How to verify the accuracy and stability of the balancing machine?
Do all users understand the calibration method of the balancing machine? How to verify the accuracy and stability of the balancing machine? Today, the dynamic balancing machine technician will give you a detailed explanation. At the same time, we welcome friends with technical difficulties and needs in dynamic balancing to contact us through our official website customer service. We can provide on-site dynamic balancing equipment and on-site dynamic balancing testing services.
In the calibration standards for dynamic balancing machines, detailed instructions are provided for the calibration of general dynamic balancing machines, while for the calibration of specialized dynamic balancing machines, it is required to refer to the calibration of general dynamic balancing machines. With the widespread use of dynamic balancing machines, especially the emergence of a large number of specialized balancing machines, their calibration is obviously unreliable. So, based on the principle of dynamic balancing and the method of universal dynamic balancing machine calibration, we should grasp the core of balancing machine calibration. The minimum achievable residual unbalance e0 and the unbalance reduction rate URR can be tested by first measuring the minimum achievable residual unbalance of the balancing machine, and then calculating the verified test weight based on this result, and then verifying whether the minimum achievable residual unbalance of the balancing machine is qualified. Determine the unbalance reduction rate of the balancing machine using the circular chart method, and obtain the accuracy of the balancing machine's orientation indication.
What are the key indicators of a balancing machine?
1. Accuracy of balancing machine: The so-called balancing machine accuracy refers to the minimum measurement unit that the balancing machine itself can achieve based on the size requirements of the workpiece, generally expressed in units of g · mm/Kg. The smaller the value before the unit, the higher the accuracy that the equipment can achieve, and vice versa.
2. The first reduction rate of the unbalance amount of the balancing machine: When the residual unbalance amount of the workpiece measured by the balancing machine is reduced or increased by the displayed value using the method of weight removal or weighting. After checking the actual reduction of the residual unbalance amount after adding or subtracting weight, the percentage of the actual reduction value to the displayed unbalance amount is the first reduction rate. The larger the reduction rate, the better the equipment, and vice versa.
3. Re linearity of balancing machine (also known as: re linearity): When the residual unbalance of the workpiece is measured on the balancing machine, no action is taken. After repeating the measurement N times, the difference between each value is compared. The smaller the difference, the better the re linearity of the balance, and vice versa.
4. Linearity of a balancing machine: The maximum deviation (Δ Ymax) between the calibration curve of the balancing machine and the actual straight line under specified conditions, expressed as a percentage of the full-scale output (Y), is called linearity (also known as "non-linear error"). The smaller the value, the better the linearity. It may also be explained that the balancing machine establishes parameters for each specific test weight before testing a certain workpiece, so when using other test weights, it can reflect the authenticity of its test weight, which is called linearity.
5. Accuracy of balancing machine: the authenticity of the unbalance value that can be measured by the balancing machine.
6. The production characteristics of the balancing machine: When measuring workpieces, the balancing machine requires the workpiece to be clamped or placed on a support frame. After each measurement, the workpiece does not make any correction action, and the workpiece is removed from the equipment and put back into the measurement again.
7. The production efficiency of a balancing machine is the ratio of the actual output of qualified products to the testing unit time within a specified workpiece time. It can reflect the maximum output achieved. Measurable performance of economic entities under targets such as output, cost, income, or profit.
