GB5310, GB6479, GB9948matatu marudzi epaipi yakajairika simbi, kuwedzera kune iyo fluid yekufambisa chubhu inofanirwa kuongororwa, asi zvakare inodiwa kuita flaring bvunzo uye kukanganisa bvunzo; Izvo zvinodiwa zvekuongorora zvekugadzira zvemhando nhatu idzi dzepombi dzesimbi dzakasimba.
GB6479standard inoitawo zvakakosha zvinodiwa kune yakaderera tembiricha kukanganisa kuoma kwezvinhu.
GB3087 yakajairika simbi pombi, mukuwedzera kune zvakajairika bvunzo zvinodiwa kune fluid yekufambisa simbi pombi, asi zvakare inoda kutonhora kukotama bvunzo.
GB/T8163 yakajairika simbi pombi, kuwedzera kune zvakajairika bvunzo zvinodiwa kuti fluid kutakura simbi pombi, maererano nezvinodiwa chibvumirano kuita flaring bvunzo uye kutonhora kukotama bvunzo.Zvinodiwa kugadzira kwemhando mbiri idzi pombi hazvina kuomarara. seaya emarudzi matatu okutanga.
Kugadzira: GB/T/8163 uye GB3087 yakajairika simbi pombi inotora choto chakavhurika kana kushandura kunyunguduka, kusvibiswa kwayo uye hurema hwemukati hwakanyanya.
GB9948kunyungudutswa kwechoto chemagetsi. Zvizhinji zvinowedzerwa kuhuni yekunatsa nzira ine zvishoma zvishongedzo uye hurema hwemukati.
GB6479uyeGB5310zviyero pachazvo zvinotsanangura zvinodiwa pakunatsa kunze kwechoto, nekusachena kudiki nekuremara kwemukati uye nemhando yepamusoro yezvinhu.
Iwo pamusoro akati wandei simbi pombi zviyero zvinogadzirwa muhurongwa hwemhando kubva pasi kusvika kumusoro:
GB/T8163＜GB3087＜GB9948＜GB5310＜GB6479
Sarudzo: pasi pemamiriro ezvinhu, GB/T8163 yakajairika simbi pombi inokodzera tembiricha yekugadzira isingasviki 350 ℃, kudzvanywa kuri pasi pe10.0mpa zvigadzirwa zvemafuta, mafuta uye gasi uye neruzhinji svikiro mamiriro;
Kune zvigadzirwa zveoiri, mafuta uye gasi svikiro, kana tembiricha yekugadzira yadarika 350 ℃ kana kudzvanywa kwakakura kupfuura 10.0mpa, zvakakodzera kusarudza.GB9948 or GB6479pombi yesimbi yakajairika;
GB9948 or GB6479chiyero chinofanirwawo kushandiswa kune mapaipi anoshandiswa padhuze nehydrogen kana mukushushikana ngura nharaunda.
General yakadzika tembiricha (isingasviki -20 ℃) uchishandisa kabhoni simbi pombi inofanira kushandiswaGB6479standard, iyo chete inotsanangura zvinodikanwa zveyakadzika tembiricha kukanganisa kuoma kwezvinhu.
GB3087 uyeGB5310zviyero zvakagadzirirwa zvakagadzirirwa boiler simbi pombi zviyero. "Boiler kuchengetedza mitemo yekutarisa" yakasimbisa kuti zvese zvakabatana nemachubhu ebhailer ndezvechikamu chekutarisisa, kushandiswa kwezvinhu uye chiyero kunofanirwa kuenderana nemirairo yekuchengetedzwa kwebhailer, saka, boiler, chiteshi chemagetsi, kupisa uye petrochemical kugadzirwa. mudziyo unoshandiswa mupombi pombi yeruzhinji unofanirwa kushandiswa (neiyo system supply) GB3087 kana yakajairwaGB5310.
Zvinokosha kucherechedza kuti mhando yakanaka simbi pombi mitemo, simbi pombi mitengo yakawandisa, akadaiGB9948kupfuura GB8163 mutengo wezvinhu ungangoita 1/5, saka, pakusarudzwa kwesimbi pombi zvinhu zviyero, zvinofanirwa kutariswa zvinoenderana nemamiriro ekushandiswa, zvese zvakavimbika uye zvehupfumi. Izvo zvinofanirwa kucherechedzwa kuti machubhu esimbi zvinoenderana neGB/T20801 uye TSGD0001, GB3087 uye GB8163 haizoshandiswe muGC1 pombi (kunze kwekunge ega ultrasonic, mhando isiri pasi peL2.5, inogona kushandiswa muGC1 (1) pombi dhizaini. kudzvinyirira kusingapfuuri 4.0Mpa).
