Abstract

The invention discloses a fan gearbox working condition detection and fault diagnosis system which comprises a temperature sensor, a vibration sensor, a noise sensor, a signal preprocessing card, a signal acquiring card, a programmable logic controller (PLC) and an industrial personal computer. The fan gearbox working condition detection and fault diagnosis system performs condition monitoring on operating characteristics of a gearbox, performs monitoring and recording at regular intervals, finds hidden dangers in time, can find out reasons leading to problems, and adopts measures correspondingly to solve the problems.

Description

technical field [0001] The invention belongs to the field of fan state detection, and in particular relates to a working state detection and fault diagnosis system of a fan gearbox. Background technique [0002] Judging from the current faults of the wind turbine gearbox, the damage of gears and bearing components mainly includes several types of wear: adhesive wear, corrosion wear, surface fatigue wear, fretting wear and cavitation. After these wears occur, the metal particles will pollute the lubricant, affect the power transmission, generate noise, cause serious wear or fracture of the tooth surface, damage the inner and outer rings of the bearing or balls, and seriously make the unit unable to rotate and stop completely. Therefore, a kind of Working state detection and fault diagnosis system of wind turbine gearbox. Contents of the invention [0003] The purpose of the present invention is to provide a working state detection and fault diagnosis system of a wind turbi...
