We all know that one of the most troublesome problems of Explosion proof motor housing is noise. During use, Explosion proof motor housing will produce certain friction with the motor, which will produce varying degrees of mechanical noise, mainly reflected in the noise caused by rotor imbalance and eccentric parts, So how can we reduce the noise generated by Explosion proof motor housing.
1. Strictly control the assembly process. Demagnetization and cleaning procedures are very important to remove residual oil and iron filings;
2. Use sealed bearings to prevent sundries from entering; The fit between the bearing outer ring and the bearing cavity and the fit between the inner ring and the shaft shall not be too tight;
3. In order to eliminate the axial clearance of the rotor, appropriate pressure must be applied to the bearing; Reasonably equipped with sealing elastic gasket and appropriate lubricant to reduce friction;
4. For Explosion proof motor housing with special noise requirements, low noise bearings shall be used; When the load is not too large, oil bearing can be used.
