I. Ikhondo lengozi

Ngomhla we-5 kaMeyi, i-2017, iyunithi ye-hydrocracking iqhele ukuqala i-p-1106 / B impompo, ukuthuthwa kwangaphandle kwangaphandle kwe-LIQUEFIED petroleum gas.Ngexesha lenkqubo yokuqala, kwafunyaniswa ukuba ukuvuza kwetywina lokumpompa (uxinzelelo lwe-inlet 0.8mpa, uxinzelelo lokuphuma 1.6mpa, ubushushu obuphakathi 40 ℃).Umlindi wokutshintsha uGuan waququzelela ngokukhawuleza abasebenzi ukuba bamise impompo, bavale iivalvu zokungena kunye nokuphuma, kunye nokunciphisa uxinzelelo kumgca wetotshi.Ukutshintshwa kwenitrogen kwenziwa.Ekubeni ii-gaskets zingazange zifike, iworkshop yayicwangcise ukwenza ulungiso nge-6 kaMeyi.Ngentsimbi yesi-8:00 ngoMeyi 6, i-hydrogenation Workshop 1 yazisa iworkshop yokulungisa indawo yokucokisa yokwakhiwa nokulungiswa kweNkampani ukuze ithathe indawo yetywina le-P-1106/B, kwaye iworkshop yokulungisa indawo yokucokisa yalungiselela abantu abathandathu kuquka nenkokeli yeqela ukulungiselela ukulungiswa nokutshintshwa.9:10, i-hydrogenation ikhuphe iworkshop phambi kohlahlelo lokhuseleko lomsebenzi, umbhobho kunye nezixhobo emva kokuvula, imvume yokusebenza, iworkshop hydrogenation shift supervisor ukuvala uhlolo olukwisiza, vula ivalve yempompo yesikhokelo sokuphuma kwamanzi, kunye nevalve yokukhupha noxinzelelo. igauge kunye nabasebenzi basekhaya ukuze kuqinisekiswe, isikhokelo kwivalve yokukhukula ngaphandle kokukhutshwa kwezinto eziphathekayo, uxinzelelo lwe-pump outlet gauge yoxinzelelo luboniswa njenge "0", Umsebenzi uya kuqaliswa emva kokuqinisekiswa kwesayithi ngamaqela omabini.Ngentsimbi ye-9:40, xa abasebenzi bolondolozo besusa zonke iibholithi zokuvala impompo, umzimba wempompo ngequbuliso wabaleka waphuma kwi-volute, kwaye umsebenzi owayebambe impompo edibanisa umzimba ngesandla wabetha udibaniso lwemoto ngengalo yakhe yasekhohlo, ebangela ukuba umntu obambe impompo edityaniswe yimpompo edibanisa iibholiti zempompo ngengalo yakhe yasekhohlo. ukwenzakala kwingalo yakhe yasekhohlo.

2.Uhlalutyo lwesizathu

(1) Isizathu esithe ngqo: Kwinkqubo yokususa impompo, kukho uxinzelelo lwe-nitrogen olushiyekileyo kwigobolondo yempompo, ebangela ukuba umzimba wempompo ukhutshwe kwi-shell shell, kubangela ukulimala.

(2) Isizathu esingathanga ngqo: NgoMeyi 5, inkokeli yeshifti yaququzelela abasebenzi ukuba basebenze impompo ye-P1106/B, yavala indawo yokupompoza yokungena kunye neevalvu zokuphuma, yakhulula uxinzelelo kwitotshi, yaza yathatha indawo yenitrogen.Ngomhla we-6 kaMeyi, i-valve ye-pump inlet yeshawari yavulwa ukukhulula uxinzelelo ngaphambi kokusebenza.Emva kokuqinisekisa ukuba akukho gesi ekhutshweyo, uxinzelelo lwe-gauge lwaluyi-zero, eyayicinga ngephutha ukuba akukho nto iphakathi kwimpompo.Ngapha koko, inkumbulo yempompo yayinoxinzelelo olushiyekileyo ngenxa yokungonelanga kwendawo yokuvula yevalve yeshawa.Uluhlu lwe-pressure gauge yi-4.0mpa, nangona ihlangabezana neemfuno, kodwa xa uxinzelelo lwempompo luphantsi, uxinzelelo olushiyekileyo ngenxa yempembelelo yokulinganisa ukuchaneka kwengcinezelo ayikwazi ukuboniswa.

3. Amava kunye nezifundo

(1) Nawuphi na umsebenzi kufuneka wenziwe ngokufanelekileyo inkqubo yokulahlwa, ukwahlula amandla,Ukutshixa tagoutumsebenzi, ngexesha elifanayo wenze umsebenzi omhle wokuphunyezwa kunye nokuqinisekiswa kwamanyathelo, ukuqinisekisa ukhuseleko kunye nokulawulwa kwayo yonke inkqubo yokusebenza.

(2) Ukuqinisa ulawulo lokhuseleko lwemisebenzi yokuhlola kunye nokugcinwa, ukuphucula amandla okuchonga umngcipheko, kunye nokwenza umsebenzi omhle wokuthintela.Uhlalutyo lokhuseleko lwangaphambi komsebenzi kufuneka lwenziwe ngaphambi kokusebenza.Ukuhlolwa kwezixhobo kunye nokugcinwa, ngokukodwa ukusebenza kwemibhobho kunye nokusebenza kokuvulwa kwezixhobo, kufuneka kwenziwe ngokucokisekileyo ngokucoca, ukufuduswa, ukunciphisa uxinzelelo kunye nokukhupha ukuze kuqinisekiswe ukwahlula okusebenzayo, ukukhupha kunye nokukhupha.
