Pa Meyi 5, 2017, pampu ya hydrocracking nthawi zambiri idayamba p-1106 /B pampu, zoyendera zakunja za LIQUEFIED petroleum gas. Pachiyambi ndondomeko, anapeza kuti mpope chisindikizo kutayikira (kulowa kuthamanga 0.8mpa, kutulutsa kuthamanga 1.6mpa, sing'anga kutentha 40 ℃). Woyang'anira mayendedwe a Guan nthawi yomweyo adakonza antchito kuti ayimitse mpope, kutseka ma valve olowera ndi kutulutsa, ndikuchepetsa kupsinjika kwa chingwe cha nyali. Kusintha kwa nayitrogeni kunachitika. Popeza ma gaskets sanafike, msonkhanowo udakonzekera kukonza pa Meyi 6. Nthawi ya 8:00 pa May 6, hydrogenation Workshop 1 inadziwitsa msonkhano wokonza makina opangira zitsulo za kampani yomanga ndi kukonza kuti ilowe m'malo mwa chisindikizo cha P-1106 / B, ndipo malo okonzera zoyeretsera anakonza anthu asanu ndi mmodzi kuphatikizapo mtsogoleri wa gulu kuti akonze ndi kusinthidwa. 9:10, hydrogenation idapereka msonkhano usanachitike kuwunika kwachitetezo cha ntchito, mapaipi ndi zida pambuyo potseguka, chilolezo chogwira ntchito, woyang'anira malo ochitira msonkhano wa hydrogenation kuti atseke kuyang'anira pamalopo, tsegulani valavu yolowera pampu, ndi valavu yotulutsa ndi kupanikizika. kuyeza ndi ogwira ntchito yakunyumba kuti atsimikizire, chiwongolero pa valavu yachigumula popanda kutulutsa zinthu, kutulutsa kwamphamvu kwapampu kumawonetsedwa ngati "0", Ntchitoyi iyambika pambuyo pake. kutsimikizira pamalowo ndi onse awiri. Nthawi imati 9:40, pamene ogwira ntchito yosamalira anachotsa mabawuti onse a mpope, thupi la mpope linatuluka mwadzidzidzi kuchokera pa volute, ndipo wogwiritsa ntchito yomwe anali atagwira polumikizira thupi lake ndi dzanja anagunda cholumikizira chamoto ndi mkono wake wakumanzere, ndikupangitsa kuvulala kwa mkono wake wakumanzere.

2.Kusanthula chifukwa

(1) Chifukwa chachindunji: Pochotsa mpope, pali mphamvu yotsalira ya nayitrogeni mu chipolopolo cha mpope, chomwe chimapangitsa kuti thupi la mpope litulutsidwe kuchokera ku chipolopolo cha mpope, kuvulaza.

(2) Chifukwa chosalunjika: Pa Meyi 5, mtsogoleri wa shift analinganiza anthu kuti akonze mpope wa P1106/B, anatseka polowera polowera ndi mavavu otulutsira pampu, kutsitsa mphamvu ya nyaliyo, ndikusintha nayitrogeni. Pa Meyi 6, valavu yosambira yolowera pampu idatsegulidwa kuti ichepetse kupanikizika musanagwire ntchito. Pambuyo potsimikizira kuti palibe mpweya womwe unatulutsidwa, kuthamanga kwa gauge kunali zero, zomwe zinaganiza molakwika kuti panalibe sing'anga mu mpope. M'malo mwake, kukumbukira kwapampu kunali ndi mphamvu yotsalira chifukwa chosakwanira kutsegula kwa valve yosamba. Kuthamanga kwapakati ndi 4.0mpa, ngakhale kumakwaniritsa zofunikira, koma pamene kupopera kwapampu kuli kochepa, kupanikizika kotsalira chifukwa cha zotsatira za kulondola kwachitsulo sikungathe kuwonetsedwa.

3. Zochitika ndi maphunziro

(1) Ntchito iliyonse iyenera kuchitidwa moyenera kuchotsa, kudzipatula mphamvu,Lockout tagoutntchito, nthawi yomweyo kuchita ntchito yabwino kukhazikitsa ndi kutsimikizira miyeso, kuonetsetsa chitetezo ndi kulamulira ndondomeko yonse ya ntchito.

(2) Limbikitsani kasamalidwe ka chitetezo cha ntchito zoyendera ndi kukonza, kukonza luso lozindikiritsa zoopsa, ndikuchita ntchito yabwino yopewera. Kusanthula kwachitetezo chachitetezo chisanachitike kuyenera kuchitidwa musanagwire ntchito. Kuyang'anira ndi kukonza zida, makamaka potsegulira mapaipi ndi zida zotsegulira, kuyenera kuchitidwa mosamalitsa ndi kuyeretsa, kusamutsidwa, kuchepetsa kupanikizika ndi kukhetsa kuti zitsimikizire kudzipatula, kukhetsa ndi kutaya.
