Reasons and solutions for friction in the impeller of a Roots fan
Roots FansIf friction occurs in the impeller during operation, what are the causes and solutions? Let the Roots Blower team explain.
I. Causes
(1) There are contaminated impurities on the impeller, resulting in too small a gap;
(2) The gears are worn, resulting in a large backlash;
(3) The gears are not securely fastened to keep the impellers synchronized;
(4) Wear of the bearing increases the clearance.
II. Measures to address the problem
(1) Remove dirt and inspect internal parts for damage;
(2) Adjust the gear lash, if the gear side clearance is greater than the average value of 30% ~ 50% should replace the gear;
(3) Reassemble gears to maintain taper Fit contact area to 75%;
(4) Replace the bearings.
