Kuiswa kwemavharuvhu ebhora akakwenenzverwa
(1) Kusimudza. Ivhavha inofanira kusimudzwa nenzira yakarurama. Kuchengetedza hunde hwevharuvhu, usasungirire ketani yekusimudza kune handwheel, gearbox kana actuator. Usabvisa zvivharo zvinodzivirira pamigumo miviri yevhavha sleeve usati wapisa.
(2) Welding. Kubatana nepombi huru kunosungirirwa. Hunhu hwemushonga wewelding hunofanirwa kusangana ne "Radiography yeWelded Joints yeDisk Flexion Fusion Welding" (GB3323-2005) Grade II. Kazhinji, welding imwe haigone kuvimbisa zvizere zvese zvikwaniriso. Nokudaro, kana uchiraira valve, mugadziri anofanira kukumbira mugadziri kuti awedzere 1.0m kumativi ose maviri evhavha. Sleeve chubhu, kana welding seam isingakodzeri, pane hurefu hwakakwana kuti ucheke iyo isina kukodzera welding seam uye weld zvakare. Kana vharafu yebhora uye pombi zvakasungirirwa, vharafu inofanirwa kunge iri mu100% yakavhurika zvakazara nzvimbo kudzivirira vharavhavha yebhora kuti isakuvadzwe nekupuruzira welding slag, uye panguva imwechete chengetedza vharafu Kupisa kwechisimbiso chemukati hakuiti. inodarika 140 degrees Celsius, uye matanho akakodzera ekutonhodza anogona kutorwa kana zvichidikanwa.
(3) Vavhavha tsime masonry. Iyo inotora yakakosha dhizaini uye ine hunhu hwekuchengetedza-isina. Usati waviga, isa Pu special anti-corrosion coating kunze kwevharuvhu. Ivhavhavhavha inowedzerwa zvakakodzera maererano nekudzika kwepasi, kuitira kuti vashandi vapedze mabasa akasiyana-siyana pasi. Mushure mekuvigwa kwakananga kwaitwa, zvakakwana kuvaka ruoko ruduku rwevharuvhu zvakanaka. Kune nzira dzakajairika, haigoni kuvigwa zvakananga, uye matsime makuru evhavha anoda kuvakwa, izvo zvinoguma munzvimbo ine ngozi yakavharwa, iyo isingabatsiri kushanda kwakachengeteka. Panguva imwecheteyo, muviri wevhavha pachawo uye zvikamu zvekubatanidza mabhoti pakati pemuviri wevhavha uye pombi zvichave zvakasvibiswa, izvo zvinokanganisa hupenyu hwebasa revhavha.
Chii chinofanira kucherechedzwa mukuchengetedza kwevhavha yebhora yakazara welded?
Nyaya yacho ndeyokuti mumamiriro akavharwa, kuchine mvura yakamanikidzwa mukati memuviri wevhavha.
Chechipiri poindi ndechekuti usati wagadzirisa, tanga wasunungura pombi yekumanikidza uye wozochengeta vharafu iri munzvimbo yakavhurika, wobva wacheka simba kana gasi sosi, wobva wabvisa actuator kubva kubhureki, uye mushure mezvose zviri pamusoro zvinogona kugadziriswa. .
Pfungwa yechitatu ndeyekuona kuti kudzvanywa kwepombi dzepamusoro uye dzezasi dzevhavhavhavhavha yebhora kunonyatso kusunungurwa, uye ipapo disassembly uye kuora kunogona kuitwa.
Iwo mapoinzi mana anofanirwa kungwarira mukuita disassembly uye kubatanidzazve, kudzivirira kukanganisa kwechisimbiso pamusoro pezvikamu, kushandisa maturusi akakosha kubvisa O-ring, uye kuomesa mabhaudhi paflange symmetrically uye zvishoma nezvishoma uye zvakaenzana. panguva yegungano.
Mapoinzi mashanu: Paunenge uchichenesa, mushandisi wekuchenesa anoshandiswa unofanirwa kuenderana nezvikamu zverubha, zvikamu zvepurasitiki, zvikamu zvesimbi uye svikiro rekushanda muvhavha yebhora. Kana iyo yekushanda svikiro iri gasi, peturu inogona kushandiswa kuchenesa simbi zvikamu, uye Kune zvisiri zvesimbi zvikamu, unofanirwa kushandisa mvura yakachena kana doro kuchenesa. Zvikamu zvimwechete zvakaora zvinocheneswa nekunyudzwa nekunyudzwa, uye zvikamu zvesimbi zvezvisiri-simbi zvisina kuora zvinokweshwa nemucheka wakachena uye wakanaka sirika wakanyikwa mukuchenesa, uye mafuta ese anonamatira kumadziro anofanirwa kuve. kubviswa. , tsvina neguruva. Zvakare, haigone kuunganidzwa pakarepo mushure mekucheneswa, uye inogona chete kuitwa mushure mekunge mumiriri wekuchenesa abuda.
