Kuyika kwa ulusi wa waya ndi kuyika kwa ulusi

Kuyika kwa ulusi ndi mtundu watsopano wa zomangira za ulusi, zomwe zimatha kukumana ndi muyezo wapadziko lonse wa ulusi wolondola kwambiri wamkati pambuyo potsitsa, ndipo magwiridwe ake ndi abwino kuposa ulusi wopangidwa pogogoda mwachindunji. Zingwe za ulusi zimagawidwa m'magulu a ulusi wamba ndi zomangira za ulusi wokhoma malinga ndi ntchito yogwiritsira ntchito, ndipo zimatha kugawidwa muzitsulo zosapanga dzimbiri zachitsulo ndi zingwe zamkuwa zachitsulo.

(1) Zosankhidwa molingana ndi ntchito yoyika ulusi

A, zoyika za ulusi wamba (Zoyika Zopanda Ufulu) zolembedwa "FR"

B, Screw Lock Insert zolembedwa "SL"

(2) Zosankhidwa molingana ndi ulusi woyikapo

A, Cr-Ni chuma chosapanga dzimbiri: kudzera pakuphatikiza mphamvu ndi zinthu, nthawi zambiri amagwiritsidwa ntchito popanga mawonekedwe ang'onoang'ono, ma aluminiyamu aloyi, madzi am'nyanja, madzi okhala ndi chlorine, komanso kukana dzimbiri.

B, Copper alloy material: pakufunika mkuwa kapena nthawi zambiri kusintha kasinthasintha wa ulusi kugwirizana ntchito; Gwiritsani ntchito ngati kuli kofunikira ngati kuyendetsa magetsi kapena kudzipaka mafuta.

C, Superalloy zakuthupi: kutentha pa 500-750 ℃ ​​ntchito kutentha kugonjetsedwa; Imagwiritsidwa ntchito paukadaulo wophatikizira muzamlengalenga, injini za ndege ndi ma turbine compressor amkati omwe amagwira ntchito pa 750 ° C.

(3) Malingana ndi dongosolo la ulusi la ulusi woyika gulu

A, muyezo wapadziko lonse lapansi wa ISO "M, MJ" mndandanda wa ulusi woyika ulusi "M", "MJ"; Spark plug Thread (Spark plug Thread) lowetsani waya pamndandanda uno

B, UNIFIED Thread "UN" Series ulusi braces (UNIFIED Thread Series)

Ulusi wosalala wolembedwa "UNC", ulusi wabwino wolembedwa "UNF", ulusi wabwino kwambiri wolembedwa "UNEF"

C, ulusi wosasindikizidwa wa Pipe Thread (British Standard Pipe Thread) nambala ya ulusi ndi "G"

(4) Zosankhidwa molingana ndi kayendetsedwe ka kuzungulira kwa ulusi woyikapo

A, kulowetsa ulusi kumanja

B, ulusi wolowetsa kumanzere

(5) Malinga ndi gulu la ulusi woyikapo cholumikizira:

A, yokhala ndi chogwirira ntchito choyikapo B, popanda chogwirira ntchito choyikapo ulusi

(6) Malinga ndi pamwamba pa ulusi amaika ❖ kuyanika amagawidwa

A, palibe ulusi wokutira pamwamba (kuyika ulusi)

B, pamwamba pa ulusi wokutidwa ndi ulusi monga: siliva, cadmium plating, etc.
