Thermal power plant tsaona nyaya yekuongorora
Datang a thermal power plant equipment management department yakagadzirira kwete.1 boiler C marasha chigayo chemukati chekugadzirisa chirongwa, mushure mekubvumidzwa kuita.

Zhang Yanqiu, munhu anotarisira C chigayo chekugadzirisa boka rekushanda, uye muongorori wepoinzi akapinda muC chigayo kuti aongororwe, uye akawana kuti C mill centering bracket yakasungwa.Vakasarudza kubata nekuvhurwa kwewelding mune inopisa yekutanga mhepo duct uye yekuisa chisimbiso gland kurongedza kukanganisa kweiyo baffle shaft uye inopisa yekutanga mhepo inoshanduka gadziriso mukushanda.

Li Deyu, mucherechedzi, semunhu mukuru anotarisira basa rekugadzirisa nzvimbo yeC coal mill, akagovera mabasa ekugadzirisa mukirasi yekugadzira upfu, uye akatuma Wang Hongliang naTan Zhe kuti vatore chikamu mubasa rekugadzirisa relding yeC marasha. chigayo musuwo kupisa mhepo mugero.

Masikati, Li Deyu akaita musangano wekirasi ndokuronga basa masikati: Nyanzvi yekirasi yakapwanyika yakasangana nevashandi veDhipatimendi rekugadzira magetsi uye akaronga Li Jun kuti agadzirise ndiro yebaffle yeC coal mill yekupinda yekudziya. nguva imwe.Mugadziri wekirasi yekugadzira upfu anochenesa tsvina inopisa inopisa pamba pamusoro pemhepo yekutanga uye inogadzirisa ndiro yebhaffle nekugadzirisa kwekutanga kwemhepo duct;Wang Zijun, mugadziri wekirasi yekugadzira hupfu, ndiye muchengeti wenzvimbo shoma yekushanda.Li Deyu pane kupisa kwekutanga mhepo duct welding saiti kugamuchirwa.

Li Jun akasvika paC marasha chigayo chekugadzirisa nzvimbo, panguva ino, 6.9 metres papuratifomu yekuvaka scaffolding yakamiswa, Li Deyu, Wang Hongliang, Tan Zhe vari kupinda mugero remarasha rinopisa mhepo yekushanda, Wang Zijun mune inopisa mhepo chiteshi. monitoring.

Li Jun akavhura gonhi rekabati rekutonga pakanzuru yekudzora kabati ine screwdriver mupuratifomu ye6.9-mita kushandura "far control / near control" switch kune "near control" chinzvimbo, ndokudzvanya solenoid vharafu kuti utange switch.Pakanga pasina chekuita mushure mekudhinda kwekutanga, uye zvakadaro hapana chekuita mushure mekudhinda kwechipiri.

Li Jun akashevedzera kune anogadzirisa pamhepo yekupisa yekutanga mhepo panjanji yemamita 6.9 papuratifomu, achibvunza kana bhavhu rekudzora rakafamba?Mugadziri akarova baffle link crank netsoka yake ndokusimudza kuratidza kuti haina kufamba.

Li Jun akavhurawo vheruvhu remusuwo remhepo sosi yeC coal mill inlet yekudziya yekutanga air dynamic insert plate, ine chiratidzo chekunyevera che "Hapana kushanda nebasa revanhu".Panguva ino, iyo inopisa mhepo ine simba plug gonhi inovhurwa, 309 ℃ mweya inopisa inopfapfaidzwa muC marasha chigayo chekupinda kupisa kwekutanga mhepo duct nekumanikidza kwe6kPa, Li Deyu, Wang Hongliang, Tan Zhe vanobatanidzwa muC marasha chigayo. yekupinda tsigiro pasi.

Vashandi vekununura vakapinda kwete.1 boiler C marasha chigayo chekupinda chekupisa iyo yekutanga mhepo duct, nunura vanhu vakabatwa.Asi vose vakasimbiswa kuti vakanga vafa.

Chikonzero chiriporipocho

Maintenance process, repairman Li Jun kutyora kwakakomba kwekushanda.In haina midziyo iri pasi pemamiriro anoenderana nemamiriro ezvinhu, tarisa zita remuchina chiziviso, kuvhura mweya solenoid valve plug gonhi uye hapana "hapana oparesheni mumwe munhu anoshanda" placard air vharafu nemaoko, yekutanga marasha chigayo chinopinza chinopisa mumhepo yakavharwa. C inofamba musuwo wakavhurika, tembiricha i309 ℃, kudzvanywa kuri 6 kpa marasha chigayo chinopinza mweya jekiseni C kupisa mukati memugero, Ikonzeresa kuti njodzi iitike.
