Dynamic balancing machine is a precision instrument with high technical content. It is not only important to pay attention to the workpiece parameters and balancing machine model, but also to avoid selection errors. The following are several common misconceptions that need to be avoided.
1. Balance speed and balance precision
Due to a lack of understanding of dynamic balancing machines, customers often feel that the higher the balancing speed used for dynamic balancing, the better the precision of balancing. However, this is not the case. A good hard support dynamic balancing machine can correctly detect the magnitude of imbalance at lower speeds, rather than the higher the speed, the better the balance precision. We will adopt different balancing speeds for rotors of different qualities and shapes to achieve higher detection efficiency and precision of dynamic balancing machines. Under normal circumstances, the speed control of a hard supported dynamic balancing machine is within the range of 200-1500r/min, which can meet the standards for most rotor dynamic balancing; For soft support dynamic balancing machines, 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. The rotor mass and the large load-bearing capacity of the dynamic balancing machine
In the selection process of dynamic balancing machines, the rotor mass and the larger load-bearing capacity of the dynamic balancing machine are important reference indicators. Rotors of different qualities will use dynamic balancing machines of different models and specifications. The rotor mass is usually maintained at 25% to 80% of the larger load-bearing capacity of the dynamic balancing machine. The balancing precision and efficiency of the dynamic balancing machine are good, and the service life is longer.
3. Balance state and working state of the rotor
Some customers feel that the support method for rotor dynamic balancing should be the same as that for working, in order for the precision of rotor dynamic balancing to meet working standards. This is mainly due to insufficient understanding of dynamic balancing machines. A dynamic balancing machine is a measurement and correction of the unbalance within a unit mass of a rotor, ensuring that the rotor reaches the smaller value of the unbalance within the current technical standards of dynamic balancing machines. Dynamic balance of the rotor is an adjustment of the unit mass range of the rotor itself, and its precision is not related to the balance state. Customers only need to correctly install the rotor to use the equipment with confidence.
4. Working speed and balance speed
Some customers feel that the precision of rotor dynamic balancing needs to reach the working speed of the rotor in order to meet the requirements. This is because customers do not have enough understanding of the concept of balancing speed. Balance speed: The speed at which a dynamic balancing machine performs dynamic balancing verification. For rigid rotors, while ensuring precision, a lower speed should be selected as much as possible. That is, the dynamic balancing machine can measure the unbalance of the rotor with higher efficiency at the calibrated balance speed. The size of the balance speed is closely related to the mass, shape, etc. of the rotor. Generally, the larger the rotor mass, the lower the balance speed, and it is not related to the working speed.
