Saint-Gobain Seals 'OmniSeal spring-energized blowout preventer yakasimbiswa sechisimbiso chakamira muindasitiri yemuchadenga roketi yekutarisa mavharuvhu.
A cheki vharuvhu chinhu chekudzora kuyerera chinongobvumira kudzvanywa mvura (mvura kana gasi) kuyerera munzira imwe. Mukushanda kwakajairika, cheki valve iri munzvimbo yakavharwa apo chisimbiso chinochengetedzwa nechisimbiso chakasimba chakagadzirirwa kutsungirira chero kuputika. Kana imwe nguva mhepo yemvura inosvika kana kudarika iyo yakatemerwa chikumbaridzo, vheji inovhura uye inobvumira mvura kuti iende kubva kune imwe nzvimbo yekumanikidza kusvika kune yakaderera. Kudonhedza kudonha pasi pechikumbaridzo kuchaita kuti valve idzoke panzvimbo yayo yakavharwa. Cheki mavharuvhu zvakare akajairika muindasitiri yemafuta negasi, pamwe nemapombi, kugadzirwa kwemakemikari, uye kushandiswa kwemvura.
Muzviitiko zvakawanda, mainjiniya ekugadzira anozobatanidza mavharuvhu ekutarisa mune yavo roketi injini magadzirirwo. Naizvozvo, basa rezvisimbiso mumikombe iyi rakakosha muhurongwa hwese hwekutanga. Chisimbiso chinopesana nekuputika chinoshandiswa muvhavhavha yecheki kuchengetedza high-pressure fluid padivi repamusoro-soro apo ichidzivirira chisimbiso kubva pakupfira kunze kweimba. Panyaya yekudzvinyirirwa kwepamusoro uye nekukurumidza kudzvanywa kunoshanduka pamusoro pechisimbiso chepamusoro, zvinonetsa kuchengetedza chisimbiso mudzimba dzayo. Kamwe iyo inosimba yekuisa chisimbiso pamusoro peiyo Hardware inobvisa kubva pamuromo wekuvhara, chisimbiso chine tsika yekupeperetswa kubva paimba nekuda kwekumanikidzwa kwakasara kwakatenderedza chisimbiso. Kazhinji, mavharuvhu ekutarisa anoshandisa zvisimbiso zvezvigaro (zvivharo PTFE zviri nyore), asi kushanda kwezvisimbiso izvi hazvienderani, uye nekufamba kwenguva, zvisimbiso zvezvigaro zvichange zvichiremara zvachose, zvichiita kuti pave nekudonha.
Zvisimbiso zveSaint-Gobain Seals 'zvakaputika-zvisimbiso zvakatorwa kubva kune yayo OmniSeal 103A kuvaka uye ine bhachi repolymer rine chitubu chinosimbisa. Iyo goko rekunze rakagadzirwa neyemuridzi Fluoroloy zvinhu, nepo chitubu chakagadzirwa nesimbi isina tsvina uye Elgiloy® zvinhu. Maererano nemamiriro ekushanda kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhava,muitiro unokosha unogona kushandiswa kupisa nekuchenesa chitubu. Mufananidzo uri kuruboshwe unoratidza muenzaniso wezvakajairwa zvinodzivirira zvinoputika zvinoshandiswa neSaint-Gobain zvisimbiso mukushandiswa kwetsvimbo yekuisa chisimbiso (chinyorwa: mufananidzo uyu wakasiyana nechisimbiso chaicho chinoshandiswa mucheki chevhavha yekushandisa, iyo yakasarudzika-yakagadzirwa). Zvisimbiso mucheki mavharuvhu maapplication anogona kushanda patembiricha yakaderera kusvika ku575 ° F (302 ° C) uye anogona kumira kumanikidzwa kusvika ku6,000 psi (414 bar).
Chinangwa cheOmniSeal kuputika-chisimbiso chezvisimbiso zveroketi injini cheki mavharuvhu ndechekusunga gasi rakamanikidzwa uye gasi rakanyungudutswa patembiricha iri pasi -300°F (-184°C) kusvika 122°F (50°C). Kumanikidzwa kwechisimbiso kuri pedyo ne3,000 psi (207 bar). Fluoroloy® sheath material ine yakanakisa kupfeka kuramba, deformation kuramba, yakaderera friction coefficient uye yakanyanya kuderera tembiricha kuita. OmniSeal® anti-leak zvisimbiso zvakagadzirirwa kuita mazana ematenderera ekushanda pasina kuvuza.
Iyo OmniSeal® chigadzirwa mutsetse ine akasiyana magadzirirwo, akadai se103A, APS, Spring Ring II, 400A, RP II uye RACO™ 1100A, pamwe neakasiyana dhizaini. Aya madhizaini anosanganisira akasiyana fluorine zvinhu zvekuisa chisimbiso maoko uye akasiyana masisitimu ezvitubu. MaSaint-Gobain Seals 'sealing solutions akashandiswa mukutanga mota dzakaita seAtlas V rocket engines (kutangisa Mars Rover Curiosity muchadenga), Delta IV Heavy roketi neFalcon 9 maroketi. Mhinduro dzavo dzinoshandiswawo mune mamwe maindasitiri (oiri negesi, mota, sainzi yehupenyu, zvemagetsi neindasitiri), pamwe neyakatenderedza maindasitiri ekudhaya machira emidziyo, pombi jekiseni remakemikari, imwe yenyika yekutanga pasi pesea gasi compression zviteshi uye makemikari analyzers. kushandiswa kwekirasi. .
