2020-11-28
Summary
The operation of the Roots blower is very important. Before starting the machine, please open the manual exhaust valve of the Roots blower to prevent the Roots blower from starting. Check whether the oil in the oil tank has reached the oil level line to prevent damage to the oil shaft. How to use the Roots blower flexibly? If the movement is flexible, please press the start button again, and then slowly close the exhaust valve to make the fan reach full load. When closing, please open the exhaust valve first, and then press OFF. Normal scientific operation may cause minor damage to the machine.

Impeller and impeller scraping
1. There is impurity pollution on the impeller, causing the gap to be too small; remove the dirt and check whether there is damage inside;
2. Gear wear causes large clearance; adjust the gear clearance, if the gear clearance is greater than 30% to 50% of the average value, the gear should be replaced;
3. The gear is not firmly fixed, and the impeller cannot be synchronized; reassemble the gear to maintain the taper, so that the contact area reaches 75%;
4. Bearing wear causes the gap to increase, and replace the bearing.
Impeller and housing, wall panels are scratched
1. The installation gap is incorrect; readjust the gap;
2. The working pressure is too high and exceeds the specified value; the cause of overload is detected and the pressure is reduced to the specified value;
3. The working temperature is too high; check the installation accuracy and reduce the pipeline tension;
4. The shell or base is deformed, and the positioning of the fan is invalid; recovery;
5. The axial positioning of the bearing is not good, please check the bearing and ensure the clearance.
