Magadzirirwo nekugadzira induction kupisa uye kudzima inductors?

Kudzima inductor chinhu chakakosha chekudziya chinoshandisa musimboti weeddy ikozvino kudzima pamusoro pezvikamu uye kusimbisa pamusoro. Kune marudzi akawanda ezvikamu zvekupisa kwepamusoro, uye maumbirwo awo akasiyana zvakanyanya. Nokudaro, dhizaini ye sensor yakasiyana. Kazhinji, saizi ye sensor inonyanya kutarisisa dhayamita, kureba, muchinjiko-chikamu chimiro cheiyo induction coil, inotonhorera nzira yemvura uye yekupfapfaidza gomba, nezvimwewo, uye dhizaini yayo.

1. Iyo dhayamita ye sensor

Chimiro cheinductor chinotarirwa maererano nehuwandu hwepamusoro hwechikamu chekupisa. Panofanira kunge paine imwe gaka pakati peiyo induction coil uye chikamu, uye inofanirwa kunge yakafanana kwese.

Paunenge uchipisa denderedzwa rekunze, dhayamita yemukati ye sensor Din = D0 + 2a; pakupisa gomba remukati, dhayamita yekunze ye sensor Dout = D0-2a. Ipo D0 iri dhayamita rekunze kana dhayamita remukati regomba rebasa, uye a ndiyo mukaha pakati pezviviri. Tora 1.5～3.5mm yezvikamu zveshaft, 1.5～4.5mm yezvikamu zvegiya, uye 1～2mm yezvikamu zvemukati megomba. Kana iyo yepakati frequency kudziyisa uye kudzima ikaitwa, gaka rakasiyana zvishoma. Kazhinji, shaft zvikamu 2.5 ~ 3mm, uye mukati mukati 2 ~ 3mm.

2. Kureba kwe sensor

Kureba kweinductor kunonyanya kutariswa zvinoenderana nesimba P0 yemidziyo yekudziya, iyo dhayamita D yebasa rekushanda uye yakatemwa chaiyo simba P:

(1) Kudziya kwekamwe-nguva yezvikamu zvipfupi shaft, kuitira kudzivirira kupisa kwemakona akapinza, kureba kweiyo induction coil kunofanirwa kunge kuri kushoma pane kureba kwezvikamu.

(2) Kana nzvimbo dzakareba dzeshaft dzichidziya uye dzakanyoroveswa munharaunda panguva imwe chete, kureba kweiyo induction coil ndeye 1.05 kusvika 1.2 nguva kureba kwenzvimbo yekudzima.

(3) Kana kureba kweiyo single-turn induction coil yakanyanya kukwirira, pamusoro peiyo workpiece ichadziyirwa zvisina kuenzana. Tembiricha yepakati yakakwira zvakanyanya kudarika tembiricha kumativi ese. Iyo yakakwira frequency, yakanyanya kujeka, saka kaviri-kutendeuka kana akawanda-kutendeuka induction coils anoshandiswa panzvimbo.

3. Muchinjikwa-chikamu chimiro cheiyo induction coil

Iyo induction coil ine akawanda muchinjikwa-sectional maumbirwo, akadai denderedzwa, sikweya, rectangular, ndiro mhando (kunze welded kutonhora mvura pombi), etc. Kana quenching nzvimbo yakafanana, kukotama kupinda rectangular cross-section induction coil ndiyo inonyanya kukosha. zvehupfumi, uye kupisa-permeable layer inofanana uye yakatenderera. The cross-section ndiyo yakaipisisa, asi iri nyore kukotama. Zvinhu zvakasarudzwa zvakanyanya machubhu endarira kana machubhu emhangura, ukobvu hwemadziro eiyo yakakwira frequency induction coil ndeye 0.5mm, uye yepakati frequency induction coil i1.5mm.

4. Nzira yekutonhora yemvura uye gomba rekupfapfaidza

Tichifunga kuti kupisa kunogadzirwa nekuda kwekurasikirwa kwemazuva ano eddy, chikamu chimwe nechimwe chinoda kutonhodzwa nemvura. Iyo pombi yemhangura inogona kunyoroveswa zvakananga nemvura. Chikamu chekugadzira ndiro yemhangura inogona kugadzirwa sandwich kana kunze welded copper yemhangura kuti iite mhepo inotonhora yemvura; high-frequency inoenderera mberi kana kuti panguva imwe chete kupisa kunotora kuzvitonhodza Panguva yekupfapfaidza kutonhora, dhayamita yegomba rekupfapfaidza remvura reiyo induction coil inowanzoita 0.8～1.0mm, uye yepakati frequency kupisa i1～2mm; kona yegomba rejekiseni remvura rekuenderera mberi kwekudziya uye kudzima induction coil ndeye 35°～45°, uye gomba kureba i3～5mm. Panguva imwecheteyo, maburi ekupisa uye kudzima maburi epfapfaidzo anofanirwa kurongeka muhurongwa hwakadzikama, uye kuparadzaniswa kwemakomba kunofanirwa kurongeka zvakaenzana. Kazhinji, iyo yakazara nzvimbo yemakomba ekupfapfaidza inofanirwa kuve idiki pane nzvimbo yepombi inopinza kuti ive nechokwadi chekuti pfapfaidzo yekupfapfaidza uye inlet pressure inosangana nezvinodiwa.

Izvo zvinofanirwa kucherechedzwa kuti kugadzirisa annular mhedzisiro yekudziya kwemukati gomba, ferrite (yakakwira-frequency kuomesa) kana silicon simbi (yepakati-frequency kuomesa) mapepa anogona kusungirirwa pane induction coil kugadzira gedhi-yakaita magineti, uye yazvino inofambiswa padivi pegeji remagineti ( Iyo yekunze layer ye induction coil) inoyerera nepakati. Kuti udzivise zvikamu izvo zvisingafanirwe kuomeswa kubva pakupisa, zvindori zvesimbi kana zvinyoro zvemagineti zvinogona kushandiswa kugadzira magineti pfupi-yedunhu mhete nhovo. Uye zvakare, panguva yekupisa kwemukati, mukaha pakati peiyo induction coil padhuze nekona yakapinza inofanira kuwedzerwa zvakakodzera kudzivirira kupisa kwenzvimbo.
