Cov laj thawj tseem ceeb ntawm Relay Chattering
Hluav taws xob tawm tswv yim thiab suab nrov
Relay chattering tuaj yeem tshwm sim thaum hluav taws xob tawm tswv yim lossis suab nrov nkag rau hauv koj lub cev. Cov tshuab loj xws li motors tuaj yeem xa cov teeb liab rov qab los ntawm cov xov hlau. Cov teeb liab no tuaj yeem cuam tshuam cov relay thiab ua rau nws qhib thiab kaw nrawm. Cov xaim ntev lossis cov av tsis zoo tuaj yeem ua rau qhov teeb meem no tsis zoo. Cov suab nrov hluav taws xob tuaj yeem tuaj yeem los ntawm lwm lub tshuab, xov tooj cua, lossis txawm xob laim. Koj yuav tsum nrhiav cov xov hlau xoob thiab xyuas tias txhua qhov kev sib txuas yog nruj. Kev siv cov kab thaiv kev tiv thaiv thiab cov av zoo tuaj yeem pab txo qis suab nrov. Qee zaum, muab lub capacitor me me hla lub relay coil tuaj yeem thaiv cov cim no.
Tswv yim:Sim ua kom cov xov hlau luv luv thiab deb ntawm cov tshuab tsis muaj suab nrov kom tsis txhob tawm tswv yim hluav taws xob.
Mechanical Wear thiab Vibration
Mechanical hnav yog lub ntsiab yog vim li cas rau relay chattering, tshwj xeeb tshaj yog yog hais tias koj siv relays ntau. Txhua lub sij hawm relay switches, cov neeg muaj peev xwm thaws thiab ua sparks. Thaum lub sij hawm, qhov no bouncing hnav tawm cov neeg sib cuag sai dua. Tej zaum koj yuav pom cov qhov me me los yog cov pob zeb yaj ntawm cov neeg sib cuag, uas txhais tau hais tias lub relay yuav tsis ua haujlwm zoo. Lub suab nrov los ntawm kev sib tiv tauj tuaj yeem txav mus los ntawm qhov system thiab ua rau muaj teeb meem ntau dua.
Sparks los ntawm bouncing hu ua lub relay tawg sai.
Cov neeg hnav khaub ncaws tuaj yeem ua ke los yog tau qhov, yog li koj yuav tsum tau hloov lawv ntau zaus.
Lub suab nrov los ntawm kev sib cuag tuaj yeem txav mus los hauv av thiab ua mob rau koj lub cev.
Kev vibration los ntawm lwm lub tshuab tuaj yeem co lub relay thiab ua rau cov neeg sib cuag thaum lawv yuav tsum tsis txhob. Yog tias koj muab lub relay tso rau ntawm qhov chaw tshee, nws yuav hnav sai dua.
Voltage thiab fais fab teeb meem
Relay chattering feem ntau tshwm sim thaum qhov hluav taws xob lossis lub zog tsis ruaj khov. Yog tias qhov hluav taws xob poob qis dhau lawm, lub relay coil tsis tuaj yeem kaw cov neeg sib cuag. Lub relay yuav pib qhib thiab kaw sai sai. Kev hloov pauv ntawm lub zog tam sim no tuaj yeem ua rau muaj teeb meem no. Koj yuav tsum xyuas koj lub hwj chim nrog ib lub 'meter' kom paub tseeb tias nws nyob hauv qhov zoo. Cov roj teeb qub lossis tsis muaj zog, cov khoom siv hluav taws xob tsis zoo, lossis cov khoom siv hluav taws xob uas muaj ntau dhau tuaj yeem ua rau muaj teeb meem voltage.
Ib puag ncig kuj tseem ceeb. Cov av noo siab tuaj yeem ua rau cov neeg sib txuas lus tsis zoo, uas ua rau lawv ua haujlwm tsis zoo. Thaum tshav kub kub tuaj yeem ua rau cov khoom hauv lub relay loj dua. Qhov no ua rau cov neeg sib cuag nyuaj rau kaw thiab tsim kom muaj cua sov ntau dua, uas ua rau qhov teeb meem loj dua.
