Remove vibration from the design, production, and manufacturing stages.
1. A design scheme for a shaft should be based on the resonant frequency of the rotating shaft, bypassing the angular frequency of the motor. Improve the manufacturing quality of the bridge shaft for the nearby cam rotor pump, avoiding quality errors and excessive dimensional tolerances.
2. Select rolling bearings without lubrication.
3. When designing a pump for transporting hot water, the internal stress release system software should be used to release the structural internal stress at the connection caused by the deformation of the cam pump shape. How to deal with problems with cam rotor pumps
Remove vibration during installation and maintenance operations.
1. Before installation, check whether the pump shaft, motor bearings, and rotating shaft have bending deformation or quality errors.
2. Is the spacing between the anchor bolts good? The fusion of the ductile pin and the elastic throwing ring should not be too tight. Is the coupling hole loose in the middle of the shaft? If it is too loose, spraying or other methods should be used to reduce the direct clearance of the coupling to meet the specified specifications. Then fix the coupling firmly on the shaft.
3. Whether the gap value meets the regulations, whether the lubrication in various places is excellent, and whether the maintenance technology level of the pump shaft bearing is improved. Strictly follow the cycle process of first scraping the bearing, then grinding, and then scraping the bearing to ensure that the total contact area between the piston pin and the shaft force meets the required specifications.
4. Timely handle the fatigue situation of components with vibration support points to avoid a decrease in resonance frequency caused by a reduction in compressive strength and bending stiffness.
Moderate clearance of motor bearings is guaranteed, and regular maintenance makes it very easy for parts to be damaged.
The third is to eliminate vibrations caused by the use and incorrect operation of the pump.
The parallel connection of dual pumps should ensure consistent pump performance. When using a cam rotor pump, the performance curve should gradually decrease to good and there should be no camel peaks. To prevent excessive pump vibration amplitude, precise measurement and analysis of vibration conditions can also be carried out to clarify the main parameters of the pump's optimal operation.
