Ngobuningi obukhulayo bebhizinisi lethu lokuhweba langaphandle eminyakeni yamuva, imboni yethu yabhekana nokushoda komthamo omkhulu engxenyeni yesibili yonyaka odlule. Ukuphendula lesi simo, isisekelo sethu sengeze isithando somlilo esimaphakathi esisha kulo nyaka.
Ukwakhiwa kwesithando esisha sekuzophela. Isithando somlilo esisha kulindeleke ukuthi senziwe ngoJuni 10 nonyaka. Ngemuva kwesithando somlilo esisha, umthamo waminyaka yonke kulindeleke ukuthi ukhule ngamathani ayi-2000.
Amathiphu:Isithando semvamisa esiphakathi luhlobo lwedivayisi yokuhambisa ugesi eguqula imvamisa yamandla ye-50 Hz AC ibe imvamisa ephakathi (300 Hz kuye ku-1000 Hz). Iguqula imvamisa yamandla wezigaba ezintathu i-AC ibe yimanje ngqo ngemuva kokulungiswa, bese iguqula i-current eqondile ibe yimvamisa yesikhathi esiphakathi eguquguqukayo ukuze inikeze imvamisa ephakathi eshintshashintshayo yamanje egeleza ngekhoyili ye-capacitor ne-induction, ikhiqiza imigqa yamandla kazibuthe amakhulu ikhoyili yokungeniswa, Futhi usike impahla yensimbi ku-coil ye-induction, ekhiqiza i-eddy yamanje enkulu entweni yensimbi.
Imvamisa yokusebenza yesithando somlilo esiphakathi nendawo (ngemuva kwalokhu esibizwa ngokuthi yi-intermediate frequency furnace) iphakathi kwe-50 Hz ne-2000 Hz, esetshenziselwa kakhulu ukuncibilikisa izinsimbi ezingezona ezensimbi nezinsimbi zensimbi. Uma kuqhathaniswa neminye imishini yokuphonsa, isithando somlilo esiphakathi nendawo sinezinzuzo zokusebenza okuphezulu kokushisa, isikhathi esifushane sokuncibilika, ukulahleka okuncane kwe-alloy element, izinto zokuncibilika okubanzi, ukungcoliswa kwemvelo okuncane, kanye nokulawulwa okunembile kokushisa nokwakheka kwensimbi encibilikisiwe.
Lolu hlobo lwe-eddy yamanje futhi lunezici ezithile zamaphakathi zamanje eziphakathi, okungukuthi, ama-electron wamahhala wokugeleza kwensimbi emzimbeni wensimbi ngokumelana nokukhiqiza ukushisa. Isigaba sesithathu sebhuloho esilawulwa ngokuphelele sisetshenziswa ukuguqula okushintshayo kube njengamanje. Isibonelo, isilinda sensimbi sifakwa kwikhoyili yokungeniswa ngokushintshana kwamanje kwemvamisa yaphakathi. Isilinda sensimbi ayixhumani ngqo nekhoyili yokungeniswa. Izinga lokushisa lekhoyili ngokwalo liphansi kakhulu, kepha ingaphezulu lesilinda liyafudumala libe bomvu noma lincibilike, Futhi ijubane lokubomvu nokuncibilika lingatholakala ngokulungisa imvamisa nesikhathi samanje. Uma isilinda sifakwa maphakathi nekhoyili, izinga lokushisa elizungeze isilinda liyafana, futhi ukufudumeza nokuncibilika kwesilinda akukhiqizi igesi eyingozi nokungcola kokukhanya okuqinile.
