Force display instrument & rotor dynamic balance test
Thank you for your trust. After sending samples for testing, I am very satisfied. After personally verifying at the factory, I will place an order immediately.
Testing achieves quality, quality creates the future, product dynamic balance is good, quality control is also good, not afraid of no orders
The basic working principle of Impeller dynamic balancing machine:
The position of the unbalanced weight of the rotor can only be determined in the rotating state, and the position and size of the balance weight should be determined. This method of finding balance is called the dynamic balance principle. Dynamic balance can not only eliminate the dynamic unbalanced force couple, but also eliminate the static unbalanced centrifugal force, so it can be applied to find the balance of various cylindrical rotors. Such as rotors of centrifugal compressors, rotors of large motors, etc.
The key phase signal and vibration signal of the rotor are measured by the vibration sensor, photoelectric sensor, angle reference signal generator, vector synthesis and other facilities installed on the Jizhi dynamic balancing machine, and the phase and size of the unbalance are calculated through these signals. .
Why do you need to use a dynamic balancer?
Because an unbalanced rotor will generate unbalanced force when it works on the bearing, and will also generate unbalanced centrifugal force. Once the entire unbalanced centrifugal force is large enough to cause vibration on the rotor bearing, it will produce greater noise. And it will accelerate the wear of the bearing, thus affecting the performance and life of the product. Therefore, it is very important to perform dynamic balance correction on the workpiece. The main performance of the balancing machine is expressed by two comprehensive indicators: the minimum achievable residual unbalance and the unbalance reduction rate. The former is the minimum value of the residual unbalance that the balancing machine can make the rotor reach, and it is an index to measure the highest balancing ability of the balancing machine; the latter is the ratio of the unbalanced amount reduced to the initial unbalanced amount after one correction, which is a measure of the balancing efficiency. indicators, generally expressed as a percentage.
According to the needs of mass production, Jizhi Electromechanical can automatically complete the balance measurement and balance correction for specific rotors, as well as the automatic balance machine, as well as the automatic balance line, which greatly improves the production efficiency of the enterprise. In short, the dynamic balance of the rotor includes two steps of unbalance measurement and correction.
