Yuav ua li cas txheeb xyuas lub thermal fuse nrog multimeter
Txheem
Thermal fuses feem ntau tshuab vim muaj zog surges thiab qee zaum vim clogging. Koj tsis tuaj yeem saib ntawm lub fuse thiab pom tias nws puas tau tawg, koj yuav tsum ua qhov kev sim txuas ntxiv.
Kev tshawb xyuas txuas ntxiv txiav txim siab qhov muaj qhov txuas hluav taws xob txuas ntxiv mus. Yog tias lub thermal fuse muaj kev ncaj ncees, ces nws ua haujlwm, thiab yog tias tsis yog, ces nws yog faulty thiab yuav tsum tau hloov.
Kab lus no yuav piav qhia ob peb kauj ruam yooj yim los xyuas seb lub fuse puas muaj qhov txuas txuas ntxiv lossis tsis yog. Txhawm rau ua qhov no, koj yuav xav tau multimeter, nyiam dua digital multimeter.
Rau kev sim, koj yuav tsum ua raws li cov kauj ruam no:
1. Nrhiav thiab tshem tawm lub fuse ntawm koj lub cuab yeej,
2. Qhib lub thermal fuse yam tsis muaj kev puas tsuaj lossis ua rau koj tus kheej raug mob, thiab thaum kawg
3. Teem lub multimeter mus rau hom kom raug los kuaj kom txuas ntxiv mus.
Cov Cuab Yeej Yuav Tau Ua
Koj yuav xav tau cov cuab yeej hauv qab no los ntsuas fuse txuas ntxiv:
- Functional digital lossis analog multimeter
- Thermal fuse los ntawm cov khoom siv tsis raug
- Txuas xov hlau los yog sensors
- Cov khoom siv hluav taws xob
- Screwdrivers ntawm ntau qhov sib txawv
Yuav ua li cas txheeb xyuas lub fuse nrog multimeter
Ua raws li cov kauj ruam hauv qab no kom nkag siab tias koj yuav tsum tau ua dab tsi kom paub seb koj lub fuse puas nyob rau hauv qhov zoo.
- Qhov chaw thiab tshem tawm cov thermal fuse: Thermal fuses muaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg. Lawv txhua tus muaj tib lub luag haujlwm sab hauv uas txhais tau tias lawv cov haujlwm ua haujlwm. Piv txwv li, yog tias koj siv lub tshuab ziab khaub ncaws, koj yuav pib tshem tag nrho cov ntsia hlau thiab nrhiav lub thermal fuse. Tom qab ntawd tshem cov xov hlau thiab tshem tawm cov fuse. Cov ntawv cim fuse pab peb kom paub tseeb tias cov khoom siv tsis txuas nrog lub zog hluav taws xob. Qhov no pab peb kom tsis txhob muaj hluav taws xob poob. Feem ntau cov fuses ruaj ntseg ruaj ntseg hauv vaj huam sib luag nkag. Lawv raug ntsia tom qab cov zaub lossis vaj huam sib luag tswj (piv txwv li, hauv qhov cub microwave lossis tshuab ntxhua khaub ncaws). Nyob rau hauv lub tub yees, thermal fuses muaj nyob rau hauv lub freezer. Nws yog tom qab lub evaporator npog vim lub rhaub. (1)
- Yuav ua li cas qhib lub thermal fuse yam tsis muaj kev puas tsuaj los yog ua rau koj tus kheej raug mob: Txhawm rau qhib lub fuse, tshem tawm cov xov hlau los ntawm cov terminals. Tom qab ntawd siv lub hau ntswj kom tshem tawm cov ntsia hlau tuav lub thermal fuse nyob rau hauv qhov chaw.
- Yuav Ua Li Cas Npaj Ib Lub Multimeter rau Kev Ntsuas Txuas NtxivA: Ua ntej koj tuaj yeem txiav txim siab seb puas yuav hloov lub fuse qub lossis tsis tau, koj yuav tsum ua qhov kev xeem txuas ntxiv. Koj yuav xav tau ib tug multimeter rau txoj haujlwm no. Qee zaum fuse terminals tau txhaws. Yog li ntawd, koj yuav tsum tau unclog lub blockage los ntawm tshem tawm blockages los yog av. Tom qab ntawd maj mam rub lawv nrog cov khoom siv hlau ua ntej ua qhov kev sim txuas ntxiv. (2)
Txhawm rau qhib lub multimeter, tig lub xov tooj mus rau tus nqi qis tshaj plaws hauv ohms. Tom qab ntawd, calibrate cov meters los ntawm kev txuas cov sensors ua ke. Teem lub koob rau xoom (rau ib qho analog multimeter). Rau ib tug digital multimeter, tig lub dial mus rau qhov tsawg kawg nkaus kuj tus nqi. Tom qab ntawd siv ib qho kev sojntsuam los kov ib qho ntawm qhov ntsuas qhov ntsuas thiab lwm qhov kev sojntsuam txhawm rau kov lwm lub davhlau ya nyob twg.
Yog tias qhov kev nyeem ntawv yog xoom ohms, lub fuse muaj kev ncaj ncees. Yog tias txhais tes tsis txav (rau analog) lossis yog tias cov zaub tsis hloov pauv loj (rau digital), ces tsis muaj kev txuas ntxiv. Tsis muaj kev txuas ntxiv txhais tau tias lub fuse tau tawg thiab yuav tsum tau hloov.
Hloov lub fuse tsis raug thiab cov lus qhia txog kev tu
Txhawm rau hloov cov thermal fuse, thim rov qab cov txheej txheem tshem tawm raws li saum toj no. Txhawm rau txo qhov kev pheej hmoo ntawm tshuab fuses, siv cov tswj hluav taws xob kom ncua lub zog lossis qhov hluav taws xob. Txhawm rau txo qhov txhaws, nws yog qhov yuav tsum tau kaw lub fuse thiab sau cov qhov hauv lub cuab yeej. Thaum kawg, siv lub fuse mus tas li.
Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
