What are the faults caused by subdividing blower Roller Bearing damage?
After the high-pressure blower is used for a period of time or when it is used improperly, some failures may occur, such as the fierce vibration of the bearing housing, the temperature rise of the bearing is too high, the electromechanical electron flow is too large, and the temperature rise is too high. To deal with these faults, it is necessary to know the faults caused by these faults. The reasons listed below are the possible causes of these failures.
(1) The bearing box is fiercely vibrating
1: The fan shaft and the motor shaft are not lateral, and the conveyor belt groove is misaligned;
2: the casing or the air inlet is rubbed with the impeller;
3: the stiffness of the root is not enough or not solid;
4: The impeller rivet is loose or the disc changes the status quo;
5: The leaf axle plate and the shaft are loose;
6: The connecting screw of the casing and the shelf, the bearing box and the shelf, the bearing box cover and the seat are loose;
7: The device for entering the air passage of the fan is not good;
8: The high pressure blower rotor is not balanced.
(2) Bearing temperature rise is too high
1: The bearing housing trembles fiercely;
2: The quality of moisturizing oil is not good, the taste is good, and it contains impurities such as dust, sand, and misunderstanding;
3: The bearing force of the bearing box cover and the seat connecting screw is too large or too small;
4: The shaft and the rolling bearing device are inclined, and the bearing core difference is successively;
5: High pressure blower rolling egg bearing damage.
(3) Electromechanical electron flow is too large and temperature rise is too high
1: The valve or throttle valve in the intake pipe is not closed when starting up;
2: The scalar exceeds the limit value, or the air duct leaks;
3: The fan transport gas is too fine;
4: The motor input voltage is too low or the power supply is single-phase powered off;
5: affected by the intense vibration of the bearing housing;
6: The working condition of the fan has deteriorated.
After understanding the possible causes of the failure, we can make us more targeted during the inspection, especially for those who are not very familiar with the high pressure blower. It is helpful to see the cause of the failure at a glance.
