Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of pump machine suitable for the highly crystalline station of high-content
Tool seals, including connecting shaft 1, and the top and bottom of the connecting shaft 1 are symmetrically arranged with mechanical sealing linkage ring seat 2, described in top
The top left side of mechanical sealing linkage ring seat 2 is provided with mechanical seal matrix 3, the top right side setting of the mechanical seal matrix 3
There are pump cover 4, the bottom of the pump cover 4 and the top right side of mechanical seal matrix 3 to be provided with J-type sealing ring 7, the J-type sealing
The left bottom of circle 7 is provided with seal chamber 8, and seal chamber 8 is located on the right side of the surface of mechanical seal matrix 3, the seal chamber 8
Bottom is provided with dynamic and static ring 9, and dynamic and static ring 9, between mechanical seal matrix 3 and mechanical sealing linkage ring seat 2, the machinery is close
It is provided with rectangular channel 10 on the left of envelope matrix 3 and 7 contact position of J-type sealing ring.
Wherein, the bottom left of the top left side and bottom mechanical moving sealing ring seat 2 of the top mechanical sealing linkage ring seat 2
It is both provided with earflap 5, and two groups of earflaps 5 are respectively positioned on the left side of mechanical seal matrix 3, the surface crown of pump cover 4 described in two groups is equal
It is provided with mounting hole 6, the installation and fixation of pump cover 4, the outer wall of the J-type sealing ring 7 is convenient for be provided with pointed raised 71.
Operation principle：3 front end of mechanical seal matrix coordinated with pump cover 4 toward extension, and before mechanical seal matrix 3
A rectangular channel 10 is processed on the becket stretched, while the one end of J-type sealing ring 7 with round end is anchored in rectangular channel 10, wherein J
It is circle that type sealing ring 7, which is anchored to the end shape in the rectangular channel 10 of mechanical seal matrix 3, is contacted with mechanical sealing linkage ring seat 2
One end thickness it is gradually thinning, the one end for keeping J-type sealing ring 7 thin and mechanical sealing linkage ring seat 2 are bonded, then with mechanical seal
Dynamic and static ring 9 forms a seal chamber 8, and when mechanical seal operates, the flushing water with pressure enters seal chamber 8, then passes through
Rectangular channel 10 on J-type sealing ring 7, by seal chamber 8 to side medium, since the pressure of flushing water is higher than the pressure of side medium, together
When J-type sealing ring 7 have certain throttling action, the flushing water in seal chamber 8 can be uniformly across J-type sealing ring 7, it is therefore prevented that close
The convection current for sealing chamber 8 and side medium liquid, simultaneously because endlessly flushing water enters seal chamber 8, and then improves sound
The running environment of ring 9.Improve service life.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
