Xa ukhetha ukuphindaphinda kwezixhobo zokufudumeza induction , ngaba kuyimfuneko ukubala?

When selecting the frequency of izixhobo zokufudumeza , ngaba kuyimfuneko ukubala?

Ukhetho lwefrikhwensi yangoku ikakhulu kukukhetha uluhlu lwamaza, oko kukuthi, ukukhetha ibhendi yefrikhwensi, ungakhethi ngokuchanekileyo ixabiso lefrikhwensi ethile, ayinantsingiselo. Kufuneka kuthiwe i-8kHz kunye ne-10kHz ziyafana; I-25kHz kunye ne-3kHz nazo zingasetyenziswa ngokufanayo; kodwa i-8kHz kunye ne-30kHz, i-30kHz kunye ne-250kHz ayinakusetyenziswa ngokufanayo, ngenxa yokuba azikho kwibhendi yefrikhwensi efanayo, kukho umyalelo wokuhluka kobukhulu.

Ii-frequency ze-high-frequency kunye ne-intermediate-frequency-frequency-frequency device supply have rated frequencies kuwo onke amazwe. Ngokweemfuno zobubanzi bamacandelo ahlukeneyo kunye nobunzulu boluhlu olunzima, i-frequency efanelekileyo inokukhethwa ngokweThebhile 2-1 kunye neThebhile 2.2.

Itheyibhile 2-1 Ubunzulu obuqinileyo bomaleko wexabiso eliqhelekileyo lefrikhwensi

Ukuphindaphinda /kHz 250 70 35 8 2. 5 1. 0 0.5
Ubunzulu bomaleko owenziwe lukhuni /mm Incinci 0. 3 0. 5 0. 7 1. 3 2.4 3.6 5. 5
ubuninzi 1.0 1.9 2.6 5. 5 10 15 amashumi anambini
efanelekileyo 0. 5 1 1.3 2.7 5 8 11

 

① Kwi-250kHz , ngenxa yokuqhubela phambili kobushushu obukhawuleza kakhulu, idatha yangempela ingaba nkulu kunexabiso kwitheyibhile.

Itheyibhile 2-2 Ukukhethwa kokuphindaphinda ngexesha lokucinywa kwendawo ye-cylindrical parts

frequency Ubuncinci bedayamitha evumelekileyo Idayamitha ecetyiswayo frequency Ubuncinci bedayamitha evumelekileyo Idayamitha ecetyiswayo
/ kHz / mm / mm / kHz / mm / mm
1.0 55 160 35.0 9 26
2.5 35 100 70.0 6 18
8.0 19 55 250.0 3.5 10

Itheyibhile 2-3 yitshathi yokhetho lwangoku ngexesha lokwenziwa lukhuni kwamalungu eNkampani kaJohn Deere eMelika. Idayamitha yenxalenye kunye nobunzulu bomaleko oqina zidityanisiwe, kwaye ingasetyenziswa njengetshathi yereferensi yokukhethwa kwamaxesha angoku.

Qaphela: 1. Ubunzulu boluhlu oluqiniweyo kwitheyibhile luthathwa kwi-carbon steel medium-rolled medium-rolled medium, kwaye ubunzulu bomgangatho obunzima bulinganiswa kwi-45HRC.

2. Ubunzulu obuncinane bomaleko obunzima buxhomekeke kwizinto eziphathekayo zokufudumeza ixesha elifutshane (imeko yonyango lwangaphambi kokushisa), kunye nobunzulu bobunzulu bomaleko obunzima buxhomekeke kubunzima bezinto kunye neqondo lokufudumeza komhlaba.

3. A imele awona maza afanelekileyo; B imele amaza omoya afanelekileyo; C imele amaza omoya afanelekileyo.
