Umonakalo woomatshini
I. Indlela eyaqala ngayo ingozi

Ngomhla wesi-5 kuCanzibe ngo-2017, iyunithi yokucima amanzi yayidla ngokuqala ipompo ye-p-1106 /B, ukuthuthwa ngaphandle kwegesi yepetroleum ye-LIQUEFIED ngaphandle okwethutyana. Ngexesha lenkqubo yokuqala, kwafunyaniswa ukuba ukuvuza kwetywina lepompo (uxinzelelo lokungena yi-0.8mpa, uxinzelelo lokuphuma yi-1.6mpa, ubushushu obuphakathi yi-40℃). I-shift monitor uGuan yalungiselela ngoko nangoko abasebenzi ukuba bamise ipompo, bavale iivalvu zokungena kunye nezokuphuma, baze banciphise uxinzelelo kumgca wetotshi. Kwenziwe ukutshintshwa kwe-nitrogen. Ekubeni iigaskets zingafikanga, i-workshop yayiceba ukwenza ulondolozo ngoMeyi 6. Ngentsimbi yesi-8:00 ngoMeyi 6, i-hydrogenation Workshop 1 yazisa i-workshop yokugcinwa kwe-refinery yeNkampani yokwakha nokulungisa ukuba ithathe indawo yetywina ye-P-1106 /B, kwaye i-workshop yokugcinwa kwe-refinery yalungiselela abantu abathandathu kuquka nenkokeli yeqela lokugcinwa kunye nokutshintshwa. 9:10, i-hydrogenation ikhuphe i-workshop ngaphambi kohlalutyo lokhuseleko lomsebenzi, imibhobho kunye nezixhobo emva kokuvulwa, imvume yokusebenza, umphathi we-workshop hydrogenation shift ukuvala uhlolo kwindawo, avule i-pump inlet guide flood valve, kunye ne-discharge valve kunye ne-pressure gauge kunye nabasebenzi besikolo ukuze baqinisekise, isikhokelo kwi-flood valve ngaphandle kokukhupha izinto, i-pump outlet pressure gauge iboniswa njengo-“0”. Umsebenzi uza kuqaliswa emva kokuqinisekiswa kwendawo ngamaqela omabini. Ngo-9:40, xa abasebenzi bolondolozo besusa zonke iibholithi ze-pump cover, umzimba we-pump ngequbuliso waphuma kwi-volute, kwaye umqhubi owayebambe i-pump body coupling ngesandla wabetha i-motor semi-coupling ngengalo yakhe yasekhohlo, nto leyo eyabangela ukwenzakala kwingalo yakhe yasekhohlo.

2. Uhlalutyo lwesizathu

(1) Unobangela othe ngqo: Kwinkqubo yokususa ipompo, kukho uxinzelelo olushiyekileyo lwe-nitrogen kwigobolondo lepompo, nto leyo ebangela ukuba umzimba wepompo utyhalelwe ngaphandle kwigobolondo lepompo, nto leyo ebangela ukwenzakala.

(2) Isizathu esingangqalanga: Ngomhla wesi-5 kuCanzibe, inkokheli yeshifti yaququzelela abasebenzi ukuba basebenze ipompo ye-P1106/B, bavala iivalvu zokungena kunye nezokuphuma kwepompo, bakhulula uxinzelelo oluya kwitotshi, baza batshintsha i-nitrogen. Ngomhla wesi-6 kuCanzibe, ivalvu yeshawa yokungena kwepompo yavulwa ukuze kuncitshiswe uxinzelelo ngaphambi kokuba isebenze. Emva kokuqinisekisa ukuba akukho gesi ikhutshiweyo, uxinzelelo lwegeyiji lwaluyi-zero, nto leyo eyayicinga ngempazamo ukuba akukho medium kwipompo. Enyanisweni, imemori yepompo yayinoxinzelelo olushiyekileyo ngenxa yendawo yokuvula enganeleyo yevalvu yeshawa. Uluhlu lwegeyiji yoxinzelelo yi-4.0mpa, nangona ihlangabezana neemfuno, kodwa xa uxinzelelo lwepompo luphantsi, uxinzelelo olushiyekileyo ngenxa yempembelelo yokuchaneka kwegeyiji yoxinzelelo alunakuboniswa.

3. Amava kunye nezifundo

(1) Naluphi na umsebenzi kufuneka wenziwe ngendlela eyiyo, ukuchithwa kwamandla,Ithegi yokutshixa ngaphandleumsebenzi, kwangaxeshanye benze umsebenzi olungileyo wokuphumeza nokuqinisekisa amanyathelo, ukuqinisekisa ukhuseleko nolawulo lwenkqubo yonke yokusebenza.

(2) Ukuqinisa ulawulo lokhuseleko lwemisebenzi yokuhlola nokugcina, ukuphucula amandla okuchonga umngcipheko, kunye nokwenza umsebenzi olungileyo wokuthintela. Uhlalutyo lokhuseleko lwangaphambi komsebenzi kufuneka lwenziwe ngaphambi kokusebenza. Ukuhlolwa nokugcinwa kwezixhobo, ingakumbi imisebenzi yokuvula imibhobho kunye nezixhobo, kufuneka kwenziwe ngokucoca, ukuhambisa, ukunciphisa uxinzelelo kunye nokukhupha izinto ukuze kuqinisekiswe ukuba ziyahlukaniswa, zikhutshwa kwaye zikhutshwa.
