Two blade Roots fan

二叶罗茨风机最早的型号是L系列，在我国建国之初二叶罗斯风机根据苏联的设计图纸设计发明出来，当时的二叶罗茨风机都是L系列的，主要用于一些大型的工况系统中。随着我国各行各业的发展，三叶罗茨风机根据二叶罗茨风机衍生出来。

The earliest model of the two leaf Roots fan was the L series. In the early days of China's founding, the two leaf Roots fan was designed and invented based on the design drawings of the Soviet Union. At that time, the two leaf Roots fans were all L series and were mainly used in some large-scale operating systems. With the development of various industries in China, the three leaf Roots blower has been derived from the two leaf Roots blower.

二叶罗茨风机的特点

Characteristics of Two Leaf Roots Fan

因为早期的二叶罗茨风机都是用的较大型的工况中，所以二叶罗茨风机的特点是型号大，体积大，风量大压力大，二叶罗茨风机的型号适用于需求风量较大的环境中。

Because early two leaf roots fans were used in larger operating conditions, the characteristics of two leaf roots fans were large models, large volumes, high air volume, and high pressure. The model of two leaf roots fans is suitable for environments with high air demand.

三叶罗茨风机的特点

Characteristics of Three Leaf Roots Fan

三叶罗茨风机是由二叶罗茨风机衍生出来的产品，所以三叶罗茨风机的特点是型号范围广，可以适用于一些小型的工况中，一般在选型的时候，如果我们能够使用三叶罗茨风机，我们不推荐二叶罗茨鼓风机，主要原因是二叶罗茨风机型号较大，能量损耗较高，噪声较大。

The three blade Roots blower is a product derived from the two blade Roots blower. Therefore, the characteristic of the three blade Roots blower is that it has a wide range of models and can be applied to some small operating conditions. Generally, when selecting a three blade Roots blower, if we can use it, we do not recommend the two blade Roots blower. The main reason is that the two blade Roots blower has a larger model, higher energy loss, and higher noise.

不同罗茨风机的特点

Characteristics of Different Roots Fans

随着我国工业的发展，罗茨风机不仅从二叶罗斯风机衍生出来三叶罗茨风机，还有一种叫做扭叶罗茨风机，不管是哪种类型的罗茨风机，其主要的工作原理都是一样的。下面瑞拓风机根据自己的经验来给大家说一下不同罗茨风机各自的特点。

With the development of industry in our country, the Roots blower is not only derived from the two blade Roots blower, but also a type called the twisted blade Roots blower. Regardless of the type of Roots blower, its main working principle is the same. Below, based on my own experience, Ruituo Fan will explain the characteristics of different Roots Fans.

三叶罗茨风机型号范围广，适用工况范围也比较广，不仅可以用于小型的工况中，个别型号也可以用于大型的工况。

The three blade Roots blower has a wide range of models and is suitable for a wide range of operating conditions. It can be used not only in small operating conditions, but also in large operating conditions for individual models.

二叶罗茨风机适用于需求风量较大的环境中，还有一种双极串联罗茨风机是用于对于压力要求较高的环境中。罗茨风机还有一种密集型罗茨风机，密集型风机主要适用于场地面积局限，立体空间足够的环境中。

Two leaf Roots fans are suitable for environments with high air demand, and there is also a bipolar series Roots fan used in environments with high pressure requirements. There is also a type of dense Roots blower, which is mainly suitable for environments with limited site area and sufficient three-dimensional space.
