Shenhai Kuphulika-Umboni
Chizindikiro chotsimikizira kuphulika muzowunikira zomwe sizingaphulike ndi chizindikiro chomwe chimafotokoza zamtundu wosaphulika., gulu kutentha, mtundu, ndi madera oyenerera a magetsi owunikira.
Kufotokozera Zolemba Zosaphulika:
Malinga ndi GB 3836 miyezo, chizindikiro choteteza kuphulika kwa zowunikira zimaphatikizansopo:
Mtundu wosaphulika + Zida Gulu + (Gulu la Gasi) + Kutentha Gulu.
1. Mtundu wosaphulika:
Table 1 Mitundu Yoyambira ya Kuphulika-Umboni
| Fomu yotsimikizira kuphulika | Chizindikiro chotsimikizira kuphulika | Fomu yotsimikizira kuphulika | Chizindikiro chotsimikizira kuphulika |
|---|---|---|---|
| Flameproof mtundu | EX d | Mchenga wodzazidwa mtundu | EX |
| Kuwonjezeka kwamtundu wa chitetezo | EX ndi | Encapsulation | EX m |
| Mtundu wa Barotropic | KUCHOKERA p | N-mtundu | EX n |
| Mtundu wotetezeka wamkati | EX EX ndi | Mtundu wapadera | EX ndi |
| Mtundu wowukira mafuta | EX kapena | Mtundu wosaphulika fumbi | EX A EX B |
2. Zida Gulu:
Zida zamagetsi za zophulika mpweya wa gasi umagawidwa kukhala:
Kalasi I: Zogwiritsidwa ntchito m'migodi ya malasha;
Kalasi II: Zogwiritsidwa ntchito mumlengalenga wophulika wa gasi kupatulapo migodi ya malasha.
Gulu lachiwiri losaphulika “d” ndi chitetezo chamkati “ndi” zida zamagetsi zimagawidwanso kukhala IIA, IIB, ndi makalasi a IIC.
Zida zamagetsi za fumbi loyaka chilengedwe chagawidwa:
Zida zamtundu wa A zoletsa fumbi; Zida zamtundu wa B zolimba fumbi;
Zida zamtundu wa A zoletsa fumbi; Zida zamtundu wa B zosagwira fumbi.
3. Kufotokozera Zolemba Zosaphulika:
Kutha kwa kusakaniza kwa gasi wophulika kufalitsa kuphulika kumawonetsa kuchuluka kwake kwa kuphulika kwake. Kukhoza kwakukulu kufalitsa kuphulika, kuopsa kwake kumakwera. Luso limeneli likhoza kuimiridwa ndi kusiyana kwakukulu koyesera kotetezeka. Kuphatikiza apo, kumasuka komwe mpweya wophulika, nthunzi, kapena akhoza kukhala anayaka zimasonyezanso mlingo wa ngozi kuphulika, kuyimiridwa ndi chiŵerengero chocheperako choyatsira panopa. Zida zamagetsi zamtundu wa Class II zosaphulika kapena chitetezo chamkati zimayikidwanso mu IIA, IIB, ndi IIC kutengera kusiyana kwawo koyenera koyeserera koyeserera kapena chiŵerengero chocheperako chapano.
Table 2 Ubale pakati pa Gulu la Zosakaniza za Gasi Wophulika ndi Kusiyana kwa Maximum Experimental Safe Gap kapena Minimum Igniting Current Ratio
| Gulu la gasi | Kupambana kwakukulu koyesa chitetezo MESG (m m) | Zocheperako poyatsira pano MICR |
|---|---|---|
| IIA | MESG≥0.9 | MICR - 0.8 |
| IIB | 0.9＞MESG≥0.5 | 0.8≥MICR≥0.45 |
| IIC | 0.5≥MESG | 0.45＞MICR |
4. Kutentha Gulu:
Kuyatsa kutentha wa kuphulika gasi osakaniza ndi malire kutentha kumene akhoza kuyatsa.
Zida zamagetsi zimagawidwa m'magulu a T1 mpaka T6 kutengera kutentha kwawo kwapamwamba kwambiri, kuonetsetsa kuti kutentha kwapamwamba kwa zipangizo sikudutsa mtengo wovomerezeka wa gulu la kutentha lofanana. Ubale pakati pa magulu a kutentha, zipangizo pamwamba kutentha, ndi kutentha kutentha kwa kuyaka mpweya kapena nthunzi zikuwonetsedwa mu Table 3.
Table 3 Ubale Pakati pa Kutentha Magulu, Zida Pamwamba Kutentha, ndi Kutentha kwa Mipweya Yoyaka kapena Nthunzi
| Kutentha kwa mlingo IEC/EN/GB 3836 | Kutentha kwapamwamba kwambiri kwa zida za T [℃] | Kutentha kwa Lgnition kwa zinthu zoyaka [℃] |
|---|---|---|
| T1 | 450 | T＞450 |
| T2 | 300 | 450≥T＞300 |
| T3 | 200 | 300≥T＞200 |
| T4 | 135 | 200≥T＞135 |
| T5 | 100 | 135≥T＞100 |
| T6 | 85 | 100≥T＞8 |
5. Zofunikira pakukhazikitsa Zizindikiro:
(1) Zolemba ziyenera kuyikidwa mowonekera pagulu lalikulu la zida zamagetsi;
(2) Zolembazo ziyenera kukhala zomveka bwino komanso zolimba pansi pa dzimbiri la mankhwala. Zizindikiro monga Eks, mtundu wosaphulika, gulu, ndi kutentha gulu akhoza embossed kapena debossed pa mbali zooneka casing. Zinthu zopangira cholembera ziyenera kukhala zosagwirizana ndi mankhwala, monga bronze, mkuwa, kapena chitsulo chosapanga dzimbiri.
