A common sense discourse on roots blowers

1. The varieties of roots blowers can be divided according to the shape of the rotor, and the roots blowers can be divided into two types: double-lobe type and three-lobe type.

2. Characteristics of roots blower The advantages of roots blower are: wide pressure selection range, simple structure, convenient maintenance and long service life; When the fan is running, the oscillation is small, and it can be used in series with multiple stages. However, its disadvantage is that it is noisy and easy to leak during operation.

3. The conveying medium of the roots blower is clean air, coal gas, sulfur dioxide and other inert gases or special gases.

4. The operation of the roots blower clarifies that the inlet temperature of the conveying medium should not exceed 40°C and the particle content should not exceed 100 mg/m³. When the blower is running, the bearing temperature should not exceed 95°C, and the lubricating oil temperature should not exceed 65°C. The applied pressure must not be higher than the value specified on the nameplate. There is also the oil level, which should be between the two red lines of the oil level gauge. If it is below the red line, it should be compensated.

5. The protective lubricating oil of roots blower should be changed every 3 to 6 months. The muffler should be overhauled every six months or so, and some or all of the sound-absorbing materials should be replaced. The air filter should be checked frequently, and if there is a blockage, it should be dredged in time. Pipes and valves should be unobstructed, and working conditions should be prominent.
