Excavator zvikamu EC55 mutyairi wekuchengetedza kiyi inotenderera solenoid valve coil

Basa rekoiri

1. Ikozvino-blocking effect: Iko-self-induced electromotive simba muinductor coil nguva dzose inopesana nekuchinja kwezvino mukoiri. Iyo inductance coil ine inovharira mhedzisiro pa AC ikozvino, uye saizi yekuvharisa iyo inonzi inductance xl, uye iyo unit ndeye ohm. Hukama hwayo ne inductance L uye AC frequency F ndeye xl = 2πfl. Inductors inogona kunyanya kukamurwa kuita yakakwira-frequency choke coils uye yakaderera-frequency kukachidza makoiri.

2. Tuning uye frequency kusarudzwa: lc tuning circuit inogona kuumbwa nekubatanidza inductance coil uye capacitor yakafanana. Kureva kuti, yakasikwa oscillation frequency f0 yedunhu yakaenzana nefrequency f yeiyo isiri-inochinjisa chiratidzo, saka inductive reactance uye capacitive reactance yedunhu zvakare yakaenzana, saka iyo electromagnetic simba oscillates kumashure nekudzoka mune inductance uye. capacitance, inova resonance phenomenon yelc circuit. Pa resonance, iyo inductive reactance uye capacitive reactance yedunhu yakaenzana uye yakatarisana. Iko inductance yehuwandu hwemazuva ano muchiuno ndiyo idiki, uye ikozvino ndiyo yakakura (ichireva AC chiratidzo neF = "F0"). Iyo lc resonant circuit ine basa rekusarudza frequency, iyo inogona kusarudza iyo AC siginecha ine imwe frequency F.

Nezvekufambiswa kwecoil, nei coil yemhangura iri nani pane aluminium coil? Chokutanga pane zvose, maererano nekugadzirisa, conductivity yealuminium yakaderera kupfuura yemhangura. Kuti uenderane nemakoiri emhangura, aluminiyamu magineti waya dzingada yakakura muchinjikwa chikamu kuitira kuti vagokwanisa kupa chiyero chakafanana che conductivity. Kureva kuti, kana zvichienzaniswa nekoiri yemhangura yehukuru hwakafanana, ronda rekumonereka newaya yealuminium rinoda huwandu hwakawanda.

Chechipiri, maererano nemakemikari zvivakwa, iyo oxidation mwero wealuminium inokurumidza kupfuura yemamwe simbi. Kana aruminiyamu poda inoratidzwa kumhepo, ichave yakasvibiswa zvachose mumazuva mashoma, ichisiya hupfu chena hwakanaka. Naizvozvo, kuti ugadzire kubatanidza kwakaringana kuti uve nechokwadi chekufambisa kwakanaka, zvinodikanwa kubaya iyo oxide layer yealuminium electromagnetic waya kudzivirira kumwe kusangana pakati pealuminium nemhepo. Chekupedzisira, kubva pamaonero ekuita mari, aluminium coil ine mashandiro akafanana inoda mamwe majana uye waya dzakakura dhayamita, iyo inodhura uye isingadhuri pane coil yemhangura.
