螺桿鼓風(fēng)機(jī)與空氣懸浮離心鼓風(fēng)機(jī)的對(duì)比

1.螺桿鼓風(fēng)機(jī)與空氣懸浮離心鼓風(fēng)機(jī)都是新興的鼓風(fēng)機(jī)。都是采用永磁變頻電機(jī)，將風(fēng)機(jī)，隔音罩，變頻器等高度集成，對(duì)比各自領(lǐng)域的前輩產(chǎn)品，如羅茨鼓風(fēng)機(jī)，單級(jí)高速、多級(jí)離心風(fēng)機(jī)等，螺桿鼓風(fēng)機(jī)與空氣懸浮鼓風(fēng)機(jī)無疑在技術(shù)以及效率上都有著突出的優(yōu)勢(shì)。

1. Screw blower and air suspension centrifugal blower are new energy saving and environmental protection blowers. They all adopt permanent magnet variable frequency motor, which highly integrates fans, sound insulation covers, frequency converters, etc. compared with the predecessors in their respective fields, such as roots blower, single-stage high-speed, multi-stage centrifugal fan, screw blower and air suspension blower undoubtedly have outstanding advantages in technology and efficiency.

   
   

2.從產(chǎn)品的基本特點(diǎn)上，兩者都是清潔無油的。

2. From the basic characteristics of the products, both are clean and oil-free.

3.螺桿式鼓風(fēng)機(jī)是容積式鼓風(fēng)機(jī)，同樣功率，無法在風(fēng)量上超越離心式的空氣懸浮鼓風(fēng)機(jī)。因此中小型風(fēng)量應(yīng)用場(chǎng)合是螺桿鼓風(fēng)機(jī)的主要應(yīng)用場(chǎng)合，穩(wěn)定，而且可以達(dá)到比較高的壓力。而空氣懸浮鼓風(fēng)機(jī)則可應(yīng)用在單機(jī)大風(fēng)量的應(yīng)用場(chǎng)合。

3. The screw blower is a positive displacement blower, with the same power, it can not surpass the centrifugal air suspension blower in the air volume. Therefore, small and medium air volume applications are the main applications of screw blower, which are efficient and stable, and can achieve relatively high pressure. The air suspension blower can be used in the application of single machine with large air volume.

4.由于是單級(jí)離心式，所以空氣懸浮離心鼓風(fēng)機(jī)在壓力上一般不會(huì)超過1公斤。

4. Due to the single-stage centrifugal type, the pressure of the air suspension centrifugal blower generally does not exceed 1kg.

5.兩者都可以通過變頻實(shí)現(xiàn)參數(shù)調(diào)節(jié)，調(diào)節(jié)的范圍上螺桿鼓風(fēng)機(jī)比空氣懸浮鼓風(fēng)機(jī)更寬。

5. Both of them can be adjusted by frequency conversion, and the adjustment range of screw blower is wider than that of air suspension blower.

6.技術(shù)上，空氣懸浮鼓風(fēng)機(jī)無疑比螺桿鼓風(fēng)機(jī)更為嬌氣，對(duì)工況環(huán)境的質(zhì)量要求很高，灰塵大、濕度高等情況極容易影響設(shè)備運(yùn)行。

6. Technically, the air suspension blower is undoubtedly more delicate than the screw blower. It has high requirements for the quality of the working environment, and it is easy to affect the operation of the equipment in the case of large dust and high humidity.

還有一點(diǎn)就是，雖然空氣懸浮鼓風(fēng)機(jī)運(yùn)行時(shí)沒有機(jī)械摩擦，但是在懸浮軸承啟動(dòng)時(shí)仍存在物理接觸，因此不適合頻繁啟停。而螺桿鼓風(fēng)機(jī)在這幾點(diǎn)上要優(yōu)于前者，不僅適應(yīng)頻繁啟停，同時(shí)對(duì)復(fù)雜惡劣工況的適應(yīng)性也更好。

Another point is that although there is no mechanical friction when the air suspension blower is running, there is still physical contact when the suspension bearing is started, so it is not suitable for frequent start-up and stop. The screw blower is better than the former in these points, which not only adapts to frequent start and stop, but also has better adaptability to complex and harsh conditions.
