Problems solved by technology

This puts forward strict requirements on the lubrication system. For the sliding bearings of the main helium fan of the high temperature gas-cooled reactor, if the lubrication and cooling cannot meet the requirements, it is easy to cause the bearing bush to burn out, which will cause the abnormality of the entire high-temperature gas-cooled reactor due to the bearing. shutdown

Abstract

The invention relates to a nuclear power sliding bearing oil feeding system based on comprehensive measurement of flow, pressure and temperature. The nuclear power sliding bearing oil feeding system based on the comprehensive measurement of the flow, the pressure and the temperature is used for feeding lubricating oil for a sliding bearing of a nuclear power high temperature gas cooled reactor helium compressor and mainly comprises an oil feeding pipeline, a filtering and cooling pipeline and a sliding bearing lubricating pipeline. The nuclear power sliding bearing oil feeding system based on the comprehensive measurement of the flow, the pressure and the temperature utilizes the comprehensive measurement of the flow, the pressure and the temperature of lubricating oil and utilizes a computer to monitor the pressure and the flow to enable the lubricating oil feeding amount and temperature to meet a working requirement to guarantee the common work of every sliding bearing. The nuclear power sliding bearing oil feeding system based on the comprehensive measurement of the flow, the pressure and the temperature has the advantages of obtaining maximal amount of information by utilizing sensors as less as possible, meeting high reliable requirement of nuclear power system through redundancy configuration, being high in control accuracy, reliable in device operation, safe, simple in system and the like.

Description

technical field [0001] The invention relates to a lubricating oil supply system for sliding bearings used in nuclear power, in particular to an oil supply system for nuclear power sliding bearings based on comprehensive measurement of flow, pressure and temperature. Background technique [0002] The high-temperature gas-cooled reactor is a kind of fourth-generation nuclear reactor. The main helium fan is the "heart" component of the high-temperature gas-cooled reactor. It is a key component to ensure the safety of nuclear power operation and control the circulation of cooling medium. The main helium fan of the high temperature gas-cooled reactor is composed of a volute, an impeller, a drive motor, a support system, a dry gas sealing system and a fan casing. Among them, the impeller shaft needs to be supported by sliding bearings due to its large volume and high rotation speed. Each bearing is composed of 8 bearing pads, which are lubricated by spraying lubricating oil betwee...
