Iibheringi zeMpompo yamanzi yeMoto
I-bearing ye-automobile water pump shaft ibaluleke kakhulu kwinkqubo yokupholisa yesithuthi, idlala indima ebalulekileyo ekugcineni ubushushu obufanelekileyo bokusebenza kwenjini. Njenge-bearing echanekileyo kakhulu eyenzelwe ngokukodwa ukusetyenziswa kwe-automotive water pump, iqinisekisa ukuhanjiswa kwamandla ngaphandle komthungo ukusuka kwi-injini ukuya kwi-impeller ye-water pump, nto leyo echaphazela ngokuthe ngqo ukusebenza kakuhle kwenkqubo yokupholisa kunye nokuthembeka kwayo iyonke.
Xa kufikwa ekukhetheni izinto, ikheyiji ye-automotive water pump shaft bearing yenziwa nge-nylon eqinisiweyo 66—le nto ikhethwa ngenxa yokumelana kwayo nokuguguleka okugqwesileyo, ukunyamezelana nobushushu obuphezulu, kunye neempawu ezikhaphukhaphu, ezinegalelo kubomi obude be-bearing kunye nokusetyenziswa kwamandla okuncitshisiweyo.
Ngokuphathelele umsebenzi kunye nolwakhiwo, i-shaft bearing ye-automobile pump pump ineenzuzo ezintathu eziphambili ezenza ukuba ibaluleke kakhulu kwiinkqubo zokupholisa iimoto.
Okokuqala, umsebenzi wayo oyintloko kukuxhasa umngxuma wepompo yamanzi: ibamba umngxuma ngokukhuselekileyo endaweni yawo ngelixa ivumela ukujikeleza okuthe tye, idlulisela ngokufanelekileyo amandla okujikeleza ukusuka kwibhanti yenjini okanye kwinkqubo yegiya ukuya kwi-impeller. Olu dluliselo lubalulekile kwi-impeller ukuba ijikeleze i-coolant kuyo yonke injini, ichitha ubushushu obugqithisileyo kwaye ithintele ukugqithisa kakhulu.
Okwesibini, ibheri isebenzisa uyilo oludibeneyo—iindlela zomdyarho zihlala zitshintshwa ngqo kwishafti yempompo yamanzi, nto leyo esusa imfuneko yeringi yangaphakathi eyahlukileyo. Olu yilo lutsha alugcini nje ngokugcina indawo yokufaka ngaphakathi kwendibano yempompo yamanzi kodwa lukwaphucula amandla okuthwala umthwalo webheri, nto leyo eyenza ukuba imelane ngakumbi noxinzelelo loomatshini oluvela ngexesha lokusebenza kwenjini.
Okwesithathu, ezi bearing zinikezelwa njengeeyunithi ezitywiniweyo ezihlanganisiweyo. Izitywino ezihlanganisiweyo zibonelela ngomqobo oqinileyo kwi-coolant, ioyile yenjini, uthuli, kunye nezinye izinto ezingcolisayo, ziphepha ukubola kwe-bearing kunye nokungaphumeleli kwangaphambi kwexesha okubangelwa kukungcola kwe-lubricant.
Iimpawu eziphambili zeebheringi zemibhobho yamanzi yemoto zenzelwe ukuhlangabezana neemfuno eziqatha zeenkqubo zokupholisa iimoto. Ngokuphathelele izinto eziphathekayo, iringi engaphandle, izinto eziqengqelekayo, kunye nomphezulu wokudibana kwemibhobho zenziwe ngeentsimbi eziqinileyo ezisemgangathweni ophezulu. Ezi ntsimbi zidlula kwiinkqubo zonyango oluqatha lobushushu ukuze zifumane ubunzima obuphezulu, ukumelana nokuguguleka, kunye namandla okudinwa, ukuqinisekisa ukuba ibheringi inokumelana nokujikeleza okukhawulezayo kwexesha elide kunye neempembelelo zoomatshini.
Izitywini eziphambili ezingangeni manzi lolunye uphawu olubalaseleyo—zenziwe ngomatshini ochanekileyo ukuze zilingane kakuhle nendlu yeebheringi kunye neshaft, zibonelela ngokusebenza okungenako ukuvuza ixesha elide. Izitywini zenzelwe ukwamkela ukwanda kobushushu kunye nokuncitshiswa ngexesha lokuqalisa nokucima kwenjini, zigcina ukusebenza kwazo kokutywina kumanqanaba obushushu abanzi.
Ukongeza, iibheringi zithanjiswe kwangaphambili ngegrisi esebenza kakuhle enika ukumelana nobushushu, ukumelana namanzi, kunye nokumelana nokugqwala. Le grisi ikhethekileyo iqinisekisa ukuthambisa rhoqo nokuba kubushushu obuphezulu bokusebenza, inciphisa ukungqubana kunye nokuguguleka phakathi kwezinto eziqengqelekayo kunye neendlela zomdyarho.
Okokugqibela, umthamo womthwalo wezi bearing wenziwe ngobuchule ukuze ukwazi ukusingatha amandla abalulekileyo e-radial kunye ne-axial. Nokuba ngamandla e-radial avela kuxinzelelo lwebhanti okanye amandla e-axial avela ekusebenzeni kwe-impeller, ulwakhiwo lwe-bearing lwenziwe ngcono ukuze lusasaze la mandla ngokulinganayo, luthintele uxinzelelo lwendawo kunye nokwandisa ubomi benkonzo ye-bearing.
