      如何保证管道风机选型的合理性?以下是通风管道专业人员介绍:

    柬埔寨一分PK拾  How to ensure the rationality of the selection of duct fan? The following is the introduction of ventilation pipe professionals:

      1. 首先,确定所输送气体的性质(气体是否清洁、是否高温、是否易燃易爆等)和所需风压、风量范围,确定风机类型;

      1. Firstly, determine the nature of the conveyed gas (whether the gas is clean, high temperature, inflammable and explosive, etc.) and the required air pressure, air volume range, determine the type of fan;

    柬埔寨一分PK拾  2. 计算选型后,可根据需要添加一定量的余量,确定最大风量和风压,参考选型表。

      2。 After calculating the selection, a certain amount of allowance can be added according to the need to determine the maximum air volume and pressure, referring to the selection table。

      3.确定实际风压,根据管道条件和伯努利方程将其转换为实验条件下的风压;

      3. Determine the actual wind pressure and convert it into the wind pressure under the experimental conditions according to the pipeline conditions and Bernoulli equation.

      4. 根据实际风量和实验风压,确定相应类型管道风机的模型,并通过性能曲线选择高效区域风机。

      4. According to the actual air volume and the experimental air pressure, the model of the corresponding type of duct fan is determined, and the high-efficiency regional fan is selected through the performance curve.

      对于通风管道冲程机在设计管道时首先必须从产品数据中了解三个参数:风量、风压、噪声,下面由通风管道专业人员来介绍:

      For the design of ventilation duct stroke machine, three parameters must be known from the product data: air volume, air pressure and noise. The following is introduced by the ventilation duct professionals:

      1。 风量:以确定供气管道的大小。

      1. Air volume: to determine the size of the supply gas pipeline.

      2. 风压:又称外静压。为了计算出供气过程中克服阻力所需的参数。简而言之,它就是能把风送多远的力量。

      2. Wind pressure: also known as external static pressure. In order to calculate the parameters needed to overcome the resistance in the process of gas supply. In short, it is the power that can carry the wind far.

      3。噪声:产品技术参数的噪声只是相对的,因为噪声随条件的不同而变化。

    柬埔寨一分PK拾  3。 Noise: The noise of technical parameters of products is only relative, because the noise varies with different conditions。
