(Summary description)There are contaminated impurities on the impeller, causing the gap to be too small; remove the dirt and check whether the internal parts are damaged; the gear is worn, causing large backlash; adjust the gear gap, if the gear backlash is greater than the average 30%~50%, the gear should be replaced ; The gear is not firmly fixed to keep the impeller synchronized; re-assemble the gear to keep the taper contact area up to 75%; the bearing wear causes the clearance to increase, replace the bearing.

(4) Bearing wear causes the clearance to increase. Replace the bearing.

Impeller and casing, wallboard scratch

(1) The installation clearance is incorrect; readjust the clearance;

(2) The operating pressure is too high and exceeds the specified value; find out the cause of the overload, and reduce the pressure to the specified value;

(3) The operating temperature is too high; check the installation accuracy and reduce the pipe tension;

(4) The casing or base is deformed, and the positioning of the fan fails; restore;

(5) The axial positioning of the bearing is not good, check and repair the bearing, and ensure the clearance.
