發(fā)電機(jī)組機(jī)房高溫如何處理?
Theventilationandcoolingintheengineroomofgasgeneratorisveryimportant,especiallyinthecaseofcontinuousoperationofdieselgenerator.Althoughthegeneratorsethasgreatadvantagesincooling,weshouldalsopayattentiontothedesignofthemachineroom.
1)當(dāng)室內(nèi)外空氣溫差小、水量不足時(shí),建議采用直接蒸發(fā)式冷風(fēng)機(jī)組來降低發(fā)電機(jī)房溫度。
2)當(dāng)水量充足,水溫達(dá)到要求時(shí),建議采用水冷法降低發(fā)電機(jī)房溫度;

3)室內(nèi)外溫差較大時(shí),應(yīng)采用室外空氣來降低發(fā)電機(jī)房溫度;

移動(dòng)電站控制室如需通風(fēng),應(yīng)按如下方式處理:
Ifthecontrolroomofmobilepowerstationneedsventilation,itshallbetreatedasfollows:
1)移動(dòng)電站與防空庫連接時(shí),從防空庫向電站控制室提供新鮮空氣;
1)Whenthemobilepowerstationisconnectedwiththeairdefensedepot,freshairisprovidedfromtheairdefensedepottothecontrolroomofthepowerstation;
2)移動(dòng)電站獨(dú)立設(shè)置時(shí),柴油電站應(yīng)在控制室設(shè)置獨(dú)立的通風(fēng)系統(tǒng),提供新風(fēng),并設(shè)置過濾通風(fēng)裝置。
2)Whenthemobilepowerstationissetindependently,thedieselpowerstationshallbeequippedwithanindependentventilationsysteminthecontrolroomtoprovidefreshairandfilterventilationdevice.
移動(dòng)電站儲(chǔ)油間應(yīng)設(shè)排風(fēng)裝置,排風(fēng)通風(fēng)次數(shù)每小時(shí)不得少于5次,連接儲(chǔ)油間的排氣管應(yīng)設(shè)防火閥,防火閥在70℃時(shí)關(guān)閉。
