Roj Pump Rotor PM Sintered Part
Cov roj twj tso kua mis ntau, qhov loj ntawm nws cov roj tso zis nce nrog qhov nce ntawm lub cav ceev, thiab kev sib raug zoo ntawm ob yog linear. Txhawm rau kom ntseeg tau tias cov roj tso tawm tsawg kawg nkaus ntawm qhov qis qis thiab cov roj tsawg kawg nkaus ntawm kev kub ceev, cov roj twj tso kua mis yuav raug tsim kom loj dua, uas tso siab rau cov kev xav tau ntau dua rau kev teeb tsa ntawm lub cav compartment.

Koj paub ntau npaum li cas txog cov hmoov hlau metallurgy hauv cov twj siv roj? Tam sim no, cov twj tso kua roj cav thiab cov twj tsis siv neeg kis tau tus mob feem ntau siv cov roj twj tso kua mis, uas feem ntau yog cov twj tso kua mis sab nraud, cov twj siv hluav taws xob sab hauv lossis cov twj tso kua mis sab hauv. yog ua los ntawm.
Cov roj twj tso kua mis ntau, qhov loj ntawm nws cov roj tso zis nce nrog qhov nce ntawm lub cav ceev, thiab kev sib raug zoo ntawm ob yog linear. Txhawm rau kom ntseeg tau tias cov roj tso tawm tsawg kawg nkaus ntawm qhov qis qis thiab cov roj tsawg kawg nkaus ntawm kev kub ceev, cov roj twj tso kua mis yuav raug tsim kom loj dua, uas tso siab rau cov kev xav tau ntau dua rau kev teeb tsa ntawm lub cav compartment. Nyob rau tib lub sijhawm, thaum lub cav khiav ntawm kev kub ceev, cov roj lubricating ntau dhau yuav rov qab los ntawm cov roj hluav taws xob, uas ua rau lub cav siv hluav taws xob ntau ntxiv. Lub twj tso kua mis hloov pauv roj yuav kho cov roj siab thiab cov roj ntim raws li kev ua haujlwm ntawm lub cav, kom ua tiav lub hom phiaj ntawm kev txuag roj.
Research data show that in an engine using a fixed displacement oil pump, when the speed is >2500r / min, kwv yees li 50 feem pua ntawm cov roj cav nrog lub hwj chim yuav ntws ncaj qha rov qab mus rau cov roj twj tso kua mis inlet kab noj hniav los yog roj lauj kaub los ntawm lub siab nyem valve, nqa lub zog Kev siv cov roj twj tso kua mis hloov pauv cov roj twj tso kua mis feem ntau tuaj yeem txuag roj los ntawm 2 feem pua rau 5 feem pua, thiab txo CO2 emissions los ntawm 1 feem pua rau 2 feem pua.
Cov twj hloov pauv hloov pauv feem ntau muaj cov qauv xws li cov twj tso kua mis sab nraud, cov twj tso kua mis vane, thiab cov twj tso kua mis zawv zawg. Cov twj tso kua mis sab nraud, xws li Volkswagen's EA888 qhov project, ib qho ntawm cov iav muaj qhov ruaj khov axial txoj hauj lwm, thiab lwm yam iav yog kho nrog lub siab los ntawm lub caij nplooj ntoos hlav. Thaum idling, ob lub iav yog tag nrho meshed. Thaum qhov ceev nce, lub siab ntawm cov roj twj tso kua mis kuj nce. Raws li nws nce, lub meshing ib feem ntawm lub iav yuav luv dua tom qab lub caij nplooj ntoos hlav yog compressed, thiaj li hais tias cov dej ntws ntawm lub twj tso kua mis tuaj yeem hloov kho txhua lub sijhawm. Lub zog ntawm hom twj tso kua mis no yog tsim los ntawm hmoov metallurgy.
Lub twj tso kua mis sib txawv ntawm vane (saib daim duab 4) feem ntau yog tsim los ntawm stator, rotor thiab vanes, thiab ob qho tib si stator thiab rotor yog hmoov metallurgy qhov chaw. Lub hauv paus ntsiab lus ua haujlwm ntawm vane hloov pauv hloov pauv twj tso kua mis yog los kho cov eccentricity los ntawm lub siab los kho qhov ntws. Lub hauv paus ntsiab lus ntawm zawv zawg vane hloov pauv twj tso kua mis yog qhov tseem ceeb tib yam li lub twj tso kua mis vane sib txawv, thiab qhov ntws tau raug kho los ntawm kev kho cov eccentricity. Ntawm lawv, zawv zawg vane yog ib qho hlau, lub tes tsho nruab nrab yog txuas nrog zawv zawg vane, lub tes tsho zawv zawg yog sab nraud, thiab lub rotor yog nyob rau hauv nruab nrab. Peb qhov no yog tag nrho cov hmoov metallurgy qhov chaw.
