Vharuvhu yeSimbi Yakagadzirwa neFlanged End
✧ Tsananguro
Mavharuvhu egedhi esimbi akagadzirwa anowanzo shandiswa mumaindasitiri nekuda kwekuvakwa kwawo kwakasimba uye kugona kutsungirira mamiriro ekumanikidzwa kwakanyanya uye tembiricha. Anowanzo shandiswa muindasitiri yemafuta negesi, mafekitori emagetsi, uye mafekitori epetrochemical. Heano mamwe mabhenefiti akakosha uye mabhenefiti emavharuvhu egedhi esimbi akagadzirwa: Akasimba uye Anogara: Mavharuvhu egedhi esimbi akagadzirwa achishandisa nzira yekuumba, iyo inoita kuti ave akasimba zvakanyanya uye anodzivirira kumanikidzwa kwemakanika. Izvi zvinoita kuti akwanise munzvimbo dzinoda simba rakawanda uko kugara kwenguva refu kwakakosha. Kuramba Kumanikidzwa Kwakanyanya uye Tembiricha: Mavharuvhu aya akagadzirwa kuti ashande mashandisirwo ekumanikidzwa kwakanyanya uye tembiricha yakakwira, achipa mhinduro yakavimbika yekudzora kuyerera mumamiriro ezvinhu akaoma ekushanda. Hunhu Hwakanaka Hwekuvhara: Ane hunhu hwakanaka hwekuvhara, zvinobudirira kudzivirira kubuda kwemvura kana vharuvhu yavharwa. Izvi zvakakosha pakuchengetedza kusimba kwesystem uye kudzivirira kurasikirwa nemvura. Kurasikirwa Kushoma Kwekumanikidzwa: Kana yakavhurwa zvizere, mavharuvhu esimbi akaumbwa anopa kurasikirwa kushoma kwekumanikidzwa, zvichibvumira kurongeka kwakanaka kwekuyerera uye kushandiswa kwesimba kushoma. Kushanduka-shanduka: Akakodzera mvura dzakasiyana-siyana, zvichiita kuti akwanise kushandiswa mumaindasitiri akasiyana-siyana. Kutevedzera Maitiro: Mavharuvhu esimbi akaumbwa anowanzogadzirwa uye kugadzirwa zvichienderana nezvinodiwa nemaindasitiri, zvichiita kuti avimbike uye ashande zvakachengeteka. Kazhinji, mavharuvhu esimbi akaumbwa anokosheswa nekuda kwesimba rawo, kugara kwenguva refu, kuramba kupisa kwakanyanya uye kupisa, hunhu hwakanaka hwekuvharira, uye kushanduka-shanduka, zvichiita kuti ave sarudzo inofarirwa munzvimbo dzinodiwa mumaindasitiri.
✧ Zvinhu zviri muvharuvhu yegedhi yesimbi yakagadzirwa neAPI 602
1. Chimiro chacho chiri nyore kupfuura vharuvhu yegedhi, uye zviri nyore kugadzira nekugadzirisa.
2. Nzvimbo yekuvharira haisi nyore kupfeka nekukwenya, uye kushanda kwekuvhara kwakanaka. Hapana kutsvedza pakati pedhisiki revharuvhu nepamusoro pekuvhara kwemuviri wevharuvhu pakuvhura nekuvhara, saka kupera nekukwenya hakusi kwakakomba, kushanda kwekuvhara kwakanaka, uye hupenyu hwebasa hwakareba.
3.Pakuvhura nekuvhara, kurovera kwedhisiki kudiki, saka kukwirira kwevharuvhu yekumisa kudiki pane kwevharuvhu yegedhi, asi hurefu hwechimiro hwakareba kupfuura hwevharuvhu yegedhi.
4.Torque yekuvhura nekuvhara yakakura, kuvhura nekuvhara kwakaoma, uye nguva yekuvhura nekuvhara yakareba.
5. Kuramba kwemvura kwakakura, nekuti nzira yepakati mumuviri wevharuvhu inotenderera, kuramba kwemvura kwakakura, uye kushandiswa kwesimba kwakakura.
6. Kufamba kwepakati nepakati Kana kumanikidzwa kwepakati nepakati PN ≤ 16MPa, inowanzo famba nepakati, uye kuyerera kwepakati nepakati kunokwira kubva pasi pevharuvhu disc; kana kumanikidzwa kwepakati nepakati PN ≥ 20MPa, inowanzo famba nepakati, uye kuyerera kwepakati kunodzika kubva pamusoro pevharuvhu disc. Kuti chisimbiso chiwedzere kushanda. Kana ichishandiswa, vharuvhu yepasi inogona kungofamba nepakati nepakati, uye kuyerera kwepakati hakugone kuchinjwa.
7. Dhisiki rinowanzo pwanyika kana rakavhurika zvizere.
✧ Mabhenefiti evharuvhu yegedhi yesimbi yakagadzirwa neAPI 602
Munguva yekuvhura nekuvhara vharuvhu yesimbi yakagadzirwa, nekuti kukweshana kuri pakati pedhisiki nepamusoro pekuvhara kwemuviri wevharuvhu kudiki pane kwevharuvhu yegedhi, haipfeki.
Kuvhurika kana kuvharwa kwesimbi yevharuvhu kupfupi, uye ine basa rekucheka rakavimbika, uye nekuda kwekuti shanduko yechigaro chevharuvhu inoenderana nekusvetuka kwedhisiki revharuvhu, yakakodzera kwazvo kugadzirisa mwero wekuyerera. Saka, rudzi urwu rwevharuvhu rwakakodzera zvikuru kuchekwa kana kudzorwa uye kupwanywa.

✧ Basa reKutengesa Mushure meKutengeswa
Semugadziri wesimbi yakagadzirwa nehunyanzvi uye mutengesi kunze kwenyika, tinovimbisa kupa vatengi basa repamusoro-soro mushure mekutengesa, kusanganisira zvinotevera:
1. Ipai nhungamiro yekushandiswa kwechigadzirwa uye mazano ekugadzirisa.
2. Kana paine kutadza kunokonzerwa nematambudziko emhando yezvigadzirwa, tinovimbisa kupa rutsigiro rwehunyanzvi nekugadzirisa matambudziko munguva pfupi iri kutevera.
3. Kunze kwekukuvadzwa kunokonzerwa nekushandiswa kwakajairika, tinopa mabasa ekugadzirisa nekutsiva mahara.
4. Tinovimbisa kupindura nekukurumidza kune zvinodiwa nevatengi munguva yewarandi yechigadzirwa.
5. Tinopa rubatsiro rwehunyanzvi kwenguva refu, mazano epamhepo uye masevhisi ekudzidzisa. Chinangwa chedu ndechekupa vatengi ruzivo rwakanakisisa rwebasa uye kuita kuti ruzivo rwevatengi ruve nyore uye runonakidza.
