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

3)室內外溫差較大時,應采用室外空氣來降低發(fā)電機房溫度;

移動電站控制室如需通風,應按如下方式處理:
Ifthecontrolroomofmobilepowerstationneedsventilation,itshallbetreatedasfollows:
1)移動電站與防空庫連接時,從防空庫向電站控制室提供新鮮空氣;
1)Whenthemobilepowerstationisconnectedwiththeairdefensedepot,freshairisprovidedfromtheairdefensedepottothecontrolroomofthepowerstation;
2)移動電站獨立設置時,柴油電站應在控制室設置獨立的通風系統(tǒng),提供新風,并設置過濾通風裝置。
2)Whenthemobilepowerstationissetindependently,thedieselpowerstationshallbeequippedwithanindependentventilationsysteminthecontrolroomtoprovidefreshairandfilterventilationdevice.
移動電站儲油間應設排風裝置,排風通風次數每小時不得少于5次,連接儲油間的排氣管應設防火閥,防火閥在70℃時關閉。
Theoilstorageroomofthemobilepowerstationshallbeequippedwithexhaustdevice,andthenumberofexhaustventilationshallnotbelessthan5timesperhour.Theexhaustpipeconnectingtheoilstorageroomshallbeequippedwithfiredamper,whichshallbeclosedat70℃.
