With the arrival of Double 11, various industries have joined the wave of online sales and shopping, and many machinery manufacturers are also preparing to purchase dynamic balancing machines online. However, purchasing a balancing machine is also a big deal for many businesses, requiring consideration from various factors. Which is a good balancing machine and what should be noted when purchasing a dynamic balancing machine? A final decision can only be made after repeated comparison and consideration.

Which is a good balance machine

Regarding some matters to pay attention to when purchasing a balancing machine, the technical master of Huake Zhichuang Dynamic Balancing Machine shares with everyone:

1. Measurement accuracy of dynamic balancing machine

We first need to check the measurement accuracy of the dynamic balancing machine to see if there are any errors, because the measurement errors are very annoying. The connection method between the transmission shaft and the balancing machine and the machining accuracy of the host machine are the main factors affecting the errors.

2. Selection of Base for Dynamic Balancing Machine

The heavier the weight of the hard support balancing machine base, the better the quality of the base, and it does not affect the balancing accuracy. But it mainly affects the weight loss rate. To achieve the same weight loss rate, you can use a bulky base or an optional base.

3. The dynamic balancing machine is divided into two types of support methods

Compared with soft support and hard support, the swing of a soft support balancing machine is relatively soft. During the start and stop of the drive shaft, the soft supported swing frame will have very noticeable vibrations, while the hard supported swing frame will not. Among the factors that affect balance accuracy, soft and hard supports are only one that can be ignored.

4. Characteristics of soft and hard supports

When using a soft support balancing machine, the speed must reach at least three times the resonance speed in order to detect it, so a higher speed is generally used, while a hard support balancing machine must work 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 electricity.

We strive to convert the unbalance of the rotor into an electrical signal through sensors without distortion, for testing by the measurement system. Due to inevitable mechanical interference, during actual swing frame vibration, the unbalance also includes various interfering vibrations in addition to the main vibration. Since it is in situations where the imbalance is small, this kind of chaotic interference is stronger than the main signal, so these strong interference signals will measure the weak imbalance signal. Therefore, the designed measurement system also needs to have excellent frequency selection filtering performance.
