Nekuvandudzwa kwesimba rekutakura roketi ye cryogenic, kudiwa kwehuwandu hwemafuta anozadza propellant kuri kuwedzerawo. Pombi inotakura mvura ye cryogenic fluid chishandiso chakakosha mumunda wemuchadenga, chinoshandiswa mu cryogenic propellant filling system. Mupombi inotakura mvura ye cryogenic fluid ine tembiricha yakaderera, pombi ye vacuum ine tembiricha yakaderera, nekuda kwekuvhara kwayo zvakanaka, kuramba kumanikidzwa uye kushanda kwayo kwakakombama, inogona kutsiva nekudzora shanduko yekutama inokonzerwa nekuwedzera kwekupisa kana kudzikira kwechando kunokonzerwa nekuchinja kwetembiricha, kutsiva kutsauka kwekuisa kwepombi uye kuderedza kudedera neruzha, uye kuva chinhu chakakosha chinotakura mvura muhurongwa hwekuzadza hwe tembiricha yakaderera. Kuti ienderane nekuchinja kwenzvimbo kunokonzerwa nekufamba kwedhoki nekudonha kwechombo chekuzadza che propellant munzvimbo diki yeshongwe inodzivirira, pombi yakagadzirwa inofanira kunge iine mukana unochinjika mumativi ese ari maviri akachinjika uye erefu.

Hosipu itsva ye cryogenic vacuum inowedzera dhayamita yekugadzira, inovandudza kugona kwekutamisa mvura ye cryogenic, uye inochinjika nyore nyore munzira dzese dziri kurutivi nedzekureba.

Dhizaini yechimiro chose chehose ye cryogenic vacuum

Zvichienderana nezvinodiwa zvekushandiswa uye nzvimbo yekupfapfaidza munyu, simbi 06Cr19Ni10 inosarudzwa sechinhu chikuru chepombi. Kuungana kwepombi kune zvikamu zviviri zvemapombi, muviri wemukati nemuviri wekunze, zvakabatana negokora re90° pakati. Foil yealuminium nejira risiri realkali zvinoputirwa zvakasiyana pamusoro pekunze kwemuviri wemukati kuti zvigadzire insulation layer. Mhete dzakawanda dzePTFE dzinotsigira hosipaipi dzinoiswa kunze kweinsulation layer kudzivirira kusangana zvakananga pakati pemapombi emukati nekunze uye kuvandudza mashandiro einsulation. Migumo miviri yejoini zvinoenderana nezvinodiwa zvekubatanidza, dhizaini yechimiro chinoenderana chejoini re adiabatic rakakura. Bhokisi re adsorption rakazadzwa ne 5A molecular sieve rakarongwa mu sandwich yakagadzirwa pakati pezvikamu zviviri zvemachubhu kuti ive nechokwadi chekuti pombi ine vacuum degree yakanaka uye hupenyu hwe vacuum pa cryogenic. Puragi yekuvharira inoshandiswa kune sandwich vacuuming process interface.

Zvinhu zvinodzivirira kuputira

Chidzitiro chekudzikisa ganda chine zvikamu zvakawanda zvechidzitiro chekuratidzira uye chikamu chepakati chinomonereka pamadziro eadiabatic. Basa guru rechidzitiro chekuratidzira nderekuparadzanisa kutamiswa kwekupisa kwemwaranzi yekunze. Chidzitiro chinogona kudzivirira kusangana zvakananga nechidzitiro chekuratidzira uye kushanda sechinodzivirira moto uye sekudzivirira kupisa. Zvinhu zvechidzitiro zvinoratidzira zvinosanganisira aluminium foil, aluminized polyester film, nezvimwewo, uye zvinhu zvechikamu chepakati zvinosanganisira bepa regirazi refiber risiri realkali, jira regirazi refiber risiri realkali, jira renylon, bepa readiabatic, nezvimwewo.

Muchirongwa chekugadzira, jira realuminium rinosarudzwa sechikamu chekudzivirira kupisa sechidzitiro chinoratidza chiedza, uye jira regirazi risingashandisi alkali sechikamu chepakati.

Bhokisi reAdsorbent uye adsorption

Adsorbent chinhu chine magadzirirwo ema microporous, nzvimbo yacho yakakura yekudzvora mvura, nekuda kwesimba remamorekuru ekukwevera mamorekuru egasi pamusoro peadsorbent. Adsorbent iri musandwich ye cryogenic pipe inoita basa rakakosha mukuwana nekuchengetedza dhigirii re vacuum yesandwich pa cryogenic. Adsorbents dzinowanzoshandiswa i5A molecular sieve uye active carbon. Pasi pemamiriro e vacuum uye cryogenic, 5A molecular sieve uye active carbon zvine simba rakafanana re adsorption reN2, O2, Ar2, H2 nemamwe magasi akajairika. Activated carbon iri nyore kubvisa mvura kana ichidzvora mvura musandwich, asi iri nyore kupisa muO2. Activated carbon haisarudzwe se adsorbent ye liquid oxygen medium pipeline.
