With the continuous improvement of our comprehensive national strength and great changes in people's living standards, more and more rotor manufacturers will purchase one or more dynamic balancing machines to improve rotor quality. Whether to choose a universal balancer with affordable prices or a fully automatic balancer with convenient operation confuses many users. The selection of dynamic balancing machine can be considered comprehensively from price range, accuracy, measuring efficiency and operation, quality and durable failure rate. The dynamic balancing machine suitable for its own products is the best one.
What do you need to know and consider in advance to purchase a dynamic balancer? Huake Zhichuang Balancer Technician analyses four misunderstandings in choosing and purchasing a balancer for you:
1. Balanced Speed and Balanced Precision
When it comes to the speed and precision of a dynamic balancer, many customers don't know enough about it. They usually feel that the higher the balance speed, the better the balance precision, but they don't. A good hard-supported dynamic balancer (dynamic balancer of rigid swing frame) can correctly detect the magnitude of imbalance at lower speed, but not 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. Large 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 state 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
After collecting and sorting out the customer's opinions and suggestions, some customers feel that the dynamic balance precision of the rotor will meet the requirements only if the balancing speed reaches the working speed of the rotor, which is mainly due to the customer's unclear 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.
If you are still considering what to do with the universal balancer and the automatic balancer, they have their own characteristics. First, the automatic balancer measures more efficiently and saves more labor. However, the disadvantage is that the access and versatility of the automatic balancer correction are not as great as that of the manual balancer. So depending on the actual rotor and output, it is best to choose the right one for your needs.
