Iyo blade yecasing scraper inobuda sei mushure mekumhanya tsime?

Mushure mecasing scraperkumhanya kutsime, kazhinji inowedzerwa kuburikidza neimwe mechanical chimiro.Iyo chaiyo yekushanda maitiro inogona kunge iine mimwe misiyano, asi kazhinji inosanganisira anotevera matanho:

Kugadzirira: Usati wamhanya tsime, tarisa blade mamiriro emukororo kuti uone kuti hapana kukuvadzwa kana kupfeka, iva nechokwadi chokuti kuwirirana pakati pe blade uye casing scraper haisi kusununguka kana kukuvara.

Isa scraper: Batanidza scraper kumaturusi ekudzika uye uchengetedze ne nut kana imwe mudziyo wekubata.Ita shuwa kuti wiper yekubatanidza yakachengeteka kudzivirira kusunungura kana kutenderera panguva yekumhanya.

Maitiro ekuwedzera ekushanda: Casing scrapers inowanzova nemichina yekuwedzera nzira dzinoshandiswa kudzora kuwedzera uye kubvisa blade.Nzira yekushanda inogona kusiyana zvichienderana nerudzi rwe scraper, asi dzinowanzoshanda mune imwe yenzira dzinotevera:

a.Rotary: Nekutenderedza chikamu chepamusoro chechishandiso kana kuburikidza neplug yakabatana, blade inotenderera newachi kana kuchinjika kuitira kuti blade ibude kubva pasi pe scraper.

b.Push-pull: Iyo scraper blade inosundirwa kunze kana kudhonzwa kumashure kubva pasi peiyo scraper nekusundidzira uye kudonhedza pasi chikamu chepamusoro chetsime rekushandisa kana kuburikidza neplug yakabatana.

c.Hydraulic kana pneumatic: Kuburikidza ne hydraulic kana pneumatic system, chengetedza kuwedzera uye kuwedzera kwe scraper blade.Nekudzora vharafu, mvura kana gasi inogona kuunzwa kuita kuti blade yekukwenya iwedzere kana kubvisa.

Blade extension:Maererano nekugadzirwa kwekutsvaira, kuburikidza nekushanda kwakakodzera kwemaitiro ekuwedzera, ita basa rinoenderana nekuita kuti blade iwedzere kune yaunoda.Kutenderera, kusunda uye kudhonza, kana hydraulic/aerodynamic masimba anowanzo shandiswa kuwana blade kuwedzera.

Kukwesha kushanda: Kana blade ichinge yawedzerwa panzvimbo, scraping operation inogona kuitwa.Iyo blade ye scraper inobvisa sediment uye chiyero chakasungirirwa kune lining ye casing kuti ichenese uye irambe yakavhurika.

Kuti ave nechokwadi chekuchengetedzwa uye kubudirira kwekushanda, mutyairi anofanirwa kujairana nemirayiridzo yekushanda ye scraper uye kushanda maererano nemitemo yakachengeteka yakachengeteka.Pamusoro pezvo, zvishandiso uye maturusi zvinofanirwa kuchengetedzwa zviri muchimiro chakanaka uye chero chiyero chekuchengetedza chinoshanda uye mirau inofanirwa kucherechedzwa isati yaitwa downhole.
