Inokodzera DH150-7 pilot solenoid valve coil yeDoosan excavator

1. Inductance XL

Saizi yeiyo inductive coil inovharira mhedzisiro pakutaurirana ikozvino inonzi inductance XL, uye iyo unit ndeye ohm. Hukama hwayo ne inductance L uye frequency yekukurukurirana F ndeye XL = 2πfL.

2. Quality factor Q

Hunhu hwemhando Q huwandu hwemuviri hunoratidza kunaka kwecoil, uye Q chiyero cheiyo inductive reactance XL kune yayo yakaenzana kuramba, ndiko kuti, Q = XL/R. we loop. Iyo q kukosha kweiyo coil ine hukama neDC kuramba kwemutyairi, iyo dielectric kurasikirwa kweskeleton, kurasikirwa kunokonzerwa nenhovo kana simbi core, pesvedzero yeakanyanya frequency ganda maitiro uye zvimwe zvinhu. Iyo q kukosha kwekoiri kazhinji makumi kusvika kumazana.

3. Distributed capacitance

Iyo capacitance pakati pekutendeuka kwecoil, pakati pecoil nenhovo, uye pakati pecoil uye pasi ndiro inonzi distributed capacitance. Kuvapo kwekugovera capacitance kunoderedza kukosha kweQ kwekoiri uye kunokanganisa kugadzikana kwayo, saka iyo idiki iyo yakagoverwa capacitance yecoil, zviri nani.

1. Single layer coil

Single-layer coil inomonerwa papepa chubhu kana bakelite skeleton ine insulated waya imwe neimwe. Zvakadai sewave antenna coil mune transistor radio.

2. Muzinga wehuchi

Kana ndege yecoil yeronda isina kufambirana nenzvimbo inotenderera, asi ikapindirana neimwe maonero, rudzi urwu rwekoiri rwunodaidzwa kuti coil yehuchi. Uye nhamba yenguva iyo waya inokotama ichidzoka shure kana ichitenderera kamwe chete, iyo inowanzonzi nhamba yekupeta. Zvakanakira nzira yekumonera muzinga idiki vhoriyamu, diki yakagoverwa capacitance uye yakakura inductance. Mizinga yehuchi inomonerwa nemuchina wekumonereka nemuzinga. Iyo yakanyanya kupeta mapoinzi, idiki iyo yakagoverwa capacitance.

3. Ferrite core uye iron powder core coil

Iyo inductance yecoil ine hukama nekuti kune magineti musimboti kana kwete. Kupinza ferrite musimboti mugomba coil kunogona kuwedzera inductance uye kugadzirisa kunaka kwecoil.

4, coil yemhangura

Copper core coil inoshandiswa zvakanyanya mu ultrashort wave scale. Zviri nyore uye zvinoshanda kushandura inductance nekutenderedza kutaridzika kwemhangura musimboti mune coil.

5, color code inductor

Colour-coded inductor is inductor ine fixed inductance, uye inductance yayo inotaridzwa nenzira imwecheteyo yekupikisa, ine mhete yemavara sechiratidzo.

6, kukachidza coil

Iyo coil inorambidza kupinda kwemagetsi inonzi choke coil, iyo inogona kukamurwa kuita yakakwira frequency choke coil uye yakaderera frequency choke coil.

7. Deflection coil

Deflection coil mutoro weiyo inobuda nhanho yeTV scanning wedunhu. Deflection coil inoda yakakwira deflection sensitivity, yunifomu magineti, yakakwira Q kukosha, saizi diki uye mutengo wakaderera. Iyo yakakosha unit yejira rakarukwa rakakomberedzwa munzvimbo, rine makoramu maviri akatenderera, arc yekuruka uye inonyura arc (kana yekuwedzera mutsara).
