3mm jawaab celin degdeg ah nalalka rusheeyaha

Qoraalka daabacan ee nalka rusheeyaha ee 3mm waa "ZJCY". Marka la barbar dhigo 5mm nalka rusheeyaha, jawaabteedu waxay noqon doontaa mid dhakhso badan, RTI ≤ 50, halkaas oo RTI ay tahay iskudar lagu cabbiro xaaladaha caadiga ah si loo cabbiro dareenka guluubka rusheeyaha. Odhaah:RTI= τ u ^½

Halkee: RTI - isku-xirnaanta waqtiga jawaabta, cutub (m * s)^½;
τ－ Wakhtiga jawaabta joogtada ah, ee s;
u - heerka socodka gaaska, halbeegga: m/s
Tayada nalka rusheeyaha waxay si buuxda u waafaqsan tahay heerka qaranka Shiinaha GB18428-2010. Dhexroorka nalka rusheeyuhu waa 3mm, ka leexashada dhexroorka magacu ma dhaafi doono ± 0.1mm; Dhererkiisu waa 23mm ka leexashada dhererka magaca ah kama badnaan doono 0.5mm.
Celceliska culeyska burburinta guluubka rusheeyuhu waa 3600n. Inta lagu jiro tijaabada, nalka rusheeyaha ayaa lagu hagaajin doonaa inta u dhaxaysa walxaha taageeraya si habboon, iyo walxaha taageeraya waxay ka samaysan yihiin bir. Adkeydka Rockwell waa (44 ± 6) HRC, kaas oo buuxiya shuruudaha adeegga u dhigma. Kadibna, mari culays labis ah oo ay la socdaan dhidibka guluubka rusheeyaha ilaa guluubka rusheeyaha uu dillaaco, iyo heerka korodhka culeysku waa (250 ± 25) N / s. Weecaadda ugu badan ee qalabka loo isticmaalo in lagu cabbiro culayska burburinta waa in aanu dhaafin ± 1% qiimaha la cabbiray. Isticmaal kooxo badan oo xogta la cabiray si aad u xisaabiso celceliska qiimaha iyo weecanka caadiga ah ee culayska burburinta oo aad xukunto in natiijadu ay buuxinayso heerarka la cayimay.
