Hydro-electric unit composite material intelligent thrust bearing

Abstract

The invention discloses a hydro-electric unit composite material intelligent thrust bearing. According to the bearing, a single sector thrust bearing shoe is embedded with abrasion sensing elements, a friction sensing element, an oil film temperature sensing element, and an oil film thickness sensing element, and during online monitoring of operation of the thrust bearing, state analyses of friction and abrasion of fluid lubrication and boundary lubrication, and oil film temperature and thickness real-time changes are realized; interconnection and intercommunication with various related information of conventional operation information of the unit such as the work pressure of the bearing shoe, the rotating speed, the shoe body temperature, the oil temperature, the cooling water temperature, the oil change, and the unit vibration etc. are performed, and transmission, storage, personalized analysis and diagnosis of big data can be realized; the implicit demand of difficulties and pain points of a power station can be solved; and safety operation and health maintenance of the unit can be reflected in the following aspects: the unit safety operation standard is defined in a personalized manner, the unit operation health state analysis and diagnosis can be predicted in real time, and the cost is reduced and the benefit is increased for the operation of the power station.

Description

Technical field [0001] The invention relates to the field of bearings, and more specifically to a composite material intelligent thrust bearing of a hydropower unit. Background technique [0002] Elastic metal plastic thrust bearing is a new type of plastic-metal composite bearing in the past two decades. Its products have many outstanding performances. It replaces traditional babbitt alloy bearings in hydropower equipment, mill gearboxes, metallurgical equipment and other industries. Wide range of applications. Although the product has many advanced technical performances, the running status monitoring technology of the product is still relatively backward, especially the use of scientific monitoring technology to dynamically monitor the health status of the bearing bush running, early warning and preventive maintenance and other big data intelligent analysis, It is still in a blank state. [0003] To detect the wear of the elastic metal plastic thrust bearing bush, the prior ar...
