- Blower Disfunction
- Excessively High Temperature at Outlet
- Excessively High Temperature in Bearings
- Excessively High Temperature in Gears
- Overloaded Current
- Abnormal Noise
(1) Wire defect
(2) Motor breakdown
(3) Foreigh object in cylinder
(4) Idled roter for rusty surface
(5) Foreigh object in grear gaps
(6) Excessive friction in inlet or outlet of blower
Excessively High Temperature at Outlet
(1) Excessively high oil level in gear box
(2) Excessive friction in filter
(3) Excessive pressure difference between imlet and outlet
(4) Rotor gap deviation
Excessively High Temperature in Bearings
(1) Excessively high oil level or excessive grease
(2) Improper viscosity or thickness of oil
(3) Excessively high pressure used
(4) Inlet gas variation
(5) Worn bearing
(6) Partially worn shaft of bearing
(7) Excessive tightness in belt
(8) Affection by rising temperature in roter
Excessively High Temperature in Gears
(1) Excessive or insufficient oil
(2) Improper viscosity or thickness of oil
(3) Excessively high pressure used
(4) Worn gears
(1) Increased resistance at inlet and outlet causing excessive pressure difference between them
(2) Increased blower rotation speed
(3) Motor breakdown
(4) Idled roter for rusty surface
(5) Foreign object in cylinder
(6) Collision between roters
(7) Collision between roter cylinder
(1) Collision between roters
(2) collision between roter and cylinder or side plate
(3) Worn gears or foreign object in gaps
(4) Foreign object in cylinder
(5) Inadequate belt tightness or collision between belt casing
(6) Damaged bearing
