Problems solved by technology

At present, although some national standards or international standards and other documents have clear regulations on the status monitoring of fans, these tests are often only applicable to the production process and factory inspection of fans, which does not guarantee that the fans that have passed the factory inspection are in operation. There will be no abnormality, so it is very necessary to obtain the operating status of the fans of the containment circulating cooling unit

Abstract

The present invention provides a containment circulating cooling unit fan vibration diagnosis apparatus and method. The containment circulating cooling unit fan vibration diagnosis apparatus comprises the a vibration sensor, a vibration characteristic processing unit, a diagnostic management unit, a wireless data interface unit, a standard signal interface unit, an in-containment repeater, an out-containment repeater, and a wireless data receiving and storage server, wherein the vibration sensor, the vibration characteristic processing unit, the diagnostic management unit, the wireless data interface unit, the standard signal interface unit and the in-containment repeater are located in the interior of the containment of the nuclear power plant, and the out-containment repeater and the wireless data receiving and storage server are located outside the containment of the nuclear power plant, the vibration sensor is arranged on a nuclear power plant containment circulating cooling unit fan casing, the vibration sensor vibration is in connection with the vibration characteristic processing unit, the vibration characteristic processing unit is in connection with the diagnostic management unit, and the diagnostic management unit is in connection with the wireless data interface unit and the standard signal interface unit. The containment circulating cooling unit fan vibration diagnosis apparatus reduces the amount of use of cables in the containment, and enhances the flexibility of the diagnostic framework.

Description

technical field [0001] The invention relates to the technical field of nuclear power air-conditioning and ventilation products, in particular to a fan vibration diagnosis system of a containment circulating cooling unit. Background technique [0002] In the air conditioning and ventilation system of nuclear power plants, the fan of the containment circulation cooling unit mainly provides the air circulation function in the containment building of the nuclear power plant, which plays an important role in the safe operation of the nuclear power plant. Due to the high dose of radiation during normal operation of nuclear reactors, operating personnel are generally not allowed to enter. At present, although some national standards or international standards and other documents have clear regulations on the status monitoring of fans, these tests are often only applicable to the production process and factory inspection of fans, which does not guarantee that the fans that have pass...
