Maitiro ekupedzisa esimbi pombi yakakosha uye akakosha ekubvisa zvikanganiso zvezvigadzirwa zvechigadzirwa. Hydraulic test, nezvimwewo), kuchema, kuenzana kuyerwa, kuyera, kupenda, kudhinda uye matanho ekuputika. Zvimwe zvinokosha-chinangwa masimbi mapipi anodawo pamusoro pekupfura kuputika, muchina kugadzirisa, anti-corrostion kurapwa, nezvimwe.
.
⒈ Chinangwa chechipfuva chesimbi chinobuda.
① Bvisa kukotama
② Deredza kuwanda kweiyo simbi pombi
⒉ Kuremara kwemhando yemhando inokonzerwa neiyo pombi panguva yekugadzirisa
⒊ Unhu hwekutadza mune simbi pombi yakatwasuka: mapepa esimbi haana kurwiswa
(ii) Simbi pombi yekukuya uye kucheka kuremara uye kudzivirira kwavo
Chinangwa chekukuya kumusoro kwezvirongwa zvechibage zvembambo
2.
⒊ Simbi Pippe Surching Kukuya Inofanirwa Kuwanzosangana nezvinodiwa zvinotevera:
Pashure pokukasira pamusoro peneli pombi inogadziriswa, rusvingo rwedenga renzvimbo yakagadziridzwa haigone kutsauka madziro emadziro, uye dhaya rekunze renzvimbo yakagadziridzwa inofanira kuita zvinodiwa pombi yechigaro chesimbi.
✓ADHesa pamusoro penzvimbo yesimbi pasi, zvinodikanwa kuti urambe uri pasi pebiti yesimbi seyakagwinya curved nzvimbo (yakawandisa arc). Kukundwa kwakadzika: upamhi: kureba = 1: 6: 8
③ Paunenge uchikuya pombi simbi seyese, hapasave nekunyora kana pachena mapepa emapuranga pane pamusoro penzvimbo yesimbi.
④Nzvimbo yekugeza yekukuya kweiyo mbira hadzizopfuura iyo nhamba yakataurwa muyero.
⒋ Iko kuremara kukuru kwakakonzerwa neiyo pombi kuputika kunoputika
Kuvandudza kurwadza kwepombi yesimbi uye kuderedza kuova kweiyo mbeva chimbuzi ndidzo prerequisites yekuita kuti kuve nemhando yekucheka yeiyo pombi yesimbi. Zvipfeko zvesimbi zvine mwero wakakura zvemukati, murazvo wekucheka unofanira kudzivirirwa zvakanyanya sezvinobvira kuderedza kuitika kwepombi yekupedzisira.
(iii) simbi pombi pamusoro kugadzirisa urema uye kudzivirira kwavo
⒈ Simbi pombi pamusoro pekugadzirisa kunyanya inosanganisira: Kumusoro kupfurwa kupenya, zvakazara pamusoro pekuchera uye michina yekugadzirisa.
► Chinangwa: Kuenderera mberi nekuvandudza iwo mamiriro epasi uye kurongeka kwemukati kweiyo simbi pombi.
Zvishandiso zvekuchera zvakazara kwesimbi yekunze kwechibayiro chesimbi chinonyanya kusanganisira: mabhanhire anowedzera, achiraira mavhiri uye achikuya zvishandiso zvemachinda. Mushure mekukuvara kwese kweiyo mbeva pombi, iyo nzombe yechipfuva pamusoro pechiratidzo chesimbi chinogona kubviswa zvachose, kupedzisa kwepombi kunogona kuvandudzwa, uye pamusoro peganda renje rinogona kubviswa. Mamwe madiki akaremara senge madiki madiki, mitsara yebvudzi, makomba, makomba, etc.
① Shandisa bhandi rinobvaruka kana kugeda vhiri kuti ugone kugeda pasi pegomba renje. Mhedzisiro yemhando yepamusoro iyo inogona kuitika inosanganisira: Ganda dema pamusoro peiyo mbira, yakawandisa madziro, flatgons (mapuranga, mapuranga uye akapfeka mamaki, nezvimwe.
② Ganda dema pamusoro pechiratidzo chesimbi rinokonzerwa nekukuya kwemari kuve madiki kana makomba ari pamusoro peiyo simbi pombi. Kuwedzera huwandu hwekukuya kunogona kubvisa ganda dema pane iyo simbi pombi.
③ Simbi pombi madziro ibvi kunze kwekushivirira nekuti kutsauka kwakashata kwemadziro emadziro kweiyo mbichana pombi pachayo yakakura kana huwandu hwekugeza hwakanyanya.
④ Inopisa pamusoro penzvimbo yesimbi inonyanya kukonzerwa nekunyanyisa kushushikana pakati peiyo vhiri rekunyevera nepamusoro pegomba renje
⑤ Deredza huwandu hwesimbi pombi yekukuya panguva imwe. Shandisa iyo coarse yekukwevera vhiri kuti isingaomeswe yekugeza pombi uye yakanaka yekuvhuvhuya yekukuya kwakanaka kugeda. Izvi hazvigone kudzivirira nzvimbo inopisa pombi yesimbi, asi zvakare kuderedza iyo mapfekero ekupfeka anogadzirwa pamusoro peiyo simbi pombi.
⒋ Kupfurwa Peening pane simbi pombi pamusoro
① Simbi PIPE Surch Shot Peening ndeyekupfura iron kupfura
Saizi uye kuomarara kweiyo jecha kupfurwa uye nekumhanya kwejekiseni zvakakosha zvinhu zvinokanganisa kunaka kwekupfura pamusoro peiyo simbi pombi.
⒌ Simbi pombi pamusoro pemachina
①SE STEEL PIPES ine yakakwirira yemukati uye yekunze mhando zvinodiwa zvinodiwa zvekugadzirisa zvekuita.
②Kunyatso kukwana kwehukuru, mamiriro emusoro uye curvature yemibayiro yemakiromini haina kugadziriswa nemapipi anopisa-akaomeswa.
Muchidimbu, maitiro ekupedza chinhu chakakosha uye chakakosha kukosha kuti uve nechokwadi chehunhu hwema pombi. Kusimbisa basa rekupedza maitiro kuchabudirira kuenderera mberi nekuenderera mberi nekuvandudza kunaka kwesimbi pombi.
