罗茨风机与离心风机的区别

Difference between Roots blower and centrifugal blower

1、工作原理不同,离心风机用的是曲线风叶,靠离心力将气体甩到机壳处,而罗茨风机用的是两个8字形的风叶,它们间的间隙很小,靠两个叶片的挤压,将气体挤至出气口。

1. The working principles are different. The centrifugal fan uses curved blades to throw the gas to the casing by centrifugal force, while the Roots fan uses two 8-shaped blades with a small gap. The gas is squeezed to the air outlet by the extrusion of the two blades.

2、由于工作原理不同,一般它们的工作压力不同,罗茨风机的出气压力比较高,而离心风机比较小。

2. Due to different working principles, their working pressure is generally different. The outlet pressure of Roots fan is relatively high, while that of centrifugal fan is relatively small.

3、风量不同,一般罗茨风机用在风量要求不大但压力要求较高的地方,而离心风机用在压力要求低,风量要求大的地方。

3. The air volume is different. Generally, roots fans are used where the air volume requirements are small but the pressure requirements are high, while centrifugal fans are used where the pressure requirements are low and the air volume requirements are large.

4、制造精度不一样,罗茨风机要求的精度很高,对装配要求也很严,而离心风机比较松。当然还有一些小区别就不说了。

4. The manufacturing accuracy is different. Roots fan requires high accuracy and strict assembly requirements, while centrifugal fan is relatively loose. Of course, there are some communities. Don't stop talking.

5、如果负载需要的是恒流量效果的情况时就用罗茨鼓风机。因为罗茨鼓风机属于恒流量风机,工作的主参数是风量,输出的压力随管道和负载的变化而变化,风量变化很小。罗茨风机是一种高压风机,罗茨鼓风机为容积式风机,输送的风量与转数成比例,把气体由吸入的一侧输送到排出的一侧。如果负载需要的是恒压效果的情况时就用离心风机。因为离心风机属于恒压风机,工作的主参数是风压,输出的风量随管道和负载的变化而变化,风压变化不大。离心式风机,风压力不大。空气的压缩过程通常是经过几个工作叶轮(或称几级)在离心力的作用下进行的。离心风机属于平方转矩特性,而罗茨风机基本属于恒转矩特性。

5. If the load needs constant flow effect, use roots blower. Because roots blower belongs to constant flow fan, the main working parameter is air volume. The output pressure changes with the change of pipeline and load, and the change of air volume is very small. Roots blower is a kind of high-pressure fan. Roots blower is a positive displacement fan. The delivered air volume is proportional to the number of revolutions and transports the gas from the suction side to the discharge side. If the load needs constant pressure effect, use centrifugal fan. Because the centrifugal fan belongs to the constant pressure fan, the main working parameter is the air pressure. The output air volume changes with the change of pipeline and load, and the air pressure changes little. Centrifugal fan with small air pressure. The compression process of air is usually carried out by several working impellers (or stages) under the action of centrifugal force. The centrifugal fan belongs to the square torque characteristic, while the Roots fan basically belongs to the constant torque characteristic.

6、罗茨鼓风机一般来说风量比较大,压力也比较大,同样罗茨风机噪音也很大,如果需要风量比较小,对噪音要求比较高,就选用回转式鼓风机,回转式鼓风机同样属于恒流量风机,工作的主参数是风量,输出的压力随管道和负载的变化而变化,风量变化很小,回转式风机是变容压缩,其主要特点是:低转速,低噪音,低振动,效率高,高节能。

6. Generally speaking, roots blower has large air volume and pressure. Similarly, roots blower has great noise. If the air volume is small and the noise requirements are high, rotary blower is selected. Rotary blower also belongs to constant flow fan. The main working parameter is air volume. The output pressure changes with the change of pipeline and load, and the change of air volume is very small, Rotary fan is variable volume compression, which is mainly characterized by low speed, low noise, low vibration, high efficiency and high energy saving.
