Ifanelekile CAT Carter 2522237 excavator izincedisi solenoid valve 252-2237 24V

Ivalve ye-solenoid elinganayo

Ingaba isebenza kanjani:

Onke amacandelo evalvu ye-solenoid yikhoyili ye-electromagnetic ngokwecandelo lombane, oko kukuthi, i-inductor. Xa i-inductor inikwe umqondiso wombane, intsimi ye-electromagnetic eyenziwa ngoku iya kwenza i-valve core ihambe kwaye iqonde utshintsho lweeparamitha ezilawulwayo.
Ukuchongwa komgangatho:
Ikhoyili nganye ye-electromagnetic inexabiso elimiselweyo lokumelana no-R, kodwa le R ayinakuba ngu- "0" okanye "∞", xa i-R= "0" ibonisa isiphaluka esifutshane sangaphakathi: xa i-R= "∞" ibonisa i-circuit evulekile yangaphakathi; kunye
Ukuchasana kwekhoyili kwizindlu akunakuba "0". Ukuba le miqathango ingentla inokufezekiswa kwaye i-valve ye-solenoid ayisebenzi, mhlawumbi igalelo lomqondiso lingalunganga okanye i-valve core ibambelele.

Inzwa yoxinzelelo

Ingaba isebenza kanjani:

Kwi-sensor yoxinzelelo lweentambo ezintathu, inokuqondwa njenge-potentiometer yocingo-ntathu okanye i-resistor variable, ngokuqhelekileyo yongeza i-voltage ye-5V kwimigca emibini (umgca we-1 kunye nemigca emi-3), kwaye xa ixabiso elilinganisiweyo litshintsha, i-voltage umgca ophakathi (imigca emi-2) utshintsho phakathi kwe-0 kunye ne-5V.

Ukuchongwa komgangatho:
1. Khokela umgca ophakathi, utshintshe umqondiso olinganisiweyo, sebenzisa i-multimeter ukulinganisa ukuba i-voltage yomgca ophakathi (imigca emi-2) iyatshintsha kunye nomqondiso olinganisiweyo.
2. Wela inzwa ngaphandle kwempazamo

Umgaqo wokusebenza wevalvu yokulawula i-electromagnetic iyaziswa

Isekelwe kumgaqo we-solenoid on-off valve: xa amandla ecinyiwe, intwasahlobo icinezela i-core ngqo kwisihlalo, ibangela ukuba i-valve ivale. Xa ikhoyili yenziwe amandla, amandla e-electromagnetic awenziwayo ayoyisa amandla asentwasahlobo kwaye aphakamise undoqo, ngaloo ndlela avule ivalve. Ivalve ye-solenoid elinganayo yenza utshintsho oluthile kwisakhiwo sevalve ye-solenoid: yenza ibhalansi phakathi kwamandla asentwasahlobo kunye namandla ombane we-electromagnetic phantsi kwayo nayiphi na i-coil current. Ubungakanani bekhoyili yangoku okanye ubungakanani bamandla e-electromagnetic buya kuchaphazela i-plunger stroke kunye nokuvulwa kwevalvu, kunye nokuvulwa kwevalve (ukuhamba) kunye nekhoyili yangoku (uphawu lolawulo) lubudlelwane obufanelekileyo bomgca. Ivalve ye-solenoid esebenza ngokuthe ngqo ihamba phantsi kwesitulo. I-medium ingena isuka phantsi kwesihlalo, kwaye isalathiso samandla siyafana namandla ombane we-electromagnetic, kunye nesichasi samandla asentwasahlobo. Ngoko ke, kuyimfuneko ukuseta amaxabiso amakhulu kunye amancinci ahambelana noluhlu lokusebenza (coil current) kwimeko yokusebenza. Ivalve yeproportional solenoid ye-Drey fluid ivaliwe (NC, uhlobo oluqhelekileyo oluvaliweyo) xa umbane ucinyiwe.
