Izingxenye ze-Excavator EC55 isikhiye sokuphepha somshayeli wekhoyili ezungezayo yevalve ye-solenoid

Umsebenzi wekhoyili

1. Umthelela wokuvinjwa kwamanje: Amandla e-electromotive azidalayo kukhoyili ye-inductor ahlala ephikisana noshintsho lwamanje kukhoyili. Ikhoyili ye-inductance inomphumela wokuvimba ku-AC yamanje, futhi usayizi womphumela wokuvimba ubizwa ngokuthi i-inductance xl, futhi iyunithi ithi ohm. Ubudlelwano bayo ne-inductance L kanye ne-AC frequency F yi-xl=2πfl. Ama-inductors angahlukaniswa kakhulu abe amakhoyili okuklinywa anemvamisa ephezulu kanye namakhoyili okuminyanisa anemvamisa ephansi.

2. Ukukhethwa kwe-Tuning kanye nemvamisa: i-lc tuning circuit ingakhiwa ngokuxhuma ikhoyili ye-inductance kanye ne-capacitor ngokuhambisana. Okusho ukuthi, imvamisa yemvelo ye-oscillation f0 yesekethe ilingana nemvamisa f yesiginali engashintshisani, ngakho-ke ukusabela kwe-inductive kanye nokusabela kwe-capacitive kwesekethe nakho kuyalingana, ngakho-ke amandla kazibuthe kagesi azulazula aye emuva naphambili ku-inductance futhi i-capacitance, okuyi-resonance phenomenon yesekethe ye-lc. Ku-resonance, i-inductive reactance kanye ne-capacitive reactance yesekethe kuyalingana futhi kuphambene. I-inductance yesamba samanje ku-loop incane kakhulu, futhi yamanje inkulu kakhulu (ibhekisela kusignali ye-AC eno-F = "F0"). Isekethe ye-lc resonant inomsebenzi wokukhetha imvamisa, engakhetha isignali ye-AC ngefrikhwensi ethile F.

Mayelana nokuhamba kwekhoyili, kungani ikhoyili yethusi ingcono kunekhoyili ye-aluminium? Okokuqala, ngokuya nge-conductivity, i-conductivity ye-aluminium iphansi kuneyethusi. Ukuze uhambisane namakhoyili ethusi, izintambo kazibuthe ze-aluminium zingadinga ingxenye enkulu yesiphambano ukuze zinikeze izinga elifanayo lokuhamba. Okusho ukuthi, uma kuqhathaniswa nekhoyili yethusi yobukhulu obufanayo, inxeba eliphendukayo elinocingo lwe-aluminium lidinga umthamo owengeziwe.

Okwesibili, ngokwezakhiwo zamakhemikhali, izinga le-oxidation le-aluminium lishesha kakhulu kunelezinye izinsimbi. Uma i-aluminium powder ivezwa emoyeni, izokhishwa ngokuphelele nge-oxidized ezinsukwini ezimbalwa, ishiye impushana emhlophe ecolekile. Ngakho-ke, ukuze wenze uxhumano olufanele ukuze kuqinisekiswe ukuhamba kahle, kuyadingeka ukubhoboza ungqimba lwe-oxide lwe-aluminium electromagnetic wire ukuvimbela ukuxhumana okuqhubekayo phakathi kwe-aluminium nomoya. Okokugcina, ngokombono wokonga imali, ikhoyili ye-aluminium esebenza ngendlela efanayo idinga amajika amaningi kanye nezintambo ezinkulu ezidayamitha, ezimba eqolo futhi ezonga kakhulu kunekhoyili yethusi.
