As a kind of engineering machinery, centrifugal pumps are widely used. There are also many contents and knowledge involved in centrifugal pumps, and they are also very complicated. The content that the editor wants to discuss with you is the vibration analysis of the centrifugal pump. Taking the centrifugal pump produced by Wuxi Xinjiuyang Pump Manufacturing Co., Ltd. as an example, the following content is carried out.
Let's first analyze the point that accounts for the largest proportion of vibration problems. The centrifugal pump rotors are unbalanced and misaligned, and the proportion can be as high as 80%. The main reason is that the material structure used by the centrifugal pump is not uniform, and the structure of the parts used is unqualified, resulting in an eccentricity caused by the misalignment of the center line of the rotor mass and the center line of the rotating shaft. Solving this kind of unevenness and misalignment has become the primary task. Generally, static balance and dynamic balance are used for calibration. Secondly, it also includes installation reasons, the foundation bolts are loose, and the level of adjustment is not adjusted. Both need to be strictly inspected before the centrifugal pump is started, to avoid vibrations in the centrifugal pump during work; there are foreign objects in the centrifugal pump It is also one of them, and it is also the focus of inspection before the official start of the centrifugal pump. Finally, there are two more points, that is, the cavitation perforation inside the centrifugal pump and the unreasonable design of the centrifugal pump under long-term working conditions. For example, the size of the equipped parts will also cause the vibration of the centrifugal pump.
The editor's vibration analysis of the centrifugal pump is coming to an end. The points that need to be clarified have been listed in detail. In order to better use the centrifugal pump, it is necessary to control the points summarized above.
