螺杆鼓风机是如何进行工作流程的？

正如螺杆式压缩机是工业界的骨干之一一样，螺杆式鼓风机也已发展成为低压领域的支柱之一。螺杆式鼓风机确实是多面的。即使在恶劣的条件下，它们也可以提供大量的无油空气。

Just as screw compressor is one of the backbones of industry, screw blower has developed into one of the pillars of low pressure field. Screw blowers are really multifaceted. They can provide a lot of oil-free air even in harsh conditions.

由于其设计，通常具有较低的生命周期成本；易于安装；不于在一个应用程序中使用，还可以在多种流程中使用。让我们详细了解螺杆鼓风机的工作原理和优点！

Because of its energy-saving design, it usually has low life cycle cost, easy to install, and can be used not only in one application, but also in a variety of processes. Let's understand the working principle and advantages of screw blower in detail!

它们是如何工作的？

How do they work?

螺杆鼓风机是低压产品系列中相对较新的产品，它是从无油螺杆压缩机技术中开发出来的，并专门针对低压应用进行了优化。与螺杆压缩机类似，螺杆风机结合了公转子和母转子，公转子和母转子旋转并减小它们之间的可用体积，从而导致空气压缩。

Screw blower is a relatively new product in the low-pressure product series. It is developed from the oil-free screw compressor technology and is specially optimized for low-pressure applications. Similar to screw compressors, screw fans combine male and female rotors, which rotate and reduce the available volume between them, resulting in air compression.

通常，它们可以在更大范围的要求下更经济地运行。根据型号和提供者的不同，它们可以达到0.31.5 bar的工作压力。

In general, they can operate more economically under a wider range of requirements. Depending on the model and the supplier, they can reach a working pressure of 0.3 to 1.5 bar.

它们的优点有哪些呢？

What are their advantages?

您知道低压的整个生命周期成本的80％来自能耗吗？那就对了！选择螺杆式鼓风机非常重要，因为它们比传统的叶片式鼓风机30％。此外，螺杆鼓风机可以采用VSD（变速驱动器），从而可以进一步节省能源。这项低压技术还提供了广泛的体积流量和压力，这意味着它们非常适合许多应用。

Do you know that 80% of the life cycle cost of low voltage comes from energy consumption? That's right! It is very important to choose screw blowers because they can save 30% energy than traditional blade blowers. In addition, the screw blower can use VSD (variable speed drive), which can further save energy. This low pressure technology also provides a wide range of volume flow and pressure, which means they are well suited for many applications.
