With the arrival of Double 11, various industries have joined the wave of online sales and shopping, and many mechanical manufacturers are also preparing to purchase dynamic balancing machines online. However, purchasing a balancing machine can also be considered a major event for many enterprises, requiring consideration from various factors. Which is the best balance machine and what should I pay attention to when purchasing a dynamic balance machine? The final decision can only be made after repeated comparison and consideration.
Regarding some matters to pay attention to when purchasing balancing machines, the technical master of Huake Zhichuang Dynamic Balancing Machine shares with everyone:
1. Measurement accuracy of dynamic balancing machines
We first need to check the measurement accuracy of the dynamic balancing machine to see if there are any errors, as the measurement errors are very annoying. The connection method between the transmission shaft and the balancing machine and the processing accuracy of the host machine are the main factors that affect the errors.
2. Selection of dynamic balancing machine base
The heavier the base weight of a hard supported balancing machine, the better the quality of the base, and it does not affect the balance accuracy. But it mainly affects the weight loss rate. To achieve the same weight reduction rate, you can use a bulky base or an optional base.
3. The dynamic balancing machine is divided into two support methods
Compared to the soft support and hard support, the swing of the soft support balancing machine is relatively soft. During the start and stop of the drive shaft, the soft supported swing frame will have very obvious vibration, while the hard supported swing frame will not. Among the factors that affect balance accuracy, soft support and hard support are only negligible factors.
4. Characteristics of soft and hard supports
When using a soft support balancing machine, the speed must reach more than three times the resonance speed in order to be detected, so a higher speed is generally used, while a hard support balancing machine must operate at a speed less than three times the resonance speed, so a lower speed is generally used.
5. Excellent measurement system
For a balancing machine, the measurement system is an important point of the entire balancing machine. The design of the mechanical system mainly considers the mechanical characteristics of the unbalanced vibration system, the support method of the rotor, the driving method, and the conversion method between mechanical vibration and electrical quantity.
Strive to convert the imbalance of the rotor into an electrical signal through the sensor without distortion for testing by the measurement system. Due to inevitable mechanical interference, during actual swing vibration, the imbalance not only reflects the main vibration, but also includes various interfering vibrations. In situations where the imbalance is relatively small, this kind of chaotic interference is stronger than the main signal. Therefore, these strong interference signals will measure the weak imbalance signal, so the designed measurement system also needs to have excellent frequency selection and filtering performance.
