Iyini iBearing Yokushisa Okuphansi

Ibhereyi enokushisa okuphansi ayibhekiseli kubhereyiyi esebenza ngokuqina ezindaweni ezinokushisa okuphezulu (ngokungafaniamabheringi okushisa okuphezulu), kodwa kunalokho ibhereyi eklanywe ngezinto ezikhethekile kanye nemiklamo yesakhiwo ukunciphisa i-coefficient yokungqubuzana, ngaleyo ndlela kuncishiswe ukushisa okungqubuzanayo. Lokhu kuvumela ibhereyi ukuthi igcine izinga lokushisa eliphansi ngisho nangesikhathi sokusebenza isikhathi eside.

 

AmabheringiAma-bearings anezinga lokushisa lokusebenza elingaphansi kuka-60℃ abhekwa njengama-bearings anezinga lokushisa eliphansi. Asetshenziswa kakhulu kuma-liquid pump ahlukahlukene, njenge-liquid gas pumps, ama-liquid nitrogen (hydrogen, oxygen) pumps, ama-butane pumps, ama-liquid pumps ama-rocket nama-missile, ama-spacecraft, njalo njalo.

 

Izinga Lokushisa Elisebenzayo Lama-Bearings Aphansi Okushisa

Izinga lokushisa lokusebenza lebhereyi elinokushisa okuphansi libonisa ubuchwepheshe bezinto ezibonakalayo kanye nezinga lokukhiqiza lebhereyi. Lilinganiswa ngokuyinhloko ngomehluko wokushisa phakathi kwendandatho yangaphandle yebhereyi kanye namafutha okupholisa ajoviwe ngesikhathi sokusebenza. Izinga lokushisa eliphansi lokusebenza lisho isikhathi eside sokuthwala kanye nokusebenza okuphezulu.

 

Izigaba zama-Bearings Asezingeni Eliphansi Lokushisa

Ama-bearings anezinga lokushisa eliphansi ngokuvamile ama-single-row deep groove ball bearings kanye nama-cylindrical roller bearings.

 

NgobaamabheringiUma ibhekene nokuquleka emazingeni okushisa aphansi, isici sangaphandle ukushintsha kwezinga lokushisa, kuyilapho isici sangaphakathi siyizinhlanganisela ezahlukene zokwandisa ukushisa zeshaft, uhlaka, nezinto zokwakha. Uma izinga lokushisa likhulu, izinto zokwakha ezahlukene ziyancipha ngamazinga ahlukene, kunciphisa ukuvuleka futhi kubangele ukuminyana. Ngakho-ke, ngemishini enobubanzi bokusebenza, kufaka phakathi imishini esetshenziswa emazingeni okushisa aphansi, kubalulekile ukubala izinhlanganisela zokwandisa zezinto zokwakha, futhi lapho kungenzeka khona, sebenzisa izinto ezinezinhlanganisela ezifanayo zokukhulisa ukuze uthole imiphumela engcono.

 

Ngaphezu kwalokho, ekwakhiweni kwesakhiwo, kuyalulekwa ukugwema ukusebenzisa i-roller bearing eyindilinga ekugcineni ngakunye kwe-shaft. Esimweni esinjalo, uma ibanga elide phakathi kwama-bearing amabili, kulapho amathuba okuthi aqhume khona aphezulu. Uma kufakwa ama-bearing amabili anciphile ekugcineni kwe-shaft, angasebenza njengendawo yokubeka i-shaft, evimbela ukunyakaza kwe-axial. Esinye isiphelo se-shaft, esisetshenziswa ne-rolling bearing, sivimbela kuphela amandla e-radial, okuvumela ukunyakaza kwe-axial okulinganiselwe kanye nokushintsha kwezinga lokushisa kwe-axial.

 

Ukukhethwa Kwezinto Zokusebenzisa Ama-Bearings Asezingeni Eliphansi Lokushisa

Ukukhethwa Kwensimbi Yokuthwala Ama-Bearings Asezingeni Eliphansi Lokushisa

Ama-bearings anezinga lokushisa eliphansi avame ukwenziwa ngezinsimbi zensimbi ezingenasici ezingama-9Cr18 noma ezingama-9Cr18Mo, futhi angenziwa ngethusi le-beryllium, izinto zobumba, nezinye izinto. Ngaphansi kwamazinga okushisa aphansi kakhulu okusebenza (izinga lokushisa eliphakeme kakhulu -253℃), uma umkhawulo wokusebenza udinga -253℃, izinto ezingama-6Cr14Mo zingakhethwa kodwa kumele zisetshenziswe endaweni engenamanzi.

 

Ngesikhathi sokusebenzisa ama-bearings anokushisa okuphansi, kufanele kuqashelwe izinkinga ezifana nokushisa ngokweqile okubangelwa ukugcotshwa okungekuhle, ngakho-ke kubalulekile ukukhetha ukugcotshwa okufanelekile.
