Roj Txhaj Pump Plunger 00U3006 / U3006 - Dynamic Sealing Behavior Thiab Leakage-Mode Differentiation For Weifu Inline Pump Systems

Hauv cov twj tso kua roj diesel, lub plunger sealing kev ua tau zoo tsis yog cov cuab yeej tas li - nws hloov pauv hloov pauv thaum lub sijhawm mob stroke, cuam tshuam los ntawm plunger tshaj tawm, siab gradient, thiab cov ntaub ntawv tshem tawm sai sai. Lub 00U3006/U3006 Roj Txhaj Pump Plunger, tsim los ntawm Weifu, yog engineered nrog lub hom phiaj ntawm dynamic sealing tus cwj pwm, uas txiav txim seb qhov leakage tshwm sim thaum lub sij hawm qhov tseeb compression thiab spill theem- dua li qhov zoo li qub to ntsuas thaum so. Tsis zoo li cov pa plungers qhov twg zoo li qub thiab dynamic to zoo li qub, 00U3006 / U3006 nta kev tswj qhov chaw zoo nkauj thiab lub ntsej muag meej meej uas txo cov dynamic leakage tivthaiv txog li 30% ntawm siab plunger speeds, thaum tswj kom txaus lubrication. Qhov no ua tiav los ntawm lub thoob ntim nrog lub micro-taper (0.6 µm tshaj qhov ntev stroke) uas ua rau "hydrodynamic wedge" cuam tshuam, tsim kom muaj kev sib khi lub zog uas nce nrog lub plunger tshaj tawm - nquag tawm tsam cov dej xau uas yuav txwv tsis pub nce ntawm kev kub ceev. Hauv kev sim lub rooj zaum, 00U3006 / U3006 tau ua kom pom kev tawm dag zog tsawg dua 1.2 cm³ / min ntawm 1,800 rpm, piv rau 1.8 cm³ / min rau cov khoom tsis sib xws hauv plungers, uas ua rau muaj roj ntau dua thiab txo cov roj cua kub ntawm lub cav ceev.

Lub plunger 00U3006 / U3006 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 chim bore nta ib tug micro-taper ntawm 0.6 µm tshaj lub stroke ntev, tsim cov hydrodynamic sealing nyhuv. Lub plunger nto tiav rau Ra 0.04 µm, nrog lub thoob lapped rau Ra 0.03 µm, ua tiav qhov sib tw clearance ntawm 3.4 µm ntawm 20 degree. Internal to, ntsuas dynamically ntawm 1,800 rpm, tsawg dua los yog sib npaug rau 1.2 cm³ / min. 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 00U3006 / U3006 yog tsim los rau inline twj (MW thiab P-hom configurations) pab 6- thiab 8-lub tog raj kheej cav nrog kev hloov ntawm 8.0 mus rau 15.0 litres. Nws yog qhov tshwj xeeb tshaj yog haum rau cov ntawv thov kev kub ceev uas qhov kev sib khi zoo yog qhov tseem ceeb- xws li cov gensets ceev (1,800 rpm), marine propulsion, thiab tsheb cav ua haujlwm ntawm txoj kev loj ceev. Nws hydrodynamic wedge tsim kom txo cov pa tawm ntawm kev kub ceev, txhim kho roj efficiency thiab txo cov roj cua sov. 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 00U3006/U3006's micro-tapered chim bore tsim ib tug converging clearance nyob rau hauv cov kev taw qhia ntawm plunger motion. Raws li lub plunger txav mus, cov roj hauv qhov kev tshem tawm raug yuam los ntawm qhov sib txawv ntawm qhov nqaim, tsim kom muaj lub siab uas tawm tsam cov dej ntws tawm - cov nyhuv hydrodynamic wedge. Cov nyhuv no nce nrog lub plunger ceev, muab lub foob rau tus kheej.

00U3006/U3006 tus cwj pwm sealing tuaj yeem soj ntsuam siv qhov sib piv ntawm qhov sib txawv-static to (DSLR)- qhov piv ntawm cov dej xau ntsuas ntawm 1,800 rpm rau cov dej xau ntsuas hauv cov xwm txheej zoo li qub. Lub plunger noj qab nyob zoo qhia tau tias DSLR tsawg dua 1.5. Yog tias DSLR tshaj 2.0, cov nyhuv hydrodynamic wedge tau ploj lawm.

❓ Yuav ua li cas hydrodynamic wedge nyhuv txawv ntawm ib tug yooj yim nruj clearance?
Lub kaw ntom nti txo cov pa tawm ntawm txhua qhov nrawm tab sis ua rau muaj kev sib txhuam. Cov nyhuv hydrodynamic wedge muab kev sib txhuam qis ntawm qhov nrawm nrawm thiab nce kev sib khi ntawm qhov nrawm nrawm - tus yam ntxwv zoo rau tus kheej.

❓ Dab tsi yog cov tsos mob ntawm kev poob qis?
Cov tsos mob muaj xws li nce roj cua kub ntawm kev kub ceev, txo lub zog puv puv, thiab cov roj rov qab kub uas nce siab tshaj 10℃siab dua qhov kub ntawm qhov nkag. Kev kuaj DSLR yuav lees paub qhov poob.

❓ 00U3006 / U3006 puas tuaj yeem siv rau hauv lub cav qis qis?
Yog, lub plunger haum rau txhua qhov nrawm. Txawm li cas los xij, cov nyhuv hydrodynamic wedge yog qhov muaj txiaj ntsig zoo ntawm kev kub ceev - lub plunger tseem yuav ua tau zoo txaus ntawm qhov nrawm.

❓ Puas yog lub plunger no sib haum nrog biodiesel blends?
Yog lawm, nitrocarburised nto tiv thaiv biodiesel acidity. Txawm li cas los xij, biodiesel lub viscosity siab dua tuaj yeem cuam tshuam cov npoo npoo; saib xyuas DSLR tom qab 1,000 teev.

❓ Ntev npaum li cas yuav tsum ntsuas qhov dynamic-static to leakage ratio?
Rau high-speed gensets thiab marine applications, ntsuas txhua 2,000 teev. Yog tias DSLR tshaj 2.0, tshawb xyuas lub thoob taper thiab plunger nto.

❓ Kuv yuav khaws ib qho khoom seem 00U3006 / U3006 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 lub thoob bore los ntawm kev sib cuag.
