Dab tsi yog Qhov Txheej Txheem Txheej Txheem Rau Roj Hmab O-rings?

Roj hmab O-ring xam cov mis:

d (zes puab txoj kab uas hla)=a (O-ring tensile tus nqi: zoo li qub foob 1.035) [d (O-ntiv nplhaib puab hauv lub xeev pub dawb) + dw (O-ring cross-sectional diameter hauv lub xeev pub dawb)] -dw (hauv lub xeev pub dawb) O-nplhaib ntu taub)

D (txheej sab nraud ntawm qhov zawj)=2dw (hla-ntu txoj kab uas hla ntawm O-ntiv nplhaib hauv lub xeev pub dawb) [1-β (O-ntiv nplhaib compression 20%)] + d (puab txoj kab uas hla sab)

Qhov muab xam tshwj xeeb yog raws li nram no: Roj inlet lub rooj 0-ntiv nplhaib

Kauj Ruam 1: Hloov cov ntaub ntawv mus rau hauv lub mis kom tsim kom muaj ob qhov sib luag

Kev Sib Luag 1 32.2 = 1.035 (d {{4}} dw) -dw Kev Sib Luag 2 35 = 2dw (1-0.2) +32.2

Qhov thib ob kauj ruam yog los daws kom tau rau kab zauv 2:

Daws rau dw=1.75 (O-ntiv nplhaib ntu taub)

Qhov thib peb kauj ruam yog los hloov chaw dw=1.75 rau hauv Kev Sib Dauv 1: Daws rau d=31.05 (sab hauv taub ntawm O-ring)

Roj qhov hluav taws xob nkhaus 0-ntiv nplhaib

Thawj kauj ruam: Hloov cov ntaub ntawv rau hauv cov qauv coj los ua ob qho sib luag. Kev Sib Luag 1 31.4 = 1.035 (d {{4}} dw) -dw Sib Luag 2 35 = 2dw (1-0.2) +31.4

Qhov thib ob kauj ruam yog los daws kom tau rau kab zauv 2:

Daws rau dw=2.25 (O-ntiv nplhaib ntu taub)

Qhov thib peb kauj ruam yog los hloov chaw dw=2.25 mus rau hauv kab zauv 1: Daws rau d=30.26 (sab hauv taub ntawm O-ring)

Xam mis ntawm cov roj twj efficiency:

Flow × siab ÷ tam sim no ÷ voltage ÷ 3.6 Piv txwv: 54 × 200 ÷ 2.82 ÷ 7 ÷ 3.6=15.4%

1. Ntug dej nyuaj 60 %% P5 %% D;

2. Rhuav lub zog> 10MPa;

3. Elongation thaum tawg> 150%;

4. Kev nplua tsis tu ncua (70 ℃ × 72 teev)<>

5. Cov roj tsis kam thiab qhov hnyav nce (thaum nqus hauv 93 # roj av nrog 20% ​​methanol rau 72 teev)<>

6. Cov tsos ntawm cov khoom yog du thiab huv si, tsis muaj burrs thiab nti.
