OmniSeal kubva kuSaint-Gobain Seals inotenderwa kuti ishandiswe sezvisimbiso zvemaroketi injini

Iyo OmniSeal chitubu-chakasimba kuputika-chisimbiso chisimbiso cheSaint-Gobain Seals chakaonekwa sechisimbiso chakamira mune roketi injini yekutarisa valve yeindasitiri yezvemuchadenga. 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 ne static zvisimbiso zvakagadzirirwa 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 yepamusoro kusvika kune yakaderera. Kudonhedza kudonha pasi pechikumbaridzo kuchaita kuti valve idzoke panzvimbo yayo yakavharwa. Cheki mavharuvhu zvakare akajairika muindasitiri yemafuta negesi, pamwe nemapombi, kugadzirwa kwemakemikari, uye kushandiswa kwemvura. Muzviitiko zvakawanda, mainjiniya ekugadzira anobatanidza mavharuvhu ekutarisa mune yavo roketi injini magadzirirwo. Naizvozvo, basa rezvisimbiso mumipata iyi rakakosha zvikuru muhurongwa hwese hwekutanga. Chisimbiso chekudzivirira chinoputika chinoshandiswa muvhavhavhavhavhavha kuitira kuchengetedza mvura yakamanikidzwa padivi repamusoro-soro apo ichidzivirira chisimbiso kubva pakupfira kunze kweimba. Pasi pekudzvinyirirwa kwepamusoro uye nekukurumidza kuchinja kwekuisa chisimbiso pamusoro pekumanikidza, zvakanyanya kuoma kuchengetedza chisimbiso mudzimba dzayo. Kamwe iyo inosimba yekuisa chisimbiso pamusoro peiyo hardware yakaparadzaniswa kubva pamuromo wekuvhara, chisimbiso chinogona kupeperetswa kubva paimba nekuda kwekumanikidzwa kwakasara kwakatenderedza chisimbiso. Kazhinji zvisimbiso zvezvigaro, zvidhinha zvePTFE zviri nyore, zvinoshandiswa pakuongorora mavharuvhu, asi kushanda kwezvisimbiso izvi hazvienderani. Nekufamba kwenguva, zvisimbiso zvechigaro zvichange zvave kuremara zvachose, zvichikonzera kuvuza. Zvisimbiso zveSaint-Gobain Seals 'zvinoputika-zvisimbiso zvinotorwa kubva kune yayo OmniSeal 103A kumisikidzwa uye ine polymer bhachi ine chitubu chinosimbisa. Iyo sheath inogadzirwa neyemuridzi Fluoroloy zvinhu, nepo chitubu chinogona kugadzirwa nezvinhu zvakaita sesimbi isina tsvina uye Elgiloy®. Maererano nemamiriro ekushanda evhavhavhavhavhavha, chitubu chinogona kupisa kupisa uye kucheneswa nemaitiro anokosha. Mufananidzo uri kuruboshwe unoratidza muenzaniso wezvisimbiso zvinorwisa-kuvhuvhuta kune general Saint-Gobain seals mu rod seal applications (chinyorwa ichi: mufananidzo uyu wakasiyana nezvisimbiso zvakashandiswa mucheki mavharuvhu ekushandisa, ayo akajairwa-akagadzirwa). Tarisa mavharuvhu mashandisirwo Zvisimbiso mukati zvinogona kushanda munzvimbo yakaderera tembiricha kusvika 575 ° F (302 ° C) uye inogona kumira kumanikidzwa kusvika ku6,000 psi (414 bar). The OmniSeal explosion-proof chisimbiso chinoshandiswa mu rocket engine cheki mavharuvhu chinoshandiswa kunama gasi rakadzvanywa uye gasi rakanyungudutswa mutembiricha iri pazasi -300°F (-184°C) kusvika 122°F (50°C). Chisimbiso chinogona kumira kumanikidzwa pedyo ne3,000 psi (207 bar). Fluoroloy® sheath material ine yakanakisa kupfeka kuramba, deformation kuramba, yakaderera friction coefficient uye yakanyanya kutonhora tembiricha kugona. OmniSeal® Blowout Prevention Seals yakagadzirirwa kumhanyisa mazana ematenderedzwa pasina kuvuza. Iyo OmniSeal® chigadzirwa mutsara inopa akasiyana madhizaini, akadai se103A, APS, Spring Ring II, 400A, RP II uye RACO™ 1100A, pamwe neakasiyana etsika magadzirirwo. Aya madhizaini anosanganisira yekuisa chisimbiso maoko eakasiyana fluorine alloy zvinhu uye zvitubu zveakasiyana masisitimu. MaSaint-Gobain Seals 'sealing solutions akashandiswa mukuvhura mota senge Atlas V rocket engine (kutumira Curiosity Mars rover muchadenga), Delta IV heavy rocket neFalcon 9 rocket. Mhinduro dzavo dzinoshandiswawo mune mamwe maindasitiri (oiri negasi, mota, sainzi yehupenyu, zvemagetsi neindasitiri) uye zvakatipoteredza zvine hushamwari maindasitiri ekudhaya magadzirirwo emidziyo, majekiseni emakemikari pombi, yekutanga pasi pesea gasi compression station uye kemikari analyzers, nezvimwewo.
