Abstract
The utility model relates to a double entry pump seal structure, including the pump body and the pump cover of double entry pump, its characterized in that: a groove is formed in the middle opening surface of the pump body of the double-suction pump according to a sealing track, a sealing ring is embedded into the groove, and the pump body of the double-suction pump and the pump cover are installed and fixed in a matched mode. The utility model has the advantages that the product is standardized: the groove is machined by a numerical control machine tool, the sealing ring is customized, the sealing structure and the sealing mode used by each type of water pump are completely the same, and product standardization is realized. The sealing performance is good: the sealing of the groove structure can improve the compression resistance, and the sealing ring is not easy to extrude under high pressure. The integral sealing ring structure ensures uniform sealing and ensures good sealing performance of the product.
Description
Technical Field
The utility model relates to a double entry pump seal structure.
Background
The structure of the prior art is shown as figure one: pump cover, pump body, sealing gasket, figure 2 is the layout diagram of the sealing gasket on the sealing surface of the pump cover of the pump body,
the working principle is as follows: as shown in fig. 1 and 2, pump body 12 and pump cover 11 are assembled, and in order to ensure the water pump sealing, a sealing gasket 13 is arranged between pump body 12 and pump cover 11, and the shape of the sealing gasket is shown as a track indicated by a in fig. 3. The sealing gasket 13 used by the double-suction pump produced in the factory is made of raw material tape (PTFE), an assembler cuts out a certain length of the raw material tape and places the raw material tape according to the track of a figure 3, and finally the pump body 12 and the pump cover 11 are installed in a matched mode. The existing structure has certain defects: product non-standardization: by using the raw material belt sealing structure, the length, the shape and the placement position of the raw material belt depend on the personal operation experience of an assembler, the assembly effect is different every time, and the integral sealing performance of the product is not uniform. Poor sealing performance: for the double suction pump with a little higher pressure, the raw material belt is easily extruded by the high-pressure water in the pump cavity, and the water pump leaks.
Disclosure of Invention
The utility model aims at improving the sealing mode of the pump body pump cover fitting surface of double entry pump, making water pump sealing performance all obtain stably, improving the installation effectiveness, realizing the standardized operation of product. The utility model relates to a double entry pump seal structure, including the pump body and the pump cover of double entry pump, its characterized in that: a groove is formed in the middle opening surface of the pump body of the double-suction pump according to a sealing track, a sealing ring is embedded into the groove, and the pump body of the double-suction pump and the pump cover are installed and fixed in a matched mode. The utility model has the advantages that the product is standardized: the groove is machined by a numerical control machine tool, the sealing ring is customized, the sealing structure and the sealing mode used by each type of water pump are completely the same, and product standardization is realized. The sealing performance is good: the sealing of the groove structure can improve the compression resistance, and the sealing ring is not easy to extrude under high pressure. The integral sealing ring structure ensures uniform sealing and ensures good sealing performance of the product.
Drawings
Fig. 1 is a schematic structural diagram of the prior art.
Fig. 2 is an enlarged view of the sealing structure of fig. 1.
Figure 3 is the sealing track of the double suction pump of the present invention.
Fig. 4 is a schematic sectional view of a sealing ring in use according to the present invention.
Detailed Description
A double entry pump seal structure in figure, including pump body 1 and the pump cover 2 of double entry pump, its characterized in that: a groove 3 is formed in the middle opening surface of the pump body of the double-suction pump according to a sealing track, a sealing ring 4 is embedded into the groove, and the pump body of the double-suction pump and the pump cover are installed and fixed in a matched mode.
In order to ensure the sealing of the double suction pump, a sealing ring is arranged between the pump body and the pump cover, and the sealing ring is arranged on the middle opening surface of the pump body in a mode that a groove is milled by a numerical control machine according to a sealing track A shown in figure 3. The sealing ring is arranged in the groove, and finally the pump body and the pump cover are arranged in a matched mode, and sealing is achieved through the elastic mechanism of the sealing ring. Therefore, the grooves are machined through a numerical control machine tool, the sealing rings are customized, the sealing structure and the sealing mode used by each type of water pump are completely the same, and product standardization is achieved. The sealing performance is good: the sealing of the groove structure can improve the compression resistance, and the sealing ring is not easy to extrude under high pressure. The integral sealing ring structure ensures uniform sealing and ensures good sealing performance of the product.
