(Summary description)In mechanical operation, the safety and stability of the equipment and workpieces we use mainly depends on whether there is vibration, and the vibration is mainly caused by the imbalance of the shaft system. The on-site high-speed dynamic balancing machine of the turbine generator set is an effective solution to solve the vibration of the unit. Let’s take a look with Shanghai Shenke Dynamic Balancing Machine Manufacturing Co., Ltd. We can operate according to the vibration principle of the flexible rotor. Before performing dynamic balancing, it is very important to determine whether the vibration mode of the rotor unbalance is the first, second or third order. When the generator rotor works at the second-order critical speed, the unbalance of the protruding end will deform the second-order vibration mode of the main span rotor, resulting in vibration characteristics similar to the third-order unbalance of the main rotor. Span rotor. Practice shows that compared with other forms of vibration, it is sometimes difficult to reduce in-phase vibration. We can use the Bode plot to perform modal analysis on the rotor to determine whether the unbalance is in the same direction or in the opposite direction, whether it is within the span or outside the span, and can be solved by adding weight. Formulating a dynamic balance weighting plan is a more critical step. The on-site dynamic balance is based on the raw data obtained. There may be many weighting schemes, and we need to choose carefully. We should first ensure that the number of startups we focus on is reduced. Secondly, in order to make the residual vibration relatively small, we should have more understanding of the aggravation process and measurement results, and reduce the risk to a very low level. Only in this way can the correct plan be implemented. The operation steps of the on-site dynamic balancing machine of the steam turbine generator set: 1. Develop a feasible weighting plan for the dynamic balancing machine and determine the weighting operation steps. 2. Try to add weight and measure weight data. This step is not necessary. 3. Analyze and record the measured vibration data. 4. Formally aggravated. The above is the relevant introduction of Shanghai Shenke Dynamic Balancing Machine Manufacturing Co., Ltd. on the operation of the on-site dynamic balancing machine of the steam turbine generator set.
