The invention discloses a detection device and a detection method for a mechanical sealing element, belongs to the technical field of sealing elements, and can solve the problem that the leakage amount of a high-pressure mechanical sealing element cannot be accurately detected by existing detection equipment. The detection device comprises a bearing cavity, wherein a first supporting module and a second supporting module are arranged in the bearing cavity; a first to-be-tested sealing element is fixed on the first supporting module, and a second to-be-tested sealing element is fixed on the second supporting module; the first to-be-tested sealing element, the second to-be-tested sealing element, the first supporting module and the second supporting module define a first sealing area; the area except the first sealing area in the bearing cavity is a second sealing area; a rotating module is used for driving the second supporting module to rotate; a first medium module is used for injecting a first medium into the first sealing area; a second medium module is used for injecting a second medium into the second sealing area; and a detection module is used for detecting content information of the second medium in the first sealing area. The device is used for sealing detection of the sealing element.
Description
technical field [0001] The invention relates to a detection device and a detection method of a mechanical seal, belonging to the technical field of seals. Background technique [0002] In the process of offshore oil production and shale oil drilling, it is necessary to use high-pressure mechanical seals (dynamic seals) to replace traditional rubber seals (static seals) to meet the needs of high-pressure dynamic seals. Rubber seals have a certain degree of elasticity and toughness, and are excellent low-pressure sealing materials, but it is difficult to meet the needs of dynamic sealing with relative friction. Existing mechanical seals, especially high-pressure mechanical seals, are generally made of high-hardness materials such as silicon carbide, obtained by sintering, machining, and grinding, and assembled on bearings to achieve mechanical seals during relative motion under high pressure. [0003] Generally speaking, the technical indicators of high-pressure mechanical se...
