Menene fa'idodin famfon maganadisu mai zafin jiki? ?

  Famfo mai zafi mai zafi wani nau'i ne na watsa wutar lantarki mara lamba ta hanyar injin maganadisu (Magnetic coupling), ta yadda madaidaicin hatimin ya maye gurbin hatimi mai ƙarfi, ta yadda famfon ɗin ba shi da ɗigo gaba ɗaya. Tun da famfo shaft da na ciki Magnetic na'ura mai juyi gaba daya an rufe ta da famfo jiki da kuma keɓe hannun riga, da yayyo matsala an warware gaba daya, da aminci hadarin flammable, fashewa, mai guba da kuma cutarwa kafofin watsa labarai yabo ta cikin famfo hatimin a cikin refining da sinadaran. an kawar da masana'antu.

Haɗin famfo

Babban zafin jiki na maganadisu ya ƙunshi sassa uku: famfo mai sarrafa kansa, injin maganadisu da mota. Maɓalli mai mahimmanci, injin maganadisu, ya ƙunshi na'urar maganadisu na waje, na'urar maganadisu ta ciki da kuma hannun riga mara magana.

1. Magnets na dindindin:
Maɗaukaki na dindindin da aka yi da kayan aiki suna da kewayon zafin aiki mai faɗi (-45-400 ° C), ƙarfin tilastawa mai ƙarfi, anisotropy mai kyau a cikin jagorar filin maganadisu, kuma babu demagnetization zai faru lokacin da sanda ɗaya ke kusa da juna. Wani nau'i ne na Mahimmin tushen filin maganadisu.

2. Warewa hannun riga:
Lokacin da aka yi amfani da na'urar sarari ta ƙarfe, sararin samaniya yana cikin wani filin maganadisu na sinusoidal, kuma ana haifar da eddy current akan wani sashe daidai gwargwado ga layin ƙarfin maganadisu kuma ya koma zafi.

3. Sarrafa mai sanyaya mai yawo
Lokacin da babban zafin famfo na maganadisu ke gudana, dole ne a yi amfani da ƙaramin adadin ruwa don juyewa da kwantar da yankin tazarar zobe tsakanin na'urar maganadisu na ciki da keɓewar hannun riga da ɓangarorin biyu na ɗaukar hoto. Matsakaicin adadin mai sanyaya yawanci shine 2% -3% na ƙimar ƙirar ƙira na famfo, kuma yankin ratar zobe tsakanin na'urar maganadisu na ciki da keɓewar hannun riga yana haifar da zafi mai zafi saboda igiyoyin ruwa. Lokacin da ruwa mai sanyaya sanyi bai isa ba ko rami mai ɗumi bai san santsi ko toshe ba, zafin matsakaicin zai kasance sama da yanayin zafin aiki na maganadisu na dindindin, ta yadda na'urar maganadisu ta ciki za ta yi hasarar magnetism a hankali kuma injin maganadisu zai kasance. kasa. Lokacin da matsakaici shine ruwa ko ruwa na tushen ruwa, ana iya kiyaye yanayin zafi a cikin yankin annulus a 3-5 ° C; lokacin da matsakaici shine hydrocarbon ko mai, ana iya kiyaye yanayin zafi a yankin annulus a 5-8 ° C.

4. Haushi a fili
Kayayyakin Magnetic famfo zamiya bearings sun hada da impregnated graphite, cika PTFE, injiniya yumbu, da dai sauransu Saboda aikin injiniya yumbu da kyau zafi juriya, lalata juriya, da gogayya juriya, da zamiya bearings na Magnetic farashinsa yawanci sanya na injiniya yumbu.
Tun da injiniyoyin yumbura suna da ƙarfi sosai kuma suna da ƙaramin haɓaka haɓaka haɓakawa, ba da izinin ɗaukar nauyi ba dole ne ya zama ƙanƙanta don guje wa hatsarori na shaft.Tun da ɗimbin ɗimbin ɗimbin bututun magnetic zafin jiki suna lubricated ta matsakaicin jigilar kayayyaki, ya kamata a yi amfani da kayan daban-daban yi bearings bisa ga daban-daban kafofin watsa labarai da kuma yanayin aiki.
