American standard vharuvhu kumanikidza uye yenyika yakajairwa vharuvhu kumanikidza kutendeuka sumo

Isu tinowanzoshandisa Pn, Kirasi, inzira yekumanikidza, mutsauko ndewekuti vanomiririra kumanikidza kuri pasi peyakaenderana tembiricha tembiricha yakasiyana, Pn European system inoreva kumanikidza kunoenderana pa120 ℃, nepo American standard ichireva kumanikidza kunoenderana pa 425.5 ℃. Naizvozvo, mukuchinjana kweinjiniya hakugone kungoita shanduko yekumanikidza, senge CLass300 # kungoita nekumanikidza kushandurwa kunofanirwa kuve 2.1 Mpa, asi kana iwe ukafunga nezvekushandiswa kwetembiricha, kumanikidza kwayo kunoenderana kuchakwira, zvinoenderana nechero tembiricha yekumanikidza test yakaenzana ne5.0 Mpa.

Kune maviri marudzi evhavha system: imwe iGerman (kusanganisira China) semumiriri weyakajairika tembiricha (China i100 madigiri, Germany i120 madigiri) inobvumidzwa kushanda kumanikidza sechiyero cheiyo "zita rezita kumanikidza" system. Imwe ndiyo "tembiricha yekumanikidza" inomiririrwa neUnited States, iyo inoenderana neinobvumidzwa mashandiro ekumanikidza pane imwe tembiricha. Mune tembiricha yekumanikidza system yeUnited States, ese matanho anoenderana ne454 degrees kunze kwe150LB yakavakirwa pamadhigirii mazana maviri negumi. Iyo 150 lb (150psi = 1MPa) Kirasi 25 kabhoni simbi vharuvhu ine inotenderwa kushushikana kwe1MPa pamadhigirii mazana maviri negumi, asi kushushikana kunotenderwa patembiricha yemukati kwakakura kwazvo kupfuura izvozvo, ingangoita 2.0MPa.

Naizvozvo, zvinowanzo kutaurwa kuti iro rezita rekumanikidza rinoenderana neAmerican Standard 150LB iri 2.0MPa, iro rezita rekumanikidza rinoenderana ne300LB iri 5.0MPa, zvichingodaro. Naizvozvo, iyo yekumanikidza kumanikidza uye tembiricha yekumanikidza giredhi haigone kuchinjwa zvinoenderana neyakaomeswa shanduko fomula. Pn inomiririra manhamba ekodhi inoenderana nekumanikidza, ndeyekupa yakaringana denderedzwa nhamba kuti iratidzwe, Pn inenge yakaenzana neyakajairika tembiricha yekumanikidza Mpa nhamba, inowanzo shandiswa mukumanikidza kwemazita emagetsi.

Kune iyo vharuvhu yekudzora yekabhoni simbi vharuvhu muviri, inoreva iyo yepamusoro inobvumidzwa kushanda kumanikidza kana yaiswa pazasi pe200 ℃; Kune yakakanda simbi muviri, iyo yakawanda inobvumidzwa yekumanikidza yekumanikidza sevhisi pazasi pe120 ° C; Kune mavhavha ekudzora ane isina simbi miviri, yakanyanya kubvumidzwa yekumanikidza yekumanikidza sevhisi pazasi pe250 ° C. Kana iyo tembiricha yekushanda ichiwedzera, kumanikidza kwekumanikidza kwemuviri wevharuvhu kunoderedzwa. MaAmerican standard mavhavha anoratidza zita rezita kumanikidza muundi kirasi, inova kuverenga kweye inosunga tembiricha uye kumanikidza kwesimbi zvinoenderana ANSIB16.34. Chikonzero chikuru nei paundi giredhi nemazita ekumanikidza asiri e - ku - imwe tsamba ndeyekuti pondo giredhi uye zita rekumanikidza rine akasiyana tembiricha datum.

Isu tinowanzo shandisa software kuverenga, asi zvakare zvakakosha kuti uzive mashandisiro matafura kutarisa kumusoro uremu mamaki. MuJapan, kukosha kukuru kweK kunoshandiswa kuratidza padanho rekumanikidza. Zvekumanikidza gasi, kuChina, isu tinowanzoshandisa hombe unit "kg" (pane kuti "jin"), iyo unit ye ​​kg. Chidimbu chekumanikidza makirogiramu pasentimendi 2, uye kilogiramu imwe yekumanikidza ikirogiramu imwe chete yesimba iri kuita pasikweya mita imwe. Saizvozvowo, inoenderana neyekunze, yekumanikidza kwegesi, inowanzo shandiswa yekumanikidza yuniti "psi", iyo unit iri "1pound / inch2 ″, iri" Pounds pa square square ", iro zita reChirungu izere maPondo pa square square.

Asi zvinowanzozivikanwa seyuniti yemasa, kana kuti LB., iri chaizvo LB. Ndiro simba remapaundi. Ese mayuniti mumetric units anogona kugadziriswa: 1psi = 1 pondo / Inch2 -0.068bar, 1bar≈14.5psi≈0.1MPa, Europe neUnited States nedzimwe nyika dzaishandiswa kushandisa psi sechikamu. MuClass600 neClass1500 inoenderana neiyo yeEuropean standard uye United States standard ine mbiri mbiri dzakasiyana, 11MPa (inoenderana nekirasi yemazana matanhatu emapaunzi) ndiyo yeEuropean system zvigadzirwa, izvi zviri mu "ISO7005-1-1992 Steel Flanges" mukati izvo zvinopihwa; 10MPa (inoenderana nekirasi mazana matanhatu emapaunzi) ndiyo American system mutemo, iyo yakatarwa muASMEB16.5. Naizvozvo, hazvigone kunyatso taurwa kuti inoenderana kirasi yemapaundi mazana matanhatu ndeye 11MPa kana 10MPa, uye zvinopihwa zvehurongwa hwakasiyana zvakasiyana.

Valve system inowanzo ine marudzi maviri: imwe iGerman (kusanganisira China) semumiriri kune tembiricha yakajairwa (China i100 madhigirii, Germany madigiri zana nemakumi maviri) inobvumidzwa kushanda kumanikidza sechiyero che "zita rekumanikidza" system. Imwe ndiyo "tembiricha yekumanikidza" system inomiririrwa neUnited States, iyo inoenderana neinobvumidzwa kushanda kumanikidza pane imwe tembiricha. MuUnited States, iyo tembiricha yekumanikidza sisitimu yakavakirwa pamadhigiri makumi mana nemakumi mana nematanhatu kunze kwe150LB zvichibva nemadhigirii mazana maviri negumi.

Semuenzaniso, iyo 150LB. # 25 kabhoni simbi vharuvhu ine inotenderwa kushushikana kwe1MPa pamadhigirii mazana maviri negumi, nepo kushushikana kunotenderwa patembiricha yemukati kuri kukuru kwazvo kupfuura iko, inenge 2.0MPa. Naizvozvo, zvinowanzo kutaurwa kuti iro rezita rekumanikidza rinoenderana neAmerican Standard 150LB iri 2.0MPa, iro rezita rekumanikidza rinoenderana ne300LB iri 5.0MPa, zvichingodaro. Naizvozvo, iyo yekumanikidza kumanikidza uye tembiricha yekumanikidza giredhi haigone kuchinjwa zvinoenderana neyakamanikidza shanduko fomula.
