After long-term operation of side channel air blowers generator units, various faults will occur. In order to ensure the normal operation of each equipment, the fault of side channel air blowers generator set should be dealt with in time to ensure the expansion of the fault. How to eliminate the fault of side channel air blowers generator set?
Fuse Burning in Fault of High Pressure Blower Generator Set
(1) Fault causes of side channel air blowers generator set:
(1) The stator and rotor windings are open (one-phase break) or the power supply is out of power in one phase;
(2) Wrong connection at the beginning and end of the winding lead-out wire or reversal connection within the winding;
(3) Loose contacts of power circuit and high contact resistance;
(4) The load of the generator set of side channel air blowers is too large or the rotor is stuck;
(5) The power supply voltage is too low;
_Small side channel air blowers generator assembly is too tight or bearing oil is too hard;
The bearing is stuck.

(2) Fault analysis of side channel air blowers generator set:
(1) Find out the breakpoints and repair them;
Check the polarity of winding and judge whether the end of winding is correct.
(3) Tighten loose connection screw, use multimeter to judge whether the joints are false, and repair them; whether the voltage drop is too large due to too thin power supply wire, and correct them;
(4) Re-assembling to make it flexible; replacing qualified grease;
Bearing Overheating in Fault of High Pressure Blower Generator Set
(1) Fault causes of side channel air blowers generator set:
(1) too much or too little lipid;
(2) The bearing is not properly matched with the journal or end cover (too loose or too tight);
(3) The end cap or bearing cap of side channel air blowers generator set is not installed flat;
(4) The coupling between the generator set and the load of the side channel air blowers is not corrected, or the belt is too tight;
(2) Fault analysis of side channel air blowers generator set:
(1) Add grease (1/3-2/3 of volume) as required;
Replacement of clean lubricating grease;
Over-loosening can be repaired with binder, over-tightening, grinding the inner hole of journal or end cover to make it suitable;
(4) Rectify and adjust the belt tension;
Correction of motor shaft or replacement of rotor.
Abnormal sound of side channel air blowers generator set during fault operation
(1) Fault causes of side channel air blowers generator set:
(1) The rotor rubs against the stator insulation paper or slot wedge;
(2) Bearing wear or foreign matter such as sand in oil;
(3) Loose core of stator and rotor;
Stator winding staggered connection or short circuit.
(2) Fault analysis of side channel air blowers generator set:
Cut the insulation and cut down the slot wedge.
(2) Replacement of bearings or cleaning of bearings;
(3) Inspection and repair of stator and rotor cores;
(4) Eliminate scratches and, if necessary, small rotors in the car;
Eliminate stator winding faults.
