What's wrong with the high temperature of the outlet pipe of the three leaf Roots blower for sewage treatment?

A few days ago, when Xinqian Shun Fan Editor interacted with friends on the forum, the friend and Xinqian Shun Fan reflected such a problem: how to solve the problem of high outlet temperature of Roots fan? During the conversation with the friend, Xinqian Shun Fan learned that the three leaf Roots fan used by the friend is 49kpa, 3.85m ³/ Min, the netizen told Xinqian Shun Fan Xiaobian that the outlet pipe temperature of the equipment was high, which was hot to the touch. What should we do?

According to this situation, Xinqian Shun Fan asked the friend the following questions:

Is the outlet pipe of Roots blower blocked?

Is there any other abnormal condition of three leaf roots blower?

What is the value on the pressure gauge?

The friend later told the editor that the pressure gauge value of Roots blower was above 0.5, there were no other abnormalities, and the fan pipe was not blocked, because the aeration tank could normally breathe. Later, the netizen reflected another question with Xiao Bian, saying: Is the bacteria in the pool and the large area of death related to the Roots blower?

Xinqian Shun Fan asked: What is the water temperature in your pool? Is there any oil leakage of Roots blower? What are the cooling requirements of high-temperature roots blower?

The netizen responded that the temperature of the pool was about 30 degrees, and there was no oil leakage from the Roots blower. According to the above situation, we can see that there was no fault with the Roots blower, and the death of fungi in the aerobic pool was not much concerned with the Roots blower. Because all indicators of the Roots blower were in a healthy state, Xinqian Shun Fan Xiaobian suggested that he should check from other aspects. Because Xinqian Shun Fan Xiaobian had no other experience in sewage treatment and did not have enough theoretical knowledge, he could only make such suggestions.

Later, Xinqianshun Xiaobian also checked some data and searched some data about the large-scale death of fungi in sewage treatment. Some data mentioned that the PH value of the sewage treatment pool might be abnormal, which caused the fungi unable to survive normally. The specific situation of this netizen needs to be analyzed specifically. Operation Manual of Xinqianshun Roots Blower

As for the abnormal temperature of Roots blower, I have mentioned it many times in the previous articles. Many reasons can lead to the high temperature of the blower, such as bearing damage, impeller friction, pipe blockage, etc. These conditions can lead to the high temperature of Roots blower. You may ask, how is the temperature too high? You can roughly calculate that the 40+pressure rise is about the outlet temperature of the three leaf roots blower, and the maximum temperature of the blower cannot exceed 120 ℃. If such a high temperature exists, it must be checked in time.
