In most cases, Roots blower conveys clean air. If the temperature of clean air is lower than 40 ℃, the normal operation of the blower can be ensured. Conventional configuration: cast iron, piston ring seal, air cooling can be used.
If the temperature of the gas we transport exceeds 40 ℃, such as saturated steam with high temperature, the requirements for the fan will also be increased, such as stainless steel material, anti-corrosion treatment for the fan, replacement of sealing method, cooling of bearing and oil tank, etc., which requires special treatment before use.
Roots blower can also be used in winter, and can be used in the environment of minus 30 ℃. Pay more attention to the use of roots blower in winter. Low temperature environment and high temperature environment will damage the roots blower, so we should pay more attention to:
1. When Roots blower is used in summer and winter, the inspection density of the blower should be increased from 1 to 2 times a day to 3 to 4 times. In case of failure, the blower should be shut down for inspection.
2. For water-cooled Roots blower, attention shall be paid in winter to prevent the water-cooling pipe from freezing or cracking. When the blower is shut down, the water inside the water-cooling pipe shall be cleaned up.
3. In summer, the inlet air temperature of roots blower is generally controlled below 40 ℃. If the temperature exceeds this temperature, the roots blower may be overheated and the motor may burn.
4. The low temperature in some areas may also be related to altitude. If the altitude is high and the temperature is low, special attention should be paid to the selection of roots blower. The selection cannot be carried out according to normal conditions. Altitude has an impact on air volume and pressure.
5. The general type roots blower is mainly placed above the ground, and the ambient temperature will affect the roots blower and shorten its service life. Therefore, it is better to build a fan room to effectively control the ambient temperature and protect the roots blower.
I believe that after reading the above contents, you should also have an understanding of the mature temperature range of Roots blower. I hope it will be helpful to you.
