Amaliyot ishi 5 Ichki bosim ostidagi payvandlangan apparat elementlarini mustahkamlikka hisoblash; Sferik apparatlarni xisoblash

2.3. Listli filtr konussimon dnishesi devorining qalinligini aniqlash (2.3a-rasm).

B e r i l g a n: : ichki bosim P=0,4MPa; filtr balandligi H_s=3500 mm; ichki diametr D=1600 mm; konus cho’qqisining burchagi 2=90⁰; xisoblangan temperatura t=60^oC; dnishening materiali po’lat 10; ishchi holat ruxsat etilgan kuchlanish []=127 MPa, gidravlik sinovlar uchun []_i=147 MPa; muhit zichligi _s=1300 kg/m³; Devorning hisoblangan qalinligiga qo’shimcha c=2,54 mm. Payvand choki mustahkamlik koeffitsiyenti =0,9.

Dnishening hisoblangan va bajaruvchi qalinligi tegishli ravishda quyidagiga tengdir.

2.3 – rasm. Listli vertikal filtr (a) va uning konussimon dnishnning hisoblash sxemasi (b).

1 – qobiq; 2 – qopqoq; 3 – kollektor;

4 – tayanch; 5 – filttrlovchi element.

S_k=s_k.p+c+c₀=4,84+2,54+0,62 = 8 mm.

(s_k-c)/D=(8-2,54)10^-3/1,6=3,4410^-3; 0,1/cosα=0,1/cos45⁰=0,14 va 3,4410^-3<0,14

bo’lganligi uchun, formulani ishlatilish shartlari bajarilyapti.
