羅茨風機與離心風機的區別

Difference between Roots blower and centrifugal blower

1、工作原理不同,離心風機用的是曲線風葉,靠離心力將氣體甩到機殼處,而羅茨風機用的是兩個8字形的風葉,它們間的間隙很小,靠兩個葉片的擠壓,將氣體擠至出氣口。

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,一般它們的工作壓力不同,羅茨風機的出氣壓力比較高,而離心風機比較小。

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、風量不同,一般羅茨風機用在風量要求不大但壓力要求較高的地方,而離心風機用在壓力要求低,風量要求大的地方。

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、制造精度不一樣,羅茨風機要求的精度很高,對裝配要求也很嚴,而離心風機比較松。當然還有一些小區別就不說了。

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、如果負載需要的是恒流量效果的情況時就用羅茨鼓風機。因為羅茨鼓風機屬于恒流量風機,工作的主參數是風量,輸出的壓力隨管道和負載的變化而變化,風量變化很小。羅茨風機是一種高壓風機,羅茨鼓風機為容積式風機,輸送的風量與轉數成比例,把氣體由吸入的一側輸送到排出的一側。如果負載需要的是恒壓效果的情況時就用離心風機。因為離心風機屬于恒壓風機,工作的主參數是風壓,輸出的風量隨管道和負載的變化而變化,風壓變化不大。離心式風機,風壓力不大??諝獾膲嚎s過程通常是經過幾個工作葉輪(或稱幾級)在離心力的作用下進行的。離心風機屬于平方轉矩特性,而羅茨風機基本屬于恒轉矩特性。

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、羅茨鼓風機一般來說風量比較大,壓力也比較大,同樣羅茨風機噪音也很大,如果需要風量比較小,對噪音要求比較高,就選用回轉式鼓風機,回轉式鼓風機同樣屬于恒流量風機,工作的主參數是風量,輸出的壓力隨管道和負載的變化而變化,風量變化很小,回轉式風機是變容壓縮,其主要特點是:低轉速,低噪音,低振動,效率高,高節能。

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.
