Abstract
The utility model relates to the technical field of mechanical engineering pumps, in particular to a sealing structure of a sealing ring for a pump. The sealing structure of the sealing ring for the pump is provided with a pump body, an impeller, the sealing ring and a pin shaft. The pump body is fixedly connected with the impeller through the sealing ring, and the sealing ring is fixedly connected with the pump body through the pin shaft. The sealing structure of the sealing ring for the pump is characterized in that a sealing boss is arranged at the axial force output outer end of the pump body, a sealing seam allowance is arranged at one end of an inner circle of the sealing ring, and the sealing seam allowance is matched with the sealing boss. The sealing structure of the sealing ring of the pump is beneficial to bearing partial axial force by clamping of the sealing seam allowance and the sealing boss, abrasion of the pin shaft is reduced, and the sealing ring is prevented from falling off due to excessive axial force, and operational service life of the pump body is prolonged. With the structure, the sealing structure of the sealing ring for the pump has the advantages of being simple in structure, convenient to operate, big in axial force bearing, high in sealing performance, long in service life and the like.
Description
Technical field
The utility model relates to mechanical engineering pump technical field, specifically a kind of pump sealing configuration of seal ring.
Background technique
At present, between traditional impeller and the pump housing in order to reach sealing effect, generally use seal ring seal, and, usually with bearing pin seal ring is fixed on the pump housing in order to increase the axial force of seal ring, in long-term operation process, the axial force of pump shaft is born by bearing pin fully, causes the bearing pin serious wear, in case the bearing pin fracture, seal ring very easily comes off under responsive to axial force, finally causes the seal failure of pump.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to operate, the axial force carrying is large, sealability is high, the pump of long service life is with the sealing configuration of seal ring.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of pump sealing configuration of seal ring, be provided with the pump housing, impeller, seal ring and bearing pin, the pump housing is fixedly connected with impeller through seal ring, seal ring is fixedly connected with the pump housing through bearing pin, the axial force output outer end that it is characterized in that the pump housing is provided with seal boss, inner circle one end of seal ring is provided with the sealing seam, the sealing seam matches with seal boss, be beneficial to the engaging by sealing seam and seal boss, bear section axial power, alleviate the wearing and tearing of bearing pin, avoid seal ring to come off because axial force is excessive, prolong the service life of the pump housing.
The utility model can be provided with the ring packing groove at the seal ring inwall, is provided with seal ring in the ring packing groove, and seal ring is fixedly connected with the pump housing, is beneficial to further improve the sealability between the pump housing and the impeller.
The utility model is owing to adopting said structure, have simple in structure, easy to operate, the axial force carrying is large, the advantages such as sealability is high, long service life.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
Reference character: impeller 1, bearing pin 2, seal ring 3, seal ring 4, the pump housing 5, sealing seam 6, seal boss 7.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in drawings, a kind of pump sealing configuration of seal ring, be provided with the pump housing 5, impeller 1, seal ring 3 and bearing pin 2, the pump housing 5 is fixedly connected with impeller 1 through seal ring 3, seal ring 3 is fixedly connected with the pump housing 5 through bearing pin 2, the axial force output outer end that it is characterized in that the pump housing 5 is provided with seal boss 7, inner circle one end of seal ring 3 is provided with sealing seam 6, sealing seam 6 matches with seal boss 7, be beneficial to the engaging by sealing seam 6 and seal boss 7, bear section axial power, alleviate the wearing and tearing of bearing pin, avoid seal ring to come off because axial force is excessive, prolong the service life of the pump housing.
The utility model can be provided with the ring packing groove at seal ring 3 inwalls, is provided with seal ring 4 in the ring packing groove, and seal ring 4 is fixedly connected with the pump housing 5, is beneficial to further improve the sealability between the pump housing 5 and the impeller 1.
The utility model is in running, and the axial force of pump is born by bearing pin 2, sealing seam 6 and seal boss 7, thereby has avoided causing seal ring 3 to come off because the wearing and tearing of bearing pin 2 are excessive.
The utility model is owing to adopting said structure, have simple in structure, easy to operate, the axial force carrying is large, the advantages such as sealability is high, long service life.
Claims (2)
