Yintoni isakhiwo kunye nomgaqo wokusebenza wevalve yokubhoboza i-bypass valve?

Ivalve ye-bypass yesixhobo sokomba yivalve yokhuseleko yogcino lwenkqubo yokujikeleza.Xa i-drill drill nozzle ivaliwe ngenxa yezizathu ezahlukeneyo kwaye iqula alikwazi ukubulawa, ukuvula ivalve yesixhobo sokugrumba kunokubuyisela ukujikelezwa kolwelo oluqhelekileyo kwaye kuqhutywe kwimisebenzi efana nokubulala, phantsi kweemeko eziqhelekileyo, ngaphambi kokomba ioli kunye umaleko wegesi, ivalve yesixhobo sokugrumba i-bypass iqhagamshelwe kwindawo emiselwe kwangaphambili yomtya wokubhola.

1) Ubume besixhobo sokuqhuba i-valve ye-bypass

Lo mfanekiso ungentla ngumzobo wesakhiwo sevalve yesixhobo sokugrumba.Ubukhulu becala yenziwe ngumzimba wevalvu, isihlalo sevalve yesilayidi sendibano, umngxuma odlulayo, ibhola yentsimbi, iphini, "O" uhlobo lomsesane wokutywina, njl.

2) Umgaqo osebenzayo we-valve yokubhoboza isixhobo sokugqitha

Nje ukuba kufunyaniswe ukuba umngxuma wamanzi we-drill bit uvalekile kwaye awunakuvuleka, susa i-kelly kwaye uphose ibhola, emva koko uqhagamshele i-kelly ukuze ibhola iwele kwisitulo sevalve yesixhobo sokubhola.Emva kokupompa nge-displacement encinci, ngokude nje ukuba uxinzelelo lwempompo luyenyuka ukuya Xa uxinzelelo lufikelela kwixabiso elithile, i-pin esisigxina iya kunqunyulwa, ibangele ukuba isihlalo se-valve sihambe phantsi kude kube yilapho umngxuma we-bypass uvuliwe ngokupheleleyo.Uxinzelelo lwempompo luya kuhla, ngaloo ndlela luseka umjelo omtsha wokujikeleza, kwaye umsebenzi wokwakha unokuqalisa.

3) Ukusetyenziswa kwevalve ye-bypass yesixhobo sokomba

(1) Ukugcina ulwelo lokomba emingxunyeni lucocekile, ivelufa yokudlula kufuneka ivulwe kwangethuba ukuze kuthintelwe ukuvaleka komngxuma wamanzi we-drill bit.

(2) Ibhola yentsimbi yevalve ye-bypass kufuneka ilungiswe kwaye ibekwe ngaphambi kokusetyenziswa ukuze ifikeleleke ngexesha elifanelekileyo xa kuyimfuneko.

(3) Ukuqinisekisa ukuba umkhono wokutyibilika womngxuma wokudlula wevalve yokudlula efunekayo ungavuleka ngokutyibilikayo, kucetyiswa ngokubanzi ukuba ivalve yokudlula ifakwe phakathi kwekhola yokubhoboza kunye nombhobho wokubhoboza okanye umgama ongama-30 ukuya kuma-70m ukusuka kwindawo yokusebenzela. khangela ivalve.Iivalve ze-Bypass zemigodi ethe tye kunye namaqula atenxe kakhulu afakwe kwizixhobo zokomba kwi-50 ° ukuya kwi-70 ° yecandelo lomthombo.

(4) Isixhobo sokubhoboza ivalve ye-bypass kufuneka ilawulwe ngokusetyenziswa kwezixhobo ezikhethekileyo zokungena equleni.Kuyafuneka ukuba udale ikhadi lokurekhoda ukurekhoda ngokweenkcukacha ixesha lokusetyenziswa komngxuma kunye nezinye iiparitha ezifanelekileyo.Ngaphambi komsebenzi ngamnye wokomba, amagcisa kunye nabombi baya kukhangela ukuba kukho imiqobo, ukuvuza kunye nokuvuza.Ukungaphumeleli kwetywina, njl.
