Ib qho kev noj qab haus huv plunger qhia tau hais tias muaj tsawg dua 0.5% ntawm 1,000 teev. Yog hais tias lub drift tshaj 1.0% rau 1,000 teev, lub plunger tus nqi tau nrawm dua.

❓ Yuav ua li cas lub low-drift tsim cuam tshuam rau lub twj tso kua mis recalibration intervals?
Cov twj tso kua mis haum nrog 00U3002/U3002 feem ntau yuav tsum tau rov ua dua 30-40% tsawg dua li cov qauv plungers- ncua sijhawm ntawm 4,000 mus rau 6,000 teev rau kev ua haujlwm txuas ntxiv.

❓ Dab tsi yog cov cim qhia ntawm ntau dhau calibration drift?
Cov cim qhia suav nrog kev poob qis ntawm lub zog tag nrho, tus tswv xeev mus txog qhov siab tshaj plaws ntawm qhov chaw khib nyiab, thiab nce qhov cua kub. Txoj kev tsom xam ntawm cov roj xa khoom yuav paub meej tias drift.

❓ 00U3002/U3002 puas tuaj yeem siv rau hauv lub cav uas ua haujlwm ntawm cov khoom sib txawv?
Yog, lub plunger yog haum rau tag nrho cov load profiles. Txawm li cas los xij, nws cov qauv qis-drift yog qhov zoo tshaj plaws hauv kev siv nrog lub sijhawm ua haujlwm ntev, ruaj khov.

❓ Puas yog lub plunger no sib haum nrog biodiesel blends?
Yog lawm, nitrocarburised nto tiv thaiv biodiesel acidity. Txawm li cas los xij, saib xyuas drift ntau zaus nrog biodiesel, vim tias nws cov roj qis tuaj yeem ua rau hnav.

❓ Ntev npaum li cas yuav tsum ntsuas qhov sib txawv?
Rau gensets thiab marine applications, ntsuas txhua 2,000 teev. Yog tias drift tshaj 1.0% rau 1,000 teev, npaj rau kev hloov.

❓ Kuv yuav khaws cov khoom seem 00U3002 / U3002 li cas?
Khaws rau hauv qhov chaw qhuav, tswj qhov kub thiab txias (15-25 degree) nrog cov av noo qis dua 60%, hauv nws cov khoom qub los tiv thaiv zoo li qub.
