Iimpawu eziphambili zePneumatic solenoid valves
Ivalve ye-solenoid, njengesixhobo sevalve kumbhobho, sisixhobo esisetyenziselwa ukutshintsha indawo enqamlezayo{0}}yecandelo lepaseji kunye necala lokuhamba okuphakathi, kunye nokulawula intshukumo yendawo egqithisiweyo. Iimpawu zayo eziphambili zezi:
1. Ukuvuza kwangaphandle kuvaliwe ngokupheleleyo, ukuvuza kwangaphakathi kulula ukulawula, kwaye kukhuselekile ukusebenzisa. Ukuvuza kwangaphakathi nangaphandle kweevalvu yenye yezinto zokhuseleko{2}}kufakelo lwesiza. Ezinye iivalvu, ezifana{4}}neevalvu ezizilawulayo, zihlala zandisa isiqu sevalve kwaye zilawule ukujikeleziswa okanye intshukumo yondoqo wevalve ngombane, ipneumatic, okanye ihydraulic actuators. Oku kufuna ukusonjululwa kwengxaki yokuvuza kwangaphandle kwetywina eliguquguqukayo lesikhondo sevalvu ngenxa-yexesha elide lokusebenza. Ivalve yesolenoid isebenza ngokufaka amandla ombane kumbindi wentsimbi otywinwe kumkhono wokuzihlukanisa wemagnethi. Akukho sitywina esiguqukayo, ngoko ke ukuvuza kwangaphandle kuthanda ukuvaleka. Umzekelo, ngenxa yolawulo olulinganiselweyo lwetorque yeevalvu zombane, ziqhelene nokuvuza kwangaphakathi kwaye zisenokwaphula nentloko yesikhondo sevalve. I-valve ye-solenoid inesakhiwo esilula, ukutywinwa okuthembekileyo, kwaye kulula ukulawula ukuvuza kwangaphakathi.

Kuba yenza{4}}isekethi ezimeleyo, iphendula ngovakalelo kunezinye iivalvu zolawulo oluzenzekelayo. -Ikhoyili eyilwe kakuhle yevalve ye-solenoid isebenzisa amandla aphantsi kakhulu kwaye iyimveliso egcina amandla{7}. Ngokusebenzisa ilungiselelo lesiphaluka esifanelekileyo, kunokufezekiswa kwakhona ukuba indawo ye-valve inokugcinwa ngokuzenzekelayo nje ngokubangela isenzo, kwaye ayisebenzisi amandla phantsi kweemeko eziqhelekileyo. Eyona nzuzo inkulu yeevalvu ze-Pneumatic solenoid ilele kwimilinganiselo yangaphandle encinci, engagcini nje ngokugcina indawo kodwa ilula kwaye iyathandeka.
Qwalasela.
4. Ulungelelwaniso lokuchaneka kolawulo lulinganiselwe, kwaye alusebenzi kumajelo athile. Iivalvu ze-solenoid zomoya zihlala zineendawo ezimbini kuphela: zivulekile kwaye zivaliwe. Ivalve ingaba kwizikhundla ezibini ezigqithisileyo kwaye ayinakho ukulungelelaniswa ngokuqhubekayo (zininzi iimbono ezintsha ezizama ukutyhutyha, kodwa zonke zisekwinqanaba lovavanyo kunye nenqanaba lokusebenzisa isilingo). Ngoko ke, ukulungiswa okuchanekileyo kuxhomekeke kwimida ethile. Ivalve ye-solenoid inemfuno ephezulu kakhulu yokucoceka kwendawo. Ayifanelanga imidiya equlathe amasuntswana. Ukuba kukho ukungcola, kufuneka kuhluzwe kuqala. Ukongezelela, ngenxa yokungasebenzi kwemithombo yeendaba, uluhlu olusebenzayo lwe-viscosity yeendaba luncinci.
5. Iimodeli ezahlukeneyo kunye nezicelo ezibanzi. Nangona iivalvu ze-solenoid ze-Pneumatic zineentsilelo zendalo, izibonelelo zazo zisabonakala kakhulu. Ke ngoko, ziyilelwe kwiimveliso ezininzi ezahlukeneyo ukuhlangabezana neemfuno ezahlukeneyo kwaye zinosetyenziso olubanzi kakhulu. Inkqubela phambili yetekhnoloji yevalvu ye-solenoid ikwagxile kwindlela yokoyisa iintsilelo zendalo kunye nendlela yokuphucula izibonelelo zendalo. Ukususela kumbono womgaqo wokusebenza, urhulumente, kunye neempawu ze-Pneumatic solenoid valves, isakhiwo se-Pneumatic solenoid valves silula, kwaye inkqubo yokusebenza ayinzima. Ngethuba nje uyilo lunengqiqo kwaye umsebenzi unokuthenjwa ngexesha lokusetyenziswa okuqhelekileyo, akukho ngxaki ngokubanzi. Ngaphezu koko, xa kusetyenziswa ngokuqhelekileyo, ekubeni kungekho zintlantsi okanye amaqondo obushushu ayingozi aveliswayo, amathuba okubangela ugqabhuko-dubulo luncinane kakhulu. Nangona kunjalo, kwimeko ephosakeleyo, ngenxa yokungabikho kokhuseleko oluyimfuneko, ukuba kunokwenzeka ukuba i-valve ye-solenoid eyenza ingozi yokuqhuma iya kunyuka kakhulu.
Ii. Uwugwebe njani uMgangatho weValve ye-electromagnetic
Umgangatho wevalvu ye-electromagnetic ixhomekeke ikakhulu kwimiba emibini: ikhoyili kunye nomzimba wevalvu. Ngoko ke, uvavanyo kufuneka lugxininise kakhulu kule miba mibini. Ungafumana umbane we-24V kwaye uqhagamshele kwikhoyili. Ukuba unokuva isandi, kubonisa ukuba zombini i-coil kunye ne-valve core ye-solenoid valve iyinto eqhelekileyo kwaye inokuzibandakanya ngokuqhelekileyo. Emva koko khangela ukuba kukho nakuphi na ukuvuza. Ukuba kukho umthombo wegesi, kungcono ukudibanisa ngqo umthombo wegesi, kwaye unokugqiba ukuba kukho ukuvuza. Ukuba akukho mthombo werhasi, vala indawo yokuphuma umoya kwaye uyivuthele ngomlomo wakho. Ukongezelela, i-coil ingaphinda ihlolwe nge-multimeter.
1. Amandla kwi-valve ye-solenoid, khupha iplagi, kwaye usebenzise i-multimeter ukulinganisa ukuba kukho umbane.
2. Xa ivalve ye-solenoid ivuliwe, sondeza ucingo lwentsimbi olucekethekileyo kufutshane nekhoyili ukuze ubone ukuba akukho lufunxa na.
3. Vavanya ngokuphindaphindiweyo ivalve ye-solenoid ngokuyivula nokucima. Sebenzisa i-Allen wrench ecoleke kakhulu ukugqobhoza "umngxuma omncinci" kumbala wobhedu kwi-axis yevalve yesolenoid ukubona ukuba ingafunxwa kwaye ikhutshwe.
Iindlela zokubona umgangatho we-Pneumatic solenoid valves:
First, connect the medium to be controlled (pressurized liquid, gas < air >, ngexabiso loxinzelelo oluphakathi koluhlu loxinzelelo lwevalve ye-solenoid) kwivalve ye-solenoid, kwaye emva koko unikeze amandla kwi-coil yevalve ye-solenoid. Ukuba i-medium elawulwayo idlula kwinguqu ye-state ukusuka kwi-off okanye ukusuka kwi-off ukuya, i-valve ye-solenoid ikwimeko efanelekileyo; kungenjalo, kukho ingxaki.
Iimpazamo eziqhelekileyo ze-Pneumatic solenoid valves
1. Isiphaluka esifutshane okanye isiphaluka esivulekileyo sekhoyili
Indlela yokubona: Okokuqala, yenza umlinganiselo wayo -ucime nge-multimeter. Ukuba ixabiso loxhathiso lisondela kwiqanda okanye elingenasiphelo, libonisa ukuba icoil imfutshane-ijikelezwe okanye ivuliwe{3}}ijikelezwe. Ukuba ixabiso elilinganisiweyo lokumelana liqhelekileyo (malunga ne-ohms embalwa), akuthethi ukuba ikhoyili ikwimeko efanelekileyo. Nceda wenze olu vavanyo lokugqibela lulandelayo: Fumana isikrudrayiva esincinane kwaye usibeke kufutshane nentonga yentsimbi efakwe kwikhoyili yevalve yesolenoid. Emva koko unikeze amandla kwivalve ye-solenoid. Ukuba uziva umazibuthe, ikhoyili yevalve yesolenoid ikwimeko entle; kungenjalo, yaphukile. Isisombululo: Faka enye indawo yevalve ye-solenoid coil.
2. Kukho ingxaki ngeplagi/socket
I-Fault phenomenon: Ukuba i-valve ye-solenoid yohlobo kunye neplagi / i-socket, kunokubakho iingxaki ezifana ne-plate spring spring ye-socket okanye i-wiring kwiplagi (umzekelo, intambo yamandla idibaniswe kwintambo yomhlaba), okuthintela ukunikezelwa kwamandla kwi-coil. Kungcono ukuphuhlisa umkhwa: emva kokuba iplagi ifakwe kwi-socket, i-screw kwi-screw yokulungisa; emva kokuba ikhoyili ifakwe kwi-valve core rod, jija i-nut yokulungisa.
Ukuba iplagi ye-solenoid valve coil ixhotywe ngokukhanya kwesalathisi sombane we-LED, ngoko xa usebenzisa amandla e-DC ukuqhubela i-valve ye-solenoid, kufuneka idibaniswe ngokuchanekileyo; ngaphandle koko, ukukhanya kwesalathisi akuyi kukhanya. Ukongeza, sukutshintshisa iiplagi zamandla ngokukhanya{1}}izalathi ezikhupha amandla ediode zamanqanaba ombane ohlukeneyo. Oku kunokubangela ukuba ukukhanya-kutshise/mfutshane{4}}kujikelezise unikezelo lwamandla (tshintshela kwiplagi yomgangatho wombane osezantsi) okanye ukukhutshwa kwesibane esibuthathaka kakhulu{5}}kumbane okhuphayo (tshintshela kwiplagi yomgangatho wombane ophezulu).
Ukuba akukho kukhanya kwesalathisi samandla, i-polarity yekhoyili yevalve ye-solenoid ayifuni ukwahlula (ngokungafaniyo nokuhanjiswa kwexesha le-transistor kunye ne-DC coil voltage kunye ne-intermediate relays kunye ne-DC coil voltage kunye ne-diode / resistor leakage circuit edityaniswe ngokuhambelana nekhoyili (uninzi lwala ma-relays aphakathi yi-polarity distinction yaseJapan).
Isisombululo: Lungisa iimpazamo zeengcingo, lungisa okanye utshintshe iiplagi kunye neesokethi.
3. Umba ongundoqo weValve
I-Fault Phenomenon 1: Xa uxinzelelo oluphakathi oludlula kwi-valve ye-solenoid luqhelekile, ukucofa iqhosha le-manual elibomvu le-valve ye-solenoid ayibangeli nayiphi na impendulo (i-pressure medium ayibonisi nayiphi na i-{1}}off utshintsho), ebonisa ukuba i-valve core kufuneka ibe nephutha. Isisombululo: Jonga ukuba kukho nayiphi na imiba ngesiphakathi, njengokuba kukho ukuqokeleleka kwamanzi amaninzi kumoya oxinanisiweyo (ngamanye amaxesha isahluli se-oyile{3}}asidlali indima ebalulekileyo, ngakumbi xa uyilo lombhobho lungekho mgangathweni, kuya kubakho ukuqokeleleka kwamanzi amaninzi kumoya oxinanisiweyo odlula kwivalve ye-solenoid), kwaye nokuba kukho ukungcola okuninzi okuphakathi okudluliswayo. Emva koko susa amanzi aqokelelweyo okanye ukungcola kwivalve ye-solenoid kunye nemibhobho. Ukuba ayikasebenzi, nceda ulungise okanye ubuyisele undoqo wevalve, okanye vele ubuyisele yonke ivalve yesolenoid.
I-Fault phenomenon 2: Emva kokuhlolwa, kufunyenwe ukuba i-coil iyona yasekuqaleni kwaye ipropati yamagnetic iyinto eqhelekileyo xa i-coil inikwe amandla, kodwa i-valve ye-solenoid ayisebenzi (ngeli xesha, umsebenzi weqhosha le-manual ye-valve ye-solenoid ingaba yinto eqhelekileyo), ebonisa ukuba i-valve core iphosakele.
Isisombululo: Nceda ulungise okanye ubuyisele undoqo wevalve, okanye vele ubuyisele yonke ivalve ye-solenoid.
