Ukuguga kombhobho yijethi ye-hydraulic sandblasting ikakhulukazi ukuguguleka kwezinhlayiya zesihlabathi odongeni lwangaphakathi lombhobho. Ukugqoka kwe-nozzle kuwumphumela wesenzo sejethi yesihlabathi odongeni lwangaphakathi lombhobho. Ngokuvamile kukholakala ukuthi ukulahleka kwevolumu ye-macroscopic yendawo engaphakathi yomlomo womlomo ngenxa yokuguga kwakhiwe ukunqwabelana kokulahlekelwa kwevolumu ye-microscopic okubangelwa umthelela wezinhlayiyana zesihlabathi esisodwa. Ukuguguleka kwesihlabathi endaweni engaphakathi yomlomo ikakhulukazi kufaka phakathi izinhlobo ezintathu: ukuguga okuncane, ukukhathala kanye nokuqhekeka okuphukayo. Nakuba izinhlobo ezintathu zokugqoka zenzeka ngesikhathi esisodwa, ngenxa yezimpawu ezihlukene zempahla ye-nozzle kanye nezici zezinhlayiya zesihlabathi, isimo sokucindezeleka ngemva komthelela sihlukile, futhi ingxenye yamafomu amathathu okugqoka ihlukile.

1. Izinto ezithinta ukugqokwa kwemibhobho

1.1 Izinto ezibonakalayo zenozi ngokwayo

Njengamanje, izinto ezivame ukusetshenziselwa ukwenza ama-jet nozzles ikakhulukazi yinsimbi yamathuluzi, izitsha zobumba, i-carbide enosimende, amagugu okwenziwa, idayimane nokunye. Imicro-structure, ubulukhuni, ukuqina kanye nezinye izakhiwo ezingokomzimba nezemishini yezinto ezibonakalayo zinemiphumela ebalulekile ekuphikisweni kwayo kokugqoka.

1.2 Umumo wesakhiwo seshaneli yokugeleza kwangaphakathi namapharamitha wejometri.

Ngokulingisa izinhlobo ezahlukene zemibhobho, umbhali wathola ukuthi ku-hydraulic sandblasting jet system, i-nozzle eguquguqukayo eguquguqukayo ingcono kune-nozzle ehlanjululwayo, i-nozzle elula ingcono kune-conical nozzle, futhi i-conical nozzle ingcono kune-nozzle. umlomo wombhobho. Ububanzi bokukhipha umlomo wombhobho ngokuvamile bunqunywa izinga lokugeleza nokucindezela kwendiza. Uma izinga lokugeleza lingashintshiwe, uma ububanzi bokuphuma buncishisiwe, ukucindezela kanye nezinga lokugeleza kuzoba kukhudlwana, okuzokwandisa umthelela wamandla we-kinetic wezinhlayiya zesihlabathi futhi kwandise ukuguga kwesigaba sokuphuma. Ukwandisa ububanzi be-jet nozzle kuzophinde kwandise ukuguga okukhulu, kodwa ngalesi sikhathi ukulahlekelwa kwendawo yangaphakathi kuncishisiwe, ngakho-ke kufanele kukhethwe ububanzi be-nozzle engcono kakhulu. Imiphumela itholakala ngokulingiswa kwezinombolo kwenkambu yokugeleza kwe-nozzle enama-engeli ahlukene wokufinyeza.

Ukufingqa, fnoma i-conical nozzle, i-Angle yokufinyela incane, ukugeleza kuzinzile, ukuhlakazeka okuncane, kanye nokuguga okuncane ku-nozzle. Ingxenye ye-cylindrical eqondile ye-nozzle idlala indima yokulungiswa, futhi isilinganiso saso sobude bobubanzi sibhekisela esilinganisweni sobude besigaba se-cylinder ye-nozzle kuya kububanzi bokukhipha, okuyipharamitha ebalulekile ethinta ukugqokwa. Ukwandisa ubude be-nozzle kunganciphisa izinga lokugqoka le-outlet, ngoba indlela yokugqoka ijika eya ekuphumeni inwetshiwe. Indawo yokungenaaI-ngle ye-nozzle inomthelela oqondile ekugqokeni kwephaseji lokugeleza kwangaphakathi. Lapho ukufinyela kwe-inletai-ngle iyancipha, izinga lokugqoka kwe-outlet liyancipha ngokulandelana.

1.3 Ubuqhwaga bangaphakathi

Ingaphezulu le-micro-convex lodonga lwangaphakathi lombhobho likhiqiza ukumelana okukhulu nejethi eqhuma isihlabathi. Umthelela wezinhlayiya zesihlabathi engxenyeni egqagqene yesiqhumane ubangela ukunwebeka kwe-micro-crack engaphezulu futhi kusheshise ukuguga okuhuzuka kombhobho. Ngakho-ke, ukunciphisa ukuqina kodonga lwangaphakathi kusiza ukunciphisa ukungqubuzana.

1.4 Umthelela wokuqhunyiswa kwesihlabathi

Isihlabathi se-quartz kanye ne-garnet kuvame ukusetshenziswa ku-hydraulic sandblasting fracturing. Ukuguguleka kwesihlabathi ezintweni ze-nozzle kuyimbangela eyinhloko yokugqoka, ngakho-ke uhlobo, ukuma, usayizi wezinhlayiya kanye nokuqina kwesihlabathi kunethonya elikhulu ekugqokeni kwe-nozzle.
