Multiple Activation Bypass Valve (MCBV)

Multiple activation bypass valve ke sete se sekhutšoane se ka buloang le ho koaloa ka makhetlo a mangata. Ka kakaretso e kentsoe BHA e khethehileng joalo ka tataiso, lebelo-up, LWD joalo-joalo. E ka bula le ho koala lesoba la bypass ka nako bakeng sa ts'ebetso e khethehileng ho latela litlhoko tsa maemo a tlase, e le ho matlafatsa ts'ebeliso ea BHA e khethehileng, ho ntlafatsa katleho ea tlhahiso le ho fokotsa kotsi ea taolo ea seliba.

Haeba u na le thahasello ho Vigor's stabilizer e khethehileng e nang le Multiple activation bypass valve kapa lisebelisoa tse ling tse amehang tsa theolelo, u ka lula u ikopanya le rona ho ithuta haholoanyane.

①Ntlafatsa ho sebetsa ha lisebelisoa tse khethehileng tsa ho cheka:

●Ho feto-fetoha ha maemo:Multiple Activation Bypass Valve (MCBV) e ka buloa le ho koaloa ka makhetlo a mangata, ho lumella likopano tse khethehileng tsa lisebelisoa tsa ho phunya hore li ikamahanye le maemo a fapaneng a ho theoha le litlhoko tsa ts'ebetso.

●Tšebelisano:E etselitsoe hore e tsamaisane le lisebelisoa tse fapaneng tse khethehileng tsa ho phunya (joalo ka lisebelisoa tsa ho phunya, lisebelisoa tsa ho rema lifate, joalo-joalo).

●Ho ikamahanya le maemo:E ka sebelisoa ka mefuta e fapaneng ea liliba (liliba tse otlolohileng, liliba tse lebisang, liliba tse rapameng), ho eketsa maemo a ts'ebeliso ea likopano tse khethehileng tsa lisebelisoa tsa ho cheka.

●Tshireletso:Ka ho laola phallo ea mokelikeli, likarolo tse bonolo tsa "hole hole assembly" (BHA) li sirelelitsoeng le ho lelefatsa bophelo ba bona ba ts'ebeletso.

② Ntlafatsa katleho ea tlhahiso:

● Fokotsa palo ea maeto: Mesebetsi e mengata (e kang ho plugging, ho hloekisa liliba) e ka phethoa ntle le ho cheka, e leng ho boloka nako haholo.

● Karabelo e potlakileng: E khona ho fetola kapele ho ea ka maemo a ka tlas'a lefatše, ho fokotsa nako ea ho leta le ho etsa liqeto.

③ Fokotsa likotsi tsa taolo ea seliba:

● Ts'ebetso ea ho koala ka bohona:E koala ka tsela e iketsang ha pompo e emisa, e thibela phello ea U-tube le ho fokotsa kotsi ea ho raha seliba.
●Ho sebetsana le mathata ka nako:U ka arabela ka potlako maemong a tšohanyetso a ka tlas'a lefatše, joalo ka ts'ebetso ea ho plugging ka nako.
● Fokotsa ho khoptjoa:Likotsi tsa taolo ea seliba tse amanang le ho khoptjoa (joalo ka ho se tsitse ha lebota, ho raha liliba, joalo-joalo) lia fokotseha.
