Ukuthwala yinxalenye ebalulekileyo yokuxhasa ukusebenza okuqhelekileyo kwemoto, ukongeza kulawulo lwenkqubo yokuvelisa, uyilo kunye noqwalaselo lwethwala yemoto kubaluleke kakhulu, okufanaimoto ethe nkqo kunye nemoto ethe tyekufuneka ukhethe uqwalaselo lweebheri ezahlukeneyo, iimfuno zesantya ezahlukeneyo zemoto kufuneka zikhethe neebheri ezahlukeneyo.
1 uqwalaselo lweIibheringi zeemoto ezithe tye
Ibhereyitha yebhola kunye nebhereyitha yekholamu kufuneka zisetyenziswe kangangoko kunokwenzeka kuzo zombini iziphelo zeinjini ethe tyeOkwangoku, injini yasekhaya enezibonda ezimbini ezincinci neziphakathi isebenzisa iibheringi zebhola ezingaphezu kwezibini, nangona abanye abavelisi benze uhlengahlengiso oluthile kwindawo yokunyamezelana kobubanzi bangaphakathi bebheringi kwicala lendawo evulekileyo, ukuze kuncitshiswe ingxaki yokuba ibhola icinezelwe emva kokuba ibheringi ifudunyeziwe. Nangona kunjalo, ngenxa yokuba i-expansion coefficient ye-bearing jacket inkulu kuneyeendawo zentsimbi ephothiweyo eziphethe igumbi lokuthwala - isigqubuthelo sokugqibela okanye isingxobo se-bearing, kwaye ubushushu kwi-bearing jacket buphezulu, i-bearing jacket inokutyibilika kancinci kwigumbi lokuthwala kubushushu begumbi, kodwa ibheringi isenokungakwazi ukuhamba emva kokuba ifudunyeziwe ngexesha lokusebenza. Esi sesona sizathu siphambili sokuba ubomi be-bearing bufutshane kwaye kulula ukubufudumeza xa kusetyenziswa iibheringi zebhola ezimbini. Emva kovavanyo lokunyuka kobushushu bemoto ngeebheriya ezimbini zebhola, imota iyamiswa ukulinganisa ukunyuka kobushushu, kwaye ngamanye amaxesha ibheriya yemoto iyatsha okwesibini, isizathu kukuba ukuvuleka kwebheriya yebhola akunakuthwala ukwanda kobushushu kunye nokuxinana okubandayo kwerotor, kwaye ijakethi ayinakungena kwigumbi lokuthwala, ukuze ibhola ikwazi ukuthwala amandla amakhulu e-axial abangelwa yi.
Ukuba kukhethwe i-ball bearing enye kunye ne-column bearing enye, ezi ngxaki zingasentla zinokuphetshwa. Ngomzi-mveliso wemoto ongcono kwinombolo yesakhelo se-H560 kwiImoto ene-voltage ephezulu enezibonda ezimbini, ukususela ekusetyenzisweni kokuqala kwee-ball bearing ezimbini ukuya kwi-ball bearing, i-column bearing, isiphumo sokusebenza emva kwexesha silungile kakhulu. Ukongeza ekutshintshweni kwee-bearing ngokwexesha eliqhelekileyo lokugcinwa, akukho mpazamo ngexesha lokusebenza okuqhelekileyo. Kwaye ubushushu obulinganiswa kwi-bearing buyi-20℃ kuphela. Eli lityala lokuqala eliphumeleleyo lokutshintsha ii-ball bearing ezimbini zemveli zibe yi-ball bearing enye kunye ne-column bearing enye yee-motors ezineepali ezimbini eTshayina, kwaye iye yakhuthazwa kancinci kancinci kwii-motors ezingakwaziyo ukuqhuma.
Ukuze kusonjululwe ingxaki yobushushu nengxolo emva kokuba isantya esilinganiselweyo seebheriyali zebhola sithatyathelwe indawo ziibheriyali zekholamu, iibheriyali zekholamu zoluhlu lokukhanya zingasetyenziswa, kwaye zibekwe kwisiphelo sangaphandle sefeni, imeko yokupholisa ilungile, kwaye ingxolo yeebheriya ingafakwa nayingxolo yefeni. Ukuba amandla emoto enezibonda ezimbini makhulu, uhlobo lweebheriyali likhulu, kwaye uthotho lokukhanya lweebheriyali zekholamu kunzima ukuhlangabezana neemfuno zesantya esilinganiselweyo, igrisi yeebheriyali ingatshintshwa ibe yioyile encinci.
2 Uqwalaselo lweebheringi zeemoto ezithe nkqo
Xa i-motor ethe nkqo isetyenziselwa ukutsala i-barrel pump kwinkqubo ye-petrochemical, ngenxa yamandla e-axial axial akhawulezileyo e-multistage barle pump ekuqaleni, kunye neemfuno zothutho, kwaye ukuze kupheliswe umonakalo obangelwe kukwanda kobushushu be-rotor ukuya kwi-bearing, i-vertical barrel pump motor (zombini iipali ezi-2 okanye iipali ezi-4), i-upper bearing ye-motor kufuneka kukhethwe ii-single-row single-stripetal thrust ball bearings. Ii-column bearings zee-low bearings kufuneka zisakhethwe njengoluhlu olukhanyayo. Ukuze kuthintelwe umonakalo kwii-thrust ball bearings, i-twoIibheringi kufuneka zibe namandla e-axial asele efakiwe kwijakethi yokuthwala. Ubukhulu bamandla kukuqinisekisa ukuba ibheringi ayonakaliswa ngamandla e-axial angasemva ukusuka kwisiphelo solwandiso lwe-shaft ukuya kwisiphelo esingengumthwalo ngexesha lokuthuthwa nokuqaliswa.
