Ifanele CAT Carter 2522237 excavator izesekeli valve solenoid 252-2237 24V

I-valve ye-solenoid elinganayo

Isebenza kanjani:

Zonke izingxenye zevalvu ye-solenoid ziyikhoyili kagesi ngokwengxenye kagesi, okungukuthi, i-inductor. Lapho i-inductor inikezwa isignali kagesi, inkambu ye-electromagnetic ekhiqizwe i-current izokwenza umgogodla we-valve unyakaze futhi ibone ukuguqulwa kwamapharamitha alawulwayo.
Ukuhlonza ikhwalithi:
Ikhoyili ngayinye ye-electromagnetic inenani eligxilile lokumelana no-R, kodwa le R ayikwazi ukuba "0" noma "∞", uma u-R= "0" ebonisa isifunda esifushane sangaphakathi: lapho u-R= "∞" ebonisa isekethe evuliwe yangaphakathi; nge
Ukumelana kwekhoyili endlini akukwazi ukuba "0". Uma izimo ezingenhla zingahlangatshezwana nazo futhi i-valve ye-solenoid ingasebenzi, kungase kube ukuthi okokufaka kwesignali akulungile noma umgogodla we-valve ubambekile.

Inzwa yokucindezela

Isebenza kanjani:

Ngenzwa yokucindezela enezintambo ezintathu, ingaqondwa njenge-potentiometer enezintambo ezintathu noma i-resistor eguquguqukayo, ngokuvamile enezela i-voltage engu-5V emigqeni emibili (umugqa ongu-1 nemigqa emi-3), futhi uma inani elilinganiselwe lishintsha, i-voltage umugqa omaphakathi (imigqa emi-2) iyashintsha phakathi kuka-0 no-5V.

Ukuhlonza ikhwalithi:
1. Khipha umugqa ophakathi, shintsha isignali elinganisiwe, sebenzisa i-multimeter ukuze ulinganise ukuthi i-voltage yomugqa ophakathi (imigqa emi-2) iyashintsha yini ngesignali elinganisiwe.
2. Yeqa inzwa ngaphandle kwephutha

Umgomo wokusebenza we-proportional electromagnetic control valve wethulwa

Isekelwe kumgomo we-valve yokuvala i-solenoid: lapho amandla evaliwe, intwasahlobo icindezela umgogodla ngqo esihlalweni, okwenza i-valve ivale. Lapho ikhoyili inikwa amandla, amandla kazibuthe kagesi akhiqizwayo anqoba amandla asentwasahlobo futhi aphakamise umongo, ngaleyo ndlela avule ivalvu. I-proportional solenoid valve yenza izinguquko ezithile esakhiweni se-solenoid valve: yenza ibhalansi phakathi kwamandla asentwasahlobo namandla kazibuthe kagesi ngaphansi kwanoma iyiphi ikhoyili yamanje. Ubukhulu bekhoyili yamanje noma usayizi wamandla kazibuthe kagesi buzothinta ukushaywa kwe-plunger nokuvuleka kwevalvu, futhi ukuvuleka kwevalvu (ukugeleza) kanye nekhoyili yamanje (isignali yokulawula) kuwubudlelwane obuhle bomugqa. Direct acting proportional valve solenoid ageleza ngaphansi kwesihlalo. I-medium igeleza isuka ngaphansi kwesihlalo, futhi isiqondiso samandla siyafana namandla kazibuthe kagesi, futhi okuphambene namandla asentwasahlobo. Ngakho-ke, kuyadingeka ukusetha amanani okugeleza amakhulu namancane ahambisana nobubanzi bokusebenza (ikhoyili yamanje) esimweni sokusebenza. I-proportional solenoid valve ye-Drey fluid ivaliwe (NC, uhlobo oluvamise ukuvaleka) lapho amandla ecishiwe.
