Urefu:
Iyo yakajairika urefu hwemapombi esimbi ndeye 4 000 mm ~ 12 000 mm. Mushure mekubvunzana pakati pemutengesi nemutengi, uye kuzadza chibvumirano, inogona kuendeswa simbi mapaipi nehurefu hunopfuura 12 000 mm kana kupfupika kupfuura I 000 mm asi kwete kupfupika kupfuura 3 000 mm; hurefu hupfupi Huwandu hwepombi dzesimbi dziri pasi pe 4,000 mm asi dzisingasviki 3,000 mm hadzifanire kudarika 5% yehuwandu hwemapombi esimbi akaunzwa.
Delivery uremu:
Kana pombi yesimbi ichiunzwa zvinoenderana nedhayamita rekunze rekunze uye ukobvu hwemadziro hwezita kana dhayamita yemukati yemukati uye dhayamita remadziro, pombi yesimbi inounzwa zvinoenderana nehuremu chaihwo. Inogonawo kuendeswa maererano nehuremu hwe theoretical.
Kana iyo pombi yesimbi inounzwa maererano nezita rekunze dhayamita uye hushoma rusvingo ukobvu, pombi yesimbi inounzwa maererano nehuremu chaihwo; mapato ekupa nekudiwa anotaurirana. Uye inoratidzwa muchibvumirano. Iyo pombi yesimbi inogonawo kuendeswa maererano nehuremu hwe theoretical.
Weight tolerance:
Zvinoenderana nezvinodiwa nemutengi, mushure mekubvunzana pakati pemutengesi nemutengi, uye muchibvumirano, kutsauka pakati pehuremu chaihwo uye huremu hwekufungidzira hwepombi yesimbi yekutakura huchasangana nezvinodiwa zvinotevera:
a) Single simbi pombi: ± 10%;
b) Batch rimwe nerimwe remapombi esimbi ane saizi shoma yegumi t: ± 7.5%.
Hydraustatic Test:
Iyo pombi yesimbi inofanirwa kuongororwa hydraulically imwe neimwe. Iyo yakanyanya test pressure ndeye 20 MPa. Pasi pekumanikidzwa kwekuedza, nguva yekudzikamisa inofanira kunge isiri pasi pe10 s, uye pombi yesimbi haifaniri kudonha.
Mushure mekunge mushandisi abvuma, iyo hydraulic bvunzo inogona kutsiviwa needdy yazvino kuyedza kana magineti flux kuvuza kuyedzwa.
Nondestructive Test:
Mapaipi anoda kuongororwa zvakanyanya anofanirwa kuongororwa ultrasonically imwe neimwe. Mushure mokunge nhaurirano inoda kubvumirwa kwebato uye inotsanangurwa muchibvumirano, kumwe kuedza kusina kuparadza kunogona kuwedzerwa.
Flattening Test:
Machubhu ane dhayamita rekunze rakakura kudarika 22 mm achaiswa muyedzo yekubata bata. Hapana delamination inooneka, mavara machena, kana tsvina inofanirwa kuitika panguva yese yekuyedza.
Flaring Test:
Zvinoenderana nezvinodiwa nemutengi uye zvakataurwa muchibvumirano, pombi yesimbi ine dhayamita yekunze ≤76mm uye ukobvu hwemadziro ≤8mm inogona kuitwa flaring test . Kuedza kwakaitwa pakamuri tembiricha ine taper ye60 °. Mushure mekupisa, mwero wekupisa wedhayamita yekunze unofanirwa kusangana nezvinodiwa zvetafura inotevera, uye zvinhu zvekuyedza hazvifanirwe kuratidza kutsemuka kana kubvaruka.
