空氣懸浮離心鼓風(fēng)機(jī)的主要部件有空氣懸浮軸承、電機(jī)、變頻器、放空閥等，所有部件整體安裝在普通底座上，其中空氣懸浮軸承是該鼓風(fēng)機(jī)最關(guān)鍵的部件之依靠空氣力場使軸承懸浮、保持高速運(yùn)轉(zhuǎn)，與傳統(tǒng)軸承相比、運(yùn)行時無接觸、無潤滑油、摩擦量小、能量損耗小;采用超高速直流電機(jī)具有無級調(diào)速、調(diào)速范圍寬、結(jié)構(gòu)簡單、噪音低、效率高、運(yùn)行平穩(wěn)等特點(diǎn);通過變頻器調(diào)節(jié)風(fēng)量風(fēng)壓、調(diào)節(jié)范圍廣、精度高，效率提高最大近 30% 以上。總之，空氣懸浮離心鼓風(fēng)機(jī)具有效率高、能耗低、噪音低、安裝簡單、維護(hù)方便等特點(diǎn)

The main components of an air suspension centrifugal blower include air suspension bearings, motors, frequency converters, vent valves, etc., all of which are installed on a common base as a whole. Among them, the air suspension bearings are the most critical components of the blower, relying on the air force field to suspend the bearings and maintain high-speed operation. Compared with traditional bearings, they operate without contact, lubrication oil, friction, and energy loss; The use of ultra high speed DC motors has the characteristics of stepless speed regulation, wide speed range, simple structure, low noise, high efficiency, and smooth operation; By adjusting the air volume and pressure through a frequency converter, the adjustment range is wide and the accuracy is high, resulting in a maximum efficiency improvement of nearly 30% or more. In summary, air suspension centrifugal blowers have the characteristics of high efficiency, low energy consumption, low noise, simple installation, and easy maintenance

Application of 2 Air Suspension Centrifugal Blowers in Wastewater Treatment

在污水處理工藝中，鼓風(fēng)機(jī)主要為好氧生化工藝提供氧氣、維持好氧微生物的生長，其次用于混合攪拌、防止污泥沉淀、使得污染物與微生物進(jìn)一步接觸、去除有機(jī)物，目前，污水處理廠常用的鼓風(fēng)機(jī)有羅茨風(fēng)機(jī)、單機(jī)高速離心鼓風(fēng)機(jī)、空氣懸浮離心鼓風(fēng)機(jī)等，其三種鼓風(fēng)機(jī)性能比較，空氣懸浮離心鼓風(fēng)機(jī)較其他兩種鼓風(fēng)機(jī)效率高、能耗低、調(diào)節(jié)范圍廣、設(shè)備占地小、安裝簡單、維護(hù)方便，在污水處理中具有廣闊的應(yīng)用前景。

In sewage treatment processes, blowers are mainly used to provide oxygen for aerobic biochemical processes and maintain the growth of aerobic microorganisms. They are also used for mixing and stirring, preventing sludge sedimentation, further contact between pollutants and microorganisms, and removing organic matter. Currently, commonly used blowers in sewage treatment plants include Roots blowers, single machine high-speed centrifugal blowers, and air suspension centrifugal blowers. Compared with the other two blowers, air suspension centrifugal blowers have higher efficiency, lower energy consumption, wider adjustment range, smaller equipment footprint, simpler installation, and easier maintenance. They have broad application prospects in sewage treatment.

風(fēng)量調(diào)節(jié)通過轉(zhuǎn)速法和旁路放風(fēng)閥法調(diào)節(jié)風(fēng)量風(fēng)壓，調(diào)節(jié)范圍小通過導(dǎo)葉片角度調(diào)節(jié)風(fēng)量風(fēng)壓，調(diào)節(jié)范圍 45%-100%通過變頻器調(diào)節(jié)風(fēng)量風(fēng)壓。

The air volume and pressure are adjusted through the speed method and bypass vent valve method. The adjustment range is small, and the air volume and pressure are adjusted through the angle of the guide vanes. The adjustment range is 45% -100%, and the air volume and pressure are adjusted through a frequency converter.
