Lub qhov cub microwave yog ib qho khoom siv hauv tsev neeg uas nws ua tsis tiav yuav ua rau muaj teeb meem loj vim muaj kev kub nyhiab. Yog tias koj pom tias koj lub microwave tsis sov, koj tuaj yeem sim tshawb xyuas qhov ua rau koj tus kheej. Ib qho ua tau ua ntej rau qhov no yuav yog qhov kev paub txog thiab kev txawj ntse hauv thaj tsam ntawm electronics.
Lub microwave hloov lub phaj, tab sis tsis sov
Nyob rau hauv qhov no, qhov teeb meem yuav yog qhov teeb meem ntawm ib qho hlau nplaum, lub plhaub taum, lub vojvoog hluav taws xob los yog ib lub tshuab ua khoom siv hluav taws xob.
Cov txheej txheem rau kev txhim kho yog:
- Thaum pib lub cub tawg, xyuas cov khoom ntawm qhov hluav taws xob mus rau qhov sib zog ntawm cov tshuab hluav taws xob muaj zog. Nws yog ib qho tseem ceeb heev uas yuav tau soj ntsuam cov kev tsim nyog kev tiv thaiv kev tiv thaiv tsis zoo hluav taws xob.
- Thaum muaj qhov voltage tau thov, nws tseem yuav tau xyuas qhov kev ntseeg ntawm cov neeg nyob ntawm lub siab-qhov siab. Nws muaj xws li ib tug magnetron, ib lub tshuab muaj roj-voltage, lub tshuab ua hluav taws xob muaj siab thiab ib lub voj-siab voltage.
- Yog tias cov neeg muaj kev sib raug zoo, koj yuav tsum hloov cov ntawv magnetron nrog ib tus neeg ua haujlwm. Nws kuj tseem pom zoo kom hloov cov diode siab.
Microwave pib qhuav heev li
Yog vim li cas qhov kev txhaum no kuj yuav muaj ntau:
- Tsawg voltage nyob rau hauv lub network - tsawg dua 200 volts.
- Malfunction ntawm lub timer los yog tus tswj tsev.
- Malfunction ntawm magnetron, high-voltage transformer, high-voltage diode, high-voltage fuse los yog capacitor.
- Lub tsis ua hauj lwm ntawm qhov inverter yog nyob rau hauv microwave ncu ntawm qhov inverter hom.
Kev kuaj mob nyob rau hauv qhov kev tshwm sim uas lub microwave tau ua tsis sov, yuav muaj xws li cov hauv qab no:
Kos qhov voltage hauv qhov mains. Nyob rau hauv rooj plaub nws tau poob, lub cub microwave yuav khiav lag luam nyob rau hauv hom dhau los, thaum nws yog tus cev.
Yog tias qhov voltage yog qhov qub, cov hlau nplaum raug hloov nrog ib daim txiag tshiab.
Microwave buzzes tab sis tsis sov
Nyob rau hauv ib qhov teeb meem twg cov microwave yog nrov, tab sis tsis sov, cov hauv qab no tej zaum yuav raug faulty:
- High-voltage diode . Nws kis tau tam sim no hauv ib qho kev coj, nrog lub diode thaiv nws cov zaj nyob rau hauv qhov opposite direction. Yog hais tias nws lov, koj yuav hnov ib tug neeg daig, tab sis qhov cub tsis kub. Lub diode hloov nrog lub tshiab.
- High-voltage capacitor . Nyob rau hauv cov ntaub ntawv no, yuav tsis muaj cim ntawm microwaves. Qhov daws ntawm qhov teeb meem tseem yuav hloov lub capacitor los ntawm ib lub tshiab. Ua ntej kuaj los yog hloov nws, nws yuav tsum raug tso tawm.
- Magnetron , uas yuav tsum tau hloov.
Magnetron tsis ua hauj lwm
Xws li ib qho tseem ceeb ntawm lub qhov cub microwave,
- Xyuas kom meej tias thaum lub sij hawm ua haujlwm hauv qhov cub tsis muaj khoom;
- Tsis txhob cia cov tais diav lossis lwm yam khoom hlau nkag mus rau qhov cub thaum lub sijhawm ua haujlwm.
Yog li, tom qab koj pom tias koj lub microwave tau tawg thiab tsis kub, koj tuaj yeem ua thawj tes haujlwm yog tias koj muaj kev paub txog. Yog tias tsis paub tseeb, nws xav kom koj hu rau cov kws kho tshwj xeeb.
