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.

Itheyibhile 2-3 Ukukhethwa kokuphindaphinda kwangoku kweengxenye ezilukhuni ze-induction

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.
