FIG. 2 is an enlarged view of the utility model at A in FIG. 1;
in the figure: 1. pump shell, 2, impeller, 3, front guard board, 4, through hole, 5, sealed water cavity, 6, flushing water pipe, 7, inlet pipe, 8, outlet pipe, 9, water conduit, 10, sand-water separator, 11, return pipe.
Detailed Description
The technical solutions of the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1-2, a novel front guard plate sealing structure comprises a pump shell 1 with a cavity and an impeller 2 rotatably arranged in the pump shell 1, wherein a front guard plate 3 is arranged in the pump shell 1, the impeller 2 and the front guard plate 3 are provided with axial gaps, the front guard plate 3 is provided with a plurality of through holes 4, the front guard plate 3 and the pump shell 1 form a sealing water cavity 5, the through holes 4 are communicated with the axial gaps and the sealing water cavity 5, and a flushing water pipe 6 is communicated with the sealing water cavity 5 by the shell and is used for supplying water to the sealing water cavity 5.
In this embodiment, the impeller 2 and the front guard plate 3 have an axial gap, and when the water pump is running, because the water contains impurities such as soil, the axial gap between the impeller 2 and the front guard plate 3 is easy to enter the impurities such as mud, thereby increasing the abrasion of the impeller 2 and the front guard plate 3 and reducing the service lives of the impeller 2 and the front guard plate 3. In this embodiment, the sealing structure for cleaning the axial gap is provided, when the water pump actually works, the flushing water pipe 6 injects clean water into the sealing water cavity 5, so that the pressure of the sealing water cavity 5 is higher than the gap pressure of the impeller 2 and the front guard plate 3, at this time, the pressure water of the sealing water cavity 5 enters the gap between the impeller 2 and the front guard plate 3 through the through hole 4 on the front guard plate 3, and the slurry in the gap is flushed away, so that the gap is filled with clean water when the water pump is in operation, and the abrasion loss of the impeller 2 and the front guard plate 3 can be greatly reduced.
