发电机组机房高温如何处理?
Theventilationandcoolingintheengineroomofgasgeneratorisveryimportant,especiallyinthecaseofcontinuousoperationofdieselgenerator.Althoughthegeneratorsethasgreatadvantagesincooling,weshouldalsopayattentiontothedesignofthemachineroom.
1)当室内外空气温差小、水量不足时,建议采用直接蒸发式冷风机组来降低发电机房温度。
2)当水量充足,水温达到要求时,建议采用水冷法降低发电机房温度;

3)室内外温差较大时,应采用室外空气来降低发电机房温度;

移动电站控制室如需通风,应按如下方式处理:
Ifthecontrolroomofmobilepowerstationneedsventilation,itshallbetreatedasfollows:
1)移动电站与防空库连接时,从防空库向电站控制室提供新鲜空气;
1)Whenthemobilepowerstationisconnectedwiththeairdefensedepot,freshairisprovidedfromtheairdefensedepottothecontrolroomofthepowerstation;
2)移动电站独立设置时,柴油电站应在控制室设置独立的通风系统,提供新风,并设置过滤通风装置。
2)Whenthemobilepowerstationissetindependently,thedieselpowerstationshallbeequippedwithanindependentventilationsysteminthecontrolroomtoprovidefreshairandfilterventilationdevice.
移动电站储油间应设排风装置,排风通风次数每小时不得少于5次,连接储油间的排气管应设防火阀,防火阀在70℃时关闭。
Theoilstorageroomofthemobilepowerstationshallbeequippedwithexhaustdevice,andthenumberofexhaustventilationshallnotbelessthan5timesperhour.Theexhaustpipeconnectingtheoilstorageroomshallbeequippedwithfiredamper,whichshallbeclosedat70℃.
