Problems solved by technology
[0003] At present, there is no dedicated vibration sensor for marine turbochargers on the market. Ordinary vibration sensors can only detect its vibration state, and the abnormal vibration of turbochargers can be determined only through data extraction and secondary or multiple conversions of vibration signals. In this situation, the hysteresis of fault diagnosis for abnormal vibration of marine turbocharger is too serious, which is an obstacle to the development of ship automation and intelligence
At the same time, the existing sensors need an external power supply to provide energy, and the layout is complicated and inconvenient to install
The abnormal vibration of the existing turbocharger is not easy to locate, and the vibration direction and other conditions are not easy to detect

The invention discloses an abnormal vibration positioning device for the marine turbocharger, which comprises a supporting shell arranged on the outer side of a rotor shaft, the rotor shaft is detachably connected with a shaft sleeve between two bearings, and the inner wall of the supporting shell is detachably connected with an arc-shaped plate and two sets of limiting plates; a radial vibration detection assembly and an axial vibration detection assembly are arranged in the supporting shell. Radial and axial vibration conditions of the rotor shaft are detected through the radial vibration detection assembly and the axial vibration detection assembly, the vibration state of the turbocharger rotor is monitored online in real time, the circumferential position where abnormal vibration occurs is accurately judged according to the change condition of electric signals of the turbocharger rotor, the vibration state of the turbocharger is monitored in a three-dimensional mode, and the problem of serious hysteresis of a traditional vibration sensor on fault diagnosis is solved.
Description
technical field [0001] The invention relates to the technical field of on-line monitoring, in particular to a device for locating abnormal vibration of a marine turbocharger. Background technique [0002] The friction nano power generation technology was officially proposed in 2012. The friction nano power generation technology is used to design the vibration online monitoring device of the marine turbocharger, which breaks through the technical gap of the friction nano power generation technology in the marine turbocharger, and realizes the same Cross-integration and application innovation in the fields of shipbuilding and ocean engineering. [0003] At present, there is no dedicated vibration sensor for marine turbochargers on the market. Ordinary vibration sensors can only detect its vibration state, and the abnormal vibration of turbochargers can be determined only through data extraction and secondary or multiple conversions of vibration signals. The hysteresis of faul...
