Yuav ua li cas thiaj li hlawv tawg ntawm Hmoov Txheej
Cov nram qab no yog cov yam ntxwv uas ua rau kom tawg tawg ntawm hmoov txheej
(A) Cov plua plav concentration tshaj qhov qis dua
Vim yog cov laj thawj no, cov plua plav concentration hauv chav hmoov lossis rhiav tshaj qhov kev txwv qis qis, yog li tsim cov xwm txheej tseem ceeb rau cov hmoov hlawv tawg. Yog hais tias qhov ignition qhov nruab nrab, qhov hluav taws kub yuav tshwm sim
(B) hmoov thiab xim khw sib tov
Hauv qee qhov chaw ua haujlwm, vim yog thaj chaw me me ntawm lub rhiav, txhawm rau txuag lub rhiav, cov hmoov txheej thiab xim pleev xim rau hauv ib lub rhiav. Ob txheej ntawm cov cuab yeej tau muab tso rau ntawm ib sab los yog hauv ib kab, qee zaum siv cov xim hnyav hnyav, qee zaum siv cov hmoov txau, uas ua rau cov xim pleev xim rau tag nrho cov rhiav nrog cov pa taws tsis zoo, thiab cov plua plav tawm los ntawm cov khoom siv. hmoov txau cov txheej txheem ntab hauv qhov kev cob qhia, tsim cov hmoov-pas sib xyaw ib puag ncig, uas muaj kev ua haujlwm siab. Muaj kev pheej hmoo ntawm hluav taws thiab tawg
(C) Ignition qhov chaw
Lub ignition qhov tshwm sim los ntawm hmoov combustion mas muaj xws li cov nram qab no cov xwm txheej:
- Hluav taws kub, Ib qho hluav taws xob hluav taws xob uas ua rau cov hmoov hluav taws kub hnyiab thiab yog ib qho ntawm cov hluav taws kub txaus ntshai tshaj plaws. Yog tias qhov chaw hmoov av nyob rau hauv qhov chaw muaj kev phom sij, muaj kev sib txuas, kev txiav cov pa oxygen, lub teeb hluav taws xob sib tw, sib tw luam yeeb teeb, tswm ciab, thiab lwm yam, uas yuav ua rau hluav taws kub thiab tawg.
- Thaum tshav kub kub qhov chaw, nyob rau hauv cov phom phom phom phom, ib daim ntawm liab-hluav taws kub hlau, lub teeb uas tsis yog-explosion-proof dheev tawg, lub resistive hlau yog dheev txiav tawm, lub infrared board yog energized thiab lwm yam combustion qhov chaw yuav ua rau cov phom kub. .
- Cov hluav taws xob electrostatic tawm hauv chav hmoov yog txwv. Thaum cov plua plav concentration ntawm cov xuab zeb blasting thiab hmoov txau phom tuaj rau hauv kev sib cuag nrog lub workpiece los yog cov hmoov chav tsev dheev nrog electrostatic sparks, los yog thaum lub motors thiab cov khoom siv hluav taws xob ignited, cov hmoov yuav hlawv.
