Iindaba - Iiparamitha eziphambili kunye neempawu zekhoyili yentsimbi eqengqelekayo eshushu: Ukusuka kwimveliso ukuya kwisicelo

Ngaphakathi kwishishini elikhulu lesinyithi,ikhoyili yentsimbi eqengqelekayo eshushuIsebenza njengezinto ezisisiseko, ezisetyenziswa kakhulu kwiindawo ezifana nokwakha, ukuvelisa oomatshini, kunye noshishino lweemoto. I-coil yentsimbi yekhabhoni, kunye nokusebenza kwayo okugqwesileyo kunye nokusebenza kakuhle kweendleko, iye yaba yinto ephambili kwimarike. Ukuqonda iiparameter kunye neempawu zayo eziphambili akubalulekile nje kuphela kwizigqibo zokuthenga kodwa kukwabalulekile ekwandiseni ixabiso lezinto.

Kwimeko yomsebenzi wefektri, ilungu labasebenzi elinxibe isigcina-ntloko esiluhlaza okwesibhakabhaka kunye nevesti eluhlaza okwesibhakabhaka libukele ngononophelo ikhoyili yentsimbi egoqwe ngobushushu iphakanyiswa yikreyini. Ezijikelezileyo kukho iikhoyili zentsimbi ezininzi ezigoqwe ngobushushu ezibekwe kakuhle. Iikhoyili zentsimbi ezinkulu kunye nendawo ecwangcisiweyo yefektri zibonisa ukuqina kunye nomgangatho wemveliso yentsimbi kunye nokucubungula i-环节, zigxininisa indawo ebalulekileyo yeekhoyili zentsimbi ezigoqwe ngobushushu njengezinto ezisisiseko kwimveliso yemizi-mveliso, kwaye zikwabonisa umoya oqinileyo nocwangcisiweyo ngexesha lemisebenzi yefektri.

Ikhoyili yentsimbi ye-ASTM A36

Ukuveliswa kweekhoyili zentsimbi yekhabhoni kuqala kwiikhoyili yentsimbi yekhabhoniumzi-mveliso, apho iibhilethi zicutshungulwa zibe ziikhoyili zeenkcukacha ezithile ngenkqubo yokuqengqeleka eshushu kakhulu. Umzekelo,Ikhoyili yentsimbi ye-ASTM A36ludidi lwentsimbi olusetyenziswa rhoqo oluchazwe yimigangatho ye-American Society for Testing and Materials (ASTM) kwaye lufunwa kakhulu kwicandelo lobunjineli bokwakha nolwakhiwo. I-ASTM A36 coil inamandla okuvelisa angama-≥250 MPa kunye namandla okutsalwa angama-400-550 MPa, kunye nokuqina okugqwesileyo kunye nokudityaniswa, ukuhlangabezana neemfuno zokuthwala umthwalo kunye noqhagamshelo lwezakhiwo ezinkulu ezifana neebhulorho kunye neefreyimu zefektri. Ukwakheka kwayo kweekhemikhali kudla ngokugcina umxholo wekhabhoni ungaphantsi kwe-0.25%, kulungelelaniswa ngokufanelekileyo amandla kunye nokuqina ngelixa kuthintelwa ukubhitya okunxulunyaniswa nomxholo wekhabhoni ogqithisileyo.

Ngokwembono yeparameter, ubukhulu, ububanzi, kunye nobunzima bekhoyili zizibonakaliso ezibalulekileyo zokuvavanya ukusebenza kweekhoyili zentsimbi ezigoqwe ngobushushu. Ubukhulu obuqhelekileyo buqala kwi-1.2 ukuya kwi-25.4 mm, ngelixa ububanzi bunokudlula i-2000 mm. Ubunzima bekhoyili bunokuguqulelwa ngokwezifiso, buhlala buqala kwiitoni ezili-10 ukuya kwezingama-30. Ulawulo oluchanekileyo lobukhulu aluchaphazeli kuphela ukusebenza kakuhle kokucubungula kodwa lukwachaphazela ngokuthe ngqo ukuchaneka kwemveliso yokugqibela. Umzekelo, ukunyamezela ubukhulu beekhoyili zentsimbi ezigoqwe ngobushushu ezisetyenziswa kwimveliso yeemoto kufuneka kulawulwe ngokungqongqo ngaphakathi kwe-±0.05 mm ukuqinisekisa ubungakanani obuhambelanayo beendawo ezifakwe isitampu.
