Problems encountered in the use of the three-leaf Roots blower
Germany AERZEN three-leaf Roots blower is a double impeller synchronous compression machine. Each of the trilobal rotors is supported by two bearings, and the relative positions of the two rotors are always maintained by a pair of synchronizing gears. It is a positive displacement blower with the characteristics of forced air transmission.
The three-leaf Roots blower is widely used in daily life , so we must pay attention to the protection measures . In order to reduce wear and tear during use of the Roots blower, particularly in this case blower to introduce solutions to common problems in daily use in:
Insufficient air volume
1 The impeller and the body cause an increase in clearance due to wear; the replacement method is to replace worn parts.
2 The clearance is loose; the elimination method is adjusted as required.
3 The system has a leak; the exclusion method is to exclude after inspection.
2. The temperature is too high
1 Body part: The static part is rubbed - the method of elimination is to adjust the gap.
2 bearing part:
a, bearing damage - the replacement method is replacement.
b. Too much or insufficient lubricant - the method of elimination is to adjust the amount of oil.
3 lubricant part
a. Gear meshing is abnormal or damaged - the method of adjustment is to adjust or replace after inspection.
b. Bearing damage - the method of replacement is to replace after inspection.
c. Poor oil quality; the method of replacement is to change the lubricating oil.
3. Impact between the impeller and the impeller
1 Gear teeth displacement - the method of adjustment is to adjust the gap and tighten.
2 The tooth surface wear and thus the backlash increases, resulting in a change in the gap between the impellers - the method of adjusting is to adjust the gap.
3 Gear and shaft loosening - the replacement method is to replace the self-locking nut.
4 Main and auxiliary shaft bending overrun - the method of alignment is to straighten or replace the shaft.
5 Incorporating impurities into the body or forming scale due to the medium - the method of removing impurities or scaling is to remove impurities.
6 Rolling bearing wear and clearance increase - the replacement method is replacement.
7 Super rated pressure operation - The method of elimination is to check for the cause of overpressure.
4. The impeller and the casing are radially rubbed
1 Clearance over value - the method of elimination is to adjust the gap.
2 The rolling bearing is worn and the clearance is increased - the replacement method is replacement.
3 Main and auxiliary shaft bending overrun - the method of alignment is to straighten or replace the shaft.
4 Super rated pressure operation - the method of elimination is to check for the cause of overpressure.
