A static ring device for axial end face sealing

Abstract

The invention provides an axial end-surface sealing static ring device which comprises a static ring, a static ring seat and a magnet induction temperature detecting assembly, wherein the static ringseat is used for fixing the static ring; the magnet induction temperature detecting assembly is used for detecting the temperature of a sealing surface of the static ring; micro grooves are formed inthe sealing surface of the static ring; the magnet induction temperature detecting assembly comprises a permanent magnet arranged on the static ring as well as a temperature detecting and sensing assembly arranged on the static ring seat; and the temperature detecting and sensing assembly is used for detecting the variation of a magnetic field of the permanent magnet when the temperature of the sealing surface of the static ring varies. By adoption of the axial end-surface sealing static ring device provided by the invention, the problem that the lubricating sate of the sealing surface of thestatic ring is frequently switched can be solved; the sealing operation stability and reliability can be improved; and the temperature of the sealing surface of the static ring can be detected. When the lubricating state of the mechanical end surface is obviously improved as well as the sealing operation stability and reliability are improved, the problems that a conventional temperature detectingmethod for mechanical sealing is difficult to promote in engineering application as well as the dismounting, the replacement and the reuse are difficult can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of mechanical seals, and in particular relates to an axial end face seal static ring device. Background technique [0002] With the rapid development of modern industry, mechanical sealing technology has become increasingly complex, precise, efficient and intelligent, and has been widely used in major fields such as petroleum, chemical industry, electric power, metallurgy, papermaking, food, nuclear power, shipbuilding, aviation, aerospace and military industry . As a key basic technology and key basic component of rotating equipment in various major fields to prevent process medium or lubricating oil leakage, save energy and control environmental pollution, the quality and performance of mechanical seals directly determine the operating cycle and efficiency of supporting equipment. [0003] During the operation and service of the mechanical seal, when the operating conditions are abnormal or fluctuate grea...

AI Technical Summary

Problems solved by technology

The reason is: on the one hand, it is very difficult to install the wired thermocouple sensor in the millimeter space between the rotating shaft and the sealing ring; on the other hand, although the wired thermocouple is installed on the static ring body that has been designed and processed , but it must be fixed by high-temperature adhesive, because the principle of temperature measurement is based on the connection of thermocouple and transmission line and the overall structure of the mechanical seal assembly, when the mechanical seal is inspected and maintained, it is difficult to disassemble and replace the wired thermocouple sensor and it is difficult to repeat The use of this method makes it difficult to promote the method in engineering applications
