The factors affecting the outlet temperature of Roots blower include: the volume efficiency of the fan, the working pressure, the internal leakage of the fan and the temperature of the suction air. The high temperature of Roots blower is an abnormal phenomenon, which has many adverse effects on the blower itself and even stops the whole system. How to avoid excessive fan temperature can be started from the following aspects:

管道。管道壓力是一個更容易導致風扇溫度過高的因素,。根據(jù)不同口徑,，將出風口的主管道固定。如果人為改變管道的特殊要求,，容易引起翻滾,。養(yǎng)殖往往容易出現(xiàn)主管道的情況。將修改主管道直徑,。相應的處理可以保證風機的正常壓力,。

The Conduit. Pipe pressure is a factor that is more likely to cause excessive fan temperature. Fix the main pipe of the air outlet according to different diameters. If the special requirements of the pipeline are changed artificially, it is easy to cause rollover. The main pipeline is often easy to occur in aquaculture. The main pipe diameter is modified. The corresponding treatment can ensure the normal pressure of the fan.

二是工作環(huán)境。按照正常的設計標準,，風機是在風機泵房內(nèi)運行的,，但根據(jù)筆者多年的經(jīng)驗，羅茨風機大多是在露天環(huán)境下運行的,。夏季環(huán)境因素的影響更為明顯,。在有條件的場所，可配置冷卻和冷卻設備,，以避免環(huán)境因素對風機的影響,，或配備帶散熱器的隔音罩。

The second is the working environment. According to the normal design standard, the fans are operated in the fan pump room, but according to the author's experience for many years, Roots fans are mostly operated in the open air. The impact of environmental factors in summer is more obvious. In places with conditions, cooling and cooling equipment can be configured to avoid the impact of environmental factors on the fan, or the soundproof cover with radiator can be equipped.

三是風扇的配置,。風力機的壓力是恒定的,，但經(jīng)常有小型馬車，也就是有大型風扇的小型馬達,。為了滿足風機的流量要求,，風機會對電機造成較大的負荷，從而導致電機燃燒,，風機發(fā)熱,。

The third is the fan configuration. The pressure of the wind turbine is constant, but there are often small carriages, that is, small motors with large fans. In order to meet the flow requirements of the fan, the fan will cause a large load on the motor, resulting in motor combustion and fan heating.

四是風機的安裝。如果使用新風扇時，流動壓力沒有問題,，它不會過載或熱,，但會在一段時間后開始燃燒，表明風扇需要重新檢查皮帶的密封性并重新擰緊固定螺釘,。

The fourth is the installation of fans. If there is no problem with the flow pressure when using a new fan, it will not be overloaded or hot, but will start to burn after a period of time, indicating that the fan needs to recheck the tightness of the belt and retighten the fixing screws.
