罗茨鼓风机和螺杆鼓风机的区别在什么地方?

罗茨鼓风机和螺杆鼓风机都是属于的风机。但如果两者要进行比较的话，螺杆鼓风机的优势显得更为突出。

Roots blower and screw blower are high efficiency and energy-saving fans. But if the two are to be compared, the advantages of screw blower are more prominent.

因为两者的工作原理不同。罗茨鼓风机在运转和输送空气的过程中，转子间的腔体不发生容积变化，压力来自于把大量的空气强制送入一个体积比较小的外部腔体中，如：管道或储气罐中，外部腔体中空气的密度不断提高，从而产生压力，通常称之为“外压缩”。

Because they work on different principles. In the process of operating and conveying air, the volume of the cavity between the rotors does not change. The pressure comes from forcing a large amount of air into a relatively small external cavity, such as a pipe or an air storage tank. The density of air in the external cavity increases continuously, resulting in pressure, which is usually called "external compression".

而螺杆鼓风机的工作原理就跟罗茨鼓风机有些区别了，空气同样是吸进来，再排出去，吸气时，螺杆和螺杆之间的空腔是较大的，当气体排出去后，腔体容积会变得很小很小，也就是说，在旋转过程中，就相当于把2m³的气压缩成1m³的气，同时，压力就提高到1bar，也就是这个压力的提升不是来自于外围的管网，而是来自于压缩机内部容腔的变化。

The working principle of screw blower is different from that of Roots blower. The air is also sucked in and then discharged. When the air is inhaled, the cavity between the screw and the screw is large. When the gas is discharged, the volume of the cavity will become very small. In other words, in the process of rotation, it is equivalent to reducing the air pressure of 2m ~ 3 to 1m ~ 3, and at the same time, the pressure is increased to 1bar, That is to say, the pressure rise does not come from the peripheral pipe network, but from the change of the internal chamber of the compressor.

由此可见螺杆鼓风机采用内压缩，而罗茨鼓风机采用的是外压缩。内压缩的功耗要远远低于外压缩。

Therefore, screw blower adopts internal compression, while roots blower adopts external compression. The power consumption of internal compression is much lower than that of external compression.
