Description
Technical Field
The utility model relates to a pump with an impeller sealing ring, which improves the problems of the traditional structure of the impeller sealing ring of a double suction pump, such as large volume loss and leakage, influence on the efficiency of the water pump, disassembly and assembly, and the like.
Background
Now, a conventional seal ring is fitted with an impeller (fig. 1), which is a flat seal, and the pressure across the gap between the impeller and the seal ring is different during operation of the pump, so that liquid leaks from the high pressure side to the low pressure side through the gap. Some of the energy liquid obtained from the pump is not completely transported away, and the energy is lost in the form of a throttling loss, which affects efficiency.
Disclosure of Invention
The utility model aims to design a pump with an impeller sealing ring, which can improve the defects of the traditional sealing ring structure, reduce the volume loss, improve the volumetric efficiency and is simpler, faster and more reliable to use. The utility model designs a pump with an impeller sealing ring, which comprises a pump body, an impeller and a sealing ring, and is characterized in that the sealing ring consists of a left half ring and a right half ring, a labyrinth groove is arranged at the matching surface of the sealing ring and the impeller, a corresponding labyrinth groove is arranged at the matching surface of the impeller, and the labyrinth groove on the sealing ring is embedded in the labyrinth groove on the impeller. The left half ring and the right half ring are respectively connected and fixed with the pump body and the pump cover by an inner hexagonal cylindrical head screw. The utility model has the advantages that: compared with the traditional structure, the novel centrifugal pump has the advantages of safety, reliability, simplicity, rapidness, energy conservation, consumption reduction, operation of the pump at optimal efficiency, prolonged service life, reduction of operation and maintenance costs of the centrifugal pump, improvement of economic benefits of enterprises, and reliability in structure, and is a novel structure worthy of wide application.

Detailed Description
The following detailed description of the utility model, taken in conjunction with the accompanying drawings, will provide those skilled in the art with a more readily understood understanding of how the utility model may be practiced. While the present utility model has been described in connection with the preferred embodiments thereof, these embodiments are set forth only and are not intended to limit the scope of the utility model.
The pump with the impeller sealing ring comprises a pump body 1, an impeller 2 and a sealing ring 3, and is characterized in that the sealing ring consists of a left half ring and a right half ring, a labyrinth groove 4 is arranged at the matching surface of the sealing ring and the impeller, a corresponding labyrinth groove 5 is arranged at the matching surface of the impeller, and the labyrinth groove on the sealing ring is embedded in the labyrinth groove on the impeller. The left half ring and the right half ring are respectively connected and fixed with the pump body 1 and the pump cover 7 by an inner hexagonal cylindrical head screw 6.
When the impeller rotates, liquid enters the first-stage groove, the direction of the water flow is doubled compared with the length of the water flow in fig. 1, so that the flow resistance of the liquid is greatly increased, the leakage amount of the liquid is reduced, the energy loss is reduced, the volumetric efficiency is improved, the total efficiency eta=eta m (mechanical efficiency) ×eta v (volumetric efficiency) ×eta h (hydraulic efficiency) is improved, and the total efficiency is improved. The power consumed by the pump is inversely proportional to the efficiency of the pump, and the power requirement can be reduced by increasing the efficiency for the output of the head corresponding to the same flow. The sealing ring consists of a left half ring and a right half ring, and is respectively connected and fixed with the pump body and the pump cover by an inner hexagonal cylindrical head screw, so that the assembly and the disassembly are convenient.
Claims (2)
1. The pump with the impeller sealing ring comprises a pump body, an impeller and the sealing ring, and is characterized in that the sealing ring consists of a left half ring and a right half ring, a labyrinth groove is arranged at the matching surface of the sealing ring and the impeller, a corresponding labyrinth groove is arranged at the matching surface of the impeller, and the labyrinth groove on the sealing ring is embedded in the labyrinth groove on the impeller.
2. The pump with impeller seal ring of claim 1, wherein the left half ring and the right half ring are respectively connected and fixed with the pump body and the pump cover by a hexagon socket head cap screw.
