Abstract

The utility model provides a monitoring of rotor vibration state and failure analysis system based on current vortex sensor which characterized in that: including monitoring module and analysis module, the monitoring module includes input unit and acquisition unit, analysis module includes network switching unit, main control board unit, the main control board unit pass through the network switching unit with the monitoring module links to each other, the main control board unit even has ethernet, RS232 interface, network switching unit, main control board unit, ethernet, RS232 interface integration set up on the mainboard, still include power module, power module links to each other with monitoring module, analysis module. Compared with the prior art, the utility model discloses monitoring of large -scale rotor vibration state and failure analysis protect function can be realized perfectly to simple structure, measurement accuracy height.

Description

A kind of rotor oscillation status monitoring based on current vortex sensor and trouble analysis system

Technical field

This utility model belongs to technology of instrument and meter field, relates to a kind of monitor controller, particularly to a kind of large rotor Vibration Condition Monitoring and accident analysis protection system.

Background technology

Along with increase in demand and the supply and demand growing tension of the energy, the industry development such as thermoelectricity, water power, wind-powered electricity generation is rapid, and installed capacity constantly rises；Along with the equipment automatization detection technique such as chemical industry, metallurgy industry improves day by day, for ensureing equipment safe and reliable operation and the requirement of maintenance, need to research and develop large rotor Vibration Condition Monitoring and accident analysis protection system and correlation technique.According to imperfect statistics, annual domestic present situation enterprise reaches hundreds of hundred million yuan from external import similar products.

Manufacture this series products in the world based on U.S.'s Bentley (BENTLY) company, its technology represents current international most advanced level, its product accounts for more than the 70% of China market, in addition with Germany philips(epro), Japan shikawa etc., what wherein overall technique performance was the highest works as Bentley (BENTLY) company of the number U.S..

At present, domestic also have some universities and colleges, institute and sensor producer to have ultra-low temperature drift performance, strong interference immunity in research and development, has the current vortex sensor of the high linearity and degree of accuracy, such as the QH8500 series current vortex sensor of certain university, temperature drift coefficient index is 0.05v/ DEG C；The KY8500 series of products of Hefei ,Anhui Sensitive Object, temperature drift coefficient index is ± 0.1v/ DEG C etc., these products can only independently become system, exchange poor performance, more can not carry out parts with external product and exchange compatibility, owing to product exists so many limitation, the demand of industry spot automaticity can not be met far away.

Such Low Drift Temperature current vortex sensor product of China relies primarily on import, and within 2007, BENTLY company of U.S. non-contact electric eddy sensor is 2,400,000,000 dollars in the sales volume of China.Therefore, one, domestic in the urgent need to setting up the ultra-low temperature drift contactless vibrating/displacement sensor of high accuracy the theory and technology of energy parts import substitutes parts completely, exploitation has the ultra-low temperature drift contactless vibrating/displacement sensor of high accuracy of independent intellectual property right, its two, domestic in the urgent need to research and development have independent intellectual property right large rotor vibrational state intelligent configuration monitoring, trouble analysis system.Current domestic large rotor Vibration Condition Monitoring, trouble analysis system almost dependence on import, the domestic dynamic trait research to large rotor is the most deep, but on-the-spot Vibration Monitoring, Analyzing and trouble analysis system are realized Technical investment research not, is also badly in need of exploitation and there is the large rotor vibrational state intelligent configuration monitoring of independent intellectual property right, trouble analysis system software and corresponding system platform.
