Iphampu Yenjini Yokujova Kadizili Esezingeni Eliphezulu BH4PN120R Izingxenye Zenjini ye-WEICHAI TD226B-4

Njengengxenye ebalulekile yokungqubuzana kwephampu yegiya likaphethiloli, izici zokuthwala zinomthelela obalulekile ekusebenzeni okusebenzayo, ukwethembeka kanye nempilo yephampu kaphethiloli. Iphampu yesibaseli edlulisa i-medium kuphethiloli we-viscosity ephansi, emthwalweni omkhulu kanye nezimo zejubane eliphezulu, ubukhulu befilimu kawoyela obuncane be-bearing eshelelayo buncane kakhulu, ngokuyisisekelo bufana nobukhulu obufanayo nobulukhuni bezingxenye, ukugqokwa nokuklebhuka kalula. futhi ngaleyo ndlela kuholele ekuhlulekeni kokuslayida kwephampu yamafutha. Ku-lubricating medium viscosity kanye nokulayisha isimo esithile, isilinganiso se-sliding bearing clearance ratio (ibhekisela ekuqondisweni kwe-sliding bear kanye ne-shaft diameter clearance kanye ne-shaft diameter ratio) iyisici esiyinhloko sobukhulu befilimu obuncane, obuthinta ukuthwala. umthamo.

Ngakho-ke, ukuze kuxazululwe inkinga ukuthi ama-sliding bearings of fuel gear pumps athambekele ekugqokeni ngenxa yobukhulu befilimu yamafutha amancane, okuholela ekwehlulekeni kwama-sliding bearings ngaphansi komthwalo ophezulu kanye nezimo zejubane eliphezulu, futhi ngokubheka iqiniso lokuthi isilinganiso sokuvunyelwa yisici esiyinhloko esithonya ubuncane befilimu kawoyela ukushuba kwama-sliding bearings, ama-sliding bearings ohlobo oluthile lwamaphampu kaphethiloli athathwa njengento yocwaningo okufanele ifundwe futhi. ihlaziywa yi-PumpLinx simulation ukuze kutholwe ubuncane befilimu kawoyela ukushuba kwama-bearings, umthamo wokuthwala umthwalo, ingcindezi kanye nokusatshalaliswa kwezinga lokushisa kwama-bearings anezilinganiso ezihlukene zokuvunyelwa. Ubuncane befilimu kawoyela ukushuba, umthamo womthwalo, ingcindezi kanye nokusatshalaliswa kwezinga lokushisa kwama-bearings anezilinganiso ezihlukene zokuvunyelwa zihlaziywa nge-PumpLinx simulation. I-Flexural deformation ye-gear shaft yephampu kaphethiloli ethile iyahlaziywa, bese kuhlaziywa ubudlelwano phakathi kwenani le-sliding bear clearance ratio kanye nobukhulu obuncane befilimu kawoyela, umthamo womthwalo, izinga lokushisa elithwalayo kanye nokusatshalaliswa kwengcindezi ejikelezayo kanye ne-radial kuhlaziywa ngaphansi kwezimo ezimbili zokusebenza. , okungukuthi, isivinini esincane kanye nesivinini esiphezulu sepompo, ngokulandelanayo. Imiphumela ibonisa ukuthi: ngesilinganiso esifanayo sokuvunyelwa kwemvume, umthamo wokuslayida uyakhula lapho ukushuba kwefilimu kawoyela kuncipha; lapho isilinganiso sokuvunyelwa sincipha, amandla okuthwala ayanda; lapho ijubane landa, amandla okuthwala ayanda; ngokuphathelene kokubili ukusatshalaliswa kwengcindezi kanye nokukhuphuka kwezinga lokushisa, isimo esihle kakhulu sitholakala lapho isilinganiso sokuvuma esifanelekile se-gear shaft kanye ne-sliding bear yincane kakhulu.
