  根据被输送气体的性质,选用不同用途的风机。例如,空调净化工程中输送清洁空气,或含尘气体流经风机时已经过净化,含尘浓度不超过150mg/m3时,可选择一般通风换气工程用的风机;输送腐蚀性的气体,要选用防腐风机。
  According to the nature of the transported gas, the fans of different uses are selected. For example, when air cleaning works are carried out in clean air or when dusty gas passes through the fan, it has been cleaned. When the dust concentration is no more than 150mg/m3, a fan can be selected for general ventilation and ventilation engineering.
  输送易燃易爆气体火含尘气体时,要选用防爆风机或排尘风机。但在选择具体的风机型号和规格时还要根据某种类型风机产品样本上的性能表或特性曲线图才能确定。
  When transporting flammable and explosive gas, it is necessary to choose explosion-proof fan or exhaust fan. But when selecting the specific type and specifications of the fan, the performance table or characteristic curve on the sample of a type of fan product should also be determined.
  集中式除尘系统阻力不平衡的情况在运行中是难免的,因此,在与吸尘罩连接的垂直管段上设调节阀门。常见的调节阀门有蝶阀斜插板阀等,在吸入段管道上,一般不容许采用直插板阀,因为它容易引起管道堵塞。作为调节风量用。

  The imbalance of the centralized dust removal system is unavoidable in operation. Therefore, the valve is set on the vertical pipe section connected to the hood. Common regulating valves are butterfly valve slanting plate valves, etc., in the suction section pipe, generally do not allow the use of straight plug valve, because it is easy to cause pipe plugging. It is used as a regulating air volume.
  无论是斜插板或蝶阀,都必须装设在垂直管段上。因为阀板前后产生强烈的涡旋,粉尘很容易沉积,如果这类阀板装在斜管或水平管段上,沉积粉尘还会妨碍阀板的开关或堵塞管道。
  Both slanting and butterfly valves must be installed on the vertical tube section. Because the strong vortex is generated before and after the valve plate, dust is easy to deposit. If these valve plates are mounted on inclined tubes or horizontal pipes, the deposition of dust will also impede the switch or blockage of valves.
  正确选择风机室保证通风系统正常运行的一个重要条件。所谓正确选择风机,主要是指根据被输送气体的性质和用途选择不同用途的风机;选择的风机要满足系统所需要的风量,同时风机的风压要能克服系统的阻力。
  It is an important condition for the correct selection of the fan room to ensure the normal operation of the ventilation system. The so-called correct selection of fans is mainly based on the nature and purpose of the transported gas to choose different uses of fans. The selected fans need to meet the air volume required by the system, while the wind pressure of the wind turbine can overcome the resistance of the system.
