Description

Technical Field

[0001] The utility model relates to the technical field of water pump sealing rotating rings, in particular to a water pump sealing rotating ring. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals, as well as liquids containing suspended solids. The rotating ring is an indispensable structure in the water pump.

[0003] When the sealing rotating ring currently on the market is used inside a water pump, its functionality is relatively simple and it can only passively perform sealing rotation. When the water pump outside the sealing rotating ring starts working, it can only use the impeller to draw liquid into the pump casing, then discharge it, and take away the heat, and then achieve the cooling effect. It cannot achieve the purpose of autonomous driving. The existing dynamic ring only has a sealing function, not a driving function, and there are certain limitations in its application.

[0004] Chinese patent application number CN202022379949.0 discloses a water pump sealing rotating ring with a driving function, comprising a first sealing lip of the moving ring, a driving paddle and a second sealing lip of the moving ring, wherein the second sealing lip of the moving ring is arranged inside the first sealing lip of the moving ring, a driving paddle is arranged between the first sealing lip of the moving ring and the second sealing lip of the moving ring, and the driving paddle is fixedly connected to the outside of the first sealing lip of the moving ring and the second sealing lip of the moving ring.

[0005] Although the above patents can solve the corresponding technical problems, there are still certain defects in the use process:

[0006] When the sealing rotating ring is driven autonomously and realizes circulating cooling with the sealing fixed ring, the friction between the sealing rotating ring and the sealing fixed ring cannot be reduced, thereby failing to enhance the autonomous driving effect of the sealing rotating ring and the circulating cooling effect of the sealing rotating ring and the sealing fixed ring. Utility Model Content

[0007] The utility model aims to provide a water pump sealing rotating ring in view of the defects and shortcomings of the prior art.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A water pump sealing rotating ring, comprising a first sealing lip of the dynamic ring, a second sealing lip of the dynamic ring arranged inside the first sealing lip of the dynamic ring, a plurality of rotating ring circulating cooling grooves equidistantly arranged between the first sealing lip of the dynamic ring and the second sealing lip of the dynamic ring, a driving paddle arranged between the first sealing lip of the dynamic ring and the second sealing lip of the dynamic ring and located in the circulating cooling groove of the rotating ring, and also comprising an auxiliary device arranged between the first sealing lip of the dynamic ring and the second sealing lip of the dynamic ring and close to the end face of the external sealing fixed ring for reducing the friction between the sealing rotating ring and the sealing fixed ring when the sealing rotating ring is autonomously driven and realizes circulating cooling with the sealing fixed ring, thereby enhancing the autonomous driving effect of the sealing rotating ring and improving the circulating cooling effect of the sealing rotating ring and the sealing fixed ring.

[0010] A further improvement is that the auxiliary device includes a first auxiliary layer with a predetermined friction coefficient and a predetermined thermal conductivity coefficient, which is arranged on the end surface of the first sealing lip of the dynamic ring close to the external sealing fixed ring, and a second auxiliary layer with a predetermined friction coefficient and a predetermined thermal conductivity coefficient, which is arranged on the end surface of the second sealing lip of the dynamic ring close to the external sealing fixed ring, and the thickness of the second auxiliary layer is the same as the thickness of the first auxiliary layer.

[0011] A further improvement is that the first auxiliary layer is a first silicon carbide layer used to improve the temperature resistance and wear resistance of the first auxiliary layer so as to increase the service life of the first auxiliary layer.

[0012] A further improvement is that the second auxiliary layer is a second silicon carbide layer used to improve the temperature resistance and wear resistance of the second auxiliary layer so as to increase the service life of the second auxiliary layer.

[0013] A further improvement is that the thickness of the first auxiliary layer is 1-5 mm.

[0014] After adopting the above technical scheme, the beneficial effect of the utility model is: when the sealing rotating ring is autonomously driven and realizes circulating cooling with the sealing fixed ring, the friction between the sealing rotating ring and the sealing fixed ring can be reduced, thereby enhancing the effect of the autonomous driving of the sealing rotating ring and improving the circulating cooling effect of the sealing rotating ring and the sealing fixed ring.
