Classification uye kusarudzwa kwe blowout preventer

Midziyo yakakosha yekunzwisisa mashandiro emidziyo yekudzora zvakanaka, kuisa nekuchengetedza nemazvo, uye kuita kuti midziyo yekudzora tsime itambe basa rayo rakakodzera ndiyo inodzivirira. Kune marudzi maviri eanojairwa kuvhuvhuta kudzivirira: ring blowout preventer uye ram blowout preventer.

1.Ring preventer

(1) Kana pane tambo yepombi mutsime, rubber core inogona kushandiswa kuvhara annular space yakagadzirwa netambo yepombi uye tsime;

(2) Musoro wetsime unogona kuvharwa zvizere kana tsime risina chinhu;

(3) Muchigadziro chekuchera nekugaya, kugaya, kutema matanda uye kubata hove pasi, kana paine mafashama kana kuputika, inogona kuvhara nzvimbo yakagadzirwa nekelly pipe, cable, tambo yewaya, maturusi ekubata njodzi uye wellhead;

(4) Nekudzvanyirira kudzoreredza regulator kana diki simba rekuchengetedza, inogona kumanikidza butt welded pombi yakabatana isina yakanaka buckle pa18 °;

(5) Kana pakafashukira zvakanyanya kana kuputika, inoshandiswa kuwana yakapfava yekuvhara mukati negondohwe BOP uye throttle manifold.

2.Ram blowout preventer

(1) Kana paine maturusi ekuchera mutsime, gondohwe rakavharwa nehafu rinoenderana nehukuru hwemudziyo wekuchera rinogona kushandiswa kuvhara nzvimbo yemhete yetsime;

(2) Kana pasina mudziyo wekuchera mutsime, gondohwe rakazara rekuvharisa rinogona kunyatsovhara musoro wetsime;

(3) Kana zvichidikanwa kucheka chigadziro chekuchera mugomba uye kunyatsosimbisa musoro wetsime, gondohwe rekuveura rinogona kushandiswa kucheka chigadziro chekuchera mugomba uye kunyatsovhara musoro wetsime;

(4) Gondohwe rezvimwe zvinodzivirira kuputika kwemakondohwe rinobvumira kutakura mitoro uye rinogona kushandiswa kumisa maturusi ekuchera;

(5) Pane gomba reparutivi pane goko regondohwe BOP, rinogona kushandisa gomba reparutivi throttling pressure relief;

(6) Ram BOP inogona kushandiswa kwenguva refu yekuisa chisimbiso chetsime;

3.Kusarudzwa kweBOP kusanganiswa

Zvinhu zvikuru zvinofanirwa kutariswa mukusarudzwa kwe hydraulic blowout kudzivirira musanganiswa ndeiyi: tsime mhando, kuumbwa kwekumanikidza, saizi yekasi, kuumbwa kwemvura yemhando, mamiriro ekunze, zvinodiwa zvekuchengetedza kwezvakatipoteredza, nezvimwe.

(1) Sarudzo yedanho rekumanikidza

Iyo inonyanya kutsanangurwa neyakaomesesa tsime dzvinyiriro iyo BOP musanganiswa inotarisirwa kumira. Kune mashanu ekumanikidza mazinga eBOP: 14MPa, 21MPa, 35MPa, 70MPa, 105MPa, 140MPa.

(2) Kusarudza nzira

Iyo dhayamita yeiyo BOP musanganiswa inoenderana nehukuru hwecasing mune dhizaini yedhizaini, ndiko kuti, inofanira kunge yakakura zvishoma pane yekunze dhayamita yekasi iyo yakasungirirwa. Kune marudzi mapfumbamwe emadhayamita ekudzivirira kuvhuvhuta: 180mm, 230mm, 280mm, 346mm, 426mm, 476mm, 528mm, 540mm, 680mm. Pakati pavo, 230mm, 280mm, 346mm uye 540mm inowanzoshandiswa mumunda.

(3) Sarudzo yemusanganiswa fomu

Kusarudzwa kwefomu yekubatanidza kunonyanya kuenderana nekumanikidza kwekugadzira, kudhirowa kwemaitiro ekudhirowa, kudhiraivha chishandiso chimiro uye midziyo inotsigira mamiriro.
