The dynamic balance detection of a horizontal multi-stage pump refers to the method of connecting the impeller to the chuck and balancing it on a balancing machine. The quality and centrifugal force parameters of the impeller are detected, and the balance is achieved by adjusting the shape of the impeller or adding a balance block to ensure the balance of the water pump impeller. Next, we will explain why the rotor of a horizontal multi-stage pump needs dynamic balance detection.
1. Detecting balance
Due to the manufacturing and assembly processes of the rotor, the final assembled rotor always cannot achieve complete axial symmetry in terms of power (known as shaft eccentricity), resulting in a certain degree of imbalance.
2. Determine the accuracy of the workpiece
Usually, by knowing the diameter, weight, working speed, and balance accuracy level of the workpiece, the balance accuracy of the workpiece can be determined. It is important to have a thorough understanding of the balance accuracy of the workpiece.
3. Extend service life
In order to ensure better operation of rotor components, improve their performance, enhance product quality, and extend their service life, dynamic balancing tests should be conducted during the manufacturing process.
4. Avoid vibration
For rotors of a certain shape and size, the center of gravity of the rotor is moved to the axis of rotation using the method of weighting or de weighting, so that the rotor can operate stably under the action of inertial force without significant vibration during rotation.
5. Reduce energy loss
Eliminating the centrifugal force generated during the rotation of the rotor components of a horizontal multi-stage pump can maintain the normal operation of the pump and reduce vibration and energy loss.
6. Eliminate or reduce the adverse effects of inertial forces
When the magnitude and direction of inertial force change periodically, the machine will produce vibration and noise. Therefore, in high-speed, heavy-duty, and precision machinery, in order to eliminate or reduce the adverse effects of inertial force, it is necessary to balance the rotor.
In summary, the above is the relevant content introduced to users about why the rotor of a horizontal multi-stage pump needs dynamic balance testing.
