Roj Txhaj Pump Plunger 00U2026/U2026 - Flow Linearity Thiab Governor-Response Harmonization Rau High-Speed ​​Weifu Inline Pumps

Nyob rau hauv lub cav diesel, tus neeg kho tshuab lossis hluav taws xob tus tswv xeev tso siab rau qhov kev sib raug zoo ntawm qhov chaw khib nyiab thiab cov roj xa tuaj kom muaj kev ruaj ntseg ceev raws li qhov sib txawv. Thaum lub plunger txoj kev xa khoom nthuav qhia tsis yog-linearity- qhov twg cov khib nyiab me me tsim cov roj hloov pauv loj ntawm qee txoj haujlwm- tus tswv xeev yuav tsum tsis tu ncua dhau-kho, ua rau kev yos hav zoov nrawm, tsis zoo teb, thiab siv roj ntau ntxiv. Lub 00U2026/U2026 Roj Txhaum Pump Plunger, tsim los ntawm Weifu, yog engineered nrog lub hom phiaj ntawm kev khiav linearity- qhov sib xws ntawm cov roj xa tawm nkhaus hla tag nrho cov khib nyiab mus ncig. Tsis zoo li cov plungers uas yooj yim qhov tsis tu ncua-lub kaum sab xis helixes uas tsim cov khoom tsis sib xws, 00U2026/U2026 nta ib qho kev nce qib-pitch helix (18.5℃thaum pib, tapering mus rau 20.5℃ntawm tag nrho stroke) uas tsim ib txoj kab ncaj nraim ntawm txoj hauj lwm khib thiab xa roj ntim. Qhov linearity no ua kom ntseeg tau tias tus tswv xeev ua haujlwm nyob rau hauv nws qhov kev tswj hwm qhov zoo, tswj xyuas kev ceev ceev ntawm ± 0.5% nyob rau hauv cov xwm txheej tsis tu ncua -a 60% kev txhim kho dua li cov pa plungers uas feem ntau pom ± 1.2% kev cai yuam kev. Rau cov neeg ua haujlwm genset, qhov no txhais tau tias nruj dua tswj (49.8-50.2 Hz), thaum rau cov neeg tsav tsheb, nws txhais tau tias ua kom muaj zog dua, muaj peev xwm ua kom muaj zog ntau dua uas txo cov neeg tsav tsheb qaug zog thaum lub sij hawm ntev.

Lub plunger 00U2026 / U2026 muaj lub npe ntawm txoj kab uas hla ntawm 8.5 hli nrog stroke ntawm 7.8 hli, xa lub ntim ntim ntawm 442 mm³. Qhov kev nce qib-pitch helix yog hauv av mus rau qhov tseeb ntawm ± 0.1 degree, nrog lub ntse txiav-tawm ntug vojvoog ntawm 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 3.0-3.4 µm ntawm 20 degree. Internal to tsawg dua los yog sib npaug li 0.9 cm³ / min ntawm 100 bar ntsuas siab. Static flow ntawm tag nrho cov khib nyiab thiab 1,200 rpm yog calibrated rau 390-415 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 48-52 Nm) thiab lub teeb ci, nrog tag nrho qhov siab ntawm 41.5 hli.

Lub 00U2026/U2026 yog tsim los rau inline twj (A-type thiab P-hom configurations) pab 4- thiab 6-lub tog raj kheej cav nrog kev hloov ntawm 4.0 mus rau 8.0 litres. Nws yog tshwj xeeb tshaj yog haum rau cov ntawv thov uas yuav tsum tau ceev ceev tswj- xws li gensets (50/60 Hz), marine auxiliary engines, thiab irrigation pumps-qhov twg tus tswv xeev cov lus teb yog qhov tseem ceeb. Nws kuj tseem tsim nyog rau cov tsheb thauj khoom ntawm txoj kev loj uas muaj kev nrawm nrawm thiab kev tswj xyuas kev caij nkoj zoo ib yam. Weifu muab cov plunger no rau OEMs suav nrog Yuchai, Weichai, thiab FAW, thiab nws muaj los ntawm kev lag luam tom qab hauv Asia, Latin America, thiab Africa.

00U2026/U2026's progressive-pitch helix yog tsim los tiv thaiv lub ntuj non-linearity tshwm sim los ntawm qhov chaw nres nkoj geometry. Ntawm qhov chaw qis qis, lub kaum sab xis ntawm lub kaum sab xis (18.5 degree) ua rau cov roj nruab nrab nce ib kauj ruam ntawm cov khib nyiab, thaum nyob rau ntawm cov khib nyiab ntau dua, lub kaum sab xis (20.5 degree) ua kom cov roj xa tsis tau "khiav" raws li cov khib nyiab mus txog tag nrho cov load -ib qho tshwm sim uas ua rau overspeeds nyob rau hauv lub generators. Qhov kev nce qib no ua rau muaj qhov yuam kev tsis sib xws ntawm tsawg dua 1.5% hla 75% ntawm cov khib nyiab mus ncig, piv rau 4.0% rau cov qauv helixes.

Kev kuaj pom zoo rau 00U2026/U2026 yog tus tswv xeev-lus teb lag (GRL) kev sim, uas ntsuas lub sij hawm coj mus rau lub cav ceev kom ruaj khov tom qab 10% load kauj ruam hloov. Lub plunger noj qab nyob zoo qhia tau hais tias GRL tsawg dua 1.2 vib nas this rau lub genset. Yog tias GRL tshaj 2.0 vib nas this, lub plunger qhov ntws tawm tau degraded, feem ntau yog vim kev tswj hwm ntug.

❓ Qhov kev nce qib-pitch helix piv rau tus qauv helix li cas?
Tus txheej txheem helix muaj lub kaum sab xis, ua ib qho kev xa tawm tsis-linear. Qhov kev nce qib-pitch helix hauv 00U2026/U2026 tsim cov kab hluav taws xob xa hluav taws xob, ua rau tus tswv xeev cov lus teb ruaj khov thiab kwv yees.

❓ 00U2026/U2026 puas tuaj yeem siv rau hauv lub tshuab hluav taws xob uas twb muaj tus tswv xeev hluav taws xob?
Yog lawm, tab sis tus tswv xeev hluav taws xob yuav xav tau nws cov PID tsis tau rov ua dua kom tau txais txiaj ntsig zoo los ntawm kev txhim kho linearity. Ib tug linear plunger txo qhov kev xav tau rau kev txhoj puab heev derivative nce nqis.

❓ Ntev npaum li cas yuav tsum xeem tus tswv xeev- teb lag luam?
Rau gensets, sim txhua 2,000 teev ua haujlwm. Yog tias GRL nce siab tshaj 1.5 vib nas this, tshawb xyuas lub plunger thiab tus tswv xeev mechanism. Yog tias lub plunger hnav, hloov nws.

❓ Puas yog lub plunger no sib haum nrog biodiesel blends?
Yog lawm, nitrocarburised nto muab corrosion kuj. Txawm li cas los xij, biodiesel lub viscosity siab dua yuav cuam tshuam me ntsis rau cov yam ntxwv ntws; kev kuaj xyuas linearity tom qab kev teeb tsa raug pom zoo.

❓ Dab tsi yog qhov kev pab cuam lub neej nyob rau hauv daim ntawv thov genset?
Hauv kev tsim hluav taws xob tas mus li, 00U2026 / U2026 feem ntau kav 8,000-10,000 teev. Kev saib xyuas GRL yog qhov qhia tau zoo tshaj plaws ntawm lub neej tseem tshuav.

❓ Kuv yuav khaws ib qho khoom seem 00U2026/U2026 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. Yog tias qhib, npog nrog cov roj diesel huv thiab muab khi rau hauv lub hnab yas.
