Swirl air pump main fault and solution
It is not difficult to improve the performance of a vortex pump in one area, but it is difficult to increase the performance of the vortex pump in all key performances. From the moment the RHG brand was born, the company has always followed a research and development philosophy: that is, manufacturing a full-featured fan product. We will not sacrifice the fan's performance in other aspects such as energy saving and durability in order to emphasize the high pressure performance of the fan. Therefore, RHG fans are a concentrated expression of high pressure, long life and energy saving.
During the operation of the air pump, some faults may occur. For the generated fault, the cause must be promptly identified and solved in a timely manner to prevent accidents.
The main faults of the air pump are:
1, the bearing box vibration.
solution
A: The fan shaft is not parallel to the motor shaft, and the pulley groove is misaligned.
B: friction between the casing or air inlet and the impeller;
C: The basic stiffness is not enough or not firm;
D: impeller rivet loose or disc deformation;
E: Looseness of impeller disk and shaft;
F: The connection bolts such as the housing and the bracket, the bearing box and the bracket, the bearing box cover and the seat are loosened;
G: poor installation of air inlet and outlet ducts;
H: Rotor imbalance.
2, bearing temperature is too high.
solution
A: The bearing box vibrates violently;
B: Impairment of grease quality, deterioration, dust, sticky sand, dirt and other impurities;
C: The tightness of the bearing box cover and seat connecting bolt is too large or too small;
D: The shaft and the rolling bearing installation are skewed, and the front and rear bearings are not concentric;
E: Damage to rolling bearings.
3, motor current is too high and temperature rise is too high.
solution
A: The valve or throttle valve in the intake pipe is not closed when driving;
B: The flow rate exceeds the specified value, or the air pipe leaks;
C: The fan transport gas density is too large;
D: The motor input voltage is too low or the power supply is single-phase power-off;
E: affected by the vibration of the bearing housing;
F: The fan's working condition deteriorated or it failed.
