Kusanthula kwa ngozi za fakitale yamagetsi yamagetsi
Dipatimenti yoyang'anira zida zamakina otenthetsera magetsi inakonza dongosolo lokonza mkati mwa makina oyeretsera malasha nambala 1, pambuyo poti yavomerezedwa kuti igwiritsidwe ntchito.

Zhang Yanqiu, munthu woyang'anira gulu logwira ntchito yokonza makina a C mill, ndi woyang'anira malo analowa mu makina a C mill kuti akayang'anire, ndipo anapeza kuti chipolopolo cha C mill centering chinali cholumikizidwa. Anaganiza zothetsa vuto la kulowetsa makina mu hot primary air duct ndi sealing gland packing fault ya baffle shaft komanso kusintha kwa mphamvu ya mpweya wotentha woyambira ntchito.

Li Deyu, woyang'anira, monga munthu wamba woyang'anira malo okonzera makina a C coal mill, adagawa ntchito zokonzera makinawo m'kalasi yopanga ufa, ndipo adatumiza Wang Hongliang ndi Tan Zhe kuti akagwire nawo ntchito yokonza makina ophikira mpweya wolowera mu C coal mill.

Masana, Li Deyu adachita msonkhano wa kalasi ndipo adakonza ntchito masana: Katswiri wa kalasi yophwanyidwa adalumikizana ndi ogwira ntchito ku Dipatimenti Yoyang'anira Kupanga Mphamvu ndipo adakonza Li Jun kuti achotse mbale ya baffle ya C coal mill yotenthetsera polowera kamodzi. Wokonza kalasi yopanga ufa amatsuka thonje lotenthetsera kutentha pamwamba pa duct yoyamba ya mpweya ndikukonza mbale ya baffle ndikusintha duct yoyamba ya mpweya; Wang Zijun, wokonza kalasi yopanga ufa, ndiye woyang'anira ntchito yochepa. Li Deyu amavomereza malo otenthetsera mpweya woyamba.

Li Jun anafika pamalo okonzera mphero ya malasha ya C, panthawiyi, nsanja yomanga nsanja ya mamita 6.9 yakhazikitsidwa, Li Deyu, Wang Hongliang, Tan Zhe akulowa mumphero ya malasha kuti agwire ntchito, Wang Zijun akuwunikira njira ya mpweya wotentha.

Li Jun anatsegula chitseko cha kabati yowongolera pa kabati yowongolera yapafupi ndi screwdriver pa nsanja ya mamita 6.9 kuti asinthe switch ya "far control/near control" kukhala "near control", ndipo anakanikiza valavu ya solenoid kuti ayambitse switch. Panalibe reaction pambuyo pa kukanikiza koyamba, ndipo panalibe reaction pambuyo pa kukanikiza kwachiwiri.

Li Jun anafuwula kwa wokonza pa payipi yoyamba ya mpweya wotentha pa nsanja ya mamita 6.9, akufunsa ngati chowongolera chinasuntha? Wokonzayo anakankha chowongolera cha baffle link ndi phazi lake ndikugwedeza dzanja lake kuti asonyeze kuti sichinasunthe.

Li Jun anatsegulanso valavu yamanja ya chitseko cha mpweya wochokera ku C coal mill inlet heating primary air insert plate, yomwe ili ndi chizindikiro chochenjeza kuti "Palibe ntchito ndi anthu". Panthawiyi, chitseko cha pulagi ya mpweya wotentha chimatsegulidwa, mpweya wotentha wa 309℃ umathiridwa mu duct ya mpweya wotentha wa C coal mill yokhala ndi mphamvu ya 6kPa, Li Deyu, Wang Hongliang, Tan Zhe akugwira ntchito pansi pa chitseko cha C coal mill.

Ogwira ntchito yopulumutsa anthu analowa pakhomo la chigayo cha malasha nambala 1 cha boiler C kuti atenthetse mpweya woyambira, kupulumutsa anthu omwe anagwidwa. Koma onse anatsimikizika kuti afa.

Chifukwa chachangu

Njira yokonza, wokonza Li Jun akuphwanya kwambiri ntchitoyo. Alibe zida zomwe zili m'mikhalidwe yofanana, yang'anani dzina la chipangizocho, kuti mutsegule chitseko cha pulagi ya solenoid valavu ya mpweya ndipo palibe "opareshoni ya wina wogwira ntchito" chikwangwani cha valavu ya mpweya pamanja, cholowera choyambirira cha mphero ya malasha chimalola mlengalenga wotentha mu chitseko chotsekedwa cha C chosuntha chotseguka, kutentha ndi 309 ℃, kuthamanga ndi 6 kpa cholowera cha mphero ya malasha chimalola mpweya kutentha mkati mwa duct, zomwe zimapangitsa ngozi kuchitika.
