Detailed Description
The present utility model will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the present utility model, but are not intended to limit the utility model in any way. It should be noted that variations and modifications could be made by those skilled in the art without departing from the inventive concept. These are all within the scope of the present utility model.
Example 1
As shown in fig. 1-4, the utility model comprises a driving shaft 1, a driven shaft 7 and a shell, wherein the driving shaft 1 and the driven shaft 7 are arranged in the shell. The ceramic ring and the universal plug seal are arranged in the shell, and the ends of the driving shaft 1 and the driven shaft 7 penetrate through the ceramic ring and the universal plug seal and are rotatably connected to the shell.
In the use process of the gear pump, the driving shaft 1 drives the driving gear 8 to rotate when rotating, and simultaneously generates friction with the upper ceramic ring 10 of the driving shaft and the lower ceramic ring 13 of the driving shaft. When the driving gear 8 rotates, the driven gear 9 is driven to rotate in a meshing way, so that glue water can be extruded from the outlet of the gear pump. When the driven gear 9 rotates, the driven shaft 7 is driven to rotate so as to generate friction with the upper ceramic ring 14 of the driven shaft and the lower ceramic ring 15 of the driven shaft. When the driving gear 8 rotates to drive the driven gear 9 to mesh and rotate, glue can be extruded from the outlet of the gear pump, the pressure of the inner cavity of the gear pump can be increased, the upper sealing plug 11 of the driving shaft and the lower sealing plug 12 of the driving shaft can be expanded, so that the sealing effect is better, and meanwhile, the glue cannot flow onto the upper ceramic ring 14 of the driven shaft and the lower ceramic ring 15 of the driven shaft when the inside of the gear pump is pressurized by increasing the upper sealing plug 16 of the driven shaft and the lower sealing plug 17 of the driven shaft, so that the sealing effect is better.
Example 2
A dispenser comprising a gear pump with ceramic ring and flood seal of example 1.
