In our daily work, the imbalance caused by the workpiece in the production process is the main problem causing the product failure. Because it needs to be corrected by the dynamic balancing machine, in fact, we generally do not understand the balancing machine, then the balancing machine is How to verify, let's take a brief look at it.
The two main precision indicators of the balance machine: the minimum reachable residual unbalance and the unbalance reduction rate. Whether it is a horizontal balance machine or a vertical balance machine, double-sided correction or single-sided correction, it should be standardized by standard regulations. Check the rotor and method steps for new product identification and batch product pre-shipment measurements.
The quality of the verification rotor should be less than 1/3 of the mass range of the workpiece allowed by the balancer. For the soft-bearing balancer, the dynamic balance measurement of the rotor is performed while using the lower limit of the mass range of the workpiece allowed by the balancer. The balancing force of the balancing machine within the mass range of the workpiece produced by the quality of the workpiece has a significant effect on the test results.
The test speed is a low speed specified by the manufacturer for the quality of the selected check rotor. If the manufacturer and the user agree, the higher speed specified for the heavier rotor may be selected.
Then for the vertical balancer with single-sided verification, it is also necessary to verify the unbalanced force-to-interference ratio. For horizontal balancing machines that can be used for out-balance rotor balancing, a combined overhanging verification rotor is also required for verification of the above two accuracy indicators.
