[0001] The utility model belongs to the technical field of high-speed dynamic balance test, and specifically relates to a novel sealer with vibration measurement and oil return functions. Background Art
[0002] Under existing conditions, high-speed dynamic balancing of turbine compressor rotors can reduce the mechanical vibration of the rotors when they are running at high speeds, thereby improving the overall performance of the equipment and is a key factor in ensuring safe operation. Since high-speed dynamic balancing machines are high-end products in the equipment manufacturing industry, the swing frame bearing seat is the core component of the high-speed dynamic balancing machine, and its dynamic characteristics have a direct impact on the accuracy and safety of the high-speed dynamic balancing test. However, the company's existing Schenck high-speed dynamic balancing machine has a vibration probe fixedly installed on the swing frame bearing seat, and the vibration probe cannot be moved. In addition, the vibration data on the swing frame bearing seat indirectly reflects the vibration data of the rotor during operation by monitoring the vibration data of the swing frame bearing shell, and cannot directly monitor the rotor vibration data. At the same time, if the bearing width of the product required by the test is too wide, it will block the oil return of the swing frame bearing seat itself, which cannot meet the actual production needs.
[0003] Therefore, a new sealer with vibration measurement and oil return functions is designed to overcome the above problems. Utility Model Content
