Roj Txhaum Pump Plunger 00U325 / U325 - Nto-Energy Optimization Thiab Ciaj-Daim Duab Tsim Kom Txhim Kho Scuffing Resistance

Nyob rau hauv ib puag ncig kev kub siab ntawm lub twj tso kua roj diesel, cov zaj duab xis lubricating nruab nrab ntawm lub plunger thiab chim feem ntau raug txo kom tsawg dua 1 µm-ib txoj cai uas hydrodynamic lubrication lov thiab ciam lubrication yuav siv sij hawm dhau. Hauv kev tswj hwm no, kev ua haujlwm tiv thaiv scuffing yog txiav txim siab tsis yog los ntawm cov khoom ntawm cov roj, tab sis los ntawm lub peev xwm ntawm qhov chaw los txhawb kev tsim cov yeeb yaj kiab tiv thaiv ciam teb los ntawm cov tshuaj adsorption. Lub 00U325/U325 Roj Txhaj Pump Plunger, tsim los ntawm Weifu, yog engineered nrog ib tug nto-zog profile uas nquag txhawb lub adsorption ntawm polar molecules los ntawm cov roj-xws li fatty acid esters thiab lwm yam trace lubrication additives -kom tiv thaiv direct-hlau zaj duab xis. Tsis zoo li cov pa plungers uas qhov saum npoo tsuas yog hardened, lub plunger no muaj qhov zoo ntawm nitrocarburised nto nrog ib qho kev sib npaug ntawm lub zog ntawm lub zog- tau ua tiav los ntawm kev tswj cov txheej txheem txheej txheem thiab kev kho oxidative zaum kawg - uas ua kom zoo dua qhov adsorption ntawm ciam lubricants. Hauv kev ntsuam xyuas scuffing, 00U325 / U325 tiv thaiv lub nra ntawm 2,800 N ua ntej tsis ua haujlwm, piv rau 2,100 N rau cov qauv plungers, sawv cev rau 33% kev txhim kho hauv kev ua haujlwm scuffing-ib qho txiaj ntsig tseem ceeb rau cov tshuab ua haujlwm nrog cov roj tsawg-sulphur diesel roj uas tau txo lub cev lub cev.

Lub plunger 00U325 / U325 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 nta ib txheej txheej nitrocarburised nrog ib tug compound-zone composition optimized rau ciam-film tsim (ε‑Fe₂‑₃N theem nrog tswj porosity). Qhov saum npoo yog 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 ± 1.6%. Cov khoom siv plunger yog high-chromium steel (sib npaug rau 1.2358) nrog cov tub ntxhais hardness ntawm 58-62 HRC. 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 00U325 / U325 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 tsis tshua muaj sulfur diesel los yog biodiesel blends yog siv - roj uas tau txo lub ntuj lubricity thiab paub tias yuav ua rau muaj kev pheej hmoo ntawm scuffing. Lub plunger no kuj raug pom zoo rau cov tshuab ua haujlwm hauv cheeb tsam uas cov roj zoo sib txawv, vim nws qhov kev txhim kho ciam teb-zaj duab xis tsim muaj kev tiv thaiv ntxiv. 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 00U325/U325 tus tailored nto muaj pes tsawg leeg tsim ib tug nto zog uas yog pom zoo rau adsorption ntawm polar lubricity molecules. Qhov no ua kom ntseeg tau tias txawm tias thaum lub bulk lubricating zaj duab xis yog tsawg, cov ntaub ntawv tiv thaiv molecular los tiv thaiv scuffing.

00U325/U325's ciam teb-zaj duab xis kev ua tau zoo tuaj yeem raug soj ntsuam los ntawm kev sim scuffing-load, qhov twg lub plunger raug nce mus txog thaum scuffing tshwm sim. Lub plunger noj qab nyob zoo qhia tau hais tias scuffing load ntau dua los yog sib npaug rau 2,600 N. Yog hais tias lub scuffing load poob qis dua 2,200 N, qhov nto tau poob nws ciam teb-zaj duab xis txhawb zog.

Cov txheej txheej saum npoo-zog-optimized tseem ua tau zoo nyob thoob plaws qhov kev ua haujlwm kub, nrog rau qhov sib txawv ntawm qhov sib txawv ntawm qhov tsawg dua 8% ntawm -20℃rau +120 degree.

❓ Qhov kev ua kom zoo tshaj plaws ntawm lub zog sib txawv li cas ntawm qhov tawv tawv?
Hardness resists abrasive hnav, thaum lub zog nto-zog optimization txhawb kev tsim cov tshuaj tiv thaiv zaj duab xis uas tiv thaiv scuffing - ib qho kev tsis ua hauj lwm sib txawv.

❓ Dab tsi yog cov tsos mob ntawm kev ua yeeb yaj kiab txo qis?
Cov tsos mob muaj xws li maj mam nce hauv kev sib txhuam quab yuam, kev ua haujlwm siab dua, thiab cov tsos ntawm cov qhab nia zoo. Kev kuaj scuffing-load yuav paub meej tias qhov xwm txheej.

❓ 00U325/U325 puas siv tau nrog cov roj sulfur siab?
Yog lawm, tab sis kev tiv thaiv scuffing tsis yog qhov tseem ceeb nrog cov roj sulfur siab, uas muaj lubricity zoo dua qub. Lub plunger tseem yuav ua haujlwm zoo.

❓ Puas yog lub plunger no sib haum nrog biodiesel blends?
Yog lawm, kev kho saum npoo tiv thaiv biodiesel acidity thiab txhawb kev tsim ciam teb nrog biodiesel cov polar molecules.

❓ Ntev npaum li cas yuav tsum tau ua qhov kev xeem scuffing-load?
Rau cov cav uas siv cov roj uas muaj roj tsawg, ua txhua 2,000 teev. Yog tias scuffing load poob qis dua 2,200 N, tshuaj xyuas lub plunger nto.

❓ Kuv yuav khaws cov khoom seem 00U325 / U325 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. Tsis txhob kov qhov chaw kom khaws nws cov khoom siv tshuaj.
