Kureba:
Iyo yakajairwa kureba kweiyo simbi mapaipi ndeye 4 000 mm ~ 12 000 mm. Mushure mekutaurirana pakati pemutengesi uye mutengi, uye zadza chibvumirano chesimbi nehurefu hwakakura kupfuura gumi nembiri mm kana mupfupi kupfuura i 000 mm asi kwete mupfupi kupfuura 3 000 mm; Pfupi kureba huwandu hwembambo simbi zvisingasviki 4,000 mm asi isingasviki zviuru zvitatu mm haingapfuure 5% yehuwandu hwehuwandu hwesimbi.
Kuendesa uremu:
Kana pombi yesimbi yasvitswa maererano neyekutsvaira kunze kwechidimbu Inogona zvakare kuturikwa zvichienderana nehuremu hweruzivo.
Pipi pombi iri kuendeswa maererano neyekutsvaira kwekunze uye madziro emadziro, pombi yesimbi inotumirwa maererano nehuremu chaihwo; iyo yekugovera uye inoda mapato anotaurirana. Uye zvinoratidzwa muchibvumirano. Iyo pombi yesimbi inogona zvakare kuunzwa zvinoenderana nehuremu hwerementical.

a) simbi simbi pombi: ± 10%;
b) batch yega yega yechibage chesimbi ine shoma saizi yegumi t: ± 7.5%.
Hydraust Test:
Iyo pombi yesimbi inofanira kuedzwa hydraliucy imwe neimwe. Iyo yakanyanya kuongororwa kudzvanywa ndeye 20 MPA. Pasi pekudzvinyirirwa kwekuyedza, nguva yakasindimara haifanirwe kunge isiri pasi pegumi, uye pombi yesimbi haifanire kusvetuka.
Mushure mekunge mushandisi achibvumirana, iyo hydraulic bvunzo inogona kutsiviwa neEddy zvazvino kuongororwa kana magineti Flux leage kuongororwa.
