Ukuhlaziywa kwe-demagnetization kazibuthe unomphela kupompo kazibuthe

Ungayivimba kanjani i-demagnetization yeuzibuthe unomphelaempompini kazibuthe, khona-ke kufanele siqale sihlaziye izizathu zokuthi kungani uzibuthe demagnetization, ezingahlukaniswa zibe yizimo ezilandelayo: 

1. Izinga lokushisa lokusebenzisa alinangqondo.

2. Ukusebenza kwekhanda eliphansi isikhathi eside.

3. Amapayipi awafaniswe ngendlela engafanele.

4. Ukuguga kwe-sliding bear akushintshwa ngesikhathi.

5. Iphampu kazibuthe igijima ingenzi lutho.

6. Amapayipi okufaka amaphampu namapayipi aphumayo avaliwe.

7. Izingxenye ze-rotor ziminyaniswe ngendlela engavamile.

8. I-Cavitation phenomenon.

 

Kusukela kulezi zizathu ezingenhla, singabona ukuthi izinga lokushisa yisizathu esiyinhloko esithinta ukukhishwa kazibuthe kwamagnetic.

Ingabonakala ku-demagnetization curve ofmagnets:

Lapho izinga lokushisa lidlula i-150 ℃, evamileI-Neodymiun Magnetsizongena ekulahlekeni kwe-torsion okungenakuhlehliswa;

Lapho izinga lokushisa lingaphezu kuka-250 ℃, omagnethi bezinto ezivamile ze-SmCo bazongena ekulahlekelweni okungenakuhlehliswa.

Lapho izinga lokushisa lingaphezu kuka-350 ℃, i-Ikhwalithi ephezulu ye-SmCo Magnetizongena ekulahlekeni okungenakuhlehliswa.
