Lapho ukhetha imvamisa yemishini yokushisa yokungeniswa , ingabe kuyadingeka ukubala?

When selecting the frequency of imishini yokushisa yokufakelwa , kuyadingeka yini ukubala?

Ukukhethwa kwemvamisa yamanje ngokuyinhloko ukukhetha ububanzi befrikhwensi, okungukuthi, ukukhetha ibhendi yefrikhwensi, hhayi ukukhetha ngokunembile inani lemvamisa ethile, akusho lutho. Kufanele kushiwo ukuthi i-8kHz ne-10kHz ziyafana; I-25kHz ne-3kHz nazo zingasetshenziswa ngokufanayo; kodwa i-8kHz ne-30kHz, 30kHz kanye ne-250kHz ayikwazi ukusetshenziswa ngokufanayo, ngenxa yokuthi awekho kubhendi yefrikhwensi efanayo, kukhona ukuhleleka komehluko wobukhulu.

Amafrikhwensi wempahla yokuphakelwa kukagesi yamafrikhwensi aphezulu kanye namaza aphakathi anesilinganiso samafrikhwensi kuwo wonke amazwe. Ngokwezidingo zobubanzi bezingxenye ezihlukene kanye nokujula kwesendlalelo esiqinile, imvamisa efanele ingakhethwa ngokusho kweThebula 2-1 kanye neThebula 2.2.

Ithebula 2-1 Ukujula kwesendlalelo esiqinile senani elijwayelekile lokuvama

Imvamisa / kHz		250	70	35	8	2. 5	1. 0	0.5
Ukujula kwesendlalelo esiqinile/mm	Okuncane kakhulu	0. 3	0. 5	0. 7	1. 3	2.4	3.6	5. 5
	esiphezulu	1.0	1.9	2.6	5. 5	10	15	amashumi amabili nambili
	kahle	0. 5	1	1.3	2.7	5	8	11

① Ku-250kHz , ngenxa yokwenziwa kokushisa okushesha kakhulu, idatha yangempela ingaba nkulu kunenani elikuthebula.

Ithebula 2-2 Ukukhethwa kwemvamisa ngesikhathi sokucisha indawo yezingxenye ze-cylindrical

imvamisa	Ubuncane be-diameter obuvumelekile	Ububanzi obunconyiwe	imvamisa	Ubuncane be-diameter obuvumelekile	Ububanzi obunconyiwe
/ 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

Ithebula 2-3 yishadi lamanje lokukhetha imvamisa ngesikhathi sokwenziwa lukhuni kwezingxenye ze-John Deere Company e-United States. Ububanzi bengxenye nokujula kwesendlalelo esiqinile kuhlanganisiwe, futhi kungasetshenziswa njengeshadi eliyireferensi lokukhethwa kwefrikhwensi yamanje.

Ithebula 2-3 Ukukhethwa kwemvamisa yamanje yezingxenye eziqinile zokungeniswa

Amandla kagesi Izingxenye eziqinile zokungeniswa		isigaba	I-generator amandla esimo esiqinile			High frequency generator
		Amandla /kW	7 ~ 2000			5 -600
		Imvamisa / kHz	1	3	10	50 ~ 100	200;600	1000
Ububanzi / mm	Ukujula kwesendlalelo esiqinile/mm
I-W12	0.2 ubuncane 0.7						A	A B

Amandla kagesi Izingxenye eziqinile zokungeniswa		Elinye ikilasi IJ	Ukunikezwa kwamandla kagesi we-mechanical generator			High frequency generator
		Amandla /kW	7 – 2000			I-5-600

Qaphela: 1. Ukujula kongqimba oluqinile kuthebula kuthathwa ku-carbon steel medium roll rolled medium, futhi ukujula kongqimba oluqinile kukalwa ku-45HRC.

2. Ubuncane bokujula kongqimba oluqinile kuncike ezintweni ezibonakalayo zokushisa kwesikhathi esifushane (isimo sokwelashwa kwangaphambi kokushisa), futhi ukujula kongqimba okunzima kakhulu kuncike ekuqineni kwezinto kanye nezinga lokushisa elingaphezulu.

3. U-A umele imvamisa efaneleke kakhulu; U-B umele imvamisa efaneleke kakhulu; U-C umele imvamisa efaneleke kancane.
