Tinovaka masisitimu edu emvura yehelium ne liquid nitrogen shield kuti tidzivise kudonha kwekupisa kubva patembiricha yemukamuri kusvika pamutsetse we helium we 4 K. Chidziviriro ichi chiri pa77 K, chichishanda se thermal buffer; chinotora kupisa kwakawanda kwe radiative uye conductive isati yasvika ku helium. Pa HL Cryogenics, nzira iyi inowedzera kushanda zvakanaka kwesimba, inochengetedza helium kuti isafashaire nekukurumidza, uye inobatsira mitsetse mirefu yekufambisa kufamba zvakanaka uye yakavimbika. Uchawana LN₂ shield iri mukati meduPipe yeVacuum Insulatedgadziriro, yakakomberedzwa nechinhu chinonyungudutsa mvura chakachengetedzwa zvakanaka.
Munzvimbo huru dzinoita kuti mhepo itsvuke, kusvetuka chidziviriro ichi chepakati hachisi sarudzo chaiyo. Pasina icho, kupisa kubva mumwaranzi negasi rinobuda mukati me vacuum barrier zvaizokunda helium circuit, zvichikonzera kupwanyika nekukurumidza uye zvichiita kuti kushanda kwakasimba kuve kusingabviri.
Dhizaini yedu inotarisa pamhando huru dzekutamisa kupisa—mwaranzi, kupinza mhepo, uye kupinza gasi zvishoma. Vacuum inobvisa convection, asi mwaranzi ichiri kusundira kupisa kunzvimbo dzinotonhora zvikuru. Ndipo panopinda nitrogen shield. Pa77 K, inotora simba rakawanda iri, saka chikamu chidiki chete chinopinda muhelium. Kune mapaipi ane vacuum-jacketed high-performance—kunyanya mumasystem anorema ekufambisa cryogenic—iyi nitrogen shield haingobatsiri chete; chikamu chakakosha cheinjiniya. Ndiyo inoita kuti system igare yakasimba, inoshanda, uye isingadhuri munguva yayo yese yekushanda.

●Kugadzirwa kwesystem uye kubatanidzwa kwayo nezvigadzirwa zveHL Cryogenics
Zvisinei, mumabasa edu einjiniya, LN2 Shield pachayo haisi chinhu chinongomira chega asi isystem iri pasi pesystem yese ye cryogenic pipeline. Kazhinji, subsystem iyi inoshandiswa pamwe chete ne ...Pipe yeVacuum Insulated, Vacuum Insulated Flexible Hose, uyeVharuvhu Yakaputirwa neVacuummasisitimu ekugadzira sisitimu yakazara yekudzora tembiricha. Zvichienderana nekirasi yepurojekiti uye zvinodiwa pakumanikidzwa kwayo, denderedzwa rechidzitiro rinogona kurongwa zvakaenzana kana kuti zvakavharika.
Kana kushandiswa kwenguva refu kana kuti kwenguva refu,Sisitimu yeDynamic Vacuum PombiInoshandiswa kuona kuti vacuum iri mukati memapombi inogara kwenguva refu. Izvi zvichaita kuti hunhu hwekudzivirira kupisa hwepaipi husakanganiswe nekuda kwekubuda kwemvura kana kubuda kwegasi nekufamba kwenguva. Kushandisa LN2 shielding uye kupomba vacuum nguva dzose kunoita kuti pave nekupisa kushoma uye kusingashande zvakanaka.
●Kushanda kwekupisa uye maitiro ekudzivirira vacuum
Nekubatanidza yeduSisitimu yeDynamic Vacuum Pombi, Vharuvhu Yakaputirwa neVacuumuyeMusiyanisi weDanho, tinokupai nzira inokwanisa kufambisa helium yemvura zvinobudirira uye inochengetedza mitengo yakaderera.Tangi dikis uyeMapombi Anochinjikangatiite mabasa ese ari maviri ekufambisa neakagadzirwa nemazvo.
Kubva pamaonero einjiniya, kushanda zvakanaka kwechidzitiro chakavakirwa panitrogen yemvura kunoenderana ne vacuum cleaner, emisisivity yezvinhu, uye dhizaini yekupisa inosimbisa. Vacuum iri mukati memidziyo yedu yeHL Cryogenics yakagadzirirwa kushanda munzvimbo dziri pakati pe10⁻³ - 10⁻⁶ Pa. Pakumanikidzwa kwakadaro, kufambiswa kwegasi kunogona kuregeredzwa, uye mwaranzi ndiyo nzira huru yekufambisa kupisa.
Kana uchishandisa jira re nitrogen cooled shield, kushanda zvakanaka kwekupisa kunoderera kusvika pa70-90% kana tichienzanisa ne single vacuum insulation. Izvi zvinoita kuti pave nekushanda kuri nani kwePipe yeVacuum Insulateduye kudzikira kwekufashaira kwemvura kana paine masisitimu ehelium. Munzvimbo dzakakura, kunyangwe kuwedzera kudiki kwekuderera kwekubuda kwemvura mukupisa kunotungamira mukuchengetedza mari yakawanda nekuda kwemutengo wepamusoro wehelium.
Kusarudzwa kwezvinhu zvakakoshawo. Tinoshandisa simbi isingatsvi (304L ne316L dzinonyanya kufarirwa), nekuda kwekusapisa kwayo uye simba rayo pakupisa kwe cryogenic uye kugona kwayo kusangana nezvinodiwa zve welding. Zvese zvatiri kuisa zvinoenderana neASME, CE, uye ISO standards ye pressure vessels uye cryogenic engineering.
●Basa rekutsigira masisitimu e cryogenic
Nhumbi yenitrogen haishande zvakanaka pasina seti yema subsystems e cryogenic. Nerubatsiro rwemhuri yedu yeHL Cryogenics yezvigadzirwa, chimwe chezvishandiso zvatakagadzira chinonziChinoparadzanisa Chikamu Chinoputirwa neVacuum.Zvakakosha kuti mvura igare yakasimba uye kuti idzivirire kubva pakuvharwa kwemvura mumitsetse yekugovera.
Uyezve, dhizaini yeVharuvhu Yakaputirwa neVacuumChinangwa ndechekupa mabhiriji ekupisa akaderera sezvinobvira ukuwo uchichengetedza kurongeka kwekuyerera kwemvura pakusiyana kwekupisa kwakanyanya. Kushandiswa kwemidziyo yakadaro kunonyanya kukosha mu liquid nitrogen system nemapaipi e liquid helium system ane mitoro yakasiyana-siyana.
Chimwe chishandiso chinowanzoiswa muma network e cryogenic ane huwandu hwakawanda ndecheTangi dikipamwe chete nehurongwa hwedu.Sisitimu yeDynamic Vacuum Pombi, zvinopa kuenzana pakati pekumanikidzwa, tembiricha, uye kugoverwa kwezvikamu.
Mamiriro ekushandisa mainjiniya chaiwo
Mune imwe purojekiti yeLNG kuSoutheast Asia, taifanira kutamisa helium yemvura nedaro refu—uye kuchengetedza kurasikirwa kwekupisa kwakaderera kwaikosha. Sarudzo dzekudzoreredza helium dzaive shoma, saka kurasikirwa nezvinhu zvishoma kwaireva kutambisa mari. Kuti tigadzirise izvi, takavaka sisitimu yekudzivirira kupisa ine zvikamu zviviri: takashandisaPipe yeVacuum Insulateduye yakawedzera denderedzwa rekudzivirira nitrogen yemvura.
Mamiriro ekunze ekuSoutheast Asia haana kunaka kune vanhu vane kenza. Tembiricha dzaiwanzokwira pamusoro pe35°C, uye hunyoro hwacho hwaive hwakanyanya, asi hurongwa hwacho hwakaramba hwakanaka. Pakangotanga kushanda, takaona kudzikira kukuru kwehelium boil-off zvichienzaniswa nezvataitarisira pasina chidziviriro chenitrogen.Sisitimu yeDynamic Vacuum Pombiyakaita basa rayo—huwandu hwevacuum hwairamba hwakagadzikana panguva yekushanda pasina kumira. Pose patakada kugadzirisa, maVacuum Insulated Valves akaita shuwa kuti taigona kuparadzanisa zvikamu zvepombi zvakachengeteka.
Tichiona nhamba dzacho, zviri pachena: multi-stage thermal interception haisi dzidziso chete. Munzvimbo dzakadai seLNG terminals ne semiconductor plants, zvakakosha. Kugadzikana kwemaitiro hakusi sidebar—zvinotsanangura kuti nzvimbo idzi dzinogona kushanda zvakanaka sei.
KuHL Cryogenics, tinogadzira masisitimu ekudzivirira nitrogen yemvura anoita basa rakakosha muinjiniya yemazuva ano yecryogenic—kunyanya kana zvasvika pakugadzirisa helium yemvura uko kuchengetedza zvinhu zvakagadzikana pakupisa kunonyanya kukosha. Tinoisa vacuum insulation yepamusoro, zvikamu zvakagadzirwa nemazvo, uye tinotevedzera mitemo yakasimba yekugadzira, saka masisitimu edu anoshanda zvakavimbika kumapurojekiti egasi remaindasitiri pasi rese.
Tinogara tichigadzirisa mapaipi edu anoputira vacuum insulation, mapombi anochinjika, uye tichitsigira ma subsystem e cryogenic kuti akwanise kubata mabasa akaoma muzvivakwa zveLNG, kugadzira ma semiconductor, uye mapurojekiti esimba rehydrogen muEurope, Asia, neMiddle East.
Kana muchida mhinduro ye cryogenic yakagadzirirwa purojekiti yenyu, kana kuti muchida kutaura nezvekugadzira sisitimu, takasununguka kutaurirana nehunyanzvi nemakambani eEPC, mainjiniya, nemapoka ekutenga.
●Mibvunzo Inowanzo bvunzwa
Kubva muna 1992, HL Cryogenics yave nyanzvi mukugadzira nekugadzira masisitimu emapaipi e cryogenic ane vacuum yakawanda uye michina yekutsigira yakafanana, yakagadzirirwa kusangana nezvinodiwa nevatengi vakasiyana-siyana. Tine zvitupa zveASME, CE, uye ISO 9001, uye takapa zvigadzirwa nemasevhisi kumakambani mazhinji anozivikanwa epasi rose. Chikwata chedu chakavimbika, chine mutoro, uye chakazvipira kuita basa rakanaka mupurojekiti yega yega yatinoita.
