The transportation volume of pneumatic conveying equipment is related to the diameter of transportation pipeline. Different industries and transportation requirements have different pipe sizes. The larger the volume of conveying powder, the larger the diameter of powder pipeline, but the connection of pipeline is also very important. Incorrect connections are more likely to cause faults such as steam leakage, damage or blockage. When conveying powder, the pneumatic conveying pipeline is installed in this way.

输送粉料时气力输送的管道这样安装才对。

When conveying powder, the pneumatic conveying pipeline is installed in this way.

在安装输送粉料气力输送管道时，注意管道与粉料气力输送设备的紧密连接。活接头和垫圈不移位。在粉料气力输送的管道系统中,水平管道运输道路的平面度误差值不得超过三分之一,总长度不得超过30毫米,垂直管道运输道路的平面度误差值不得超过一次一千,和总长度不得超过20毫米。如果你想使用无缝管或焊接管作为进料管，你可以使用法兰和夹紧连接的方法。这种类型的连接称为活连接方法。供水管的连接处应尽可能保持同轴，以使其位置不发生偏移。反之，电阻下降幅度大，如果情况很糟，原材料就会沉积在界面处，堵塞。

When installing the pneumatic conveying pipeline for conveying powder, pay attention to the close connection between the pipeline and the pneumatic conveying equipment for powder. The Union and washer are not displaced. In the pipeline system of powder pneumatic conveying, the flatness error value of horizontal pipeline transportation road shall not exceed one third, the total length shall not exceed 30mm, the flatness error value of vertical pipeline transportation road shall not exceed 1000 at a time, and the total length shall not exceed 20mm. If you want to use seamless pipe or welded pipe as feed pipe, you can use flange and clamping connection. This type of connection is called a live connection method. The connection of the water supply pipe shall be kept coaxial as far as possible so that its position does not deviate. On the contrary, the resistance decreases greatly. If the situation is very bad, the raw materials will be deposited at the interface and blocked.

为了改善粉料气力输送系统中的管道连接，在管道和弯头中添加螺旋桨是有意义的，因为它们容易堵塞，从而提高动力。改变后，粉体气力输送设备的可能性超过了原设计指标。而管道加固仅仅是指合理地提高管道和管件的使用寿命，从而减少维护和保护的力度。

In order to improve the pipeline connection in the powder pneumatic conveying system, it is meaningful to add propellers in the pipeline and elbow, because they are easy to be blocked, so as to improve the power. After the change, the possibility of powder pneumatic conveying equipment exceeds the original design index. Pipeline reinforcement only refers to reasonably improving the service life of pipelines and fittings, so as to reduce the strength of maintenance and protection.
