1. Nzira yekuchenesa
Iyo welding slag, ngura uye slag mupombi inokonzeresa kuvharika kana kudhumhana mune orifice, kutungamira chikamu uye gomba rechiyero chevhavha yevhavha yevhavha, zvichikonzera kudhonza nekukwenya pamusoro peiyo yepakati pevhavha uye yekutungamira nzvimbo, uye indentation panzvimbo yekuvharira. Izvi zvinowanzoitika muchikamu chekutanga chekushanda kwehurongwa hutsva uye mushure mekugadzirisa. Iyi ndiyo inonyanya kukanganisa. Muchiitiko ichi, zvakakosha kubvisa slag yekuchenesa, uye kukuya kana nzvimbo yekuvhara yakakanganiswa; panguva imwe cheteyo, vhura puragi yepasi kuti ubvise slag inowira mukati mevharuvhu yevhavha kubva pagomba rekuenzanisa, uye bvisa pombi. Isati yatanga kushanda, vharuvhu yekudzora ichavhurwa zvizere uye yepakati ichayerera kwenguva yakati isati yapinda mukushanda kwakajairika.
2. External scouring nzira
Kana vharafu yakajairwa ichishandiswa kudzora svikiro iri nyore kunayisa uye iine zvimedu zvakasimba, inowanzovharika pane orifice uye gwara. Kutsvaira gasi uye steam zvinogona kubatanidzwa pazasi plug yevhavha yevhavha yepasi. Kana vheji yakavharwa kana yakanamatira, vhura gasi rekunze kana vheji yemhepo kuti upedze basa rekutsvaira pasina kufambisa valve yekudzora, kuitira kuti vheji ishande zvakanaka.
3. Kuiswa kwepipeline sefa
Kune diki caliber control valve, kunyanya yekupedzisira diki yekuyerera yekudzora vharafu, iyo throttle clearance idiki kwazvo, uye hapafanirwe kunge paine slag mukati. Kana pakavharika, zviri nani kuisa sefa pane pombi pamberi pevharuvhu kuti ive nechokwadi chekupfuura kwakatsetseka kwepakati. Kuvharuvhu yekudzora ine positioner, chinomisikidza hachishande zvakajairwa, uye chikanganiso chakanyanya kuvharika kwechiteshi chayo chekutsikitsira. Nokudaro, kana uchishanda nechinzvimbo, nzvimbo yemhepo inofanira kubatwa zvakanaka. Iyo yakajairika nzira ndeyekuisa mhepo sefa pressure yekudzikisa vharafu pamhepo sosi pombi pamberi penzvimbo
4. Wedzera throttle clearance
Semuenzaniso, zvimedu zvakasimba mukati kana welding slag uye ngura yakashambidzwa kunze kwepombi haigoni kupfuura nepakati pemvura inoputika uye inokonzera kuvhara, jamming uye zvimwe zvikanganiso. Idzo nzvimbo dzinotenderedza dzine hombe yekupuruzira clearance, senge valve core uye sleeve ine hwindo uye yakavhurika throttling nzvimbo, inogona kushandiswa pachinzvimbo. Nemhaka yokuti nzvimbo ye-throttling yakanyanyisa pane kugovera circumferentially, kukanganisa kunogona kubviswa nyore nyore. Kana iri vharuvhu yechigaro chimwe chete kana vharuvhu yezvigaro zviviri, iyo plunger yakaita sevhavha core inogona kuchinjwa kuita V-yakaita sevhavha core kana sleeve valve. Semuyenzaniso, kaviri chigaro vharafu mumushonga wemakemikari inowanzobatwa, saka zvinokurudzirwa kushandisa sleeve valve, uye dambudziko rinogadziriswa pakarepo.
5. Medium scouring nzira
Nekushandisa simba rekutsvaira repakati pachayo, rinogona kukwenya nekubvisa zvinhu zviri nyore kudonha nekuvharika, kuitira kuvandudza anti blocking basa revharuvhu. Nzira dzakajairika ndedzinotevera: ① shanduko kuyerera yakavharwa mhando; ② shandisa yakakwenenzverwa vharafu muviri; ③ isa iyo throttle orifice panzvimbo yakanyanya scour point, uye teerera kuti uvandudze kudzivirira kwekukukurwa kwezvinhu.
6. Iyo yakananga kuburikidza nenzira inoshandurwa kuita angular nzira
Iyo yakatwasuka kuburikidza nekuyerera inverted s kuyerera, nzira yekuyerera yakaoma, uye kune dzakawanda nzvimbo dzakafa munzvimbo yepamusoro nepasi, iyo inopa nzvimbo yekunaya kwepakati. Angular yekubatanidza, iyo yepakati sekunge inoyerera nepakati pe90 ℃ gokora, yakanaka scouring kuita, diki yakafa nzvimbo, iri nyore kugadzira mutsetse wekuyerera. Naizvozvo, kana iyo yakatwasuka kuburikidza nekudzora vharafu yakavharika zvishoma, inogona kuchinjwa kuita angle valve.
