A balancing machine is a dynamic balancing equipment used to measure rotor imbalance, which can be divided into hard support and soft support in terms of support structure. A hard support balancing machine can be selected for low speed, internally suspended inner center of gravity rotors. High speed and precision rotors can only be selected with soft support balancing machines. In terms of price, the hard support structure is simple and cost-effective, while the soft support structure is complex and costly. Users must choose a dynamic balancing machine based on their product speed, external geometric dimensions, and dynamic balancing accuracy. Choosing a user-friendly balancing machine for one's own product is crucial, as it directly affects the quality of the product
The balance testing speed of a dynamic balancing machine is closely related to the working speed of the workpiece, but there are many different opinions on the specific relationship. Many people believe that the higher the testing speed of the balancing machine, the better the balance effect of the workpiece, and it can also better reduce negative factors such as vibration and noise; Some people believe that it is best to ensure that the actual working speed of the workpiece rotor is the same as the speed during calibration.
How to select the speed of the dynamic balancing machine for rotor dynamic balance detection; Huake Zhichuang's dynamic balance machine technicians, who have 20 years of experience in the production of dynamic balance testing equipment, have pointed out good suggestions. Below we will share it with everyone for reference only; If you encounter other problems during operation, please contact our technical personnel through the official website phone number in a timely manner to communicate a resolute solution for dynamic balance.
1. Select the appropriate speed based on the working speed of the workpiece
After selecting a suitable dynamic balancing machine equipment, the higher the working speed, the higher the dynamic balancing test speed should be chosen for the workpiece. (Except for workpieces with large static balance, the reasons have been explained earlier) Different workpiece materials and dynamic balance speeds are also different. For example, for special materials such as fans, fans, and other workpieces, or for rotors with plastic impellers, even if the rotational speed is relatively high during operation, there may still be balancing tests that can only be performed at low speeds. Due to the high rotational speed and large imbalance, the workpiece may deform, which seriously affects the accuracy of dynamic balancing tests.
2. Select according to the type of balancing machine
Generally, professional manufacturers choose the testing speed by selecting the type of balancing machine. If a soft support dynamic balancing machine is selected, the testing speed should be higher than the working speed of the rotor. This is because the signal detected by the sensor is proportional to the vibration displacement of the support. If a hard support balancing machine is selected, the testing speed of the balancing machine should be lower than the working speed of the rotor, As the signal detected by the sensor is proportional to the vibration force of the support. But due to the high-speed rotor side with tens of thousands of revolutions, a speed of around 1/10 should be chosen.
3. Select according to the quality of the workpiece
When performing dynamic balance testing on workpieces, the first step is to roughly calculate the weight of the workpiece and find a suitable dynamic balance machine. For heavier workpieces, a suitable hard support balance machine should be selected for testing. Due to the strong rigidity of the hard support balance machine, lighter workpieces should be selected with a suitable soft support balance machine for testing.
4. Choose different test speeds for different diameters
Under normal circumstances, the testing speed is selected based on the principle that the larger the workpiece diameter, the lower the speed. However, even if the diameter of different workpieces is very small, they should be balanced at a low speed when the static balance is too large. As the balance is large, the higher the test speed, the greater the unbalanced centrifugal force generated. It can cause the workpiece to jump on the support frame, and in severe cases, it can cause harm to the human body and also damage the dynamic balance equipment. This requires selecting low speed for balance detection.
There are many factors that we need to consider when selecting a dynamic balancing machine for testing speed. For beginners and balancing machine operators who have just learned the scale of dynamic balancing, in order to quickly and accurately understand the operation and use of dynamic balancing machines, the correct selection of dynamic balancing machines for testing speed is the most concerned issue for many manufacturers and professional technical personnel. The balancing machine process will directly affect the company's production and quality issues.
