Active Magnetic hali

Kowa ya sani cewa da maganadiso ayan jawo hankalin karafa. Har ila yau daya maganadisu iya jawo hankalin sauran. Amma da hulda tsakanin su ba iyakance kawai ga janye, za su iya tare juna. A batu a sandunan da wani maganadisu - m sandunan jawo hankalin juna, da wannan sunan - a farkon. Wannan dukiyar suranta tushen duk Motors, da kuma quite m.

Har ila yau, akwai irin wannan abu a matsayin levitation da wani Magnetic filin, idan sanya a kan maganadisu abu (da ciwon kama iyakacin duniya tare da shi) freezes a cikin sarari. Wannan sakamako da aka amfani a yi a cikin abin da ake kira Magnetic hali.

Mene ne wani Magnetic hali

electromagnetic irin na'ura a wanda wani juyawa shaft (na'ura mai juyi) yana goyan bayan a kan keken rabo (stator) na Magnetic juyi sojojin, da ake kira Magnetic hali. Lokacin da inji shi ne a cikin aiki, shi ne ya rinjayi jiki sojojin da suka nemi su matsawa da axis. Don shawo kan su, mu sanye take da Magnetic hali kula da tsarin cewa na sa ido da kaya da kuma kai ikon kula da sigina Magnetic juyi. Maganadiso, bi da bi, karfi ko rauni sakamako a kan na'ura mai juyi, ajiye shi a tsakiyar matsayi.

Magnetic hali ne yadu amfani a masana'antu. Yana da m da wani iko injin turbin engine. Saboda babu gogayya, saboda haka, da bukatar yin amfani da lubricants, inji AMINCI ne ta ƙara da yawa sau kan. kusan babu lalacewa a gyara. Yana kuma inganta ingancin yi, kuma Yanã ƙãra yadda ya dace.

Active Magnetic bearings

Magnetic hali, inda karfi filin halitta da wani electromagnet, aka kira mai aiki. Electromagnets positional zubar a cikin hali stator, da na'ura mai juyi yana dauke da karfe shaft. A gaba dayan tsarin, wanda ya samar da da shaft riƙewa a naúrar, da ake kira mai aiki Magnetic levitation (Ila). Ya na da wani hadadden tsarin da kuma kunshi sassa biyu:

• Qazanta naúrar.
• lantarki kula da tsarin.

Basic abubuwa Ila

• Radial bearings. The na'urar, wanda yana a kan stator electromagnets. Sun rike da na'ura mai juyi. A cikin na'ura mai juyi akwai musamman farantin ferromagnetic. By dakatar da na'ura mai juyi ne ba a midpoint na lamba tare da stator. Inductive na'urori masu auna sigina saka idanu da 'yar alamar karkata a matsayi na na'ura mai juyi na maras sarari. A sakonni daga gare su don sarrafa karfi na maganadiso a ba batu mayar da ma'auni a cikin tsarin. Radial yarda ne 0.50-1.00 mm, da axial - 0.60-1.80 mm.

• Magnetic hali dirka aiki a cikin wannan hanya a matsayin tsagi. A na'ura mai juyi shaft da aka kulla dirka wanki, a garesu daga wanda aka shirya maganadiso gyarawa zuwa stator.
• Bearings harnesses aka tsara don rike da na'ura mai juyi a lokacin da na'urar ke a kashe, ko a gaggawa yanayi. A aiki, da karin Magnetic bearings ba amfani. The yarda tsakanin na'ura mai juyi shaft da biyu sau kasa da halin maganaɗisu hali. Fall arrester abubuwa suna harhada a kan tushe ballpoint na'urorin ko zamiya bearings.
• Control lantarki hada da wani na'ura mai juyi shaft matsayin masu auna sigina, converters kuma amplifiers. A dukan tsarin aiki a kan manufa na daidaitawa da Magnetic juyi a cikin kowane module na electromagnet.

M Magnetic hali irin

Magnetic bearings a kan m maganadiso - ne tsarin rike da na'ura mai juyi shaft, wanda ba a yi amfani da iko da kewaye ciki har da feedback. Levitation ne da za'ayi kawai a kudi na high-ƙarfi m maganadiso.

A hasara irin wannan m ne da bukatar yin amfani da wani inji tasha, wanda results a cikin samuwar gogayya da rage tsarin AMINCI. Magnetic mayar da hankali a cikin fasaha ji ba a aiwatar a cikin wannan makirci. Saboda haka, a yi da m hali da aka yi amfani da infrequently. Akwai jadadda mallaka model, kamar da dakatar da Nikolaev, wanda ya ba tukuna aka maimaita.

Tef a cikin dabaran hali

Kalmar "Magnetic dabaran hali" tana nufin Asb tsarin da aka yi amfani da ko'ina a cikin zamani motocin. Asb bearings halin a cewa da shi ya mai gina a ciki da dabaran gudun haska. Wannan haska ne mai aiki na'urar saka a cikin hali rufi. Ya dogara ne a kan Magnetic zobe a kan wanda sandunan m kashi, karanta da canji na Magnetic juyi.

Lokacin da hali rotates, akwai wani m canji a cikin Magnetic filin generated da Magnetic zobe. A haska daukawa fitar da rajista na canji, forming da siginar. Sa'an nan da alama ta shiga microprocessor. Mun gode wa aikin da tsarin irin na ABS da Esp. Riga su ne daidai abin hawa aiki. Esp ne ke da alhakin lantarki karfafawa, ABS iko da juyawa da ƙafafun, da matsa lamba matakin a cikin tsarin - da birki. Yana zaune a yanki da aiki na tuƙi tsarin, cikin hanzari a kaikaice shugabanci, kuma ya gyãra aiki na watsa da kuma engine.

Babban amfani da Asb hali ne iya sarrafa gudun juyawa ko a sosai low revs. A daidai wannan nauyi da kuma size sigogi an inganta cibiya, da hali taro da aka Sauki.

Yadda za a yi wani Magnetic hali

A sauki Magnetic qazanta hannuwansu yi karye. Ya aka ba su dace ga m amfani, amma shi a fili ya nuna yiwuwar Magnetic karfi. Wannan na bukatar da hudu neodymium maganadisu na wannan diamita, biyu maganadiso na dan kadan karami diamita shaft, misali wani sashi daga wani roba tube, da kuma abutment, misali gilashin rabin lita gilashi. karami da maganadiso da zafi-narke m ne a haɗe zuwa iyakar da tube haka kamar yadda su sami wani nada kamar.
