Roj Txhaj Pump Plunger 00U306 / U306 - Tswj Radial Clearance Thiab Volumetric-Efficiency Optimization Rau Weifu Inline Pump Systems

Hauv cov twj tso kua roj diesel, qhov radial clearance nruab nrab ntawm lub plunger thiab chim tsis yog los ntawm cov khoom ntawm kev tsim precision- nws yog ib qho kev txiav txim siab uas tswj lub twj tso kua mis volumetric efficiency, uas yog qhov piv ntawm cov roj tiag tiag xa mus rau qhov theoretical swept volume. Lub 00U306 / U306 Roj Txhaj Pump Plunger, tsim los ntawm Weifu, yog engineered nrog ib tug optimized radial clearance profile uas sib npaug ob qhov kev xav tau: txo qis kom muaj kev ua haujlwm siab volumetric, thaum ua kom txaus lubricating zaj duab xis los tiv thaiv scuffing thiab qaug dab peg. Tsis zoo li cov pa plungers uas qhov kev tshem tawm tau raug kho raws li qhov ua siab ntev, 00U306 / U306 nta qhov kev tshem tawm uas yog qib meej raws li qhov ntev ntawm lub plunger - me ntsis nruj ntawm qhov kawg siab (3.0 µm) thiab maj mam nce mus rau 3.6 µm tom qab kawg. Qhov kev kawm tiav kev tshem tawm no txo ​​cov dej xau ntawm thaj chaw tseem ceeb-tsim tsis muaj kev cuam tshuam rau lubrication ntawm qhov tsawg-loaded rov qab seem. Hauv kev sim lub rooj ntev zaum, qhov kev tsim no tau txhim kho lub twj tso kua mis volumetric efficiency ntawm 91% mus rau 94.5% ntawm 1,200 rpm thiab 1,200 bar-ib qho nce uas txhais ua ntau dua roj xa mus rau cov injectors rau tib lub camshaft torque, zoo txhim kho lub zog tso zis tsis muaj roj ntau ntxiv.

Lub 00U306 / U306 plunger muaj ib txoj kab uas hla ntawm 9.0 hli nrog stroke ntawm 8.5 hli, xa lub ntim ntim ntawm 541 mm³. Cov radial clearance yog kawm tiav: 3.0 µm nyob rau hauv high-pressure cheeb tsam (sab sauv 30% ntawm plunger mus ncig teb chaws) thiab 3.6 µm nyob rau hauv lub rov qab cheeb tsam (qis dua 70%), nrog ib tug du mus rau ib tug 2 hli mid-section. 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. Internal to yog tsawg dua los yog sib npaug li 0.9 cm³ / min ntawm 100 bar test siab, qhia txog qhov nruj dua qhov kev tshem tawm 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 ± 1.6%. 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 00U306 / U306 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 kev siv uas lub twj tso kua mis efficiency cuam tshuam rau tag nrho lub cav kev ua tau zoo- xws li cov tsheb thauj khoom hnyav, cov cav loj hauv hiav txwv ceev, thiab cov khoom siv roj av uas yog qhov kev txhawj xeeb tseem ceeb ntawm kev ua haujlwm. Nws kawm tiav clearance tsim muab ib tug ntsuas efficiency kom zoo dua tsis compromising durability. 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 00U306 / U306 qhov kev kawm tiav kev tshem tawm txo cov dej ntws tawm ntawm qhov chaw siab siab uas qhov sib txawv ntawm qhov siab tshaj plaws, thaum qhov kev tshem tawm loj me ntsis ntawm thaj tsam rov qab los xyuas kom muaj cov yeeb yaj kiab txaus rau lubrication. Qhov kev tsim no txo ​​qis cov kab mob parasitic thiab txhim kho lub twj tso kua mis hydraulic efficiency.

Lub 00U306 / U306 qhov kev tshem tawm tuaj yeem raug soj ntsuam los ntawm kev ntsuas qhov dej ntws tawm, uas ntsuas qhov ntws tawm ntawm qhov sib txawv ntawm lub plunger txoj haujlwm. Ib qho kev noj qab haus huv plunger qhia txog qhov hloov pauv ntawm tsawg dua 15% raws li mob stroke. Yog tias qhov kev hloov pauv ntau dua 30%, qhov kev kawm tiav tiav tau raug cuam tshuam.

Cov ntaub ntawv CTE-matched kom ntseeg tau tias cov ntaub ntawv kawm tiav kev tshem tawm tseem nyob ruaj khov ntawm qhov kev ua haujlwm kub, nrog rau qhov kev hloov pauv hloov tau txwv tsawg dua lossis sib npaug li 0.5 µm ntawm -20℃rau +120℃.

❓ Yuav ua li cas kawm tiav clearance piv rau ib tug uniform clearance nyob rau hauv cov nqe lus ntawm efficiency?
Cov kawm tiav kev tshem tawm muab 3-4% kev txhim kho hauv kev ua haujlwm ntawm volumetric los ntawm kev txo cov dej xau ntawm thaj chaw muaj kev kub ntxhov thaum tswj xyuas kom txaus lubrication ntawm thaj chaw rov qab.

❓ Dab tsi yog cov cim ntawm kev hnav khaub ncaws kawm tiav?
Cov cim qhia suav nrog kev poob qis ntawm lub zog thiab kev siv roj ntau ntxiv, vim tias lub twj tso kua mis xa cov roj tsawg dua rau tib txoj haujlwm khib. Qhov kev ntsuam xyuas qhov xau-profiling yuav lees paub qhov xwm txheej.

❓ 00U306 / U306 puas tuaj yeem siv rau hauv lub cav nrog cov roj sulfur siab?
Yog lawm, nitrocarburised nto tiv taus corrosion. Txawm li cas los xij, saib xyuas cov dej xau ntau zaus, vim tias cov roj sulfur siab tuaj yeem cuam tshuam rau kev tshem tawm.

❓ Puas yog lub plunger no sib haum nrog biodiesel blends?
Yog lawm, kev kho saum npoo tiv thaiv biodiesel acidity. Txawm li cas los xij, biodiesel lub viscosity siab dua tuaj yeem cuam tshuam cov yam ntxwv ntawm cov dej ntws; ua qhov kev ntsuam xyuas leakage-profiling tom qab kev teeb tsa.

❓ Yuav ua li cas thiaj li yuav tsum tau ua qhov kev ntsuam xyuas qhov dej-profiling?
Rau kev ua haujlwm tsis tu ncua thiab kev siv dej hiav txwv, ua txhua 2,000 teev. Yog tias qhov sib txawv ntawm qhov sib txawv ntau dua 30%, xyuas lub plunger thiab chim.

❓ Kuv yuav khaws ib qho khoom seem 00U306 / U306 plunger 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. Tiv thaiv qhov chaw clearance los ntawm kev sib cuag.
