Problems solved by technology

The disadvantage of the existing technology is that it is not possible to track and detect the deformation of the preloaded disc spring (including deformation and creep under working conditions)
At present, most power plants use double-ear stop gaskets, which are difficult and time-consuming to replace.

Embodiment Construction

[0032] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0033] figure 1 It shows the disc spring online monitoring system in some embodiments of the present invention, which is used for online monitoring and early warning of the disc spring 1, specifically for the precise monitoring of the deformation of the disc spring 1, and through technical conversion, to issue the sealing force of the equipment Insufficient early warning and early warning that the deformation of the disc spring 1 is about to exceed the design requirements. The background control room will perform human intervention after receiving the early warning signal, which can better ensure the sealing performance and safety function of the equipment. At the same time, it can provide long-term monitoring data under...

Abstract

The invention discloses a disc spring online monitoring system and method. The system comprises a disc spring, a bearing surface, a columnar fastener and a deformation monitoring assembly, wherein the bearing surface bears the disc spring and the fastener, and the fastener is arranged in a connecting hole in a penetrating manner; the disc spring sleeves the periphery of the fastener; the deformation monitoring assembly comprises a deformation acquisition module for acquiring deformation data of the disc spring; the signal transmission module transmits deformation data; the sealing judgment module selectively outputs a sealing early warning signal according to the deformation data; and the service life judgment module selectively outputs a service life early warning signal according to the deformation data. According to the disc spring online monitoring system and method, the sealing force and the service life of the disc spring are judged through the sealing judgment module and the service life judgment module according to the deformation data, a sealing early warning signal is sent out when the sealing force is insufficient, and a service life early warning signal is output when the deformation amount of the disc spring exceeds the design requirement for human intervention of workers; and the sealing performance and the safety function of equipment can be better ensured.

Description

technical field [0001] The invention relates to the field of fastener loosening monitoring, in particular to an online monitoring system and method for disc springs. Background technique [0002] In the prior art, shaft torque monitoring or screw tension is often used to judge bolt looseness. The disadvantage of the prior art is that it is not possible to track and detect the deformation of the preloaded disc spring (including deformation and creep under working conditions). At present, most power plants use double-ear stop gaskets, which are difficult and time-consuming to replace. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved disc spring online monitoring system and method for the above defects. [0004] The technical solution adopted by the present invention to solve the technical problem is to provide an online monitoring system for disc springs, including disc springs, supporting surfaces, co...
