The Roots blower for sewage aeration has dual functions of aerobic aeration and anaerobic mixing. The blower used in Jiangxi Paper Mill can accelerate the water circulation and remove organic matters that have not been corroded for a long time. It is mainly to reduce the low frequency part of rotating noise. Considering the economy, it is usually used in large sewage treatment plants, while small sewage treatment plants are less used. The belt cover (shield) should be installed on the belt pulley (coupling) to ensure that there is no risk of operation. Will other changes occur after the air passes through Roots blower? Let's talk about it: after the air passes through the Roots blower, no other chemical changes will occur.

羅茨風(fēng)機(jī)選擇的效率還需要根據(jù)葉片形狀和羅茨風(fēng)機(jī)的系數(shù)來(lái)計(jì)算。清潔軸承后更換新油。它可以改善氣壓不足的現(xiàn)象，章丘羅茨鼓風(fēng)機(jī)使氣體燃燒更充分，火力更大。磨損后，它無(wú)法承受負(fù)荷。羅茨風(fēng)機(jī)皮帶長(zhǎng)時(shí)間處于高溫環(huán)境中。自然衰老是正常的。羅茨風(fēng)機(jī)皮帶每年可更換一次。由于該行業(yè)中有機(jī)污染物濃度很高，對(duì)環(huán)境造成了非常大的破壞。

The efficiency of Roots blower selection also needs to be calculated according to the blade shape and the coefficient of Roots blower. Clean the bearing and replace it with new oil. It can improve the phenomenon of insufficient air pressure. The Zhangqiu Roots blower makes the gas burn more fully and has more firepower. After wear, it cannot bear the load. Roots blower belt is in high temperature environment for a long time. Natural aging is normal. Roots blower belt can be replaced once a year. Due to the high concentration of organic pollutants in this industry, it has caused great damage to the environment.

一般情況下，三葉羅茨風(fēng)機(jī)皮帶每年可更換一次。因此，不應(yīng)低估其關(guān)鍵作用。主要判斷是基于潤(rùn)滑脂是否與過(guò)多的硬質(zhì)雜志混合。組裝齒輪部分和油底殼。二氧化硫和氮氧化物的排放量將減少3％，關(guān)鍵區(qū)域細(xì)顆粒物（PM2.5）濃度將繼續(xù)下降，化學(xué)需氧量和氨氮排放量將減少2％，造林面積將超過(guò)1億。需要在空載條件下檢查羅茨風(fēng)機(jī)的轉(zhuǎn)向，以確?？蛰d運(yùn)行，羅茨風(fēng)機(jī)轉(zhuǎn)向錯(cuò)誤，羅茨增氧曝氣風(fēng)機(jī)并且在試運(yùn)行期間不進(jìn)行檢查。

Generally, the three leaf roots blower belt can be replaced once a year. Therefore, its key role should not be underestimated. The main judgment is based on whether the grease is mixed with too many hard magazines. Assemble the gear section and the oil pan. The emissions of sulfur dioxide and nitrogen oxides will be reduced by 3%, the concentration of fine particulate matter (PM2.5) in key areas will continue to decline, the chemical oxygen demand and ammonia nitrogen emissions will be reduced by 2%, and the afforestation area will exceed 100 million mu. It is necessary to check the rotation direction of roots blower under no-load condition to ensure no-load operation. The rotation direction of roots blower is wrong. Roots aeration fan will not be checked during trial operation.
