Musi wa5 Chivabvu, 2017, unit ye ​​hydrocracking yaiwanzotanga pombi ye p-1106 /B, ichifambisa gasi remafuta re LIQUEFIED kunze kwenguva pfupi. Munguva yekutanga, zvakaonekwa kuti pombi yaibuda (inlet pressure 0.8mpa, outlet pressure 1.6mpa, pakati nepakati 40℃). Guan, shift monitor, akabva aronga vashandi kuti vamise pombi, vavhare mavharuvhu e inlet nee outlet, uye vabvise kumanikidzwa kutambo ye torch. Kutsiva nitrogen kwakaitwa. Sezvo magasket asina kusvika, workshop yakaronga kuita kugadzirisa musi wa6 Chivabvu. Na8:00 musi wa6 Chivabvu, hydrogenation Workshop 1 yakazivisa workshop yekuchengetedza refinery yeKambani yekuvaka nekugadzirisa kuti itsive P-1106 /B seal, uye workshop yekuchengetedza refinery yakaronga vanhu vatanhatu kusanganisira mutungamiri wechikwata chekugadzirisa nekutsiva. 9:10, hydrogenation yakaburitsa workshop isati yaongororwa kuchengetedzeka kwebasa, mapaipi nemidziyo mushure mekuvhurwa, mvumo yebasa, mutariri weshanduko yehydrogenation yeworkshop kuti avhare ongororo panzvimbo, avhure pombi inlet guide flood valve, uye discharge valve nepressure gauge nevashandi vebasa repamba kuti vasimbise, gwara pavharuvhu yeflood isina zvinhu zvinoburitsa, pombi outlet pressure gauge pressure inoratidzwa se "0", Basa racho richatanga mushure mekusimbiswa panzvimbo nemapoka ese ari maviri. Na9:40, vashandi vekugadzirisa pavakabvisa mabhoti ese epombi, pombi body yakangoerekana yabuda muvolute, uye mushandi akanga akabata pombi body coupling neruoko akarova mota neruoko rwake rweruboshwe, zvichikonzera kukuvara kuruoko rwake rweruboshwe.

2. Kuongorora chikonzero

(1) Chikonzero chakananga: Pakubvisa pombi, pane nitrogen inosara muganda repombi, izvo zvinoita kuti muviri wepombi usundirwe kunze kubva muganda repombi, zvichikonzera kukuvara.

(2) Chikonzero chisina kunanga: Musi wa5 Chivabvu, mutungamiri weshift akaronga vashandi kuti vagadzire pombi yeP1106/B, akavhara mavharuvhu ekupinda neanobuda papombi, akabvisa kumanikidzwa kuenda kumwenje, uye akatsiva nitrogen. Musi wa6 Chivabvu, vharuvhu yekugeza inopinza pombi yakavhurwa kuti ibvise kumanikidzwa isati yashanda. Mushure mekusimbisa kuti hapana gasi rakaburitswa, kumanikidzwa kwegeji kwaive zero, izvo zvakafunga zvisirizvo kuti pakanga pasina medium mupombi. Kutaura zvazviri, memory yepombi yaive nekumanikidzwa kwakasara nekuda kwekusakwana kwekuvhura kwevharuvhu yekugeza. Kuyera kwegeji yekumanikidza i4.0mpa, kunyangwe ichisangana nezvinodiwa, asi kana kumanikidzwa kwepombi kwakaderera, kumanikidzwa kwakasara nekuda kwekukanganisa kwekuenzanisa kwegeji yekumanikidza hakugone kuratidzwa.

3. Ruzivo nezvidzidzo

(1) Chero basa rinofanira kuitwa nemazvo, kubviswa kwesimba,Tagout yekukiyabasa, panguva imwe chete vachiita basa rakanaka rekuita nekusimbisa matanho, kuona kuchengetedzeka nekudzora maitiro ese ekushanda.

(2) Simbisa kutarisirwa kwekuchengetedzwa kwemabasa ekuongorora nekugadzirisa, kuvandudza kugona kuziva njodzi, uye kuita basa rakanaka rekudzivirira. Kuongorora kuchengetedzeka kunofanira kuitwa usati watanga basa. Kuongorora nekugadzirisa michina, kunyanya mabasa ekuvhura mapaipi nemidziyo, kunofanirwa kuitwa zvakanaka nekuchenesa, kusunungura kumanikidzwa uye kubvisa zvinhu kuti ive nechokwadi chekuti zvinhu zviri kuparadzaniswa, kubviswa uye kubviswa.
