Description

Technical Field

[0001] The present application relates to the field of mechanical technology, and in particular to a sealing performance testing device for a kettle mechanical seal. Background Art

[0002] A mechanical seal, also known as a mechanical seal, is a material or part used to fill and prevent leakage between two or more relatively moving surfaces. It refers to a device that prevents fluid leakage and is composed of at least one pair of end faces perpendicular to the axis of rotation that remain in contact and slide relative to each other under the action of fluid pressure, the elastic force of a compensation mechanism, and the cooperation of an auxiliary seal.

[0003] Mechanical seals are important sealing components of mechanical parts, among which the sealing installation of kettle bodies is also widely used. However, it is difficult to test the sealing performance of current mechanical seals after production and processing. After the defective mechanical seals are installed above the kettle body, leakage is prone to occur, which in turn affects the sealing effect of the mechanical seal on the kettle body. Therefore, in order to solve the above problems, we provide a sealing performance test device for mechanical seals for kettles. Utility Model Content
