Dynamic balancing machine is a precision instrument and equipment with high technical content. We should not only pay attention to workpiece parameters and balancing machine model, but also avoid entering into the wrong selection zone. The following are several common errors that need to be avoided.
1. Balanced Speed and Balanced Precision
Because the dynamic balancer is not well understood, customers usually feel that the higher the balance speed, the better the balance precision. In fact, it is not. A good hard-supported dynamic balancer can correctly detect the magnitude of imbalance at lower speeds, not that the higher the speed, the better the balance precision. For rotors with different mass and shape, different balancing speeds are used to achieve high detection efficiency and precision of the dynamic balancing machine. Generally, the speed of hard-supported dynamic balancing machine is controlled in the range of 200-1500 r/min, which can meet most of the criteria of rotor dynamic balancing. For a soft-supported dynamic balancing machine, there is a certain correlation between balancing speed and balancing precision. Within a certain speed range, there is a linear relationship between balancing speed and balancing precision.
2. Load-bearing mass of rotor and dynamic balancer
During the selection of dynamic balancing machine, the large bearing mass of rotor and dynamic balancing machine are important reference indexes. Rotors of different mass will use dynamic balancing machines of different model specifications. Rotor mass is usually maintained at 25-80% of the larger load-bearing mass of the dynamic balancer. The balancing precision and efficiency of the dynamic balancer are better and its service life is longer.
3. Rotor balance and working state
Some customers feel that the support method for rotor dynamic balancing is the same as that for work, so that the precision of rotor dynamic balancing can meet the working standard. This is mainly due to lack of understanding of the dynamic balancing machine. Dynamic balancing machine is the measurement and correction of unbalance per unit mass of rotor to ensure that the rotor reaches a smaller unbalance within the rotor mass range under the current technical standard of dynamic balancing machine. Rotor dynamic balancing is the adjustment of the unit mass range of the rotor itself. Its precision and balance state are not related. Customers can use the equipment safely by installing the rotor correctly.
4. Operating Speed and Balanced Speed
Some customers feel that the dynamic balancing precision of the rotor will only meet the requirements if the balancing speed reaches the operating speed of the rotor, which is due to the customer's lack of understanding of the concept of balancing speed. Balancing speed: the rotating speed of the dynamic balancing machine when checking the dynamic balance. Under the precondition of ensuring the precision of the rigid rotor, the lower rotating speed should be selected as far as possible, that is, the unbalanced quantity of the rotor can be measured with high efficiency by the dynamic balancing machine at the calibrated balancing speed. The key to the balancing speed is the mass and shape of the rotor. Generally, the larger the mass of the rotor, the lower the balancing speed and there is no relationship with the working speed.
