Roj Txhaj Pump Plunger 00U274 / U274 - Load-Adaptive Response Thiab Mechanical-Governor Synchronization Rau Weifu Inline Pump Systems

Hauv cov tshuab tswj hwm lub tshuab hluav taws xob, lub twj tso kua mis plunger tsis yog tsuas yog hloov pauv roj- nws ua haujlwm raws li kev txuas ntxiv hydraulic ntawm tus tswv xeev qhov kev hnov ​​​​mob, txhais cov lus txib rau cov khoom siv rau hauv cov roj xa nrog ib qho kev lag luam tshwj xeeb uas txhais lub cav qhov kev lees paub ntawm lub cav. Lub 00U274/U274 Roj Txhaj Pump Plunger, tsim los ntawm Weifu, yog engineered nrog ib tug load-adaptive teb profile uas synchronises nrog lub inherent lub sij hawm tsis tu ncua ntawm mechanical Governors. Qhov no yog ua tiav los ntawm kev ntsuas kev sib cuam tshuam ntawm lub plunger lub helix geometry thiab nws cov yam ntxwv kev sib txhuam, tsim kom muaj kev tswj xyuas qeeb hauv kev xa cov roj uas phim tus tswv xeev tus cwj pwm tsis tu ncua. Tsis zoo li cov plungers nrog cov lus teb nrawm dhau uas ua rau tus tswv xeev overshoot thiab tom qab nrawm nrawm nrawm, lossis cov lus teb qeeb dhau uas ua rau kev nrawm nrawm, 00U274 / U274 muab cov roj nrawm nrawm nrawm uas tso cai rau tus tswv xeev kom ruaj khov nrawm yam tsis muaj oscillation. Hauv kev sim cav, qhov kev sib txuas ua ke no txo ​​qis qhov nrawm nrawm thaum lub sij hawm 50% load kauj ruam los ntawm 8% mus rau 5.5%, thiab lub sij hawm daws teeb meem los ntawm 3.2 vib nas this mus rau 2.1 vib nas this- kev txhim kho uas txhais ua kev tsav tsheb zoo dua hauv cov tsheb thiab nruj dua kev tswj hwm hauv gensets.

Lub plunger 00U274 / U274 muaj ib 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 rau lub thoob lapped rau Ra 0.03 µm, ua tiav qhov sib tw clearance 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, 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 00U274/U274 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 qhov tshwj xeeb tshaj yog haum rau cov tshuab tswj hwm lub cav uas tus tswv xeev-plunger synchronization yog qhov tseem ceeb- xws li gensets (50/60 Hz), marine propulsion, thiab off-highway machinery. Nws kuj yog ib qho kev xaiv nrov rau cov tsheb loj loj uas cov lus teb du, ruaj khov yog nyiam tshaj li kev nrawm nrawm. 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.

00U274/U274 cov lus teb yog kho los ntawm helix geometry thiab kev sib txhuam saum npoo los muab cov roj xa tawm ntawm 0.8 ms- txuam nrog tus tswv xeev ntsuas kev lag luam. Qhov no ua kom tus tswv xeev thiab lub plunger ua haujlwm sib raug zoo.

Lub 00U274/U274 tus tswv xeev-plunger synchronization tuaj yeem ntsuas los ntawm kev ntsuas lub sijhawm thauj khoom (LST)- lub sijhawm ua rau lub cav ceev kom ruaj khov tom qab 50% load kauj ruam. Lub plunger noj qab nyob zoo qhia tau tias LST tsawg dua 2.5 vib nas this. Yog tias LST tshaj 3.5 vib nas this, lub plunger cov lus teb tau ua qeeb dhau.

❓ 00U274/U274 txawv ntawm 00U217/U217 li cas?
00U274/U274 muaj cov lus teb qeeb qeeb (0.8 ms lag) kom phim cov tswv xeev, thaum lub 00U217/U217 yog tsim los kom ceev ceev-tsim nyob rau hauv hluav taws xob tswj systems.

❓ Dab tsi yog cov tsos mob ntawm lub plunger uas teb nrawm dhau rau nws tus tswv xeev?
Lub cav yuav yos hav zoov rau kev ceev, oscillating nyob ib ncig ntawm lub setpoint, thiab tej zaum yuav overshoot thaum load txais. Tus tswv xeev yuav hloov kho tas li, ua rau tsis sib xws.

❓ Cov plunger no puas tuaj yeem siv rau hauv lub cav nrog tus tswv xeev hluav taws xob?
Yog lawm, tab sis tus tswv xeev cov kev txwv tej zaum yuav tsum tau rov ua kom rov qab los ntawm tus lej plunger cov lus teb tus yam ntxwv.

❓ Puas yog 00U274 / U274 tau tshaj 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 lus teb; saib xyuas LST.

❓ Yuav tsum ntsuas lub sijhawm thauj khoom ntau npaum li cas?
Rau gensets, ntsuas txhua 2,000 teev. Rau marine lossis off-highway, txhua 1,500 teev.

❓ Kuv yuav khaws cov khoom seem 00U274 / U274 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.
