A cryogenic gedhi vharuvhu ine bhoneti yakatambanudzwa yakagadzirirwa kushanda patembiricha yakaderera se -196 ° C inowanzovakwa kuti imirire kutonhora kwakanyanya uye kuchengetedza kushanda kwakakodzera mumamiriro ezvinhu akaoma kudaro. Aya mavharuvhu anowanzo shandiswa mumaindasitiri akadai se liquefied natural gas (LNG) processing, industry gas production, and other cryogenic applications apo kunyanyodzikira tembiricha kunobatanidzwa.The extended bonnet design rinopa kumwe kuvharirwa uye kudzivirira kwevharuvhu hunde uye kurongedza, kudzivirira iwo. kubva mukutonhorwa nechando kana kuita brittle pakudziya kwakaderera kudaro. Pamusoro pezvo, zvinhu zvinoshandiswa pakuvaka vharuvhu, senge alloys akasarudzika kana epasi-tembiricha mapurasitiki, anosarudzwa kuchengetedza simba ravo uye kuvimbika munzvimbo dze cryogenic. Mavharuvhu akadaro akakosha pakudzora zvakachengeteka kuyerera kweiyo cryogenic fluid uye magasi, uye vanopinda mukuyedzwa kwakasimba kuti vaone kuti vanogona kubata tembiricha yakanyanyisa uye kumanikidza kunosanganisirwa.
1.Chimiro chiri nyore kudarika gedhi revhavha, uye zviri nyore kugadzira nekuchengetedza.
2.Chisimbiso chekuisa chisimbiso hachisi nyore kupfeka uye kukwenya, uye kuiswa chisimbiso kwakanaka. Iko hakuna hama inotsvedza pakati pevharuvhu disc uye chisimbiso pamusoro pemuviri wevharuvhu pakuvhura nekuvhara, saka kupfeka nekukwenya hakuna kukomba, kuita chisimbiso kwakanaka, uye hupenyu hwesevhisi hurefu.
3.Paunenge uchizarura nekuvhara, kurova kwe diski kuduku, saka kureba kwevhavha yekumisa kuduku kudarika yevhavha yegedhi, asi urefu hwekugadzirisa hurefu kupfuura iyo yevhavha yegedhi.
4.Kuzarura nekuvhara torque yakakura, kuzarura nekuvhara kwakaoma, uye nguva yekuzarura nekuvhara yakareba.
5.Kupikisa kwemvura yakakura, nokuti nzira yepakati mukati memuviri wevhavha inotambudza, kupikisa kwemvura yakakura, uye kushandiswa kwesimba kwakakura.
6.Medium kuyerera kwekutungamira Kana iyo zita rekumanikidza PN ≤ 16MPa, inowanzotora kuyerera kwemberi, uye yepakati inoyerera ichikwira kumusoro kubva pasi pevhavha disc; apo iyo nominal pressure PN ≥ 20MPa, kazhinji inotora counter flow, uye yepakati inoyerera ichidzika kubva kumusoro kwevhavha disc. Kuwedzera kushanda kwechisimbiso. Kana ichishandiswa, svikiro repasi rose rinogona kungoyerera munzira imwe chete, uye nzira yekuyerera haigone kuchinjwa.
7.Iyo disc inowanzosvibiswa kana yakazaruka zvakakwana.
Munguva yekuvhura nekuvhara nzira yesimbi yakaumbwa yeglobe valve, nekuti kukweshera pakati pe disc uye yekuvharisa pamusoro pemuviri wevharuvhu idiki pane iyo yevhavha yegedhi, haibatike.
Kuvhura kana kuvhara kwevhavha hunde ipfupi, uye ine yakavimbika kwazvo yekucheka-kubvisa basa, uye nekuti shanduko yevhavha chigaro chechiteshi inoenderana nekurohwa kwevhavha disc, yakakodzera kwazvo kugadzirisa. yehuwandu hwekuyerera. Naizvozvo, rudzi urwu rwevharuvhu rwakanyatsokodzera kucheka-kubvisa kana kudzora uye throttling.

Senyanzvi yekugadzira mavharuvhu esimbi uye mutengesi kunze, tinovimbisa kupa vatengi nemhando yepamusoro-soro mushure mekutengesa sevhisi, kusanganisira zvinotevera:
1.Kupa mazano ekushandiswa kwechigadzirwa uye mazano ekugadzirisa.
2.Nekukundikana kunokonzerwa nezvinetso zvehutano hwechigadzirwa, tinovimbisa kupa rubatsiro rwehutano uye kugadzirisa matambudziko mukati menguva pfupi.
3.Kunze kwekukuvadza kunokonzerwa nekushandiswa kwakajairika, tinopa mahara kugadzirisa uye kutsiva masevhisi.
4.Tinovimbisa kupindura nekukurumidza kune zvinodiwa nevatengi panguva yechigadzirwa waranti nguva.
5. Isu tinopa tsigiro yenguva refu yehunyanzvi, kubvunzana pamhepo uye masevhisi ekudzidzisa. Chinangwa chedu ndechekupa vatengi ruzivo rwesevhisi yakanakisa uye kuita kuti ruzivo rwevatengi ruwedzere kunakidza uye nyore.
