Kugawa ndi kusankha choletsa kuphulika

Zipangizo zofunika kwambiri kuti timvetse momwe zida zowongolera zitsime zimagwirira ntchito, kuziyika ndi kuzisamalira bwino, ndikupangitsa kuti zida zowongolera zitsime zigwire ntchito yake yoyenera ndi choletsa kuphulika. Pali mitundu iwiri ya zoletsa kuphulika zomwe zimafala: choletsa kuphulika kwa mphete ndi choletsa kuphulika kwa ram.

1. Choletsa mphete

(1) Ngati pali chingwe cha chitoliro m'chitsime, pulasitiki ya rabara ingagwiritsidwe ntchito kutseka malo ozungulira omwe amapangidwa ndi chingwe cha chitoliro ndi mutu wa chitoliro;

(2) Mutu wa chitsime ukhoza kutsekedwa bwino pamene chitsime chilibe kanthu;

(3) Pobowola ndi kugaya, kupukusa chidebe, kudula mitengo ndi kusodza, ngati pakhala kusefukira kapena kuphulika, imatha kutseka malo opangidwa ndi kelly pipe, chingwe, chingwe cha waya, zida zogwirira ntchito mwangozi ndi mutu wa chitsime;

(4) Ndi chowongolera kupanikizika kapena chosungira mphamvu chochepa, imatha kukakamiza cholumikizira cha chitoliro cholumikizidwa ndi matako popanda chomangira chopyapyala pa 18°;

(5) Ngati yadzaza kwambiri kapena yaphulika, imagwiritsidwa ntchito kuti itseke bwino ndi ram BOP ndi throttle manifold.

2. Choletsa kuphulika kwa Ram

(1) Ngati pali zida zobowolera m'chitsime, nkhosa yotsekedwa theka yofanana ndi kukula kwa chida chobowolera ingagwiritsidwe ntchito kutseka malo ozungulira a mutu wa chitsime;

(2) Ngati palibe chida chobowolera m'chitsime, ndodo yotsekera yonse imatha kutseka mutu wa chitsimecho mokwanira;

(3) Ngati pakufunika kudula chida chobowolera m'chitsime ndikutseka mutu wonse wa chitsime, chometera tsitsi chingagwiritsidwe ntchito kudula chida chobowolera m'chitsime ndikutseka mutu wonse wa chitsime;

(4) Nkhosa ya nkhosa ya zotchingira kuphulika kwa ng'ombe imalola kunyamula katundu ndipo ingagwiritsidwe ntchito kuyimitsa zida zobowolera;

(5) Pali dzenje la m'mbali pa chipolopolo cha ram BOP, lomwe lingagwiritse ntchito njira yochepetsera kuthamanga kwa mpweya m'mbali mwa dzenjelo;

(6) Ram BOP ingagwiritsidwe ntchito potseka chitsime kwa nthawi yayitali;

3. Kusankha mitundu yosiyanasiyana ya BOP

Zinthu zazikulu zomwe ziyenera kuganiziridwa posankha choletsa kuphulika kwa madzi ndi izi: mtundu wa chitsime, kuthamanga kwa mapangidwe, kukula kwa chivundikiro, mtundu wa madzi opangidwa, momwe nyengo imakhudzira, zofunikira pa chitetezo cha chilengedwe, ndi zina zotero.

(1) Kusankha mulingo wa kupanikizika

Zimatsimikiziridwa makamaka ndi kuthamanga kwakukulu kwa mutu wa chitsime komwe kuphatikiza kwa BOP kukuyembekezeka kupirira. Pali milingo isanu ya kuthamanga kwa BOP: 14MPa, 21MPa, 35MPa, 70MPa, 105MPa, 140MPa.

(2) Kusankha njira

Kukula kwa BOP kumadalira kukula kwa chivundikirocho mu kapangidwe ka chitsimecho, ndiko kuti, chiyenera kukhala chachikulu pang'ono kuposa kukula kwakunja kwa chivundikirocho komwe chalumikizidwa. Pali mitundu isanu ndi inayi ya mainchesi oletsa kuphulika: 180mm, 230mm, 280mm, 346mm, 426mm, 476mm, 528mm, 540mm, 680mm. Pakati pawo, 230mm, 280mm, 346mm ndi 540mm nthawi zambiri amagwiritsidwa ntchito m'munda.

(3) Kusankha fomu yophatikiza

Kusankha njira yophatikizira kumadalira makamaka mphamvu ya kapangidwe kake, zofunikira pakubowola, kapangidwe ka zida zobowola ndi zinthu zothandizira zida.
