Ngaba uyazi ukuba imozulu ebandayo yenza ntoni kwiibheringi zamavili? Kwaye Njani ukunciphisa le mpembelelo imbi?

Kwiimeko ezininzi zokuveliswa kwamashishini kunye nokusebenza kwezixhobo zoomatshini, iibheringi zizinto eziphambili, kwaye ukuzinza kokusebenza kwazo kuhambelana ngqo nokusebenza okuqhelekileyo kwenkqubo yonke. Nangona kunjalo, xa kubanda kubanda kuya kuvela uluhlu lweengxaki ezinzima kunye ezinzima, eziza kuba nefuthe elibi kakhulu ekusebenzeni okuqhelekileyo kokuthwala.

 

Ukuncipha kwezinto

Iibheringi zihlala zenziwe ngentsimbi (umz. intsimbi), enepropati yokwandiswa kwe-thermal kunye nokunciphisa. Amacandelo eukuzala, njengamandandatho angaphakathi nangaphandle, izinto eziqengqelekayo, ziya kuncipha Kwiindawo ezibandayo. Ukuthwala ubungakanani obuqhelekileyo, i-diameter yangaphakathi nangaphandle inokucutheka ngee-microns ezimbalwa xa ubushushu behla ukusuka kwi-20°C ukuya kwi -20°C. Oku kucutheka kunokubangela ukuba ukukhutshwa kwangaphakathi kwebheringi kube kuncinci. Ukuba ukucocwa kuncinci kakhulu, ukungqubuzana phakathi komzimba ojikelezayo kunye namakhonkco angaphakathi nangaphandle kuya kwanda ngexesha lokusebenza, okuya kuchaphazela ukuguquguquka okujikelezayo kokuthwala, ukwandisa ukuchasana, kunye ne-torque yokuqala yesixhobo.

Ukuqina Ukutshintsha

Imozulu ebandayo iya kwenza ukuba ubunzima bezinto ezithwalayo zitshintshe kwinqanaba elithile. Ngokuqhelekileyo, iintsimbi ziba brittle kumaqondo obushushu aphantsi, kwaye ukuqina kwazo kuphakama ngokwentelekiso. Kwimeko yokuthwala intsimbi, nangona ukuqina kwayo kulungile, kusancitshiswa kwiindawo ezibandayo kakhulu. Xa ukuthwala kuxhomekeke kwimithwalo eyothusayo, olu tshintsho kubulukhuni lunokubangela ukuba ukuthwala kube lula ukuqhekeka okanye ukwaphuka. Ngokomzekelo, kwiibheringi zezixhobo zemigodi yangaphandle, ukuba zixhomekeke kwimpembelelo ye-ore ewela kwimozulu ebanda, kunokwenzeka ukuba yonakaliswe ngaphezu kweqondo lokushisa eliqhelekileyo.

Ukutshintsha kokuSebenza kweGrisi

Igrisi yenye yezinto eziphambili zokuqinisekisa ukusebenza kakuhle kweebheringi. Kwimozulu ebandayo, i-viscosity yegrisi iya kwanda. Igrisi eqhelekileyo inokuba ngqindilili kwaye inciphe ulwelo. Oku kwenza kube nzima ukwenza ifilimu ye-oyile elungileyo phakathi komzimba oqengqelekayo kunye nemidyarho yokuthwala. Kwi-motor bearing, igrisi inokuzaliswa kakuhle kuzo zonke izikhewu ngaphakathi kwiqondo lokushisa eliqhelekileyo. Njengoko iqondo lobushushu liyancipha, igrisi iba incangathi, kwaye umzimba oqengqelekayo awukwazi ukuzisa igrisi ngokufanayo kuzo zonke iindawo zonxibelelwano ngexesha lokuqengqeleka, nto leyo eyandisa ukukhuhlana kunye nokunxiba, kwaye isantya sayo esijikelezayo sinokuguquguquka, oko konakalise umgangatho womphezulu kunye nokuchaneka komgangatho wamalungu omatshini. Kwiimeko ezimandundu, kunokukhokelela ekufudumezeni okanye nasekuthabatheni i-bearing.

Ubomi Benkonzo obufutshane

Ukudityaniswa kwezi zinto, ukukhuhlana okwandisiweyo, ukuqina kwempembelelo encitshisiweyo kunye nokuthotywa kakubi kweebheringi kwimozulu ebandayo kunokukhawulezisa ukunxiba. Ngaphantsi kweemeko eziqhelekileyo, iibheringi ziyakwazi ukuqhuba amawaka eeyure, kodwa kwiindawo ezibandayo, ngenxa yokwanda kokunxiba, zinokubaleka iiyure ezingamakhulu ambalwa ziya kusilela, njengokunxiba komzimba okuqengqelekayo, i-raceway pitting, njl., Enciphisa kakhulu ubomi benkonzo yeebheringi.

 

Xa sijamelene nale miphumo mibi yemozulu ebandayo kwiibheringi, sifanele sizithobe njani?

Khetha Igrisi ekunene kwaye ulawule iSixa

Kwimozulu ebandayo, igrisi enentsebenzo entle yobushushu obuphantsi kufuneka isetyenziswe. Olu hlobo lwegrisi lunokugcina ubumanzi obulungileyo kumaqondo obushushu aphantsi, njengeemveliso ezinezongezo ezikhethekileyo (umzekelo, iigrisi ezisekelwe kwi-polyurethane). Azikho i-viscous kakhulu kwaye zinokunciphisa ngokufanelekileyo ukungqubana kweebheringi ngexesha lokuqalisa kunye nokusebenza. Ngokuqhelekileyo, indawo yokugalela (elona qondo lobushushu lisezantsi apho umfuziselo we-oyile opholileyo unokuhamba phantsi kweemeko zovavanyo oluchaziweyo) igrisi ezinobushushu obuphantsi kakhulu, kwaye ezinye zinokuba ngaphantsi ukuya kuma-40°C okanye nangaphantsi, oko kuqinisekisa ukuthambisa okulungileyo kweebheringi nakwimozulu ebandayo.

Umlinganiselo ochanekileyo wokuzaliswa kwegrisi nawo ubalulekile ekuthwaleni umsebenzi kwimozulu ebandayo. Igrisi encinci kakhulu iya kubangela ukuthambisa okungonelanga, ngelixa ukuzaliswa ngokugqithisileyo kuya kubangela ukuba ukuthwala kuvelise ukuxhathisa okukhulu kakhulu ngexesha lokusebenza. Kwimozulu ebandayo, ukugcwalisa kufuneka kugwenywe ngenxa yokunyuka kwe-viscosity yegrisi. Ngokuqhelekileyo, kwiibheringi ezincinci kunye nobukhulu obuphakathi, inani lokuzaliswa kwegrisi li malunga ne-1/3 - 1/2 yendawo yangaphakathi yokuthwala. Oku kuqinisekisa ukuthambisa kunye nokunciphisa ukuxhathisa okubangelwa yigrisi egqithisileyo.

 

Buyisela Igrisi Rhoqo kwaye Womeleze iTywina
Nangona igrisi efanelekileyo isetyenziswe, kunye nokuhamba kwexesha kunye nokusebenza kokuthwala, igrisi iya kungcoliswa, i-oxidized kunye nokunye. Ezi ngxaki zinokuba mandundu kwimozulu ebandayo. Kucetyiswa ukuba unciphise umjikelo wokutshintshwa kwegrisi ngokuhambelana nokusebenza kwesixhobo kunye neemeko zokusingqongileyo. Umzekelo, kwindawo eqhelekileyo, igrisi inokutshintshwa kube kanye emva kweenyanga ezintandathu, kwaye phantsi kweemeko ezibandayo, inokufinyezwa kuzo zonke iinyanga ezi-3 ukuya kwezi-4 ukuqinisekisa ukuba ukusebenza kwegrisi kuhlala kukwimeko entle.
Ukutywinwa okulungileyo kunokuthintela umoya obandayo, ukufuma kunye nokungcola kwi-bearing. Kwimozulu ebandayo, ungasebenzisa izitywina eziphezulu zokusebenza, ezifana ne-double lip seal okanye i-labyrinth seal. Izitywina ezinemilebe ephindwe kabini zinemilebe yangaphakathi nangaphandle yokuthintela ngcono izinto zangaphandle kunye nokufuma ngaphandle. Iimpawu zeLabyrinth zinesakhiwo setshaneli esiyinkimbinkimbi esenza kube nzima ukuba izinto zangaphandle zingene kwi-bearing. Oku kunciphisa umonakalo ekuthwaleni isakhiwo sangaphakathi esibangelwa ukwandiswa kwe-icing yamanzi, kunye nokuthintela ukungena kokungcola okubangelwa ukunyuka kokuthwala.
Umphezulu wokuthwala unokufakwa ngengubo ekhuselayo, njengepeyinti ye-antirust okanye i-coating low-temperature yokukhusela. Ipeyinti ye-Antirust inokuthintela ukuthwala ukugqwala kwiimeko ezibandayo okanye ezimanzi, ngelixa iingubo ezikhuselayo ze-cryogenic zinokunciphisa imiphumo yokutshintsha kweqondo lokushisa kwizinto ezithwala. Iingubo ezinjalo zisebenza njengomgcini wokukhusela umphezulu wokuthwala ukhukuliseko oluthe ngqo kwiindawo eziphantsi kweqondo lokushisa kunye nokunceda ukunciphisa utshintsho kwizinto eziphathekayo ngenxa yokutshintsha kweqondo lokushisa.
Izixhobo zokuzifudumeza
Ukufudumeza iyunithi yonke ngaphambi kokuba uyiqalise yindlela esebenzayo. Kwezinye izixhobo ezincinci, zinokufakwa kwi "Conservatory" ixesha elithile ukuvumela ubushushu obuthwele ukuba buphakame. Kwizixhobo ezinkulu, ezifana ne-cranes ezinkulu ezithwele, zingasetyenziselwa ukongeza iteyiphu yokushisa okanye i-fan eshushu okanye ezinye izixhobo zokutshisa i-prehearing part. Ukushisa kwe-preheating kungalawulwa ngokubanzi malunga ne-10 - 20 ° C, enokwenza ukuba iindawo ezithweleyo zande kwaye zibuyele kwi-clean clearance, ngelixa kunciphisa i-viscosity yegrisi, ehambelana nokuqala kakuhle kwezixhobo.
Kwezinye iibheringi ezinokuthi zihlakazwe, i-oyile yokuhlamba i-preheating yindlela efanelekileyo. Beka iibheringi kwioli yokuthambisa ifudunyezwe kwiqondo lokushisa elifanelekileyo, ukwenzela ukuba iibheringi zifudumale ngokulinganayo. Le ndlela ayigcini nje ukwandisa izinto zokuthwala, kodwa ivumela i-lubricant ukuba ingene ngokupheleleyo kwi-clean yangaphakathi yokuthwala. Ukushisa kweoli ye-preheated ngokuqhelekileyo malunga ne-30 - 40 ° C, ixesha linokulawulwa ngokuhambelana nobukhulu bokuthwala kunye nezinto eziphathekayo kunye nezinye izinto malunga ne-1 - 2 iiyure, ezinokuphucula ngokufanelekileyo ukuthwala kwimozulu ebanda ukuqala ukusebenza.

Nangona ukubanda kuzisa iingxaki ekuthwaleni, kunokwakha umgca wokukhusela oqinileyo ngokukhetha igrisi efanelekileyo, ukutywinwa kunye nokukhusela kwangaphambili. Oku akuqinisekisi kuphela ukusebenza okuthembekileyo kweebheringi kwiqondo lokushisa eliphantsi, ukwandisa ubomi babo, kodwa nokukhuthaza uphuhliso oluzinzileyo lweshishini, ukwenzela ukuba i-TP ikwazi ukuhamba ngokuzola ukuya kuhambo olutsha lwezoshishino.
