Multimeter Test rau Solenoid Pull-in & Tuav Coil Resistance
Kev ua haujlwm tam sim no ntawm lub tshuab hluav taws xob pib yog siab thiab qhov ceev yog siab. Txhawm rau kom ntseeg tau tias kev ua haujlwm ntawm lub cev muaj zog, lub tsheb pib yuav tsum tau siv kom raug; Vim qee qhov kev ua haujlwm tsis tsim nyog, malfunctions yuav tshwm sim, xws li:
Thaum pib lub cev ua haujlwm tsis zoo, lub tshuab hluav taws xob pib feem ntau yog qhov cuam tshuam rau qhov tsis ua haujlwm. Hauv kev pib ua haujlwm, vim qhov nyuaj ntawm cov khoom siv hauv lub cev thiab kev ntseeg siab ntawm kev tswj hwm, cov kev xav tau ntawm lub cev muaj zog yog qhov tseem ceeb heev. Yog li ntawd, pib lub cev muaj zog ua lub luag haujlwm tseem ceeb hauv kev pib. Thaum txheeb xyuas qhov tsis ua haujlwm ntawm qhov pib, kev saib xyuas txaus yuav tsum tau them rau kev txheeb xyuas ntawm lub cev muaj zog pib. Hauv qab no yog ib qho ntawm cov ntsiab lus - kuaj xyuas qhov ua haujlwm ntawm cov hluav taws xob hloov hluav taws xob ntawm lub tsheb. Cov kauj ruam tseem ceeb tuaj yeem ua raws li:
1. Txheeb xyuas qhov tsis kam ntawm electromagnetic hloov attraction coil
Xaiv lub multimeter nyob rau hauv lub ohm ntau yam, thiab txuas ob lub probes mus rau lub davhlau ya nyob twg 2 thiab terminal 3 ntawm lub electromagnetic hloov. Tus nqi tsis zoo yog feem ntau 0.5 ~ 1.0 Ω. Yog hais tias tus nqi kuj yog infinite, nws qhia tau hais tias lub attraction coil yog disconnected. Thaum lub tshuab hluav taws xob tig mus rau qhov chaw pib, qhov hloov hluav taws xob tsis muaj qhov ua haujlwm; Yog hais tias tus nqi kuj tsawg dhau, nws qhia tau hais tias muaj luv luv Circuit Court ntawm lub lem ntawm lub attraction coil. Thaum lub tshuab hluav taws xob hloov pauv mus rau qhov chaw pib, lub tshuab hluav taws xob hloov hluav taws xob muaj qhov ua haujlwm tsis muaj zog, emitting lub suab tsis muaj zog "nias, nias, nyem" thiab lub iav tsav tsheb tsis muaj kev ua haujlwm.
2. Txheeb xyuas qhov tsis kam ntawm electromagnetic hloov tuav kauj
Xaiv lub multimeter nyob rau hauv lub ohm ntau yam, thiab txuas ob probes mus rau peb lub terminals ntawm lub electromagnetic hloov thiab lub electromagnetic hloov vaj tse nyob. Tus nqi kuj feem ntau yog 1.0 ~ 1.5 Ω. Yog hais tias tus nqi kuj yog infinite, nws qhia tau hais tias lub kauj yog khaws cia qhib Circuit Court; Yog tias tus nqi tiv thaiv tsawg dhau, nws qhia tau hais tias lub kauj voj voog luv luv. Txawm hais tias ua kom lub coil qhib los yog lub voj voog luv luv, lub tshuab hluav taws xob hloov hluav taws xob yuav ua rau "nias, nyem, nyem" suab, thiab lub iav tsav yuav tsis txav mus. Qhov sib txawv tsuas yog tias qhov zaus ntawm lub suab tsim los ntawm kev tig mus tig luv luv yog qis dua li tom qab lub voj voog tawg.
