1. Kev qhib thiab kaw: Thaum ua haujlwm ntawm lub tshuab nqus tsev vacuum, thawj kauj ruam yog ua haujlwm qhib thiab kaw. Qhov no feem ntau yog ua tiav los ntawm lub cev muaj zog lossis phau ntawv ua haujlwm, feem ntau yog siv dual braking, tsav lub cev muaj zog thiab lwm yam txhais tau tias kom muaj kev nyab xeeb thiab kev ntseeg tau ntawm kev qhib thiab kaw haujlwm.
2. Kev siv lub tshuab nqus tsev filling: Lub tshuab nqus tsev vacuum ua haujlwm nyob rau hauv lub tshuab nqus tsev, yog li yuav tsum tau ua haujlwm ntawm lub tshuab nqus tsev. Thaum ua haujlwm, nws yog ib qho tsim nyog yuav tsum tau ua ntej tswj lub xeev ntawm lub tshuab, thiab tom qab ntawd manually sau lub tshuab nqus tsev. Microcomputer hluav taws xob tswj tuaj yeem siv los ua kom tiav cov haujlwm tshwj xeeb ntawm kev tuav lub tshuab nqus tsev.
3. Kev tshawb nrhiav tsis siv neeg: Thaum lub tshuab nqus tsev vacuum breaker ua haujlwm, kev kuaj xyuas tsis siv neeg yuav tsum tau kuaj xyuas qhov tsis raug thiab lwm yam teeb meem. Qhov no yog ib qho tseem ceeb txhais tau tias kom muaj kev ruaj ntseg ntawm lub hwj chim system. Thaum kuaj pom, kev saib xyuas yuav tsum tau them rau seb puas muaj qhov tsis raug xws li qhib circuits thiab grounding, thiab kev ua haujlwm tswb yuav tsum tau ua.
4. Tswb tuav: Thaum lub tshuab nqus tsev vacuum breaker ntes tau ib qho txhaum, nws yuav tsum tau muab lub tswb tam sim ntawd. Feem ntau, lub suab thiab lub teeb ceeb toom, lub tswb ceeb toom, thiab lwm txoj kev siv. Nyob rau tib lub sijhawm, kev tswj xyuas qhov tsis raug yog qhov tsim nyog los xyuas kom meej tias cov khoom siv ua haujlwm zoo li qub.
