The technical scheme of the utility model is that:

the utility model provides a floating sealing ring device of water pump, is including floating the seal seat, the inside of floating the seal seat is equipped with floating seal ring sum rubber circle respectively, the surface of floating the seal seat is equipped with the third draw-in groove, the surface cover of third draw-in groove is equipped with spacing spring.

The working principle of the technical scheme is as follows:

can prevent through limiting spring's setting and float a seat transition inflation, lead to sealed effect to reduce, or lead to floating seal ring and the separation of floating seal seat, lead to the damage of equipment, the clearance that is equipped with between two floating rings can make floating ring atress change distance to increase the leakproofness of whole device structure, the rubber circle of setting is installed in the installation circle that has the inclination, can realize fine leakproofness.

In a further technical scheme, a second clamping groove is formed in the middle of the inner surface of the floating seal seat, a second limiting ring is arranged on the outer ring of the floating seal ring, and the second clamping groove and the second limiting ring are mutually matched.

The second clamping groove is arranged to limit and fix the second limiting ring on one side of the floating ring, so that the offset is prevented, and the sealing effect is poor.

In a further technical scheme, the middle part of the floating seal ring is provided with an installation ring, the rubber ring is positioned between the floating seal seat and the installation ring, and the installation ring is provided with an inclination.

The rubber ring is arranged in the mounting ring with inclination, so that good sealing performance and good mobility can be realized, the sealing performance of the device is improved, and the technical problem of leakage in the prior art is solved.

In a further technical scheme, two sides of the outer surface of the floating seal ring are fixedly connected with first limiting rings, two sides of the inner surface of the floating seal seat are provided with first clamping grooves, and the first limiting rings are mutually matched with the first clamping grooves.

The first clamping groove clamps the first limiting ring on one side of the floating ring, so that the movable ring moves in the first clamping groove, and the device is prevented from being separated from the floating seal seat during normal work, and the equipment cannot work normally.

In a further technical scheme, the number of the floating seal rings is two, and a gap is formed between the two floating seal rings.

A gap is arranged between the two floating rings, so that the floating rings can change the distance under stress, the sealing performance of the whole device structure is improved, and no leakage or almost no leakage is achieved.

The utility model has the advantages that:

1. the second limiting ring is limited in position through the second clamping groove, the first clamping groove limits the first limiting ring of the floating ring, the floating ring can move in the floating seal seat, the rubber ring is installed in the inclined installation ring, good sealing performance is achieved, the distance of the floating ring can be changed due to stress of the gap between the two floating rings, the sealing performance of the device is improved, no leakage or no leakage basically is achieved, the running efficiency of the water pump is improved, the running time of the water pump is prolonged, energy conservation and emission reduction are achieved, and the running cost is reduced;

2. the setting through spacing spring can prevent to float and seal a seat transition inflation, leads to sealed effect to reduce, or leads to floating seal ring and the separation of floating seal seat, leads to the damage of equipment, influences the work efficiency of water pump, has improved the running cost.
