Preferably, the end face, far away from the stationary ring, of the movable ring component is connected with a synchronizing ring, the synchronizing ring is sleeved on the shaft sleeve, and the synchronizing ring is fixed with the movable ring component and drives the movable ring component to rotate synchronously.
Preferably, the end of the synchronizing ring, which is far away from the rotating ring assembly, is provided with a limiting ring, a spring is arranged between the limiting ring and the synchronizing ring, and the spring compresses the synchronizing ring to the rotating ring assembly.
Preferably, a gap is left between two adjacent layers of movable rings.
Preferably, the gap between two adjacent layers of movable rings is 0.5-1 mm.
The spring mechanical seal compensating ring assembly has the beneficial effects that: the movable ring in the prior art is changed to be of an integral structure, the movable ring is split into multiple layers, sealing with the static ring is achieved, the compensation rings are arranged among the multiple layers of motor cars, and the sealing effect and the service life of the movable ring are improved.
Drawings
Fig. 1 is a schematic structural diagram of a spring mechanical seal compensating ring assembly according to the technical solution of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
As shown in fig. 1, the mechanical spring seal compensating ring assembly according to the technical solution of the present invention includes a fixed flange 2 sleeved on a shaft sleeve 1, a stationary ring 3 disposed between the fixed flange 2 and the shaft sleeve 1, and a movable ring assembly 7 in contact with a sealing surface of the stationary ring 3 and sleeved on the shaft sleeve 1. The movable ring assembly 7 comprises a plurality of layers of movable rings 71 which are sleeved with each other, all the movable rings 71 and the shaft sleeve 1 rotate synchronously, and the side surfaces of all the movable rings 71 close to the end of the static ring 3 are in contact with the static ring 3 to realize sealing. The movable rings 71 of the layers which are mutually sleeved are compensated, the sealing between the two movable rings 71 cannot be influenced mutually, when one movable ring has the problems of deformation and the like, the sealing effect of other movable rings is not influenced, so that the performance and the effect of mechanical sealing are effectively improved, the failure rate is reduced, or after one movable ring or a plurality of movable rings are damaged, at least one movable ring can be ensured to realize sealing, although the sealing effect is not good enough, the state can be maintained, and the overhaul time can be obtained for overhaul personnel.
The end face, far away from the static ring 3, of the movable ring assembly 7 is connected with a synchronizing ring 6, the synchronizing ring 6 is sleeved on the shaft sleeve 1, and the synchronizing ring 6 and the movable ring assembly 7 are fixed and drive the movable ring assembly 7 to rotate synchronously. The end, far away from the moving ring assembly 7, of the synchronizing ring 6 is provided with a limiting ring 4, a spring 5 is arranged between the limiting ring 4 and the synchronizing ring 6, and the spring 5 compresses the synchronizing ring 6 to the moving ring assembly 7. A gap is left between two adjacent layers of movable rings 71. The gap between two adjacent layers of movable rings 71 is 0.5-1 mm.
In the technology, the movable ring assembly 7 consisting of the multiple layers of movable rings 71 is contacted with the static ring to realize sealing. The movable rings act independently to realize sealing and compensate each other on the sealing surface.
It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by one of ordinary skill in the art and related arts based on the embodiments of the present invention without any creative effort, shall fall within the protection scope of the present invention. Structures, devices, and methods of operation not specifically described or illustrated herein are generally practiced in the art without specific recitation or limitation.
