Problems solved by technology
The detection of the dynamic seal at the present stage is to fit the dynamic ring and the static ring together before the assembly test, and perform an air-tight inspection after applying torque to the two. In this case, it is impossible to simulate the elasticity of springs and wave rings in actual working conditions. The influence of components on the sealing effect, the test effect has a certain degree of unreality

The invention relates to a portable mechanical dynamic seal air-tight test device. The structure of the portable mechanical dynamic seal air-tight test device is as follows: a socket sleeves the outside of a rotor, one end of the rotor is connected with an impeller, a moving ring, a stationary ring and a shell are sequentially arranged at the other end of the rotor; a seal ring I is arranged between the moving ring and the rotor, a seal ring II is arranged between the stationary ring and the shell, a seal ring III is arranged between the shell and the rotor, and a limiting spring is arranged between the shell and the stationary ring. The portable mechanical dynamic seal air-tight test device realizes uniformity of test conditions and practice working conditions in mechanical dynamic seal tests and simultaneously meets the requirements for adjustable dimensional change, complicated working conditions and portability.
Description
technical field [0001] The invention relates to a portable mechanical dynamic seal airtight test device, which is suitable for testing the mechanical dynamic seals formed between the dynamic and static rings of some turbine pumps in the actual engineering field. Background technique [0002] At present, in the field of weaponry and equipment, the commonly used seal forms of turbo pumps mainly include static seals and dynamic seals. The static seal is realized by the cooperation of the seal ring with the shaft and the groove section; the dynamic seal is generally achieved by the mechanical seal pair. Realization, the sealing pair includes a moving ring, a static ring and other assemblies, and the dynamic sealing is realized by the moving ring and the static ring under the action of force under the working state. The detection of the dynamic seal at the present stage is to fit the dynamic ring and the static ring together before the assembly test, and perform an air-tight insp...
