  风压计算用的风道标签是什么?,长距离掘进巷道通风时,风道进、出口风量差和风压差较大。为了选择合理的风机通风方式,有必要研究风道风量和风压的变化规律。传统的方法是通过经验或实验得到管道接头的平均泄漏风量,从而计算进气道的风量和压力。但是,对于长距离通风和各风道体积小,该方法计算的参数相对较小,会造成风机选型误差。

When ventilating long-distance tunnels, the air volume difference between the inlet and outlet of the air duct and the air pressure difference are large. In order to choose a reasonable ventilation mode of fan, it is necessary to study the variation law of air volume and pressure in the duct. The traditional method is to get the average leakage air volume of the pipe joint through experience or experiment, so as to calculate the air volume and pressure of the intake port. However, for the long-distance ventilation and the small volume of each duct, the parameters calculated by this method are relatively small, which will cause the error of fan selection.

  根据风量和空气压力平衡定律,风量的关系,空气压力和进气口的空气出口推导出根据不连续通风网络模型,并给出简化的近似关系作为一种新的方法来计算通风参数的风道。结合具体算例,发现参数的近似值与精确值高度相似,说明可以用近似关系进行计算,简单方便。结果表明,采用该方法计算长距离隧道的风量和风压更加科学。

  According to the law of air volume and air pressure balance, the relationship between air volume, air pressure and air outlet of air inlet, the model of discontinuous ventilation network is deduced, and the simplified approximate relationship is given as a new method to calculate the ventilation parameters of air duct。 Combining with a specific example, it is found that the approximate values of the parameters are highly similar to the exact values, which indicates that the approximate relationship can be used to calculate the parameters, which is simple and convenient。 The results show that the method is more scientific in calculating wind volume and pressure of long-distance tunnels。

  通风机是一种耗能大、体积大、占地面积广的设备。为节约风机能耗,降低运行成本,当前应重视通风空调系统的优化技术,以降低系统风道压降和消耗,合理匹配和优化运行调节。作者发现,从风机现场售后服务质量问题之前,业主决定,风扇,风扇使用现场调查,结果相当部分是不合理的通风系统设计、制造、安装和导致风机运行异常,出现通风机性能不能满足设计要求,过量的噪音、振动叶片断裂问题的通风系统改革后,风机正常运行。

  Fan is a kind of equipment with large energy consumption, large volume and wide area。 In order to save energy consumption of fans and reduce operating costs, attention should be paid to the optimization technology of ventilation and air conditioning system, in order to reduce the pressure drop and consumption of air ducts, rationally match and optimize operation regulation。 The author found that before the quality of after-sales service of fans, the owners decided to investigate the use of fans and fans。 The results showed that quite a part of unreasonable ventilation system design, manufacture, installation and abnormal operation of fans resulted in the failure of fan performance to meet the design requirements, excessive noise and ventilation with vibration blade breakage。 After the system reform, the fan operates normally。
