A static seal leak detection device

Abstract

A static seal leakage detection device, which uses electrical signals to characterize the leakage of the sealing strip. The sealing strip is arranged between the upper cover and the box body, and a sensor composed of several sensors is arranged on the upper end surface of the box body in the contact area of ​​the sealing strip Each sensor includes a positive plate and a negative plate separated by an insulating sheet, wherein each positive plate is connected to the positive pole of an external power supply, and each negative plate is connected to the negative pole of an external power supply. The entire circuit is in an open circuit state under normal non-leakage conditions. When leakage occurs, the conductive liquid medium covers the insulating sheet, and the positive plate and the negative plate are conducted. The device has the advantages of sensitive detection and simple operation.

Description

technical field

[0001] The invention belongs to the technical field of static seal leakage detection, in particular to a static seal leakage detection device, which is suitable for potential leakage risk assessment and leakage detection of sealing strips under conductive liquid media. Background technique

[0002] Static seal refers to a type of seal in which the sealing interface does not slide relative to each other and the joint surface is relatively static. There is usually a seal between the sealing end faces. The seal is soft, has good resilience and followability, and can fill the tiny gaps in the sealing end faces to achieve the sealing effect. However, due to assembly errors, material mechanical properties, external working conditions and other factors, the sealing system will leak the sealing medium. Leakage affects the normal operation of mechanical equipment. Early detection of sealing performance and leakage of seals and assessment of leakage risks of seals can...
