Aikin aiki na magnetic famfo

Lokaci: 2021-05-11 Hits: 8

Magnetic magnetic ya ƙunshi sassa uku: famfo, magnetic drive, da mota. Maɓallin maɓallin keɓaɓɓiyar motsi ya ƙunshi rotor magnetic waje, rotor mai maganadisu na ciki da hannun riga mara keɓaɓɓu da maganadisu. Lokacin da motar ta fitar da rotor magnetic waje don juyawa, filin maganadisu zai iya shiga ratar iska da kayan da ba maganadisu ba, kuma ya fitar da rotor magnetic ciki wanda aka hada shi da impeller din don juyawa daidai, a fahimci rashin karfin watsawa mara lamba, kuma ya canza karfin hatimi cikin hatimi na tsaye. Saboda mashin din famfo da rotor maganadisu na ciki gaba daya an rufe su da jikin fanfo da hannun riga, matsalar "gudu, fitar ruwa, diga, da zubewa" an gama maganata gaba daya, kuma malalar wuta mai saurin kamawa, mai fashewa, mai guba da cutarwa a cikin an kawar da masana'antar tace abubuwa da sinadarai ta hanyar hatimin famfo. Haɗarin haɗarin aminci yana tabbatar da lafiyar jiki da ƙwaƙwalwa da samar da amintattun ma'aikata.

1. Tsarin aiki na magnetic famfo
N nau'i-nau'i na maganadisu (n shine ma lamba) ana haɗuwa akan rotors magnetic ciki da waje na mai motsa maganadisu a cikin tsari na yau da kullun, don haka sassan maganadisu sun zama cikakke haɗe da maganadisu da juna. Lokacin da sandunan maganadisu na ciki da na waje suke gaba da juna, ma'ana, kusurwar da ke canzawa tsakanin sandunan maganadisu biyu Φ = 0, kuzarin maganadisu na tsarin maganadisu shine mafi kankanta a wannan lokacin; lokacin da sandunan magnetic suka juya zuwa sandar guda, kusurwar da ke canzawa tsakanin sandunan maganadisu biyu Φ = 2π / n, ƙarfin maganadiso na tsarin maganadisu yana da yawa a wannan lokacin. Bayan cire ƙarfin waje, tunda sandunan maganadiso na tsarin maganadisu suna tare juna, ƙarfin maganadiso zai mayar da maganadisu zuwa mafi ƙarancin ƙarfin maganadisu. Sai maganadisu ya motsa, yana tuka rotor magnetic don ya juya.

2. Sigogin fasali
1. Magnet na dindindin
Maganganun dindindin da aka yi da ƙananan alamomin maganadisu suna da kewayon yanayin zafin jiki mai yawa (-45-400 ° C), ƙarfin aiki mai kyau, da kyakkyawan anisotropy a cikin filin magnetic. Demagnetization ba zai faru ba yayin da sandunan suke kusa. Yana da kyakkyawan tushe na magnetic filin.
2. Raba hannun riga
Lokacin da aka yi amfani da hannun riga mai kera karfe, hannun riga yana kewayawa a cikin sinusoidal alternating magnetic filin, kuma eddy current yana haifar da shi a cikin giciye wanda yake daidai da shugabancin layin karfin maganadisu kuma ya juye zuwa zafi. Maganar eddy current ita ce: inda Pe-eddy current; K-akai; n-ƙimar saurin famfo; T-magnetic watsa karfin juyi; F-matsa lamba a cikin spacer; D-diamita na ciki na spacer; juriya na abu; -matsi tenarfin ƙarfin ƙarfi. Lokacin da aka tsara famfo, ana ba da n da T ta yanayin aiki. Don rage eddy current ana iya yin la'akari dashi kawai daga ɓangarorin F, D, da sauransu. Hannun keɓaɓɓen hannun riga an yi shi ne da kayan ƙarfe da ƙarfe mai ƙarfi da ƙarfi, wanda ke da matukar tasiri a rage halin yanzu.

3. Gudanar da kwararar man shafawa mai sanyaya
Lokacin da famfon maganadisu ke gudana, dole ne a yi amfani da ƙaramin ruwa don wanka da sanyaya yankin tazarar annular tsakanin rotor magnetic ciki da hannun riga da keɓewa da kuma gogayya mai ɗaukar nauyi. Gudun gudana na mai sanyaya yawanci 2% -3% na ƙirar ƙirar ƙirar famfo. Yankin jujjuya tsakanin rotor magnetic ciki da hannun riga mai kerawa yana haifar da zafi mai yawa saboda igiyoyin ruwa masu kyau. Lokacin da mai sanyaya abu bai isa ba ko kuma rami mai ɗaci ba santsi ko toshewa ba, ƙarancin matsakaici na matsakaici zai kasance sama da yanayin zafin aiki na dindindin maganadiso, kuma rotor magnetic ciki zai rasa maganadisu da sannu a hankali kuma motsin maganadisu zai kasa. Lokacin da matsakaici shine ruwa ko ruwa mai ruwa, zazzagewar zafin jiki a yankin annulus za'a iya kiyaye shi a 3-5 ° C; lokacin da matsakaici shine hydrocarbon ko mai, za a iya kiyaye hauhawar zafin a yankin annulus a 5-8 ° C.

4. Zaman zamiya
Abubuwan da ake amfani da su na famfo na magnetic pampora zane ne, wanda aka cika su da polytetrafluoroethylene, kayan aikin injiniya da sauransu. Saboda kayan aikin injiniya suna da ƙwarin zafi mai kyau, juriya ta lalata, da juriya na gogayya, ƙyallen maɓuɓɓuka na magnetic yawanci ana yin su ne da kayayyakin injiniya. Saboda kayan aikin injiniya suna da rauni sosai kuma suna da ƙaramar haɓaka, ƙarancin ɗaukar nauyi bazai zama ƙarami ba don kauce wa haɗarin rataye.
Tunda matsatsin ruwan famfon magnetic yana lubricated ta hanyar isar da shi, ya kamata a yi amfani da abubuwa daban-daban don yin jigilar bisa ga kafofin watsa labarai da yanayin aiki.

5. Matakan kariya
Lokacin da sashin da ke motsa magnetic drive ke gudana a karkashin obalo ko rotor ya makale, babban kuma bangarorin da ke motsa na maganadisu zasu zame kai tsaye don kare famfon. A wannan lokacin, maganadisu na dindindin a kan magnetic actuator zai haifar da asara mai lalacewa da asarar maganadisu a ƙarƙashin aikin maɓallin magnetic na rotor mai aiki, wanda zai haifar da zafin jiki na dindindin maganadisu ya tashi kuma magnetic mai aiki da maganadisu ya zame ya gaza .
Uku, fa'idojin magnetic famfo
Idan aka kwatanta da famfunan centrifugal waɗanda suke amfani da hatimai na inji ko marufi masu ɗaukewa, famfunan magnetic suna da fa'idodi masu zuwa.
1. A famfo shaft canje-canje daga wani tsauri hatimi zuwa rufaffiyar tsaye tsaye, gaba daya guje wa matsakaici yayyo.
2. Babu buƙatar shafa mai mai sahihi da sanyaya ruwa, wanda ke rage yawan kuzari.
3. Daga watsawa zuwa hada syncronous ja, babu lamba da gogayya. Yana da ƙarancin amfani da ƙarfi, ƙwarewa mai ƙarfi, kuma yana da sakamako mai ƙyama da rage jijjiga, wanda ke rage tasirin rawar motsi a kan famfon magnetic da kuma tasirin motar yayin da famfon ya auku cavitation vibration.
4. Lokacin da aka cika nauyi, rotors na magnetic ciki da na waje yana zamewa kaɗan, wanda ke kiyaye motar da famfo.
Hudu, kiyayewa kan aiki
