Haum rau DH150-7 pilot solenoid valve coil ntawm Doosan excavator

1. Inductance XL

Qhov loj ntawm inductive coil qhov thaiv qhov cuam tshuam ntawm kev sib txuas lus tam sim no hu ua inductance XL, thiab chav tsev yog ohm. Nws kev sib raug zoo nrog inductance L thiab kev sib txuas lus zaus F yog XL = 2πfL.

2. Cov yam ntxwv zoo Q

Qhov zoo tshaj plaws Q yog lub cev muaj nuj nqis uas qhia txog lub kauj zoo, thiab Q yog qhov piv ntawm inductive reactance XL rau nws qhov sib npaug, uas yog, Q = XL / R .. Qhov ntau dua tus nqi ntawm lub kauj, qhov tsawg dua qhov poob ntawm lub voj. Q tus nqi ntawm cov kauj yog cuam tshuam nrog DC tsis kam ntawm tus neeg xyuas pib, qhov dielectric poob ntawm lub cev pob txha, qhov poob los ntawm cov ntaub thaiv npog lossis cov tub ntxhais hlau, kev cuam tshuam ntawm cov tawv nqaij ntau zaus thiab lwm yam. Q tus nqi ntawm lub kauj yog feem ntau kaum mus rau pua pua.

3. Distribution capacitance

Lub capacitance ntawm lem ntawm kauj, nruab nrab ntawm lub kauj thiab daim thaiv npog, thiab nruab nrab ntawm lub kauj thiab lub phaj hauv qab yog hu ua faib capacitance. Lub hav zoov ntawm kev faib capacitance txo qis Q tus nqi ntawm lub kauj thiab ua rau nws ruaj khov, yog li qhov me me ntawm cov khoom faib tawm ntawm lub kauj, qhov zoo dua.

1. Ib txheej coil

Ib txheej txheej txheej yog qhov txhab nyob ib ncig ntawm daim ntawv raj lossis lub pob txha pob txha nrog cov xov hlau insulated ib los ntawm ib qho. Xws li lub kav hlau txais xov nthwv dej hauv lub xov tooj cua transistor.

2. Honeycomb kauj

Yog hais tias lub dav hlau ntawm lub qhov txhab coil tsis yog sib npaug mus rau qhov chaw rotating, tab sis cuam tshuam nrog qee qhov kev xav, hom coil no hu ua honeycomb coil. Thiab tus naj npawb ntawm lub sij hawm cov hlau khoov rov qab thiab tawm thaum nws tig ib zaug, uas feem ntau hu ua tus naj npawb ntawm cov ntsiab lus folding. Qhov zoo ntawm honeycomb winding txoj kev yog me me ntim, me me faib capacitance thiab loj inductance. Honeycomb coils yog tag nrho cov qhov txhab los ntawm honeycomb winding tshuab. Cov ntsiab lus folding ntau dua, qhov me dua qhov faib cov peev txheej.

3. Ferrite core thiab hlau hmoov core coil

Lub inductance ntawm lub kauj muaj feem xyuam rau seb puas muaj ib tug hlau nplaum los yog tsis. Kev nkag mus rau ferrite core rau hauv hollow coil tuaj yeem ua rau inductance thiab txhim kho qhov zoo ntawm cov kauj.

4, tooj liab core coil

Copper core coil yog siv dav hauv ultrashort yoj nplai. Nws yog ib qho yooj yim thiab siv tau los hloov cov inductance los ntawm kev tig cov kev taw qhia ntawm cov tub ntxhais tooj liab hauv lub kauj.

5, xim code inductor

Xim-coded inductor yog ib qho inductor nrog ib qho inductance ruaj khov, thiab nws cov inductance yog cim nyob rau hauv tib txoj kev uas tsis kam, nrog lub nplhaib xim raws li lub cim.

6, choke coil (cuam tshuam)

Lub kauj uas txwv tsis pub dhau ntawm hluav taws xob yog hu ua choke coil, uas tuaj yeem muab faib ua cov choke choke coil thiab tsis tshua muaj choke coil.

7. Deflection kauj

Deflection kauj yog lub load ntawm cov zis theem ntawm TV scanning Circuit Court. Deflection kauj yuav tsum muaj siab deflection rhiab heev, niaj hnub sib nqus teb, siab Q tus nqi, me me thiab tus nqi qis. Lub hauv paus ntawm knitted ntaub yog nkhaus nyob rau hauv qhov chaw, muaj ob lub voj voog, ib tug knitting arc thiab ib tug sinking arc (los yog extension kab).
