Kutheni i-DTH isando ingasebenzi kakuhle
Oct 22, 2024
Isando se-DTH sinokwahlulwa sibe luhlobo lwevalve ye-DTH isando kunye nesando se-DTH esingenavalo ngokwendlela yokuhambisa umoya. Iimpawu eziphambili zokungaphumeleli kwesando se-DTH yi-DTH hammer non-impact, impembelelo ebuthathaka kunye nefuthe eliphakathi.
Isizathu 1: Ukwenziwa Kweziphene
Umdlalo phakathi kwe-DTH hammer piston kunye ne-cylinder liner iqinile, kwaye ubude obuhambelanayo bude, kwaye ukuchaneka kwe-machining kunye nokugudiswa komhlaba kufuneka kube phezulu, okudinga i-cylindricity ephezulu kakhulu yepiston kunye ne-cylinder liner. Ukuba i-cylindricity ayiqinisekiswanga, ipiston iya kuba ne-directional okanye i-intermittent sticking, kwaye ekugqibeleni intonga ye-drill inokufuneka iphakanyiswe kwaye ikhululwe rhoqo ukwenzela ukugcinwa kwesando se-DTH.
Ukongezelela, ukuqina kwe-casing yangaphandle ye-hammer ye-DTH nayo yinto ebalulekileyo ethintela ubomi benkonzo yesando se-DTH. Ukuba ukuqina kwayo akulunganga, isando se-DTH siya konakala ngenxa yokungqubana rhoqo nodonga lwequla ngexesha lokomba; xa isando se-DTH singasebenzi, kudla ngokuyimfuneko ukungcangcazela, ukuchithwa kunye nokucoca i-hammer ye-DTH, eya kwandisa umonakalo we-casing yangaphandle ye-hammer ye-DTH. Utshintsho; kunye nokuguqulwa kwe-casing yangaphandle kuya kubangela ukuba iindawo zangaphakathi zesando ze-DTH ziboshwe kwaye azikwazi ukuchithwa, ekugqibeleni ziza kubangela ukuba i-hammer ye-DTH ikhutshwe ngokuthe ngqo.
Isizathu 2: I-Backstop Seal ye-DTH Hammer Tail ayithembekanga
Okwangoku, umsila we-DTH hammer uxhotyiswe nge-valve yokutshekisha, kwaye isakhiwo sayo siboniswe kumzobo. Ifom yokutywina ixhomekeke ikakhulu kuxinzelelo lwe-deformation ye-rubber cap okanye i-O-ring efakwe kwi-conical cap yesinyithi ukwenza ukutywinwa kwe-backstop. Umsebenzi wayo we-backstop uqondwa ngumzimba olulastiki, kwaye umzimba olastiki ngokubanzi unesixhobo esikhokelayo.
Le ndlela yokutywina inezi ngxaki zilandelayo:
(1) Kukho ukungqubuzana phakathi kwentwasahlobo kunye nesixhobo sesikhokelo, esiya kuchaphazela isantya sokunqunyulwa kwevalve yokukhangela;
(2) Ukunyanzeliswa rhoqo kunye nokuxutywa kwezinto zokutywina irabha ixesha elide kuya kubangela ukuguga okugqithisileyo; (3) Umthombo udiniwe kwaye wonakaliswe, okukhokelela ekungaphumeleli kwetywina lomva;
(4) Xa igesi imisiwe, uxinzelelo lomoya ngaphakathi kwesando se-DTH luyancipha ngokukhawuleza, lubangela ukuba i-rock powder okanye umxube we-liquid-solid ubuyele kumqolo ongaphakathi wesando se-DTH, oya kubangela ukuba i-piston ibambelele;
5 chips ngaphandle kokuchaphazela umsebenzi.
Isizathu 3: Intloko ye-DTH Hammer ayinayo itywina
I-dill bits entloko yesando se-DTH zonke zibonelelwa ngomngxuma wokukhupha ukunxibelelana nezantsi kwequla, kunye ne-dill bits kunye nesando se-DTH zidibaniswe yi-splines, kwaye i-gap efanelekileyo inkulu.
Xa i-diving surface idibene ngexesha lenkqubo yokugaya okanye i-cementing fluid kufuneka yongezwe ngenxa yobunzima bokwakheka kakuhle, kukho ubuninzi bemixube yolwelo kunye neqinile kumngxuma ongezantsi kunye nomsantsa phakathi kodonga lomthombo kunye nombhobho wokubhobhoza. Xa kusetyenziswa i-cementing fluid, ukunikezelwa kwegesi kuya kumiswa kwakhona, ukwenzela ukuba i-valve yokutshekisha ekupheleni kwesando se-DTH iya kuvalwa ngokukhawuleza. Ukucocwa komkhono we-spline. Emva koko, ihamile ye-DTH ifana nekomityi yamanzi engenanto ijonge phantsi kulwelo. Irhasi evalelwe kumgodi wangaphakathi wesando se-DTH ngokuqinisekileyo iya kunyanzeliswa lulwelo lwangaphandle. Ulwelo olungakumbi kumngxuma wehamile. Nangona kunjalo, ukuba amanzi amaninzi kakhulu angena kumngxuma ongaphakathi wehamile ye-DTH, ezinye iziqendu ziya kuziswa kwi-piston motion pair ye-internal cavity, eyonyusa kakhulu i-frequency ebambekayo yepiston.
Kwangaxeshanye, ukuba i-cuttings efakwe phakathi kwepiston kunye nobuso besiphelo soqhagamshelwano lwe-dill alukwazi ukususwa ixesha elide, ininzi yempembelelo yamandla e-piston iya kuthatyathwa yi-cuttings kwaye ayikwazi ukuhanjiswa ngokufanelekileyo phantsi, oko kukuthi, impembelelo ibuthathaka.
Isizathu 4: Dill Bit Wanamathela
Ibhilidi ye-dill kunye nesando se-DTH zifanelekile spline, kwaye umsantsa ofanelekileyo mkhulu kakhulu, kunye nomsila weentlobo ezininzi ze-DTH hammerdill bit splines zinokuveza umkhono we-spline ohambelanayo. Ukuba i-debris imanzi, kulula ukwenza isikhwama sodaka kwaye unamathele kwi-dill bit. Ukuba lo mbuso awuphuculwanga ngexesha, isikhwama sodaka siya kungena kwi-gap yokufakela i-spline, eya kuchaphazela ukuhanjiswa okusebenzayo kwamandla empembelelo ye-DTH hammer piston; ngakumbi, intwana ye-dill kunye nomkhono we-spline unokuncamathela kunye.

Ukongezelela, ukuqina kwe-casing yangaphandle ye-hammer ye-DTH nayo yinto ebalulekileyo ethintela ubomi benkonzo yesando se-DTH. Ukuba ukuqina kwayo akulunganga, isando se-DTH siya konakala ngenxa yokungqubana rhoqo nodonga lwequla ngexesha lokomba; xa isando se-DTH singasebenzi, kudla ngokuyimfuneko ukungcangcazela, ukuchithwa kunye nokucoca i-hammer ye-DTH, eya kwandisa umonakalo we-casing yangaphandle ye-hammer ye-DTH. Utshintsho; kunye nokuguqulwa kwe-casing yangaphandle kuya kubangela ukuba iindawo zangaphakathi zesando ze-DTH ziboshwe kwaye azikwazi ukuchithwa, ekugqibeleni ziza kubangela ukuba i-hammer ye-DTH ikhutshwe ngokuthe ngqo.

Xa kusetyenziswa i-cementing fluid, ukunikezelwa kwegesi kuya kumiswa kwakhona, ukwenzela ukuba i-valve yokutshekisha ekupheleni kwesando se-DTH iya kuvalwa ngokukhawuleza.

Nangona kunjalo, ukuba amanzi amaninzi kakhulu angena kumngxuma ongaphakathi wehamile ye-DTH, ezinye iziqendu ziya kuziswa kwi-piston motion pair ye-internal cavity, eyonyusa kakhulu i-frequency ebambekayo yepiston.
Kwangaxeshanye, ukuba i-cuttings efakwe phakathi kwepiston kunye nobuso besiphelo soqhagamshelwano lwe-dill alukwazi ukususwa ixesha elide, ininzi yempembelelo yamandla e-piston iya kuthatyathwa yi-cuttings kwaye ayikwazi ukuhanjiswa ngokufanelekileyo phantsi, oko kukuthi, impembelelo ibuthathaka.
Isizathu 4: Dill Bit Wanamathela
Ibhilidi ye-dill kunye nesando se-DTH zifanelekile spline, kwaye umsantsa ofanelekileyo mkhulu kakhulu, kunye nomsila weentlobo ezininzi ze-DTH hammerdill bit splines zinokuveza umkhono we-spline ohambelanayo. Ukuba i-debris imanzi, kulula ukwenza isikhwama sodaka kwaye unamathele kwi-dill bit. Ukuba lo mbuso awuphuculwanga ngexesha, isikhwama sodaka siya kungena kwi-gap yokufakela i-spline, eya kuchaphazela ukuhanjiswa okusebenzayo kwamandla empembelelo ye-DTH hammer piston; ngakumbi, intwana ye-dill kunye nomkhono we-spline unokuncamathela kunye.
