Ukulimala komshini
I. Indlela yengozi

Ngomhla zi-5 kuNhlaba wezi-2017, iyunithi ye-hydrocracking ngokuvamile iqale iphampu ye-p-1106 /B, ukuthuthwa kwesikhashana kwangaphandle kwe-LIQUEFIED petroleum gas.Ngesikhathi senqubo yokuqala, kwatholakala ukuthi ukuvuza kwe-pump seal (ingcindezi ye-inlet 0.8mpa, ingcindezi yokukhipha i-1.6mpa, izinga lokushisa eliphakathi ngu-40 ℃).I-shift monitor u-Guan wahlela ngokushesha abasebenzi ukuthi bamise iphampu, bavale ama-valve okungenisa kanye nokuphumayo, futhi bakhulule ingcindezi entanjeni yethoshi.Ukushintshwa kwe-nitrogen kwenziwa.Njengoba ama-gaskets engafikanga, ishabhu yahlela ukwenza ukulungiswa ngoMeyi 6.Ngo-8:00 ngoMeyi 6, i-hydrogenation Workshop 1 yazisa ishabhu yokulungisa indawo yokuhluza yeNkampani yokwakha nokulungisa ukuze ithathe indawo yophawu lwe-P-1106/B, futhi indawo yokusebenzela yokulungisa indawo yokuhluzwa yahlela abantu abayisithupha okuhlanganisa nomholi weqembu ukuze banakekele futhi bashintshe.9:10, i-hydrogenation ikhiphe ishabhu ngaphambi kokuhlaziywa kokuphepha komsebenzi, ipayipi kanye nemishini ngemva kokuvula, imvume yokusebenza, ishabhu lokusebenzela i-hydrogenation shift supervisor ukuze kuvalwe ukuhlolwa endaweni, ukuvula i-valve yomhlahlandlela wokungena kwephampu kazamcolo, kanye nevalvu yokukhipha nokucindezela. geji nabasebenzi bomsebenzi wesikole wasekhaya ukuze kuqinisekiswe, umhlahlandlela ku-valve kazamcolo ngaphandle kokukhipha impahla, ukucindezela kwegeji ye-pump outlet kuboniswa njengokuthi “0″, Umsebenzi uzoqala ngemva kokuqinisekiswa kwendawo yizo zombili izinhlangothi.Ngo-9:40, lapho izisebenzi ezilungisayo zikhipha wonke amabhawodi ekhava ephampu, umzimba wepompo wavele wagijima waphuma kuvolute, futhi u-opharetha owayebambe iphampu ehlanganisa umzimba ngesandla washaya ingxenye yephampu ngengalo yakhe yangakwesokunxele, okubangele ukuthi. ukulimala engalweni yakhe yangakwesobunxele.

2.Ukuhlaziya imbangela

(1) Isizathu esiqondile: Enqubweni yokukhipha iphampu, kukhona ukucindezela kwe-nitrogen eyinsalela egobolondweni lepompo, okubangela ukuthi umzimba wepompo uphushwe ngaphandle kwegobolondo lepompo, okubangela ukulimala.

(2) Isizathu esingaqondile: NgoMeyi 5, umholi weshifu wahlela izisebenzi ukuthi zicubungule iphampu ye-P1106/B, wavala ama-valve okungenisa iphampu nama-outlet valve, wehlisa ukucindezela kwethoshi, futhi washintsha i-nitrogen.Ngomhlaka-6 Meyi, i-valve ye-pump inlet shower yavulwa ukuze ikhulule ingcindezi ngaphambi kokusebenza.Ngemva kokuqinisekisa ukuthi ayikho igesi ekhishiwe, ukucindezela kwegeji kwakunguziro, okwacabanga ngephutha ukuthi kwakungekho medium empompini.Eqinisweni, inkumbulo yephampu yayinengcindezi eyinsalela ngenxa yokunganele kokuvula indawo ye-valve yokugeza.Ibanga lokulinganisa ingcindezi liyi-4.0mpa, nakuba lihlangabezana nezidingo, kodwa lapho ingcindezi yepompo iphansi, ingcindezi esele ngenxa yomthelela wokunemba kwegeji yengcindezi ayikwazi ukuboniswa.

3. Okuhlangenwe nakho nezifundo

(1) Noma yimuphi umsebenzi kumele kwenziwe ngendlela efanele inqubo yokulahlwa, ukuhlukaniswa kwamandla,I-lockout tagoutumsebenzi, ngesikhathi esifanayo wenze umsebenzi omuhle wokuqalisa nokuqinisekisa izinyathelo, ukuqinisekisa ukuphepha nokulawula yonke inqubo yokusebenza.

(2) Ukuqinisa ukuphathwa kokuphepha kwemisebenzi yokuhlola nokunakekela, ukuthuthukisa ikhono lokuhlonza ingozi, nokwenza umsebenzi omuhle wokuvimbela.Ukuhlaziywa kokuphepha kwangaphambi komsebenzi kufanele kwenziwe ngaphambi kokusebenza.Ukuhlolwa nokugcinwa kwemishini, ikakhulukazi imisebenzi yokuvula amapayipi kanye nemishini, kumele kwenziwe ngokucophelela ngokuhlanzwa, ukususwa kwendawo, ukukhulula ingcindezi kanye nokukhipha ukuze kuqinisekiswe ukuhlukaniswa okusebenzayo, ukuthulula nokukhipha.
