Nekuvandudzwa kwesimba rekutakura re cryogenic rocket, chinodiwa chepropellant kuzadza kuyerera kuri kuwedzera zvakare.Cryogenic fluid inotakura pombi chinhu chakakosha mundima yeaerospace, iyo inoshandiswa mu cryogenic propellant kuzadza system.Mupombi inoyerera yakadzika-tembiricha, iyo yakadzika-tembiricha vacuum hose, nekuda kwekuvharika kwayo kwakanaka, kudzvanya kurwisa uye kukotama kuita, inogona kubhadhara uye kutora shanduko yekutamisa inokonzerwa nekuwedzera kwekupisa kana kutonhora kunokonzerwa nekushanduka kwekushisa, kuripa kuisirwa. kutsauka kwepombi uye kuderedza vibrate uye ruzha, uye kuva chinhu chakakosha chemvura inofambisa chinhu mune yakaderera-tembiricha yekuzadza system.Kuti uenderane nekuchinja kwechinzvimbo kunokonzerwa nekuita docking uye kudurura kweiyo propellant yekuzadza chinongedzo munzvimbo diki yeshongwe yekudzivirira, iyo pombi yakagadzirwa inofanirwa kuve nekumwe kuchinjika kuchinjika mune zvese zvakachinjika uye kureba nzira.

Iyo nyowani cryogenic vacuum hose inowedzera dhizaini yedhizaini, inovandudza iyo cryogenic fluid kutamisa kugona, uye ine inochinjika inochinjika mune ese ari maviri lateral uye longitudinal nzira.

Yakazara chimiro dhizaini ye cryogenic vacuum hose

Zvinoenderana nezvinodiwa zvekushandisa uye nzvimbo yekupfapfaidza munyu, iyo simbi zvinhu 06Cr19Ni10 inosarudzwa sechinhu chikuru chepombi.Kuungana kwepombi kunosanganisira zvikamu zviviri zvemuviri wepombi, muviri wemukati uye wekunze network network, yakabatanidzwa ne 90 ° gokora pakati.Aluminium foil uye jira risiri-alkali rakakuvadzwa pane imwe kunze kwemuviri wemukati kuti ivake iyo insulation layer.Nhamba dzinoverengeka dzePTFE hose dzinotsigira mhete dzakaiswa kunze kwechivharo chekudzivirira kudzivirira kusangana kwakananga pakati pepombi dzemukati nekunze uye kuvandudza mashandiro ekudzivirira.Migumo miviri yejoini zvinoenderana nezvinodiwa zvekubatanidza, dhizaini yekufananidza chimiro cheiyo hombe dhayamita adiabatic joint.Bhokisi readsorption rakazadzwa ne5A molecular sieve rakarongwa musangweji yakaumbwa pakati pezvikamu zviviri zvemachubhu kuti ive nechokwadi chekuti pombi ine dhigirii rekutsvaira uye hupenyu hwekutsvaira pa cryogenic.Iyo yekuisa chisimbiso plug inoshandiswa kune sandwich vacuuming process interface.

Insulating layer material

Iyo insulation layer inoumbwa neakawanda akaturikidzana ekuratidzira skrini uye spacer layer inochinjika ronda pamadziro eadiabatic.Basa guru rereflector screen ndeyekuparadzanisa kunze kwemwaranzi kupisa kupisa.Iyo spacer inogona kudzivirira yakanangana neiyo inoratidzira skrini uye kuita senge inodzoreredza murazvo uye kupisa kupisa.Izvo zvinoratidzira skrini zvinhu zvinosanganisira aluminium foil, aluminized polyester firimu, nezvimwewo, uye spacer layer zvinhu zvinosanganisira isiri-alkali girazi fiber bepa, isiri-alkali girazi fiber jira, jira renaironi, adiabatic bepa, nezvimwe.

Muchirongwa chekugadzira, aluminium foil inosarudzwa seyakagadzika sevhavha inotaridza skrini, uye isiri-alkali girazi fiber jira se spacer layer.

Adsorbent uye adsorption bhokisi

Adsorbent chinhu chine microporous chimiro, chikamu chayo misa adsorption nzvimbo yakakura, nemamorekuru simba kukwezva magasi mamorekuru pamusoro peiyo adsorbent.Iyo adsorbent mu sandwich ye cryogenic pipe inoita basa rakakosha mukuwana nekuchengetedza dhigirii rekutsvaira sandwich pa cryogenic.Iwo anowanzo shandiswa adsorbents ndeye 5A molecular sieve uye inoshanda kabhoni.Pasi pevacuum uye cryogenic mamiriro, 5A molecular sieve uye inoshanda kabhoni ine yakafanana adsorption kugona kweN2, O2, Ar2, H2 uye mamwe magasi akajairika.Activated kabhoni iri nyore kunyudza mvura kana uchitsvaira musandwich, asi iri nyore kupisa muO2.Activated carbon haina kusarudzwa se adsorbent ye liquid oxygen yepakati pombi.

5A molecular sieve yakasarudzwa sesandwich adsorbent muchirongwa chekugadzira.
